Abstract-This paper presents Anti-Lock Brake System. It is a system which is installed on vehicles to eliminate wheel lockup and prevent skidding. this helps drivers to maintain control during stops on low traction surfaces and in emergency stopping situations. In addition to thedirect benefit of greater directional control, the improved vehicle control offered by ABS reduces the potential for trailer swing-out and jack-knifing of combination vehicles. Moreover, this system has its own practical applications and limitations which are enlisted further Keywords- Anti-lock Brake System (ABS), Hydraulic Control Unit (HCU), Electronic Brake Control Module(EBCM), Electronic Stability Control (ESC), Electronic Brake force Distribution (EBD), Electronic Control Unit(ECU). INTRODUCTION:

commonly known as ABS is used as an antiskid
device in a vehicle. It used to prevent skidding of
wheels while braking when we want to stop the
vehicle or suddenly reduce its speed at any time. It
provides better stability and control over vehicle
while braking at high speed. An antilock brake
system provides a high level of safety to the driver by
preventing the wheels from locking, which maintains
directional stability. A professional driver may be
capable of maintaining control during braking by
pumping the brake pedal which allows a locked
wheel to turn momentarily. Whereas a professional
driver may be capable of modulating the brakes
approximately once per second, ABS is capable of
modulating the brake pressure at a given wheel up to
fifteen times per second. An ABS system does
something else that no driver can do, it controls each
front brake separately and the rear brakes as a pair
whenever one of the wheels starts to lock. ABS helps
stop a car in the shortest possible distance without
wheel lockup while maintaining directional control
on most types of road surface or conditions. If a ABS
system malfunctions, normal braking will not be
affected. Anti-lock braking system is an automobile
safety system that allows the wheels on a motor
vehicle to maintain tractive contact with the road
surface according to driver inputs whilebraking,
preventing the wheels from locking up (ceasing
rotation) and avoiding uncontrolled skidding. It is an
automated system that uses the principles of threshold
braking and cadence brakingwhich were practised by
skilful drivers with previous generation braking
systems. It does this at a much faster rate and with
better control than a driver could manage. ABS
generally offers improved vehicle control and
decreases stopping distances on dry and slippery
surfaces for many drivers; however, on loose surfaces
like gravel or snow-covered pavement, ABS can
significantly increase braking distance, although still
improving vehicle control.
Since initial widespread use in production cars, antilock
braking systems have evolved considerably.
Recent versions not only prevent wheel lock under
braking, but also electronically control the front-torear
brake bias. This function, depending on its
specific capabilities and implementation, is known
as electronic brakeforce distribution (EBD), traction
control system, emergency brake assist, or electronic
stability control (ESC).
Even when applying the full force of braking power,
the vehicle remains under your complete control
thanks to the Anti-lock Brake System. It uses precise
regulation of the...
