Abstract

In a method of operating a drive device for a motor vehicle, a clutch is at least partly engaged, while an internal combustion engine of the drive device is inactive during coasting of the motor vehicle and the clutch is disengaged, to crank and thereby start the internal combustion engine with a clutch torque applied to the clutch. The clutch torque is hereby determined from a default wheel slip value which is based on a motor vehicle parameter.
