ABSTRACT

In todays world, braking is the

most important system in

an Automobile

!rakes are energy "on#ersion

de#i"es, whi"h "on#ert kineti"

energy o$ the #ehi"le intothermal energy

In Antilo"k !raking %ystem, we "an pre#ent thelo"king o$ the wheel and hen"e skidding, using an

Ele"tro Me"hani"al &ontrol %ystem

INTRODUCTION

In re"ent years, with ad#an"ement

in design ' te"hnology, is" brakes

are $ast repla"ing drum brakesA!% was rst de#eloped $or

Air"ra$ts braking system but

soon started repla"ing the "on#entional braking

system in tru"ks and "arsRe"ent impro#ements in A!% allows to pre#ent

wheel when a""elerated on wet or slipperysur$a"e

OPERATION PRINCIPLE

*+imiting the pressure to any

wheel whi"h de"elerates too

rapidly is the basi" prin"iple employed in A!%

A speed sensor is used $or

measuring the speed o$ the

wheel and sends it "onstantly to the "omputer

epending on the initial brake pressure and the speed o$the wheel, the "omputer modulates the brake pressure as$ast as $teen times per se"ond

CONCLUSION

!e"ause o$ its role in pre#enting the wheels $romlo"king and

better steering "ontrol during braking, Anti5lo"k!raking %ystem

should be made mandatory $or all #ehi"les
