The invention provides a steering wheel corner neutral position calibration method and device, a storage medium and a vehicle, after a steering wheel corner neutral position calibration signal is responded, whether the actual driving direction of the vehicle is the linear direction or not is judged, and if the actual driving direction of the vehicle is the linear direction, it is indicated that the steering wheel deflection angle is the neutral position at the moment; under the situation that the front wheel deflection angle corresponds to the steering wheel middle position, the position of a road feeling simulator motor rotor at the current moment is obtained to serve as a road feeling simulator motor calibration value corresponding to the steering wheel middle position; and the position of a motor rotor of the steering actuator at the current moment is obtained to serve as a steering actuator motor calibration value corresponding to the neutral position of the steering wheel, then the road feeling simulator motor calibration value is sent to the road feeling simulator, and the steering actuator motor calibration value is sent to the steering actuator. The scheme does not need to be carried out on a vehicle production line and can be carried out at any time in the vehicle running process, vehicle machining procedures are reduced, and the vehicle production energy efficiency is improved.

    本申请提供一种方向盘转角中位标定方法、装置、存储介质及车辆,响应于方向盘转角中位标定信号后,判断车辆实际行驶方向是否为直线方向,如果车辆实际行驶方向为直线方向,说明此时方向盘偏转角度为中位,且前轮偏转角度也对应于方向盘中位的情形,在此情形下,获取当前时刻的路感模拟器电机转子位置作为与方向盘中位对应的路感模拟器电机标定值,获取当前时刻的转向执行器电机转子位置作为与方向盘中位对应的转向执行器电机标定值,之后将路感模拟器电机标定值发送至路感模拟器,将转向执行器电机标定值发送至转向执行器。本方案无需在车辆生产线进行,能够在车辆行驶过程中随时执行,减少了车辆加工工序提高了车辆生产能效。
