In January 2021, WITH a price of 448,000-526,000 yuan, WEILAI ET7 quickly sucked up a wave of powder, after all, at that time, there were not many pure electric medium and large cars on the market.
As the brand's flagship pure electric sedan, the first model of the NT2.0 platform, it directly points competitors to the 7 series, 150kWh solid-state battery pack, endurance of more than 1000 kilometers, wind resistance coefficient of 0.208 is the top level, equipped with vehicle-grade lidar, can achieve a higher level of auxiliary driving capabilities, and all this is now getting closer and closer to us.
On March 28, Weilai ET7 was finally delivered, and the lidar on the roof is a major feature of the appearance of the new car, some people think that science fiction, some people say ugly, Whatever, this thing is really fragrant, it is really different, and it is not a look of goods, more practical, which is called by experts, "an important medium across L2 to L3".
As we all know, there are many levels of automatic driving L2, 3, 4, 5, of which most of the current vehicles can do L2 level, mainly relying on millimeter wave radar and high-definition cameras, but millimeter wave radar for the front of the completely stationary state, or two in the same direction and the same speed state of the relatively stationary object, there is a certain chance that it can not be identified, this drawback is also doomed, it is difficult to make progress in the field of automatic driving. So everyone immediately replaced the protagonist with lidar, which has a wider detection range and higher accuracy, which can make up for the drawbacks of millimeter-wave radar and the inability to accurately model surrounding obstacles.
It should be noted that although the NIO ET7 delivered now has lidar, it has not yet "awakened", resulting in some functions that cannot be fully released.
According to the Weilai sales staff: "Although the Weilai ET7 is equipped with lidar, there is no new breakthrough in functionality, for consumers, they can only continue to use basic adaptive cruise and other functions, as for the opening time of the new features, the official has not yet made it clear." ”
In this regard, Xiaobian is also the first time, contacted the official personnel of Weilai Automobile, which said: "At present, Weilai ET7 is the only mass production model equipped with lidar in the family, compared to the previous products, it is undoubtedly more outstanding in terms of driving assistance functions, the detection distance is farther, even pedestrians under the shade can be accurately identified, in the middle of this year we will launch NOP PLUS, and the new features of NAD will be launched at the end of the year." ”
In fact, since Weilai Automobile released lidar last year, Xiaopeng and Weima have "followed suit", and independent car companies such as SAIC Zhiji and Great Wall Salon have also launched offensives, quickly pulling up a wave of lidar boom.
The reason why car companies will do this is inseparable from the excellent accuracy of lidar. According to the ElecFans research report, the safety of the automatic driving system equipped with lidar can reach 99.99%, while sensors such as cameras and millimeter-wave radar can only guarantee 99%.
On the other hand, because of the gradual liberalization of the policy, according to the "Interim Regulations on the Management of Automotive Radar Radio" previously issued by the Ministry of Industry and Information Technology, which clearly delineates the main use scenarios of automotive radar, and plans the 76-79GHz frequency band for automotive radar, the main use scenarios include adaptive cruise control, collision avoidance, blind spot detection, lane change assistance, parking assistance, rear vehicle warning, pedestrian detection, etc., and implemented from March 1.
If it is said that the first wave of offensives of new car-making forces competes with each other, then the second wave is undoubtedly an intelligent cockpit system, and this third wave is the auxiliary driving function in front of it, who is more advanced in technology, who can get the market opportunity.
In the eyes of car companies, the number may be a strong proof of their strength, since The launch of a single lidar in Weilai ET7, the back wave is higher than one, the Zhiji L7 is equipped with two, the Weima M7 directly dried to three, and the mechanical dragon directly broke through the sky and became the world's first model with four lidars.
For WEILAI ET7, although some functions have not yet been fully opened, with the blessing of lidar, it can undoubtedly be more accurate when using existing functions. When NOP PLUS is officially launched, when the new features of NAD are gradually opened, this car will also really exhibit 100% of its strength, and see how consumers react when they pick up the car, perhaps it really confirms the old saying that good food is not afraid of late.
