The invention provides a dual-motor torque control method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the total demand torque of a wheel end and an efficiency table of front and rear motors, setting a segmentation minimum unit of front and rear shaft torques, determining the distribution proportion of the front and rear shaft demand torques under the segmentation minimum unit, and obtaining the efficiency table of the front and rear motors; front motor rotating speed and rear motor rotating speed are respectively calculated through a current vehicle speed signal and a front and rear motor drive axle speed ratio, front and rear wheel end required torque is obtained according to front and rear shaft required torque and the front and rear motor drive axle speed ratio, front motor efficiency and rear motor efficiency are respectively obtained, and total power is obtained; and taking the minimum estimated value in the estimated values of the total power as target total power, obtaining a target distribution proportion corresponding to the target total power, and obtaining front and rear wheel end demand torques according to the target distribution proportion. According to the method, the target torque of the front and rear motors can be calculated based on the driving consumption minimum power and the braking recovery maximum power target, and the economical efficiency of the vehicle is improved.

    本申请提供了一种双电机转矩控制方法、装置、电子设备及存储介质,该方法包括:获取轮端的总需求扭矩以及前后电机的效率表,设定前后轴转矩的分割最小单位,确定在该分割最小单位下前后轴需求转矩的分配比例,通过当前车速信号和前后电机驱动桥速比,分别计算得到前电机转速和后电机转速,并根据前后轴需求转矩以及前后电机驱动桥速比,获取前后轮端需求转矩,分别获取前电机效率、后电机效率,求得总功率,并将总功率的预估值中最小的预估值作为目标总功率,并获取目标总功率下对应的目标分配比例,根据目标分配比例获取前后轮端需求转矩。本申请能够基于驱动消耗最小功率和制动回收最大功率目标,计算前后电机的目标转矩,提升车辆的经济性。
