Patent ID: 8370035

Claim:
A gear control system, comprising: a pulse modulating circuit; a motor; 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 operatively coupled to the central processing unit and configured to detect a motor rotation position and transmit motor position information corresponding to the motor rotation position to the central processing unit; the motor position detecting device further including: a Hall-effect sensor; a Hall information collecting circuit operatively coupled to the Hall-effect sensor and to the central processing unit; wherein the Hall information collecting circuit is configured to generate Hall information by inducing the rotational position of the motor and transmitting Hall information to the Hall information collecting circuit; and wherein the Hall information collecting circuit is configured to collect the Hall information and transmit the Hall information to the central processing unit to permit the central processing unit to determine the rotation position of the motor using the Hall information; the central processing unit configured to determine whether the motor has reached the desired gear position based on the motor position information; the central processing unit configured to actuate 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.
