Recently, the content of the AEB test has become a hot topic of continuous discussion in the car circle, and major car companies have joined the group chat to express their views. What is AEB?Its full name in English is: Autonomous Emergency Braking, which translates to automatic emergency braking system, its role and value is to issue early warnings or take different degrees of braking when it comes to the crisis of traffic participants, or even complete braking, so as to reduce or avoid accidents, to put it bluntly, AEB can not only save itself, but also save people.
For friends who are concerned about automobile safety, AEB is not an unfamiliar content, because in 2021, the China Automotive Center launched the "Performance Requirements and Test Methods for Automatic Emergency Braking System (AEBS) for Passenger Cars", which was officially implemented in October of the same year, putting forward higher requirements for car companies. Since then, many car companies have invariably added AEB configurations to their vehicles in order to obtain better C-NCAP results, and of course, problems have also occurred. After the difference between what is there and what is not eliminated, what is effective and what is not effective, and what conditions can be used to achieve the effect, becomes another major difference between the brand and the model.
That is to say, the effect of most brands of AEB requires certain restrictions, for example, at a speed of 60km h, the brake of the car to the car can be realized, and for pedestrians and bicycles in motion, the effective speed of the AEB will be reduced to a certain extent, even if the car companies that have made certain achievements in the field of intelligent driving technology, they will also control the speed requirements at 80km h. When the speed is increased to 100km h, whether it is the perception ability, the ability to control, or the chassis braking ability has put forward higher requirements, at the same time, the effect of the entire AEB is realized, but also needs the cooperation of the surrounding environment, it can be said that the starting mechanism of the whole system is completely out of the daily driving habits of ordinary people, which is very chicken. As a result, the majority of car enthusiasts call on car companies to be more sophisticated in AEB design, so that the sense of experience and practicality can be improved.
Recently, a BYD looked up to the U8's AEB test on the network, showing a more valuable AEB role. The whole section** is divided into two driving environments, day and night, of which the daytime part is two sets of tests, one is 110kmh speed against the disappearing front car, the other is 130kmh speed to the stationary front car, and the night part is 110km H speed reaction to the stationary front car, under the three tests, Yangwang U8 has achieved the expected braking effect, not only to maintain a certain safety distance from the test vehicle, at the same time, after braking, Yangwang U8 body condition is also maintained in good condition, with absolute strength to break the AEB record.
According to relevant sources, the reason why Yangwang U8 can achieve efficient and accurate response of AEB in multiple scenarios is mainly due to the application of Yi Sifang, Yun Yuan and other technologies, so that the power and chassis can form millisecond-level collaborative control, which not only effectively improves safety, but also ensures the driving comfort after AEB triggering as much as possible.
In addition, BYD has also maintained rapid updates in other areas of intelligent driving technology, in July this year, BYD released the "Eye of the Gods" high-level intelligent driving assistance system, relying on the fully self-developed control architecture, the first distributed layout of the control algorithm, compared with the single and decentralized decision-making in each domain, it can achieve precise control of the best decision-making, and provide more systematic safe driving solutions for vehicles. High-speed obstacle avoidance and other scenarios.
Cars from manual driving to intelligent driving, there is still a long way to go, but it is very gratifying that we are witnessing this rapid transformation, taking "automatic parking" as an example, from the initial virtual function, to a few years ago can be independently detected, no need for parking space landmark line requirements, and then to BYD "Eye of the Gods" under the application of 100% autonomous parking of vehicles, we have seen the application of intelligent technology in daily driving step by step.
Chernyshevsky said: "All the problems that are debated and unresolved in theory are completely solved by the practice of real life. BYD seems to have provided an answer to this AEB battle by looking up to the U8 test.
