Introduction to ABS

ABS system in car

ABS refers to the anti-lock braking system which is a well known feature in vehicles, especially cars. This feature is for safety purposes. 

As the name suggests, this feature prevents the wheels from getting locked while hard braking. In this manner, this feature helps the driver in having a good control over the vehicle. This also helps in the prevention of risks of skidding or losing control. 

Are you curious to know how you can release brake pressure when your car is off? if yes so check my previous post where I have mention all the steps.

Working or Functioning of ABS

ABS works in a very effective manner and helps in preventing the wheels from getting locked. Below mentioned is the process or the manner in which ABS works or functions:-

Detection of the speed of the wheel

All the wheels of your car come with speed sensors. This, whenever there is a sudden change in any of the wheels, the wheel speed sensor informs this to the ABS. Then, the ABS control module detects the speed of all the wheels. 


After detecting the wheel, if any of the wheels has a possibility of getting locked, the ABS system gets activated for that wheel. This decision is taken by the ABS system in less than milliseconds. The ABS system had the ability to take this decision in such a short time as the ABS control module monitors the wheels and their speed continuously. This module is also known as the brain of the ABS system. 

Working of ABS

Work of Hydraulic Control Unit (HCU)

After the successful activation of the ABS system, this HCU i.e the hydraulic control unit takes action. It is responsible for controlling the brake fluid pressure of the wheel which has a possibility of getting locked. If the wheel gets locked, the ABS system rapidly reduces the brake pressure with the help of HCU. Basically, the main function of HCU is to prevent the complete lock up of the wheel. 

Brake Pulsation

After the HCU gets activated and starts working to control the wheel and prevent it from getting locked, the driver starts feeling a pulsating sensation. This sensation makes sure that the ABS system is working properly and is controlling the wheel. This sensation may be a little annoying for the driver but this prevents the wheel from getting locked. 

Steering Control

By activating the HCU and giving this pulsated sensation, the ABS system controls the wheels and their speed and allows the driver to control the wheel and handle them. In this way, ABS prevents the risks of accidents and losing control. 


Once the driver takes the wheels in his control, the ABS system stops controlling the wheel and handles it completely to the driver. Thus, at the end, this ABS system gets deactivated.
