Problems solved by technology

[0003] Since there may be multiple ECU control units in the car, in the existing detection method for multiple electronic control units in the car, it is necessary to directly add the multiple ECU control units that may exist in the car to the car list, and perform fault diagnosis one by one. More fault diagnosis time, lower efficiency

Abstract

The invention discloses a method for detecting multiple electronic control units of automobiles. The method for detecting multiple electronic control units of automobiles comprises the steps of respectively setting communication parameters of each ECU according to the type of an automobile; respectively communicating with each ECU through the communication parameters; judging whether the communication of each ECU is normal or not and adding the ECUs with normal communication to diagnosis menu list; and respectively carrying out fault diagnosis on the ECUs on the diagnosis menu list to realizethe fault analysis of the whole automobile. According to the method and device, excessive fault diagnosis time is prevented from being consumed on the ECUs which cannot work normally, and then the fault diagnosis and fault analysis efficiencies are improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method and device for detecting an automotive multi-electronic control unit. Background technique [0002] In the fault diagnosis of the car, it is necessary to communicate with the faulty ECU controller in the car through the fault diagnosis instrument, so as to obtain the fault information of the car by reading the fault code of the ECU (Electronic Control Unit) controller. [0003] Since there may be multiple ECU control units in the car, in the existing detection method for multiple electronic control units in the car, it is necessary to directly add the multiple ECU control units that may exist in the car to the car list, and perform fault diagnosis one by one. More fault diagnosis time and lower efficiency. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent....
