- when connected to the dispatch center, conduct automatic data transfer (information about the current speed, location, parking time, status of the connected sensors) through the GPRS communication channel to the dispatch center dispatcher. The frequency of parcels may depend on: the state in which the navigation device for monitoring and controlling the technical condition of the vehicle is located (“movement” or “parking” mode); from the distance traveled (for example, every kilometer); from a change in course (when changing the angle of rotation by an amount exceeding a predetermined threshold value);

- ensuring the recording of the current location and speed of the user in the FLASH-memory in the absence of connection to the dispatch center.

The operating principle of the navigation device for monitoring and controlling the technical condition of the vehicle is based on the principle of determining the location of the vehicle using signals from space navigation communication systems, displaying the current location of the vehicle on an electronic map of the area, and receiving data packets via the GSM channel via GPRS from the data collection and transmission server about the current congestion of roads.

The principle of operation of the navigation device for monitoring and controlling the technical condition of the vehicle as a diagnostic device for the technical parameters of the vehicle is based on the analysis of information from sensors installed on the vehicle.

When the supply voltage from the power supply unit 5 is tested, the device is tested by the peripheral 6 and the main processors 7, and if the test passes successfully, the navigation receiver 10 is turned on. Then, the navigation signals from the spacecraft 16 of the navigation communication system are received by the antenna 14. In the navigation receiver 10, the reception transformation, signal processing of spacecraft 16 of the navigation communication system.

The results of solving the navigation problem — the navigation parameters (time, coordinates, ground speed vector) of the moving vehicle — are output to the first information inputs of the main and peripheral processors 6 and 7, respectively. At the same time, navigation signal reception modes are provided both from three space navigation communication systems (GPS, GLONASS, GALILEO), and only from any one navigation communication system at the request of the user. The choice of the mode of receiving navigation signals is set by selecting the corresponding item in the device settings menu using the keyboard of the block 22 with radio modules. The adopted navigation parameters from the information input / output of the peripheral processor 7 go to the information input / output of the GSM modem 11, to the high-frequency input of which a GSM antenna 15 is connected and then using the GPRS-exchange means 17, the Internet 18 these parameters are sent to the telematic server 19 , the Internet 18 and the PC 21 of the operator of the dispatch center, where the current location of the vehicle is displayed on an electronic map of the area.

In the absence of communication with the dispatch center, the navigation parameters from the information input / output of the peripheral processor 7 are sent to the information inputs / outputs of the FLASH memory 2 for storage, and when the connection with the dispatch center is resumed, the saved data from the FLASH memory 2 is transmitted via the GSM modem 12 to the dispatch operator center. Simultaneously with the delivery of navigation parameters to the second information input of the peripheral processor 7, information is received from the interface module 8, to the information inputs of which information is received from sensors and the on-board controller of the vehicle (not shown). The second information input / output of the peripheral processor 7 receives information from the inputs / outputs of the radio network controller 12, which is designed to control the unit 22 with the radio modules. If the technical parameters of the vehicle do not go beyond the specified limits, then information is not transmitted to the priority information input of the switch 4 of the LCD display 3. The main processor 6, when power is supplied, loads the working operating system and cartographic support from the information input / output of the FLASH memory 2. After loading the operating system and cartographic support, the navigation input from the navigation receiver 10 is received at the information input of the main processor 6. The received navigation parameters are processed by the main processor 6 and are displayed as a cursor on an electronic map of the area, which is loaded from FLASH-memory 2, and transmitted through GSM modem 11, means 17 for providing GPRS exchange to the server 19 for collecting and transmitting information about the current traffic congestion for analyzing the current speed of the vehicle in a particular area. At the same time, information from the GSM modem 11 is received at the first information input / output of the main processor 6, and information is received at the high-frequency input of which via the GSM antenna 15 using the means 17 of providing GPRS exchange, the Internet 18 and the server 19 for collecting and transmitting information about current traffic congestion about the loading of roads, which is used by the main processor 6 for optimal construction of the route of the vehicle to a given point on the route. From the information output of the main processor 6, information (electronic terrain map, marker of the current location of the vehicle) is fed to the information input of the switch 4 of the LCD display 3 and, if there is no information on the priority input of the switch 4 of the LCD display 3, it is transmitted to the input of the LCD display 3.

All data on the current traffic congestion from the information output of the GSM modem 11 is stored in FLASH-memory 2.

The choice of destination and setting of the route parameters in the preloaded cartographic support is carried out using the keyboard of the block 22 of the radio modules.

Data on the current congestion of roads in the FLASH-memory 2 is updated continuously, and in the absence of communication with the server 19 from the information output of the FLASH-memory 2, the last recorded data with information about the current congestion of roads comes to the information input of the main processor 6.

After applying power, successfully testing the operability of the navigation device, the device operates as usual.

Figure 2 presents graphical information displayed on the LCD-display 3 in the normal mode of operation. The display shows a fragment of an electronic map with the current location of the vehicle, an arrow at the bottom of the screen informs the user about the upcoming right turn.

The peripheral processor 7 carries out a continuous two-way exchange of technological information with the main processor 6 via a high-grade data exchange bus.

