Adaptive front lighting systems (AFS) redirect low-beam headlamp units individually in a horizontal direction in accordance with the steering angle and vehicle speed. As a result, these systems can improve visibility during the night in hilly roads, ensuring safer driving.
We are collecting data about the speed of a vehicle, steering wheel rotation, inclination of a vehicle with respect to horizontal position and humidity using sensors and accordingly turning the headlight in horizontal direction and controlling switching on or off of auxiliary lights automatically. Currently, we are working on the steering wheel measurement module and the inclination module. We are using quadrature incremental encoder to measure the rotation of the steering wheel and threshold angle inclination sensor to measure the inclination. These sensors are interfaced with AT89c5131 microcontroller. It controls the motors to turn the headlight and the auxiliary lights on the basis of the data from the sensors.
