The invention relates to a handlebar localisation grip, for vehicles steerable with a handlebar, preferably for two-wheeled vehicles. The device can be mounted on a handlebar and may be used to localise a parked vehicle in a large parking, garage or shed by the provision of a recognisable signal. The invention further relates to a vehicle, a vehicle localisation assembly, a method to localise a vehicle, optionally with a vehicle localisation assembly, and a method to provide localisation functionality to a vehicle having a handlebar.

An example of such a handlebar device is known from prior art, for example WO 2016/185247 A1. This publication discloses a navigation device comprising a haptic and/or acoustic signalling device fastened on a handlebar and a handlebar grip. Through activation of the signalling device in a respective left or right handlebar grip, a navigation instruction is provided to the user holding these handlebar grips. Additionally, a locating method for locating the navigation device is disclosed, wherein the signalling device is triggered to provide an acoustic signal, which can preferably be heard over a distance of at least 5 meters.

It has, however, been found that such an acoustic signal is difficult to notice due to its limited salience, particular at larger distances or in crowded and/or noisy environments, such as a bicycle shed at a train station. Additionally, if noticed, it is difficult to localise the vehicle due to echoic reflections, especially in underground bicycle sheds.

Additionally, especially in other vehicles such as mopeds, motorcycles and (mobility) scooters, localisation functionality is often lacking due to the relative complexity of integrating the functionality into such a vehicle. In addition to the wiring required to provide a localisation module with energy, the GPS and communication antennas require a position where they are able to pick up a signal, favourably outside of the frame of the vehicle, since a metal frame acts as a Faraday cage which could limit the range of the antennas and therefore hamper connectivity.

It is therefore an object of the invention to provide a device that may emit a localisation signal that lacks the above-mentioned disadvantages or at least to provide an alternative, preferably an alternative with an improved salience which is easier to locate in a larger number of environments.

The handlebar localisation grip according to the present invention allows for a relatively simple installation during production or retrofitting. As a handlebar is inherently provided on an accessible place, the handlebar localisation grip can be mounted easily on a vehicle. As such, any conventional vehicle, that is, a vehicle not equipped with any localisation or remote management functionality, but that is equipped with a handle bar grip, may easily be converted into a localisable vehicle. As such, the handlebar localisation grip may be installed on a bicycle, moped, scooter, motorbike, but also on vehicles for people with reduced mobility, such as mobility scooters, rollators and wheelchairs. The handlebar localisation grip may be particularly advantageous for rental vehicles, shared vehicles and courtesy vehicles that are temporarily provided to different users.

A benefit of the present handlebar localisation grip is that two different types of localisation information can be provided. As a first, a position of the handlebar localisation grip, and therefore of the vehicle, may be provided towards a user nearby, e.g. by means of the optical vehicle localisation signal. The detection of such a relative position, e.g. a relative position between the user and the vehicle with the grip that provides the optical vehicle localisation signal, may be beneficial for users aiming to find their vehicle, for example to find a specific rental vehicle for the user between a number of different rental vehicles. As a second, an absolute position of the handlebar localisation grip, and therefore of the vehicle, may be provided on the basis of the geolocation coordinates. The detection of this absolute position may be beneficial for a remote user, for example a fleet owner monitoring the positions of vehicles in a fleet, for example for remotely monitoring the positions of a fleet of rental vehicles.

The handlebar localisation grip may be completely stand-alone, which further eases retrofitting. With stand-alone, it is meant that the handlebar localisation grip can function on itself without requiring any connection to the vehicle, other than a mechanical connection to secure the position of the handlebar localisation with respect to the vehicle, once installed. In particular, the stand-alone handlebar localisation grip may not require any electrical connection with the vehicle, for example to supply electrical power to the handlebar localisation grip from the vehicle, and may not rely on any sensors provided in the vehicle. As such, localisation functionality may be provided by only replacing a handlebar grip, such that it may not be necessary to replace a complete handlebar, to connect cables and/or to make other modifications to the vehicle, for example to the frame. Therewith significant savings on labour costs may be achieved, especially for owners of larger vehicle fleets, and the handlebar localisation grip may be applicable universally, without being limited to only several specific types of vehicles.

As the handlebar localisation grip may be provided on a position of a conventional handlebar grip, there is no need for additional space on the handlebar. This may be especially advantageous for vehicles having smaller handlebars, such as children’s bikes, rollators and wheelchairs.

