1. A method for controlling a chassis of a vehicle, said method comprising:
detecting a vertical wheel acceleration of a wheel of the vehicle,
detecting a vertical body acceleration of a body of the vehicle,
determining a crest-dip indication by comparing the vertical wheel acceleration and the vertical body acceleration, wherein the crest-dip indication specifies whether or not the vehicle is currently driving over a crest (K) or a dip(S),
determining crest-dip information on the basis of the vertical wheel acceleration and the vertical body acceleration, which crest-dip information comprises an indication of an extent of the crest (K) or dip(S) currently being driven over, and
controlling the chassis on the basis of the crest-dip indication and the crest-dip information.
