The invention relates to the technical field of automobile control, in particular to a vehicle steering correction method and device, a vehicle and a storage medium, and the method comprises the following steps: obtaining a first rotation angle, an actual vehicle speed and an actual transverse acceleration of a steering wheel when the vehicle steers; according to the actual vehicle speed and the actual transverse acceleration, calculating a second rotation angle of a steering wheel when the vehicle steers, and calculating an angle difference value between the first rotation angle and the second rotation angle; when the angle difference value is larger than a correction threshold value, the rotation angle of the steering wheel and/or the steering wheel is corrected according to a correction value matched with the angle difference value till the angle difference value is smaller than or equal to the correction threshold value, and the error between the steering midpoint of the steering wheel and the steering midpoint of the steering wheel is kept within the preset expected error range. Therefore, the problems that when the steering midpoint of the steering wheel of the vehicle is inconsistent with the steering midpoint of the wheel, a traditional sensor measure is used for solving the problem, cost is high and the like are solved.
本申请涉及汽车控制技术领域,特别涉及一种车辆的转向矫正方法、装置、车辆及存储介质,其中,方法包括以下步骤:获取车辆转向时方向盘的第一转动角度、实际车速和实际横向加速度;根据实际车速和实际横向加速度计算车辆转向时转向轮的第二转动角度,并计算第一转动角度和第二转动角度之间的角度差值;在角度差值大于矫正阈值时,根据角度差值匹配的矫正值矫正方向盘和/或转向轮的转动角度,直到角度差值小于或等于矫正阈值,使得方向盘的转向中点与转向轮的转向中点之间的误差保持在预设期望误差范围内。由此,解决了当车辆的方向盘转向中点与车轮转向中点不一致,利用传统的传感器措施进行解决,成本较高等问题。
