System and Method for Vehicular Communications
First Claim
1. A communications method for transmitting a message from a vehicle having one or more externally detectable signalers, said method comprising the steps of:
- producing a dynamic signal signifying traveling information associated with dynamic operation of said vehicle; and
sending to the one or more signalers in response to said dynamic signal a main signal modulated and encoded to indicate at least some of the traveling information, modulation being conducted at or above a critical flashing frequency or with a pulse duration that is human imperceptible or with an inter-pulse blank that is human imperceptible.

Abstract
A method for communicating with a vehicle has a generator for producing a data stream that can indicate, street sign information, house number, lead vehicle information, traffic information, oncoming vehicle information, juxtaposed vehicle information, a voice channel, etc. vehicle information can indicate braking, low beam requests, direct or indirect traffic flow information, adjacency, partial adjacency, or presence of nearby vehicles, etc. This signal is generated by at least one of: the sign, house number, oncoming vehicle, lead vehicle, operator of the lead vehicle, operator of the oncoming vehicle, operator of the juxtaposed vehicle, a traffic control system. A device for generating such data streams is discussed, as well as, a device for receiving such data streams. Information pertinent to the people in the vehicles or operation of the vehicle can be modulated on the link.
