Controlling a kupplungsfüllbefehls on the basis of the hydraulic states, the incoming clutch

a system and method for controlling a Kupplungsfullbefehls are created on the basis of the hydraulic state of an on-coming clutch. A vehicle includes a hydraulically actuated on-coming clutch, which is configured to be engaged during a shifting event of an operating mode of the vehicle to another. A controller is configured to generate a start time of a Kupplungsfullbefehl in such a way that the conclusion of Kupplungsfullbefehls is synchronized with an identified speed profile of the incoming clutch. The on-coming clutch defines a hydraulic state in real time when the Kupplungsfullbefehl is generated. The controller is configured to generate at least partly on the basis of the hydraulic state in real time of the incoming clutch an acceptable speed margin in real time for the on-coming clutch. The controller is configured to cancel the Kupplungsfullbefehl if a rotational speed in real time (an actual clutch slip speed or an actual clutch speed profile) of the incoming clutch outside of an acceptable speed margin is located in real time.
