Method and system for controlling a chassis of a vehicle

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), wherein, in order to determine the crest-dip indication, a progression of the vertical wheel acceleration is compared to a progression of the vertical body acceleration, and
• controlling the chassis on the basis of the crest-dip indication.

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), and
• controlling the chassis on the basis of the crest-dip indication,
• wherein the vertical wheel acceleration of all four wheels of the vehicle is detected, and each vertical wheel acceleration is compared to a body acceleration in order to determine the crest-dip indication,
• wherein vertical wheel accelerations of the wheels of a front axle are compared with a first threshold in order to determine the crest-dip indication, and wheel accelerations of wheels of a rear axle are compared with a second threshold value that is not equal to the first threshold value.

A system for controlling a chassis of a vehicle, said system comprising:

• (i) a wheel acceleration sensor for detecting a vertical wheel acceleration of a wheel of the vehicle,
• (ii) a body acceleration sensor for detecting a vertical body acceleration of a body of the vehicle, and
• (iii) a control unit configured to:
• detect a vertical wheel acceleration of the wheel of the vehicle,
• detect a vertical body acceleration of the body of the vehicle,
• determine 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),
• determine 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
• control the chassis on the basis of the crest-dip indication and the crest-dip information.
