What Is ABS In Simple Words?
The law has required the use of an anti-lock braking system (ABS) for more than 10 years. How does it work?
After the seatbelts, the anti-lock braking system is one of the most important safety factors for road traffic. It was made mandatory in 2004, but on some cars this system began to be installed since the 1960s.
Why ABS is so important?
The only contact of the car with the road is four small areas of the rubber tire. If one or all of them lose grip, the car starts skidding, and the driver risks losing control. The reasons for this are several, the main one is heavy braking.
In an emergency, an inexperienced driver instinctively presses the brake pedal, causing the car to slide, get out of control, and stop longer. To counter such effects, ABS was invented.
The system automatically prevents the wheels from locking when braking strongly, helping to restore efficient braking and control. As a result, the driver can simultaneously slow down and control, thereby retaining control of the car and avoiding an accident.
How does ABS work?
The ABS system uses sensors to control the speed of rotation of each wheel. If, as the driver brakes, the system feels that one or more wheels suddenly slow down and risk locking, it automatically releases the brake so that the wheel continues to turn before slowing down. It performs this operation up to 15 times per second (an action that can be felt as an impulse through the brake pedal) to provide or restore effective braking and steering.
How to know if ABS is working on the car?
When it works, you feel it like an impulsing movement through the brake pedal. As systems become more complex, they become less felt. With normal driving it rarely comes into effect. This often occurs on wet, slippery roads. If there is a problem with the system, a warning signal appears on the dashboard of the car.
If ABS is activated while driving, the indicator flashes instantly – this is a warning that the tires have lost grip and the system has worked. The indicator goes out as soon as the traction is restored. If it burns all the time, it can mean that there is a malfunction in ABS, and you need to check it at a service station.
It is hardly possible to overestimate the number of lives saved with the help of ABS.
