Anti Lock Breaking System
Introduction

An anti-lock braking system (ABS) is a safety system on motor vehicles which prevents the wheels from locking while braking.

The Anti-lock Braking System is designed to maintain vehicle control, directional stability and optimum deceleration under severe braking conditions on most road surfaces

It does so by monitoring the rotational speed of each wheel and controlling the brake line pressure to each wheel during braking. This prevents the wheels from locking up.

A rotating road wheel allows the driver to maintain steering control under heavy braking

Theory

When the car brakes (normally ) wheels exert a forward force on the street with less than maximum static sliding friction.

If the driver brakes very hard it can occur that the maximum static friction is surpassed and the wheels lose their grip and begin sliding

The amount of traction which can be obtained for an auto tire is determined by the coefficient of static friction between the tire and the road. If the wheel is locked and sliding, the force of friction is determined by the coefficient of kinetic friction. A tire that is just on the verge of slipping produces more friction with respect to the road than one which is locked and skidding . So locked wheels are less effective in stopping on a road.
But in gravel, sand and deep snow, locked wheels dig in and stop the vehicle more quickly. A locked tire allows a small wedge of snow to build up ahead of it which allows it to stop in a somewhat shorter distance than a rolling tire.

When tire does not slip, it will roll only in the direction it turns. But once it skids, regardless of the angle of the front wheels, the vehicle continues to skid in whatever direction its momentum sends it until either the driver releases the brakes

    ABS, also knows as the Anti-lock braking systems, are used for short stops. Usually, when one is stopping short on a slippery rode, they are needed. The road may be slippery due to snow, rain, or ice. When on a slippery surface, most likely ice, the car does not usually move forward, or stop, because the tires have little to no traction due to the wet ice. The Anti-lock Breaking Systems allows for the car to come to a faster stop on ice. It also allows the driver to steer the car while he is coming to a stop. The speed sensors in the ABS inform the system of the cars speed and therefore can detect if the wheel [or car] is entering a situation in which it may lock up. The valves control the pressure of the break by lowering it. On the other hand, the pump raises the pressure of the brake. Inside the car there is a controller, similar to a computer, which controls the speed sensors, the valves, and the pumps. Depending on the number of channels and sensors in the specific system, there are many variations of ABS. A four channel, four sensor ABS is the best because all four wheels are monitored and controlled separately. In a three channel, three sensor ABS, the back two wheels are controlled by only one sensor, while there are two censors for the front two wheels. This system is often found on pickup trucks. In a one channel, one sensor ABS, the same valve controls all four wheels. The ABS systems allows so the driver does not need to pump his or her break manually. Should one encounter a system in which ABS is necessary, the pumps and valves of the systems control this automatically.…

    Brakes are the most important safety feature on any vehicle and play a huge role in all aspects of the car. Since the early 1900’s, there have been many different kinds of brakes invented and manufactured. There are two types of brakes that stuck around to still be used today, they are referred to as drum and disk brakes. Sensors and technology have improved the way brakes are made and functioned today. Although these advances are very beneficial to car buyers, it can become expensive to people who aren’t familiar with changing the brakes themselves. Components of most vehicles brakes are very simple and they are easy to understand for most people. If they are not changed properly, it could lead to negative results.…
