本文提出一种电动式扰流板功能控制系统方案,该系统由电动扰流板、升降机构、电机、电动扰流板控制模块、主机、后区域控制模块及中央运算单元组成。主机与后区域控制模块通过 CAN 总线实现信号通信,后区域控制模块与电动扰流板控制模块通过 LIN 总线完成信号交互,其中后区域控制模块主要承担信号转发功能。当用户在主机上点击电动扰流板开启或关闭开关时,主机向后区域控制模块发送对应的 CAN 指令信号,后区域控制模块将该信号通过 LIN 总线转发至电动扰流板控制模块;电动扰流板控制模块接收控制指令后,驱动电动扰流板电机执行动作,同时实时监控电机反馈的电流状态及霍尔信号变化。若电动扰流板在动作过程中遇到障碍物,电动扰流板控制模块会根据电机电流与霍尔信号判断是否触发防夹功能,从而避免发生夹伤事故。

This paper presents a functional control system scheme for an electric spoiler. The system consists of an electric spoiler, a lifting mechanism, a motor, an electric spoiler control module, a host, a rear area controller, and a central processing unit. The host and the rear area controller communicate via CAN bus signals, while the rear area controller and the electric spoiler control module interact through LIN bus, with the rear area controller mainly responsible for signal forwarding. When the user clicks the electric spoiler on or off switch on the host, the host sends the corresponding CAN command signal to the rear area controller, which forwards the signal to the electric spoiler control module via the LIN bus. After receiving the control command, the electric spoiler control module drives the electric spoiler motor to perform actions, and at the same time, it real-time monitors the current status and Hall signal changes fed back by the motor. If the electric spoiler encounters an obstacle during the action process, the electric spoiler control module will judge whether to trigger the anti-pinch function according to the motor current and Hall signal, so as to avoid pinching accidents.
