Abstract
A method for selectively coupling a motor to a drive train of a motor vehicle using a clutch having a first clutch part driven by the motor, a second clutch part associated with the drive train and an actuator, the method includes the steps of: accelerating the first clutch part while simultaneously activating the actuator during a first actuation phase without engaging the first and second clutch parts; suspending activation of the actuator until a predefined rotational speed difference is reached between the first and second clutch parts; and engaging the first and second clutch parts during a second actuation phase upon reaching the predefined speed difference.
