ABSTRACT:
An engine idling control apparatus having an idle switch which turns on/off in response to the open/close of a throttle valve and judging the idle state in accordance with the open/close operation of the idle switch. The idle switch state is judged by an idle switch state judging unit in accordance with the on/off the idle switch. When it is judged as the idle state, the max/min value of an output from a throttle valve sensor for detecting the opening degree of the throttle valve is detected by a max/min value detecting unit. A max/min value updating unit compares the detected max/min value with an already stored max/min value, and updates the already stored max/min value to store the updated max/min value. In accordance with the updated max/min value, a comparison reference value setting unit sets an idle judgement comparison reference value which is compared by an idle state judging unit with an output from the throttle valve sensor to judge if the engine is in an idle state or not. The idle switch is arranged to be turned on/off at the point where the throttle valve is opened slightly from its fully closed state.
