摘　　要：目前汽车上普遍采用的单电机雨刷系统是通过机械连接实现的雨刷臂同步摆动,这种结构具有占用空间大和故障时维修不便等缺点,采用的双电机雨刷系统克服了这些不足,同时还减小了系统的重量和机械噪音,但必须采用合理的方式解决双电机的运行同步问题。针对这一问题,设计了采用CAN(controller area network)总线的双电机同步控制雨刷系统控制器。搭建了控制器各部分的硬件电路,依据雨刷臂摆动过程中约束条件,建立了参考运行轨迹,并通过曲线拟合的方式将实验采集到的雨刷臂的位置信息绘制成实际运行轨迹。通过主从同步控制方式,采用CAN总线作为两侧控制器信息传递的通讯总线,解决了双电机的同步控制问题,并在实际车辆上进行了相关实验,且已投入使用。实验结果表明:采用CAN总线的双电机雨刷系统控制器能够实现雨刷臂同步稳定运行,并且能够对其参考运行轨迹进行密切跟踪。Single-motor wiper system through a mechanical connection to swing synchronously is widely used.This structure has the disadvantages such as large space occupation,inconvenient maintenance and so on. Dualmotor wiper system overcomes all these problems and reduces the system weight and mechanical noise,but reasonable solution of synchronous operation should be adopted. To solve this problem,this design adopted dualmotor synchronous control wiper system based on CAN（Controller Area Network） bus. The circuit of the controller was built and the reference trajectories of wiper arms were established according to the constraints of the swing process while the actual trajectory was drawn through fitting the collected position information. Based on the CAN bus,the dual-motor synchronous control was realized through master-slave synchronous control method. The results of experiments show that： dual-motor wiper system controller based on CAN bus could achieve synchronous operation of the wiper arms tracking those reference trajectories.
