Subaru EyeSight™ System Tutorial
Subaru's EyeSight™ is the next great technology in driver assistance safety systems. EyeSight™ integrates a number of technologies that help minimize or avoid collisions with objects in front of the EyeSight™ system. The system integrates adaptive cruise control, pre-collision braking, and vehicle lane departure warning. It can even detect obstacles in front of a parked car to limit the potential of damage in the case of an impact. The EyeSight™ technology will be available in select 2013 Outback and Legacy models, and subsequently on other products in the Subaru line-up.
The Subaru EyeSight™ system will be one of the most affordable driver assistance safety systems available in the United States. Combining safety and convenience features, EyeSight™ uses two charge-coupled device (CCD) cameras mounted inside the car on the upper edge of the of the windshield. Mounting the cameras on the windshield reduces the potential for damage to the system that is more likely to occur in bumper-mounted systems. Processing the stereo images from the two cameras allows the EyeSight™ system to identify vehicles in front, as well as obstacles, traffic lanes, and other objects. The video information is sent to the EyeSight™ computer, which is networked with the car's braking system and electronic throttle control. Traveling under 19 mph, the EyeSight™ is capable of detecting pedestrians in the path of the vehicle and if detected the system will activate in order to mitigate or avoid collision. The EyeSight™ is even capable of bringing the car to a complete stop, in certain circumstances.
Principle of Operation
Sometimes drivers can become fatigued or distracted, causing their reaction
time to a potentially dangerous traffic situation to decrease. The EyeSight™
system is designed to assist or warn the driver in avoiding or reducing the
severity of frontal accidents.
Pre-Collision Braking System
EyeSight's™ Pre-Collision braking system will detect obstacles in the path of the car, and if the driver has not applied the brakes in time, or does not brake appropriately, the system will automatically apply the brakes to help lessen or avoid a potential collision.
Pre-Collision Brake Assist
The Pre-Collision Brake Assist will recognize a potential frontal impact, and alert and assist the driver by applying full braking force when an emergency-braking situation is detected. The Pre-Collision Brake Assist feature enhances Brake Assist found on all Subaru models. Limited to 19 mph or less closing speed difference, it is helpful because many drivers often do not apply full braking pressure in emergency situations.
Pre-Collision Throttle Management
In order to help you avoid accidentally accelerating into a barrier or a vehicle stopped in front of you the EyeSight™ system integrates Pre-Collision Throttle Management. The system restricts the engine output to reduce possible impact force and frontal impact damage, should an object be detected, and will to help prevent injury should the driver mistakenly accelerate when EyeSight™ recognizes an object directly in front of the car.
Lane Sway & Departure Warning
Lane Sway & Departure warning can detect the vehicle's position within the road lane markings and will sound a warning to the driver either when swaying within the lane is recognized, or when EyeSight™ recognizes the potential for the vehicle to unintentionally move out of its lane. The warning can also alert you to erratic driving, such as when the driver is drowsy. This system will become operational after the vehicle exceeds 32 mph.
Adaptive Cruise Control
EyeSight's™ Adaptive Cruise Control system can assist you in maintaining a safe distance from the vehicle ahead of you. Once the driver sets the speed the Adaptive Cruise Control not only regulates that speeds, but also a set distance from the car in front of you. There are three different distances the driver can select from, based on time and speed. The EyeSight™ system then uses braking and monitoring technologies to maintain and regulate the vehicle speed within the flow of traffic.
Lead Vehicle Start Alert
If the vehicle in front of you has moved and the driver doesn't react within several seconds the Lead Vehicle Start Alert will sound. The volume for the alert can be changed or turned off.
Controls and Information Display
The EyeSight™ System is designed to assist not distract the driver, so the controls and information display are primarily positioned on the steering wheel, and displayed on the instrument panel.