Additionally, the handlebar localisation grip may be located on the outside of the frame and may thereby provide an attractive location to accommodate communication antennas. Therewith, the handlebar localisation grip offers an attractive solution for making any vehicle with a handlebar localisable, both for the user of the vehicle as for a remote owner or supervisor. An existing fleet of a vehicle rental or sharing service, hospital or nursing home may be provided with localisation functionality without requiring significant modifications.

A mixed fleet of vehicle types may be localised using the same handlebar localisation grips. Thus, a user-friendly solution is provided to vehicle owners, supervisors and users, including elderly, children and people with disabilities.

With the device according to the invention, the localisation signal is provided optically, such that the maximum reach of the signal may be practically equal to the line-of-sight of the user, and that the noise generated in the environment is no longer a hindrance. Additionally, the influence of echoic reflections is limited. By doing so, the saliency of the device is increased, and the vehicle can be detected at larger distances and in crowded or noisy environments.

The device may thereby achieve the objective of the invention since it can be deployed in a larger number of environments, especially in environments where a high saliency is required, such as busy, noisy or crowded environments.

With the geolocation coordinates of the handlebar localisation grip provided by the geolocation module, using a global navigation satellite system, the position of the vehicle could be indicated to the user, e.g. a remote user, not in the proximity of the handlebar localisation grip by means of a map, position indicator, arrow or beep tone. Thus, through the geolocation module, the actual position of the handlebar localisation grip could be determined by other means than the signal coming from the first signalisation module. This could be advantageous for localisation purposes, if the user does not remember an approximate parking position of the vehicle while the vehicle is parked outside the direct line-of-sight of the user.

The present invention provides a handlebar localisation grip, for providing a vehicle with localisation functionality, configured to indicate a position of a vehicle, comprising:

- a handlebar grip, configured to be mounted on a handlebar of a vehicle,

- a first signalling module, configured to provide an optical vehicle localisation signal,

- a geolocation module, configured to provide geolocation coordinates of the handlebar localisation grip, using a global navigation satellite system,

- a control module, connected to the first signalling module and the geolocation module, wherein the control module is configured to activate the first signalling module to provide the vehicle localisation signal upon receipt of a localisation command by the communication module and/or to process the geolocation coordinates, and

- a communication module, connected to the control unit and configured to receive and/or send wireless commands, such as a wireless localisation command and/or a geolocation coordinates, from/to an external device, wherein the first signalling module, the geolocation module, the control module and the communication module are integrated in the handlebar grip.

The handlebar localisation grip is configured to be attached to a handlebar tube of a vehicle by means of the handlebar grip. The shape of a handlebar grip according to the present invention may be substantially cylindrical, with a circular cross-section. The handlebar grip may further comprise a tapered, rectangular, polygonal, ellipsoidal or varying cross- section. The outer shape of the handlebar grip could, for example be adapted to the shape of a human hand for advantageous ergonomics.

In an embodiment, the handlebar localisation grip comprises an inner sleeve along a sleeve axis, for example along a longitudinal axis of the device. The sleeve extends through at least a portion of the interior of the handlebar grip and may be used to accommodate a portion of a handlebar of a vehicle.

In an embodiment, the sleeve may extend through the entire device, thus forming a trough hole, such that the handlebar can protrude herein, from two sides along the sleeve axis. This configuration could be advantageous to allow for the mechanical connection of other elements, such a handlebar weights, on the end of the handlebar.

This sleeve may, for example be cylindrical, with a circular cross-section. The sleeve may further have a tapered, rectangular, polygonal, ellipsoidal or varying cross-section, to accommodate handlebars of various types of vehicles. For example, the shape and outer dimensions of the handlebar of a motorcycle might substantially differ from the shape and the outer dimensions of the handlebar of a bicycle.

In an advantageous embodiment, the smallest inner diameter of the sleeve is equal to or larger than an outer diameter of the handlebar of a vehicle, such that the device can be easily mounted on the handlebar of the vehicle. As such, the handlebar localisation grip may be mounted on the handlebar of the vehicle in a similar way as a regular handlebar grip. The handlebar localisation grip may be provided with additional fixation elements to provide for a firm attachment of the handlebar localisation grip.

