The invention is applicable to the technical field of hybrid electric vehicles, and provides a torque control method and terminal equipment in an upshift process, and the method comprises the following steps: determining a quick drop torque required to be reduced by a P2 motor and an engine crankshaft end torque in a DCT upshift process; controlling the P2 motor to respond to torque reduction, and determining equipment which preferentially reaches the torque reduction limit in the P2 motor and the K0 clutch; according to the torque reduction limit and the quick-drop torque, calculating to obtain a residual quick-drop torque; and controlling the residual fast drop torque to respond from equipment which the torque drop limit preferentially reaches and/or equipment which does not reach the corresponding torque drop limit, so that the rotating speeds of the P2 motor and the engine are consistent with the rotating speed of the DCT input shaft, and further preventing over-temperature damage caused by overload of the K0 clutch.

    本发明适用于混合动力汽车技术领域,提供了一种升档过程中扭矩控制的方法及终端设备,该方法包括:确定DCT升档过程中P2电机与发动机曲轴端扭矩需降低的快降扭矩;控制所述P2电机响应降扭,并确定所述P2电机和所述K0离合器中降扭极限优先达到的设备;根据所述降扭极限以及所述快降扭矩,计算得到剩余快降扭矩;控制所述剩余快降扭矩由降扭极限优先达到的设备和/或未达到对应降扭极限的设备响应,使P2电机与发动机的转速与DCT输入轴的转速一致,进而防止K0离合器过载导致的过温损坏。
