The invention provides a double-electric-drive-axle automobile torque distribution method, device and equipment and a readable storage medium. The method comprises the steps that the driving state of the automobile is determined based on the absolute value of the rotating speed difference value between an intermediate axle motor and a rear axle motor, a constant speed cruise switching signal, the absolute value of the first wheel speed difference value between front wheels and the absolute value of the second wheel speed difference value between rear wheels; comparing the judgment factor corresponding to the driving state with a threshold value corresponding to the driving state to obtain a comparison result; and distributing the torque of the middle axle motor and the torque of the rear axle motor based on a torque distribution strategy corresponding to the comparison result. According to the method, the driving state of the automobile is determined firstly, then the torque of the middle axle motor and the torque of the rear axle motor are distributed according to the torque distribution strategy corresponding to the comparison result in the driving state, and the purpose of reasonably distributing the torque of the front axle motor and the torque of the rear axle motor in different driving states of the automobile can be achieved.

    本发明提供一种双电驱桥汽车扭矩分配方法、装置、设备及可读存储介质。该方法包括:基于中桥电机与后桥电机之间的转速差值绝对值、定速巡航开关信号、前轮之间的第一轮速差值绝对值以及后轮之间的第二轮速差值绝对值确定汽车所处的行驶状态;将所述行驶状态对应的判断因子与所述行驶状态对应的阈值进行比对,得到比对结果;基于所述比对结果对应的扭矩分配策略对中桥电机和后桥电机的扭矩进行分配。通过本发明,先确定汽车所处的行驶状态,再基于该行驶状态下的比对结果对应的扭矩分配策略对中桥电机和后桥电机的扭矩进行分配,即可实现对车辆不同行驶状态下的前轴电机和后轴电机的扭矩进行合理分配的目的。
