Abstract

A method of controlling a motor vehicle with an automated clutch is provided and includes the steps of: (a) detecting the vehicle speed, (b) detecting if the brake and/or the gas pedal is actuated, (c) detecting whether or not the engine is running, (d) disengaging the clutch if the engine is found to be running while the vehicle is found to be moving faster than a threshold speed, and if at the same time neither the brake nor the gas pedal is found to be actuated, and (e) subsequently re-engaging the clutch if the brake and/or gas pedal is found to be actuated. Prior to re-engaging the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that that the respective rpm-rates of the engine and the transmission are brought towards a closer agreement.
