The invention discloses a vehicle and a steering-by-wire system front wheel drive control method and device thereof. The control method comprises the steps of obtaining real-time vehicle state parameters and a real-time steering angle request of a driver; determining a front wheel reference turning angle according to the real-time vehicle state parameter and the real-time turning angle request; determining a front wheel compensation rotation angle according to the real-time vehicle state parameters; determining a steering execution target steering angle according to the front wheel reference steering angle and the front wheel compensation steering angle; and driving a front wheel motor of the vehicle to act according to the steering execution target turning angle. Compensation control is carried out on front wheel steering according to the steering angle request of the driver and the vehicle state data, the control stability of the vehicle is improved, and the driving experience is improved.

    本发明公开了一种车辆及其线控转向系统前轮驱动控制方法、装置,该控制方法包括:获取实时车辆状态参数和驾驶员的实时转角请求;根据实时车辆状态参数和实时转角请求确定前轮基准转角;根据实时车辆状态参数确定前轮补偿转角;根据前轮基准转角和前轮补偿转角确定转向执行目标转角;根据所述转向执行目标转角驱动车辆的前轮电机动作。本发明根据驾驶员的转角请求和车辆状态数据对前轮转向进行补偿控制,有利于提升车辆的操纵稳定性,提升驾驶体验。
