Zusammenfassung:The invention relates to a method for control of a power train, comprising an engine, a clutch function and a gearbox, and a service brake system in a vehicle. When the vehicle's clutch function is detected as being in an open state, the vehicle's gearbox is detected as being in a state which indicates a direction of movement, and accelerator pedal depression is detected, it is decided whether the vehicle is rolling in an opposite direction to that indicated by the gearbox state detected. If the vehicle is found to be rolling in an opposite direction to that indicated by the gearbox state detected, the vehicle's service brakes are applied instead to initiate a slide-in process for the clutch function. Using the wheel brakes instead of going through a slide-in process for the clutch function during a braking phase reduces wear and thermal stress on the clutch function.
