Volvo Lights The Way


Here’s an interesting new development from the Swedish car maker.  Three of the six new cars that Volvo are showing at the Geneva Motor Show can be optionally fitted with their latest innovation to make driving at night a much safer experience. Volvo, of course, have always been at the forefront of safety and this new lighting system follows that lead.

The Active High Beam Control allows the driver to use high beam all the time because AHBC has an ingenious mechanism that prevents on-coming drivers from being dazzled because a specific area is shaded (see the image). Amazing. This makes redundant the need to switch to low beam when encountering traffic from the opposite direction.

The benefits of this include the ability to ‘see’ into the surrounding traffic area outside of the shaded area revealing hazards that might otherwise be missed on low beam. Unlit parked cars, pedestrians and cyclists will be more visible. This technology is bound to make motoring safer in the dark as the driver isn’t constantly having to flick the beam stalk and can concentrate on what’s really important – good driving.

This is cutting edge auto science. When a car approaches – or when your car catches up with a slower vehicle – the system shades out only as much light as is needed from the beam. AHBC works by utilising the camera located by the driver mirror which is already working with the collision technology and auto-brake system. It is so accurate that the on-comer will be ‘framed’ with only a 1.5° margin.

The control unit instantly relays the information to an ingenious projector module fitted in the Xenon headlamp. This in turns activates a tiny cylinder with metal pieces of differing sizes which deploy to the effect described. It works with two-wheeled vehicles as well, so owners won‘t be blinding motor cyclists. The AHBC will be available on the new Volvo S60, V60 and XC60. The cars will be introduced at Geneva along with three other new cars the V70, XC70 and the S80.

There is an argument which says there is simply too much technology on cars these days but it is hard to argue against a safety feature like this.
