The invention provides a steering wheel neutral position correction method, a medium and a vehicle, and relates to the technical field of electric power steering system control. Under the condition that the vehicle meets the offset detection condition, the multiple steering wheel angles are continuously collected, and the average offset of the steering wheel is determined based on the multiple steering wheel angles. And then, determining a target compensation amount corresponding to the current power-on and power-off period of the EPS controller based on the average offset. And finally, in the current power-on and power-off period, correcting the steering wheel neutral position deviation based on the target compensation amount. According to the method, the average offset is calculated by continuously collecting the multiple steering wheel angles, unnecessary compensation can be avoided, offset errors are reduced, and the accuracy of the steering wheel neutral position offset compensation amount is improved. Meanwhile, correction of the steering wheel middle position deviation is achieved step by step through fractional correction of a plurality of continuous power-on and power-off periods, so that power-assisted fluctuation caused by too large one-time compensation amount is prevented, and driving safety and smoothness are guaranteed.

    本申请提供了一种方向盘中位修正方法、介质及车辆,涉及电动助力转向系统控制技术领域。本申请通过在车辆满足偏移检测条件的情况下,连续采集多个方向盘角度,并基于多个方向盘角度,确定方向盘的平均偏移量。然后,基于平均偏移量确定EPS控制器的当前上下电周期对应的目标补偿量。最后,在当前上下电周期内,基于目标补偿量,对方向盘中位偏移进行修正。本申请通过连续采集多个方向盘角度计算平均偏移量,能够避免非必要补偿,并减小偏移误差,提高方向盘中位偏移补偿量的准确性。同时,通过连续多个上下电周期的分次修正,逐步实现对方向盘中位偏移的修正,以防止一次性补偿量过大带来的助力波动,保证驾驶的安全性与平顺性。
