The invention discloses a control method, device and equipment for inhibiting engine shaking, which are used for counteracting torque fluctuation generated in the starting and stopping process of an engine and improving the driving smoothness. The method comprises the steps that in response to an engine starting or stopping instruction, the rotating speed difference value of a driving motor and a gearbox input shaft is determined; subtracting the rotating speed difference value of the driving motor and the gearbox input shaft at the previous moment from the rotating speed difference value of the driving motor and the gearbox input shaft at the current moment to obtain the rotating speed difference value change rate of the driving motor and the gearbox input shaft; determining a torque compensation value of the driving motor according to the rotating speed difference value of the driving motor and the gearbox input shaft and the rotating speed difference value change rate of the driving motor and the gearbox input shaft at the current moment; and the torque compensation value is compensated for the driving motor to restrain engine shaking.

    本申请公开了一种抑制发动机抖动的控制方法、装置及设备,用于抵消发动机启停过程产生的扭矩波动,提高驾驶平顺性。该方法包括:响应于发动机启动或停机指令,确定驱动电机与变速箱输入轴转速差值;将当前时刻的驱动电机与变速箱输入轴转速差值减去上一时刻的驱动电机与变速箱输入轴转速差值,得到驱动电机与变速箱输入轴转速差值变化率;根据当前时刻的驱动电机与变速箱输入轴转速差值以及驱动电机与变速箱输入轴转速差值变化率,确定驱动电机的扭矩补偿值;将扭矩补偿值补偿给驱动电机,以抑制发动机抖动。
