Description

Useful refers to radio engineering and can be used for diagnostics, control of car units, as well as for vehicle protection and acceleration of operational-search measures when searching for vehicles. It is possible to use such a system for wireless control of remote stationary objects.

The prior art method for remote control of the vehicle (A) (patent RU 2163871, B60R 25/00, G08C 17/02), comprising a radio communication device, security and anti-theft blocks, a switch, a logical node, which improves the efficiency and reliability of vehicle protection .

The essence of this method is the transmission of commands encoded additionally by logical signals and the installation of an additional key on a logical device in the TS, however, scanning by the receiver of such commands and writing them to memory can allow attackers to take possession of the TS.

Also known is a telematic security and anti-theft system (RU 2195406, B60R 25/00, G08B 25/08) containing a local area network controller TC connected to a common vehicle multiplexer bus and to a controller-converter of a data exchange protocol associated with a transmission and reception unit data and a unit for remote identification of the user of the vehicle, consisting of contactlessly connected wearable part and a transportable part connected to the controller of the subsystem. Nevertheless, the connection of additional electronic equipment to the standard electronic system of the vehicle, the user identification unit containing the WEB server, and the local connection modem in the Bluetooth protocol will not significantly reduce the likelihood of unauthorized use of the vehicle, because it can be scanned by Bluetooth or Wi-Fi devices and analyze the controller protocols of the proposed security and anti-theft subsystem.

The WAY OF WORKING THE ON-BOARD SYSTEM OF CONTROL OF UNITS OF THE CAR (RU 2126960, G01M 17/00, B60Q 9/00, B60R 16/02). The proposed method extends the functionality of the on-board system. The specified method of operation provides for pre-exit verification, as well as subsequent monitoring of vehicle parameters. The disadvantage of this system is the inability to protect the vehicle. The closest solution is the ANTI-THEFT SYSTEM FOR VEHICLES (RU 2198801, B60R 25/00). This system is characterized by increased reliability against vehicle theft and provides the user with the ability to safely communicate with the outside world on a cell phone while the vehicle is moving. The disadvantage of this system is the lack of functions for checking vehicle parameters.

The technical result of the claimed utility model is to provide the vehicle owner with the possibility of automatic control of the vehicle’s units, automatic diagnostics, including pre-exit checks, vehicle security functions, as well as information reporting options when the vehicle is stolen to speed up and facilitate search operations. It also implements modular design and the ability to change the configuration of system nodes.

The specified technical result is achieved due to the fact that the automatic control system for vehicle aggregates and vehicle security containing an electronic node consisting of a car alarm unit, which includes a radio frequency signaling unit, a navigation and satellite communication unit, a tachograph unit with input signal and output signal modules and controller; control unit, characterized in that the car alarm unit additionally includes an identification tag reader, and the control unit is made on the basis of a reprogrammable controller implemented on the principle of a system bus with the ability to expand or change blocks and modules with the option of reprogramming the system operation algorithm.

The system (see Fig.) Uses an electronic unit consisting of a car alarm unit 1, which contains two parts - a radio frequency signaling unit and an identification tag reader, navigation and communication unit 2, which includes GSM and GLONASS \ GPS modules and / or a radio transceiver \ infrared optotransiver backup communication channel; tachograph unit 3 and control unit 4.

The control unit processes data from the car alarm unit, the navigation and communication unit, and the tachograph unit. The issuance of commands, processing and transmission of data is carried out by the control unit according to an internal algorithm. This algorithm contains options for checking and diagnosing vehicle parameters and the system’s actions corresponding to the measured data, options for protecting the vehicle from theft, and also options for responding to possible theft.

Structurally, the system consists of a motherboard cross-board and blocks and modules installed in it.

The advantages of this PM include the modular design and the ability to change configurations, as well as reprogramming the algorithm. For example, the navigation and communication unit together with the control unit can work as an independent device and can be installed together with any alarm system; special external input and output can be used to connect as an external sensor and actuator to any alarm. The control unit together with the GSM module of the communication navigation unit (without the GLONASS \ GPS module and without the backup channel module) is a wireless security system with cell phone options and can be used to protect fixed objects (buildings), such as apartments, houses, cottages, warehouses , offices, etc.

