Abstract

The invention discloses a method, a system and a storage medium for checking an automobile CAN bus error frame. The method for checking the error frame of the automobile CAN bus network includes the following steps: when obtaining an error frame in the automobile CAN bus network, identifying the network segment to be tested where the error frame is located; The electronic controller to be tested corresponding to the segment; the switch / relay preset on the electronic controller to be tested is controlled to be disconnected; when the error frame in the CAN bus network of the vehicle is detected to disappear, it is confirmed that the electronic controller to be tested is the target electronic control device. The present invention can relatively easily check and locate the controller with the error frame after the vehicle assembly is completed.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a method, system and storage medium for inspecting error frames of an automobile CAN bus. Background technique [0002] At present, the CAN (Controller Area Network, Controller Area Network) bus network is widely used in automobiles, and with the development of the automobile industry, more and more controllers equipped with the CAN bus will become available. The reliability of the CAN bus is very high, but errors still occur in some cases. CAN bus errors are divided into: CRC (Cyclic Redundancy Check, cyclic redundancy check) error, format error, response error, bit transmission error, bit filling error; when an error occurs, an error frame will be generated on the CAN bus. The error frame is also a type of CAN bus data frame, which is the frame format sent when a certain component fails or the CAN bus detects a certain node error. The generation of error frames i...
