The invention provides a motor zero position angle calibration method, a vehicle and a storage medium, the method is applied to the field of vehicles, and the method comprises the following steps: if an obtained control signal sent by a vehicle control unit is a calibration mode setting signal, reading a reserved bit value of the calibration mode setting signal, and if the reserved bit value is a preset calibration value, determining that the control signal is the preset calibration value; if yes, zero position angle calibration processing is conducted on the vehicle motor based on the calibration mode setting signal, a calibrated zero position angle is obtained, updating processing is conducted on the motor zero position angle based on the calibrated zero position angle, and the updated motor zero position angle is adopted to control operation of the vehicle motor. According to the method, after the calibration mode setting signal is received, whether the reserved bit value conforms to the preset calibration value or not is determined again, the idle reserved bit is adopted as the identification bit, the vehicle motor is prevented from entering the calibration mode mistakenly under the condition of signal interference, the accuracy of zero angle calibration is improved, and normal operation of the vehicle motor is further ensured.
本申请提供了一种电机零位角标定方法、车辆和存储介质,该方法应用于车辆领域,该方法包括:若获取到车辆控制单元发送的控制信号为标定模式设定信号则读取标定模式设定信号的保留位数值,若保留位数值为预设标定数值,则基于标定模式设定信号对车辆电机进行零位角标定处理,获得标定零位角,基于标定零位角对电机零位角进行更新处理,采用更新处理后的电机零位角控制车辆电机运行。该方法能够接收到标定模式设定信号后再次确定保留位数值是否符合预设标定数值,采用闲置保留位作为标识位避免了车辆电机在信号干扰的情况下错误进入标定模式,提高了零位角标定的准确性,进一步确保了车辆电机的正常运行。
