The invention discloses a steering system corner neutral position compensation control method and device, a vehicle and a storage medium, and belongs to the technical field of vehicles. Correspondingly obtaining preset rotor meso-position information of the motor rotor according to the initial meso-position calibration information of the TAS sensor; when the vehicle is in the straight running state, a steering wheel neutral position reference value is obtained; according to the method, the position information of the rotor angle of the vehicle is obtained, after deviation judgment is conducted through the newly obtained steering wheel neutral position reference value, the position information of the rotor angle of the vehicle with the large deviation is calculated through the steering wheel neutral position reference value which meets the duration time condition and is subjected to self-learning, and then the high-precision target steering wheel angle value can be obtained. A more accurate target steering wheel angle value is provided, and the accuracy of vehicle deviation control, track planning of a parking function and the like can be improved. And meanwhile, the maintenance workload and the maintenance cost can be reduced, and a user can use conveniently. In addition, the error of correction compensation calculation can be reduced, and the calculation result is more accurate.
本发明公开了一种转向系统转角中位补偿控制方法、装置、车辆及存储介质,属于车辆技术领域。根据TAS传感器的初始中位标定信息对应得到电机转子的预设转子中位信息;并在车辆处于直行状态时,获取方向盘中位参考值;获取车辆转子转角位置信息,利用最新获取的方向盘中位参考值进行偏差判断后,对偏差较大的车辆转子转角位置信息通过利用符合持续时间条件的、经过自学习的方向盘中位参考值计算后,可得到高精确度的目标方向盘转角值。提供更精准的目标方向盘转角值,可提高车辆跑偏控制、泊车功能的轨迹规划等的精确度。同时,也能减少维修工作量和维修成本,便于用户使用。此外,还可以降低修正补偿计算的误差,使计算的结果更加精准。