In an embodiment, the handlebar localisation grip could be provided with at least one clamping element to provide for attachment on the handlebar by means of friction. For example, a ring portion of the handlebar grip could extend laterally an outer end of the handlebar grip, therewith providing a clamping area. By providing at least one clamping element around the ring portion of the handlebar grip, for example a hose clamp, a clamping force is generated, which provides a firm attachment of the handlebar localisation grip to the handlebar. In an embodiment, the clamping element may comprise two semi-circular elements that together form a clamping element around a ring portion of the handlebar grip, wherein the ring elements have an inner diameter that is slightly smaller than the outer diameter of the ring portion of the handlebar grip.

In a further or alternative embodiment, the handlebar localisation grip could be provided with at least one first aperture in the handlebar grip, which extends into the sleeve.

At least one first aperture may be arranged to accommodate a fixation element such as a bolt, a screw or a pin. At least a portion of at least one first aperture may be provided with a thread, such that a screw or bolt could be introduced into it.

In a further embodiment, a first aperture may extend from the outside of the handlebar grip into the sleeve, such that a fixation element can be drawn through that first aperture from the outside of the handlebar grip into the sleeve. The fixation element may have sufficient length, such that it can extend from the first aperture into the sleeve. As such, the fixation element may come in contact with the handlebar, thereby causing a friction or clamping force between the fixation element and the handlebar, which provides a firm attachment of the handlebar localisation grip to the handlebar by means of force locking.

In a further embodiment, a second aperture may be provided in the handlebar, arranged on a position that corresponds with a position of the first aperture in the handlebar grip, such that the fixation element could extend from the first aperture through the sleeve into the second aperture in the handlebar, thereby preventing removal of the handlebar localisation grip by means of shape locking.

In a further embodiment, the sleeve may have an inner diameter substantially larger than that of the handlebar of a vehicle, while the sleeve allows for the insertion of inlay elements. These inlay elements could, for example have the same shape as the sleeve, with an outer diameter of the inlay element equal to the inner diameter of the sleeve, and an inner diameter of the inlay element equal to the outer diameter of the handlebar, and thereby effectively reduce the inner diameter of the sleeve, such that, the same sleeve can accommodate different types of handlebars.

The handlebar localisation grip according to the present invention comprises a first signalling module which is configured to provide an optical vehicle localisation signal to a user of the device, in order to enable a user to localise a vehicle.

The handlebar localisation grip according to the present invention further comprises a communication module, which is configured to communicate with an external device, to receive and/or send wireless commands, for example wireless localisation commands. These commands could be issued by a user of the device, in order to be able to localise the vehicle. The commands could be sent by a user from an external device, such as a mobile phone, smart phone or a remote control. The external device may be a device of the user of the vehicle, such as a mobile phone of the user. Alternatively or additionally, the external device may be a device of a remote operator, such as a fleet management system of a fleet owner.

The command is preferably sent using communication technology which does not limit the maximum reach of the command, such that the vehicle can be localised from any distance. Examples of such wireless communication technology are wireless internet connections via WiFi, UMTS, LTE, 5G, Bluetooth, infrared, ZigBee or LoRaWAN.

The handlebar localisation grip according to the present invention further comprises a control module, connected to at least the communication module, the geolocation module and the first signalling module. The control module is configured to activate the first signalling module to provide the vehicle localisation signal upon the reception of a localisation command by the communication module. The control module is further configured to process the geolocation coordinates provided by the geolocation module. Additionally, the control module may be configured to process input signals from other connected modules, and may be configured to forward signals to at least one of the first signalling module or the communication module if necessary.

In an embodiment, the first signalling module comprises at least one light-emitting element, such as a light emitting diode. The light-emitting element may advantageously be located nearby an outer end of a handlebar grip, as such a location may be advantageous for the visibility of the element. The light-emitting element may comprise a SMD or COB type LED element, as these types are capable of providing a high brightness while requiring a low amount of energy, which is advantageous for long-term use. However, other types of light- emitting elements could be incorporated as well to facilitate easy replacements or maintenance, adjusted to local availability. Such types of light-emitting elements are, for example incandescent light bulbs and halogen lamps. The first signalling module could further comprise other types of light emitting elements, such as a text sign, a laser element or a projection element. Preferably, the at least one light emitting element is configured to emit light having wavelengths between 350 nm and 750 nm.

