摘　　要：基于SAE的J1939协议研究开发了包括发动机ECU、牵引力控制系统ECU、自动变速器ECU和电子油门ECU在内的汽车驱动力控制系统CAN总线。使用Vector公司的CANoe研究开发了数据库文件、节点行为的CAPL文件和控制面板。进行了总线的通讯性能研究和负载率分析。完成了以电子油门ECU为真实节点的半实物仿真。结果表明:开发的CAN总线可以完成多ECU间通讯功能并满足总线实时性要求。A CAN bus integrating the engine ECU, the traction control system ECU, the automated manual transmission ECU, and the electronic accelerator ECU was developed for the automotive driving force control system based on the SAE protocol J1939. A database file, a CAPL file to describe the nodes behavior and a control panel were developed using CANoe of Vector GmbH company. The communication function of the bus was studied and the load rate of the bus was analyzed. A semi-physical simulation was performed with the electronic accelerator ECU as a real node. The results show that the developed CAN can fulfill the communication among the various ECUs and satisfy the realtimeness of the CAN.
