Preface
The door to the era of intelligent driving has been opened! In the wave of this technological revolution, the two camps of visual intelligent driving and lidar are fighting wits and courage. Who will become the "leader of the martial arts alliance" in the future? What kind of earth-shattering black technology will it bring us?
Today, we will take a look at it and take the lead in decrypting the latest intelligent driving solutions of domestic giants such as Huawei and DJI. Don't doubt it, this battle of science and technology will be several times more fierce than you think! Let's wait and see, the outcome of this conflict will completely change the pattern of the automobile industry!
1. Huawei Zhijie S7 model and visual intelligent driving technology were released
On April 11, Huawei's HarmonyOS Ecosystem Spring Communication Conference was held in a warm and exciting atmosphere. Huawei, as a domestic technology giant, will make a big splash in the field of intelligent driving.
In the center of the venue, a brand-new Zhijie S7 model was dazzling and attracted the attention of the audience. This first sedan in cooperation with Chery was unveiled again after half a year, but it brought us a new shock!
The Zhijie S7 covers the mid-to-high-end price range of 249,800 yuan to 349,800 yuan, and the highest version is equipped with a large 100kWh battery pack, and the power consumption data is desirable. But the most anticipated thing is the visual intelligent driving black technology that this model is equipped with for the first time!
At the scene, Yu Chengdong proudly introduced this epoch-making innovation. It turns out that Zhijie S7 does not use a conventional lidar scheme, but is composed of 3 millimeter-wave radars, 10 high-definition cameras and 12 ultrasonic radars"Visual Intelligent Driving Array。
This black technology, named HUAWEI ADS Basic Edition, can achieve true intelligent assisted driving on national highways and urban expressways. Lane change overtaking, road condition recognition, automatic parking... You know all of this so well that you can easily cope with road construction and cone diversions!
What's even more shocking is that Huawei's visual intelligent driving coverage rate is as high as 99.5% and the ramp pass rate is 96% in the actual measurement of the Shanghai elevated road, which is better than Tesla's 79% and 68.75%. Even smart parking is completely suppressed by Huawei.
In this regard, Yu Chengdong could not hide his excitement, and bluntly said that the performance of this visual intelligent driving has completely surpassed the "grandfather" Tesla. There was a round of applause at the venue, and the atmosphere reached the climax!
2. Analysis of HUAWEI ADS Basic Edition
At the scene, when Yu Chengdong mentioned the visual intelligent driving solution equipped with Zhijie S7, the scene immediately fell into a boil!
First of all, from the outside, this set of visual intelligent driving system, named HUAWEI ADS basic version, is not too outstanding. 3 millimeter-wave radars, 10 high-definition cameras, and 12 ultrasonic radars make up its "eyes".
However, it is these ordinary "eyes" that make it have unimaginable vision, and it does not need to rely on traditional lidar at all! Yu Chengdong explained complacently that lidar is expensive and will be replaced by this vision solution in the future.
With that, he began to show us the extraordinary capabilities of this set of black technologies one by one. The fusion of multiple sensors gives it a 360° field of view without dead angles, and it is clear beyond the direct viewing distance. Whether it's the night, the rainstorm, or the debris on the road, it's all at a glance!
Most importantly, with Huawei's powerful computing power and algorithms, HUAWEI ADS Basic can help you automatically change lanes, navigate, and avoid obstacles on highways. This kind of assisted driving experience is even inferior to Tesla!
Yu Chengdong said earnestly: "In the test of the Shanghai Elevated Road, the coverage rate of our visual intelligent driving solution was as high as 99.5%, and the ramp pass rate was 96%, while Tesla's data was only 79% and 68.75%. "
What's even more surprising is that the "brain" of this vision system is powerful enough to autonomously recognize road conditions on urban expressways and navigate around cones roadblocks! This is not just assisted driving, but a big step towards true autonomous driving.
Of course, the autonomy of the basic version of HUAWEI ADS is still limited. However, judging from Huawei's superb algorithm and chip technology, it seems that it is only a matter of time before real "unmanned driving" is realized in the future...
3. Compare Tesla's EAP driver assistance system
Just at the Huawei HarmonyOS Ecosystem Conference, the high-profile Zhijie S7 visual intelligent driving technology and Tesla's EAP had a direct showdown, and the results were breathtaking!
No one would have imagined that in the actual measurement comparison of the Shanghai elevated road, the performance of Huawei's visual intelligent driving system is far stronger than Tesla. Its 99.5% coverage rate directly leaves Tesla's 79% data far behind; The ramp pass rate of 96% is also nearly 1.5 times that of the opponent's 68.75%!
What's even more frightening is that during the entire test process, Huawei's visual intelligent driving has never been downgraded once, while Tesla's as many as 14 times. One can imagine how bad the driving experience of the latter is.
But the most staggering is yet to come. It turns out that Huawei's visual intelligent driving has the ability to identify obstacles such as water horse cones and barrels, and this is completely invisible to Tesla! A seemingly ordinary urban road may be a "stumbling block" for Musk's "star product".
In this regard, there was an uproar at the scene from time to time. After all, no one expected that China's dark horse companies have caught up with or even surpassed international giants in the field of intelligent driving.
Next, the contest between the two sides shifted to the smart parking scenario. Soon, the results were even more unexpected than everyone expected.
