Method and device for transmitting navigation information from a data center to a vehicle-based navigation system

摘要

The invention relates to a method and a device for transmitting navigational information from a central data unit (2000) to a navigation system (3000) which is located in a motor vehicle. The device comprises a request profile generator (3810) for generating an individual request profile according to the navigational information required by the navigation system (3000) which is located in the motor vehicle; a communication device (1000) for transmitting the individual request profile from the navigation system (3000) to the central data unit (2000) using a common air interface; a preparation device provided in the central data unit for analysing the transmitted individual request profile, for making available the navigational information which is required in the navigation system (3000), located in the motor vehicle and for retransmitting the required navigational information from the central data unit (2000) to the navigation system (3000) located in the motor-vehicle via the common air interface; and comprises a navigational information integration system for integrating the retransmitted required navigational information into the navigation system (3000) located in the motor-vehicle.
