What is the function of the brake abs of the car and how to use it?

Basic structure: its structure compared with the traditional braking system is mainly in each wheel increased speed sensor and ECU electronic control unit and brake pressure regulator.

Working Principle: After the brake is pressed, the wheel stops rotating, and will be used to brake the car with sliding friction resistance, at this time, the speed sensor will pass the wheel speed to the ECU, the ECU thus control the brake pressure regulator to regulate the pressure of the brake pump, which allows the wheel to roll up again to provide the maximum rolling resistance. Repeatedly, the tires provide the maximum rolling resistance when braking, so that the car is smoother, shorter distance to a stop (if there is no ABS tires are stepped on after the death is likely to appear the whole car skidding, tail situation, very dangerous). Before ABS appeared, the old driver is to use the "point brake" to faster, safer stopping.

So, the role of ABS is to make the car encountered an emergency need to stop, to achieve the shortest braking distance, and the whole process does not appear sliding friction, to ensure that the car is more stable, so the ABS system is also known as electronically controlled anti-locking system.

ABS is simply an anti-lock system.

That is to say, the anti-lock braking system can improve the safety factor of the vehicle emergency braking when driving.

Because what?

Because there is no ABS car, the car in case of emergency to take emergency braking, prone to tire locking, that is, the steering wheel can not turn, so the risk factor will be increased, it is easy to cause serious consequences.

The principle of the ABS system is to use the four wheel sensors to sense the wheel's rotation speed, but the brakes are very strong wheel holding dead not turn, the sensors will give the computer signals, the computer will hold the dead wheels to reduce the braking force, so that the wheels to resume rotation, the wheels will rotate after the braking force will be restored, the wheels will be held dead again, in such a cyclic role, the wheels will be a state of the brakes to the state of the brakes, this point of braking can be used for braking, this point of braking can be used for braking. Braking, this point brake can reach more than 13 times per second, so we can use the maximum braking force to brake, but there will be no wheel holding, side slip, out of control problems, so now ABS has been the standard automobile passive safety configuration.
