The Full form of ABS is Anti-lock Braking System. An ABS is a safety and anti-skid braking system used on aircraft and on land vehicles, such as motorcycles, cars, buses, and trucks. It prevents the wheels of a vehicle from skidding and locking up when breaks are applied during an emergency stop. This system allows the wheels to maintain tr-active contact with the surface of road. When a driver encounters a sudden obstruction and applies breaks, the wheels of the car don’t lock up and it moves in the direction of the wheels as turned by the driver so that it does not crash into the obstruction.

 

ABS is an automated system that uses the principles of cadence and threshold braking, techniques which were practiced by skilled drivers before ABS was widespread. ABS operates more effectively and at a much faster rate than most drivers could manage. From the time ABS was introduced in production vehicles, such systems have become increasingly effective and sophisticated. Modern versions of ABS in vehicles may not only prevent locking of wheel under braking, but may also change the front-to-rear brake bias. This latter function, depending on its implementation and specific capabilities, is known variously as traction control system, electronic brakeforce distribution, electronic stability control (ESC), or emergency brake assist.
