Abstract
The vehicle routing and guidance system includes a vehicle-based navigation system (35) located in a vehicle, which includes an input device (38) for entry of one or more destinations (B) to which the vehicle is to travel and a self-locating device for determining location of the vehicle, a central server 12 located outside of the vehicle for making navigational information available to the navigation system, for determining a route (16) to the destination or destinations (B) provided to the navigation system and for dividing the route (16) piecewise into route sections (34), and transmitter and receiver devices for at least temporarily establishing communication between the central server (12) and the navigation system (35) to transmit the route sections (34) separately to the navigation system (35) so that the route (16) is transmitted in a piecewise manner to the navigation system (35).
