Throttle valve controller for internal combustion engine |
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. |
