Chapter 168 The Effects of ABS

The designed ABS system is mainly composed of three parts: wheel speed sensor, controller and actuator. The controller includes ECU and ABS, and the actuator is a special envoy==special ABS pump.

This system needs to be assembled on the brake system of the vehicle in order to play a role in the driving process, which means that if such a configuration is to be released on the Golf, Zhou Fei has to redesign this system. For the braking system of the car, arrange the distribution of the brake oil pipes.

This work involves more technical content, and the design part of the original braking system does not need to be changed much.

But even changing the assembly process is a relatively cumbersome task, and now that the golf sedan has entered the testing stage, and a new factory is also under construction, if changes are made rashly, there may be uncontrollable factors.

So after much deliberation, Zhou Fei decided to temporarily open the ABS system to the public as an optional configuration. Consumers can choose whether to match this system according to their own needs. It is a conventional configuration and is promoted and used on all models of Mercedes-Benz.

However, it is only the beginning to complete the design of this system, and the more important thing is how to produce ABS.

With the current level of electronic technology development in this world, it is not difficult to produce such a system as long as there are schematic diagrams, but the key point is that Zhou Fei is now facing a difficult problem, whether to outsource the production of this system, or Say, build your own production line and produce ABS yourself.

Both have advantages and disadvantages. If outsourced, it can save investment funds and greatly reduce the production cycle. The disadvantage is that Zhou Fei has to sell the ABS technology to others.

You must know that at this time, ABS is a completely new technology, and once it is launched, it will definitely become a milestone in the history of automobile safety development. No car manufacturer can escape the fate of assembling this system.

In other words, ABS can exist as a company's core technology!
Zhou Fei felt that it was a loss to sell this technology to other automotive electronics manufacturers!

"Anyway, Mercedes-Benz is also going to enter the automotive electronics market in the future, so we can simply use the ABS system as a stepping stone and start an automotive electronics company by ourselves!"

Zhou Fei gritted his teeth and felt that it was the most cost-effective to produce the ABS system by himself.In his plan, Mercedes-Benz is not only a complete vehicle manufacturer, but will also span various fields such as automotive electronics, auto finance, car leasing, and auto power in the future.

Now that the ABS system has been developed, take this system as an opportunity to directly enter the automotive electronics market!
As long as this system can be successfully popularized, the sale of the ABS system alone will be enough for Feichi to make a large profit. The auto parts supplier giants Bosch and Continental Electronics in the previous life are the best examples!
Therefore, the current investment funds are nothing compared to the future income!
After thinking about this point clearly, Zhou Fei also convened a high-level meeting of the company immediately to discuss the possibility of investing in automotive electronics and the specific implementation plan.

However, when explaining the investment goal this time, Zhou Fei encountered a lot of trouble, because these people did not understand what is called ABS anti-lock braking system.

"When a normal vehicle brakes, the left and right steering wheels are directly locked, and the adhesion between the wheels and the ground is greatly reduced. A little lateral force can easily cause the vehicle to slip, and even more The important thing is that the steering wheel cannot be turned at this time, which is especially likely to cause serious traffic accidents, everyone should be very clear about this."

Zhou Fei made a simple diagram on the whiteboard in the meeting room while talking. Without the ABS system, the braking of the vehicle is continuous. As long as the brake is stepped on, it will continue continuously.

"And the ABS system I just mentioned is to alleviate the situation where the wheels are directly locked. When we step on the brakes, the car is in a state of rolling and sliding instead of sliding like this, rolling and sliding. It can ensure that the adhesion between the wheel and the ground is always maintained at the maximum value..."

Immediately afterwards, Zhou Fei drew a braking route map equipped with the ABS system on the whiteboard. It was different from the one on the side. After the ABS system was installed, the braking marks of the vehicle were intermittent, which meant that the wheels were not Has been in a deadlocked state.

The wheel speed sensor will precisely control the vehicle according to the set speed threshold. Once the vehicle speed is lower than this threshold, the ABS system will take effect to automatically reduce the braking force to prevent the wheels from being directly locked.

During the working process of the ABS system, it can reach 60 to 120 times per second, so that it can avoid the direction out of control and the wheel slipping during emergency braking, so that the wheels will not be locked during braking, and the tires will not be in contact with the ground at one point. friction to increase friction.

Under the action of the ABS system, the braking efficiency of the vehicle can reach more than 90%. At the same time, it can also reduce the consumption of the brakes and extend the service life of the brake drums, discs and tires twice.

根据实验数据表明，装有ABS的车辆在干柏油路、雨天以及雪天等路面防滑性能分别达到80%到90%、10%到30%以及15%到20%，极大的改善了车辆的安全性能。

"According to Mr. Zhou, is this ABS system equivalent to keeping the vehicle in a state of spot braking, braking the car at regular intervals, then releasing it immediately, and then braking again... This cycle continues? Zhang Xiang on the side asked with a half-knowledge.

"It can be considered that ABS is equivalent to the function of point braking. It just changes the mechanical point braking control into electronic control, thereby reducing the braking distance." Zhou Fei smiled and nodded. Zhang Xiang's understanding is more accurate. Easy to understand.

With such an explanation, many people here have a general understanding of the specific working utility and working principle of the ABS system, which makes many people feel very excited.

"So, as long as the ABS system is installed, many traffic accidents can be avoided?"

"This is a major invention, it will definitely surprise the whole world!"

"If it can be popularized and used on a large scale, will Mr. Zhou be awarded a Nobel Peace Prize?"

…………

Listening to the ridicule of these people around, Zhou Fei couldn't help but smile, and then said, "This system does not guarantee that the braking distance will be reduced. If the braking is too fast, the system will not respond in time, and accidents will still occur. It can only be said that this system can greatly reduce the probability of accidents.”

There is nothing absolute in this world, and what people can do is to get infinitely close to "absolute" and keep working hard in this direction.

"Just talking about it, maybe you don't understand it very well. Let's make a set of ABS first and install it on the vehicle. Then we will do a comparison test on the spot, and you will know how effective the ABS is." Zhou Fei After a pause, he continued.
