Detailed description

The present invention relates to a device composed as fig (1) from a touch display, a speaker, a memory, a GPS, a compass and a microcontroller, the memory is used to save the electronic map, tracks and coordinates of the locations, this device is installed in the car to control the loads by touch, these loads are: lights, signal, siren and air-condition, radio, and other loads, and each load has an icon on the display that is touched to on or off this load, because the display is small and does not accommodate icons for all loads, several procedures have been taken to accommodate all loads and display their states, the first procedure is that removing from display the icons of the loads that its controlling is not suitable for the current car condition, say, if the car is moving on the road, it’s no good to control the cap, trunk, fuel tank cover, so their icons should be disappear , and if the engine is turned off, the icon in the air conditioner and the signals disappear, as there is no meaning to their operation while the engine is off, The second procedure is to switch the display from one job to another, or to another display, there are several displays: the driving display, the passenger display, the guiding services display, and the car faults and problems display, and by touching one of the corners of the display, it convert from one display to another, the faults and problems Display appears automatically when a malfunction or a problem occurs, however, it can be accessed to know the quality of its parts as it will come later. As for the driving display, it is possible to control the lights, signals, siren, interlock, cab, trunk, driver seat, and fuel tank cover, and since the serine has its importance, it has not icon while driving, it can be operated by scanning anywhere on the display as long as the car is moving in the road, it can be launched from any display and not only from the driving display, and so that it does not start by mistake, the touch is not sufficient to run it, but it must be scanned a distance of no less than a certain value, and its working time is fixed regardless about the scanning time or scanning distance, from the passenger display, it is possible to control the air conditioner, the fan, the radio, the CD player, open and close windows and the cabinet lamp, and all loads that there is no problem with the passenger’s control, and when requesting to operate the air conditioner, the windows close and the fan works automatically, then the air conditioner turns on, after that, the icon for opening and closing windows and the icon for turning on and off the fan will disappear, and it will not appear again until after the air conditioner has been turned off. When driving, the driving display appears all the time, and the passenger display, services display, and problems and faults display only appear by request or by necessity, and their appearance is temporary, so that if a certain time passes without touching, it turns to the driving display.

Services related to the electronic map and GPS The device provides services related to the electronic map and GPS, and the device requests updating the map if a certain time has passed without updating it, and the map can be updated by connecting it to the computer via a USB connection, and it has information that needed to the driver and the device deals with it, such as The name of the street and the degree of its priority, and the maximum speed of the street, or the class to which this car belongs, this street is double or individual, and two directions or one direction and the direction of it, and whether there are intersections or traffic signals and their names and distances, and are pedestrians allowed to walk in this street or cross it, and the places of workshops and fuel stations, and important places, The device uses this information to issue messages, whether warning or guidance, in the appropriate place and time, and this is an a list of these services:

Warning services as the car previously had two distance meters, one counting since the car was produced and the other counting since the oil was changed, in this invention the oil distance meter was modified so that it is descending, when changing the oil a certain place in the display should be touched by the driver for several seconds to start the counter from the prescribed distance, after which the oil should be changed, also the prescribed distance can be changed and stored in the device's memory, and there is no need to set it every time, and the counter begins to decrease after the oil is changed, and it gives a message to change the oil when it reaches zero or shortly before it, and the message is accompanied In the name and location of the nearest oil change workshop, in this invention a third distance meter was added with the aim of giving an alert after a certain distance has been determined, and measuring the distance between two points, by touching its icon on the display at the first point, and touching the same icon at the second point, When the car approaches the intersection that without signal, it warns and draws the intersection in its correct direction and indicates the priorities of the intersection streets in colors, and mentions its names, and the location of the car, and displays warning messages in the display, and its display is according to the forms used in the traffic system previously, And warn when near to pump or drilling or street turnover, or pedestrian crossing point, a checkpoint, or a narrow road, or anything that dangerous on the road that needs to draw the driver's attention, and that is accompanied if necessary on a display of the situation, written text or voice message, If the exceeding is forbidden and the car device feels a sudden decrease in speed compared to the speed of the road in preparation for exceeding, it gives a message that warns of exceeding, the car device makes comparison between the car speed and the maximum speed of the street that it received from the map and gives a message that warns if high speed, and it also gives a message if very high speed if it find it, a message will warn against going in the opposite direction If it discovers this from the comparison between the direction of the car that he deduced from the compass and the direction of the street that it deduced from the map, and gives a red color to the street, and a message that warns of cutting the signal if the driver accepts the signal at a high speed, and a message warns against entering the prohibited places when the car is on its way to it, And a message calling for exiting the prohibited places if it was discovered that the driver entered it, and a warning message when the driver gives a right signal while turning to the right is prohibited, as well as if a signal is given to the left while turning to the left is forbidden, and if the car stops in a place where it is no parking, it issues a warning message of “no parking”, when the option of parking is activated, it explains whether this street is permitted to parking, forbidden or strictly prohibited, and if it is permitted is it longitudinal or altitudinal, and is it in exchange or free of charge, if it is not permitted it guide the driver to the nearest public parking area, the single road with two directions takes two colors in the display, green color for the right side, yellow color for the left side, and the device gives a warning message if the driver continue to drive in the left side of the road, and before the car reaches a curved part of the road with a certain distance, the device runs the car signal inside the car without turning on the external signal bulbs, it draw it in the display with a shape that similar to the form of curvature and its direction, the car device do that before the curvature by some distance, this distance increases with increasing the bending of the curvature and increases with car speed, and speaker broadcast a suitable sound or phrase expressing that.

Guidance services: Guidance services are on request, so the driver can request to broadcast the names of streets intersections, squares, exits and important signs that passes through it shortly before arriving at each of them, and the driver can choose specific thing to make the device broadcasts it when approaching it or accessing it, and it can also that the device broadcast the remaining distance on this thing every specific distance, the car device can guide to the desired destination, The guidance to the destination has several methods, the driver chooses what suitable for him, the first method is to make the device mentions the district name or region name in which this destination is located, and mention the name of the street that is close to it or which it is located in, and mentions an important mark close to it, and draws an arrow that begins with the mark and ends with the destination, the second method is that once the car enter a street within the track, the device asks the driver to continue in it until a certain mark and mention this mark, then exit the street right or left, and shortly before the driver reaches the mentioned mark, the device reminds the driver to exit from the current street and mention right or left and mention the street that he will enter, The third method is to give a summary of the trip before starting it, this is by mentioning the street names and turning points, the fourth method is to draw a mini map in which an arrow appears It starts from where it is currently and It ends with the required destination, The device can guide to the nearest main street, the nearest road, the nearest commercial area, the nearest market, the nearest city, the nearest district, the nearest railway station, the nearest amusement park, the nearest civil defense, the nearest workshop, and the nearest hospital... etc, the driver can request one of these things, the device displays the closest set of the required thing arranged according to the distance, and the driver chooses what is appropriate to make the device guide to it, and the device saves the tracks upon request and gives it a name, so that the driver can re-drive in it, and then the device records the names of the streets and their exit points in order, also the driver can request to save the place and give it a name, in order to return to it, at which point the device saves its coordinates.

Saving the tracks automatically: The tracks in which the car is traveling are automatically saved without the driver requesting and without giving them names, and classifying them into a rare and usual very usual, The rare track is the track in which the driver does not travel except rarely, and the date of the last time he derived in this track is automatically saved, but the usual track is the track that the driver usually used to drive in, and the very usual is the track that the driver is going on almost daily, if the driver did not use the usual track for a long time, it automatically turns into a rare track, while driving the device reminds the driver that he must turn left or right long enough before the rotation place by running the car signal inside the car without running the external signal bulbs, but only a sound in the speaker and draws in the display the intersection before reaching it with a sufficient time giving all streets in the intersection a specific color, and the expected street another color, and shows a comparison between the priority of each of them, and mention if some of the streets of the intersection is prohibited to enter, and also reminded him if he reached the end of the track.

