Subaru announces new ‘EyeSight’ ADAS with CCD cameras

Subaru will introduce its brand new EyeSight driver assistance system on its 2013 Legacy and Outback 3.6R Limited Package models later this year.

Combining safety and convenience features, the Subaru EyeSight system will be one of the most affordable such technologies available in the North American market. Unlike other manufacturers who only introduce this system in top-end models, Subaru’s plans to incorporate EyeSight in its intermediate, mid-size segment will further enhance an already value-packed offering.

EyeSight uses two charge-coupled device (CCD) cameras developed by Subaru. EyeSight is mounted inside the car on the upper edge of the windshield, thus reducing the potential for damage that could occur in bumper-mounted systems, such as radar. The EyeSight system processes stereo images to identify the vehicles travelling in front, as well as obstacles, traffic lanes and other items.

The video information is relayed to the EyeSight computer, which is also networked with the car’s braking system and electronic throttle control. Below speeds of approximately 30 km/h, EyeSight is capable of detecting pedestrians in the vehicle’s path and can activate in order to mitigate or even avoid the collision. Under certain circumstances, EyeSight is able to bring the car to a complete stop, thus avoiding a collision.

Pre-Collision Braking Control and Collision Mitigation

At relative speeds under approximately 30 km/h, EyeSight’s Pre-Collision Braking System can help avoid a potential collision. The system can detect obstacles in the car’s path and, if the driver has not applied the brakes in time, the system can act to slow the vehicle or bring it to a full stop. At relative speeds above approximately 30 km/h, EyeSight will mitigate potential damage from a collision.

Lane Departure and Sway Warning

By monitoring traffic lane markers and lines, the Subaru EyeSight system can detect if the car begins to wander outside the intended lane without a turn signal being used, or if the car begins to sway within the travel lane. Using the turn signal cancels the warning.

Adaptive Cruise Control

Intended for highway use, Eyesight’s Adaptive Cruise Control system can maintain a safe distance from the vehicle in front, braking and/or accelerating the car as needed to maintain the driver-selected target speed and travelling distance. Adaptive Cruise Control is operational from 40-145 km/h and can continually brake until the vehicle stops if the system “locks on” to a vehicle ahead.

Additional EyeSight Benefits

In heavy traffic conditions, EyeSight will also alert the driver when the vehicle ahead has moved if he or she doesn’t react within several seconds. The technology can also help reduce collision damages by cutting the throttle when it senses an obstacle in front, but the accelerator pedal continues to be pushed.

The system is also effective when a driver shifts into Drive inadvertently instead of Reverse when backing out of a parking space, providing the system has been turned on for at least 10 seconds. EyeSight’s stereo camera design provides a detection angle wider than that of radar-based systems.
