Abstract:
A throttle control apparatus includes a valve. A motor is provided for generating driving force to rotate the valve. Gears transmit the driving force to the valve. A biasing unit generates biasing force to bias the valve in a close rotative direction. A control unit is provided for supplying electricity to the motor to generate the driving force. When the control unit terminates electricity supply to the motor, the valve is biased to a full close position by the biasing force. When the control unit performs a full close control to manipulate the valve toward the full close position, the control unit continues electricity supply to the motor to stop the valve at a full close control point, which is set in advance of the full close position.