As for preserving rare tracks, it facilitates restoring access to the destinations that rarely go to and ending these tracks, The driver can request to display rare tracks branching from his current location, and then he can request to complete any track he chooses from them so the device complete it tell its destination, and then he can request to go to that destination, and suppose that the driver has gone from a long time to a specific destination and wants to re-go to it, and he has forgotten its name, location and track to it, but it only remembers a part of the track, then he must go to that part, then choose " Show rare tracks " option, now the driver sees the rare tracks from the current place with their dates, touches the display on the track that he thinks is the desired track, then the rest of the track is drawn, suppose that this is not the needed one, touching another track , can now choose to go using this route, and the device will guide him to the destination.

Welcome message and farewell message: By request, the device can launch a welcome message, it is at the time of turning on the engine, it welcome the driver and ask him for a belt tightening, broadcast the audio clock and mention the time that passed while parking and the current direction of the car, and if he had traveled a long distance before this park it ask him to check the engine oil, the radiator water, and the pressure of the tires. Also, the driver can request the farewell message, which is a message broadcasted when the car is turned off, and the device asks to relax the seat belt, take precious things and close the windows and doors well, and remember the location of the car or register it, and broadcasts the audio clock and the current car direction, and wishes the driver good luck.

Display faults and problems of the car: It appears automatically when a malfunction or problem occurs in the car, and it can be accessed manually to know the quality of the car parts, knowing the fuel level and how much distance is left for the motor oil to be changed, and the car device is connected with the various sensors to deal with it: the car speed and the engine speed Engine temperature, fuel level, battery charging status, oil level, safety belt, sensation of the car key, also connected with shutdown sensors: doors, window glass, car trunk, fuel tank cover, canopy, and cab. Is this things are closed or not, and if some analog output is coming from the sensor such as the temperature and fuel level in the tank, the device convert it to digital to deal with it, and a warning is issued when there is a problem with the mentioned things, and if the matter is with the warning a voice message, and the intensity of this sound is proportional with the size of the problem and the sound intensity increases if the windows Open, the device write in the display the steps to be taken regarding this problem, and the location and name of the nearest workshop concerned with this problem, and this is a presentation of the problems: high engine speed, near the end of fuel, battery charging stops, engine overheating, low oil level, request to change the oil after the set distance , The air conditioner does not work, safety belt not tied, one door still open, fuel tank cap open, trunk open, car key unencrypted or with incorrect code, and others.

Self-tests When placing the car key in its position and before starting the engine, the device make sure that the key has the correct code, and a warning message will be issued if it appears otherwise and not allow the engine to start, then test the fuel level and battery voltage, and warn if there is a problem with these things, and when starting the engine, it is testing the battery voltage, fuel flow and high voltage, and warns if there is a problem with these things, and if the engine fails to start, the device displays in the display the possible causes of the failure of the starting, and if the engine work it gives a message that the engine is working, and ask the driver to fasten the safety belt if it is not fastened, and tests the shutdown sensors, and ask to close the open objects, and ask to go to the fuel station if the fuel level is low. After the car has moved, the icon appears in the display and the driver can touch it to close the center lock, after a short time it is closed and the icon disappears.

The shape of the car signal in the display It is possible through the settings to determine whether the car signal shape is conventional, or its shape is similar to the intersection that the car passes, and in the case if it is similar to the shape of the intersection then the shape shows the intersection so that the driver sees all the streets of the intersection with a certain color and another color for the street to walk in if the driver has requested guidance to a specific destination, or it is expected to drive in it if the driver usually drive in it, and the signal sound is automatically triggered internally to remind the driver without being turns on the external signal bulbs, The out sound has a certain tone indicating that it was played automatically, and it turns into the normal tone when the driver manually runs the signal manually, and any direction of rotation is forbidden, it takes the red color in the signal mark, and if the intersection is free from the signal, the driver sees a comparison between the priority of the intersection streets In colors, but if it has a signal, the device announces that it has a signal.