In an embodiment, the colour of the light comprised in the optical localisation signal by the at least one light emitting element is a colour for which the human visual system has a high sensitivity. In a further embodiment, a colour can be provided for which the at least one light emitting element can deliver a high brightness, which would improve the visibility of the handlebar localisation grip. The colour emitted by the at least one light emitting element can, for example be substantially white, as the majority of light emitting elements is available in this colour, and RGB-type LED elements are capable of providing maximum brightness when emitting this colour. In an embodiment, the brightness and/or the colour of the light emitted by the at least one light emitting element is configured to be adjusted by the user of the device. In this embodiment, the control module may be configured to control one or more properties of the light emitted by the first signalling module, such as the wavelength or brightness thereof.

In an embodiment, the properties of activations of the first signalling module with the control module, upon receipt of a localisation indication command by the communication module, may be adjusted by the user. In such an embodiment, the first signalling module may be configured to emit a flashing optical localisation signal, and the control module may be configured to control an amount of flashes, a duration of respective flashes and a duration of pauses in between the respective flashes by subsequent activation and deactivation of the first signalling module. Having adjustable light and activation properties may be advantageous for personalisation of the localisation signal, which could provide recognisability in a large shed, garage or parking where different vehicles are localised by multiple users at the same time, each having different localisation signals.

In an embodiment, the handlebar localisation grip further comprises a coupling module, which is configured to be detected by the external device in order to allow for the initiation of a wireless connection between the handlebar localisation grip and the external device.

As the handlebar localisation grips is provided on the handlebar, it may be easy to reach by a user, such that coupling between the external device and the handlebar localisation grip may be performed easily. This is especially advantageous for vehicles that need to be coupled often with different external devices, for example for vehicles that are used by different users.

The coupling module in the handlebar localisation grip is therefore especially advantageous for rental vehicles, shared vehicles and courtesy vehicles that are temporarily provided to different users, to enable convenient coupling when a new user starts using the vehicle.

The coupling module could, for example comprise a QR-code located on an outer edge of the handlebar grip, containing a link to a coupling instruction, website or application. By scanning the QR code with the external device, the user would be able to set up a set up a wireless connection between the external device and the communication module of the handlebar localisation grip. This could, for example be achieved by allowing the user to follow the provided instructions, by allowing the user to alter the configuration of the handlebar localisation grip through a website or an application, or by allowing the user to start an automated installation procedure after visiting the website or installing the application. In a further embodiment, the coupling module might automatically initiate a wireless connection between a handlebar localisation grip and an external device. This initiation may take place using the same wireless communication protocol or technology as the wireless connection that is set up between a communication module and an external device. Alternatively, the initiation of the wireless communication may take place by means of a different wireless communication protocol or technology, such as near-field communication (NFC) or Bluetooth. In an embodiment, the coupling module and the communication module are comprised in a single device. Hereby, the amount of antennas and components within the handlebar localisation grip may be reduced, which may beneficial as the volume required for all modules is advantageously as small as possible, in order to have a maximum outer diameter of the handlebar grip that is ergonomic to a human hand, while a minimum inner diameter of the inner sleeve in the handlebar grip should be large enough to accommodate a handlebar of a vehicle.

As a specific external device may be coupled to a specific handlebar localisation grip, interference with handlebar localisation grips from third parties may be avoided. Alternatively, the coupling module may be configured to allow coupling of multiple external devices. For example, the handlebar localisation grip may be coupled to both the external device of the user of the vehicle, e.g. to the mobile phone of the user, and to the external device of a remote operator, for example to a fleet management system of a fleet owner. That way, multiple external devices may be used to localise the vehicle. In such an embodiment, the user may restrict coupling to specific external devices, for example by settings in the control module.

In an embodiment, the coupling module further comprises an authentication element, such as a fingerprint reader to restrict coupling to specific external devices. Alternatively, authentication may be performed through the external device, for example through a finger print reader, a face recognition camera or keyboard on the external device.

In an embodiment, the handlebar localisation grip further comprises an energy module, connected to at least one of the first signalling module, the communication module and/or the control module, which is configured to generate and/or store energy that is required for powering at least of the connected modules and/or the at least one light emitting element. The energy module may, for example, comprise at least one battery. The at least one battery may advantageously be arranged inside the handlebar grip. The battery may comprise a lithium-ion or lithium-polymer battery, since such batteries provide a high energy density in a relatively low volume, which may be advantageous for reducing the volume required for the modules within the handlebar grip. Alternatively, the battery could comprise a standard type zinc-carbon or alkaline battery, such as an AA or AAA type battery, in order to facilitate easy replacement by the user.

