Abstract

A route guidance system for a navigation system includes a communication unit, a navigation unit, and a display unit. The communication unit transmits and receives vehicle coordinates from a remote lead vehicle. The navigation unit determines a route and provides directions for a user to the remote lead vehicle. The display unit displays a location of the user, the coordinates of the remote lead vehicle, the route from the user to the remote lead vehicle, and the directions.

First claim

What is claimed is:

1 . A route guidance system for a navigation system comprising:
a communication unit that transmits and receives vehicle coordinates from a remote lead vehicle; a navigation unit that determines a route and provides directions for a user to the remote lead vehicle; and a display unit that displays a location of the user, the coordinates of the remote lead vehicle, the route from the user to the remote lead vehicle, and the directions.

2 . The route guidance system of claim 1 , wherein the communication unit transmits or receives a friendship request to or from the remote lead vehicle.

3 . The route guidance system of claim 1 , wherein the communication unit transmits or receives a lead me request or a follow me request to or from the remote lead vehicle.

4 . The route guidance system of claim 1 , wherein the communication unit transmits and receives the vehicle coordinates over wireless communication to and from the remote lead vehicle.

5 . The route guidance system of claim 1 , wherein the communication unit transmits and receives the vehicle coordinates over vehicle to vehicle communication to and from the remote lead vehicle.

6 . The route guidance system of claim 1 , further comprising a dedicated short range communication system that transmits and receives the vehicle coordinates to and from a dedicated short range communication system on the remote lead vehicle.

7 . The route guidance system of claim 1 , further comprising a navigation screen displaying the location of the user, the coordinates of the remote lead vehicle, the route from the user to the remote lead vehicle, and the directions.

8 . The route guidance system of claim 7 , wherein the navigation screen is in a vehicle.

9 . The route guidance system of claim 7 , wherein the navigation screen is on a mobile navigation system, a mobile phone, or a smart phone.

10 . The route guidance system of claim 1 , wherein the navigation unit continuously routs the user to the remote lead vehicle.

11 . A method of route guidance for a navigation system comprising:
transmitting and receiving, by a communication unit, vehicle coordinates from a remote lead vehicle; determining, by a navigation unit, a route and providing directions for a user to the remote lead vehicle; and displaying, by a display unit, a location of the user, the coordinates of the remote lead vehicle, the route from the user to the remote lead vehicle, and the directions.

12 . The method of claim 11 , further comprising transmitting or receiving, by the communication unit, a friendship request to or from the remote lead vehicle.

13 . The method of claim 11 , further comprising transmitting or receiving, by the communication unit, a lead me request or a follow me request to or from the remote lead vehicle.

14 . The method of claim 11 , further comprising transmitting and receiving, by the communication unit, the vehicle coordinates over wireless communication to and from the remote lead vehicle.

15 . The method of claim 11 , further comprising transmitting and receiving the vehicle coordinates over vehicle to vehicle communication to and from the remote lead vehicle.

16 . The method of claim 11 , further comprising continuously routing, by the navigation unit, the user to the remote lead vehicle.

17 . The method of claim 11 , further comprising notifying the user, by the navigation unit, of upcoming turns already made by the remote lead vehicle.

18 . The method of claim 11 , further comprising sharing, by the communication unit, music between the user and the remote lead vehicle.

19 . The method of claim 11 , further comprising displaying, by the display unit, a notification when the user passes the remote lead vehicle.

20 . The method of claim 11 , further comprising distinguishing, by the display unit, between the user and the remote lead vehicle on the display.
