Abstract: With the development of automotive electronic technology and the improvement of vehicle performance requirements, the number of vehicle electronic control units is increasing, and the interactive information between each electronic control unit, intelligent sensor and intelligent actuator is becoming more and more complex. Network communication has become the basic technology to ensure the normal operation of each node. Based on the development and verification of commercial vehicle controller area network, this paper introduces the test process and test method of commercial vehicle controller area network automatic test. Based on this process and method, by analyzing its test requirements, the test cases are compiled, and the automatic test process is formed. The controller area bus network automatic test of each electronic control unit node of a commercial vehicle is realized. The automatic test system ensures the efficiency and accuracy of the test, and improves the efficiency and reliability of the whole model project.
