Abstract:
A device for controlling the amount of the air taken in by an engine comprising:a throttle valve provided in the intake pipe of the engine for adjusting the amount of the air taken in by said engine;a throttle opening degree detection means for detecting the opening degree of said throttle valve as a throttle opening degree;an accelerator opening degree detection means for detecting the opening degree of the accelerator pedal as an accelerator opening degree;an idle detection means for producing an idle signal that corresponds to the fully closed position of said accelerator pedal;a throttle control means for operating a target throttle opening degree of said throttle valve based on said throttle opening degree, said accelerator opening degree and said idle signal; anda throttle actuator for opening and closing said throttle valve so that said throttle opening degree comes into agreement with said target throttle opening degree;wherein said throttle control means includes:a first opening degree operation means for operating a first target throttle opening degree based on said accelerator opening degree;a second opening degree operation means for operating a second target throttle opening degree based on said idle signal; anda target throttle opening degree operation means for operating said target throttle opening degree by adding up said first and second target throttle opening degrees together.
