A method for controlling the warm-up idle speed of an internal combustion engine is described. This publication describes a method of adjusting the cross-sectional area of a bypass passage that bypasses a throttle valve during idling operation according to the rotation speed and temperature. Furthermore, instead of changing the cross-sectional area of the bypass passage in such an idle control device, a device is also known that adjusts the non-operating position of the throttle valve when the accelerator pedal is not activated.