In an embodiment, the energy module further comprises a solar cell, such that the energy for powering the handlebar localisation grip is generated in a sustainable fashion. The solar cell may advantageously be arranged on the outer edge of the handlebar grip, where the lighting conditions are sufficient. The solar cell may be configured to power the modules directly. In an alternative embodiment, the solar cell is combined a battery. The latter may be advantageous as redundancy is provided this way. Additionally, a combination of a solar cell and a battery may offer the possibility to charge the battery with electricity generated by the solar cell, such that the battery lifetime may be increased.

In an embodiment, the handlebar localisation grip is further configured to process turn indication commands from the external device. In this embodiment, the communication module is further configured to receive a wireless turn indication command from the external device, and the control module is further configured to activate the first signalling module to provide a first turn indication signal upon receipt of a turn indication command by the communication module, wherein the first turn indication signal is an optical turn indication signal. This way, the user could plan a route to a certain destination on the external device. The external device then issues turn indication commands while driving the vehicle, while the handlebar localisation grip is used as a navigation means. For this, the first signalling module could be configured to provide turn indication signals, e.g. light signals through the at least one light emitting element of the first signalling module. Consequently, the colour of the light emitted by the first signalling module upon receipt of a turn indication command would be similar to the colour upon receipt of a localisation command. Alternatively, the colour of the light could be different for the two types of commands. This could, for example be achieved if the at least one light emitting element comprises a fixture with two light bulbs, two different LED elements, an RGB-type LED element or a light bulb with at least two filaments.

In an embodiment, the brightness and/or the colour of the light emitted by the at least one light emitting element upon receipt of a turn indication command may be adjusted by a user of the device. In this embodiment, the control module may be configured to control one or more properties of the light emitted by the first signalling module upon receipt of a turn indication command, such as the wavelength or brightness.

In an embodiment, the properties of activations of the first signalling module with the control module, upon receipt of a turn indication command by the communication module, can be customized by a user. In such an embodiment, the first signalling module may be configured to emit a flashing optical localisation signal, and the control module may be configured to control an amount of flashes, a duration of respective flashes and a duration of pauses in between the respective flashes by subsequent activation and deactivation of the first signalling module. Having adjustable light and activation properties may be advantageous for personalisation of the turn indication signal, which could provide additional differences between the turn indication and localisation signals.

In an embodiment, the at least one light emitting element could be configured to emit substantially orange light upon receipt of a turn indication command, in accordance with the legal standards for turn indicators.

In an embodiment, two handlebar localisation grips are provided on the two respective outer ends of a handlebar of a vehicle, for example a left handlebar localisation grip on a left outer end of a handlebar and a right handlebar localisation grip on a right outer end of the same handlebar. This way, the two handlebar localisation grips could be used for automatic turn indication of the vehicle, towards both the respective left and right sides of the vehicle.

In an embodiment, the handlebar localisation grip further comprises a second signalling module, which is connected to the control module and configured to provide a second turn indication signal. In this embodiment, the control module is further configured to activate the second signalling module to provide the second turn indication signal upon receipt of a wireless turn indication command by the communication module. This second signalisation module could be configured to provide a signal through different means of signalisation than the first signalisation module, such as vibrations or sounds. Having different signalisation means could be advantageous for the safety of the handlebar localisation grip, as sounds or vibrations do not require visual attention of a user, such that the user can focus attention on the surrounding traffic.

In an embodiment, the second signalling module comprises a vibration motor. This way, a haptic signal, such as a vibration, could be generated by the second signalling module.

In an alternative or additional embodiment, the second signalling module comprises an acoustic element, such as a speaker or piezo element. This way, an acoustic signal, such as a beep, sound or spoken instruction, could be generated by the second signalling module.

In an embodiment, the handlebar localisation grip comprises an input module, connected to at least the control module, wherein the input module is configured to receive input commands from a user to control the handlebar localisation grip and/or the external device, and wherein the control module is configured to further process the input commands and to forward the commands to at least one of the first signalling module, the communication module or the second signalling module. For example, the input module may be configured to control specific functions of the external device, such as navigation or music, preferably to control at least the sound volume of said functions.

