Problems solved by technology
[0003] However, when a vehicle with only a single vehicle-mounted intelligent terminal device is installed, the vehicle-mounted intelligent terminal will be intermittently disconnected from the server due to the instability of the mobile network itself when driving, resulting in a real-time connection between the vehicle-mounted intelligent terminal and the server. Poor stability, unable to achieve real-time communication

The present invention provides a vehicle-mounted communication method and system. In the method, the vehicle-mounted intelligent terminal in the power-on state receives the instruction message sent by the server; when entering the dual redundant communication mode, the main vehicle-mounted intelligent terminal and The standby vehicle-mounted intelligent terminal synchronizes the command message; the main vehicle-mounted intelligent terminal converts the command message into a CAN message and sends it to the automatic driving control unit ADU; when entering the single communication mode, the main vehicle-mounted intelligent terminal or the standby vehicle-mounted intelligent terminal The smart terminal converts the instruction message into a CAN message and sends it to the automatic driving control unit ADU. Through the vehicle-mounted communication method and system disclosed above, a dual-redundant communication mode is adopted, and when any one of the main vehicle-mounted intelligent terminal and the backup vehicle-mounted intelligent terminal is working abnormally, the other vehicle-mounted intelligent terminal communicates with the server, In this way, real-time communication between the vehicle-mounted intelligent terminal and the server is realized.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a vehicle communication method and system. Background technique [0002] With the development of society and the popularization of automobiles, in order to realize the intelligence of traditional vehicles, it is usually installed on-board intelligent terminals on traditional vehicles. The main function of the vehicle-mounted intelligent terminal is to collect information during the driving process of the vehicle through the body data bus, and then transmit the information during the driving process of the vehicle to the server through the mobile network. The server analyzes and calculates the information during the driving process of the vehicle, and then passes The mobile network sends control instructions to the vehicle-mounted intelligent terminal, and the vehicle-mounted intelligent terminal controls the vehicle to a certain extent through the vehicle body data bus, the...
