Risk management in a vehicle anti-collision system
First Claim
1. A vehicle-to-vehicle (V2V) communication system comprising:
- a set of V2V wireless transmitters located within communication range of each other wherein the V2V transmitters in the set transmit V2V messages, wherein each message comprise one or more message types;
a plurality of V2V message types;
wherein at least one V2V message type comprises a situation risk value;
wherein one of the set of V2V transmitters transmits a risk message;
wherein the situation risk value in the risk message is an integer.

Abstract
Device, system and method, in a vehicle communication system, of transmitting a risk value in a message, wherein the risk value identifies quantitatively a risk of vehicle collision. Embodiments determine risk value by combining sub-risk values wherein sub-risks comprise: (i) vehicle behavior; (ii) weather and road conditions; (iii) current traffic; and (iv) location history. Embodiments include driver warnings responsive to the risk value in a received message. Embodiments include a collision type in a message. Embodiments include unique features of: risk is applicable to receiving vehicles; risk is applicable to a geographical region; computation and storage of location histories; messages free of IP and MAC addresses; haptic devices used for driver warning.

14. A method of vehicle-to-vehicle (V2V) collision avoidance comprising:
-
determining a risk of collision by a first vehicle; generating a situation risk value responsive to the risk of collision; transmitting by the first vehicle a V2V risk message comprising the situation risk value; receiving the V2V risk message by a second vehicle; generating a warning to the driver of second vehicle, wherein the warning is responsive the situation risk value in the risk message.

15. A method of vehicle-to-vehicle (V2V) collision avoidance comprising:
-
generating a collision type value responsive to the type of a predicted collision; transmitting by the first vehicle a V2V collision type message comprising the collision type value; receiving the V2V collision type message by a second vehicle; generating a warning to the driver of second vehicle, wherein the warning is responsive the collision type value in the V2V collision type message.

16. A method of vehicle-to-vehicle (V2V) collision avoidance comprising:
-
accepting a collision type; generating a collision type value responsive to the collision type; transmitting by a first vehicle a V2V collision type message comprising the collision type value; receiving the V2V collision type message by a second vehicle; generating a warning to a driver of second vehicle, wherein the warning is responsive the collision type value in the V2V collision type message.
