Abstract :
With the increase of the number of electronic control units (ECUs), the integrated and smart control system in automobile is required to solve the problem of information exchange, reliability and maintenance. This paper constructed Automobile Smart and Integrated Control System (ASICS) framework with CAN bus, and designed its application layer communication protocol (XMQ J1939) refer to SAE J1939. In order to test the compliance of all ECUs, we developed Compliance Test Computer (CTC), including corresponding software and hardware. Through vehicle test, it concluded that the Automobile Smart and Integrated Control System based on XMQ J1939 work stably, with reliable data communication, favorable real time control and convenient malfunction diagnosis.
