Principle Analysis of ABS Brake Assist System

In recent years, there have been many simple and even ridiculous traffic accidents that frequently appear in our vision, but after we understand the content, we are quickly removed from the brain memory, and how many people analyze it. What is the reason? In fact, the information of traffic accidents is not just for the detailed analysis and statistics of professionals. Everyone in the society is actually a participant in traffic behavior. It is absolutely very important to think deeply about the causes of these accidents. necessary.

With the application of a large number of high-tech products to the automotive industry, the relevant indicators of the automobile have indeed become more advanced, and the key technical indicators such as handling and safety have been greatly improved. But everyone must be aware of this: so far, a large number of cars still need people to control! The driver's ability is always the first element of vehicle control. But there are a lot of common-sense problems at the moment, but it is not everyone knows, such as braking.

Braking is a very important skill in vehicle control technology. In recent years, due to the popularity of a large number of electronic control components, much of the work in braking technology has been taken over by computers and even taken over. Even so, there are a lot of new common sense about brakes that need to be remembered by all drivers, because if the powerful electronic control device does not have the opportunity to fully play or even work, how high-tech one car will become a killing machine. .

At present, most of the commercial cars are equipped with ABS system, but how much do you know about ABS? It is not the principle of this device, nor the structure of this device, just the use of this device. There are many misunderstandings about this point. These seemingly simple differences in understanding may lead to a terrible result at the most critical time. Let's talk about where these misunderstandings are, and how terrible it is.

First of all, how to use ABS? Simply put a word: how fast you can step on the brake pedal, you can use more force, until the car stops, do not let go of your feet. This brake method was an absolute paradox, a fatal wrong method, twenty years ago. That is because there is no ABS at the time. Such a brake will cause the wheel that rotates at high speed to be tightly locked by the brake pad in an instant. The wheel that has stopped loses all power and steering ability, and “砰”, slammed into it.

In order to avoid this situation, the concept of "point brake" has been adopted, and the brake pedal is quickly and continuously pressed, and the braking force is gradually applied to the wheel. But this is a professional skill after all, and at the same time in such a critical situation, so "point brakes" are difficult to spread among the widest range of drivers. The emergence of ABS solves this problem, and the mechanical control pulse of the electronic sensing device transmits the braking force to the wheel evenly and quickly, preventing the momentary locking of the wheel.

From this point of view, the ABS device is a device for correcting and improving the past bad handling behavior to avoid accidents. Therefore, in order to make this device fully function, only the most thorough and original may be the most "wrong". Brake method to activate this device to save your life. It is to use the above-mentioned method to directly and quickly step on the bottom, and ABS will immediately respond to this sudden burst of braking behavior, thereby playing its due role.

While resolutely stepping on the brake pedal, there is another important part, that is, it must be kept on. When the ABS acts on the wheel, the reaction force of the wheel will also return to the brake pedal. The brake pedal will continuously send a rhythmic pulse, which makes people feel the brake pedal constantly shaking. This is called “brake feedback”. . At this time, if the brake pedal is released, the ABS will sense the end of the brake and naturally stop working. Therefore, the brake pedal must be firmly pressed during the entire braking process, and no vibration should be released.

Next, I will talk about the misunderstanding of ABS. ABS is a brake anti-lock system, so ABS is only to prevent the vehicle from rolling and steering ability under sudden emergency braking conditions. ABS will never shorten the braking distance, so don't expect the vehicle to stop instantly while emergency braking. Instead, actively adjust the direction of the vehicle to avoid the most dangerous collision. The function of ABS is only to give the driver a chance to save himself or even heal at the last minute. If you do nothing, ABS can't help you.

Finally, prompt for some data. When the ordinary car with good condition is braking at 40km/h on dry road, the braking distance is 10m; the braking distance of 60km/h is 13m; the braking distance of 80km/h is 20m; the braking distance of 100km/h is 40 meters.

Know this, then take the time to familiarize yourself with your car, find an empty and safe place, try your ABS, mention the speed just 60km/h, then step on the brake pedal Experience what the legendary "brake feedback", remember the feeling of this pulse jitter; then get off to see your brakes, remember these two long black marks, re-establish a "brake The concept of distance.

In fact, all the electronic control equipment on the car is limited. Each system only controls the specific situation. The vehicle is ultimately controlled by the driver. Don't rely too much on these high-tech equipment, because these devices are not intelligent. It is not all-powerful. It is important to remember that all electronic aided control devices have only one purpose, which is to provide you with more opportunities for self-help and risk-avoiding at a critical juncture. Your life is only in your own hands.
