[0003] The disadvantage of the known device is the low functionality of the device, which consists of a small amount of information received, intended to determine the quality of driving vehicles by trainees, as well as the complexity of the design.

[0004] A device is known for measuring and recording the parameters of movement and the state of a vehicle (patent RU 2219584, 2003), as well as recording the surrounding environment, comprising a light signaling state sensor, a brake system state sensor, an analog-to-digital converter, a control unit, a timer and a memory unit. In addition, it additionally contains a speed sensor, a visual information reading unit, an acoustic information reading unit, a sensor signal pre-processing unit, an analog signal pre-processing unit and a digital information pre-processing unit.

[0005] The disadvantage of the known device is the complexity of the design and the impossibility of using it to determine the quality of driving a car.

[0006] The closest in technical essence is a device for assessing the driving quality of a combat wheeled vehicle (patent RU 2831979, 2024), containing a speedometer connected to a computing means configured to determine the acceleration of the vehicle and compare the obtained results with a range of permissible acceleration values, in which the computing means is a subscriber terminal, which additionally contains a navigation and communication means and to which a sensor for recording vibrations of the vehicle body in the vertical plane is connected, and a range of permissible values ​​of vibrations of the vehicle in the vertical plane is recorded in the memory unit of the subscriber terminal, wherein the subscriber terminal is configured to compare the determined values ​​of vibrations of the vehicle body in the vertical plane with the range of permissible values,recording the results of comparison of the acceleration of the machine and the oscillations of the machine body in the vertical plane in the memory unit and / or transmitting to the control center information about the discrepancy between certain values ​​of the acceleration of the machine in the vertical plane and the range of acceptable values, in addition, a gyroscope with a range of acceptable values ​​is additionally connected to the subscriber terminal, the device is equipped with additional subscriber terminals installed on obstacles, allowing for the detection, activation of this subscriber terminal and sensors installed on obstacles, which are sensors for detecting the approach of a vehicle to an obstacle, infrared detectors for collecting and transmitting information about entering and leaving an obstacle, or going beyond the obstacle's dimensions, two-axis sensors for collecting and transmitting information about touching limiters, falling off an obstacle, removing, processing and transmitting data about errors when overcoming them.

[0007] The disadvantages of the prototype include the complexity of the design and information processing algorithms, as well as the high inertia of the device’s operation.

[0008] The technical problem solved by implementing the proposed invention consists of eliminating the shortcomings of the analogue and prototype.

[0009] The technical result is aimed at simplifying the device while simultaneously increasing the accuracy and objectivity of assessing the quality of driving a vehicle at a driving range and a driving site in a driving school.

[0010] The technical result is achieved in that a device for assessing the quality of driving a vehicle, including a speedometer, a subscriber terminal containing a navigation and communication device, a memory unit, is additionally equipped with a controller, to which a computing module and a contactor for connecting video cameras are connected, wherein the navigation and communication device is made in the form of an OBU device with support for V2X communication technology, connected to the controller, while all elements of the device are located in a single housing.

[0011] Driving quality is determined by driving speed and the correct completion of all driving course elements with a minimum number of errors or penalty points on various obstacles. To ensure an objective assessment of the student, it is desirable that the speed data be synchronized with the exact location of the vehicle on the course, as well as the time of the speed measurement. This will allow for a more accurate assessment of the vehicle's driving quality, taking into account additional circumstances that influence driving performance.

[0012] The essence of the claimed technical solution is explained by the diagram presented in Fig. 1.

[0013] The device for assessing the driving quality of a vehicle comprises a housing 1 including a speedometer 2, a subscriber terminal 3 containing a controller 4 to which a memory unit 5, a computing module 6, OBU devices 7 with support for V2X communication technology and a contactor 8 for connecting video cameras are connected.

[0014] Vehicle-to-Everything (V2X) is a communication technology between vehicles and road infrastructure, typically the infrastructure of a racetrack or driving range. V2X utilizes two main components: the On-Board Unit (OBU) and the Roadside Unit (RSU).

[0015] OBU 7 is a device that receives data from the RSU and processes it to provide the instructor with information about the exact location of the training vehicle on the circuit, its speed, the distance and route traveled, the number of errors made by the driver, the location of their commission or traffic violations.

[0016] RSU is a device installed on the circuit's infrastructure, such as obstacle barriers, poles, road signs, and other elements, which collects data from video cameras, radars, road sign sensors, etc. The RSU then transmits the received information to OBU 7, located in the vehicle's driving performance evaluation unit, for recording in memory unit 5 and to the circuit's control unit. The RSU can also transmit information about the current state of the circuit's road infrastructure and warn the driver of potential road hazards via wireless DSRC communication, which is independent of cellular coverage and ensures near-instantaneous connection and data transmission at vehicle speeds of up to 250 km / h. The RSU acts as the "eye" of the circuit's infrastructure, collecting and transmitting important vehicle movement data to improve the quality and objectivity of driving assessment within the V2X system.

[0017] Using V2X allows for objective assessment of vehicle driving performance on the track and increases the efficiency of the track's infrastructure by increasing the number of trainees simultaneously performing practical driving exercises. The RSU and OBU 7 are key V2X components that provide communication between vehicles and the track's infrastructure.

[0018] The claimed technical solution works as follows.

[0019] The vehicle driving quality assessment device is used during practical driving exercises on a driving range. While the vehicle is moving, the device measures its speed using speedometer 2, sending the data to computing module 6, which is part of user terminal 3. Computing module 6 also receives information from OBU 7 via controller 4 regarding the training vehicle's exact location on the driving range, its speed, the distance traveled, the route, the number of errors committed by the driver, the location of these errors, and any traffic violations. Additionally, it is possible to connect video cameras to the device via contactor 8 to visualize the driver's actions and the traffic situation. Final processing of the information before sending it to the driving range control center occurs in computing module 6.The OBU 7 device receives the above information from the RSUs installed on the circuit infrastructure using V2X communication technology. This technology also enables the transmission of information from the computing module 6 via the RSUs and OBU 7 to the circuit control center, where the instructor uses it to evaluate the vehicle's performance.

[0020] When implementing the device in relation to vehicle driving quality control, the V2X communication technology records:

[0021] 1. Obstacle avoidance.

[0022] 2. Obstacle overcoming speed.

[0023] 3. Touching the limiters.

[0024] 4. Falling off an obstacle.

[0025] 5. Exceeding the obstacle clearance.

[0026] All information processing and exchange between the vehicle and the track control center occurs in real time at high speeds via DSRC wireless communication.

[0027] Thus, the proposed technical solution allows for the simplification of the device by eliminating the radio navigation module and communication module, the body vibration sensor and the gyroscope, and also for increasing the accuracy and objectivity of assessing the driving quality of a vehicle on a driving range or a driving site by using V2X communication technology.
