When moving a vehicle, the satellite navigation receiver determines the current coordinates of the vehicle, which together with its identification number via radio channel arrive at the control center, where on the monitor screen, against the background of a digital navigation map of the area, the real route of movement of the vehicle and its speed in time are revealed, its deviation from the given route and determine the compliance with the schedule of the given vehicle [2].

The method is implemented using devices that are part of a stationary control tower, and a mobile unit mounted on a mobile vehicle.

However, this method does not allow to monitor the observance of the rules of the road by vehicles, to transmit an alarm signal in case of an accident, when attacking a driver or theft, and also to act from the control point on the executive devices of the vehicle to stop it during the theft.

The known method implemented in the automotive information and communication complex [3], which allows to determine the location of the vehicle in time, its speed and the path traveled by it, accumulate navigation and telemetry information and transmit it, as well as the Alarm signal, via the communication channel to the dispatch a center for registering it on a monitor screen, diagnose vehicle components, display coordinates and speed on its digital display.

This method is implemented using technical means installed in a stationary dispatch center and including a computer with a remote communication device, equipped with a digital information input unit, a monitor with a screen, image management tools on this screen and means for generating the necessary data files, and on the transport means containing a processor, non-volatile memory, a block of sensors and actuators, and a satellite navigation receiver with a remote communication unit.

The disadvantage of this method is that it does not allow to detect violations of the rules of the road by vehicles, including the passage of intersections and crossings regulated by traffic lights, changing lanes and moving a vehicle into the oncoming lane, to identify vehicles in close proximity from the scene of the accident, identify fake government numbers mounted on the vehicle.

The task that the proposed technical solutions must solve is to eliminate the listed disadvantages of the known method of vehicle control.

The essence of the proposed method lies in the fact that in the method of monitoring vehicles, which includes placing a stationary control point equipped with a remote communication unit and a computer connected with it, equipped with an input unit for contents of a digital navigation map of the area, a monitor with a screen for visualizing digital information, means management of images on this screen and means of generating data files created in the process of vehicle control, equipment of vehicles and a navigation unit equipped with a satellite navigation receiver, a remote communication unit, a processor, non-volatile memory, an indication device, a sensor and actuator unit, determining the time parameters of a vehicle moving from a stationary control point and applying them to a digital navigation map , placement operations have been introduced in the traffic light control unit at an adjustable intersection, at a pedestrian crossing and at a fixed navigation post of the unit equipped with a satellite navigation receiver, a remote communication unit, a processor, non-volatile memory, a block of sensors and actuators and a switch connected to it, controlling the work of traffic lights, setting their operating modes, synchronizing the operating modes of traffic lights with a satellite navigation receiver, storing operating parameters traffic lights in time, changing the mode of operation of traffic lights, identifying malfunctions in their work and informing about them, equipping navigation the vehicle’s lock with a block of panic buttons for calling special services, as well as entering the vehicle’s registration data, its state number and password, which remotely connect the stationary control point to the vehicle, the border of the region in which the vehicle is currently located , the boundaries of the zones of action of road signs and their changes, transmission to a stationary control point of an alarm signal in case a vehicle violates the requirements of the road an attack on the driver, theft or unauthorized disconnection of the vehicle’s navigation unit from the on-board network, the inclusion of an audio signal in case of a malfunction, the operation of all navigation units and traffic lights in a single time, the location of the vehicle in differential mode with respect to the satellite navigation receiver, installed in the traffic light control unit and at a fixed post, identifying a fake state vehicle th number and idle navigation unit.

Implementation of the proposed method allows objectively and in a non-contact mode to detect violations of the rules of the road by vehicles, track and stop stolen vehicles, identify vehicles with a fake state number, identify the culprits of traffic accidents and find their witnesses, request and record in the navigation unit of the vehicle means necessary information about him, including the owner of the vehicle, determine the region and time finding the vehicle on its territory, as well as the path traveled with it, call, without leaving the vehicle, a special service (ambulance, fire brigade, police, technical assistance, rescue service, insurance company agent, etc.), diagnose transport means and identify a damaged or disabled navigation unit, determine the operating mode of the vehicle driver, set the operating mode of traffic lights and identify their malfunctions.

The essence of the implementation of the device for implementing the method of monitoring vehicles is that a device including a computer located at a stationary monitoring station connected to a remote communication unit and provided with an input unit for a digital navigation map of the area, a monitor with a screen for visualizing digital information and controls images on this screen, and in the vehicle itself a navigation unit equipped with a satellite navigation receiver, a distance device the communication, processor, non-volatile memory, indicating means, a block of sensors and actuators, further comprises a navigation unit with a satellite navigation receiver, a remote communication unit, a processor located in a traffic light control unit at a regulated intersection, at a pedestrian crossing and at a fixed post with known coordinates non-volatile memory, a block of sensors and actuators, the latter through a switch connected to the light devices of traffic lights and suschestvlyaet their inclusion in a predetermined order, and revealing of their faults, and vehicle navigation unit included emergency buttons unit coupled to the sensor unit and the actuator and adapted to invoke special services.

The advantage of using this device when implementing the proposed method is that it provides switching traffic lights in a single time with all navigation blocks, setting the mode of their operation in remote mode, detecting malfunctions of light devices in traffic lights and informing about these malfunctions, and the block of alarm buttons allows call various special services directly from the vehicle itself.

Figure 1 presents a diagram of the traffic situation, where 1 is a stationary control point, 2 - vehicles standing at the intersection, 3 - the vehicle that drove to the intersection, at the red (prohibitory) traffic signal, and colliding with the vehicle 4, which drove to the intersection for a permissive (green) traffic signal, 5 - a vehicle stopped in the zone of the "Stop is prohibited" sign, 6 - traffic light control unit, 7 - traffic lights themselves and 8 - stationary post.

