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.

Claims

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.

2. The vehicle-to-vehicle (V2V) communication system of claim 1 wherein:

bandwidth used by the wireless transmit gateway is distinct from the bandwidth used by the V2V transmitter.

3. The vehicle-to-vehicle (V2V) communication system of claim 1 wherein:

data transmitted by the wireless gateway comprises a subset of the data transmitted by the V2V transmitter.

4. The vehicle-to-vehicle (V2V) communication system of claim 1 further comprising:

a wireless receive gateway configured to receive gateway input information from at least one the wireless protocols in the Markush group;

(WiFi, Bluetooth, cellular data).

5. The vehicle-to-vehicle (V2V) communication system of claim 4 further comprising:

a validity testing module, wherein the validity testing module tests the receive gateway input information for V2V validity;

wherein the V2V transceiver transmits receive gateway input information only if the V2V validity test is passed.

6. The vehicle-to-vehicle (V2V) communication system of claim 1 further comprising:

a wireless, mobile, consumer electronic device, “

the consumer device,”

configured to receive data from the wireless transmit gateway;

wherein the consumer device comprises data comprising its own location;

an application in non-transitory memory in the consumer device configured to compute a possible collision involving the consumer device, and the computation uses both its own location and received V2V message data transmitted via the wireless transmit gateway;

wherein the application is configured to generate a warning based on the computation of a possible collision.

7. The vehicle-to-vehicle (V2V) communication system of claim 6 wherein:

wherein the application executes in the background such that no active involvement of the user of the consumer device is required;

wherein the computation is performed multiple times using data at least partially distinct from data used in an immediately prior computation.

8. The vehicle-to-vehicle (V2V) communication system of claim 6 wherein:

wherein the application computes a likely future location of the user of the consumer device;

wherein the application is configured to compute a risk value of a possible collision involving the consumer device and the computation is responsive to the likely future location;

wherein the application is configured to generate a warning if the computed risk value exceeds a risk threshold.

9. The vehicle-to-vehicle (V2V) communication system of claim 8 wherein:

wherein the warning is at least partially a V2V wireless transmission message transmitted to a gateway operatively connected to the V2V transceiver located the transmitting vehicle.

10. The vehicle-to-vehicle (V2V) communication system of claim 1 further comprising:

a cellular communication device within wireless range of the wireless transmit gateway;

wherein the wireless transmit gateway is configured to send a notification message via a predetermined emergency cellular number, using the cellular communication device;

a risk computation module;

wherein this module computes a risk value;

wherein the notification message is sent when the risk value is equal to or greater than a cellular notification risk threshold.
