New technologies improve a illumination of roads. An example of this is the glow in a dark street signs or street lights,that light up at the sight of the car. Now added a new technology company Vauxhall / Opel of Concern General Motors. The system changes direction of the light of headlamp on the driver’s view.
Existing adaptive lighting AFL + (Adaptive Forward Lighting) with different modes of operation depending on the traffic conditions will be supplemented by the new lighting system based on matrix of LEDs, which analyzes the light sources from oncoming cars and off individual LEDs in the matrix group to avoid dazzling other road users. The development of technology for tracking the movement of the driver’s eye lasts almost two years. The system not only controls the direction of light rays, but also their capacity.
The system uses a camera which is focused on the points on the driver’s face, such as eyes and nose. By landmarks determined line of sight. Additionally, the driver’s eyes scanned the peripheral infrared sensors and the central photodiodes more than 50 times per second in the dark. Vauxhall / Opel has optimized the system, increasing the speed of the camera and reducing turnaround time. This has improve the response of headlamp. According to the developers, drive of headlamp instantly respond on the horizontal and vertical planes.
The company has also decided the problem of random motion of light rays when the driver shakes his head from side to side. For this purpose was created the special algorithm which delays the response time and smoothes the result of movement of the light beam.
Vauxhall / Opel says,that the lighting control system with the help of sight suitable for any driver and does not require calibration. Unfortunately, it is still in the stage of the research project and will not be soon. But the lighting system based on matrix of LEDs is expected to be submitted within the next 18 months.
