结合汽车道路性能测试特点,给出制定CAN总线通信协议应遵循的基本原则,设计了网络拓扑结构,在借鉴J1939等CAN总线应用层协议的基础上设计出了适合于汽车道路性能测试的CAN总线通信协议,协议有效性在GCM06型机动车道路性能综合测试仪中得到验证。
Considering the characteristics of vehicle road testing, this paper proposed the basic principles of making the CAN bus protocol and constructed the network topology. Then, the CAN bus protocol adapting to the characteristics of vehicle road testing was designed on the basis of CAN bus application layer protocol such as J1939. And the effectiveness of the protocol has been verified by the GCM06 (the vehicle road testing system) developed independently.
