Abstract
A method for clutch disengagement at idling running of a vehicle including an automated manual transmission is characterized in that a rate of the clutch disengagement is controlled responsive to a brake pedal force applied to a brake pedal by a vehicle operator. A clutch disengagement controller controls a rate of clutch disengagement at engine idling running mode. The clutch disengagement controller is connected to a brake pedal sensor sensing a force applied to a brake pedal and to at least one air inlet valve controlling a position of a clutch cylinder. The controller controls opening of said at least one air inlet valve responsive to the force sensed by the brake pedal sensor.
