Abstract:
1. A method of controlling an automated multi-step shift transmission arranged in a drivetrain of a motor vehicle in the force flow between a drive motor and an axle drive of either a drive axle or a transfer box, the method comprising the steps of: determining a current road inclination (NFB); after driving onto a downhill stretch, carrying out a shift to a lower gear to increase braking action of at least one of the drive motor and a permanent brake, starting a recognition function for detecting a downhill run-out at the latest after at least one of driving onto the downhill stretch and the transition to a thrust operation; and when a downhill run-out is detected, carrying out a shift to a higher gear while still in the thrust operation (thrust upshift) before at least one of driving onto the level ground and the transition to the traction operation.
