The invention discloses a torque correction method and device, a computer readable storage medium and a product, and relates to the technical field of automobiles, and the method comprises the following steps: obtaining a target torque and an actual torque of an engine; obtaining a difference value between the target torque and the actual torque equivalent; and according to the difference value, the friction torque of the engine is updated, and the actual torque of the engine is updated according to the updated friction torque, so that the target torque of the engine is basically the same as the actual torque. The actual torque of the engine can be basically the same as the target torque, the difference value between the target torque and the actual torque equivalent, namely the scatter difference between the actual torque and the target torque, is compensated into the friction torque, the actual torque is updated again, the actual torque of the engine can be closer to the target torque, and the engine reliability is improved. Therefore, the influence of scattered difference on the torque of the hybrid vehicle is reduced, and the conditions of feed and runaway are reduced.

    本申请公开了扭矩修正方法及装置、计算机可读存储介质及产品,涉及汽车技术领域,包括以下步骤:获取发动机的目标扭矩与实际扭矩;获取目标扭矩与实际扭矩当量的差值;根据差值,更新发动机的摩擦扭矩,并根据更新后的摩擦扭矩更新发动机的实际扭矩,以使得发动机的目标扭矩与实际扭矩基本相同。可以使得发动机的实际扭矩与目标扭矩基本相同,将目标扭矩与实际扭矩当量的差值,也即实际扭矩与目标扭矩的散差,补偿到摩擦扭矩中,重新更新实际扭矩,可以使得发动机的实际扭矩与目标扭矩更为接近,从而减少散差对混动车辆扭矩的影响,减少馈电和跑飞的情况。
