基于CAN总线的车辆电子驻车制动系统的设计

摘要

CAN bus-based electric parking brake system was proposed for the deficiencies of the manual parking brake system used currently, such as complicated operation, huge institution, elongation of the cable. This paper presented CAN communication interface circuit and application layer protocol definition of CAN bus, achieved intelligent control for the left and right rear wheel integration using the proposed control strategy. The system can reduce the difficulty of the drivers operation and improve driving comfort and safety.%针对目前使用的手动驻车制动系统操作繁琐、机构庞大、钢索容易变形伸长等不足,提出了基于CAN总线的电子驻车制动系统的模块化设计方案,详细介绍了电子驻车制动控制系统的CAN通讯接口电路及CAN总线应用层协议的定义,实现了对左、右后车轮一体化执行机构的智能化控制.该系统可以降低驾驶员的操作难度,提高驾驶的舒适性、安全性.
