A Software and a Hardware Interface for Reducing the Intensity Uncertainties Emitted by Vehicular Headlight on Highways

This paper proposes a hardware and a software interface for reducing the effects of Headlight glare. It proposes a Fuzzy Sensor and a Fuzzy Controller that uses fuzzy rule based design approach to reduce the Headlight glare emitted by the oncoming vehicles during night on the Highways. This in fact reduces accidents and puts the driver of the oncoming vehicle in a safety zone which might jeopardize the oncoming driver’s visibility. In the conventional vehicles the illumination is adjusted manually by the driver. The proposed approach has the hardware circuit fit on to the Windshield, which provides ambient light source to oncoming vehicle, there by not producing blinding effect on the vision of the driver . This Hardware has to be fitted on to all the vehicles, so that it reduces the occurrence of accidents. Microcontrollers are usually designed to interface to and interact with electrical/electronic devices, sensors and high-tech gadgets to automate systems. Microcontrollers are used for automated decision making. The PIC microcontroller has been used which reduces the intensity of light if it goes beyond tolerable limits, affecting the driver’s vision. The concept of Fuzziness has been applied to the sensor and the Controller. The light intensity of the oncoming vehicle is received by the Fuzzy sensor. This input light intensity is fuzzified and checked for the tolerance limit. If this does not lie within the tolerance limit, the sensor passes it to the Fuzzy controller which converts it to an ambient light source and then on defuzzifying the output. The software has been developed using MATLAB.
