The embodiment of the invention provides a clutch sliding friction fault judgment method, a control device, a vehicle and a computer program product, and the method comprises the steps: obtaining a rotating speed signal communication state between a driving motor and the control device and between an engine and the control device in the process that the vehicle is driven by hybrid power; the rotating speed signal communication state comprises a communication normal state and a communication abnormal state; based on the rotating speed signal communication state, target rotating speed parameters of the vehicle are obtained, and based on the target rotating speed parameters, the rotating speed difference between the driving end and the driven end of the clutch is determined; the target rotating speed parameters comprise any two of a generator rotating speed, a driving motor rotating speed, a wheel rotating speed and an engine rotating speed; and according to the magnitude relation between the rotating speed difference and a preset rotating speed difference threshold value, a sliding friction fault judgment result of the clutch is obtained. And the sliding friction fault of the clutch can be accurately identified under the condition of normal communication or abnormal communication.

    本申请实施例提供一种离合器滑摩故障判断方法、控制装置、车辆及计算机程序产品,所述方法包括:在所述车辆通过混合动力驱动行驶过程中,获取所述驱动电机及所述发动机与所述控制装置间的转速信号通信状态;所述转速信号通信状态包括通信正常状态和通信异常状态;基于所述转速信号通信状态,获取所述车辆的目标转速参数,并基于所述目标转速参数,确定所述离合器的主动端与从动端之间的转速差;所述目标转速参数包括发电机转速、驱动电机转速、车轮转速、以及发动机转速中的任意两种;根据所述转速差与预设转速差阈值间的大小关系,得到所述离合器的滑摩故障判定结果。无论在通信正常还是异常的情况下都能够实现准确识别离合器的滑摩故障。
