Previously, there has been a lot of discussion about BYD's intelligent driving level. Many people's view is that BYD has a high level in the field of three electrics, but it may encounter Waterloo in the second half of intelligence. I think the main reason for this kind of ** is that BYD has not really shown this ability to the outside world before.
Recently, BYD's Yangwang U8 completed the AEB test of 130KM H for the safety braking of static fake cars on the Internet. From ***, you can also see that the AEB looking up at the U8 can also achieve 110km h of safe braking for vanishing vehicles in front of you and 110km h of static fake cars at night. Compared with the data released by other car companies, the AEB brake stop of 130KMH for static fake cars during the day is a new record. Because like some car companies that are good at intelligent driving assistance, they can only achieve AEB braking of 100km h or 110km h. In this way, BYD is not only not weak in this regard, but also has certain advantages. In fact, the so-called AEB is the automatic emergency braking system of the vehicle, including collision warning and automatic emergency braking. Traditionally, AEB is an active safety device, but in the era of new energy vehicles, it can also be placed in the intelligent driving assistance part. Or take BYD as an example, many of its models are using the first computing platform and domain controller collaborative architecture, AEB is no longer a separate logic, but will call more information collection capabilities of intelligent driving sensors and the computing power of the first computing platform to make regulatory control and output final decisions. Previously, in the static fake car test of the ACC of the car emperor, BYD's Yangwang U8 and Denza N7 both entered the top four, which can also confirm BYD's intelligent driving ability to a certain extent. Of course, we have also talked about it before, ACC braking and AEB braking logic is still very different, ACC braking is a more calm braking in the process of adaptive cruise, and AEB is more like the last line of defense, driving or cruising in the process of sudden braking in the face of an imminent collision, the test of perception, decision-making and execution ability is also greater.
The daytime AEB is mainly a test of the accuracy and distance of perception for static false car braking. Daytime AEB brakes on disappearing vehicles or ghost probes are a test of perception, decision-making and speed of execution. The nighttime test is more of a test of the stability of perception, and there will still be a big difference in the difficulty coefficient between daytime perception and nighttime perception.
At present, many new energy vehicles have AEB function, but it is not easy to achieve higher speed braking and higher stability. Objectively speaking, a big difficulty in doing AEB at present is to prevent false triggering, especially at high speeds. As a simple example, if the AEB makes a mistake in making a decision and causes the AEB to activate an emergency brake, the danger is unimaginable. It can be said that AEB mistouch is more harmful than missed detection. In the process of high-speed driving, the shaking of the vehicle will be greater, which requires a more stable perception and regulation strategy, and on this basis, a large number of tests and verifications can be done to make a set of AEB systems that do not accidentally touch and rarely miss detection. Personally, I think BYD still has certain advantages in doing AEB. R&D capability is one aspect, and more importantly, BYD has a larger number of models on the road, which has more generalized scenario data support to train and optimize AEB. I think it is still very difficult for a car brand to make a good set of AEB if it does not have hundreds of thousands or millions of units in the market. In the end, judging from the current AEB test and the ACC brake test on the Internet, BYD has shown a relatively strong level, which can show its technology and potential in intelligence to a certain extent. However, it should also be emphasized that the AEB test of the U8 circulating on the Internet is only a test, and it remains to be seen how it will perform in the production model in the later stage. I don't know what everyone thinks of this test, can it be called an absolute strength to break the AEB record?
