Device for temporarily overcoming the loss of a satellite navigation signal, for satellite navigation-based dual toll systems
First Claim
1. A method for an electronic toll, wherein position coordinates of a vehicle normally determinable via a satellite-based position determination system, comprising:
- calculating at least one signature, characteristic of a road on which a vehicle is traveling upon, based upon the position coordinates of the vehicle; and
using the calculated at least one signature to determine whether the road being traveled upon is subject to a toll, wherein the position coordinates are determinable using an inertial navigation system, at least in an event of a partial failure of the satellite-based position determination system.

Abstract
The invention relates to a method for electronically charging tolls, whereby actual position coordinates (OKO) of a vehicle are determined by means of at least one position fixing system, in order to determine if a toll road segment has been taken. Said position coordinates (OKO) are determined at least temporarily by means of a satellite-aided position fixing system (SGS). At least one signature (SIG), which is characteristic of the road segment taken by said vehicle, is calculated by means of said position coordinates of the vehicle (FA1, FA2). Said signature (SIG) permits the determination of whether the road segment taken is a toll road segment or not. At least in case of partial failure of said satellite-aided position fixing system (SGS), the position coordinates are determined by means of an inertial navigation system (TNS).
