The invention provides a hybrid electric vehicle engine torque compensation method and device, and belongs to the technical field of hybrid power. When it is detected that a difference value exists between actual torque output by an engine at the current rotating speed and maximum theoretical torque, namely the output torque of the engine does not reach the expectation, the output of a driving motor is controlled to be increased in time, and the torque compensation effect is achieved. Therefore, the torque gap is compensated quickly and accurately, and the dynamic response of the whole vehicle is improved.

    本申请提供了一种混合动力汽车发动机扭矩补偿方法及装置,属于混合动力技术领域,当检测出发动机在当前转速下输出的实际扭矩和最大理论扭矩之间存在差值时,即发动机输出扭矩没有达到预期时,及时控制驱动电机的输出增加,从而快速准确地将扭矩缺口进行补偿,提高整车动力响应。
