The invention discloses a torque distribution method and device of a hybrid power vehicle, the vehicle and a storage medium. The method comprises the steps that a preset number of engine efficiency datum lines are determined based on an engine universal characteristic curve; when the vehicle is in the hybrid drive mode and the battery electric quantity is larger than first preset electric quantity, the target output torque of the engine is determined according to the position relation between the total torque of the power end and the engine efficiency datum line; the target output torque of the motor is determined according to the target output torque of the engine and the total torque of the power end, so that the working range of the engine can be adjusted in real time around a preset number of engine efficiency datum lines, and the engine efficiency datum lines are located in ideal efficient areas as much as possible; therefore, the situation that the torque of the engine is kept unchanged after being located in an efficient area is changed, and the fuel-saving capacity of the hybrid vehicle is improved.

    本发明公开了一种混合动力车辆的扭矩分配方法、装置、车辆及存储介质,所述方法包括:基于发动机万有特性曲线确定预设数量的发动机效率基准线;当所述车辆处于混合驱动模式且电池电量大于第一预设电量时,根据动力端的总扭矩与所述发动机效率基准线的位置关系确定所述发动机的目标输出扭矩;根据所述发动机的目标输出扭矩和所述动力端的总扭矩确定电机的目标输出扭矩,可以使发动机工作范围围绕预设数量的发动机效率基准线进行实时调整,尽可能多的处于理想高效区域,从而改变发动机扭矩处于高效区域后即维持不变的情况,提升混动车辆的节油能力。
