Abstract

The embodiment of the invention discloses a CAN (Controller Area Network) channel adaptation method, device and system and an automobile. The method comprises the following steps: receiving messages which conform to the same communication protocol from N CAN channels, wherein N is a natural number being greater than or equal to 2; judging information corresponding to the CAN channels satisfies a preset condition or not respectively; setting corresponding identifiers for the CAN channels in response to the fact that the information corresponding to the CAN channels satisfies the preset condition; and sending response messages to the CAN channels according to the corresponding identifiers set for the CAN channels. Through adoption of the CAN channel adaptation method, device and system and the automobile, the problem of over-high communication load rate of a CAN bus can be solved.

Description

technical field [0001] The invention belongs to the field of CAN bus, in particular to a CAN channel adaptive method, device, system and automobile. Background technique [0002] With the increasing number of Electronic Control Units (ECUs) in automobiles, the CAN bus network topology used for communication between ECUs is becoming increasingly complex, and the communication load rate is also increasing. [0003] In electric vehicles, the battery management system (BATTERY MANAGEMENT SYSTEM, referred to as BMS) is responsible for the charge and discharge management of the high-voltage power battery. It has at least three CAN channels, one for vehicle CAN bus communication, and one for real-time internal data of the BMS. Acquisition, all the way for charging. If no separate calibration channel is designed, we usually need to add the calibration function of the BMS to the channel used by the BMS for the CAN bus communication of the vehicle, so that the online calibration of t...
