Abstract
An electronic throttle control apparatus includes: a motor; a throttle valve which is driven by the motor to open and close; a throttle sensor for detecting an actual opening angle of the throttle valve. This electronic throttle control apparatus is arranged to control an opening angle of the throttle valve by driving the motor so that the actual opening angle detected by the throttle sensor becomes a target opening angle, the apparatus further includes a fully closing stopper, and an abutting determination unit for determining whether the throttle valve abuts against the fully closing stopper. The abutting determination unit is arranged to determine whether the throttle valve abuts against the fully closing stopper based on a determination condition preset with respect to each one of a plurality of duty ratio ranges.
