INTRODUCTION

• The highest fatal traffic accident rate occurs on curved roads at nighttime due to the late recognition of objects in the traffic zone.

• The static headlamp just provides certain illuminating fields for drivers in the nighttime and is insufficient to serve on curved roads

• In order to provide enhanced nighttime safety measures this work aims to design and build a prototype of steerable headlights by adapting a conventional static headlamp.

OBJECTIVE

• To design and build an Adaptive Front Lightening System prototype that will modify an existing fixed headlamp with a very close eye on cost and reliability.

• To improve adequate visibility at the curved path.• To improve driver’s comfort at night time.• Change the vehicle’s condition static to dynamic.• To increase road and pedestrian safety.

COMPONENTS

• STEERING SYSTEM• SENSOR BLOCK– Potentiometer– Analog-Digital Convertor

• MICROCONTROLLER• ACTUATOR BLOCK– Servomotor– Headlamps and Headlamp Casing

STEERING SYSTEM

• Steering system is used to convert rotary movement of steering wheel into angular turn of the front wheels.

• As the steering shaft rotates(taking corners), it will turn the axle of potentiometer & therefore vary the voltage input.

POTENTIOMETER

• Due to rotation of the shaft of potentiometer it supplies variable voltage to microcontroller.

SERVOMOTOR

• It is a type of motor which rotates in both the clockwise and counter clockwise directions.

• It consists of 3 wires: red, black, and blue. The red and black are the positive and negative power supplies, whereas the blue is for signaling.

HEADLAMPS• Headlamps are mounted

on servomotor.• The casing of headlamps is

made light in weight as much possible (such as Aluminum metal) to rotate it effectively.

ADVANTAGES

• Better visibility and identification of obstacles on curved path

• Improved Comfort• Ease of handling• Components are available easily in market

FUTURE SCOPE

• In future we can add more functions to an adaptive front light system such as to increase the intensity of light of front headlamps in rain, fog etc..

• Functions can be made rather simple but still effective in there basic version and will probably easy to sell because they are not very well covered by the traditional vehicle illumination system.

LIMITATIONS• Economical and Technical Limitations• Designing limitation such as space provided to

rotate the Headlamps• International differences in regulations on

what the designer could and couldn’t do• Can’t tell about customer reviews• Lack of innovation
