The renewed Active High Beam Control makes it possible to use high beam continuously thanks to an ingenious mechanism that prevents dazzling of oncoming drivers.
Driving at night presents car drivers all over the world with challenging conditions. “Our aim with the renewed Active High Beam Control technology is to enhance visibility in the dark by making it possible to use high beam permanently, without having to switch to low beam when meeting or catching up with other cars,” says Prof. Lotta Jakobsson, Senior Technical Specialist Safety at Volvo Cars Safety Centre.
The main advantage of Active High Beam Control is that the traffic environment outside the shaded area is still illuminated by the high beam. This improves the driver’s chances of detecting objects at the side of the road, such as parked cars, unprotected road users and animals.
“The technology makes driving at night more comfortable and safe. It also makes it easier to focus on the driving and is an excellent example of our Designed Around You approach, always focusing on features that really make a difference to the customer,” says Lotta Jakobsson.
When an oncoming car approaches or when catching up with another car from behind, the system helps to prevent dazzling of the other driver by shading out only as much of the beam as necessary.
Active High Beam Control uses the camera already used for the detection and auto brake systems located by the rear-view mirror at the top of the windscreen to identify the other vehicle and the area that needs to be shaded. The technology is accurate enough to frame the chosen object with only a 1.5° margin.
The control unit relays the information to an ingenious projector module mechanism integrated into the headlamp. A tiny cylinder with metal pieces of different sizes allows the possibility of shading just as much of the beam as necessary.
The Active High beam Control, which also works for motorcycles ahead, features Xenon lamps. The technology is active at speeds down to 9mph. It will be available in the Volvo S60, V60 and XC60 from spring 2013.
The six new cars in Volvo Cars model range – the Volvo S60, V60 (including V60 Plug-in Hybrid), XC60, V70, XC70 and S80 – will also be on display in Geneva.
