Automatic transmission brushless motor control checking method

The invention discloses an automatic transmission brushless motor control checking method, which is used for checking an output result of an automatic transmission brushless motor control system, and comprises the following steps: S1, a brushless motor ground end wire harness is additionally provided with a current sensor to collect motor consumption current; s2, a shaft and tooth increasing rotating speed sensor connected with the brushless motor collects the output rotating speed of the motor; s3, comparing the consumed current with the output rotating speed, and correcting the current control of the TCU on the motor; and S4, comparing the consumed current, the output rotating speed and the three-phase rotor position, and carrying out troubleshooting on the motor control system. Whether a control system of the brushless motor operates well or not is verified through data analysis of feedback current and output rotating speed of the brushless motor of the automatic transmission. 本发明公开了一种自动变速器无刷电机控制校核方法，利用所述校
