Engine speed control method and controller therefor

摘要

To prevent the actual engine speed under idling from excessively increasing or decreasing, an idling-up correction value for correcting an idling-engine-speed control air quantity is obtained as an idling-up correction value correlated with a radiator-fan driving duty (load value) determined by a cooling water-temperature sensor and a vehicle speed. Thereby, the engine speed Ne under idling is controlled.
