CAN protocol generation method and device, and vehicle with CAN protocol generation device

Abstract

The invention discloses a CAN protocol generation method and device. The CAN protocol generation method comprises the following steps: reading a target requirement file; generating a signal requirement list file according to the target requirement file; performing comparison and analysis on the signal requirement list files according to a preset model to obtain the allocation strategy for multiple controller signals; and generating the CAN protocol according to the allocation strategy. The CAN protocol generation method can shorten the time of the protocol generation, therefore, the errors caused by multiple modifications are avoided, and the safety of the vehicle is improved. The invention also discloses a vehicle with the CAN protocol generation device.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a CAN (Controller Area Network, Controller Area Network) protocol generation method and device and a vehicle having the same. Background technique [0002] With the development of automobile technology and the application of bus technology, more and more nodes follow the CAN protocol on the automobile. At the same time, with the gradual access to the Internet, vehicles have various functional requirements, resulting in more and more requirements for the development cycle, which in turn leads to the need for continuous modification and verification of the vehicle protocol, and the shortening of the development cycle will lead to Some errors are inevitable, especially the CAN bus signal list of electric vehicles is mainly modified and written manually, which may easily lead to unnecessary errors in the reliability and consistency of the protocol due to some unnecessary mis...