The input module may comprise means to receive tactile input commands, for example comprise an electronic touch pad, a button or a switch element.

In a further or alternative embodiment, the input module is configured to receive voice input commands from a user, such as spoken instructions to control the handlebar localisation grip and/or the external device. The input module may comprise recording means, such as a microphone, to receive such voice input commands. In an embodiment, the input module comprises an input ring element that is movable with respect to the handlebar grip with at least one degree of freedom in order to receive input commands from a user. The input ring element could, for example be mounted laterally adjacent to an outer end of the handlebar grip, wherein the input ring element is displaceable relative to the handlebar grip, and wherein the input ring element is configured to be rotated around the longitudinal axis of the handlebar grip in order to select or issue certain commands.

In an advantageous embodiment, the input ring element is configured to be rotated around the longitudinal axis of the handlebar grip in discrete steps, similar to the scroll wheel of a computer mouse. This could, for example be achieved by having a snap element mounted on the ring element, or a built-in ratchet mechanism. Having discrete steps would improve the controllability of the input ring element by providing direct haptic feedback to the user.

In an embodiment, at least a portion of the input ring element is further configured to move in at least one additional degree of freedom. For example, a portion of the ring element could further be configured to be moved in a direction parallel to and/or perpendicular to the longitudinal axis of the handlebar grip. This way, multiple types of input commands could be issued by the user from one input ring element.

In an embodiment, the geolocation module is configured to provide geolocation coordinates of the handlebar localisation grip using a global navigation satellite system, such as GPS, Galileo, GLONASS, IRNSS or BDS.

According to a further aspect of the present invention, a vehicle is provided, comprising

- a handlebar, configured to steer the vehicle,

- at least one handlebar localisation grip as described above, wherein the handlebar localisation grip is mounted on the handlebar.

This vehicle may for example be a bicycle, a moped, a scooter, a motorbike, but also be a vehicle for people with reduced mobility, such as mobility scooters, rollators and wheelchairs. The handlebar localisation grip may be particularly advantageous for rental vehicles, shared vehicles and courtesy vehicles that are temporarily provided to different users

With the vehicle comprising at least one handlebar localisation grip is provided, the vehicle may be localised by means of the device. When at least two handlebar localisation grips are provided, for example at least one left handlebar localisation grip on a left outer end of a handlebar and at least one right handlebar localisation grip on a right outer end of the same handlebar, the vehicle may be configured to automatically provide turn indication signals, towards both the respective left and right sides of the vehicle. Additionally, the at least two handlebar localisation grips may be used for providing navigation instructions to the user of the vehicle.

According to a further aspect, the present invention further provides a vehicle localisation assembly, comprising:

- a vehicle as described above or a handlebar localisation grip as described above,

- an external device, configured to receive and/or send the wireless commands from/to the communication module, wherein the external device is configured to receive and/or send the wireless commands to the communication module via a wireless connection. Using this assembly, a localisation command may be send from an external device by a user in order to localise a vehicle or a vehicle localisation device.

In an embodiment of the vehicle localisation assembly, the external device comprises a fleet management system, which is configured to receive geolocation coordinates of at least one handlebar localisation grip according to any of the claims 1-19, and to store the received geolocation coordinates from the respective handlebar localisation grip at a remote location from the vehicle.

The fleet management system may provide for localisation functionality of a large fleet of vehicles provided with handlebar localisation grips, for example by activating vehicle localisation signals and/or for displaying geolocation coordinates. As such, the handlebar localisation grip may be particularly advantageous for monitoring positions of rental vehicles, shared vehicles and courtesy vehicles that are temporarily provided to different users.

The present invention further provides a method to localise a vehicle, comprising of the following steps:

- sending a wireless localisation command from an external device to a communication module of a handlebar localisation grip,

- receiving the wireless localisation command with the communication module, - processing the wireless localisation command in a control module of the handlebar localisation grip,

- sending geolocation coordinates to the external device, and

- activating a first signalling module of the handlebar localisation grip with the control module to provide a vehicle localisation signal.

This method could, for example be used for easy localisation of the vehicle in a large parking garage or bicycle shed. This method may provide for the same advantages as described above in relation to the handlebar localisation grip.

