The invention discloses a vehicle and a deviation control method thereof, a storage medium and an electric power steering system. The vehicle deviation control method comprises the steps that state information and basic assisting torque of a vehicle are obtained, and the state information comprises steering torque of the vehicle; when it is determined that the state information meets the preset deviation compensation requirement, the deviation compensation torque of the vehicle is calculated according to the basic assistance torque and the steering torque; and controlling a power-assisted motor of a vehicle steering system according to the deviation compensation torque and the basic power-assisted torque of the vehicle so as to enable the vehicle to run linearly. Therefore, according to the vehicle deviation control method, the vehicle state information is monitored in real time in the vehicle running process, and the corresponding compensation torque is calculated according to the steering torque and the basic torque, so that it is guaranteed that the vehicle can still run in a straight line under different working conditions, the universality of vehicle deviation compensation is improved, and the service life of the vehicle is prolonged. Meanwhile, the driving texture of the vehicle is improved, the burden of a driver is relieved, and the driving safety and comfort of the vehicle are guaranteed.

    本发明公开了一种车辆及其跑偏控制方法、存储介质及电助力转向系统。其中,车辆跑偏控制方法包括:获取车辆的状态信息和基本助力力矩,其中,状态信息包括车辆的转向力矩;在确定状态信息满足预设跑偏补偿要求时,根据基本助力力矩和转向力矩计算车辆的跑偏补偿力矩;根据车辆的跑偏补偿力矩和基本助力力矩对车辆转向系统的助力电机进行控制,以使车辆直线行驶。由此,该车辆跑偏控制方法通过在车辆行驶过程中实时对车辆状态信息的监测,根据转向力矩和基本力矩计算出相应的补偿力矩,以此保证车辆在不同的工况下仍能保持直线行驶,提高了车辆跑偏补偿的通用性,同时提升车辆的行驶质感并减轻驾驶员的负担,保证车辆行驶的安全性和舒适性。
