What is the role of the anti lock braking system in a vehicle? What is an anti lock braking system f

ABS can really save lives at critical moments.

Speaking of ABS, friends who know a little bit about cars have heard this word, ABS is the brake anti-lock braking system.

What is brake locking? It is that the vehicle brakes too thoroughly in the movement and directly clamps the four wheels, but because of the inertia, it will still push the car forward for a certain distance, but this distance The car is in a state of loss of control, and the driver can not control the direction of the car, which will lead to more serious traffic accidents, and all this will happen in just 1-2 seconds, and the driver can not react at all.

In order to deal with the traditional brake locking, the automotive industry has derived a set of ABS brake anti-lock braking system, which is composed of sensors, ABS computers, and ABS master cylinders.

Compared with traditional brakes, the ABS braking system will judge the strength of the brake through sensors and computers, so as to achieve the maximum braking force without locking out of control, which is its main role.

The driver does not need to react, and can step on the brakes normally, but the car is still controllable when braking, which greatly increases the safety factor.

Now many cars and motorcycles at home and abroad are equipped with this type of braking system, of course, the car with this system will be a little more expensive than the same level without ABS.

However, Lao Mo thinks that this money is still worth spent, and it can really save lives at critical moments.

The anti-lock braking system automatically controls the braking force of the brake when the car brakes, so that the wheels are not locked and are in a state of rolling and slipping (the slip rate is about 20%), so as to ensure that the adhesion between the wheels and the ground is at the maximum.

What exactly is the ABS anti-lock braking system used for?

During normal driving, the tires form a "rolling friction" with the ground (the direction is controllable), and when the vehicle without ABS brakes urgently, the tires will be locked. The "rolling friction" between the tire and the ground will turn into "sliding friction", and the "sliding friction" is uncontrollable, and the car will lose control at this time, and if the speed is too fast, it will cause serious consequences.

As the name suggests, ABS (anti-lock braking system) is to control the tires between "rolling" and "sliding", which seems to be slippery but not slippery, and keeps the tires from being locked to maintain the vehicle from losing control. ABS has basically become the standard configuration of current cars, and any car is equipped with ABS. When we brake suddenly, the drive wheels have a "click" bump sound, which proves that ABS is involved at this time.

The main role of ABS is reflected in the fact that "when the brake is pressed, it ensures the lateral stability of the car, it is easier to control the direction for the car that is about to lose control, and the intervention is automatic to save the trouble of opening."

The principle of ABS: when the vehicle performs emergency braking, ABS will automatically adjust the oil pressure of the "brake oil pipe" according to the speed of the wheels before braking, and adopt the cycle mode of "braking-braking-braking", and finally "imprison" the driving wheels between locking and rolling at about 10 times per second, so as to ensure that the vehicle can obtain the maximum braking force, and then ensure that the vehicle will not lose control.

The car anti-lock braking system is commonly known as the ABS anti-lock braking system. In layman's terms, the ABS anti-lock braking system is to ensure that the car still has the ability to steer during emergency braking, and will not cause the front wheels of the vehicle to lock up and fail to steer and cause rollover.

ABS is the English abbreviation of anti-lock braking system, and the full name in English is Anti LockbrakingSystem, or AntiskidbrakingSystem. The system automatically adjusts the braking force of the wheels during braking, preventing the wheels from locking up for optimal braking results. ABS controls the pressure of the brake line acting on the wheel brake cylinder, so that the wheels of the car will not lock during emergency braking, so that the car can still maintain good directional stability during emergency braking.

The anti-lock braking system is to automatically control the braking force of the brake when the car is braking, so that the wheels are not locked and are in a state of rolling and slipping (the slip rate is about 20%), so as to ensure that the adhesion between the wheels and the ground is at the maximum. The anti-lock braking system of automobiles, abbreviated as ABS in English, is used to prevent the tires from locking up when the car brakes suddenly, thereby affecting the stability of the car.

