EXTRA-VEHICULAR ANTI-COLLISION SYSTEM
First Claim
1. A vehicle-to-vehicle (V2V) communication system comprising:
- a V2V transceiver configured to operate in a transmitting vehicle;
wherein the V2V transmitter is configured to accept as input subject vehicle position and subject vehicle heading;
wherein the V2V transmitter broadcasts V2V messages, at regular intervals, using a V2V protocol, wherein the V2V messages comprise;
(i) the subject vehicle position;
(ii) the subject vehicle heading; and
(iii) subject vehicle speed;
a wireless transmit gateway configured to transmit V2V information over at least one the wireless protocols in the Markush group;
(WiFi, Bluetooth, cellular phone, cellular data) and wherein the wireless protocol used by the wireless transmit gateway is not the V2V protocol.

Abstract
Device, system and method, in a vehicle communication system using a first protocol, of implementing a gateway using a distinct second protocol. Embodiments include a first protocol transmitting in a government set vehicle safety band, and a second protocol in the set of: WiFi, Bluetooth, cellular phone and cellular data. An embodiment uses a validity-testing module to prevent insecure messages on the second protocol from interfering with the first protocol. Both one-way and two-way inter-protocol message transfers are described. Embodiments use the gateway to communicate from a vehicle using the first protocol to pedestrians, bicyclists, and equipped animals using the second protocol. Embodiments use a computed and transmitted risk-of-collision value. Embodiments include a driver or operator warning responsive to the transmitted risk value. Embodiments include computation of likely future position.

11. A method of preventing collisions involving a vehicle comprising:
-
determining the location, speed and heading of the vehicle; receiving the location of a mobile consumer electronic device to the vehicle; comparing the received location of the mobile consumer electronic device to the future location of the vehicle; generating a warning to the driver of the vehicle if the difference between the two locations is less than a warning threshold.
