What is the function of the anti lock braking system

It is the ABS system, as soon as the car brakes to the end, the wheels will be locked, the wheels will be "dragged away" on the ground, and the direction will be out of control.

The ABS system is designed to prevent this. When the wheel locks are detected, the brakes are automatically released to allow the wheels to roll. Then automatically brake again, and then automatically release again. In this way, "one release and one brake" imitates the action of quick brake.

For most cars nowadays, it has something called the ABS anti-lock braking system. So what exactly is this thing for? How powerful is it that it has become a system that most cars have to install now?

After reading it, many riders sighed: No wonder it has become the standard configuration of the car!

ABS 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 (slip rate is about 20%), so as to ensure that the adhesion between the wheels and the ground is at the maximum.

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.

On a car that is not equipped with ABS, the car can easily lose directional stability if braking on snow; At the same time, if the driver wants to stop, he must use a hydraulic regulator (also known as an actuator). Conversely, if the car is equipped with ABS, the ABS can automatically issue control commands to the hydraulic regulator, so that the brakes can be controlled more quickly, accurately and effectively.

How it works. ABS only after the speed of the car exceeds a certain amount (such as 5km h or 8km h), the anti-lock braking pressure adjustment will be carried out on the wheels that tend to lock during braking.

When the speed of the car is reduced to a certain by braking, ABS will automatically abort the anti-lock braking pressure adjustment, after which, the braking process of the car equipped with ABS will be the same as the braking process of the conventional braking system, and the wheels are locked to the car brake lock.

This is because when the speed of the car is very low, the impact of the wheels being locked by the brakes on the braking performance of the car is already very small, and the wheels should be locked up in order for the car to brake and stop as soon as possible.

It is the ABS system, as soon as the car brakes to the end, the wheels will be locked, the wheels will be "dragged away" on the ground, and the direction will be out of control.

The ABS system is designed to prevent this. When the wheel locks are detected, the brakes are automatically released to allow the wheels to roll. Then automatically brake again, and then automatically release again. In this way, "one release and one brake" imitates the action of quick brake.

The anti-lock braking system is to prevent the wheel from slipping on the slippery road surface and the wheel locking is prone to skidding, and the anti-lock braking system will intervene in this situation so that the wheels will not lock in this situation and cause an accident.

Hello, ABS brake anti-lock braking system is to automatically simulate stepping on the brakes as soon as they loosen and tighten, which can prevent brake locking.

This system allows you to keep your steering ability open when you brake hard without the wheels locking up.

To put it bluntly, it is to prevent the brake system from locking.

It not only has the braking function of the ordinary braking system, but also can prevent the wheel 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, and is the most advanced braking device with the best braking effect on the car at present.

1. During braking, the ABS control unit continuously obtains the speed signal of the wheel from the wheel speed sensor and processes it to determine whether the wheel is about to be locked;

2. The characteristic of ABS brake braking is that when the wheel tends to lock the critical point, the pressure of the brake cylinder does not increase with the increase of the pressure of the brake main cylinder, and the pressure changes near the critical point of locking;

3. If the wheel does not enter the locking state, the brake pressure adjustment device does not participate in the work, and the braking force will continue to increase; If it is judged that a certain wheel has a tendency to lock, the ECU sends a command to the brake pressure regulator to close the channel between the brake cylinder and the brake wheel cylinder, so that the pressure of the brake wheel does not increase.

1. The anti-lock braking system is an active safety system on the car, which is what we often call it"abs\"The braking system, which is improved on the basis of the conventional braking device, is mainly used to prevent the wheel from locking during emergency braking;

2. If the two front wheels are locked at the same time, the car basically drives in a straight line, but loses the ability to control the steering lead and rough Huai skin, and cannot avoid obstacles; If the rear wheels are locked at the same time, the car will be in danger of skidding and tail flicking under the action of very little lateral force. Therefore, now cars are basically installed with ABS to prevent this danger from happening;

3. The working principle of ABS system: mainly relying on the high-sensitivity wheel speed sensor installed on each wheel and the speed sensor on the transmission, according to the degree of wheel slippage, the computer is automatically controlled by a set of hydraulic control system, so that the car is always in a state of locking and rolling when braking suddenly, that is, the cyclic working process of locking and loosening. The pressure increase and decrease in the brake can be adjusted very quickly, which can reach 10 20 times per second, and the high-gear car can reach 60 times (the higher the frequency of adjustment, the better the braking effect);

4. So that the wheels can be kept rolling all the time, without locking, ensuring that the car still has good steering ability during emergency braking, and preventing sideslip or tail flicking.

The role of the anti-lock braking system. The anti-lock braking system is a common active safety system in automobiles. That is, Changchun's ABS automatic system. He was an improvement on the basics of conventional braking devices, and the key role was to avoid wheel locking during emergency braking.

If the two fists are killed at the same time, the car will generally drive in a straight line, but it will lose the ability to adjust the steering and cannot avoid obstacles. Suppose the rear wheels lock at the same time. With very little lateral force, the car will be able to slip and flick its tail.

Therefore, ABS is basically installed in the current car class. so as not to cause such a danger to happen.

The working principle of the ABS system depends on the high-sensitivity wheel speed sensor installed on each wheel and the vehicle speed sensor on the gearbox. According to the degree of wheel slippage, the computer automatically adjusts it through a set of hydraulic adjustment system. So that the car is always in a state of sudden death and rolling when braking suddenly.

Quarterly report: Dead and loose, pick up and die and loosen the circular workflow. The pressure increase and decrease in the automaton is extremely fast. Yes, 10 to 20 times per second.

