Electronic throttle control apparatus

An electronic throttle control apparatus, comprising:

• a throttle opening degree sensor that detects an opening degree position of a throttle valve which opens and closes to adjust an amount of air sucked into an engine;
• a throttle actuator including a motor, the throttle actuator being for opening and closing the throttle valve by energization of the motor;
• a first target opening degree position setting means that sets a first target opening degree position of the throttle valve in response to a signal from a control means of the engine;
• a throttle opening degree feedback control means that receives an input of the opening degree position detected by the throttle opening degree sensor and an input of the first target opening degree position from the first target opening degree position setting means to perform feedback control on the throttle valve to match the opening degree position and the first target opening degree position with each other;
• a throttle valve full-close position judgment means that judges 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 means that sets a second target opening degree position obtained by adding a first predetermined opening degree to a detected full-close position detected by the throttle opening degree sensor when the throttle valve full-close position judgment means judges that the throttle valve is being urged in the direction to be closed at the full-close position;
• and
• a target opening degree position switching means that receives an input of the first target opening degree position from the first target opening degree position setting means and an input of the second target opening degree position from the second target opening degree position setting means to switch a signal to be input to the throttle opening degree feedback control means from the first target opening degree position to the second target opening degree position,
• wherein, when the throttle valve full-close position judgment means judges that the throttle valve is being urged in the direction to be closed at the full-close position, the throttle opening degree feedback control means performs the feedback control on the throttle valve to match the opening degree position and the second target opening degree position with each other by the target opening degree position switching means.
