Determining a relative movement of a chassis and a body of a wheeled vehicle
First Claim
1. An arrangement for determining a vertical movement of a vehicle chassis relative to a vehicle body of a wheeled vehicle, said vehicle body being movably connected to the chassis, comprisinga measuring entity 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, andan analysis entity which is combined with the measuring entity and is operable to determine a momentary vertical distance between the vehicle body relative to the vehicle chassis using the three linear accelerations and the at least two rotational speeds, and without using any height-level or suspension travel measurements as input for determining the momentary vertical distance,wherein the analysis entity comprises a calculating unit which is operable to calculate a plurality of the momentary vertical distances using the at least two rotational speeds and the three linear accelerations.

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.
