Inter vehicular ad hoc routing protocol and communication system
First Claim
1. A vehicular communication system adapted for use with a traveling host vehicle and a traveling remote vehicle spaced from and communicatively coupled to the host vehicle, said system comprising:
- at least one locator sub-system configured to determine current position coordinates for the host vehicle at multiple points along a trip, said host vehicle including a controller communicatively coupled to the sub-system, and configured to store for at least a period the position coordinates, so as to build a history of host vehicle trail coordinates, and autonomously determine a host vehicle heading, based on the current position coordinates, and history of trail coordinates, said host and remote vehicles being cooperatively configured to selectively transmit a message from the host vehicle to the remote vehicle based on the current position or trail coordinates of the host vehicle.

Abstract
A routing protocol and inter-vehicle communication system adapted for use with a traveling host vehicle, and at least one traveling remote vehicle, includes a locator sub-system configured to determine a plurality of current position coordinates for the host and remote vehicles. The preferred system is configured to store trail coordinates, derive vehicular headings and trail polygons from the trail coordinates, and effect the directional multi-hop propagation of a message by comparing current position coordinates, trail coordinates, headings and/or trail polygons of the host and remote vehicles.

12. A vehicular communication system adapted for use with a traveling host vehicle and at least one traveling remote vehicle spaced from and communicatively coupled to the host vehicle, said system comprising:
-
at least one locator sub-system configured to determine current position coordinates for the host vehicle at multiple points along a trip, said host vehicle including a controller communicatively coupled to the sub-system, and configured to store for at least a period the position coordinates, so as to build a history of host vehicle trail coordinates, and autonomously determine a host vehicle heading and construct a trail polygon, based on the current position coordinates, and history of trail coordinates, said locator sub-system and remote vehicle being cooperatively configured to concurrently determine and store current position coordinates for said at least one remote vehicle, at multiple points along a remote vehicle trip, so as to build a history of remote vehicle trail coordinates, and to construct a remote vehicle trail polygon from the trail coordinates. said host and remote vehicles being cooperatively configured to selectively transmit a message from the host vehicle to the remote vehicle based on the current position and trail polygons of either the host or remote vehicle, said at least one remote vehicle being further configured to re-transmit the message to another remote traveling vehicle upon receipt of the message.

13. A method of selectively and autonomously communicating a message from a source to at least one traveling vehicle, said method comprising the steps of:
-
a. determining current position coordinates for the source;
b. determining and storing current position coordinates relative to the source, at multiple points along a trip, so as to build a history of trail coordinates, for said at least one traveling vehicle;
c. determining a current heading, based on the history of trail coordinates, relative to the source, for said at least one traveling vehicle; and
d. causing the message to be selectively transmitted from the source to said at least one traveling vehicle, based on the current heading and position coordinates of the traveling vehicle relative to the source. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