Another advantage is that the use of a control unit together with an alarm unit provides a system for restricting access to an object through the use of two elements of a user identification system: a tag and a key fob.

In addition, a system comprising a navigation and communication unit (GSM module), a control unit, and a tachograph unit with an input-output interface module can perform functions of wireless control of remote objects (Smart Home system). The proposed system allows you to identify the user of the vehicle using the RFID tag without an autonomous power source, using two-way data exchange with the identification unit and working at a small (10-50 cm) distance, which can significantly reduce the likelihood of interception of data exchange by an attacker and falsification of an identification key, and as a result unauthorized use of the vehicle. The effectiveness of protecting the exchange of RFID tag data with the identification unit is achieved using an encryption algorithm, which makes it difficult to select or simply copy the transmitted information. Radio interception is practically impossible due to the small distance between the tag reader and the access key. The system operation algorithm is designed so that access to the vehicle is carried out only by means of a radio tag (access key), i.e. implies the physical presence of the owner, driver or agent. The movement of the vehicle without a RFID tag is impossible, and thus, in case of capture of the vehicle while driving, or in the autostart mode or remote start of the engine, the engine will be shut off, simulating a malfunction. The remote control is used to issue commands, for example, remote start the engine or open doors, configure the autostart system, and receive information from the system, for example, indicating the current state of the security system and displaying parameters: engine temperature, air inside the vehicle and outside, battery voltage, Indications of engine operation, status of protection zones, settings of the autostart system (temperature, time, period). The keychain is equipped with a feedback system. Radio communication is carried out using an encryption system, which improves the security of the radio channel from unauthorized interception of data. The key fob uses battery power; in stationary conditions, it is possible to use a network power source - in this case, the security system operates in the radio anchor mode: there is a continuous radio exchange of the key fob with the vehicle alarm system.

The input and output modules of the tachograph unit are used to receive signals from transmitters and send commands to actuators to control security zones, remotely start the engine, control the starter, gas pump, headlights, and ignition.

Identification and RFID reader modules determine system parameters for user access using a RFID tag, exchanging data with a key fob, configuring auto-start parameters of an engine, controlling an alarm, controlling a GLONASS / GPS + GPRS navigation and communication unit. Security zones include:

- Driver door limit switch

- fuel pump power control output

- GLONASS / GPS + GPRS navigation and communication control unit

- ignition control output

- starter control output

- headlight control output

- siren control output

- central locking control output

- tailgate lock control output

The navigation and communication unit contains the GLONASS / GPS module and the GSM \ GPRS module, which are used to determine the location of the vehicle using the GLONASS / GPS satellite navigation system, transmit information to the user via the Internet using the GPRS modem and / or CMC messages, configure the GPRS modem, for control the alarm system in case it is not possible to use the key fob, as well as for processing and exchanging data with the tachograph unit, and transmitting this data to the user via the Internet or SMS / MMS message.

The navigation and communication unit has an autonomous power source (battery), which is activated in the absence of on-board voltage.

The tachograph unit is used to read information from the input signal module, to send commands to the output signal module, to record and store data of the navigation system, data on engine operating time, idle time, average and maximum speed, mileage, alarm system status, and identification data recording TS user.

The unit has a flash drive slot for storing tachograph data. The car alarm unit comprises an identification reader module and a radio frequency signaling module. If necessary, the unit can be supplemented with a backup radio channel or optical infrared communication channel. The control unit is made according to the principle of a system bus with the ability to increase or change blocks and modules and contains a controller with the algorithm of the system operation recorded in it. The presence of the controller reprogramming connector allows you to change the algorithm of the system to any other, thus, the system as a whole is a reprogrammable highly intelligent machine.

The operation of the device is as follows.

To remove the system from the armed mode, press the corresponding button on the key fob. The alarm unit, having received a command from the key fob, generates a data request for the RFID tag, which processes the received information and sends it to the alarm unit. Improving the cryptographic stability of the data exchange between the key fob and the alarm unit, and the alarm unit and the RFID tag is achieved using a dynamically changing sequence, which complicates unauthorized access to the vehicle by intercepting radio communication between the key fob and the alarm unit. Thus, disarming the system is impossible without interaction with the RFID tag, which implies the physical presence of the owner near the vehicle. The system will notify the user of the vehicle about disarming with the help of sound and light alarms and on the key fob display.

