INTRODUCTION It is a system to increase a vehicle driver's visibility in darkness or poor weather beyond the reach of the vehicle's headlights. In this system Light waves [infrared (IR) ] are emitted by source ; a special cameras. collect small amounts reflected light and amplify it to generate display on cluster. These system are currently offered as optional equipment on certain vehicles.

PRINCIPLE OF OPERATION Night Vision Technology in Automobile Works on two Phenomenon's. 1)Active Illumination Imaging

2)Thermal

ACTIVE ILLUMINATION This system can detect pedestrians up to four times farther than the typical headlight range even in penetrating dense smoke. It actively detects people near the roadway, highlighting potential hazards and allowing drivers to have more time to react to them. Its high beam illumination warns the pedestrians as well.

THERMAL IMAGING Thermal imaging is a heat-sensing technology that can see in complete darkness using temperature difference. Electrical impulses are sent in the form of temperature values to an image signal processor that turns them into video data for presentation on a display.

CAR WITH NVS MECHANISM

WORKING Systems use an LCD that's mounted on the dash, in the instrument cluster, or integrated into the head unit. The front thermographic sensors detects the heat and processes the thermograms to display images on LCD. The IR sensor attached in vehicle's grille illuminates very high beam.

REPRESENTATION

ADVANTAGES OF NVS Reduce Accidents Greater Range of About 300meters or 1000 feet. Can be Switched ON/OFF and doesn’t effect the driver Style. Works in almost every weather conditions.

DISADVANTAGES OF NVS Higher cost of process. Large quantity of costly and complex equipment . Works very poor in warm weather conditions. Large sensors are required .

Audi , BMW uses Thermal Imaging.

PRESENT

DAY A P P L I C AT I O N

Mercedes-Benz uses Active Illumination.

WHAT NEXT ?? FUTURE SCOPE Vision System + GPS Navigation = Driverless vehicle

CONCLUSION “ The innovation and implementation of night vision system has a great impact on automotive session such as saving many lives from death reducing accidents at night. ”
