1. ABS anti lock braking system, the brake is fully applied. Lock up means that the brake caliper is clamped tightly. Anti lock braking system is to release a little brake caliper at the moment of locking. The purpose is to prevent the wheels from being locked and unable to turn (after locking, the wheels can turn, but the car will continue to slide forward e to centrifugal force, and anti lock is to prevent the car from not turning e to centrifugal force). Today's anti lock braking system of passenger cars has been locked and released more than 16 times in a second (heavy trucks and buses don't use oil brakes, so the anti lock system is a little different. I won't study it here).
2. It's the ABS system. When you step on the car's brake to the end, the wheels lock up. When the wheels "drag" on the ground, the direction is out of control
ABS system is used to prevent this phenomenon. When the wheel lock is detected, it will automatically release the brake and let the wheel roll. Then it brakes again and releases automatically. In this way, "one release and one brake" imitates the action of quick braking.

3. BS is the abbreviation of antilock braking system, which means anti lock braking system. It works with the traditional braking system, and is a safe and effective brake assist system. Its main function is to prevent the wheels from locking (i.e. stop rolling) ring braking, so as to ensure that the driver can control the direction when braking, and rece the braking distance in some cases, such as on wet road. For vehicles not equipped with ABS, the driver can manually prevent the wheel from locking by braking the brake pedal, but it is too high for the driver's operation skills, which is difficult for ordinary people to do. The ABS system automatically controls the oil pressure of the braking system through the computer. The driver only needs to step on the brake pedal, and the system can automatically and quickly adjust the braking force, so as to achieve the maximum braking efficiency and prevent the wheels from locking. When the vehicle is braking on the wet road, or in the emergency braking, the wheels are easy to lock, so that the driver will lose the ability to control the steering, and the vehicle will have a serious tail flick or even out of control. The rear wheel ABS can prevent the lock of the rear wheel and ensure the straight driving of the vehicle
4. ABS is the abbreviation of antilock braking system in English, which is translated into "anti lock braking system" in Chinese. It can be divided into mechanical type and electronic type. It is an automobile safety control system with the advantages of anti-skid and anti lock. ABS is an improved technology based on the conventional braking device. It works with the traditional braking system. It is a safe and effective auxiliary braking system
principle: it uses a rubber air bag in the valve body to give the brake oil pressure to fill the ABS valve body when the brake is pressed. At this time, the air bag uses the air barrier in the middle to return the pressure and make the wheel avoid the lock point. When the first wheel is about to reach the next lock point, the pressure of the brake oil causes the air bag to act repeatedly. In this way, the air bag can act 60 ~ 120 times in one second, which is equivalent to constantly braking and relaxing, which is similar to mechanical "point braking". Therefore, ABS anti lock system can avoid out of control direction and wheel sideslip ring emergency braking, so that the wheel will not be locked when braking, and the tire will not rub with the ground at one point, so as to increase the friction force and make the braking efficiency reach more than 90%. At the same time, it can rece brake consumption and extend the service life of brake drum, disc and tire twice. The anti-skid performance of ABS vehicles on dry asphalt road, rainy day and snowy day reaches 80% - 90%, 30% - 10% and 15% - 20% respectively
the world's first anti lock brake system, ABS (anti lock brake system), came out in 1950, was first used in aircraft in the aviation field, and began to study its application in automobiles in 1968. In the 1970s, the disc brakes were used in the front or front and rear wheels of new cars made in seven European and American countries, which promoted the application of ABS in cars. After 1980, computer-controlled ABS graally expanded rapidly in Europe, the United States, Asia and Japan. So far, some medium and high-end luxury cars, such as Mercedes Benz, BMW, Yadi, Porsche, Opel Series in West Germany, Rolls Royce, Jetta, Luhua, Bentley Series in Britain, Ferrari, aikuai, Xiandai, Kuai Series in Italy, boerscher Series in France, tx3, 30x, red comet of Ford in the United States, and emperor, New York luxury, Baron, etc. of Chrysler Dodge, Shunfeng series, Japan's civic, Lexus, luxury Honda, Benyue, Junlang, shunv 300Z series, all adopt advanced ABS. Up to 1993, the United States has installed ABS on cars up to 46%. Nowadays, nearly 75% of cars proced in the world are equipped with ABS
nowadays, many companies around the world have proced ABS, such as Bendix, Bendix, Bosch, Morgan Davis, Hayes Kelsey, sumitom, Honda, Japan infinity, etc., among which there are integral and non integral. It is expected that with the rapid development of cars, there will be more manufacturers

