The dynamic bend lighting is achieved by swiveling the low beam depending on the curve radius being negotiated. The projection headlamp is installed in a frame that rotates around the vertical axis. The swivel angle in the range of +/– 15 degrees is designed for curve radii up to approx. 200 m. When entering a curve with a radius of 190 m, if the area illuminated by the low beam is usually around 30 m, this is extended by another 25 m through the new headlamp technology.
Since the light distribution corresponds to the respective steering angle, the driver can recognise the course of the curve early when driving into it and adapt his driving style accordingly. Active bend lighting works with both the low beam and high beam functions and continually adapts to the respective driving speed. While the headlamps follow the steering wheel movement within seconds at high vehicle speeds, the swiveling mechanism works more slowly at lower vehicle speeds in order to distribute the light as required by the driver.
