1. Method to determine a slip state of the compactor roller of a soil compactor caused by an oscillation motion of a compactor roller, comprising the steps: a) preparing an acceleration quantity related to the oscillation motion of the compactor roller based on an acceleration of the compactor roller essentially in a direction parallel to a surface of a soil being compacted;b) based on the acceleration quantity, preparing an acceleration frequency spectrum; andc) based on the acceleration frequency spectrum, determining the slip state of the compactor roller by determining a slip indicator representing the slip state of the compactor roller, wherein said slip indicator is determined based on a ratio of the amplitude of the acceleration-frequency spectrum at a first frequency to the amplitude of the acceleration-frequency spectrum at a second frequency. 2. Method according to claim 1, wherein the acceleration quantity is determined on the basis of an output signal from at least one acceleration sensor detecting essentially the acceleration of one compactor roller axis of rotation. 3. Method according to claim 1 wherein at step b) the acceleration-frequency spectrum determined by Fourier transform of the acceleration quantity. 4. Method according to claim 3, wherein the Fourier transform is a fast Fourier transform. 5. Method according to claim 1 wherein at step c) the slip state is determined based on a change in amplitude at the oscillation frequency of the compactor roller. 6. Method according to claim 1, wherein a frequency of the first frequency and second frequency corresponds essentially to illation frequency of the compactor roller. 7. Method according to claim 1, wherein a frequency of first frequency and second frequency corresponds essentially to an uneven-numbered multiple or to an even-numbered multiple of the oscillation frequency of the compactor roller.
