CHASSIS HEIGHT MEASUREMENT SYSTEM FOR A VEHICLE

A chassis height measurement system (100) for a vehicle (1000), in particular commercial vehicle (1001) or passenger vehicle (1006), with an axle (822) suspended by a suspension system (840), in particular an air suspension system (842), comprising:- a height sensor (110), adapted to provide a road distance signal (D1), which represents a distance between a road surface (2000) and a chassis (800) of the vehicle (1000), wherein- the height sensor (110) is a radar sensor (120) which is fixed to the chassis (800), and with a field of view (VF) defined by a measurement aperture (122), wherein- the radar sensor (120) is arranged such that an axle reference object (820), in particular the axle (822), is within the field of view (VF), wherein- the radar sensor (120) is adapted to provide an axle distance signal (D2), which represents a distance between the chassis (800) and the axle reference object (820).
