Like the first iteration of Eyesight, the revised system utilizes a pair of cameras, each mounted at the top of the windshield on either side of the rear-view mirror. As was previously the case, the cameras work to detect objects approaching the car to warn the driver of a collision.

When an object is detected, the system sounds a warning to the driver. If the speed difference between the two objects is greater than 18.5 mph, Eyesight will trigger a pre-collision brake control system, which works to slow the car. If the speed difference is less than 18.5 mph, the system will actually bring the car to a complete halt.

Subaru's also fitted the latest version of Eyesight with adaptive cruise control. When engaged, the vehicle is kept at a safe distance from other traffic. In emergency situations, the vehicle will be stopped until the car in front begins to move. We've seen other automakers utilize similar systems, but most are tied to laser or radar sensors, not cameras.

It's unlikely we'll see this technology arrive in North America for some time yet, but Subaru plans on rolling the new Eyesight feature into Japanese-market Legacy models this May.
