The embodiment of the invention provides a torque distribution method and device, a first optimal torque distribution diagram establishing method, a second optimal torque distribution diagram establishing method, electronic equipment, a vehicle power system and a vehicle. The torque distribution method comprises the steps that of obtaining the required torque of the vehicle; determining a torque distribution standard according to the required torque and the reference torque; and according to the torque distribution standard, distributing the corresponding first sub-torque and second sub-torqueto a first motor and a second motor correspondingly. According to the scheme of the embodiment of the invention, when the relationship between the required torque and the reference torque is different, different torque distribution standards can be determined, so that the two motors can work in the optimal state under different required torques, the efficiency of the system is improved, the energy conversion efficiency of the whole vehicle is improved, and the economy of the whole vehicle is improved.

    本申请实施例提供一种扭矩分配方法、装置、第一、第二最优扭矩分配图的建立方法、电子设备、车辆动力系统和车辆。其中,扭矩分配方法,包括:获取车辆的需求扭矩;根据需求扭矩和参考扭矩,确定扭矩分配标准;根据扭矩分配标准,向第一电机和第二电机分别分配对应的第一子扭矩和第二子扭矩。本申请实施例的方案,当需求扭矩和参考扭矩的关系不同时,可以确定不同的扭矩分配标准,从而,可以保证两个电机在不同的需求扭矩下均工作在最优状态,提高了系统的效率,提高了整车能量转换效率,提高了整车的经济性。
