The black technology of deep digging into the automobile braking system

At present, the common automobile braking system generally includes vacuum boosters, ABS, and electronic stability control systems (ESP/ESC). Vacuum booster When it comes to vacuum booster, I believe many people will ask what it is? Rarely seen, because this vacuum booster is installed behind the pedal, that is, in the engine compartment.

AEB (automatic emergency braking) isTo help you step on the brake to avoid collisions, the car has the ability to be active and safe for the first time, and compared with other technical changes such as the body, it is a hard truth not to crash.

There is not much explanation about the ABS brake anti-lock system. As a car user, you only need to understand its function to prevent the wheel from holding the wheel when braking (making it unable to rotate), causing the vehicle not to turn according to the guidance of the direction wheel, but to be pushed in a straight line by the vehicle by inertia. ABS is to ensure that the car can still turn when braking suddenly.

What is China's own computer system?

1. Galaxy Kirin Operating System: Galaxy Kirin is an open source server operating system developed by the National Defense University of Science and Technology. This operating system is a major scientific research project of the 863 plan. The goal is to break the monopoly of foreign operating systems and develop a set of server operating systems with China's independent intellectual property rights.

2. New Era Operating System: An operating system for high-performance computing developed by the Institute of Computing Technology of the Chinese Academy of Sciences. The New Era operating system adopts a new architecture developed independently, with excellent parallel computing and large-scale data processing capabilities.

3. Red Flag Linux Red Flag Linux is one of the larger and more mature Linux distributions in China, and it is also a famous operating system in China. It has jointly launched AsianuxServer with Linux manufacturers in Japan and South Korea, and has perfect teaching Education system and certification system.

4. China's own computer operating system includes: Deepin Linux (Deepin) linux distribution is a Linux-based operating system developed by Wuhan Shenzhidu Technology Co., Ltd., which focuses on users' daily office, learning, life and entertainment experience. To, it is suitable for laptops, desktop computers and integrated computers.

5. Galaxy Kirin Operating System Galaxy Kirin (KylIn) is an open source server operating system developed by the University of National Defense Science and Technology. It is safe and reliable, supports network redundancy, and meets the network needs of different scenarios. It is also compatible with applications on the Linux platform and has powerful Chinese processing capabilities.

6. Common computer operating systems can be divided into three types, namely Windows, which has the highest popularity rate in China, developed by Microsoft. Windows 7, Windows 8 and Windows XP in the series are all household names with a very high popularity rate.

What are the new scientific and technological products created by scientists

1. Radar: Modern radar is designed by scientists based on bats.Hull: The ancients invented the hull imitating the shape of fish, imitating the pectoral fin and tail fin of fish to make double oars and single sleds. Airplane: People use the flying principle of birds to make airplanes.

2. Electronic frog eye is actually a kind of electronic eye. Its front is actually a camera. After imaging, it is transmitted to the computer device for display and preservation through optical cable. Its detection range is fan-shaped and can rotate, similar to frog eyes. Bionicist Locke invented the electronic frog eye based on the principle and structure of the frog eye.

3. Robot Robot is a machine device that automatically performs work. It can not only accept human command, but also operate pre-arranged procedures, and act according to the principles formulated by artificial intelligence technology.
