Abstract

The message processing method, message processing device and vehicle-mounted control system provided in the present application relate to the field of vehicle-mounted control technology. In this application, firstly, a control message is generated according to the control signal to be output, and is output to the slave controller through the local Internet bus. Second, receive the response message transmitted from the controller through the local Internet bus. Wherein, the control message includes a data field, and the length of the data field is less than 2 bytes. The response message is a message obtained from processing the control message by the controller, and the length of the response message is equal to the length of the control message. Through the above method, the problem of low message processing efficiency in the prior art can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle control, and in particular, relates to a message processing method, a message processing device and a vehicle control system. Background technique [0002] Compared with the controller area network (Controller Area Network, CAN) bus, the local interconnect network (Local Interconnect Network, LIN) bus has the characteristics of low cost. Therefore, the technology based on the local Internet bus has been widely used. For example, some existing vehicle control systems are based on the local Internet bus to realize the message exchange between the master and slave controllers. [0003] The inventors found that some vehicle-mounted control systems based on the local Internet bus have low processing efficiency in the process of message interaction between the master and slave controllers, so that the vehicle-mounted control system can only be used for some real-time Control electrical equip...
