The invention relates to the technical field of vehicles, discloses a power-assisted steering motor control method and device, a controller, a vehicle and a medium, and aims at solving the technical problems that in a traditional scheme, error compensation of the non-shimmy problem can be brought, and the shimmy problem of a steering wheel cannot be effectively solved. The method comprises the following steps: acquiring steering wheel torque characteristic frequency; judging whether the steering wheel is subjected to unbalanced excitation of the shimmy excitation source or not; when it is judged that the steering wheel is subjected to unbalanced excitation of the shimmy excitation source, the compensation torque of a power-assisted steering motor is obtained according to the torque characteristic frequency of the steering wheel; and outputting the compensation torque to the power-assisted steering motor.

    本申请涉及车辆技术领域,公开了一种转向助力电机控制方法、装置、控制器、车辆及介质,以解决传统方案中,会带来非摆振问题的误补偿,无法有效地解决方向盘摆振问题的技术问题。方法部分包括:获取方向盘力矩特征频率;判断方向盘是否受到摆振激励源的非平衡激励;当判定所述方向盘受到摆振激励源的非平衡激励时,根据所述方向盘力矩特征频率获取转向助力电机的补偿力矩;将所述补偿力矩输出至所述转向助力电机。