High-end cars can be hit 60 times. (The higher the frequency of the adjustment, the better the effect of braking.) ）

Then the wheels will keep rolling and not locked. It ensures that the car still has good steering and ability during emergency braking, and avoids side skidd or tail flicking.

ABS stands for: Brake Anti-lock Braking System. Its function is to automatically control the braking force of the braking system when the car is braking, so that the wheels are not locked, so that the wheels are in a state of rolling and slipping, so as to ensure that the adhesion between the wheels and the ground is at the maximum.

It is possible to shorten the braking distance of the brakes. ABS is usually composed of wheel speed sensor, brake pressure Plum Adjustment device, ABS electronic control unit and ABS warning light. When the system fails, the ABS fault light of the dashboard will be lit to remind the driver to drive carefully and check and repair as soon as possible.

Let's take a look at what are the common reasons for ABS fault lights to light up and how to eliminate them.

1. ABS wheel speed sensor is damaged or dirty. The sensor needs to be cleaned or replaced.

2. The ABS signal wheel is damaged or dirty. Bearings need to be cleaned or replaced.

3. The ABS line is broken due to external force or the sensor plug is connected to the water. Repair of the wires as well as plug connections is required.

4. The fault lamp is lit due to the damage of the ABS control unit. The control unit needs to be replaced.

5. The power supply voltage is unstable, and ABS cannot work normally, resulting in the fault light being lit. The vehicle's power supply system needs to be checked.

6. The four-wheel alignment is incorrect, and the speed and direction angle of the four wheels of the vehicle are different, which causes the ABS light to be lit. Wheel alignment is required, and damaged parts need to be replaced if necessary.

If the ABS lamp is lit, it is recommended to go to a professional maintenance company for maintenance as soon as possible.

Anti-lock braking system refers to the control system that prevents wheel brake locking and slipping during braking, abbreviated as ABS. The electronically controlled anti-lock braking system is an active safety device added on the basis of the ordinary braking system of the auto socks, which is mainly composed of wheel speed sensor, ABS electronic control unit (i.e. ABS ECU), ABS pressure regulator and warning light, brake master cylinder, brake pedal wheel speed sensor. Wheel speed sensor adjusterWheel speed sensor wheel speed sensor ABS, wheel speed sensor is used to detect wheel speed, and reflect the movement of each wheel to ABS ECU.

ABS ECU is the command center of ABS, which is used to receive the signal sent by the wheel speed sensor, calculate the rotational speed, acceleration, deceleration and slip rate of the wheel, analyze and process, and then send a control signal to the ABS pressure regulator to make the brake pressure regulator work as required. ABS ECU also has a fault self-diagnosis and disconnection function, when ABS fails, it can disconnect the relay, solenoid valve and pump motor circuit and shut down ABS, store fault information, and light ABS warning light. ABS pressure regulator is the actuator of ABS, used to adjust the pressure of the braking system, it adjusts the oil pressure acting on each brake wheel cylinder by decompressing, maintaining pressure and increasing pressure according to the control instructions transmitted by ABS ECU, so as to control the speed of the wheel.

ABS warning light is a yellow warning light, which is used to warn ABS failure, so that the driver can intuitively judge the condition of ABS.

The braking performance of the car is an important guarantee for the safe driving of the car, and the application of the anti-lock braking system plays an important role in ensuring the driving safety of the majority of car owners. What is the principle of the anti-lock braking system?

The Anti-lock Braking System (ABS) automatically adjusts the braking force of the wheels when braking, preventing the wheels from locking up and achieving the best braking effect. When the wheel is close to locking, the braking pressure of the respective wheel is released and remains constant during the reacceleration required or measured by the wheel, and gradually increases after reacceleration. The anti-lock braking system guarantees the maneuverability and stability of the vehicle itself when braking within the physical limits.

When accelerating, it can also prevent the tires from slipping, improving acceleration performance and running stability.

The anti-lock braking system 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. In a car without an anti-lock braking system, it is easy for the car to lose directional stability when braking in the snow. If our car is equipped with an anti-lock braking system, the anti-lock braking system can automatically send control commands to the hydraulic adjuster, which can control the brakes faster, more accurately and more efficiently.

However, it is important to note that the anti-lock braking system does not provide the shortest braking distance in the following two situations. 1.On flat slammed main roads, experienced drivers will brake directly.

2.Brake on loose gravel roads, loose soil surfaces, or roads with deep snow.

What is the principle of the anti-lock braking sock preparation system? The relevant content is explained below. The braking performance of the car is an important guarantee for the safe driving of the car, and the application of the anti-lock braking system plays a great role in ensuring the driving safety of the majority of car owners.

What is the principle of anti-lock braking system?

The Anti-lock Braking System (ABS) automatically adjusts the braking force of the wheels during braking to prevent the wheels from locking up for optimal braking results. In the event that the wheel is close to locking, the braking pressure of the corresponding wheel is released and remains constant during the required or measured wheel reacceleration, gradually increasing the braking pressure after the reacceleration. The anti-lock braking system ensures the handling and stability of the vehicle itself during braking within the physical limit of performance.

When accelerating, it can also prevent pure slippage of the tire, which improves acceleration performance and operation stability.

The anti-lock braking system 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. In a car that is not equipped with an anti-lock braking system, braking on snow can easily cause the car to lose directional stability. If our car is equipped with an anti-lock braking system, then the anti-lock braking system can automatically send control commands to the hydraulic regulator, which can control the braking more quickly, accurately and effectively.

However, we should note that in the following two cases, the anti-lock braking system does not provide the shortest braking distance. 1. On smooth trunk roads, braking is carried out directly by experienced drivers. 2. Braking on loose gravel roads, loose dirt roads, or roads with deep snow.
