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 in a text format;
sending the generated trip plan table to the vehicle over the network;
after sending the generated trip plan table, converting the locations in the text format to navigation prompts in an audio format;
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.

12. A vehicle navigation system comprising:
-
a computer-based vehicle unit located in a vehicle for receiving and transmitting trip request information and receiving trip plan navigation information, the computer-based vehicle unit having a processor and associated memory, a user interface, a global positioning system for determining vehicle coordinates, and a radio unit; a network configured to wirelessly send and receive trip request information to and from the vehicle unit via the radio unit; and a computer-based server in communication with the network for receiving trip request information from the computer-based vehicle unit, generating a trip plan according to navigation information stored in a memory associated with the server and the trip request information, and sending the generated trip plan to the vehicle unit over the network, wherein the generated trip plan includes a table of locations of the trip plan in a text format, and the vehicle unit further comprises a text-to-speech component configured to convert the locations in the text format to navigation prompts in an audio format. - View Dependent Claims (13)
