Method and device for calculating chassis height of a vehicle that has at
least three air-suspended wheel axles (2, 3, 4). The device includes a
control unit and two level sensors (9, 10). The control unit detects the
chassis height at the front axle (2) via a first level sensor (9) and at
the forward rear axle (3) via a second level sensor (10), and the control
unit calculates the chassis height at the rearmost wheel axle (4). An
object of the disclosure is to protect the rear axle installation with as
few level sensors as possible.