5. Anti lock brake system (ABS) for short. The function is to automatically control the braking force of the brake when the car is braking, so that the wheel will not be locked and will be in the state of rolling while sliding (the slip rate is about 20%), so as to ensure the maximum adhesion between the wheel and the ground
anti lock braking system can improve the safety factor of vehicle emergency braking when driving. In other words, cars without ABS are prone to tire lock when they take emergency braking in case of emergency, that is, the steering wheel can't rotate, so the risk factor will increase and it is easy to cause serious consequences. When the wheel is about to reach the next lock point, the pressure of the brake oil causes the air bag to act repeatedly. In this way, the air bag can act 60 ~ 120 times in a second, which is equivalent to constantly braking and relaxing, which is similar to mechanical "point braking". Therefore, ABS anti lock system can avoid out of control direction and wheel sideslip ring emergency braking, so that the wheel will not be locked when braking, and the tire will not rub with the ground at one point, so as to increase the friction and make the braking efficiency reach more than 90%. At the same time, it can also rece braking consumption and extend the service life of brake drum, disc and tire twice. The antiskid performance of ABS vehicles on dry asphalt road, rainy day and snowy day reaches 80% - 90%, 10% - 30% and 15% - 20% respectively.

2. The ABS lamp always on has no effect on the normal braking of the vehicle and will not lead to brake failure. But if there is an emergency that requires a sudden brake, the ABS system will not work at this time
3. The common problem of ABS is that the sensing part of ABS wheel speed sensor is covered by soil and mud, which affects the corresponding speed signal sensed by the sensor, so that ABS computer can't judge the speed, and can't take back the corresponding action command to control the braking. Just clear the dirt on the sensor and adjust the clearance between the wheel speed sensor and the signal ring gear to return to normal
4. The ABS light alarm indicates that there is a fault in the ABS system.
the ABS light alarm has the following conditions:
(1) the fault of the wheel speed sensor. Through the computer diagnostic instrument, we can know which wheel speed sensor has problems
(2) there are two kinds of wheel speed sensor faults. One is the ABS alarm caused by the broken wheel speed sensor. One is that the ABS sensor is dirty, which causes the ABS sensor can not detect the wheel speed and causes the ABS fault light alarm. If the wheel speed sensor is dirty, just clean the sensor
(3) wheel speed sensor circuit fault. If the wheel speed sensor circuit is damaged, it will also cause ABS failure. Only the wheel speed sensor harness can be replaced for this kind of fault
to sum up,
the ABS alarm light shows the working state of the vehicle ABS. If the indicator light is not on ring the vehicle self-test or is always on after starting, it indicates that there is a fault in the system. ABS is an important safety guarantee of the braking system, and it needs to be repaired in time when there is a problem.

8. The working principle of ABS is divided into mechanical and electronic. Because the mechanical type can't compare with the electronic type in terms of accuracy or actual effect, most of the
ABS on cars are electronic. It consists of hydraulic braking system, wheel speed sensor, electronic controller and electromagnetic regulator. The sensing mechanism of
ABS
is composed of wheel speed sensor and "gear ring". In the wheel speed sensor, there is an electromagnetic coil which can generate magnetic lines of force, which is installed on a fixed part near the wheel. The ring gear is installed on the wheel rim. The wheel rotation drives the ring gear to rotate. The ring gear cuts the magnetic lines of force, which makes the electromagnetic coil in the sensor ince alternating current. Its pulse rate is proportional to the wheel speed and is transmitted to the electronic controller. The electronic controller is a micro electronic computer. According to the current pulse signal of each wheel speed sensor, it can measure the movement speed, acceleration or deceleration, slip rate and other values of each wheel. When these values exceed the normal range, it will send commands to the electromagnetic regulator. The plunger in the electromagnetic regulator will move up and down according to the command to adjust the oil input to the wheel brake cylinder, which acts as a valve
the working principle of ABS
is simple, that is, the wheel speed sensor monitors the wheel speed, and the monitoring signals are collected into the electronic controller for analysis. Once it is detected that the wheel is about to lock, the electronic controller will send a command to the electromagnetic regulator, which will control the oil pressure distribution valve to adjust the brake cylinder of each wheel, and control the brake friction plate in the form of "one release and one retraction" to release the lock phenomenon of the wheel. Braking with spot release can not only rece the wheel speed sharply, but also maintain the adhesion between the tire and the ground.