To place the system in arming mode, you must press the corresponding key fob button. In this case, two-way radio data exchange occurs between the key fob and the alarm unit using a dynamically changing sequence.

After receiving a command to put the system in security mode, the system closes the central lock and checks all security zones. If an error is detected (any of the sensors is faulty), the system will notify the user of the vehicle of the malfunction with the help of sound and light alarms and on the key fob display. The status of the security system is displayed by the corresponding icon on the key fob display and light indication in the vehicle interior.

In security mode, the system monitors the status of security zones, the presence and voltage level of the on-board network, temperature sensor readings and controls the location of the vehicle, receiving data from the navigation and communication unit, and periodically exchanges data with the key fob.

If autostart / remote start of the engine is enabled by the system settings, then upon receipt of a command to remotely start the engine from a key fob or SMS message of the appropriate format from the navigation and communication unit or the autorun command for temperature and / or timer settings, the security system starts the engine when certain conditions: the parking brake lever is raised, the voltage of the on-board network is not lower than the permissible level, the engine is not started. In the autostart / remote start mode in case of vehicle location change according to the navigation block system data, or the limit switches of all doors, trunk lid and hood, motion sensor, GLONASS / GPS signal disappear (if this option is enabled), GSM (if this option is enabled ) or a key fob when operating in the beacon mode (if this option is enabled), an anti-theft system is activated, which shuts off the engine, blocks the ignition, the fuel pump and starter power circuits, and turns on the sound and light alarm system It sends a corresponding command to the key fob, and also sends a CMC message to the vehicle owner (if this option is enabled) and sends the vehicle coordinates to the Internet via GPRS (if this option is enabled).

The engine status is indicated by the corresponding icon on the key fob display. Also, the display shows in the form of a symbol whether autostart / remote start of the engine is enabled or disabled. Thus, the system notifies the user about the possibility of autostart / remote start. The likelihood of starting the engine with the gear engaged is excluded by checking the “logical neutral” signal. The range of this function is as follows: at the end of the trip, the driver puts the car on the parking brake, turns off the transmission, i.e. puts the gearshift lever in the neutral position, pulls out the key from the ignition switch and exits the vehicle. The engine is running at this time. Then it puts the system into guard mode, and the engine turns off after a few seconds.

The navigation and communication unit incorporates a GLONASS / GPS module, GSM \ GPRS module and works as follows. GLONASS / GPS module receives a signal from navigation satellites and transmits data to the control unit. The module always works after the engine starts, and in the armed mode it either switches to low power mode or is always on (depending on the user's settings). The control unit receives data from the GLONASS / GPS module and the GSM module and controls their operation. In the security mode, in the event that the sensors of the security zones are triggered or the coordinates of the vehicle are changed, the control unit transmits data to the user via GPRS and / or CMC messages and through the alarm unit to the keyfob. If the navigation satellite signal disappears, the control unit sends the last received coordinates via the GSM cellular communication channel, which narrows the vehicle search circle in the event of theft and hiding in the garage box, which facilitates the vehicle detection task. The tachograph writes the following data to the flash drive: time, engine temperature, air, engine operating time, speed, coordinates, fuel level, on-board network voltage, as well as information from the alarm unit. Structurally, it can be performed both jointly and separately from the communication and navigation unit.

As a device that sets the operating modes, use mainly reprogrammable microprocessor.

Such a system allows you to switch to an even higher level of vehicle safety and service capabilities.

Thus, the combination of the essential features of the prototype device and the features newly introduced by the applicant allows us to solve the above problem - to increase the flexibility of controlling the units of the vehicle and increase the reliability of protection and facilitate the search for vehicles in the event of theft.

The advantages of this solution include modular design and the ability to change the configuration of nodes, as well as reprogramming the algorithm. For example, the navigation and communication unit together with the control unit can work as an independent device and can be installed together with any alarm system; special external input and output can be used to connect as an external sensor and actuator to any alarm.
