The invention provides a vehicle and a torque distribution method and device thereof. The method comprises the steps: acquiring the total torque demand of the whole vehicle, and acquiring the rotatingspeed of each motor; according to the total torque demand and the rotating speed of each motor, determining a torque distribution coefficient through a preset corresponding relation for indicating the total torque demand and the corresponding relation between the rotating speed of each motor and the torque distribution coefficient; and distributing the total torque demand according to the torquedistribution coefficient to determine the torque distributed to a first motor and the torque distributed to a second motor. Therefore, the overall operation efficiency of the system can be effectivelyimproved, the energy consumption of the system is reduced; meanwhile, the overall operation economy of the whole vehicle is ensured.

    本发明提出一种车辆及其扭矩分配方法和装置,其中,方法包括:获取整车总扭矩需求,并获取每个电机的转速;根据总扭矩需求和每个电机的转速,通过预先设定的对应关系确定扭矩分配系数,其中,对应关系用于指示总扭矩需求和电机的转速与扭矩分配系数的对应关系;根据扭矩分配系数对总扭矩需求进行分配,以确定分配至第一电机的扭矩以及分配至第二电机的扭矩,由此,可有效提高系统总体运行的效率,降低系统能耗,同时确保整车总体运行的经济性。
