Anti-Lock Braking System



Every driver sooner or later finds himself/herself in a situation where an emergency braking is necessary.

Anti-lock Braking System also known as the anti-skid braking system (ABS) is an automobile safety system which prevents the locking of wheels during braking and avoids uncontrolled skidding.

It is an active safety feature designed to help the driver to maintain better steering control by preventing wheels from locking up during an episode of heavy braking.

ABS uses wheel speed sensors to determine if one or more wheels are trying to lock up during braking. If a wheel tries to lock up, a series of hydraulic valves limit or reduce the braking on that wheel. This prevents skidding and allows you to maintain steering control.

To understand this in a better way lets us take an incident:

When you are driving your car on a highway and suddenly an obstacle comes in front,  you will definitely apply brake with full power. This will lock the wheels of your car and your car will start skidding on the road. Also, during skidding, you will lose your steering control and unable to move the car in the desired direction in which you want. Finally, you hit that obstacle and meet an accident.

It is in these situations where ABS(anti-lock brake system) allows the driver to maintain better control of the car under hard braking.

How does ABS make this happen? Let's look at its components:

Speed Sensor – Speed sensor will figure out whether the wheels are about to lock or not to stop it from happening.

Controller – It is something like a computer. When the sensor tells that wheels are about to lock, it processes that information and orders the braking system to not apply all the pressure at once but in quick successions.

Valves - All that valves do is open and close. They open and close in quick successions to not let all the pressure reach the wheels at once.

Pump - When valves release pressure to apply the brake, the pressure has to be applied again. Who does that? You guessed it. Pump.

Without ABS system, even a professional driver can fail to prevent the skidding of the vehicle on dry and slippery surfaces during sudden braking.

ABS would benefit drivers in a variety of fairly common situations, including the following:

·         A vehicle suddenly veers in front of you, forcing you to brake and swerve.
·        An animal jumps onto the road and you must brake and steer to avoid it.
·       Bad weather makes the roads slippery, making wheel lock more likely when you must brake to stop.

So essentially, the anti-lock braking system does exactly what it says on the tin - having ABS in your car should prevent the wheels locking as you brake, giving you more control and allowing you to steer.
