Subaru’s double vision prevents accidents | The Car Tech blog - CNET
Subaru’s new EyeSight system, which will first be available on the 2013 Legacy and Outback, uses two cameras to monitor what is out in front of the car. These cameras use stereo processing to determine the distance of other cars or objects ahead. They also can recognize lane lines.
These sensors enable a whole raft of driver assistance features. Collision prevention and mitigation can hit the brakes if the cameras detect an imminent collision with a pedestrian, car, or object. Subaru says that at speeds under 19 mph, the system can brake the car quickly enough so as to avoid a collision. At greater speeds the automatic braking will reduce the impact.
