A method of rocking a vehicle free, the vehicle having a drive-train with a torque adjusting element which transmits drive torque to a vehicle wheel. The adjusting element is controlled as a function of an accelerator pedal position. In a rocking-free situation in which the vehicle wheel is to be moved from a depression by alternating deflection and release of the accelerator pedal, the driver produces a cylindrically fluctuating drive torque at vehicle wheel. The accelerator pedal position is continuously monitored and upon recognizing a beginning or imminently beginning reduction of the accelerator pedal deflection or a parameter derived therefrom, an imminent full release of the deflection of the accelerator pedal is concluded and the adjusting element is actuated in anticipation so that the vehicle wheel is immediately freed from a drive torque that has been active until then.
