Abstract
In order to obtain an electronic throttle control apparatus capable of forcibly turning a throttle valve from a full-close position toward an opening side by a predetermined opening degree to place the throttle valve in a desired opening degree position, the electronic throttle control apparatus includes: a throttle opening degree sensor for detecting an opening degree position of a throttle valve; a throttle actuator that opens and closes the throttle valve; a first target opening degree position setting unit for setting a first target opening degree position; throttle opening degree feedback control unit that performs feedback control on the throttle valve; a throttle valve full-close position judgment unit for judging whether or not the throttle valve is being urged in a direction to be closed at a full-close position; a second target opening degree position setting unit for setting a second target opening degree position; and a target opening degree position switching unit that switches a signal to be input to the throttle opening degree feedback control unit from the first target opening degree position to the second target opening degree position.
