[0021] Furthermore, the Internet of Vehicles sending terminal is installed in front of the front bumper of the vehicle or in a position on the chassis close to the front bumper.
[0022] Furthermore, the Internet of Vehicles sending terminal transmits the distance L1 obtained by ranging to the Internet of Vehicles receiving terminal, and the Internet of Vehicles receiving terminal compares the obtained distance L1 with the preset value L to obtain a value Lx. When the value Lx is greater than the threshold, the Internet of Vehicles receiving terminal judges the signal as an abnormal message, and transmits the abnormal message to the Internet of Vehicles server. The Internet of Vehicles server intervenes in the vehicle braking system for braking.
[0023] Furthermore, the number of the Internet of Vehicles receiving terminals is one or more, and the Internet of Vehicles server receives one or more messages therefrom. The Internet of Vehicles server determines whether the message is an abnormal message based on the data transmitted by the Internet of Vehicles receiving terminals. Different controllable combinations can be selected for installation according to different vehicle models to adapt to different environments and improve the adaptability of the intelligent system.
[0024] Furthermore, a vehicle communication system is provided, which comprises: a vehicle network receiving terminal, a vehicle network sending terminal, and a vehicle network server, wherein the vehicle network sending terminal is used to send a first vehicle network message to the vehicle network receiving terminal; the vehicle network receiving terminal is used to execute the method described in any one of claims 1 to 5; and the vehicle network server is used to execute the method described in any one of claims 1 to 5.

[0028] Working principle: When installing the sensor, choose a suitable location for installation according to the different characteristics of the sensor to ensure that the specific beam of the vehicle-mounted sensor is used to detect the distance L. For example, when it is on a flat road, the value distance of its beam is certain. The value range of L is obtained according to the sensor angle. When there is a deep pothole on the road, set a threshold. When Lx is greater than the threshold, the vehicle will have abnormal information and face the risk of falling into the ditch. Therefore, when there is a deep ditch on the road or a deep road collapse, the distance Lx measured by the sensor will change significantly. Set a threshold P. When Lx>P, start the braking system to prevent the car from falling into the ditch.
