Vehicle information system
First Claim
1. A method for vehicle navigation comprising:
- maintaining a first storage for user-specific information for each of a plurality of users at a server computer system;
during a first communication session between the server computer a system and one of the users, accepting user-specific information from the user and storing said information in the first storage;
during a second communication session between the server computer system and a navigation system in a vehicle, providing navigation information from the server computer system to the navigation system at a location remote from the server computer system using the information previously stored in the first storage, and storing the navigation information in a second storage accessed locally by the navigation system; and
during an interactive session between the user and the navigation system after termination of the second communication session, using the navigation system to access and process the navigation information stored in the second storage, and to provide processed navigation information to the user.

Abstract
A vehicle information system which includes an in-vehicle system 105 and a centralized server system 120. The in-vehicle system communicates with the server system using a wireless communication link 110, such as over a cellular telephone system. A position system, such as a set of GPS satellites 140, provides positioning signals that are used by the in-vehicle systems, and optionally by the centralized server system to increase the accuracy of position estimates. In one version of the system, an operator specifies a destination to an in-vehicle system which validates the destination. The in-vehicle system transmits specification of the destination to a server system 125 at the centralized server. The server system computes a route to the destination and transmits the computed route to the in-vehicle system. The in-vehicle system guides the operator along the route. If the in-vehicle system detects that the vehicle has deviated from the planned route, it replans a new route to the destination using an in-vehicle map database.

31. Software stored on computer readable media comprising instructions for causing a computer system to:
-
maintain a first storage for user-specific information for each of a plurality of users at a server computer system;
during a first communication session between the server computer system and one of the users, accept information from the user and store said information in the first storage;
during a second communication session between the server computer system and a navigation system of a vehicle, provide navigation information from the sewer computer system to the navigation system at a location remote from the server computer system using the information that was accepted from said user, and storing the navigation information in a second storage accessed locally by the navigation system; and
during an interactive session between the user and the navigation system after termination of the second communication session, use the navigation system to access and process the navigation information stored in the second storage, and provide processed navigation information to the user.

32. A vehicle navigation system comprising:
-
means for maintaining a first storage for user-specific information for each of a plurality of users at a server computer system;
means for accepting information from one of the users and for storing said information in the first storage;
means for providing navigation on information from the server computer system to a navigation system of a vehicle at a location remote from the server computer system using the information that was accepted from said user, and storing the navigation information in a second storage accessed locally by the navigation system; and
means for, during an interactive session between the user and the navigation system, using the navigation system to access and process the navigation information stored in the second storage, and providing processed navigation information to the user.

39. A method for vehicle navigation comprising:
-
accepting user-preference information from a user and storing the user-preference information in a first storage at a server computer system;
providing part or all of the user-preference information from the server computer system to a vehicle navigation system at a location remote from the server computer system using the information stored in the first storage, and storing the user-preference information in a second storage accessed locally by the vehicle navigation system; and
during an interactive session between the user and the vehicle navigation system, using the vehicle navigation system to provide navigation information based on the user-preference information stored in the second storage. - View Dependent Claims (40, 41, 42, 43, 44, 45)
