AI Technical Summary
In existing AMT automatic transmissions, the shift motor drive control is inaccurate during gear shifting, resulting in insufficient precision in gear shifting operations.
By acquiring the current angular position signal value and the arrangement order of the angular position signal values of the shift drive motor rotor, the timing point for switching the stator energizing mode of the shift motor is determined, and the energizing mode of the motor stator is precisely switched. Combined with angular position and speed control, the precise rotation of the motor rotor is achieved.
It improves the accuracy of motor drive control and the precision of gear shifting operation, simplifies the processing flow, and ensures fast and reliable switching of motor stator energization mode.
