Adaptive Front-Lighting System
The adaptive front-lighting system (AFS) redirects low-beam headlamps individually in a horizontal direction in accordance with steering angle and vehicle speed. As a result, this system can improve visibility during night-time cornering, ensuring safer driving.
DENSO’s products developed for the world’s first AFS, include:
- AFS ECU that calculates the swivel angle using steering angle and vehicle speed information, as a vehicle turns a corner.
- Swivel motor that focuses the low-beam headlamps in the direction of the turn in accordance with the swivel angle, illuminating the road ahead at a wider angle.
The AFS ECU also calculates vehicle incline using the vehicle height, and controls a leveling motor based on the incline to maintain the headlamp’s vertical axis.
