A method () for exiting a sailing mode of a vehicle () is described. The vehicle () comprises a clutch unit () which is disengaged in order to decouple a driving shaft () of the vehicle () from a driven shaft () of the vehicle (), when the vehicle () is operated in the sailing mode. The method () comprises predicting () that a trigger for an exit of the sailing mode will occur, and initiating () the preparation of the clutch unit () for engagement, subject to predicting that a trigger for the exit of the sailing mode will occur. Furthermore, the method () comprises detecting () a trigger for the exit of the sailing mode, and adapting () a shaft speed () of the driving shaft (), subject to detecting a trigger for the exit of the sailing mode. In addition, the method () comprises engaging () the clutch unit (), subject to preparing the clutch unit () for engagement and subject to adapting the shaft speed (), in order to exit the sailing mode.

Method and system for exiting a sailing mode of a vehicle

A method and arrangement is provided for controlling a motor vehicle drive train equipped with at least one drive motor, a torque converter, an automatic transmission and at least one electronic drive control device. In the drive control device, a function module is implemented for carrying out a creep control. This creep control can be activated independently of a brake actuation, when the actual rotational speed of the driving motor is greater than a defined desired rotational speed of the driving motor, and when the actual rotational speed of the driving motor cannot be reduced because of at least one defined condition as the minimally possible rotational speed of the driving motor.
