First Claim
Patent Images
1. A program storage device readable by a controller installed in a first vehicle, tangibly embodying a program of instructions executed by said controller to perform method steps for automatically exchanging information with other vehicles in the event of a collision, said method comprising:
- sensing said collision by said first vehicle;
transmitting a signal to said controller indicating said collision;
upon reception of said signal by said controller, forming a message comprising an identification of said first vehicle;
transmitting said message to at least a second of said vehicles within a threshold distance of said first vehicle; and
storing said first message in a memory of at least said second of said vehicles and receiving at least one witness message from at least one other of said vehicles indicating that the driver of said at least one other of said vehicles is a witness to said collision.

Abstract
A method for exchanging information between vehicles involved in or near a collision site. When a collision is sensed by one vehicle, a message is transmitted from the one vehicle to at least one of the other vehicles within a threshold distance of the one vehicle. The message contains at least the identity of the one vehicle and preferably driver information, insurance information, along with the time and place of the collision.
