Technical field

The invention relates to transport telematics, in particular, to an automotive telematics device for remote diagnostics, navigation and remote control of vehicle functions.

State of the art

Automotive telematics consists in the use of computer, sensor and telecommunication technologies for the remote provision of services. The main categories of telematic services are navigation, remote diagnostics, fleet management, security, multimedia functions, communication and access to information. In addition, when creating telematics devices, confidentiality and data security must be ensured.

From the current level of technology, the 3S-Telematica service security system is known. The system includes a GLONASS / GPS / GSM multisystem unit, a service button for communication with a dispatch center, an EDR accelerometer, which is an accident sensor, an immobilizer that provides protection against vehicle capture and wireless engine blocking, a roll / displacement sensor, a volume sensor for detecting entry into the car , an application server and a mobile application for a smartphone that allows the owner to remotely control and manage system functions (see information on the Internet: http://3s-t.ru/uslugi/ohranno-poiskovye- sistemy-bezopasnosti / r-2.htmn .

The system provides vehicle condition monitoring through the dispatch center determines its location and analyzes the driving style, which allows the car owner to use the technology of "smart" insurance (when calculating individual auto insurance rates, information about mileage and other vehicle motion parameters obtained using telematics systems). Using a mobile application, the system user can determine the location of the car, remotely control the functions of the car (when installing additional equipment) and call the operator of the dispatch center.

The disadvantages of this system is the need to install additional equipment for the ability to control the functions of the car, for example, remote start / stop the engine, open / close doors, control dimensions, open the trunk, control horn. In addition, there is no function to notify the car owner or interested parties directly in the event of an accident, hacking or other emergency situations.

Security systems are known that have a set of security, anti-theft and service functions, such as opening / closing doors and windows, remote engine start / shutdown, control of the horn, side lights, etc. Such systems have a modular architecture and can be equipped with GSM / GPS security and search. module, as well as a CAN module when installed on a vehicle with a CAN bus. (see information on the Internet: http: // www. u ltrastar.ru. Alarms with a GSM / GPS module in addition to standard functions provide positioning, notification of the state of the car (hacking, theft) and remote control of security complexes and additional equipment, for example, a pre-heater. Management of the complex and its partial configuration can be carried out by the car owner through a mobile application for devices on the iOS and Android platforms or through an Internet service.

Such complexes represent a convenient and reliable car security system, but are not aimed at providing the car owner or interested parties with additional service capabilities, for example, providing information on the technical condition of the car or on the driving style of the car, which may be necessary for car insurance.

The signaling system for guarding and monitoring a vehicle is known, which consists of a GPS / GPRS DiZicBee head control unit with a GSM signal and transmitter module and a GPS beacon connected to a remote control and a remote control server, from mechanisms and light control modules, from blocking relay module, from the shock detector module and the volume sensor module, from the glass breaking sensor module and the remote module for gate control. The head control unit is connected wirelessly with a remote control, a remote control server and with all modules, and is equipped with computer software to provide the client with control of the driving route and alarm status, and software for the smartphone to provide the client with control of the driving route, alarm status, settings her, remote locking of the engine or its start-up, tracking on-line, monitoring the dates of movement of the car with reference to the time zone s (RF Patent Ns 106194, B60R25 / 00, G07C5 / 00 publ. 07/10/2011). The system allows the owner of 85 using a mobile application to remotely monitor the condition of the car, control functions, determine its location.

This system provides the owner with a full range of security and anti-theft functions, but does not provide for the transfer of 90 information about the technical condition of the car.

The implementation of the invention

The telematics device for car 1 includes a GPS module 2; GSM module 3, which transfers data between equipment 1 and the remote server 10, to which end users connect via software 11 on their smartphone (on the iOS, Android, Windows Phone platform) or via the website 12; module for detecting shock and movement of the vehicle 4; built-in temperature sensor 9, power relay module 5, which controls the start / stop of the engine, analog relay module 6, which controls the low-current circuits of the vehicle (opening / closing doors, opening the boot, giving an audible signal, turning on / off the side lights); CAN module 7, implemented as two independent CAN (Controller Area Network) interfaces; LIN (Local Interconnect Network) module 8 for interfacing with a protection device unauthorized engine start (immobilizer).

