Abstract
There is provided a throttle control system and method for an internal combustion engine as well as an engine control unit, which are capable of controlling a throttle valve without any trouble even when the throttle valve is frozen. The throttle control system controls the degree of opening of the throttle valve. The opening of the throttle valve detected during control of the throttle valve to a fully-closed position at a start of the engine is set to a smallest angle. A temperature of the throttle valve is detected. A lower limit value of the target degree of opening is set to a degree of opening larger than the detected smallest angle of the throttle valve, when the detected smallest angle is larger than a predetermined degree of opening and at the same time the detected temperature of the throttle valve is lower than a predetermined temperature.
