Drive train having clutch activation for overcoming the backlash of the drive train before start-up

Abstract

A drive train for a motor vehicle, including a drive unit having a drive shaft and a transmission having a transmission input shaft and a plurality of gears, of which at least one is used as a starting gear for the motor vehicle, and having a friction clutch, which is arranged between the crankshaft and the transmission input shaft and is actuated in an automated manner. In order to prevent start-up noise caused by backlashes in the motor vehicle, a backlash present in the transmission is compensated by applying a small compensating torque set at the friction clutch to the transmission input shaft while the starting gear is engaged before start up.