The telematics device for vehicle 1 operates 140 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 of car accessories, protection device against 145 unauthorized engine starts (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. To the server 10 as well 150 connect end users 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.

155 Industrial Applicability

First, the device 1 is configured, i.e., the software sets up the operation modes of various nodes and sets up the functions performed. The configuration of the device 1 or the software update of the device 1 is carried out using 160 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 device 1 and determines based on the criteria (hardware version 165 devices, 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

170 is loaded into the temporary memory of the device. Updating is carried out only if the car does not move and the engine has not been started. In the event of a successful software update, device 1 reports this to server 10. In the event of a failed update, device 1 reports this

175 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. Device setup

180 is carried out by sending commands from the site 12 through the server 10 to the device 1. The operation of the LIN module 8 with the engine protection device from unauthorized start (immobilizer) is configured by recognizing the immobilizer key code during engine start-up. Startup must be done 3 times, key

185 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. Setting the operation of the power relay module 5, analog relay module 6,

1 90 CAN module 7 is carried out in accordance with the make and model of the car, and these settings are transmitted to device 1 in the form of a configuration file. The device 1 using the GPS module 2 can determine the current location of the car and record the movement of 195 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 200 direction of movement of the car to server 10.

Server 10 sends the vehicle location information to the owner’s smartphone with software 11.

Device 1 is a permanent recording of the movement of the car. When connecting device 1 to server 10, information about

205 movements are transferred to the 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. In case of achievement

210 limits, the device begins to delete 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 the 215 lc GPS module 2 is transmitted to the server 10. At the time of receiving data on the vehicle’s location outside the specified radius / perimeter, the server 10 sends a notification about the vehicle’s location to the PUSH’s smartphone. 220 Device 1 starts the car engine through the power relay module 5. 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 recognized

225 key code device setup, 2 second delay, ignition feed. The device can start the engine when using the software 11 for a smartphone by selecting the appropriate functionality, when a specific event occurs: device temperature, temperature

230 environment has become lower or higher than the threshold indicated in the software 11 on the smartphone of the car owner. The device temperature is determined using the built-in temperature sensor 9, the ambient temperature from an external Internet resource: server 10 receives GPS coordinates from the device, does on

235 an external Internet resource request 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. Device 1 transmits

240 information about successful / unsuccessful launch on a smartphone with software 11 through server 10.

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 245 via the CAN module 7, or through the analog circuit through the analog relay module 6 after receiving the corresponding command from the owner’s smartphone through the server 10. Specific control mode depends on the configuration file that was transferred to device 1 at the time of its configuration through server 10.

250 Device 1 contains a module for detecting shock and movement of vehicle 4, which is an integrated accelerometer that analyzes the current position of the vehicle relative to three coordinates. If the car has sharply moved, was substantially tilted relative to the horizon, moved vertically,

255 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

260 provides the necessary information for service centers, insurance companies, etc. Service centers receive information on the technical condition of the car, which allows them to promptly invite the car owner for maintenance. A specialized site receives data on the current mileage, about

265 errors in the vehicle’s system, which are diagnosed electronically, speed data based on GPS data, door / trunk opening / closing status, engine speed data. Using a specialized website, insurance companies receive reports with the results of an analysis of their driving style, which allows

270 use in calculating individual rates for auto insurance.

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 generated based on device 1 reading the sensor signals and indicators

275 shock and movement of the car 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.

Despite the complexity and versatility of the device, 280 it has small dimensions, which makes it possible to install it in any inconspicuous place in the car. In addition, due to its multifunctionality integrated in one device, the claimed invention simplifies and speeds up the installation process of equipment, due to the lack of a large number of blocks, modules, etc.

285 The claimed invention allows the car owner to get the maximum number of functions using a smartphone through one telematics device, which makes the process of monitoring and controlling his car the most convenient and economical.
