The invention discloses a steering angle control method and device of an electric power steering system and a vehicle, the method is applied to the technical field of vehicles, the system comprises a steering assembly, a torsion bar is connected between the steering assembly and a steering wheel, the steering wheel is arranged on the input end side of the torsion bar, and the steering assembly is arranged on the output end side of the torsion bar. The method comprises the steps of obtaining a current steering wheel rotation angle and a current torsion bar output end rotation angle; checking the current steering wheel rotation angle and the current torsion bar output end rotation angle; and determining a rotation angle control grade based on a verification result, and taking the current torsion bar output end rotation angle as a final current steering wheel rotation angle to perform rotation angle control. According to the method, the source of obtaining the steering wheel angle information by the electric power steering system is not single any more, and then automatic driving in the true sense can be achieved.

    本发明公开了一种电动助力转向系统的转角控制方法、控制装置和车辆,该方法应用于车辆技术领域,该系统包括转向总成,转向总成与方向盘之间连接有扭杆,且方向盘设于扭杆的输入端侧,转向总成设于扭杆的输出端侧,该方法包括:获取当前方向盘转角和当前扭杆输出端转角;对当前方向盘转角和当前扭杆输出端转角进行校验;基于校验结果确定转角控制等级,并将当前扭杆输出端转角作为最终的当前方向盘转角以进行转角控制。该方法能够使电动助力转向系统获取方向盘转角信息的来源不再单一,进而能够实现真正意义上的自动驾驶。
