Media members tested EyeSight's precollision braking and precollision throttle management technologies on a 2013 Subaru Legacy cheap hawaii plane tickets during drives at Michigan's Willow Run Airport. The Legacy's target was a Subaru Outback image superimposed on foam blocks.
Subaru 's new EyeSight driver-assist system can help prevent a rear-end collision and/or other incidents via engaging one or more of seven technologies: precollision braking, precollision brake assist, precollision throttle management, lane-departure warning, lane-sway cheap hawaii plane tickets warning, adaptive cruise control, and lead-vehicle start alert.
cheap hawaii plane tickets "EyeSight is a supplement, not a substitute for the driver," cheap hawaii plane tickets David Sullivan, Subaru of America's Cross Car Line Planning Manager, said during a media briefing in September at the Willow Run Airport in Ypsilanti, MI.
EyeSight scans horizontally with a forward cheap hawaii plane tickets range of about 260 ft (80 m) as well as laterally every 0.1 s. From the vehicle's center line, the black and white cameras have a 25-degree angle of view and a 13-degree upward viewing cheap hawaii plane tickets angle. The system needs a 20 mph (32 km/h) speed differential—essentially 2.5 s—to recognize an object.
"By comparing the left camera image with the right camera image, EyeSight determines the distance to the vehicle or obstacle in front. The cameras need contrast in the vertical surfaces to see in the daytime or nighttime. But in order for an obstacle to be detected at night, it must be within the headlight pattern," Sullivan told AEI .
"There is only one situation in which EyeSight will override what the driver is doing. If the vehicle is heading straight toward an obstacle and the system senses that there will be a collision—even cheap hawaii plane tickets if the driver is already braking—the system will apply brake assist to ensure that the obstacle is not hit or that the collision cheap hawaii plane tickets is mitigated as much as possible," Sullivan said about the system programmed to recognize vehicles, motorcycles, cheap hawaii plane tickets bicyclists, pedestrians, and other objects.
The driver can disengage precollision braking for off-road operation, but the system defaults to an active feature each time the car is started. The system also shuts down temporarily to reset whenever three consecutive instances of precollision braking occur if uninterrupted by a vehicle restart.
Precollision throttle management occurs if the driver depresses the acceleration pedal before the vehicle in front has moved. The technology is designed to prevent a rear-end collision cheap hawaii plane tickets during a right-hand turn if the vehicle ahead does not follow through after an initial move forward.
Adaptive cruise control, operational up to 90 mph (145 km/h), enables the driver to use a steering wheel switch instead of foot pedals to keep a safe distance from the vehicle ahead during an expressway cheap hawaii plane tickets cruise. The distance between vehicles varies, depending on the setting and speed.
cheap hawaii plane tickets Lane-departure warning provides a visual and audio alert if the vehicle strays outside the lane at speeds higher than 32 mph (52 km/h). The system can be turned off, and turn-signal usage negates the warning.
"Heavy rain or snow temporarily disables EyeSight, cheap hawaii plane tickets but if that occurs the driver will get a visual and audible alert. The cameras also are unable to see around curves, so attempting to use adaptive cruise control on winding roads could result in false warnings and braking," Sullivan said.
The first-generation of EyeSight launched in Japan on 2007 MY Subaru vehicles. Second-generation EyeSight debuted in Japan with the 2011 MY, followed by Australia in the 2012 MY and then the U.S. and Canada in the 2013 MY.
