A vehicle information system which includes an in-vehicle systemand a centralized server system. The in-vehicle system communicates with the server system using a wireless communication link, such as over a cellular telephone system. A position system, such as a set of GPS satellites, 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 systemat 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 as deviated from the planned route, it re-plans a new route to the destination using an in-vehicle map database.

Vehicle information system

A vehicle information system which includes an in-vehicle system and a centralized server system. The in-vehicle system communicates with the server system using a wireless communication link. The vehicle receives a reference signal from a positioning system, computes position data related to the location of the vehicle using the received reference signal, and transmits the position data to the server. The vehicle receives from the server position correction data and determines estimated coordinates of the vehicle, including combining data computed from the received reference signal and the position correction data. Computing the position data and determining the estimated coordinates are performed repeatedly for an interval of time using the same received position correction data, and subsequent to the interval of time, are performed repeatedly without using the received correction data.
