The invention discloses a vehicle steering control method, a vehicle steering system and a vehicle, the vehicle comprises a distributed driving system, and the vehicle steering control method comprises the steps that according to a steering wheel target steering angle and a steering wheel actual steering angle, a steering wheel steering angle error is determined; determining a target differential torque of a steering wheel according to the steering wheel angle error; and according to the target differential torque of the steering wheel, a driving motor corresponding to the steering wheel in the distributed driving system is controlled, so that the target differential torque of the steering wheel is distributed to the steering wheel. According to the method and the system, the problem of inaccurate steering possibly caused by a fault of a vehicle steering system can be solved, additional hardware does not need to be added, the manufacturing cost is low, the vehicle structure and the control design are simple, and the occupied space is saved.

    本发明公开了一种车辆转向控制方法、车辆转向系统和车辆,其中,车辆包括分布式驱动系统,所述车辆转向控制方法包括:根据方向盘目标转角和方向盘实际转角,确定方向盘转角误差;根据所述方向盘转角误差确定转向轮目标差动力矩;根据所述转向轮目标差动力矩控制所述分布式驱动系统中对应转向轮的驱动电机,以将所述转向轮目标差动力矩分配至所述转向轮。本发明的方法和系统可以解决车辆转向系统在故障情况下可能导致的转向不准确的问题,并且无需增加额外硬件,制造成本低,车辆结构和控制设计简单,节省了占用空间。
