[0001] This invention is related to a method and system of current positioning, control and management of the driving speed of a go-kart (go-karting, go-carts, karting) on a go-kart track. It can find its application in the field of organizing entertainment, recreational and/or sports services on go-kart tracks, while conducting training sessions and go-kart courses, etc.

BACKGROUND OF THE INVENTION

[0002] Go-kart or Go-cart racing or karting (gasoline or electric) rental business for leisure purposes is a popular activity worldwide.

[0003] Various karting designs are known; their most common construction is a small, four- wheeled vehicle powered by an internal combustion engine or an electric motor.. Most models have one seat - for the driver (only), but there are other models where a . driver and a passenger can be accommodated. As a rule, karts are driven in specially designed karting tracks; having different in type and nature situations occurring while racing, and these situations must be reliably controlled or avoided, mainly in order to ensure the safety of users of karting services, marshals, and safety facilities surrounding the karting tracks.

[0004] Most often, such situations occur as a result of a variety of reasons but mainly due to the fact customers are unfamiliar - in most cases - to karting machines offered in terms of their technical capabilities of speeding (speed accelerating). In addition, such situations occur due to the drivers’ lack of experience who are unable to properly consider the features of the kart track, the sequence of sharp turns and the high speed karts can increase when racing on straight sections. In this regard, it is necessary to create prerequisites for controlling the racing of the karts on the track. Therefore it is necessary to monitor the position of the kart on the track, as well as to make it possible to allow automatic adjustment, reduction, limitation of the speed of the go-kart racing by manual, automatic and remote-control system (including) so as to reduce the chances of occurrence of risky situations arising from inexperienced go-kart driving or for any other reasons.

[0005] EP3385890 Patent Publication has been disclosed; it describes a method and system of detecting and analyzing the effects of motor vehicle racing, in particular go-karts, as the latter— due to their conformation, properties and applications enhance the safety mechanisms and/or systems while racing on go-kart circuits (tracks). The system consists of three subsystems, comprising a set of technical devices located on [the base on] computer devices; by using them, a physical contact between two racing (moving) karts can be detected, vehicles can be identified, their location on the track - of approximate accuracy - and when an impact or physical contact with another vehicle can be determined. This information can be transmitted - using a specific software - to a management and storage computer program, and connect it to an image recording system mounted on the race track; data is captured (collected) and transmitted by the car/kart itself. The goal is to immediately detect any contact or collision between two vehicles, especially karts, occurring during a race, identification of these karts - each associated with a unique identification number, unmistakable identification of when and, optionally, where the impact/contact has occurred. By collecting all the reference data, the same is sent from the same kart to the receiving modem, so that this information is processed and managed by a computer program and subsequently processed by a software that can connect it to the recordings of images captured by the video cameras usually installed in the track circuit by analyzing the images in the moments before and after finding the impact - in order to determine its nature. In this manner, it is possible to have sufficient data to manage all incidents occurring on the track, to correct mistakes made, as well as to impose a penalty on the behavior of pilots, etc., and last but not least to have no doubt as to the accuracy of the data collected to be used by the track judges or the pilot’s coach - in case of a training session. The first subsystem consists of an electronic device that basically has one or more sensors mounted in the bumpers or other points of any vehicle/kart and it detects collisions, contacts or impacts that vehicle/kart may encounter during a race. The sensors mentioned are of the type that reacts to physical contact between two vehicles and are connected to a control box integrated with the data collection means of the aforementioned sensors and which allow connection via a transmission module to the second subsystem, and all of which is controlled by a microcontroller. In addition, a means of preventing impact, preferably a proximity sensor, is provided operating through a wave emitter that sends a signal to the control center upon a collision with another go-kart. This type of sensor is functional and is intended to avoid contact or collision. This device may include a GPS module or chip in order to determine the position on the track where the impact has occurred and therefore there is data for a quick access to the camera covering that area of the track; data integrated into a package sent to the second subsystem. In any case, the said electronic device has a unique identifier unmistakably linked to the vehicle number (circuit board) it is installed in. Every time this electronic device detects, through the sensor or respective sensors, contact with another go-kart or an obstacle, it sends - using its transmitter module, a wireless signal to the second subsystem. This signal contains its unique identification code and additionally the GPS coordinates of the location of the vehicle. The described method and system have the primary task of collecting data and analyzing them after processing them, without providing technical opportunities to undertake actions to prevent an accident both for the first racing go-kart and for others racing behind it.

