ABSTRACT:
Within the framework of the procedure for optimizing the rocking free of vehicles with an automatic transmission, a multiple clutch gear or an automatic shift gear, in order to recognize a situation which requires a rocking free of the vehicle, the speeds of the driving wheels are compared to the speeds of the non-driven wheels. When the driving wheels are spinning or have a specific speed, without a corresponding increase in speed or speed of the non-driven wheels, the necessity for rocking free of a vehicle is recognized.
