Antiskid braking system
The antiskid braking system is often referred to as an Antilock braking system and abbreviated as ABS. It is a chunk of protection instrument that restricts the wheel disc of an automobile from shutting up under crisis, anxiety, or cruel stopping conditions. In case of unexpected stopping, there is a probability of a sudden loss of grip between the vehicle tire and the pavement, which causes the vehicle to slide. In the unmanageable condition, the circumstance becomes inferior. In the meantime, the automobile carries on to move and the forfeit of hold may result in the pilot leaving control over the vehicle steering, which results in an accident. So the ABS has come up with the solution to the problem.
The greatest advantage of modern ABS is which allows steering even the brake is applied, which gives more control over the automobile in case of application of the immediate brake. It remarkably increases braking distance and improves the control of steering. Even an expert driver will go wrong in preventing the slip-on slip and dry surfaces while a sudden brake is applied. With ABS the normal person can able to get better steering control when a sudden brake is applied.
ABS mainly works on the concept of limit braking and rhythmic braking. It is a technique followed by the driver to apply the brake and release the brake before stopping the wheel completely. It is done rhythmically to prevent it from locking the steering and stop slipping of the vehicle. The Antilock braking system will automatically do this by cadence braking and prevent the wheel from securing and drifting.
To realize this further, when you are driving a motor vehicle on an expressway, suddenly found an obstruction in front of you, and applied the brake with full power. If the motor vehicle is without ABS, it will lock the steering control of the wheel, unable to turn in the desired direction and the vehicle will start to slip leading to an accident. With ABS in the same situation, the wheel will not be locked and there won’t be any slipping and also the driving has control in changing direction and avoids an accident.
The ABS has an electronic control unit (ECU) that measures the signal from the wheel speed sensors. As the brake is applied all of a sudden, the wheel will decelerate fast and comes to rest. This is identified by ECU, the fluid valve closes, the pressure to the brake pad reduces and the wheel is prevented from stopping. Now the wheel once again accelerates, sensed by ECU, the valve opens, pressure is applied to the brake pads, speed reduces and the wheels try to stop. When a driver applies the brake suddenly, this rhythmic process of applying the brake and releasing the brake by ECU will occur 15 times in a second. This feature of ABS prevents the wheel from locking and allows the driver to steer the vehicle.
The antilock braking system is an indispensable protection technique in contemporary vehicles without which it would be hard to avoid accidents under emergency braking situations. Along with other safety control features ABS has saved numerous souls on roadways.
