Abstract
A system for controlling a clutch in a heavy vehicle including an internal combustion engine and an automated mechanical transmission, where the engine is running, the clutch is engaged and the transmission is in neutral, including an electronic control unit adapted to receive a request to shut down the engine, to disengage the clutch of the transmission, and to shut down the engine, where the electronic control unit is adapted to reengage the clutch when the rotation of the engine and the rotation of the transmission input shaft is zero, and to actively slow down rotation of the transmission input shaft by the use of a brake device if the stop time for the transmission input shaft exceeds a predefined time interval. The advantage of the invention is that vibrations and noise are reduced during shut down of the engine.
