Chapter 642 Customized Standards

A researcher who was about to pour water saw Lai Ping and said hello: "Hello, Mr. Lai."

"Yeah." Lai Ping nodded and replied.

After hearing this employee's voice, everyone in the system development department knew that Lai Ping was here.

Song Changsen quickly got up from his workstation and walked to Lai Ping.

"Mr. Lai, you are here." Song Changsen said with a smile.

Song Changsen is 38 years old and comes from Bingcheng. He has a strong build and a height of 1.83 meters. He has a face with a Chinese character. He looks very simple and honest, but his personality is actually a ghost and he is very strict with his subordinates.

He once worked as an engineer at FAW-Volkswagen and was recruited from FAW-Volkswagen by Luo Ying.

This character was developed while he was working with the engineers at Volkswagen.

Because car safety is a matter of life and death, this also makes him very rigorous in what he does.

"How is the development progress of the control system?" Lai Ping asked.

"There is nothing wrong with the software of the central control system. Using the Pangu system to control the system is very stable. Other situations are not ideal. The main problem lies in the MCU chip.

An electric vehicle requires nearly a hundred MCU chips, and various parts of the vehicle require chips from different manufacturers. However, the development interfaces and commands of each manufacturer are different, which also greatly increases the difficulty of controlling the system.

Moreover, when the chips are different, when analyzing the timing and executing instructions, it is easy for instructions to be inconsistent.

To make the entire system coordinated, more code is needed.

Once the code is redundant in multiple systems, it will become very serious, and the response speed of the entire system will become very slow.

Although the performance of Nuwa A2 can already meet this demand.

But in the long run, this solution is not a good solution, so I suggest working with Kirin Semiconductor to jointly develop a universal MCU.

In addition, I hope that the company can join forces with other component manufacturers to jointly customize a standard and protocol.

This will not only greatly reduce development costs, but also greatly reduce the difficulty of future development," Song Changsen said.

From body powertrain, to body control, infotainment, assisted driving, from engine control unit, to wipers, windows, electric seats, air conditioning, tire pressure sensing and other control units, the realization of each function requires complex technology.

Chipset support, in which MCU plays the most important role.

MCUs account for about 30% of all semiconductor devices equipped in a car. On average, each car uses hundreds of MCU chips.

It is necessary to realize various application scenarios in the car while ensuring sufficient safety. When using MCU chips from different manufacturers, the safety and stability of the car control system will be greatly reduced.

"Just follow the method you mentioned. I will communicate with the manufacturer and set the relevant standards first, and then start research and development." Lai Ping thought for a while and replied.

If we look at the traditional situation, he would not agree to this request. Car-level chip certification is too troublesome.

Because the standard of automotive-grade chips is much higher than that of consumer-grade chips.

1. The working environment is harsher: Compared with consumer chips and general industrial chips, the working environment temperature range of automotive chips ranges from minus 40 to plus 155 degrees Celsius, and they are susceptible to wide width, high vibration, dust, and electromagnetic interference.

2. High reliability and safety requirements: Most cars are designed to last about 15 years or 200,000 kilometers, which is longer than consumer electronics products. Under the same reliability requirements, the more components and links the system consists of, the greater the impact on the composition.

The reliability requirements of the components are higher.

3. The certification process for car-grade chips is long: it takes about 2 years for a chip to complete car-grade certification, and it generally has a supply cycle of 5-10 years after entering the supply chain of car companies.

However, the MUC chip is the core of the core of electric vehicles. If you cannot master this technology, you will easily be blocked by the enemy in the future.

Rather than doing this, it is better to develop it yourself.

In addition, there is the problem of docking other components. It is very troublesome to develop different protocols and different ports. It will take at least one or two years from development to testing to final implementation.

In this case, it is better to customize a standard yourself and then develop it later.

It is much easier to tear down and start over than to adapt to others, and most importantly, safety is also much improved.

But in the long run this is very necessary.

Upon hearing Lai Ping's words, the R&D personnel present wanted to shout: Long live Mr. Lai.

Because it is really a headache to use different chips for development. If there is a slight mistake, you have to start over.

Because the control system is very likely to cause the entire vehicle to be paralyzed due to an error in one link.

If they make a mistake once, they have to do it all over again. This is too troublesome for them. It takes them two or three years to figure out the control system.

...

After Lai Ping left the R&D room, he went to Kirin Semiconductor.

He had to personally take charge of the joint development with semiconductors. Song Changsen was just the director of the R&D department. To put it bluntly, Song Changsen's level was not high enough.

After seeing Lai Ping, the receptionist of Kirin Semiconductor quickly stood up and shouted: "Good afternoon, Mr. Lai."

During the annual meeting, the bosses of each branch had to give speeches on stage, so the front desk of Kirin Semiconductor recognized each other at a glance, and Lai Ping's dress was so handsome and individual.

It's unrecognizable that she could be laid off and come back to work again.

"Is Mr. Guo here?" Lai Ping asked.

"Yes, let me ask Mr. Guo if he is available." After Yu Liwei said that, she picked up the phone and dialed Guo Kezun's number.

After getting Guo Kezun's reply, Yu Liwei took Lai Ping to Guo Kezun's office.

Yu Liwei came to the door of Guo Kezun's office and knocked on the door first.

"Come in."

Yu Liwei opened the door and Lai Ping walked in directly. After Lai Ping walked in, Yu Liwei closed the door.

"Mr. Lai, why do you have time to come to my place?" Guo Kezun asked with a smile.

"I encountered a problem over there, so I had to come to you for help." Lai Ping replied with a smile.

The two sat at the same table at the annual meeting, so they knew each other, and since they were about the same age, they had many topics in common.

"I still have a problem that you can't solve, Mr. Lai. How can I help you?" Guo Kezun asked.

Lai Ping told them about the situation they were encountering now, hoping that Guo Kezun could join their project.

"Mr. Lai, you have found the right person this time. I just met with Mr. Cao yesterday. I told him that I planned to enter the MCU chip industry. I was also thinking about whether to cooperate with you. I didn't expect you to come to the door today."

Already." Guo Kezun said with a smile.

"Mr. Guo, then we have reached an agreement?" Lai Ping asked with a smile.

"It's a pleasure to cooperate." Guo Kezun extended his hand and said.