[0006] A known patent publication presents a method and system of controlling go-kart speed (US 2011307133A1), in particular a method and system of automatically balancing acceleration rates and electric karting speed(s) of based on the driver’s weight and other characteristics of his. When a user is logged in, their data is assigned to a specific go-kart, connected via a remote radio system to a kart controller, set/tuned to allow“normal speed” of racing, defined at least in part by the entered driver’s weight data. The go-kart track speed control: method allows the user to have a suitable go-kart assigned (i. e. of a suitable small, medium or large seat) based on the weight information.

[0007] The system provides for each go-kart to be provided with a unique frequency transponder, controlled by a radio frequency (RF) transmitter. The remote transmitter may change the speed settings, including the acceleration speed (or the speed at which power or amperage is delivered to the engine), to the electric motor controller of each kart on the track before, after, and during racing on the track, e. g. during competitions. The system automatically programs the go-kart electric motor controller to different settings to match acceleration rates and speeds for the different weight of drivers. Engine speed and acceleration rate of each go-kart are adjusted based on the driver’s weight so that the actual acceleration speeds and the maximum go-kart speed in the race are comparable. According to the invention, each -driver is issued a magnetic stripe card and it contains, but is not limited to, information on the balance of the driver's account, the driver’s level of experience and the driver’s weight. Another information not related to speed control may also be included in the driver's license card. The information, including the driver's weight, is read from the driver's license card and used to adjust the speed and acceleration rate of the go-kart electric motor operated by that participant. The card can be read at the point of sale (POS) (i. e. a cashier or a check-in desk) or using a card reader mounted on each go-kart. The go-kart "normal racing speed" is determined by the level of experience (e. g. novice, an open or a professional racer, although in other embodiments of the known system there may be more than or less than three levels). These speeds correlate with the calculated speed of the base engine required to reach that speed, based on the typical go-kart weight and the adopted standard driver weight.

[0008] The described method and system of go-kart speed control are of limited application, insofar as speed control is based on a combination of parameters - a driver's personal weight and level of experience. This method aims to match the speed of the go-karts using the driver’s weight data, thus creating equal levels of racing for the drivers, using the methodology described above. The method and system do not take into account the instantaneous positioning of each go- kart and its speed of racing, so it is not possible to control and manage the go-kart racing in the event of an emergency, for example, to timely submit a signal/alarm for a speed reduction for the purposes of preventing an emergency situation, as well as to reduce the racing speed of other go- karts racing after the one that may create such a situation.

[0009] A go-karting track positioning system is known, consisting of an "n" number of camcorders (video cameras) located at different points on the karting track connected to a central control panel of racing control on the karting track, each of these transmits a video signal from a certain interval of the track within the camera range. The cameras fare mounted and positioned/oriented so that there is an overlap of the peripheral sections of the track areas observed. Another system of positioning a track-racing go-kart is known and it consists of at least three "markers" located at different locations on the go-kart track, as well as markers mounted on each kart. Triangulation using radio signals emitted by the anchors and the markers ensures the location of a go- kart in a certain section of the track. [0010] There is a known system of submitting automatic commands of a go-kart that has not passed into the subsequent sector - within an expected time (sectors can be determined by marking devices and/or a timing detector located on the track. Revs/speed of all racing go-karts is automatically reduced in the sector the particular go-kart has entered last.

[0011] Systems of measuring revs/speed and application of a go-kart engine speed limiter are known using radio communication in order to set the limit of each go-kart racing on a go-kart track. A known go-kart speed control system (http://www.de-haardt.com) consists of a rev/speed limitation application device mounted fixedly on the kart and connected to the engine ignition system, such as the speed limitation device; it is powered by a charging coil installed in the go- kart engine. The speed control device is coupled to a sensor reading the pass, through the start- finish line. Different sections of the kart track have one or more marking devices determining the sectors where speed may be restricted.

