Smart Headlights

German engineers are working on ways to make driving safer by optimizing headlight illumination based on the driver’s line of sight. The eye-tracking system uses a simple webcam to detect subtle movements of the nose and eyes, and utilizes complex algorithms to convert the data into commands that adjust the position of the headlights. Peripheral infrared sensors enable the system to scan the driver’s eyes even at night.

Electronically controlled actuators instantaneously move the headlights horizontally or vertically depending on where the driver is focused. However, a sophisticated delay algorithm is employed to compensate for natural and unconscious reflexes in which a driver’s eyes move from one focal point to another.

The system also includes an LED-matrix lighting system that will be programmed to adjust lighting levels based on a wide range of road conditions including adverse weather, pedestrian areas, city, country or highway driving. In addition, the system deactivates individual LEDs within the matrix when light from an oncoming vehicle is detected. This prevents “blinding” an approaching driver while still illuminating the rest of the road.

The new adaptive lighting system is scheduled for introduction within 18 months.
