The invention relates to a vehicle torque distribution method and device, a storage medium and a vehicle, and relates to the technical field of vehicles. The method comprises the steps that a first target torque distributed to an engine is determined according to the running state of the engine and the first torque capable of being provided by the engine at present; and determining the torque which can be borne by the motor and exceeds the capacity of the engine according to the second torque which can be provided by the motor at present and the basic torque of the motor calculated according to the charge state of the power battery, and redistributing the torque exceeding the capacity of the motor to the engine. Therefore, the torque capable of being borne by the motor is adjusted through the motor basic torque calculated by combining the charge state of the power battery, the torque of the engine is redistributed, the load point of the engine is adjusted, the engine works in the optimal working point range, oil consumption of the whole vehicle is reduced, and the service life of the whole vehicle is prolonged. And the smoothness of the whole vehicle is improved.

    本公开涉及一种车辆扭矩分配方法、装置、存储介质以及车辆,涉及车辆技术领域,该方法通过发动机的运行状态以及发动机当前能够提供的第一扭矩,确定分配至发动机的第一目标扭矩,再根据电机的当前能够提供第二扭矩以及根据动力电池的荷电状态计算到的电机基础扭矩来确定电机能够承担的超出发动机能力的扭矩,并将超出电机能力的扭矩重新分配至发动机。从而通过结合动力电池的荷电状态计算到的电机基础扭矩对电机能够承担的扭矩进行调节,以对发动机的扭矩进行重新分配,从而对发动机的负载点进行调节,使得发动机工作在最佳工作点范围,从而降低整车的油耗,并提高整车的平顺性。
