The invention discloses a starting and closing torque control system and method for an external control variable displacement compressor, and belongs to the technical field of variable displacement compressor control, the external control variable displacement compressor starting and stopping torque control system comprises an air conditioner controller, a sensor assembly, a compressor assembly, an air blower and an ECU, and the air conditioner controller is electrically connected with the sensor assembly, the compressor assembly, the air blower and the ECU. According to the starting and closing torque control system and method for the external control variable displacement compressor, by optimizing the control strategy of closing and opening of a compressor clutch and the control strategy of the compressor control current, through the time sequence and the change of the compressor control current, torque impact at the starting and closing moments is reduced. The engine can well respond to the torque compensation requirement, and air conditioner switching-on and switching-off transition is completed in a relatively stable rotating speed state.

    本发明公开了一种外控变排量压缩机开启关闭扭矩控制系统及方法,属于变排量压缩机控制技术领域,包括:空调控制器、传感器组件、压缩机组件、鼓风机和ECU,所述空调控制器分别与传感器组件、压缩机组件、鼓风机和ECU电性连接。本发明提供了一种外控变排量压缩机开启关闭扭矩控制系统及方法,通过优化压缩机离合器吸合和断开、压缩机控制电流的控制策略,通过时序和压缩机控制电流的变化,减小了开启和关闭瞬间的扭矩冲击,使发动机能够很好响应扭矩补偿需求,在相对平稳的转速状态完成开关空调的过渡。