[0012] The speed limitation application devices located on the go-karts and marking devices along the go-kart track are controlled by a hand-held remote control. The system operates by radio communication, signaling via the remote control towards the device of applying speed limitation to one or more karts in order to reduce the racing speed. The remote control can be used to signal/alarm the marking devices, thus limiting the racing sp eed in certain sections of the track. By using an optional extension extender device, the system can be connected to a computer and commands can be sent not only from the remote control device, but also from a computer - if it is technically possible.

[0013] In the system described, an operator (manual) intervention is used, where operators select the value of the limitation prior to the beginning of karting racing or while racing. The manual control of processes is associated with the subjective judgment of the operator, and may lead to a risk of human error respectively; in case of more than one incident at the same time - to the inability to quickly and properly respond to the situation. Setting limitations can be done using a portable push button device or a computer. The areas of operation of limiting the revs are determined by 'marking devices' delineating the areas yet not allowing the precise position of the go-kart on the go-kart track to be determined.

[0014] The main disadvantage of the described known karting track speed control and control systems is the insufficient control reliability with respect to the overall racing control of karting track go-karts, in particular insufficient - in bulk - information on the instantaneous/current positioning of the go-kart along the karting track, for example, there is no information about the exact position of the go-kart (it is known in which sector the kart is located, but not exactly in which part of the sector); in addition, there is no information about the racing speed of the individual karts, in order to provide the basic control indicator— go-kart safe racing, When using these systems, it is generally necessary to install additional devices along the entire length of the go-kart track.

When an accident occurs at the beginning of a sector, it is not possible to automatically undertake effective actions to ensure racing safety, as the system will not reduce or it shall limit the revs/speed of subsequent karts entering this sector too late. All currently known models operate on a radio signal basis.

[0015] There is no known unified system of go-kart positioning control during racing on the track and the possibility to undertake automated actions to limit revs/speed in certain cases on the basis of predetermined racing patterns.

SUMMARY OF THE INVENTION

[0016] Given the described level in technology in the described field, the scope of the invention is to provide a method and system of controlling and managing go-kart racing on a karting track by measuring the current positioning of the go-kart along the track as well as automatic speed control based on predefined scenarios and pilot racing models in order to provide increased racing safety on the go-kart track and reduce the possibility of risk situations occurring.

[0017] The task is solved by a method and system of controlling and managing the go-kart racing, as its essence is based on the simultaneous measurement/ determination of the go-kart location and speed - at any moment while racing on the track. The received positioning and speed data is transmitted to an electronic device connected to the go-kart engine, and it automatically submits - via a wireless connection to the driving software - and, if necessary, returns a command, and the electronic device limits the go-kart speed.

[0018] The task is solved by a method of go-kart racing control and driving, where after a go- kart starts racing, a device mounted on the go-kart transmits positioning: information along the go-kart track. [0019] According to the invention, after a go-kart starts racing on the track, the go-kart positioning and racing speed are simultaneously measured; the data is transmitted to a local server to be processed and a wireless signal is sent to a control electronic device mounted on each go-kart, in order to reduce engine revs and racing speed and speed of the racing go-karts along the track - down to a safe racing speed.

According to a preferred execution of the method, the go-kart positioning and speed measurement is performed by collecting information on the rotation; (revs) of the go-kart elements from a contact or contact-less element mounted on the go-kart rotating parts that sends a signal to the electronic device.

According to a variation execution of the method, the measurement of a go-kart positioning and racing speed is performed by directly collecting information on the revs of the rotating elements of the engine. .

According to another variation execution of the method, the positioning measurement of can be carried out by using a GPS technology or a combination of a GPS technology and collecting information on the revs of the go-kart rotating elements or the engine.

[0020] According to an exemplary execution of the method, when go-karts start racing on the track, positioning data, racing speed and acceleration and orientation in space data is transmitted to a local data server by all racing karts - data is processed and entered into predefined go-kart control models; if certain situations occur a signal is sent to the electronic device which limits the engine rev/speed.

[0021] According to a variation execution, for the purpose of improving the method of measuring current positioning, the length of a previous lap of a pilot is used in the current karting session.

