1.Active High Beam technology
Introduction
A lot of people will not often be the car or on a vehicle in the blind with light shaking. This practice is not only a moral shortcoming, it will cause traffic problems. In order to eliminate the factors driving these unstable, Volvo recently announced a new research initiative headlight technology mdash; mdash; Active High Beam technology.
# 8203; While in accordance with Article 48 of “Road Traffic Safety Law”: traffic lights turn on the road or other illumination preferably should not turn the high beam. Turn on the high beam of the vehicle should switch to low beam lights before the car in front will be 150m, but still people disregard the feelings of others insisted on the use of high beam driving. Wrong use the high beam will cause the front car, opposite the driver instantly blinding, so that driver’s speed and distance perception of decline, down to the width of judgment and so on, following this actual picture may allow you to clearly see that the incorrect use of lights and murder almost no different.
Active High Beam technology and the use of the vehicle located in front of the camera to scan two optical traveling road surface ahead of the front windshield and the pedestrian walking, and thus located within the headlight bezel group, based on the final control let occlusion region of about 1.5 inches to maintain the width of the preceding vehicle, but only the optical scanning camera 15 within a range of the road before the vehicle. # 8203; # 8203;
When the optical scanning camera to the road with a preceding vehicle or object appears to car, headlights located within the baffle set based on the width of the preceding vehicle or a vehicle in the automatic block large lighting lamps within the corresponding region, and the camera continuously scans the vehicle and the leading vehicle, the distance to the car, and continuously control the position of the shutter flap area, play to reduce interference lights of the preceding vehicle and the driver’s line of sight through the light shielding effect until the front of the vehicle or a vehicle inThis vision of the driver exceeds the vehicle will be canceled blocked.
In the actual road conditions, not only to the front of the vehicle and running, walking pedestrian will appear, many people have been in the nighttime glare to the vehicle lights and short experience blindness. If at this time appeared in front of potholes or obstructions, accidents can easily occur. When Active High Beam technology to detect when a pedestrian street, the lights will automatically adjust the height, so that the light is always lower than the pedestrian head, avoid direct light pedestrian eye. This feature will also vary from the vehicle with a pedestrian, to constantly adjust the height of the light, to achieve both protection of pedestrians without losing the effect of the illumination range.