In the vehicle malfunction mode, information about the vehicle malfunction is received at the information input of the switch 4 of the LCD display 3, the switch 4 of the LCD display 3 disables the information input, which receives information from the information output of the main processor 6 and thereby provides an extraordinary output of information to LCD-display 3, namely the vehicle malfunction indicator (the belt is not fastened, the door is open, the oil level is low, etc.). If several technical parameters of a vehicle go beyond the limits of norms at the same time, several indicators appear simultaneously.

In this mode, intelligent control of the technical parameters of the vehicle is carried out. The essence of this control is as follows.

All technological information coming from the vehicle sensors and the vehicle control controller in the process of analyzing the operation of the vehicle by the peripheral processor 7 is divided into three types of information:

the first type is information from vehicle sensors that provide control of the temperature and engine speed, the voltage of the vehicle’s on-board electrical network, ABS, vehicle tire pressure, brake fluid level, pressure in the engine lubrication system;

the second type - information from vehicle sensors, providing control over the condition of the hand brake, humidity of brake pads, fastened seat belt;

the third type is information containing an engine trouble code.

The peripheral processor 7, based on the analysis of the received information from the interface module 8, changes the frequency of issuing technical information to the input of the switch 4 of the LCD display 3. On the LCD display 3 in this mode, information from the signaling device of the current malfunction and a warning about the need to stop the vehicle are displayed; At the same time, an audible warning is heard that the vehicle needs to stop.

After stopping the vehicle and turning off the ignition, the switch 4 of the LCD display 3 switches to receive information from the main processor 6, i.e. to display the current navigation information on an electronic map of the area and the car service nearest to the parking lot of the vehicle. Using the device’s control panel, the user selects the nearest car service and receives all contact information about this car service, while using the device’s service menu it is possible to send an informational SMS message (with the current vehicle coordinates) to the car service to call the technical assistance car or tow truck.

A single mode of issuing information by emergency alarms is carried out when the vehicle is parked and the ignition is switched on, it means that the radio unit 3 and the sound speaker are sent to the LCD display 3 and receive messages about the need to lower the parking brake, fasten the seat belt and dry the brake pads of the vehicle. When the vehicle starts to move, if the parking brake is not applied and the seat belt is not fastened, the indicators of the unbraked hand brake and the unfastened seat belt are continuously displayed, in the case of the handbrake being released and the seat belt being fastened, the LCD display switch (4) goes over to display the current navigation information on an electronic map of the area, with a periodic pop-up message about the need to dry the brake pads (the message appears until while the brake pad humidity sensor provides information about their malfunction).

The periodic mode of issuing information by warning lights about a vehicle engine malfunction implies the issuance of information containing an engine malfunction error code. The display of this information in the case of non-critical consequences for the engine occurs once every minute. At the request of the user, using the settings menu of the device, the specified information can be displayed once, i.e. at the time of occurrence of the engine malfunction error code 9. If there are no critical consequences for the engine, the user of the vehicle can display on the LCD display (3) the current navigation information on an electronic map and the car service centers closest to the vehicle. If desired, the user can pave the route to the nearest car service. If the engine error is critical (detonation, detonation, sensor malfunction, open circuit of the power supply to the engine nozzles, etc.), a description of the engine error is displayed on the LCD display 3. Further, the operation algorithm corresponds to the continuous mode of issuing emergency alarms.

Figure 3 presents a graphical image on the LCD display in the display mode of the vehicle malfunction signaling devices, namely:

- the seat belt is not fastened;

- low battery of the vehicle;

- low oil pressure in the engine;

- the manual brake is lifted;

- errors in the engine;

- low brake fluid level.

In the warning mode, a visual and audible indication is provided in case of exceeding the set vehicle speed. The operation of the device in this mode is similar to the operation of the device in normal mode, except that while displaying an electronic map of the area with the current location of the vehicle, a periodic pop-up message appears indicating the need to reduce speed, and an audio message is issued from the speaker of block 22 of the radio modules, which is a voice message a hint about exceeding the speed set in this section of the road.

Using the dual-processor architecture for constructing a navigation device for monitoring and controlling the technical condition of the vehicle allows independent operation of the main and peripheral processors in emergency operation mode (Fig. 4), which displays an indication of the failure of the device.

In the process of the device is a continuous monitoring of the health of the device. In the event of a failure of the main processor 6 or a malfunction of the operating system that controls the cartographic support of the device, the LCD-display 3 automatically switches to the mode of displaying information about the current speed, mileage, engine speed, side lights, low and high beam warning lights, rear heating glass and side mirrors of the vehicle, and thereby excludes the possibility of operating a faulty vehicle. This is achieved due to the fact that the lack of information from the main processor 6 at the information input of the switch 4 of the LCD display 3, provided that there is no information at the priority information input of the switch 4 of the LCD display 3, is perceived as a failure of the main processor 6 and the LCD automatically 3 information from the peripheral processor 7. However, it remains possible to monitor the vehicle.

In the event of a failure of the peripheral processor 7, the interface module 8, the switch 4, the LCD display (3), the indicator 9 of the device fails to light up, and further operation of the vehicle stops, because in this case, it becomes possible to operate a faulty vehicle, which can lead to critical consequences.

When you turn off the external power supply, the device automatically switches to work from the internal battery 13, the capacity of which is sufficient for the correct shutdown of the device and recording data in FLASH-memory 2.
