What is ABS?
Many car owners know everything about ABS. But what about the rest? That is ABS, our article will tell.
Antilock Brake System (ABS) is an anti-lock braking system.
The principle of its operation is quite simple: ABS will not allow complete blocking of the wheels in the process of braking the car, that is, when the car is braked, the wheels will not be blocked and will not go into a skid, which will allow you to leave driving even on roads where there is a small coefficient of adhesion, snow, mud or rain.
The work of the ABS system can be felt by the characteristic vibration of the brake pedal during intensive braking. Release the brake pedal while it is impossible, but it is necessary, on the contrary, even harder to press on it.
The principle of operation of the anti-lock system
Each car has a special sensor system. Some sensors monitor the speed of rotation of the wheels, others - the speed of the car.
ABS consists of:
- Special sensors that are installed on the wheels and register their speed of rotation.
- The electronic unit, which is engaged in data processing.
- A modulator whose function is a cyclical change of pressure on the brake line.
At the time of emergency braking, in a car without the ABS system, the wheels will be locked and it will go into a skid. On the car with ABS, wheel sensors know that the wheels have stopped, and the car itself continues to move, it is at this moment that the wheel sensors transmit a signal that is designed to reduce the braking force on these wheels, the braking system, so that the wheels become unlocked and the car easily avoids drift.
Today, ABS is standard on almost all cars.
Now you know what ABS is in a car!
