摘　　要：CAN总线以其传输速率高、性能好、减少车身线束使用量,广泛用于汽车电子控制系统,但随着需要传输的数据量越来越大,电子配件越来越多,使得总线负载越来越高,高负载率影响网络传输稳定性,因此,优化负载、优化网络拓扑至关重要。The CAN bus is widely used in vehicle electronic control system for its high transmission speed, good performance and less harness using amount. But with more and more data need to be transmitted and electronic control units need to be used, the busload becomes higher and higher. The high busload effects the network transmission stability, and so, optimizing the busload and the network topology is necessary.

关 键 词：总线负载率 拓扑 网络稳定性 优化
