Method of and device for determining a position of a vehicle
First Claim
1. A method of determining a position of a vehicle, comprising the steps of outputting position signals by a reception antenna and outputting traveling condition values by traveling condition sensors of a vehicle for determination of an absolute position of the vehicle and outputting an absolute position signal;
- from the absolute position signal and predetermined reference data of a reference system determining a relative position of the vehicle in the reference system, determining a position quality signal from a comparison of the absolute position signal and a reference position signal; and
using the position quality signal again for a new, subsequent determination of an absolute position of the vehicle.

Abstract
A position of a vehicle is determined by outputting position signals by a reception antenna and outputting traveling condition values by traveling condition sensors of a vehicle for determination of an absolute position of the vehicle and outputting an absolute position signal, from the absolute position signal and predetermined reference data of a reference system determining a relative position of the vehicle in the reference system, determining a position quality signal from a comparison of the absolute position signal and a reference position signal, and using the position quality signal for determination of an absolute position of the vehicle.
