Abstract:
1. An electronically controlled throttle apparatus comprising: a throttle valve held rotatably in a throttle body, an actuator for driving said throttle valve, a return spring which gives a force to return said throttle valve in the full open direction, a throttle position sensor for detecting the opening of said throttle valve, and a throttle actuator control unit for driving said actuator based on the opening of said throttle valve detected by said throttle position sensor and a target opening, wherein said throttle actuator control unit is provided with a control means which controls said actuator, when EGR control or DPF control has ended, so that said throttle valve turns toward the pull open position in a longer period of time than the length of time in which said throttle valve is tuned toward the full open position by said return spring only.
