Abstract
It is an object of the present invention to provide a controlling apparatus for throttle valve that detects a throttle open degree enabling more appropriate controls by removing ill effects of multiplexing an idle control in controlling data. The idle control amount is canceled by subtracting the idle target open degree from the detected throttle open degree. Further, in order to correct differences of the detected data due to a response delay of the throttle valve, the previous measured value is regarded as the detected throttle open degree when the response delay occurs.
