The invention provides a steering wheel turning angle correction method and system, a storage medium and a vehicle, and belongs to the technical field of vehicles, and the steering wheel turning angle correction method comprises the steps that based on the rotating speeds of multiple wheels at the current moment and the wheel tread of the vehicle, the turning radiuses of the multiple wheels at the current moment are determined; based on the turning radiuses of the multiple wheels at the current moment, an estimated turning angle of the steering wheel at the current moment is determined; and based on the estimated rotation angle at the current moment and the collection rotation angle of the sensor at the current moment, correcting the collection rotation angle of the sensor after the current moment. The estimated turning angle of the steering wheel is reversely derived through the turning radius of the wheel, so that the acquired turning angle is corrected based on the estimated turning angle to obtain the actual turning angle, the difference between the actual turning angle determined by the vehicle and the real steering intention of a driver is eliminated, and the technical effect of improving the vehicle steering control accuracy is finally achieved.

    本申请提供了一种方向盘转角修正方法、系统、存储介质及车辆,属于车辆技术领域,方向盘转角修正方法包括:基于多个所述车轮在当前时刻的转速以及车辆的轮距,分别确定多个所述车轮在所述当前时刻的转弯半径;基于多个所述车轮在当前时刻的转弯半径,确定所述方向盘在所述当前时刻的估算转角;基于所述当前时刻的估算转角以及所述传感器在所述当前时刻的采集转角,对所述传感器在所述当前时刻之后的采集转角进行修正。本申请通过车轮的转弯半径反推出方向盘的估算转角,从而再基于估算转角对采集转角进行修正得到实际转角,进而消除车辆确定出的实际转角与驾驶员真实转向意图之间的差异,最终实现提高车辆转向控制准确度的技术效果。