Figure 2 presents a stationary control point with a computer 9 installed in it, to which an input unit 10, a monitor 11 with a digital navigation map 12, image management means 13 and a remote communication unit 14 are connected.

Figure 3 shows the navigation unit of the vehicle comprising a processor 15, a satellite receiver 16, a remote communication unit 14, a digital display 17, a non-volatile memory 18, a block of sensors and actuators 19 and a block of panic buttons 20. The processor 15 is based on information received from satellite receiver 16, with some discreteness in time, calculates the coordinates of the vehicle and its current speed.

Figure 4 shows the composition of the navigation unit installed in the control unit of traffic lights. It contains a processor 15 with non-volatile memory 18, a satellite receiver 16, a remote communication unit 14, a block of sensors and actuators 19, which through a switch 20 is connected to the light devices 21 of the traffic lights.

In the practical implementation of the proposed method in the memory of the computer 9 (figure 2) installed in the stationary control point 1 (figure 1), using the input unit 10 enter a digital navigation map 12 and visualize on the screen of the monitor 11 (figure 2). Using image management tools 13, which can be used as a computer mouse and keyboard, if necessary, move the digital navigation map 12 on the monitor screen and change its scale. Obtained using the remote communication unit 14, information about the traffic situation is recorded in a computer 9 as a separate layer of information, and visualized on the monitor screen 11, against the background of a digital navigation map 12.

In the non-volatile memory 18 (Fig. 3) of the vehicle’s navigation unit, upon registration (registration), the vehicle’s registration data (including the name of the owner and his home address), his state number and password are used for remote communication control point with a vehicle. In addition, the borders of the region in which the vehicle is currently located, the boundaries of the zones of action of road signs and their changes are entered into the same memory.

In the event of a traffic accident at a regulated intersection (vehicles 3 and 4) or a pedestrian crossing to a stationary control point 1, the navigation unit of these vehicles using the remote communication unit 14 (Fig. 3) transmits a message generated automatically by the processor 15 when triggered sensors located in the block of sensors and actuators 19 of the vehicle, or after pressing the corresponding panic button in block 20 (figure 3). Moreover, this information contains all the necessary data about these vehicles, including their location and time. The emergency situation is displayed on the screen of the monitor 11 (figure 2) against the background of a digital navigation map 12.

In order to identify the culprit of this traffic accident, the stationary control point 1 via remote communication channel 14 (Fig. 2) interrogates the navigation unit installed in the traffic light control unit 6 (Fig. 1) at this intersection for determining the parameters of the traffic lights at the moment occurrence of this traffic accident. To find witnesses to this traffic accident, the computer 9 (figure 2) installed in the stationary control point 1, using only the passwords known to him, interrogates the navigation blocks of all vehicles and identifies those that were in the area of the given traffic at that time transport accident. According to the coordinates, the position of these vehicles is combined with a digital navigation map on the monitor screen 11.

In case of failure of light devices at any traffic light, the navigation unit sends a message to the corresponding (repair) service via the remote communication channel.

High accuracy in determining the position of the vehicle (more precisely, the antennas of its satellite navigation receiver) is provided through the use of the differential method in which satellite navigation receivers 16, which are located in the navigation blocks installed in the control unit for traffic lights 6 (Fig. 1) and stationary post 8 (for example , traffic police post), serve as ground base stations with known coordinates [4]. Moreover, all satellite navigation receivers and the traffic light control unit operate in a single (world) time.

If the vehicle violated the requirements of the rules of the road, for example, crossed a solid line, exceeded speed, stopped in a prohibited place (vehicle 5 in figure 1), etc., then processor 15 (figure 3) first with a sound, "voice "and the text on the digital board 17 informs the driver about this violation, and after some time, if the violation continues to occur, the navigation terminal generates and via the remote communication channel 14 transmits to the stationary control point 1 (Fig. 1) an encoded message about this shenii that allows you to visualize the coordinates on the digital navigation chart 12, this vehicle.

When a vehicle crosses a region’s border in the non-volatile memory 18 (FIG. 3) of a vehicle’s navigation unit, the time and path traveled by this vehicle within it, as well as the time the driver is continuously driving, are remembered.

If a signal about theft of the vehicle was received at the stationary control point 1, then through the remote communication channels 14 (Fig. 3), which uses radio, mobile or satellite communications, a signal is transmitted via password to the block of sensors and actuators 19 (Fig. 3) the navigation unit of this vehicle to stop it (engine shutdown).

From a stationary post 8 (figure 1) remotely identify a vehicle with a disabled or faulty navigation unit. To do this, a request signal is sent in the direction of this vehicle, and if they do not receive a response signal, this indicates a malfunction or disconnection of the navigation unit in this vehicle.

To identify a vehicle with a fake state number from the fixed post 8 via remote communication, which is part of the navigation unit, the stationary number of the stopped vehicle is requested at the stationary control point 1, which remotely interrogates the navigation block of this vehicle, either by state number or by its location (coordinates). And, if these numbers do not match, then the state number attached to this vehicle does not belong to it.

Using the proposed method of monitoring vehicles and devices for its implementation allows you to remotely identify a vehicle that violated the rules of the road, who was responsible for the accident, or who was near this place at the time of the accident, who is in theft, and does not have a state number, to determine the location of the vehicle funds at a given time, the path and time of his stay in the region, as well as the time the driver was driving.
