摘要： A throttle valve controller for an internal combustion engine has a throttle valve driven by a motor. The target opening of the throttle valve is determined based on the operating state of the vehicle or internal combustion engine. A first lower limit is determined beforehand as the minimum target opening, and a second lower limit is set which is smaller than the first lower limit if the determined target opening is smaller than a predetermined opening and/or if the rotation speed of the internal combustion engine is lower than a predetermined speed.

摘要： If a throttle valve is moved toward the mechanical full close position at high speed, the throttle valve may overshoot and collide against the full close position. This may damage and deform the throttle valve. It is an object of the present invention to set a lower limiter to the throttle valve so as to secure a margin to prevent such collision while attaining lowered fuel consumption or improved fuel efficiency.The above-mentioned object is attained by a throttle valve controller for an internal combustion engine, which comprises: a throttle valve which is driven by a motor; means for determining the target opening of the throttle valve based on the operating state of the vehicle or internal combustion engine; a first lower limit which is determined beforehand as the minimum target opening; and means for setting a second lower limit which is smaller than the first lower limit if the determined target opening is smaller than a predetermined opening and/or if the rotation speed of the internal combustion engine is lower than a predetermined speed.
