Method and system for controlling electronic throttle control system

Abstract

A method for controlling an electronic throttle control (ETC) system, in which an electronic control unit (ECU) controls the ETC system using an air volume learning value containing information on a volume of air introduced into an engine for each opening degree of the ETC system according to carbon deposit of the ETC system, the method may include reading an air volume learning value used during a previous operation. The air volume learning value is compared to a preset learning value change reference value. Whether an operation condition of the engine satisfies a learning value change condition which is preset to change the air volume learning value, and whether the volume of air passing through the ETC system satisfies a preset learning-value-change-air-volume condition are determined. The air volume learning value used during the previous operation and stored in the ECU is substituted with a preset initial value of the air volume learning value.
