Abstract
PURPOSE: To prevent stop failure of an engine for the time of closing a throttle valve when speed of the engine is controlled to target speed at the time of idling operation, by suspending control operation to the target speed when a speed change rate of the engine is not smaller than a prescribed value.
CONSTITUTION: A circuit 13 for detecting a change rate of engine speed is provided in a control unit 9 that controls an idling state in an engine 1. If the operator opens a throttle within the range of closing for a throttle full open switch 8, speed 7a of the engine rapidly rises, and output 13a of a detecting circuit 13 becomes 1 then output 14a of a flip flop 14 becomes 1. This output is input to an actuator driving circuit 12a, and a signal 6a for driving an actuator that controls an air control valve 5 is not output.