[0022] According to another variation execution of the method of measuring current karting positioning, data on the achieved length of each completed lap (the distance traveled between two passings of the start-finish line) from all previous in previous karting sessions is used.

[0023] According to one variation execution of the go-kart driving and motion control method, the data in the local server represent pre-defined racing patterns defined by the combination of at least two criteria, for example the driver's experience and/or age. [0024] According to a preferred execution of the method, the pre-defmed models include limiting the engine speed during the entire track racing.

[0025] According to another execution of the method, the predetermined models include limiting the engine speed only in certain areas of the track - dangerous turns or sections where rev/speed limitation is activated.

[0026] According to another variation execution of the method, upon stopping or in case of collision of one or more go-karts at a certain point of the karting track, an engine speed reduction signal is automatically sent to the electronic device of each go-kart approaching the incident area and after passing the incident area, the engine speed limitation is restored to its previous normal operation mode.

[0027] The task is solved by a go-kart track racing/motion control and driving system consisting of an electronic rev/speed limitation device coupled to sensors which, by means of a driving software (called the "software" hereinafter), ensures reliable and safe go-karts racing of the track.

[0028] The go-kart racing control and monitoring system consists of an electronic device on limiting engine revs/speed mounted fixedly on each go-kart and connected to the ignition system of the engine.

[0029] According to the invention, the speed limiter device is configured as a positioning sensor mounted to a rotating element of the go-kart connected to a control electronic device mounted fixedly on the go-kart and connected to a local database server via a wireless connection model.

[0030] The control electronic device consists of three interconnected modules, a power- providing, control and“data” module, respectively, mounted in a waterproof housing.

[0031] The control module is configured as a separate plate and a processor, a go-kart engine speed limiter switch, and an acceleration sensor (an accelerometer), a rotation sensor (a gyroscope), magnetometer (a compass) are mounted and connected to each other in the space, as well as a GPS receiver and signal LEDs.

[0032] The "data" module is designed as a plate and an "n" number of contact elements connected to the electronic device where sensors are connected to are mounted. It is preferable to use sensors to collect and process telemetry data, for example a brake pedal pressure sensor, an accelerator pedal pressure sensor and a steering wheel system sensor. [0033] According to variation execution of the system, when the kart is electric, the speed limiter device is connected directly to the electric motor or to the controller run by it.

[0034] According to the invention, the go-kart driving and racing control method and system are distinguished by the completeness of the proposed technical solution, thus providing effective go-kart racing control along the entire length of the track, as well as go-kart traffic/racing management in case of emergencies, by automatically introducing racing speed limits of a go- kart approaching fully stopped go-karts, thus limiting the size of the occurred emergency situation. The objects of the invention (a method and a system) use a web-based application that provides complete control on the go-kart speed based on continuous measuring/calculating of the distance raced from the start and the racing speed; the data is being processed and enabled automatically - using the electronic device mounted on the go-kart to signal to limit the engine revs/speed.

[0035] The aforesaid web driving application has defined various conditions (situations) where accurate measurement of the current distance along the track- i. e. a go-kart has raced within a single lap - is performed. Also, the racing speed is measured using information obtained from the positioning sensor on the number of engine revs or the number of revs of rotating elements.

In this way, by accumulating data in the local server, a method of self-training of the positioning sensor is applied, forming a driver’s personal profile. In addition, predefined emergency and driving/racing models can be entered in the local server, whereby the electronic device of each go-kart shall be automatically signaled to limit engine speed in order to «reduce speed and ensure driving/racing safety. The application can also be used to send manual commands to the electronic device. By properly selecting the elements and positioning them on the kart, the system can determine - relatively quickly and reliably - the current position of the kart and the racing speed, and by combining this data with a variety of pre-defined situations and driving/racing models to send automatic commands in limiting revs/speed, thus providing a higher level of safety on the go-kart track.

