Abstract

A system and method are provided to determine the side-impact collision status of a nearby vehicle or vehicles. If a nearby vehicle has been in a collision, responsive systems may be triggered automatically. Responses may include warning the driver of the host vehicle and/or warning drivers of other vehicles or centralized networks by, among other methods, V2V or V2I communications. Responses may also include automatically triggering countermeasures in the host vehicle.

Claims

1. A system for determining a side-impact collision status of a vehicle and responding to same, the system comprising;

(a) a mechanism for detecting a presence of the vehicle;

(b) a controller for determining the lateral displacement of the vehicle in predetermined time intervals and comparing same to threshold values to determine the side-impact collision status of the vehicle; and

(c) if the vehicle has been in a side-impact collision, a signal is configured to trigger a response.

2. The system of claim 1 wherein the mechanism is a sensing system that comprises at least one of a radar sensor, a lidar sensor or a vision-based sensor.

3. The system of claim 1 wherein the mechanism comprises vehicle-to-vehicle communications.

4. The system of claim 1 wherein the response is a visual warning in the host vehicle.

5. The system of claim 1 wherein the response is an audible warning in the host vehicle.

6. The system of claim 1 wherein the response is as haptic warning in the host vehicle.

7. The system of claim 1 wherein the response is to alert drivers of other vehicles of the collision status of the nearby vehicle via vehicle-to-vehicle communications.

8. The system of claim 1 wherein the response is to alert drivers of other vehicles of the collision status of the nearby vehicle via setting the hazard lights of the host vehicle to on.

9. The system of claim 1 wherein the response is to at least one countermeasure.

10. The system of claim 1 further comprising:

(d) if the vehicle has been in a side-impact collision, an apparatus for identifying non-drivable paths, drivable paths, and preferred drivable paths.

11. The system of claim 10 further comprising a controller for selecting preferred drivable paths among available drivable paths.

12. The system of claim 10 further comprising:

(e) a signal configured to trigger an audio or visual alert in the host vehicle that identifies one or more of non-drivable, drivable and preferred drivable path information.

13. The system of claim 12 wherein the driving route information is communicated via vehicle-to-vehicle or vehicle-to-infrastructure communication.

14. A method of avoiding a collision, comprising:

(a) determining a side-impact collision status of a vehicle based upon lateral displacement of the vehicle in predetermined time intervals relative to the vehicle'"'"'s longitudinal direction of travel and comparing measured lateral displacement to predetermined thresholds to determine if the side-impact collision status is positive; and

(b) automatically responding to the side-impact collision status.

15. The method of claim 14 wherein the automatically responding step comprises providing a visual warning to a driver of the host vehicle.

16. The method of claim 14 wherein the automatically responding step comprises providing an audible warning to a driver of the host vehicle.

17. The method of claim 14 wherein the automatically responding step comprises providing a haptic warning to a driver of the host vehicle.

18. The method of claim 14 wherein the automatically responding step comprises providing a warning to drivers of other vehicles via vehicle-to-vehicle communications.

19. The method of claim 14 wherein the automatically responding step comprises providing a warning to drivers of other vehicles via turning on hazard lights on the host vehicle.

20. The method of claim 14 wherein the automatically responding step comprises applying at least one countermeasure.
