Motor vehicle navigation system for computing route between starting point and destination, has global positioning system determining current position, and processor outputting warning information, if current position lies on road

摘要

The system has a storage device (SPE) for storing information about geographical process of road and for storing attributes, where the road is assigned with the information and a predetermined attribute, Another road is assigned with the information about geographical process of the latter road and is not assigned with the predetermined attribute. A display device (AE) displays the information corresponding to the roads, and a global positioning system (GPS) determines current position. A processor (PE) outputs warning information, if the current position lies on the latter road.