The present invention also provides a method to provide localisation functionality to a vehicle with a handlebar, comprising the steps of:

- removing at least one conventional handlebar grip from an outer end of the handlebar, if any, and

- mounting at least one handlebar localisation grip on the respective outer end of the handlebar.

Using this method, any vehicle with a handlebar can be retrofitted with a handlebar localisation grip. For example, a vehicle with a handlebar could normally have been fitted with conventional handlebar grips. Conventional as used herein means all handlebar grips that are known in the state of the art prior on the application date of current invention. By removal of at least one conventional handlebar grip, a free outer end is created at the location where the conventional handlebar grip was. The handlebar localisation grip is mounted on this outer end as its dimensions are configured to correspond with the dimensions of a conventional handlebar grip. The handlebar localisation grip may function stand-alone from the vehicle. Apart from the mechanical attachment, the handlebar localisation grip does not require any wiring or electrical integration in the vehicle. As such, localisation functionality is provided to the vehicle easily.

The vehicle may also comprise two conventional handlebar grips. By repeating the method for both handlebar grips, thus by removal of both conventional handlebar grips from the handlebar, two free outer ends are provided on the handlebar at the respective locations of the conventional handlebar grips. A single respective handlebar localisation grip will be mounted each respective outer end of the handlebar. As such, in addition to localisation functionality, the vehicle may also be provided with automatic turn indication and/or navigation functionality.

Further characteristics and advantages of the invention will now be elucidated by a description of embodiments of the invention, with reference to the accompanying drawings, in which: Figure 1a schematically depicts a portion of an embodiment of a vehicle localisation assembly according to the invention,

Figure 1b schematically depicts a detailed view of an encircled section ST from figure 1a, depicting a portion of a handlebar and an embodiment of the handlebar localisation grip according to the invention, seen in perspective view,

Figure 3b schematically depicts a side view of lateral cross section B-B of the handlebar localisation grip from figure 2, along plane B in figure 2,

Figure 4 schematically depicts an overview of the modules comprised in the embodiment of the handlebar localisation grip from figure 2.

Throughout the figures, the same reference numerals are used to refer to corresponding components or to components, which have a corresponding function.

Figure 1a schematically depicts an embodiment of a vehicle localisation assembly denoted by reference numeral 100. The vehicle localisation assembly 100 is configured to allow for localisation of a vehicle 200 by sending a wireless localisation command from an external device 300 to a communication module comprised in an handlebar localisation grip 1 that is mounted on a handlebar 201 of the vehicle 200.

In figure 1b, a side view of the encircled section ST from figure 1a is displayed with more detail. The handlebar localisation grip 1 is mounted on an outer end of the handlebar 201 of the vehicle 200. The handlebar localisation grip 1 comprises a handlebar grip 2, which is arranged on the outer end handlebar 201 by means of an inner sleeve inside the handlebar grip 2.

In the current embodiment, the handlebar localisation grip 1 further comprises a first signalling module 3, which is a ring-shaped LED-array that is arranged next to an outer end of the handlebar grip 2.

The handlebar localisation grip 1 further comprises a communication module 4, that is configured to send and/or receive wireless commands, such as the localisation command that is sent by the external device 300, and a control module 5, connected to the communication module 4 and the first signalling module 3, and configured to activate the first signalling module 3 to provide the vehicle localisation signal upon receipt of a localisation command by the communication module 4. The current embodiment further comprises an input module 9, which is configured as an input ring element that is mounted laterally adjacent to an inner end of the handlebar grip 2, and wherein the input ring element 9 is configured to be moved with respect to the handlebar grip 2 by means of rotation around the handlebar 201. The input module 9 is configured to receive input commands from a user to control the handlebar localisation grip 1 and/or the external device 300 by means of movement of the ring element.

The current embodiment further comprises a coupling module 6 being an NFC device. When an external device 300, that has not sent and/or received commands to/from the communication module 4, is held in the vicinity of coupling module 6, for example within 0,5 m, preferably within 0,2 m, the coupling module 6 initiates a connection with a second NFC device comprised in the external device 300. After performing a verification procedure, for example by providing a password on the external device 300, or providing input commands through the input module 9, a wireless connection will be established between the external device 300 and communication module 4.