[0036] The system is designed in a way it can provide complete management of the go-kart track activities, as it contains a complete database of user information, track features, by providing all the necessary sensors and antennas to submit continuous information; also, they allow its self- training. The system can monitor the racing of all karts on the track, while simultaneously determining the current positioning of each go-kart along the entire length of the track, and display it on the screen of the remote [control] of the track racing control. Based on current positioning information and the racing speed of each go-kart, the system gives automatic commands based on the occurrence of situations where forced speed limitation of the internal combustion engine or electric motors is required. The software also allows manual control of engine speed.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0038] An exemplary execution of the method and system of racing managing and controlling on a go-kart track is presented for the purpose of illustrating the invention, without limitation to the constituent elements described therein, and other technical elements and modules may be used that provide equivalent technical outcome and effectiveness of using the system scope of the invention. Therefore, it should be understood these drawings depict only an exemplary execution in accordance with the disclosure of the nature invention and should not be considered as limiting its scope. Later on, the system will be described in further detail by using the accompanying drawings.

[0039] In an exemplary execution of the invention, the method of managing and controlling the racing on a go-kart track is performed in the following sequence: the user, a go-kart pilot registers at the go-kart track at a Kiosk or Cash Desk (POS terminal) /Figure 1/, and then by entering personal and other data stored on a local server, their personal profile is created. The personal profile also stores data from the pilot’s previous racings on the track, for example, the measured length of each lap completed, representing the distance traveled between two passes at the start-finish line of the track. The user wishes to go karting by filling out an order that specifies the purchase of laps, minutes or packages. Based on the order created, in a web application used to manage the operations on the go-karting track, a go-kart session is created, with a duration equal to the duration of the purchased product, in combination with the chosen type of go-kart. This is followed by an installation and accommodation process, where the user’s personal profile is connected to the particular go-kart, thus creating a connection between the user and the managing electronic device mounted on the go-kart.

[0040] In addition, data such as, but not limited to, the calibrated base length of the track along the centerline, the maximum permissible engine revs, data determining the restriction levels of the engine revs in certain section of the track or such that require to be restricted/limited in case of certain situations occur are also entered in advance in the local go-kart database on managing a go-kart racing on a track.

[0041] If the local server has user’s data about a previous racing at the go-kart track, the determination of the current positioning is made on the basis of the average lap length of the particular user, and the data on the average length of one. lap is corrected after each lap completed in the current racing, too. Thus, the current positioning during each lap is determined by the average value of the length of the previous laps of the track by the same pilot.

[0042] According to a variation execution of the method, when a user does not have a registered profile or [shall] races a go-kart for the first time on this track, the operation to improve the current positioning determination is performed after the first lap, and for each-subsequent ones, the current positioning shall be determined by the length of the average values of the previous ones. The software analyzes the accumulated database of user’s laps, excludes the peak/top results, and calculates the distance traveled along the track with a higher degree of accuracy. Adjustments to the databases are made after the user’s each completed lap.

[0043] During racing/driving the go-kart, the positioning sensor transmits data about the current go-kart position at any time based on the data after self-training/adjustmen t tofthe driver’s style. At the same time, the elements located in the electronic device transmit information to the server and driving software on the current positioning and state of the go-kart, i. e. whether or not it is moving or has stopped, at what speed it is moving, etc. In case certain situations occur, the electronic device receives a command from the driving software to limit the engine revs by force, resulting in, regardless of the go-kart driver's actions, i. e. whether or not the driver continues to press the accelerator pedal of the go-kart, the racing speed is limited and reduced to a safe speed.

[0044] According to variation execution of the go-kart racing control and driving method, predefined driving patterns are introduced into the database server in advance - in order to be applied depending on a combination of different criteria, for example, driver’ s experience and/or age. Models may include limiting engine revs throughout the driving/racing on the go-kart track or limiting engine revs only at designated areas of the track. In the latter case, virtual track areas (dangerous turns or sections) are defined where revs are restricted. The restriction applies only when entering the designated area and is lifted after the go-kart leaves the area designated as dangerous for the particular driver. The positioning sensor works in combination with the driving software, and a self-study method is applied to each pilot's driving style. The method is based on the analysis of time from previous laps of drivers extracted from the database (drivers’ profiles) by comparing the data - average lap time, measured revolutions at the speedometer relative to the tire circumference. Processing of the collected data, excluding peak times, allows determining with greater accuracy the location of a particular go-kart driver along the track.

