The invention provides a vehicle EPS neutral position self-learning method and system, a storage medium and a computer. The method comprises the steps that whether a driver has a steering state or not is judged based on steering wheel information of a vehicle; if the driver does not have the steering intention and the duration time exceeds a first threshold value, the output torque of an EPS motor of the vehicle is compared with a preset output torque threshold value; if the output torque is in a preset output torque threshold value and the duration exceeds a first threshold value, the current driving state of the vehicle is determined based on the output torque; if the current driving state of the vehicle is a straight driving state, comparing the system neutral position data in the EPS motor with the initial neutral position data of the vehicle; if the system meso-position data is not equal to the initial meso-position data of the vehicle, the current vehicle speed of the vehicle is compared with a preset vehicle speed threshold value; and if the current vehicle speed is within the preset vehicle speed threshold value and the duration exceeds the first threshold value, carrying out median self-learning on the EPS motor based on the initial median data.

    本发明提供一种车辆EPS中位自学习方法、系统、存储介质及计算机,该方法包括:基于车辆的方向盘信息判断驾驶员是否存在转向状态;若驾驶员不存在转向意图、且持续时间超过第一阈值,将车辆的EPS电机的输出扭矩与预设输出扭矩阈值进行对比;若输出扭矩处于预设输出扭矩阈值、且持续时间超过第一阈值,基于输出扭矩确定车辆的当前行驶状态;若车辆的当前行驶状态处于直线行驶状态,将EPS电机中的系统中位数据与车辆的初始中位数据进行数据对比;若系统中位数据不等于车辆的初始中位数据,将车辆的当前车速与预设车速阈值进行对比;若当前车速处于预设车速阈值内、且持续时间超过第一阈值,基于初始中位数据对EPS电机进行中位自学习。
