System and method for reducing the amount of repetitive data sent by a server to a client for vehicle navigation
First Claim
1. A vehicle navigation method comprising:
- initiating a trip request, including trip request information;
determining vehicle coordinates;
sending vehicle coordinates and the entered trip request information to a server over a network;
generating a trip plan according to navigation information stored in a memory associated with the server, the vehicle coordinates, and the trip request information, wherein the generated trip plan includes a table of locations of the trip plan with associated navigation prompts;
sending the generated trip plan table to the vehicle over the network;
comparing present vehicle coordinates to the trip plan table; and
if, according to the comparison, the vehicle coordinates are within a threshold value from a location in the table, presenting the navigation prompt associated with the location in the table that is within the threshold value of the vehicle'"'"'s location.

Abstract
A system and method for reducing the amount of repetitive data sent by a server to a client for vehicle navigation. The system includes a computer-based vehicle unit located in a vehicle, a gateway configured to wirelessly send and receive trip information to and from the vehicle unit, and a computer-based server in communication with the gateway over a network. The vehicle unit wirelessly receives signals from a computer-based server that includes the desired navigation information in packet form. The vehicle unit includes a user interface component that presents the received navigation information and records user requests. The server processes the requests, generates a trip plan according to the navigation information and sends the generated trip plan back to the vehicle unit via a gateway when a request has been completed.
