Claim:
1. A method of driver-assisted rocking a motor vehicle free from a depression ( 6 ), the vehicle comprising a drive-train ( 1 ) having an automatically controllable drive torque adjusting element ( 3 ) by which drive torque can be transmitted to at least one drivable vehicle wheel ( 5 ), when a driver of the motor vehicle deflects an accelerator pedal ( 8 ) to an accelerator pedal position different from an unactuated position, the drive torque adjusting element ( 3 ) being controlled as a function of the accelerator pedal position in relation to the drive torque that can be transmitted by the drive torque adjusting element ( 3 ), and, in a rocking-free situation in which at least one vehicle wheel ( 5 ) has to be moved clear of the depression ( 6 ), by the driver alternating between deflection of the accelerator pedal ( 8 ) and release of the deflection of the accelerator pedal ( 8 ), the driver thereby producing a cyclically fluctuating drive torque at the at least one drivable vehicle wheel ( 5 ), the method comprising: continually monitoring the accelerator pedal position; upon recognizing a beginning, or an imminently beginning reduction of the deflection of the accelerator pedal, or a parameter derived therefrom, concluding that a full release of the deflection of the accelerator pedal is imminent; and upon concluding that the full release of the deflection of the accelerator pedal is imminent, activating the drive torque adjusting element (
