Adaptive Headlight technology

Just saw this demonstration, it's an interesting idea. I would like to see how the lights react with same-direction traffic on either side of the vehicle.

The Adaptive Headlights cast their beam in the direction of the curve and ensure better visibility and more safety during night drives on winding roads.

Sensors measure speed, steering angle and yaw (degree of rotation around the vertical axis). Based on this information, small electric motors turn the headlights left or right so the beam falls on the road ahead, guiding you into the bend.

Headlight beam throw control (a model-specific function) means the front headlights are raised at high speeds and lowered at slower speeds, which results in a wider beam for inner-city driving.

The adaptive headlight range control (a model-specific function) takes into consideration the vertical curve of the road. The headlight beam throw control is lowered when driving over a knoll and raised when the vehicle is in a dip.

The result: every single curve is illuminated and the oncoming traffic isn't dazzled unnecessarily. Driving at night is even safer, particularly when visibility is poor.

Adaptive Headlights are only active when the vehicle is pulling away. They stay switched off when the BMW is in reverse and when the steering wheel is turned to the left while the vehicle is stationary (e.g. when pulling out of a parallel parking space) to avoid dazzling oncoming traffic.

Adaptive Headlights are complemented by cornering lights. These are automatically activated at speeds of up to 70 km/h and improve visibility in the immediate vicinity of the vehicle, which is useful when driving along hairpin bends, turning or parking.
