基于CAN总线的车门控制系统的设计与实现

Design and Implementation of Door Control System Based on CAN Bus

为减少车身内不断增加的线束,提出了一种基于CAN(Controller Area Network)总线的车门控制系统的实现方案,参考SAEJ1939协议对CAN总线应用层协议进行了定义,最终实现了一套由四个车门组成的CAN总线控制系统,是整个车身控制系统(BCM,Body Control Module)的核心组成部分,为构建包含车灯在内的整个车身电子电器的网络化控制系统奠定了技术基础。

To reduce the growing wire harness in the vehicle, presented a realization of Door Control System based on CAN （ Controller Area Network） bus, defined the application-layer protocol of CAN bus referring the SAE J1939, finally achieved a complete network communication system. The door control system is composed of four door control modules, all modules connected by CAN bus. Itg the core part of the whole body control system.
