What is ABS systemWhat is ABS system?

The ABS system is a braking anti-lock braking system. It is mainly to prevent the wheels of the car from slipping and causing rollover, and at the same time shorten the braking distance to reduce brake consumption, and prolong the service life of brake discs and plates and tires twice.

It consists of an electronic control unit, several wheel speed sensors and a valve assembly with an integrated solenoid valve. The electronic control unit uses pulse changes from the wheel speed sensor to monitor the operating condition of the wheels. When a certain wheel may be in a locked state, the electronic control unit will send a command to the solenoid valve, so that it can control the brake and adjust the speed through a quick switch.

Introduction

In general, this type of fast-opening valve can be moved up to 12 times per second. Some premium models of ABS can have a four-circuit system, i.e. four-circuit ABS"。There are two main types of such high-tech products: electronic and mechanical.

The electronic safety factor is higher, and the first is also high, which was originally only configured on large luxury cars, and with the development of the times, small and medium-sized ordinary cars have also begun to be configured; The mechanical safety factor is low, and it is generally only used in commercial vehicles.

In China, Dongfeng Motor Company has organized the development of ABS since 1992, and passed the technical inspection and monitoring appraisal in December 1995. The Chean brand ABS developed by Sichuan Chean Technology Development Company has been used in some mini cars. ABS has become the mainstream of automotive technology in the 20th century, and the era of all cars equipped with ABS is not far off.

Antilock brake system (ABS) is abbreviated as ABS. The function 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 development of the ABS system dates back to the early 20th century. In the late 70s of the 20th century, the rapid development of digital electronic technology and large-scale integrated circuits laid a technical foundation for the practical development of ABS system, and many companies have developed various forms of ABS system. Since the mid-80s of the 20th century, the ABS system has developed in the direction of high cost performance.

Some companies have simplified the structure and optimized the system of ABS, and launched an economical ABS device; Some companies have introduced rear-wheel ABS or four-wheel ABS systems for light trucks and passenger and cargo vehicles.

These efforts have created the conditions for the rapid popularization of ABS. The ABS system is considered to be the most important technical achievement in terms of safety since the introduction of seat belts in automobiles.

"abs" translates to "anti-lock braking system" in ChineseIt is an automotive safety control system with the advantages of anti-slip and anti-lock. ABS is an improved technology based on conventional braking devices, which can be divided into mechanical and electronic types.

A large number of anti-lock braking systems are installed on modern automobiles, ABS has the braking function of the ordinary braking system, and can prevent the wheels from locking, so that the car can still steer in the braking state, ensure the stability of the braking direction of the car, prevent the occurrence of side slip and deviation, is the most advanced braking device on the car at present, the best braking effect.

ABS is the abbreviation of English Anti-lock brake system, as the name suggests, it plays a role in preventing brake locking. When the car is moving forward, if it encounters emergency braking, once the steering wheel is locked, then the car will move along the trajectory before the lock, no matter how you dial the steering wheel. This is very dangerous, so ABS was created to solve this problem.

With ABS, it is not easy to lock in the emergency braking, which greatly improves the handling and safety in the emergency braking state. The earliest ABS was transplanted from the early airplanes, because the plane was relatively slow in the sky when landing, but the speed on the ground was still too fast, and it was easy to lock the steering wheel when braking when landing, and once it was locked, the plane was easy to rush out of the runway. Therefore, from being studied and applied to specific objects, airplanes and automobiles are similar.

ABS is the abbreviation of anti-lock braking system, and its function is to prevent the wheels from locking up when braking in an emergency or skidding the road to brake the suspect car.

The ABS system has a great effect on emergency braking and lock-up braking. This one is also relatively safe.

The ABS system is the anti-lock braking system of the car, which prevents the car from braking and locking on its own.

What is the role of the ABS system?

The anti-lock braking system can improve the safety factor of the vehicle's emergency braking when driving. In other words, if there is no ABS car, the car is prone to tire locking when taking emergency braking in an emergency, that is, the steering wheel cannot be rotated, so the risk factor will increase, and it is easy to cause serious consequences.

Precautions for using ABS.

Clause. First, it is necessary to maintain sufficient braking distance. When driving on good roads, make sure to have at least 3 seconds of braking time away from the vehicle in front of you, and leave more time for braking when driving on bad roads.

Clause. Second, because the ABS emergency braking wheel is not locked, the front wheel still has a guiding role, the driver can brake while playing the direction for emergency avoidance.

Clause. 3. Don't press the brake pedal repeatedly. When driving an ABS car, repeatedly pressing the brake pedal will cause the ABS to be switched on and off, resulting in a decrease in braking efficiency and an increase in braking distance.

The ABS system itself has its limitations.

It still can't get rid of certain physical laws. In both cases, 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 latest 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. It is equivalent to using the most reasonable braking method to help us brake the car, but ABS (anti-lock braking system) itself cannot improve the braking limit of our own car, or the physical limit of the friction of the tire itself, that is, ABS (anti-lock braking system) is a safety system that tries to shorten your braking distance.
