What is the ABS system
ABS is an abbreviation, which is transcribed in the various languages of the world. But also Germans, Englishmen, Russians believe the ABS system, which does not automatically lock the wheels when braking. Thanks to the adjustable force exerted by brakes. And the main objective that confronts the ABS system, is to provide a motorist the ability to control the vehicle by maintaining stability and providing the most effective deceleration on the market.
It is clear that under braking, Yes the sharper, the car whose wheels are locked, will turn. Before this happened, and was invented ABS system.

The idea of creating ABS
Even before the invasion of Hitler’s Europe an idea to create a similar system was born in the minds of leading engineers of the time. And planned to apply such a system not just anywhere, but in the aviation. But the materials and technologies used in that period of time, unfortunately, was never given the opportunity to do so.
In 1964, engineers at Mercedes took the case, roll up their sleeves. Helped them specialists Bosch and Teldix. First and foremost were collected all patents, and reports in recent years, where somehow mentioned about the ABS system.
Studies initiated so successfully began to bring results. Engineers have determined the General outline of a new system that could become a breakthrough in the technology of the future. Calculation of the speed of rotation of the wheel assigned to the sensors which then were set only on the front axle. These same sensor measurements sent to the control unit, and if necessary given the amendments to Yiwu to set the pressure in the brake system, or rather in any part of it. But all went smoothly only on paper. But as you know, all the ingenious discoveries of mankind were made on paper first and then transferred to practical field activities.
Initially, the ABS system in real situations worked correctly. Reacted to the change of coupling of wheels with delays and, in short, was unreliable.
The success of the first engineers of the ABS system was reached in 1967, when they replaced the sensors on a mechanical base, equipped with wheels, contactless options. The principle of action in this case was used like electromagnetic induction. And the benefits were clearly evident: the ABS system falsely did not work, was resistant to mechanical stress and for a long time did not wear out.
Already in the mid-twentieth century the company Mercedes has presented on display to the public the first ABS system with electronic control, designed for buses, trucks and passenger cars. New sensors transmitted to the control unit signals and the operated hydraulics, that is, the module is placed between the calipers and brake cylinder.
Today even the most modern ABS system repeats the principle of the first model. Everything happens due to the work of sensors that monitor the rotational speed of the wheels and give information about it BOO. And he compares those values and sends appropriate commands to the electromagnetic component, in particular valve of the hydraulic module.
Mercedes introduced the first electronic ABS
The valves are designed to regulate the pressure in the brake system. And this is done kind — a pair on each circuit. When there is a sharp and unexpected braking, components of the ABS system with a frequency of several tens times per second begin to move and there is a deceleration of the vehicle. When the valves drivers often hear them chirping, signifying that the wheels went through the process of locking/unlocking. And pressure in several loops or one of them instantly rises and then immediately drops. As for pads, they respectively compress and release the disk, ensuring reliable braking. Works like ABS.
It is clear that the most important thing while driving is early braking. And to keep the car in such conditions is very difficult. But the ABS system is perfect with this helps to cope.
In fact, the ABS system is a rather complex anti-lock braking system, representing the electro-mechanical circuit, not allowing the car to block the wheels when braking. And especially need the ABS system when driving on roads where the wheels of the vehicle are not well cling to the road surface. In other words, when driving on gravel, snow, even snow or ice. The ideal security system on the roads of Russia, where more than half of the months of winter.
Any difficulties driving instruction in a car with ABS does not. You can go at high speed and not be afraid of sudden braking, because the braking distance is significantly reduced.
If you want to know, have you installed your car with such a system, simply turn the ignition key. And then it will show on the dashboard. Even the ABS system can be determined by other parameters, including the overly sensitive brake pedal.

What it is
Conventional ABS system consists of three components. Important is the ABS unit located in front of and interacting with the brake system in a special way. Thanks to a special metal tube type and connection block with the brakes.
In addition, the computer is part of a system. It processes data obtained from sensors, and sends appropriate signals to the main unit.
Finally, the speed sensors, without which none of the modern ABS systems work.

The main advantage of the ABS system
In practice through numerous tests it was proved that the ABS system allows to achieve a shorter braking distance. The driver of the vehicle is increased several-fold the ability to control the vehicle, keeping strict control. In addition, the system gives the opportunity to carry out maneuvers under sudden braking. Combining the above two factors, the vehicle having a system of ABS, gets a huge advantage over conventional vehicles.
Some drivers with more seniority are able to brake properly without ABS. They control the time of collapse of the wheels independently, as do motorcyclists. Thus, the force is weakened when you stop at the edge of the lock and the braking is not sharp, and intermittent. But such an effect is obtained at considerable cost of energy, comparable to single-channel ABS. And there is, as we know, multi-channel ABS, designed to control braking forces on each wheel individually. This form not only allows ABS brake efficiently, but also to stabilize the behavior of the vehicle in difficult conditions. For example, when driving on snowy icy roads when the clutch wheels and the road surface is uneven.
In any case for a novice driver even a single channel ABS will be a great help. He will learn to brake safely without fear of the consequences. He will just need to apply maximum effort to the brake pedal or the handle, while maintaining the maneuver.
The work of the ABS system in some cases, as mentioned above, leads to longer braking distance. This is very important, for example, if you drive on winter roads on summer tyres. In addition, on loose surfaces such as deep snow or gravel, a locked braking wheel burrow deep into the surface, and it gives additional slow.
Interestingly, on some cars put the ABS system, which automatically switches itself off. In fact, it is very convenient and efficient. And even put on some models of ABS special algorithm braking, allowing to achieve effective deceleration without loss of control. The same happens at full lock. With regard to the type of surface, it can be installed manually by the driver by means of the connection of special sensors.
Technology Break Assist
This technology, used for ABS systems, appeared in 1994 on the popular then and today the German car Audi. Soon, having learned all the advantages of the technology for the Audi pulled and other companies: Volkswagen, Mercedes, infiniti, etc.
How does ABS on cars, technology Break assist helps the driver brake efficiently. According to statistics the majority of drivers in emergency situations on the brake fully depress or release the brake pedal. And the braking distance because of this it turns significantly more than could be. Technology Break assist and is designed to automate this process.

And finally. The ABS system is a smart robot that does practically everything associated with the brake system of the car instead of a person. And does it in some cases even better than people.
