00:00 Recently, huh, Yu Chengdong of Huawei and He Xiaopeng of Xiaopeng Motors had an aerial battle
00:04 The topic point comes from discussions on AEB. What about He Xiaopeng
00:07 Questioning the content of Huawei AEB was also cheating, while Yu Chengdong questioned that He Xiaopeng didn't understand AEB
00:12 I have to say, Huawei's influence is really huge because AEB was born
00:16 It's probably 20 years younger. It's not a new word or technology in itself
00:20 Well, this kind of airborne conversation has sparked everyone's discussion about AEB
00:24 I found that many industry insiders, including ordinary consumers, were involved in this discussion or war
00:29 They expressed their opinions one after another
00:31 Of course, some opinions from outside the industry aren't necessarily entirely true
00:34 So let's first review what AB is. Its full name is automlance braking literally means autonomous emergency braking
00:41 So why has it been mentioned frequently by consumers in the past two years
00:44 Isn't it because of the rise of adas
00:46 It's an important part of adas, and the threshold is getting lower
00:49 Almost now you can buy a model with AB for 100.1 million
00:53 uh
00:53 At the beginning of AB, it was mainly an active safety configuration for some medium to low speed situations
00:58 For example, what we commonly call ghost probes, or similar operating conditions
01:02 With the development of AEB
01:03 Actually, the current European ENCAP includes the domestic NCAP
01:06 In fact, AEB has detailed standards and regulations. They include how to evaluate emergency braking actions taken on pedestrian bicycles, motorcycles, and vehicles
01:16 But ah, these regulations are all relatively basic
01:20 Mainly used to evaluate test scores
01:22 Until now, AEB doesn't have a fully defined standard
01:26 Or it can be expanded infinitely upwards according to its literal meaning
01:29 So whether to stop at 60 kilometers per hour, or 90 kilometers or 120 kilometers
01:35 Every vendor has their own strategies and ideas
01:37 I also probably read online reviews. There is still a big difference in opinions between ordinary users and car industry insiders
01:44 Generally recognized by consumers
01:45 The knowledge is relatively simple and crude; most of it is entangled at the speed point where AEB works
01:51 I think the higher the speed and the more it stops, then the more effective this system is
01:55 Well, of course it is, because this is the number that most intuitively reflects emergency braking capability
02:00 Well, some engineers and people in the industry have relatively neutral views on AEB
02:04 Even some opinions are contrary to the average consumer
02:08 Engineers usually consider AB's algorithm and how difficult it is to calibrate
02:12 Including predicting clutter, ah, etc., and how to avoid incorrect braking due to incorrect identification
02:17 One interesting phenomenon is that many ordinary people think it would be better to stop by mistake
02:23 Only in this way can safety be guaranteed
02:24 However, in the opinion of people in the automobile industry, the opposite is true. They think it would be better not to brake by mistake
02:30 After all, it is still difficult to achieve 100% accurate object recognition
02:35 I believe many driving friends have also triggered the emergency braking function
02:38 Some have indeed avoided danger
02:40 Some, uh, may have added risk, such as when you are distracted
02:44 If a ghost probe appears, or there is a relatively slow moving vehicle ahead
02:47 AEB can indeed slow down and even avoid collisions
02:50 However, if during intense driving, the driver is fully capable of performing some parallel operations
02:55 But because the system detected that the speed was too fast compared to the vehicle in front
02:58 Then maybe during the process of connecting you will rashly take a braking action
03:02 Instead, it will make your driving dangerous
03:05 Well, there are many other misunderstandings, ah, I don't know if you've experienced them
03:08 So many friends who love driving actually want to turn off AEB
03:12 Judging from the test results, Huawei does have the ability to brake at higher speeds than other manufacturers
03:17 Let's put this situation in actual driving, if you really get carried away
03:21 No action at all
03:22 AEB can indeed avoid collision with the car in front, then what about the rear car
03:26 Once AEB works at high speed, it will inevitably intervene to control the vehicle sooner
03:31 At this time, if the driver takes over and changes lanes, the vehicle often continues to brake at this time
03:36 Then you can't control the vehicle according to the driver's operation; on the contrary, it will increase the risk by one more time
03:40 Well, this is a point mentioned by many engineers, I don't know if you can get my points
03:44 That's why many automotive engineers aren't too excited about this AEB discussion by Huawei
03:49 They are more trying to convince everyone through some calibrated strategies and ideas
03:54 Also, I think many people have overlooked one point, that is, any assisted driving behavior in vehicles now requires people to take the lead
04:01 not a machine
04:02 It seems that when everyone is discussing this issue, it seems like people have lost their hands and feet
04:08 At least now, AEB can only be considered a secondary safety configuration
04:12 There won't be any answers to this debate, because AEB's standards are inherently vague
04:15 Every manufacturer also has their own understanding of calibration, and I don't think there's anything wrong with He Xiaopeng's understanding of AEB
04:21 But if you say they cheated, they shouldn't have, right
04:23 But what
04:24 It is undeniable that Huawei's ability to recognize scenes like this is indeed superior to other products
04:30 Including Volvo, which surpassed the first promotion of city safety aeb features
04:35 Later, we actually also wanted to have some in-depth communication with PhDs, including UMC, these manufacturers that specialize in ADAS or AEB calibrations
04:44 Check out their AEB strategies and ideas
04:48 So what is your opinion on this matter
