METHOD AND APPARATUS FOR ENSURING DATA PROTECTION DURING OFF-BOARD TOLL METERING

摘要

The invention relates to a method and an apparatus for determining toll roads, with a filter unit and an OBU which can communicate with one another, wherein the filter unit has map material, with the result that position data can be used to determine toll roads, comprising the following steps: - the OBU transmits position data of route sections to the filter unit, wherein the position data are transmitted in such a manner that the position data can be checked for relevance to tolls without knowledge of the identity of the OBU; - the position data transmitted are checked for relevance to tolls and toll levying data for charging and settlement are transmitted to the OBU; - the OBU stores the route sections which are subject to a toll in order to then form an overall route which is transmitted to a toll settlement point at the end of the journey.