It turns out that Tesla's smart parking function cannot adapt to special-shaped parking spaces, oblique parking spaces, and even artificially defined custom parking spaces will be confusing.
In contrast, Huawei's visual intelligent driving is comfortable in various complex scenes, completing gorgeous parking actions one after another, winning applause from the audience.
Some people joked that if Musk was at the scene at the moment, he would have jumped up in fright. Because this is a blow to his EAP system!
In fact, this also proves Huawei's excellent strength in vision algorithms and chip computing power. The visual intelligent driving technology built on this is naturally easy to use.
In this regard, Huawei engineers explained that EAP is only a simple assisted driving system, and what they have launched is a real "visual AI driving". The latter has stronger environmental awareness and decision-making capabilities, and will surely shine in the field of autonomous driving in the future.
At the scene, people's enthusiasm was completely ignited. What kind of potential can visual intelligence drive exert, and what kind of surprises will it bring us? Everyone is deeply attracted by these unsolved mysteries...
Fourth, the high-end version of the Zhijie S7 equipped with lidar
After watching the "contest" between Huawei's visual intelligent driving and Tesla, are you still unsatisfied? Don't worry, Huawei's "trump card" has not yet been unveiled!
It turns out that in addition to the basic version of visual intelligent driving, Huawei has also tailored a set of "enhanced version" for Zhijie S7 - an intelligent driving system equipped with lidar!
You read that right, it is the award-winning "black technology" in the field of autonomous driving! Once blessed, the driving ability of the Zhijie S7 will soar to another level.
First of all, the forward-facing active safety performance will be greatly enhanced. The LiDAR has a long field of view, so that the forward AEB has an effective range of up to 4-150km/h, and the maximum braking speed reaches an amazing level of 120km/h!
With this "invincible" power, even if you encounter an emergency, you can respond as soon as possible and deal with it calmly. It can be called the "ultimate guarantee" of driving safety!
And lateral and backward security is not fiction. Compared with the ordinary version, the effective range of lateral active safety has been increased to 40-130km/h, and obstacles such as water barriers and cones can be actively identified, so as to truly achieve "no blind spots".
What's even more surprising is that after being equipped with lidar, Zhijie S7 has a terrifying road coverage of 99.56%! Whether it is a major urban arterial road, a branch road, or even many small roads and alleys, you can do whatever you want!
With such a "super vision", you don't have to worry about emergencies when you drive on the road. After all, this intelligent driving system is more "old" than you and me.
In the face of Huawei's "ultimate killer feature", I believe many people can't hold back the frenzy in their hearts. Is there anything more powerful and incredible?
In the future era of intelligent driving, what kind of "unique skills" will Huawei show?
5. The trend of visual intelligent driving replacing lidar
When talking about Huawei's intelligent driving solution S7, we can't help but be attracted by the two technical routes of "visual intelligent driving" and "lidar". Which of the two is better or worse, and which will be higher or lower?
If you think that visual intelligence is just a temporary expedient measure, you are very wrong! In fact, this technology has begun to set off quite a boom at home and abroad.
In addition to Huawei, domestic car companies such as DJI and Xpeng are also actively trying visual intelligent driving solutions. For example, with the "binocular vision sensor", DJI Automotive has implemented many L2+ autonomous driving functions on the Chery iCAR 03.
The most surprising thing is that the hardware cost of this vision solution is only less than 10,000 yuan, and some even only cost more than 5,000 yuan! You read that right, it is cheaper than an ordinary medium and long-range lidar!
For a while, people couldn't help but wonder: can visual intelligent driving really gain a foothold in the field of autonomous driving with a "flaw"?
"We use the deep integration of binocular stereo vision and computing algorithms to build a 3D environment model using 2D visual information, so as to achieve 'low-cost visual full coverage'. "
It can be said that it is precisely by relying on the continuous progress of algorithms and chip technology that visual intelligent driving can compete with the "rich and handsome" of lidar. In the future, it will continue to put enormous pressure on its opponents in terms of cost and performance.
However, lidar itself is also working to break through the cost bottleneck. It is reported that a manufacturer has launched a 3000 yuan lidar, which is nearly half of the previous drop. Over time, its price is set to fall even further.
It can be seen that visual intelligent driving and lidar are catching up with me on two different technical paths. Their "martial arts conference" is still indistinguishable, but it will undoubtedly bring us more and more surprises of intelligent driving!
epilogue
After today's decryption, I believe you have an in-depth understanding of the two major intelligent driving camps of visual intelligent driving and lidar. Their respective strengths are obvious to all, but they all have fatal shortcomings.
With its low hardware cost and powerful algorithm advantages from Huawei and other manufacturers, the visual intelligent driving solution is rapidly breaking through the bottleneck of cost and performance, and launching a fierce impact on LiDAR. However, the performance of traditional visual solutions in extreme environments such as night and bad weather is worrying.
In contrast, although LiDAR is expensive, it still has the upper hand in the reliability and safety of autonomous driving due to its excellent long-range detection capability and all-weather performance. However, it is also facing the serious challenge of rising supply costs.
However, what is certain is that the battle between visual intelligence and lidar is already on the line, and the winner is around the corner. The curtain of the era of intelligent driving is slowly opening, let us wait and see the final result of this summit showdown of science and technology!
