Subaru Eyesight - Second Generation

Subaru has released details of a second-generation upgrade to its camera-based EyeSight driver assistance system, which was introduced on the 2013 Legacy and Outback.

New features include colour stereo cameras that with approximately 40% longer and wider detection range, brake light detection and the ability to fully function when the speed differential between vehicles is up to 54 km/h, rather than 34 km/h.

The current generation Eyesight system earned a "superior" rating by the Insurance Institute of Highway Safety (IIHS), the highest rating given by the IIHS, when it conducted it first test of accident avoidance technology last year.

According to Subaru, research shows that more than half the buyers who have purchased the EyeSight system say that it has helped avoid a collision.

Currently available only on Legacy, Outback and Forester, its availability will be expanded to additional models, the company says.

The new Eyesight system, which uses two colour cameras, is said to function more smoothly and have a quicker reaction time.

The cameras are mounted inside the car on the upper edge of the windshield and the size of the housing has been reduced 25% for the new system.

The EyeSight system processes stereo images to identify vehicles traveling in front, as well as obstacles, traffic lanes and other objects, including pedestrians.

The video information is relayed to a computer, which is networked with the car’s braking system and electronic throttle control and can activate them to mitigate or avoid a collision, including bringing the car to a complete stop under certain circumstances.

The Eyesight system integrates adaptive cruise control, pre-collision braking and vehicle lane departure warning.

At relative speeds below 54 km/h, its Pre-Collision Braking System can apply the brakes, if the driver has not done so to slow the vehicle or bring it to a full stop.

Pre-Collision Braking is always on in the background to act as a second set of eyes for the driver. It can be turned off temporarily for off-road or rough road travel.

Lane-departure warning monitors traffic lane markers and lines and can detect if the car begins to wander outside the intended lane without a turn signal being used, or begins to sway within the travel lane. Using the turn signal cancels the warning.

Adaptive Cruise Control is intended for freeway use and can maintain a safe distance from the vehicle in front, braking or accelerating the car to maintain the driver-selected target speed and traveling distance. It can bring the vehicle to a full stop if the system "locks on" to a vehicle ahead.

Adaptive Cruise Control can also assist the driver in "stop and go" traffic by maintaining distance from the vehicle ahead.
