First Claim
Patent Images
1. An in-vehicle collision and warning system (IVCAWS) for a vehicle comprising:
- a vehicle air bag collision protection system including sensors and a processor, said processor being capable of discriminating a collision, near-collision or dangerous condition;
means for transmitting a warning or information signal upon detection of said collision, near-collision or dangerous condition; and
means responsive to a received warning or information signal forproviding a warning to an operator of the vehicle,selectively relaying the warning or information signal directionally, andselectively controlling the vehicle for collision avoidance.

Abstract
Peer-to-peer communications between vehicles providing warning of a collision or near-collision event and/or collision avoidance is controlled by otherwise underutilized air bag deployment processors in respective vehicles. Direction of reception of warning signals is used to selectively control relaying of warning signals at differentiated warning levels, collision avoidance actions and/or in-vehicle warning alarms to operators of vehicles in the vicinity of an event.

11. A method of in-vehicle collision avoidance and warning comprising steps of:
-
predicting an event in an originating vehicle using an air bag deployment processor; transmitting a warning signal to another vehicle; directionally receiving said warning signal at said another vehicle; and
selectively anddirectionally relaying said warning signal at a different warning level to other vehicles responsive to a direction of reception of said directionally receiving step. - View Dependent Claims (12, 13, 14, 15)
