Two sets of engines made of polyethylene and the steering wheel were carried into the conference room.

The ratio of these two sets of models to the actual object is about 4:1, which is very suitable for explanation.

"Please look at Shanmao. This is the 2.5-liter V6 direct injection engine and electronic control assembly of Audi A8. The color of the electronic control part is orange. This set is originally designed by Volkswagen."

With Chen Jianfeng's explanation, Su Yuanshan had already stood up, and seeing him standing up, everyone surrounded him.

"Audi A8 only uses the latest electronic anti-theft system provided by Siemens this year, using the UESTC9432 series microcontroller..." Speaking of this, Chen Jianfeng paused, coughed gently, and said with a calm wind: "I have made a small contribution to this microcontroller."

——He also came from the Electrical Science Department, but he was a few years later than Qin Weimin and others. He did not catch up with Yuanxin's entrepreneurship, but he caught up with the continued research of the Electrical Science Department on the UESTC91 series microcontrollers later, participated in the scientific research group of 32 microcontrollers, and also gave a beautiful master's thesis. After graduation, he also directly joined Yuanxin's YX architecture team.

"Using a thirty-two-bit processor, in theory, they can realize a cipher combination of 2 to the power of 32. It is much higher than the resistive controller that GM is still using... "

Seeing Su Yuanshan listening with a serious look, Chen Jianfeng suddenly thought that Mr. Shan didn't even have a book, and was afraid that he had no idea about the engine electronic anti-theft system, so he quickly explained: "Mr. Shan, let me introduce to you the latest IMMO system at present in Siemens."

"First, after inserting the key, twist the switch, and then there is a row of coils in the keyhole position that will release electromagnetic waves and activate the semi-active RFID system inside the car key. This is the thing."

Chen Jianfeng said and pointed to the key handle on the model: "Then the chip sends out an encrypted data signal, exchanging and verifying and matching data with the EMS system (engine control unit) all the way. If the verification is passed, the EMS system will start working."

"If the match fails, it cannot be started."

"And, as I said just now, they use 32-bit chips as the main control chip, so they can realize a password combination that cannot be guessed in theory."

"Well." Su Yuanshan nodded. Although he didn't know much about IMMO (Immobilizer, the engine was placed in the locking system), he was engaged in chip and software design... This anti-theft system principle is really simpler than doing a primary school mathematics problem: "It sounds good, then what?"

"Then...we find this thing a bit unreliable."

Su Yuanshan nodded, thought for a moment and said, "It's indeed a bit unreliable. The 400 million-time combination password can be impossible to guess and not repeated. However, when it is started, the RF signal can be intercepted and collected. Then you can just copy the RF signal directly and deceive it."

As soon as these words were spoken, Chen Jianfeng immediately blinked hard a few times, and the other people present also had different expressions.

Especially Li Junyou and Sun Xiaochuan, in this conference room, they are just serious cars, not chip and electronic circuit design.

When they fully understood the principle of this anti-theft system, they both spent a lot of effort... But Shan Yuan was so good. It sounded like he had already understood this principle in an instant, and even thought of a cracking method casually.

"Yes, this is the insecure point, so we use rolling codes - adding an encrypted code that changes instantly generated by the algorithm to the matching code. Even if the signal is intercepted, it cannot be started through copying."

Chen Jianfeng said and pointed to the blue model next to him: "Mr. Shan... Look here, in addition to controlling the ignition system, the oil circuit system, instrument system, and even the door and window locks of the entire vehicle have been integrated into the EMS system."

"And, the inability to complete the ignition start is just the most basic function. The subsequent door and window locks, horn warnings, and even automatic alarms, automatic sending and positioning can be arranged - we just can't make a move for a while."

"And these are just the beginning."

At this time, Wang Xiaochun, who is responsible for the automatic navigation function, interrupted with a smile: "Mr. Shan, let's think carefully. If we don't care about the cost, we can also turn the on-board navigation into a smartphone that can access the Internet, and manage the various data of the car through the database. As long as we think about matching the network in the car, there will be infinite possibilities. Anti-theft has become the least factor that needs to be considered."

"I guess what a mobile phone can do at that time, can you do what a car do?"

Listening to everyone talking, Su Yuanshan felt a little emotional - it seems that Yuanxin’s people can indeed bring innovation without the pressure of "KPI".

"Well, that's right. Of course, cars will also develop towards intelligence in the future." Su Yuanshan stopped everyone with a smile: "But we know that the automobile industry is different from mobile phones. Compared with advanced technology, it cares more about safety and is absolutely safe. This is why Mr. Wang from Suoxin has never come here."

Speaking of Wang Chuanfu, Su Yuanshan felt even more moved - the so-called "Road" is easy to change and his nature is hard to change. Even if the wings of Yuanxin's discs have already flapped out of a tsunami, when Su Yuanshan mentioned Wang Chuanfu's desire to build a pure electric vehicle, Wang Chuanfu's eyes became shiny as soon as they were "brushed".

Obviously, Lao Wang has always had a car dream.

Therefore, Suoxin has been insisting on both hands in the past two years, and has been very tightly catching car batteries - and even if it is not for the "car dream", and simply to expand the lithium battery market, it has to promote car power batteries - just like an LCD panel, how many mobile phone orders can a TV be used as?

Now, the car's power battery has finally completed safety tests, which also means that electric cars can be put on the agenda.

Seeing that he had talked about the car, Li Junyou became excited again: "Mr. Shan? What type of electric car do you build?"

"Of course it's a supercar!" Donald understood without translating it now. He didn't care about his identity or the team leader who came to cooperate with TI, and immediately shouted: "Su! Supercar!"

When Li Junyou and Sun Xiaochuan were stunned when they heard the supercar, but the others obviously had their eyes shining! They all looked at Su Yuanshan with anticipation.

"Well, yes, supercar."

Su Yuanshan nodded with a smile.

"good!"

Headed by Donald, including Chen Jianfeng, Wang Xiaochun and others, all applauded.

Sun Xiaochuan and Li Junyou also applauded with everyone, but there was a little more worry in their eyes.

But then, Sun Xiaochuan pursed his lips and nodded constantly: "Yes, supercars are obviously the type that is most suitable for using the cutting-edge technologies of the current institute. After all, the cost is too expensive... Only people who can afford supercars will not care about the price."

"Mr. Sun, this is just one aspect." Chen Jianfeng glanced at Sun Xiaochuan and explained: "Only supercars can reflect Yuanxin's biger."

Sun Xiaochuan smiled slightly, and naturally he knew that the people who came from Yuanxin were all arrogant and did not intend to say anything. Instead, he immediately came to the perspective of the chief engineer to consider the problem.

"But the primary problem of supercars is to run fast - can electric supercars compare with today's traditional supercars in overall performance?" As soon as he finished speaking, Sun Xiaochuan paused and immediately added: "I believe that if the acceleration of 100 meters is 100 meters, the electric motor has an advantage over the fuel engine, but what about after 100 meters?"

"And, pure electric cars also mean that we have to give up all the transmission technology of traditional fuel vehicles and develop a new set of speed control technology ourselves," Sun Xiaochuan smiled bitterly: "We don't even have to copy homework - the so-called hybrid car launched by Toyota last year is essentially a fuel vehicle."

——He is not a person who is afraid of difficulties, but this difficulty seems to be a little too great.

Su Yuanshan glanced at Sun Xiaochuan deeply.
