Abstract
A throttle valve control apparatus for an internal combustion engine curbs the degree of opening of a throttle valve in accordance with the state of a transmission connected to a crankshaft of the engine and/or the state of operation of the vehicle. Normally, the control apparatus controls the throttle valve opening amount to a target throttle opening amount that is set based on the amount of depression of an accelerator pedal and the engine revolution speed. When the transmission is in a neutral state or when the vehicle is in a stopped state, a target throttle opening amount is set independently of the engine revolution speed.
