The invention discloses a crosswind power-assisted compensation method for a vehicle. The method comprises the following steps: acquiring state information of the vehicle; when it is judged that the vehicle meets the PDC compensation torque condition based on the state information of the vehicle, the expected yaw of a driver is obtained according to the steering wheel angle, the wheel speed signal and the lateral acceleration, and the PDC side wind compensation torque is obtained based on the expected yaw of the driver; after the maximum value of the PDC crosswind compensation torque is limited according to the current vehicle speed, the road surface inclination angle and the steering wheel angle, the limited PDC crosswind compensation torque is superposed on the basis of the basic assistance torque, and the final PDC crosswind compensation torque is obtained; and controlling a steering wheel of the vehicle based on the final PDC crosswind compensation torque to realize crosswind power-assisted compensation. According to the crosswind assisting power compensation method and device of the vehicle, the vehicle and the storage medium, it can be guaranteed that when the vehicle is driven on a curve, assisting power can be effectively provided by the steering wheel, and meanwhile the problem that when the steering wheel slips out of the hand, the vehicle can deviate immediately is solved.

    本发明公开了一种车辆的侧风助力补偿方法,包括:获取车辆的状态信息;基于车辆的状态信息判定车辆满足PDC补偿力矩的条件时,根据方向盘转角、轮速信号、侧向加速度获取驾驶员期望横摆,基于驾驶员期望横摆获取PDC侧风补偿力矩;根据当前车速、路面倾斜角度、方向盘角度限制PDC侧风补偿力矩的最大值后,在基础助力力矩的基础上叠加限制后的PDC侧风补偿力矩,以获取最终的PDC侧风补偿力矩;基于最终的PDC侧风补偿力矩控制车辆的方向盘实现侧风助力补偿。本发明提供的车辆的侧风助力补偿方法、装置、车辆、存储介质,能在车辆侧向干扰较大时,保证车辆在弯道行驶时方向盘能够有效的提供助力,同时也避免了方向盘脱手时,车辆会立即跑偏的问题。
