The vehicle detection method provided by the embodiment of the application can be applied to terminal devices such as RSU (road Side Unit), and the like, and the embodiment of the application does not limit the specific types of the terminal devices.

In recent years, although vehicle detection technologies are widely popularized and developed to a certain extent, the existing vehicle detection technologies still mainly detect various running states of vehicles by holding vehicle detection equipment by workers, so that a large amount of manpower and material resources are consumed, and the problems of high detection cost and low efficiency are caused to a certain extent. In order to solve the problem, the application provides a vehicle detection method, a vehicle detection device, a terminal device and a computer readable storage medium, when a vehicle is detected to reach a preset detection area, the OBU is subjected to function self-detection and performance detection based on communication between the RSU and the OBU, the vehicle detection efficiency and precision are improved, and normal operation of the vehicle is guaranteed.

To implement the technical solution proposed in the present application, a vehicle detection system 100 may be constructed first. Referring to fig. 1, the vehicle detection system is composed of more than one RSU101 (only 1 is shown in fig. 1), a position detection device 102, a vehicle (the vehicle is equipped with an OBU), a display device 103 and a detection device 104, and the RSUs are respectively connected with the position detection device 102, the OBU, the display device 103 and the detection device 104 in a communication manner.

The position detecting device 102 is a sensing device for detecting a position of the vehicle and determining whether the vehicle reaches a predetermined detection area, and is generally set in front of the predetermined detection area. The RSU is a terminal device for transmitting a detection command to the OBU and receiving detection data and a detection result returned from the OBU, and is generally set in a preset detection area. An OBU (On board Unit) is a microwave device that communicates with an RSU using dsrc (dedicated Short Range communication) technology. The display device 103 is used for displaying the detection result and/or prompt information. The detection device 104 is configured to store the detection data and the detection result, and generate corresponding prompt information when the detection result does not meet a preset requirement.

During the driving of the vehicle, when detecting that the vehicle reaches the preset detection area, the position detection device 102 sends notification information that the vehicle reaches the preset detection area to the RSU 101; when determining that the vehicle reaches a preset detection area, the RSU101 sends a detection instruction to the OBU and receives corresponding detection data and a detection result; when the OBU receives the detection instruction, the OBU executes a corresponding detection program based on the detection instruction, and sends corresponding detection data to the RSU101, and the RSU101 sends the detection data and the detection result to the detection device 104, and sends the detection result to the display device 103 for display.

In order to explain the technical solution proposed in the present application, the following description will be given by way of specific examples.

Example one

Fig. 2 shows a schematic flow chart of a vehicle detection method provided by the present application, which may be applied to the RSU described above by way of example and not limitation, the RSU being in communication with the OBU.

Specifically, when the vehicle sent by the position detection device (the position detection device 102 is installed in front of the preset detection area and can be set as side-mounted or top-mounted) in communication connection with the RSU reaches the prompt message of the preset detection area, a function self-check instruction is generated and sent to the OBU, so that the OBU performs function detection according to the function self-check instruction, and receives a function self-check result returned by the OBU. The function self-checking instruction is a control instruction for controlling the OBU to execute a corresponding function detection program. The position detection device includes, but is not limited to, a positioning radar, a camera, a magnetic induction coil detection device or an infrared detection device, and can acquire position information of a vehicle near a preset detection area in real time and trigger communication between the RSU and an OBU in the vehicle when the vehicle is detected to reach the preset detection area.

Otherwise, when the function self-checking result is detected to be a detection failure, the detection program of the OBU is terminated, prompt information of the function failure of the OBU is generated and displayed through the display device, and therefore a user is prompted to carry out detection and maintenance on the OBU. Or when the performance detection result is detected to be detection failure, the performance fault of the OBU is judged, the detection result is sent to the detection equipment, and the detection equipment generates performance fault prompt information and displays the performance fault prompt information through the display device so as to prompt a user to further detect and calibrate the performance parameters of the OBU.
