Abstract
A method for determining toll routes, using a filter unit and a vehicle onboard unit onboard unit in communication with one another, the filter unit having map material so that toll routes are determinable on the basis of a position data, includes transmitting, by the onboard unit, the position data to the filter unit so that the position data is checkable for toll relevance without revealing an identity of the onboard unit. The transmitted position data is checked for toll relevance. Toll collection data is transmitted to the onboard unit for charge calculation and billing. The toll routes are stored by the onboard unit. The toll routes are transmitted to a toll collection point for the charge calculation.

16. A method for determining toll routes, using a filter unit and a vehicle onboard unit onboard unit in communication with one another, the filter unit having map material so that toll routes are determinable on the basis of a position data, the method comprising the following steps:
-
transmitting, by the onboard unit, the position data to the filter unit so that the position data is checkable for toll relevance without revealing an identity of the onboard unit; checking the transmitted position data for toll relevance; transmitting toll collection data to the onboard unit for charge calculation and billing; storing the toll routes by the onboard unit; and transmitting the toll routes to a toll collection point for the charge calculation. - View Dependent Claims (17, 18, 19, 20, 21)

22. A server system for determining toll routes, comprising:
-
a filter unit including a memory having map material stored therein and a processing unit configured to check position data for toll relevance by accessing the memory, free of an identity of the onboard unit, the filter unit being configured to transmit toll collection data to the onboard unit for charge calculation and billing if a toll relevance exists, the filter unit being configured to determine toll routes on a basis of the position data; and a vehicle onboard unit onboard unit in communication with the filter unit across a network, and configured to send the position data to the filter unit. - View Dependent Claims (23, 24)

25. In combination, a vehicle onboard unit and a filter unit configured to determine toll routes from position data transmitted to the filter unit by the onboard unit, comprising:
-
a memory in the filter unit containing map material so that toll routes can be determined on the basis of the position data; a transmission unit in the onboard unit configured to send position data of at least one subroute to the filter unit, wherein the position data is checkable for toll relevance free of an identity of the onboard unit; a receiving unit in the onboard unit configured to receive toll collection data from the filter unit for charge calculation and billing operations; a memory in the onboard unit configured to store the at least one subroute so as to form the entire route; and a transmission unit in the onboard unit configured to transmit the entire route to a toll collection point at an end of a trip. - View Dependent Claims (26, 27, 28, 29, 30)
