In today's Chinese new energy vehicle market, the NOA intelligent driving function is the focus of many manufacturers' publicity. The Great Wall, which has always been low-key, actually conducted a full-scene NOA live broadcast test by the chairman on April 15.
1. The chairman personally tested the intelligent driving without a picture, and the Great Wall live broadcast handed over the answer sheet
On April 15, Wei Jianjun, chairman of the Great Wall, started a live broadcast on the online platform, and he personally drove a Great Wall Wei brand Blue Mountain DHT-PHEV to demonstrate the NOA function in Baoding City.
NOA stands for Navigate on Autopilo, and the NOA developed by the Great Wall displayed by Wei Jianjun is known as the full-scene NOA, which can accurately identify traffic lights and various obstacles.
In the live broadcast, Wei Jianjun drove the Blue Mountain DHT-PHEV in the more complex urban area of Baoding. The NOA system accurately identifies the road at the complex "six crossings" and completes the left turn. Accurately identify sanitation workers, passers-by and other obstacles while driving, without any accidents.
In addition, during driving, this intelligent driving system will also take the initiative to complete actions such as giving way and changing lanes according to the situation. In short, in this live broadcast, Wei Jianjun did show the strength of Great Wall Motors in intelligent driving. But what are the advantages of the Great Wall's system in today's era of "intelligent driving involution"?
2. SEE large model, with safety as the first priority
Great Wall Motor's NOA system is based on the SEE intelligent driving model, and the name of this model is derived from the initials of the three English words "Safety", "Efficiency" and "Experienced".
It can be seen that the top level of the Great Wall headed by Wei Jianjun is probably the first requirement for this system. In this live broadcast, it can indeed be seen that this system responds quickly when giving way to passers-by and avoiding obstacles, and it is relatively smooth, without recklessness and stiffness.
Such a system will most likely not frighten pedestrians or car owners in actual driving. And this steady and conservative style also reflects Wei Jianjun's attitude towards intelligent driving.
At present, the top 15 cities of Great Wall Motors are expected to be the first to open NOA, which seems to be slower than other new forces. However, Wei Jianjun, chairman of Great Wall Motors, said in this live broadcast: "Users cannot be treated as guinea pigs, and users must be more assured to use." "Perhaps it is because of this original intention that the popularity of Great Wall Motors' no-figure NOA is slightly lagging behind.
3. Is LiDAR necessary for the hardware involution of the intelligent driving system?
The Wei brand Lanshan DHT-PHEV driven by Wei Jianjun this time should be a smart driving version equipped with lidar that will be launched in June. In addition to lidar, the car is expected to be equipped with 26 sensors, including cameras, millimeter-wave and ultrasonic radar.
As a leader in intelligent driving technology, Tesla President Elon Musk hates radar. On social platforms in the United States, he has said more than once that radar is a fool's technology, and he is even more scornful of the huge cost of lidar.
Therefore, Tesla's intelligent driving system adopts a pure vision solution, and the whole car is only equipped with cameras without any radar. However, the relatively simple road conditions in the United States with few passers-by can certainly achieve intelligent driving with only cameras. The road conditions in China's urban areas are extremely complex, with a large number of electric vehicles, pedestrians, and even cats and dogs all posing great challenges to the intelligent driving of purely visual solutions.
Millimeter-wave and ultrasonic radar can capture obstacles that cannot be seen by cameras, while lidar can realize digital twin simulation scenarios, thereby providing rich data resources to the cloud. In order to realize the "strong perception, safety, and fast iteration" of intelligent driving officially proposed by Great Wall Motors.
So in China, lidar is not a fool's technology, and it is not unnecessary to install dozens of sensors in the whole car. This is not only for the consideration of technological innovation, but also for the protection of the life safety of car owners and pedestrians.
