The invention discloses a torque distribution method and device of a hybrid power vehicle and the hybrid power vehicle, and relates to the technical field of vehicle control, and the method comprises the steps: obtaining the current wheel end demand power, and generating a target power map based on the current wheel end demand power and a preset initial offset power characteristic value; according to the target power map, the preset generator efficiency map and the preset motor efficiency map, the theoretical optimal offset power and the theoretical optimal rotating speed of the engine are obtained; and according to the current wheel end demand power, the theoretical optimal offset power and the theoretical optimal rotating speed of the engine, torque distribution is conducted on the engine and the motor. On the premise that the wheel end requirement is met, torque distribution is carried out by considering the comprehensive efficiency of the engine, the driving motor and the generator, and the fuel consumption economy of vehicle operation can be improved.

    本申请公开了一种混动车辆的扭矩分配方法、装置及混动车辆,涉及车辆控制技术领域,该方法包括:获取当前轮端需求功率,并基于当前轮端需求功率以及预设初始偏移功率特征值生成目标功率map;根据目标功率map、预设发电机效率map以及预设电机效率map获得理论最优偏移功率以及发动机理论最优转速;根据当前轮端需求功率、理论最优偏移功率以及发动机理论最优转速分别对发动机以及电机进行扭矩分配。本申请能在满足轮端需求的前提下,考虑发动机、驱动电机、发电机的综合效率来进行扭矩分配,有利于提升车辆运行的油耗经济性。
