Active Defensive Collision Avoidance

If your car is about to be hit by another vehicle, it would be better if it took action to avoid or to

lessen the impact. Disclosed here is a method for a stationary car(s) to avoid or to lessen the

impact of a collision from a moving vehicle. In essence, it is a situational awareness aspect of

the vehicle. That is, if the vehicle is stationary (at a traffic light, due to congestion, a pedestrian

in a crosswalk, etc.), the onboard collision avoidance systems of current vehicles do not detect

any imminent collision and, consequently, take no action. Even Tesla's* autopilot feature does

not appear to handle this situation [1].

When a passive car(s) detects that a vehicle is approaching and determines that this

vehicle's velocity (trajectory and speed) is such that it will likely strike the car(s), the car(s) can

take one or more of the following actions:

1) Move a small distance (based on available space) in a direction opposite to the incoming

vehicle's trajectory, which will allow more time for that vehicle to slow down,

2) Deploy an exterior air bag that will cushion the impact and potentially prevent damage from

the impact. It is noted that there are stationary impact attenuators and Fitch Barriers, but the

attenuators are always deployed and the barriers are part of the roadway.

Envisaged is a 'hive' mentality where all the vehicles are in peer-to-peer communication

with each other, and the group collectively decides on the best cour...
