Chapter 594 ADAS System

To be honest, Zhou Fei’s understanding of the DAS driving assistance system is still at the initial stage. He thinks that the DAS system is just the lowest form of automatic driving, and its function is not so powerful, but he did not expect that after Ramsey’s transformation, it can So smart, even drunk driving can be detected?

"ADAS system?" Zhou Fei muttered something in a low voice, and then said with some uncertainty, "Does this refer to the advanced driver assistance system?"

"Yes, ADAS is the abbreviation of Advanced Driving Assistance System. This will be the advanced form of DAS system, and it will also be the project we will focus on in the next stage." Ramsey nodded with a smile.

The original DAS system can only respond passively to the road conditions during driving, but once it evolves to the ADAS system, various functions will be more active, which can further improve driving safety, which is also a major contribution to autonomous driving. It can be said that it is the prelude to automatic driving.

"The drunk driving warning tested by Mr. Zhou just now is actually just a very rough test result. As long as the alcohol concentration of the overflow exceeds the reference value set by the system, the vehicle will issue a warning. Similar results have appeared, so this function is still very imperfect and cannot be accurately judged.”

Ramsey paused and continued, "In the ADAS system we developed, the detection of drunk driving will be more accurate. The system will collect information through multiple sensors, and then make a comprehensive judgment. As long as the driver's alcohol exceeds the standard, Then the vehicle cannot be started unless the driver is replaced. Of course, these functions are just an alternative to automatic driving. Once automatic driving is realized, there will be no need for drunk driving detection.”

"The realization of automatic driving still has a long way to go. The solution you mentioned just now has great application value. I support your efforts in this area." Zhou Fei made no secret of his appreciation for this technology, In any case, this is a big step forward in the history of automobile development.

"Well, let's finish the test first. I want to know more about the ADAS system you mentioned."

"Okay, then let's continue with the test, Mr. Zhou can get in the car now." Ramsey nodded.

Because the alcohol in his hand had evaporated, when Zhou Fei got into the car this time, there was no warning sound from the car.

After Ramsey's transformation, the current DAS system has integrated a number of active safety technologies, including forward collision warning system, lane departure warning system, blind spot detection system and adaptive headlight system. When the driver's attention is shifted instantly, or when the vehicle in the blind spot is not seen, the DAS system will take effect and make a series of reactions to avoid accidents.

In addition to showing its prowess in safety, the DAS system will also play a role in maneuverability and comfort, increasing driving fun.

After fastening the seat belt, Zhou Fei followed the test rules and began to drive around the test track. Compared with the previous Tesla without the DAS system, the current Tesla has a better driving experience. Well, the vehicle seems to have a spirituality, it can automatically sense Zhou Fei's next operation, and then respond accordingly.

Moreover, once it detects that the road ahead is sandy and gravel, the vehicle can even automatically slow down and drive across this road in a relatively stable manner, ensuring both safety and comfort.

After two laps of the complete test, Zhou Fei smiled and got out of the car, and gave Ramsey a thumbs up, "It's very well done, the car with the DAS system, and the car without this system, It's totally two different things!"

Now it seems that it was worthwhile to spend all the time to acquire Human.

"Thank you Mr. Zhou for your affirmation." Ramsey replied with a smile.

Afterwards, Ramsey took two copies of the icons from the testers and handed them to Zhou Fei, "Mr. Zhou, this is the data report of the two vehicles tested. You can take a look. After the DAS system is installed, the power of the vehicles Performance, maneuverability, etc., have been significantly improved, and the graph looks smoother."

Zhou Fei took the document and compared it carefully. Indeed, as Ramsey said, the comparison between the two charts is very obvious, which means that the effect of the DAS system is very significant. It will be used on all Tesla models in the future. , can be promoted.

"How do we master the production technology of this DAS system now? Can it be fully independently mass-produced?" Zhou Fei asked immediately after reading the report.

For such a core technology, Zhou Fei does not want it to be outsourced.

"The production of the DAS system is not difficult. As long as the core components can be produced independently, other accessories are not a problem at all. I have investigated the capabilities of Feichi Automotive Electronics. This DAS system can be produced by Feichi Automotive Electronics. I have prepared the relevant materials. Well, if Mr. Zhou needs it, I can ask someone to guide them at any time." Ramsey replied with a smile.

"That would be great. When I go back this time, you can go with me. I hope that from next year, all electric vehicles under the group can be equipped with this system. Wait for the production capacity of DAS. After it is put up, I hope this system can become a standard configuration." Zhou Fei couldn't help saying excitedly when he heard this.

From the construction of the factory to the purchase and installation of equipment, all these require a certain amount of preparation time. The sooner the preparation is made, the sooner the DAS system can be mass-produced.

And this system will undoubtedly greatly increase the competitiveness of all electric vehicles under Tesla and even Mercedes-Benz Group!
"Okay, I'm fine." Ramsay agreed with a smile.

"Then let's go back first. After lunch, I will report to Mr. Zhou about the situation of the ADAS system in detail." Ramsey looked at the time, and then added.

After lunch, Zhou Fei didn't even bother to take a break, and directly took Ramsay to the office. About the ADAS system, Zhou Fei couldn't wait to learn more.

"Mr. Zhou, please take a look. This is the specific structure of the ADAS system I initially designed, and the structure of the current DAS system is on the left." Ramsey turned on the computer and pointed to the three-dimensional diagram on the screen.

However, Zhou Fei doesn't know much about the structure of electronics after all. In his opinion, there is not much difference between the left and right structures.

"In fact, there is not much difference in structure between DAS system and ADAS system, and the working principle is similar, but I have grafted many other module components on the original DAS system, and then integrated them into an ECU. In addition to the current ADAS system, the functions are more powerful than before."

Seeing that Zhou Fei was a little confused, Ramsey continued to explain while clicking the mouse.

"Tell me first, if the ADAS system can be successfully developed, what functions can be realized." Zhou Fei asked directly.

Technical issues are what Ramsey needs to consider, and he only wants results.