[0045] For greater precision, the positioning sensor works in combination with three other sensor devices housed in the electronic device - a GPS module (applicable only to outdoor go-kart tracks), a compass and a gyroscope, as well as an option of having te le metric sensors mounted to read brake and accelerator pedal data, etc.

[0046] The various sensors located in the electronic device transmit information to the local server, and after processing it, if necessary, it sends a signal for forcibly limiting the engine revs in order to reduce the speed of driving. The driving software has pre-entered data that determines the levels of engine rev limitation in certain sections of the track or in situations where limitation is required. In such a case, the electronic device signals to the software installed on the server via a Wi-Fi signal, and it returns a command to automatically reduce engine revs regardless of the go-kart driver actions, i. e. whether or not they continue to press the acceleration pedal of the go- kart.

[0047] According to another variation execution of the method, when one or more go-karts stop at a certain location on the go-kart track, the system will automatically reduce the engine revs of all go-karts approaching the accident zone. After passing the accident zone, the engine revs will return to normal mode of operation.

[0048] The method of racing/driving control on a go-kart track is done by means of a driving and speed control system of a go-kart, and it includes a go-kart 1 consisting of a supporting chassis 2 a seat 3 is mounted on. In addition, a motor/engine 4 is mounted on the chassis 2 connected to the rear motor axis 5. A control electronic device 6 is mounted at the rear of the seat 3, designed as a standalone module, connected to a positioning sensor 7 mounted on a rotating element of the go-kart 1.

[0049] In an exemplary execution, the electronic device 6 is placed in a housing, preferably waterproof, where three separate sub-modules - a power supply, control and data modules respectively, are located and connected.

[0050] Inside the power module, a power-providing element 8, preferably a single-cell lithium- ion battery, is mounted, coupled via an adapter for converting voltage 9· using the motor 4 of the go-kart 1.

The control sub-module is preferably configured as a separate circuit board, where a processor 10, a switch 11 for limiting the go-kart engine speed/revs, an acceleration sensor 12

(accelerometer), a rotation sensor 13 (a gyroscope), a magnetometer (a compass) in space 14, a GPS receiver 15, signal LEDs 16 designed to show the device status.

The control module is connected to the data module, also designed as a separate circuit board where mounted an "n" number of contact elements 17 are mounted on, associated with the electronic device 6 and sensors for various purposes are connected to, such as sensors for collecting and processing telemetry data, namely: brake pedal pressure' sensor, accelerator pedal pressure sensor and steering wheel sensor not shown in the figures, thus allowing it to monitor and determine its angular position. This data is necessary for the go-kart electronic control device 6 can submit to the local server up-to-date data on a driver’s style of driving, or form and self-train the positioning sensor 7 mounted to the rear axle 5 of the go-kart 1, respectively. [0051] According to a preferred execution of the system, when using an internal combustion engine go-kart 1, the electronic device 6 is connected via a cable connection 21 to a starting contact switch 22 to the ignition system of the go-kart engine 4 using the contact switch 22 , and it provides speed/rev measurement and application of speed limitation. The signal from the ignition system is a series of short high voltage impulses, one at each engine rev. In the particular case, in electronic device 6, these signals are converted to low voltage suitable for measurement by the microprocessor electronics in it. By measuring the interval between two impulses, the engine rotational speed (revolutions) is determined and if they exceed the speed limiter, the signal from the ignition system towards the mas (similar to the mechanical switch) is shortened by a semiconductor switch (transistor or triac), the same way the engine also stops igniting the fuel and cannot accelerate. The semiconductor switch 11 is processor-controlled and shortens the impulses only for a short time, which is calculated and determined by the software based on the limiter value and the current engine revs. By means of software control of the amount of stopped and allowed sparks, the "limiting" function is achieved and thus the engine cannot exceed the prescribed speed revs.

[0052] In cases where the go-kart 1 has an electric motor, the electronic device 6 is connected directly to the motor 23 or to the controller that controls it. For go-karts where the position of the accelerator pedal is connected to an analog sensor (a potentiometer) and. whose signal is processed by the motor controller, it is appropriate to use a variation execution where the signal from the sensor (input) is modified and is submitted (output) in a way as to follow the formula Output = min (Input, Limit). In this way, it is possible to effectively limit the course of the accelerator pedal to a certain limit, i. e. pressing it after this point shall have no effect.

