How Does Anti-lock Braking System (ABS) Technology Works? Part I

The Anti-lock Braking System (ABS) in your cars help you steer smoothly by engaging traction in your wheels. It effectively prevents the wheels from locking up and allowing the drivers to steer safely striking out the chances of skidding or collision.

But the biggest elephant in the room that we need to address is “How Does ABS Works”. Well, the working principle and mechanism are pretty much simple to understand, especially when the experts at BP Auto Spares India, Largest Leyland Spare Parts Dealers are here to guide you throughout.

First, let’s have a look at the various components of ABS.

4 Main Components of Anti-lock Braking System (ABS) Technology

Speed Sensors: The only way to make out if the wheels are about to lock up is when the vehicle is equipped with some kind of sensors to alert drivers of the situation. The speed sensors which are positioned at each wheel and often in the deferential, serve this useful information. Speed sensors also gauge the speed of each wheel and examine required acceleration and deceleration of the wheels.

Valves: The valves are there in a vehicle to help regulate the steady flow of air pressure to the brakes during the whole ABS process. The brake line of each brake has a valve installed in it.

  • The first valve allows the pressure from the master cylinder to be supplied to the brakes.
  • The second valve in the brake line remains close in order to restrict the supply of pressure from the master cylinder to the brakes.
  • The thirst valve partially releases the pressure from the master cylinder to the brakes.

Pump:  Valves are the ones that release pressure from the brakes, so there has to be something to put that pressure back in. This task is accomplished by the pump when a valve decreases the amount of pressure in a brake line, the pump helps to put the pressure back in.

Controller: The ABS has two control units, Electronic control unit and hydraulic control unit, ECU controls the brake pressure according to the data that is received from the speed sensors and HCU controls the brakes by elevating the hydraulic pressure to reduce the braking power.
