Method for operating an automated drive train of a motor vehicle and automated drive train

An automated drive train for a motor vehicle, the automated drive train comprising:

• a service brake,
• a drive machine,
• at least one drive axle,
• a clutch,
• a control unit,
• the control unit being designed, during actuation of the service brake to achieve standstill of the motor vehicle, to automatically disengage a drive connection, between the drive machine and the at least a drive axle of the motor vehicle, by disengaging the clutch, and, during release of the service brake, to automatically engage again the drive connection by engaging the clutch, and
• the control unit being also designed to determine a desired drive direction of the motor vehicle based on a selected gear step, to compare the desired drive direction with an actual drive direction during the release of the service brake, to increase a pressure at the clutch, according to a first modulation characteristic curve, when the desired drive direction matches the actual drive direction, and to increase the pressure at the clutch, according to a second modulation characteristic curve, when the desired drive direction is different than the actual drive direction.

An agriculture or municipal utility vehicle comprising:

• a drive train having a service brake,
• a drive machine,
• at least one drive axle,
• a clutch,
• a control unit,
• the control unit being designed, during actuation of the service brake to achieve standstill of the motor vehicle, to automatically disengage a drive connection between the drive machine and the at least a drive axle of the motor vehicle by disengaging the clutch, and, during a release of the service brake, to automatically engage again the drive connection by engaging the clutch,
