Development of an Adaptive Mobil Front-Lighting System Using Multi-Functional Sensors

Abstract:

The main purpose of the paper is using multi-functional sensors to detect the vehicle attitude (the tilt angle of vehicle), and many other vehicle information. Combining all the information, the adaptive front-lighting system can achieve the real-time control of the pitman arm and yaw angle for automobile headlight system. The feasible control methodology could highly enhance the safety of driving and electronic additional value in automobile industry. In the paper, various conditions of HID (High Intensive Discharge) headlight system could be controlled, such as the control of pitman arm and yaw angle, are widely discussed. In the pitman arm angle control, we use G-sensor to detect the unbalanced vehicle caused by load, rugged road, uphill and downhill. Finally, combining the velocity obtained from the ECM (Engine Control Module), the leveling motor control for headlight pitman arm angle real time and adjust will be realized. On the other hand, we use the potentiometer and micro switch to sense the direction and quantity of steering wheel angle, the swivel motor control for headlight yaw angle real-time adjustment is completed.