[0053] In electric go-kart models, the ability to limit engine power is incorporated into the controller of the electric motor. The setting of the limiter is specific for each case, but in practice a cable is used: through it - using a digital signal - one of several pre-defined and recorded in the controller configuration settings on speed modes is selected. For this type of go-karts, it is possible to add a special module to the go-kart control device to coordinate the value of the limiter to one of the speed modes, and thus carry out the forced speed reduction.

[0054] A positioning sensor 7 is mounted on the rear motor axis 5 of the go-kart 1, connected to the electronic device 6 by means of a cable connection 24. [0055] Preferably, the positioning sensor 7 is configured as a standalone module consisting of a contact element, for example a magnet 25 and a sensor 26 connected to it. The magnet 25 is fixedly mounted to a rotating part of the go-kart 1 drive system, e.g. the rear axle 5 (tires, rims, belt, chain, etc.), and the sensor 26 is suitably mounted fixedly on a go-kart 1 element to take into account the movement of the magnet 25. Thus, at each turn of the driving part of the go-kart, for example the rear axle 5, the magnet 25 is positioned away from the sensor 26, thus closing the chain, and the electronic device 6 receives a signal for a complete turn/rev. A positioning sensor 7 is mounted on each go-kart 1 and can be used to determine the speed of travel as well as the distance traveled since it started on the track. The positioning sensor 7 calculates the distance traveled and the speed of travel based on counting the received signals of completed revs relative to a predetermined tire circumference and thus convert it to the distance traveled. The start-finish line of the go-kart track is taken as the starting and ending point for the distance traveled (in meters) - per lap.

[0056] The control electronic device 6 is connected via a wireless device, for example, a modem 27 to a local server 28 where a software module 29 is installed.

[0057] The go-kart track driving and control system operates as follows: after a go-kart 1 starts moving on the track, the positioning sensor 7 receives speed data and transmits it via the electronic device 6 to the local server 28, where more details are also provideo on the go-kart positioning on the track, distance traveled, speed. Upon detection of a specific event (collision, stopping, reversing, last lap, etc.) occurred, the server 28 automatically sends, via the wireless modem 27, a signal to the electronic device 6 for limiting the engine revs of go-kart 1. The electronic device 6 limits the revs by signal b depending on the engine type - one of internal combustion engine or an electric motor.

[0058] At the same time, the server 28 also signals to the electronic devices 6 of the go-karts that approach the area of a specific situation, thereby automatically limiting their speed of travel, preventing them from entering the incident zone in high speed.

Depending on the severity of the situation occurred, for example, several go-karts 1 have stopped along the track, the system will automatically signal to the electronic devices 6 of all the other go-karts on the track, shutting down their motors and this will ensure they are forced to stop (racing). Such impact can be ensured regardless of the positioning of the go-karts on the track or only in a specific area of the track, for example before the incident zone.

[0059] The system can control the driving speed of individual go-karts, for example by limiting the revs of a slower-moving go-kart reached by a faster-moving go-kart. In this way, regardless of the pilot's experience or their behavior on the track, conditions will be provided to facilitate the passing (overtaking) the slower-moving go-kart without provoking the occurrence of incident conditions. As soon as the overtaking is completed, the restriction imposed on the slower moving go-kart will be dropped and it may race at its previous speed.

[0060] Such driving speed control will also be applied if it is determined a go-kart has started going in a direction opposite to the defined driving direction: the system shall signal the electronic device 6 of the corresponding go-kart to turn its engine off, as well as a signal to limit the engine revs of the go-karts approaching the area where the stopped go-kart is located. The system may impose a forced restriction on the engine revs of a go-kart whose pilot drives in a dangerous/risky manner further endangering other racing go-karts.

[0061] After changing a specific condition (e.g., overtaking the incident location) occurred, the positioning sensor 7 transmits information to the device 6, and the latter communicates via a Wi- Fi signal 29 to the server 28, and it in turn sends a signal to the electronic device 6 to stop limiting the engine revs and restore the engine revs, allowing the previous mode of normal, permitted speed, respectively.
