摘　　要：为了解决传统汽车中组合开关线束复杂、价格昂贵的问题,设计并搭建了一个基于无线局域网络的电气机构控制系统。选用车载电脑为人车交互窗口来完成人车对话,以新力维无线模块WM001S为载体实现无线控制信号与汽车CAN总线的连接,这样就实现了控制开关与汽车ECU的通信。再通过ECU来实现对电气机构的控制,从而达到了借助无线网络来控制汽车电气机构的目的。实验结果证明,该系统最大响应时间为200ms、操作简单、工作稳定可靠、大大降低了线束的复杂程度以及布置线束的空间要求。In order to simplify the harness of the combination switch,and reduce the cost about automobile-manufacturing,a system was designed and built to control the auto electrical mechanism,which was based on wireless network.Taking the board computer as the window to make sure the communication go with a swing between the vehicle and the driver,with the wireless module which was called Seanywell-WM001S as the carrier to implement the wireless control signal connect with the CAN bus successfully,then the communication between the control signal and the vehicle ECU was set up,at the last via the ECU to accomplish the control function of the electrical mechanism,of course,the communication between the switch and ECU was come true.As the auto electrical mechanism were under the control of the ECU,so the purpose that via wireless network to control the electrical mechanism was achieved.Test results proved that the maximal response time of the system is 200ms,in addition,the system is easy to operate and has high reliability,greatly reduce the complexity of the harness and the difficulty to allot the space for the harness.
