Rear end advanced collision technology

1. A method of controlling stability of a vehicle comprising:

monitoring vehicle information with an electronic control unit;

determining a rear collision from a second vehicle approaching from a rear direction is likely;

sending a first response signal to at least one vehicle system from the electronic control unit prior to the rear collision, wherein the at least one vehicle system changes state based upon the first response signal to prepare the vehicle for the rear collision;

determining a probability of collision following the at least one vehicle system changing state;

determining a clearance distance which the vehicle may be moved forward without and not contact a preceding object; and

sending a signal to the brake system to release the brakes such that the vehicle may roll forward the determined clearance distance and applying the brakes to stop the vehicle at the clearance distance when the probability of collisions is that the rear collision is still likely.

2. The method of claim 1 , further comprising sending at least a first safety signal, wherein sending the first safety signal includes sending at least one of a warning signal to prepare an occupant of the vehicle, a warning signal to prepare an occupant of the second vehicle, and a signal to activate safety device to protect an occupant of the vehicle.

3. The method of claim 2 , wherein the sending the first safety signal to the at least one vehicle system includes sending a warning signal including one of an auditory signal, a visual signal, and a haptic signal.

4. The method of claim 2 , wherein the sending the signal to activate a safety device includes pre-charging a head support system.

5. The method of claim 1 , wherein the sending the first response signal to the at least one vehicle system includes sending a signal to initiate at least one of; pre-charging the brakes, deploying a rear facing bumper to an extended collision position, and lowering a bumper or vehicle height.

6. The method of claim 1 , further comprising determining a collision from with an object in a forward direction is likely to result from a rear collision.

7. The method of claim 1 , further comprising sending a third signal to at least one vehicle system to prepare for a forward vehicle collision.

8. A method of controlling stability of a vehicle comprising:

monitoring vehicle information with an electronic control unit;

determining a rear collision from a second vehicle approaching from a rear direction is likely; and

sending at least a first safety signal and a first response signal to at least one vehicle system from the electronic control unit prior to the rear collisions determining a probability of collision following the at least one vehicle system changing state;

determining a clearance distance which the vehicle may be moved forward without and not contact a preceding object; and

sending a signal to the brake system to release the brakes such that the vehicle may roll forward the determined clearance distance and applying the brakes to stop the vehicle at the clearance distance when the probability of collisions is that the rear collision is still likely.

9. The method of claim 8 , wherein the at least one vehicle system changes state based upon the first response signal to prepare the vehicle for the rear collision.

10. The method of claim 8 , wherein sending the first safety signal includes sending at least one signal to activate a visual warning, an auditory warning, haptic warning, and a safety device for the vehicle.

11. The method of claim 10 , wherein the sending the first safety signal to the at least one vehicle system includes sending a signal to initiate pre-charging a head support system.

12. The method of claim 9 , wherein the sending the first response signal to the at least one vehicle system includes sending a signal to initiate at least one of; pre-charging the brakes, deploying a rear facing bumper to an extended collision position, and lowering a body height of the vehicle.

13. The method of claim 8 , further comprising determining a collision from with an object in a forward direction is likely to result from a rear collision.

14. The method of claim 13 , further comprising sending a third signal to at least one vehicle system to prepare for a forward vehicle collision.
