Antilock Brake System

Ongoing advance in car brake systems have resulted in reliable systems contributing to increased car safety.

In normal driving conditions, conventional brake systems (CBS) can provide effective and fast stopping for the vehicle. However, in the following driving circumstances, braking can result in locking of wheels which in turn leads to lack of steerability and slipping of the vehicle:

     1-      Slippery and wet roads

     2-      Frightened reaction of the driver

     3-      Errors of other drivers and pedestrians

Antilock Brake System

 

Ongoing advance in car brake systems have resulted in reliable systems contributing to increased car safety.

 

In normal driving conditions, conventional brake systems (CBS) can provide effective and fast stopping for the vehicle. However, in the following driving circumstances, braking can result in locking of wheels which in turn leads to lack of steerability and slipping of the vehicle:

 

     1-      Slippery and wet roads

 

     2-      Frightened reaction of the driver

 

     3-      Errors of other drivers and pedestrians

 

The above are among the issues for addressing of which the Antilock Brake Systems have been invented.

 

History of ABS systems

 

The first instance of ABS system was designed for trains in 1900. After the Second World War, ABS systems were used for Jet planes. In 1960s, as brake systems of automotives were being revolutionized, brake manufacturers started to develop and use ABS systems for luxury cars such as Mercedes Benz.

 

Operational principles

 

When brake pedal is pressed with excessive force, there is the possibility that tires decelerate with a higher rate than the car itself. This leads to slipping of tires on the road surface. A way to prevent this is to prevent locking of brakes when the threshold of slipping is detected. This is exactly what the ABS does. At normal braking, ABS has no interference in the operation of the brake system. However, when brakes are applied with excessive force, ABS allows brakes to operate only until the threshold of locking of wheels. When possibility of slipping is detected for one wheel, ABS removes brakes pressure for that wheel. When this risk is removed, the brake fluid is pumped to that wheel again and this cycle is repeated so that deceleration is accomplished without slipping.
