He Xiaopeng used a Weibo to end the AEB dispute between himself and Yu Chengdong.
On November 9, He Xiaopeng, CEO of Xpeng Motors, posted: "This morning, I discussed the technical route with Lao Yu, and I believe that the contention of this technology will benefit users in the end." We will also expand the AEB function through OTA, thanks to Lao Yu's advice and generosity, sometimes it is easier to become good friends after misunderstandings. ”
The title has changed from "friendly businessmen" with guns and sticks to "Lao Yu", and the recent controversy has been called a "misunderstanding". He Xiaopeng's post means that the AEB dispute ended in a handshake.

Xpeng Motors pushes AEB-related upgrade packages
At the same time as ending the debate, according to the owner, Xpeng Motors also pushed the upgrade package of "Xmart OS 4.4.0 Pioneer Edition 4".
According to the updated documentation, it includes: the new "Intelligent Driving" application, perception ability upgrade, Al driving intent, voice reminder experience optimization, automatic emergency braking (AEB), driver assistance function settings, parking assist, intelligent parking assistance (APA) and other functions.
In the Automatic Emergency Braking (AEB) upgrade project, Xpeng introduced: optimized the safe braking performance for traffic participants such as vehicles in front, motorcycles, bicycles, or pedestrians in longitudinal crossing scenarios, and triggered more accurately and timely; Optimized for scenarios such as large trucks, lateral stationary vehicles, and children traversing, triggering more accurately and timely; Optimized the safe braking performance in scenarios such as following the vehicle in front and quickly cutting out of the vehicle in front, and the triggering is more accurate and timely. Optimized the safe braking performance of vulnerable traffic participants such as motorcycles, bicycles, or pedestrians in front of them, in scenarios such as sudden stops or turns, and triggered more accurately and timely. The safe braking performance in the starting and cornering scenarios of the white car has been optimized, and the trigger is more accurate and timely.
After the upgrade, whether the AEB test score of Xpeng Motors can be improved remains to be verified.

He Xiaopeng and Yu Chengdong scolded each other
He Xiaopeng and Yu Chengdong's exchange of anger about AEB began with an evaluation video.
In July this year, an automotive vertical media conducted AEB tests on a number of models such as Wenjie, Xpeng, Volvo, and Tesla in 8 scenarios such as "adult ghost probe" and "non-motorized vehicle crossing", and the test results showed that Huawei's ADS 2.0 equipped with Wenjie models is based on the GOD network of multi-sensor fusion including lidar, millimeter-wave radar, and visual fusion, and performed well in the AEB test. The content of the video was quoted in several press conferences.
On October 24, at the Xiaopeng Motors Science and Technology Day, He Xiaopeng wrote in PPT: "The king with a strong mouth may affect public opinion, and only by really engaging in technology can we create the future."
On November 1, He Xiaopeng opened fire directly in an interview with the media: "Friends talked about AEB, I think 99% of it is fake, it is fake, and those propaganda are not officially released by the company, they are all from small videos." Our people also went to ask, its AEB can't be driven at all, and there are too many cases of false braking on the road. ”
He Xiaopeng also said that friends treat users as guinea pigs, "At present, when talking about AEB in the industry, it mainly talks about vertical AEB; When triggered, the speed should be within 60 km/h in most cases. If the speed is too high, once the brake is mistaken, it will be a huge shock to the user, which is simply unacceptable. ”
Combined with the context, it can be seen that the "friend" here is Huawei. On the evening of November 3, Yu Chengdong posted 4 pieces of content in the circle of friends to hit back at He Xiaopeng. "Even what AEB is, there are car companies who don't understand it at all! It's almost the same as someone saying that intelligent driving is flickering! ”
Yu Chengdong said that some people lack basic understanding of the technological progress and future development of the industry, "Some car companies are busy doing intelligent driving all day long, and the AEB active safety test results are very poor. ”
On November 7, the test results of an automotive vertical website were obviously unfavorable to Xpeng Motors. The website conducted a static fake car identification test on the AEB of many models such as the M5 and Xpeng G6, and the test results showed that many of the results of Xpeng Motors were not satisfactory, while the performance of the "Huawei series" model was "far ahead".
On November 8, He Xiaopeng replied to the test and said that "friends have worked hard".
Regarding the performance of Xpeng Motors in the test, He Xiaopeng explained, "In the five-star safety evaluation in China and Europe, there are many strict restrictions on the AEB environment, mainly in low-speed dynamic and certain light environments. Xpeng and many vehicles have received or are about to get double five-star safety evaluations, and even some scene scores are ranked first. However, if we follow the test methods in some videos, because some of the scene evaluation strategies have been revised and adjusted to a certain extent, if we also use it to test all vehicles that have achieved five-star safety, I believe that most of the results are the same. ”
On November 9, He Xiaopeng issued a message of thanks.
The automotive community talks about AEB
This controversy also attracted many insiders to participate. Geely Radar Automobile executives issued a document saying that the core of AEB is safety, and the safety guaranteed by AEB is by no means the safer the higher the braking speed, because when AEB is triggered, it is already in a very dangerous situation.
"The maximum braking deceleration of AEB can reach 1G (1G is the feeling of the falling of the jumping machine), and enabling AEB full braking at high speed is easy to cause vehicle instability, especially when AEB is accidentally triggered, the consequences will be more serious. Therefore, the maximum braking speed range of AEB collision avoidance in the industry is 50km/h-60km/h, and the current measured data of Tesla Model Y is 50km/h. ”
He believes that the real AEB safety is to cover more emergency braking scenarios on the premise of not triggering AEB by mistake, rather than simply pursuing the maximum braking speed of AEB. 60km/h has already covered most use cases, and for higher speed scenarios, we choose to use ACC, LCC and other functions for pre-comfortable braking, rather than taking the user to a dangerous scenario where AEB must be triggered.
In a live broadcast on November 7, Zhu Xichan, a professor at the School of Automotive Engineering of Tongji University, said that AEB and intelligent driving are two concepts, and the algorithm of intelligent driving does not include the AEB algorithm, but two teams and two algorithms. "Autonomous driving is good, not necessarily AEB is good, AEB is not necessarily good autonomous driving". At the same time, he also believes that getting a double five-star in C-NCAP and E-NCAP can prove that AEB is doing a good job. ”
Regarding Huawei's performance in the AEB function, Zhu Xichan believes that Huawei is a top student, and it has done "super-outline Olympiad problems" on the AEB topic, which does not mean that Xpeng Motors is a scumbag. Professor Zhu talked about the current situation, while Dr. Zhang Kangkang, a doctor from Tsinghua University's Department of Automotive, talked more about the future prospects. "Companies with good autonomous driving can give AEB the ability to perceive intelligent driving and do it better."
According to the delivery data, Xpeng Motors delivered a total of 20,000 new cars in October, an increase of 31% month-on-month and a year-on-year increase of 292%, setting a new historical record for single-month delivery and resuming growth for 9 consecutive months; Cumulative deliveries in the third quarter were 40,000 units, up 72% from the previous quarter. With the controversy over and the push of the upgrade package, Xpeng's sales are expected to grow further.
