ABS full form is an anti-lock braking system. The requirement to increase vehicle safety and control when braking was the main driving force behind the invention of ABS. Before the invention of ABS, when a driver applied abrupt, forceful braking, the wheels may lock up, potentially causing the car to slide and lose control. ABS keeps the wheels from locking up when the vehicle brakes to retain steering control and lessen the chance of skidding. ABS does this by quickly varying the brake pressure on each wheel, preventing full wheel lockup while applying adequate braking power.
