The invention relates to a vehicle and a wheel edge drive system and a wheel edge drive torque distributing method thereof. The number of drive shafts of the drive system is no less than two, vehicle internal space can be arranged more reasonably, the better dynamic property can be obtained, and the passenger carrying capacity and the climbing property are enhanced compared with those of a bus driven by a single motor; torque of the drive shafts can be distributed flexibly according to power needed by the vehicle, the high efficiency of the wheel edge drive system is obtained, and the power consumption of a power battery is saved to the greatest degree; the torque distribution between the shafts, the steering differential and other control modules are combined together to form a control method suitable for the multi-rear-shaft wheel edge drive system, energy optimization of the drive system and the functions of the advanced automobile electronic control systems such as an ASR, an ESP and an EBS can be achieved, and the whole vehicle can obtain a good balance in the aspects of the dynamic property, economy, comfort, safety and the like.
