  • Gear control system and method
    Patent number: 8370035
    Abstract: A gear control system includes a pulse modulating circuit, a motor, and a central processing unit operatively coupled to the pulse modulating circuit and configured to control rotation of the motor from an original gear position to a desired gear position via the pulse modulating circuit. A motor position detecting device is operatively coupled to the central processing unit and detects the motor rotation position and transmits the motor position information corresponding to the motor rotation position to the central processing unit. The central processing unit determines whether the motor has reached the desired gear position based on the motor position information, and actuates the pulse modulating circuit to transmit pulses to actuate the motor to reach the desired gear position when the motor has not reached the desired gear position.