The current embodiment comprises an energy module 7, comprising a solar cell that is mounted on the outer surface of the handlebar grip 2, such that it may receive sunlight to generate energy to power the handlebar localisation grip 1.

The handlebar localisation grip 1 according to the current embodiment also comprises a second signalling module 8, which is a ring-shaped LED-array that is arranged on an outer end of the handlebar grip 2, next to the first signalling module 3.

In figure 2, a longitudinal cross section of a different embodiment of the handlebar localisation grip 1 is displayed in more detail. Figure 3a schematically depicts a side view of lateral cross section A-A of the embodiment of figure 2, along plane A in figure 2. Figure 3b schematically depicts a side view of lateral cross section B-B of the embodiment of figure 2, along plane B in figure 2. Figure 4 schematically depicts an overview of the functional modules comprised in the embodiment of the handlebar localisation grip from figures 2 and 3.

The handlebar localisation grip 1 in the embodiment of figures 2 - 4 is mounted on an outer end of handlebar 201 , which comprises a circular cross section. The handlebar grip 2 is provided with an inner sleeve 12 along a central longitudinal axis 11 of the handlebar localisation grip 1. In this embodiment, the central longitudinal axis 11 of the handlebar grip 2 may be equal to the central longitudinal axis of the outer end of the handlebar 201. In this embodiment, the inner sleeve 12 extends through a portion of the interior of the handlebar grip and may accommodate a portion of a handlebar 201. The sleeve 12 is provided with a circular cross-section with a diameter slightly larger than the diameter of the outer end of the handlebar 201. The handlebar localisation grip 1 is provided with a first aperture on the lower side of the handlebar grip 2, that extends from the outside of the handlebar grip 2 into the inner sleeve 12. The first aperture is provided with a thread, such that screw 14 can be drawn into the first aperture. The screw 14 has sufficient length such that it may extend from the first aperture into the sleeve 12 on the inner side of the handlebar grip 2. If drawn into the first aperture with sufficient depth, the screw 14 may come in contact with the handlebar 201 , thereby causing a friction force between the screw 14 and the handlebar 201 which avoids removal of the handlebar localisation grip 1 from the handlebar 201 by means of force locking. As an alternative, a second aperture may be provided in the handlebar 201, arranged on a position that corresponds with the position of the first aperture in the handlebar grip 2, such that the screw 14 might extend from the first aperture through the sleeve 12 into the second aperture in the handlebar 201, thereby preventing removal of the handlebar localisation grip by means of shape locking.

In the embodiment of figures 2 - 4, a first signalling module 3 is comprised near the outer end of the handlebar grip 2. The first signalling module 3 comprises a transparent ring- shaped element 31 and two light-emitting elements 32, which are embodied as LEDs. The ring-shaped element 31 is made of a translucent material that scatters a portion of the light coming from the light-emitting elements 32, such that it appears that the light coming from the light-emitting elements 32 is emitted by the ring-shaped element 31.

On an outer end of the handlebar grip 2, an energy module 7 is arranged, comprising a battery housing that is configured to receive button cell batteries. Adjacent to the opposing inner end of handlebar grip 2, an input module 9 is arranged. The input module 9 comprises a ring element 92 that is configured to be rotated around the central longitudinal axis 11. The sleeve 12 extends through the input module 9 in order to facilitate mounting on handlebar 201.

In the current embodiment, the input module 9 further comprises at least two ferromagnetic position markers 94 spaced around the sleeve at constant distances, and an inductive position sensor 91. When rotating the input ring 9 around the central longitudinal axis 11, the position markers 94 move with respect to position sensor 91, therewith causing an electric signal that is forwarded to a control module via a connection wire 93.

The current embodiment further comprises an integrated circuit on a printed-circuit board 13, as displayed schematically in figure 4. On the printed circuit board 13, a communication module 4, a control module 5, a second signalling module 8 and a geolocation module 10 are arranged. A communication module 4, a coupling module 6, the second signalling module 8 and a geolocation module 10 are electrically connected to a control module 5 on the printed circuit board 13.

In the current embodiment, the electrical contacts of the light-emitting elements 301 of the first signalling module 3 and the electrical contacts of the energy module 7 are connected to the control module 5 on the printed circuit board 13 by means of soldered contact plates. The position sensor 91 of the input module 9 is connected to the control module 5 on the printed circuit board 13 by means of the connection wire 93.
