Determining a relative movement of a chassis and a body of a wheeled vehicle
First Claim
1. An arrangement for determining a relative movement of a chassis and a vehicle body of a wheeled vehicle, said vehicle body being movably connected to the chassis, comprising a measuring entity which is arranged or can be arranged in the wheeled vehicle, wherein the measuring entity is configured to measure three respectively perpendicular linear accelerations of the wheeled vehicle and at least two rotational speeds, each relating to a rotational movement or a component of a rotational movement about a coordinate axis of the wheeled vehicle, wherein the at least two coordinate axes run perpendicularly to each other, and man analysis entity which is combined with the measuring entity and is operable to determine a momentary movement position of the relative movement using the three linear accelerations and the at least two rotational speeds, wherein the analysis entity comprises a calculating unit which is operable to calculate a plurality of momentary movement positions using the at least two rotational speeds and the three linear accelerations, and wherein each of the movement positions is a measure for a distance between the vehicle body and at least one wheel of the chassis.

Abstract
For determination of a relative movement of a chassis and a body of a wheeled vehicle, which is movably joined to the chassis, three linear accelerations of the wheeled vehicle, which extend perpendicular to each other, respectively, as well as at least two rotational speeds of one respective rotational movement or a component of a rotational movement about a coordinate axis of the wheeled vehicle are measured (in measuring device 1), the at least two coordinate axes running perpendicular to each other, respectively. A momentary position of the relative movement is determined (in evaluation unit 9) using the three linear accelerations and the at least two rotational rates.
