Abstract
An engine speed control apparatus includes speed and throttle sensors and an arithmetic unit which derives throttle values according to the difference between the desired speed and the actual speed. If part of the throttle operation loop becomes inoperative such that the desired throttle value differs from the actual throttle value by a given amount for a given time, a judgement circuit suspends the operation of the arithmetic unit until the throttle operation loop operates normally.
