Method, system and apparatus for provision of a "Private Mode" for Combined Tolling and Telematic On-Board Units

Disclosed is a method and system for user privacy friendly operation of traffic telematic systems, combined with electronic toll collection functionality.

Introduction

Electronic Toll Collection Systems

Electronic Toll Collection Systems are used to determine the road usage of a vehicle (mostly a car or a truck) and calculate an appropriate fee/ tax by electronic means. The amount is charged by the system either in pre or post payment mode. Different technologies for the determination of the road usage e.g. infrastructure based (e.g. by DSRC technology (Dedicated Short Range Communication) with microwave or infrared technology) or GNSS (Global Navigation Satellite System; e.g. GPS positioning (Global Positioning System)) are already used. Hybrid combinations of localization methods are also well known. Additionally localization via cell information of a cellular network is a practiced technical embodiment.

Data privacy friendly electronic tolling system solutions are already known to protect the tolling user data (position and time) against unauthorized access.

Telematic Systems

Telematic Systems are widely used in fleet management solutions, e.g. for monitoring of the operational parameters of a truck equipped with a telematic unit. The telematic unit therefore is often connected to the electronic bus system (e.g. CAN-bus) of the vehicle. In addition such a unit offers a communication channel between the on-board unit and the telematic service central system for information exchange (e.g. text or voice messages for the truck or taxi driver).

Data privacy for telematic systems nowadays can be nearly neglected because of its mainly commercial transportation business usage, where the vehicle driver (e.g. truck or taxi) is requested and lawful allowed being traceable. Telematic systems are commonly not used for private persons, where user data privacy is very important.

Both systems (Tolling and Telematic) comprise a cellular network data modem in order to send messages (toll transaction for payment of used roads or telematic messages for e.g. communication issues), which allows tracking as well.

Problem to be solved

When combining tolling and telematic system features, the total system has to bridge one constrain: if the end-user requires being not traceable in vehicle location and time, the system is not allowed to store position information of the on-board unit at any time. The position information can be determined by e.g. a GPS-receiver within the on-board unit, but as well simply by loc...
