Method and arrangement for monitoring a measuring device located in a wheeled vehicle
First Claim
1. An arrangement for monitoring a measuring device disposed in a wheeled vehicle, comprising the measuring device, said measuring device being operable to measure three linear accelerations of the wheeled vehicle which are oriented perpendicular to one another and three rotation rates of a rotational movement or of a component of a rotational movement about an axis of the wheeled vehicle, the three axes running perpendicular to one another, an orientation determining device for determining an orientation of the wheeled vehicle from the three rotation rates in a coordinate system external to the vehicle, and a monitoring device for monitoring at least one of the measured linear accelerations using an output variable of the orientation determining device and using a comparison variable.

Abstract
For monitoring of a measuring device (1), located in a wheeled vehicle, the measuring device (1) is configured so as to measure three linear accelerations (in unit 3) of the wheeled vehicle, which extend perpendicular to each other, respectively, as well as three rotational speeds (in unit 4) and one respective rotational movement or a component of a rotational movement about an axis of the wheeled vehicle, the three axes running perpendicular to each other, respectively. At least components of an orientation of the wheeled vehicle in a vehicle-external coordinate system are determined (in unit 7) from the three rotational speeds, and at least one of the measured linear accelerations is monitored (in unit 9) using at least the components of the orientation and a comparative variable (from unit 8).