The anti-lock braking system can effectively control the wheels to keep in a rotating state, improve the stability of the car during braking and the braking performance of the car under poor road conditions. ABS continuously detects the speed of each wheel through the speed sensor installed on each wheel or transmission shaft, calculates the wheel slip rate at that time by the computer, and compares it with the ideal slip rate, makes a decision to increase or decrease the brake pressure, and orders the actuator to adjust the brake pressure in time to keep the wheel in an ideal braking state.

The main function of ABS is to improve the braking performance of the whole vehicle, improve driving safety, prevent the wheels from locking (i.e., stop rolling) during braking, so as to ensure that the driver can also control the direction when braking, and prevent the rear axle from slipping. Its working principle is: during emergency braking, relying on the wheel speed sensor with high sensitivity installed on each wheel, once it is found that a wheel is locked, the computer immediately controls the pressure regulator to relieve the brake cylinder of the wheel, so that the wheel resumes rotation, so as to prevent the wheel from locking.

The working process of ABS is actually the cyclic working process of "locking-loosening-locking-release", so that the vehicle is always in a critical lock-up gap rolling state, effectively overcoming the vehicle deviation phenomenon caused by wheel locking during emergency braking, and preventing the occurrence of loss of control of the body.

Summary. Pro, like Changan Automobile's anti-lock braking system, the first is the anti-lock braking system independently developed by Changan Automobile. For example, in the frequency of point brakes, the frequency of Changan Automobile is higher, and after stepping on the brake, it can adjust the pressure more quickly, and the number of adjustments is relatively more.

In addition, in the control process, the pressure sensor installed in the braking system can sense the braking force, so as to intervene in the anti-lock braking work of the braking system.

1. ABS anti-lock braking system is a kind of automobile safety control system with the advantages of anti-skid and anti-locking;

2. It is based on the improvement of traditional braking device technology, which can be divided into two types: mechanical type and electronic type;

3. It has the braking function of the commonly used braking system, which can also prevent the wheel from locking, so that the car can still turn under braking, ensure the stability of the braking direction of the car, and prevent side slip and deviation.

The anti-lock braking system of the car is called ABS, which automatically controls the power of the brake when the car is braking, so that the source wheel of the car is not locked and is in a state of slipping and rolling, so as to ensure that the adhesion between the wheel and the ground is at the maximum.

The automobile brake anti-lock braking system Zaozhen is the so-called ABS system, which has a very large comic effect. In particular, rain and snow weather can prevent the car from rolling over and sliding during emergency braking, which is very important for safety.

Maintain directional stability when braking the car.

Automotive Anti-lock Braking System Definition:

ABS anti-lock braking system is an automobile safety control system with the advantages of anti-skid and anti-lock.

1. Advantages of automobile anti-lock braking system:

When the wheel is about to reach the next locking point, the pressure of the brake fluid causes the airbag to act repeatedly, so that it can act 60 120 times in one second, which is equivalent to non-stop braking and relaxation, that is, similar to the mechanical "point brake".

Therefore, the ABS anti-lock braking system can avoid the loss of direction and wheel slippage during emergency braking, so that the wheels are not locked when braking, and the tires are not allowed to rub against the ground at a point, so as to increase the friction and increase the braking efficiency, so that the braking efficiency can reach more than 90%, and at the same time, it can also reduce brake consumption, and the service life of the brake wheel drum, disc and tire is twice as long as the extension cavity.

The anti-skid performance of vehicles equipped with ABS on dry asphalt roads, rainy days, snow days and other road surfaces reaches %-20% respectively.

2. Limitations of automobile anti-lock braking system:

The ABS system does not provide the shortest braking distance. One is on smooth trunk roads, where the brakes are applied directly by an experienced driver. Another scenario is braking on loose gravel roads, loose dirt roads, or roads with deep snow.

In addition, usually on dry roads, the most new ABS systems can control the slip rate in the range of 5%-20%, but not all ABS brakes at the same rate or to the same extent.
