Abstract
A system for controlling the idling speed of an internal combustion engine includes a rotational speed sensor for sensing the rotational speed of an engine, a determination unit for determining whether the engine is in an idling operation state, a memory for storing engine control variables corresponding to the rotational speed of the engine when the determination unit determines that the engine is in the idling operating state, and an engine output controller which, when the discrimination unit determines that the engine is in the idling operating state, reads engine control variable information out of the memory in accordance with the rotational speed sensed by the sensor, and controls the output of the engine in accordance with the information read. Control of engine speed is achieved merely by having the engine output controller read out the engine control variable information from the memory when the engine output is controlled.
