The invention discloses a torque distribution method, device and equipment, and a storage medium. The method comprises the steps of determining a total torque required by a vehicle, wherein the totaltorque is equal to a sum of the torque required by a front axle and the torque required by a rear axle; according to rotating speeds of front and rear motors and the total torque, determining electricefficiency of the whole vehicle when front and rear axle torques are in different distribution proportions; and according to boundary values of the front and rear axle torques and the electric efficiency of the whole vehicle when the front and rear axle torques are in different distribution proportions, determining a target distribution proportion of the front and rear axle torques and distributing the torques to the front and rear axles according to the target distribution proportion. According to the technical scheme provided by the embodiment of the invention, on the basis of considering the boundary values of the front and rear torques, the distribution proportion of the front and rear axle torques is determined in combination with the electrical efficiency of the whole vehicle so that the electrical efficiency of the vehicle is improved, and a cruising ability and economic performance of the vehicle are further increased.

    本发明公开了一种扭矩分配方法、装置、设备和存储介质。其中,所述方法包括:确定车辆所需的总扭矩;所述总扭矩等于前轴所需的扭矩与后轴所需的扭矩之和;根据前后电机的转速以及所述总扭矩,确定前后轴扭矩在不同分配比例时整车的电效率;根据前后轴扭矩的边界值以及所述前后轴扭矩在不同分配比例时整车的电效率,确定所述前后轴扭矩的目标分配比例,用于通过所述目标分配比例为前后轴分配扭矩。本发明实施例提供的技术方案,在考虑前后扭矩的边界值的基础上,还结合整车的电效率来确定前后轴扭矩的分配比例,提高了车辆的电效率,进而提高了车辆的续航能力和经济性能。
