Telematics device for car 1 operates as follows. Device 1 is installed in the car and connected, depending on the make and model of the car, to the following digital and analog lines: internal CAN bus, external CAN bus, ignition, starter, brake pedal sensor, power supply for car accessories, protection against unauthorized engine starting ( immobilizer), horn, parking lights, central locking, door limit switch, trunk limit switch, tachometer signal input, car interior temperature sensor. Device 1 through the built-in GSM module 3 is connected to a remote server 10. End users also connect to server 10 using software 11 on their smartphone. Data is transferred between device 1 and server 10 via a VPN (Virtual Private Network) channel without access to the public Internet, which provides a high degree of protection.

First, device 1 is configured, i.e. software configuration of the operating modes of various nodes and tuning of the functions performed. The configuration of the device 1 or the software update of the device 1 is carried out using the website 12.

The update is carried out as part of the following algorithm. The server administrator through the website 12 adds to the server 10 a new version of the software for the device 1 and determines on the basis of the criteria (hardware version of the device, release date) which hardware parts of the device should be updated. The server 10 during the next communication session with the device 1 informs him that it is necessary to update the software of the device 1 and transfers the data updates. Updated software is downloaded to the device’s temporary memory. Updating is carried out only if the car does not move and the engine has not been started. In the case of a successful software update, device 1 reports this to the server 10. In the case of a failed update, device 1 reports this to the server and restores the original software.

The configuration of the device 1 is carried out during the initial installation. The installer gains access to a specialized web site 12, through which performs the initial configuration. The device is configured by sending commands from the site 12 through the server 10 to the device 1. The LIN module 8 is configured to work with the engine protection device against unauthorized starting (immobilizer) by recognizing the immobilizer key code during engine start-up. Start-up must be carried out 3 times, the key of the immobilizer at the time of recognition should be in the coverage area of the immobilizer. This code will be used every time device 1 starts the car engine, without using the traditional immobilizer walker with a key. The operation of the power relay module 5, analog relay module 6, CAN module 7 is configured in accordance with the make and model of the car, and these settings are transmitted to device 1 as a configuration file.

Device 1 using GPS module 2 can determine the current location of the car and record the movement of the car.

The car owner using software 11 on his smartphone sends a request to determine the current location of the car to server 10, the server sends a request to device 1 via the VPN channel, and the device transmits the received coordinates, speed and direction of movement of the car to server 10. Server 10 sends the location information car to the owner’s smartphone with software 11.

Device 1 is a permanent recording of the movement of the car. When device 1 is connected to server 10, movement data is transmitted to server 10 and stored on it in the DBMS. The owner of the car can access the data through the software 11 on the smartphone. If there is no connection to the server 10, device 1 accumulates the values in the permanent memory until its limit is reached. If the limit is reached, the device begins to delete the old values and write new ones in their place.

Using software 11 on a smartphone, the car owner can set the radius or perimeter within which the car is considered to be correct. Data from device 1 with GPS module 2 is transmitted to server 10. At the time of receiving data on the vehicle’s location outside the specified radius / perimeter, server 10 sends a notification with information about the vehicle’s location to the smartphone of the vehicle owner PUSH.

The start is carried out in the following sequence: ignition, 2-second delay, brake pedal signal, 2-second delay, signal to the immobilizer module key using the key code recognized when setting up the device, 2 second delay, ignition feed. The device can start the engine when using the smartphone software 11 by selecting the appropriate functionality, when a certain event occurs: the device temperature, the ambient temperature has become lower or higher than the threshold indicated in the software 11 on the smartphone of the car owner. The temperature of the device is determined using the built-in temperature sensor 9, the ambient temperature from an external Internet resource: the server 10 receives GPS coordinates from the device, makes a request to the external Internet resource with the transfer of coordinates, and receives the temperature value for the specified coordinates. After starting the engine, device 1 will check whether the engine is actually running through the CAN module 7, which interacts with the vehicle’s CAN bus, or through the analog input of the tachometer signal. The device 1 transmits information about the successful / unsuccessful launch to the smartphone with software 11 through the server 10.

The device 1 controls the opening / closing of the central lock, doors, car trunk, the sound signal through the horn, the side lights via the CAN bus of the car via the CAN module 7, or through the analog circuit via the analog relay module 6 after receiving the corresponding command from the owner’s smartphone through the server 10 The specific control mode depends on the configuration file that was transferred to the device 1 at the time of its configuration through the server 10.

The device 1 contains a module for detecting shock and movement of the car 4, which is a built-in accelerometer that analyzes the current position of the car relative to three coordinates. If the car has moved sharply, has been substantially tilted relative to the horizon, moved vertically, this event is transmitted to the application server 10, the server sends a PUSH notification to the smartphone of the car owner.

The device 1 through the server 10 is able to transmit information about the technical condition of the car to users on a specialized web site that generates reports and provides the necessary information for service centers, insurance companies, etc. Service centers receive information about the technical condition of the car, which allows them to promptly invite the car owner for maintenance. The specialized site receives data on the current mileage, on errors in the car’s system, which are diagnosed electronically, data on speed based on GPS data, on the status of opening / closing doors and trunk, data on engine speed. Using a specialized website, insurance companies receive reports with the results of an analysis of their driving style, which makes it possible to use individual rates for car insurance in the calculation. Information about the mileage and other parameters of the car’s movement obtained using the telematics device is taken into account. Reports for service centers and insurance companies are formed on the basis of the reading by the device 1 of the signals and indicators of the shock sensor and the vehicle 4, temperature sensor 9, GPS module 2 and CAN module 7.

The use of all functions of the device is possible in the territory where a GSM signal is present.
