As we all know, winter has always been the enemy of new energy vehicles, because the "electrified" part of the car will be more or less affected by low temperature, such as sensors or cameras, low temperature and light and other factors will lead to inaccurate identification of sensors or cameras so that there is a deviation from intelligent assisted driving, and these factors are also the decision points that everyone (especially northern friends) pays more attention to when buying new energy vehicles.
Understand the winter test of the car emperor).
In fact, for consumers who want to buy a new energy vehicle, this is an extremely asymmetric information black hole, because it is impossible for 4 sons to give you a test drive for a winter, and then let you decide whether to buy the opportunity, at the same time, the model is also constantly iteratively updated, last year's vehicle information may not be suitable this year, so the platform is very useful for the new energy vehicles of the year to do a horizontal evaluation.
For example, this time the 2023 winter test activity of the car emperor in Mohe is very representative, and one of the results of the "night snow ACC battle" has refreshed everyone's knowledge reserves, because no one expected BYD's intelligent counterattack and became the biggest winner, because in the "night snow ACC static fake car test", "night backlight ACC static fake car recognition test", "night backlight snow ACC static fake car recognition test", his Denza N7 (**configuration|inquiry), look up u8 (**configuration|Inquiry) broke through three levels in a row, and in the final victory of the 4 seats, the BYD Legion occupied 2 seats, so how did it do it?
Excellent hardware foundation
Let's start with the first level, the "Night Snow ACC Static Fake Car Test", as the name suggests, is to place a static fake car in the middle of the road, and the vehicle turns on the adaptive cruise system and automatic emergency braking function to see if the vehicle can complete the braking. This is the most basic level of testing the basic software and hardware level of the vehicle.
Judging from the results, only 17 of the 51 cars tested, including Wenjie M5, M7, AVATR 11, Ideal L7, L9, Xiaopeng G6, Haobo GT and other independent models have passed the test, while BMW i3, VOYAH FREE, Wei brand Gaoshan, Mercedes-Benz EQE, Toyota BZ3 and other models have been passed at the first level. The pass rate is only one-third.
Uninterrupted power to the north).
From the above table, it is not difficult to see that most of the people who can pass the first pass are equipped with lidar, take Denza N7 as an example, after the optional high-end driving assistance system worth 23000 yuan, the hardware of this system uses a single computing power of 254TOPSNVIDIAORIN chip, and will also add 2 LiDAR arranged under the headlight group Suteng Juchuang M1, and the front-looking monocular camera will also be replaced with an 8 million pixel binocular camera, and the overall number of hardware for assisted driving will reach 33。 Therefore, from the hardware level, the Denza N7 and Yangwang U8 have already beaten a number of car companies that usually boast of "autonomous driving", which can also be intuitively demonstrated from the actual test results.
Strong software adaptation
Coming to the second level, it is based on the first level plus the backlight factor, the difficulty is upgraded, from the results of the remaining 17 cars, there is only 50% pass rate, Baojun Yueye, Haobo GT, Mengshi 917 and other models, and even the Model Y, which is very strong in intelligent driving, has fallen in the second level.
Uninterrupted power to the north).
From the above table, we can also see that it is not enough to be equipped with lidar, some brands still lose in software adaptation, and we can also look up to the U8 recognition distance of up to 100 meters to see the awesome of BYD engineers, of course, this is also inseparable from the nvidia drive orin intelligent driving processor it carries, and the actual effect is indeed far away from other homes in addition to hard power, soft power distance.
Good combination of hard and soft
To the third level, the difficulty of passing is even greater, for the "night backlight snow acc static fake car recognition test", that is, night + backlight + snow, we watched**, the scene is almost impossible to see the road conditions with the naked eye, and the test speed has also dropped to 40km h, which is more than twice as difficult.
In the end, only four cars passed, namely Yangwang U8, Denza N7, NIO ET7, and AVATR 11, and among these four cars, Denza N7 and Yangwang U8, two BYD series models, were both in the list, becoming the biggest winners.
It is worth mentioning that the performance of Yangwang U8 and Denza N7 in these three levels has been very stable. Especially looking up at the U8, in the first level, it was recognized and braked when it was far away from the fake car, and finally it stopped about 12 meters away from the fake car, ahead of other models.
From the above table through the models we can also see, a single hardware or a single software imposed in the case of snow will cause strong interference to the vehicle camera recognition, the test is a more comprehensive quality embodiment, that is to say, there needs to be a corresponding body stability system to keep up with it in order to make it brake, and BYD's Yun Yuan system I think it is in this regard that has made a lot of efforts, so that Denza N7 and Yangwang U8 have achieved the final success.
Conclusion:
In the end, actually, I was rightThe performance of the winter test is amazingThe result is not surprising, because it happens to be in the automotive industry, and BYD's evolution in recent years is obvious to all. In the past few years, there are also some manufacturers who advocate their own intelligent driving, saying that "intelligent driving" is not equal to ACC, in fact, even ACC is not good, and it is still a smart fart
Especially the bosses who have been doing parallel import oil trucks for decades around me, have replaced their big Range Rover with looking up to U8 during this time, and now the first job of college students has broken through and wanted to enter BYD, I am even more determined that the current BYD Denza and Yangwang can really be bought with their eyes closed, what do you think?
