BMW - Adaptive Xenon Light

By

BMW's Adaptive Xenon Light is an interesting piece technology that is derived from high-end cars, for use on their top-of-the line touring bikes. These headlights use a bevy of sensors to measure the bike's pitch, roll, and cornering angles, and level accordingaly, so as to evenly light up the road. This offers improved visibility for the rider in low-light conditions, thereby improving safety 

 

Working:

According to BMW Motorrad, this how the system works: The headlights consist of a centred, swivelling xenon projection module with reflection mirrors. Height sensors on the front and rear wheel suspension supply data for permanent headlight levelling. Thanks to pitch levelling, the headlamp can always illuminate the optimal, predefined area on straight roads, irrespectively of the riding mode or laden state.

Self-levelling mechanism:

The adaptive headlight also features a step motor that converts the standard static reflection mirror into a swivel unit. The mirror is then swivelled over an axis as a function of the inclination, compensating for the vehicle's roll angle. The dipped beam therefore experiences compensation for both inclination and pitching. Both movements are superimposed so that illumination is directed into the corner. This results in a considerably improved illumination of the road in corners and therefore a huge boost to active riding safety. The vehicle's inclination is determined via a sensor box installed at a central location.
