Fuzzy control of head-light intensity of automobiles: design approach

Road accidents are increasing and the rate is alarming in India. Around 70% of the accidents take place in the night. The vision and the traffic in the night need to be further augmented with facilities such that the vehicles provide illumination in a way that it does not blind the driver of the oncoming vehicle. In contemporary automobiles, intensity control of head lights is provided and the vehicle can be maintained at two intensity levels. Uncontrolled beam intensity is a regular feature since maintaining the intensity is at the discretion of the driver himself and not an integral part of the vehicle electronic system. To increase the effectiveness of the controller we propose an automated fuzzy controller which provides illumination in such a way that glare to the oncoming driver is minimum. The performance of the proposed controller is evaluated by experimentation
