Introduction: The combination of cameras+millimeter wave radar is like the eyes of frogs. It is okay to judge dynamic objects, and it is almost incompetent for non -standard static objects.

The smart cars of the new power car companies have a traffic accident again.

On August 11, a screenshot of WeChat chat records showed that in the state of opening the driving auxiliary system, a Xiaopeng P7 hit a faulty vehicle ahead at a speed of 80km/h and caused a fault that was dealing with vehicle failure. The personnel were hit.

Regarding the news, Xiaopeng Automobile told the First Financial reporter: "After verification, on the afternoon of August 10, a owner of Ningbo drove the vehicle with a collision of the vehicle failure person in front. The victims who died were sad and regrettable. At present, the traffic police department has already filed a case, and the store has already gone to the site to assist in handling. We will fully cooperate with relevant departments to conduct an accident investigation, continue to follow up the follow -up results, and assist customers to handle follow -up related matters ","

According to online chat records, the owner did not use Xiaopeng's high -speed NGP system, set up a cruise speed of 80km/h, and opened the LCC lane center function. However, the system did not identify the fault car and people in front of the system, and the owner said that he was "distracted."

The identification of static objects and alien objects is a huge problem that needs to be faced by millimeter wave radar and visual perception solutions. Earlier, Tesla Autopilot Driving Auxiliary with a millimeter wave radar and visual perception scheme has repeatedly hit the static objects; in addition, the driving assistance system of car companies such as Xiaopeng, ideal, Weilai and other car companies has occurred. Or a car accident caused by alien vehicles.

The ideal car founder, chairman, and CEO Li Xiang once said: "The current combination of cameras+millimeter wave radar is like the eyes of frogs. It is okay to judge dynamic objects, and it is almost incompetent for non -standard static objects."

An engineer of a self -driving company told reporters that Xiaopeng P7 adopted a fusion perception solution for visual and millimeter wave radar, which is also a perception solution used by most car companies. Among them, millimeter waves are mainly used to detect obstacles through radio waves, but it is difficult to accurately identify the types of obstacles. Static objects such as routes, dragon gates, and guardrails will be identified as obstacles. In order to ensure the smoothness of the driving assistance system, the algorithm The top is usually ignored the radar waves that are not moving on the road. The visual needs to rely on a large amount of sample volume to learn, and the identification effect of alien objects is poor. This time, a person stands before the crashing vehicle, and the vision may have identification problems.

"In addition, in this accident, AEB's active braking is also difficult to play. At present, most of the products on the market AEB take effect is less than 70km/h." The ability to identify vehicles will be more stepped, and the recognition ability of static objects will be greatly improved.

On the other hand, although the current intelligent driving assistance system has almost become the standard of the new car, it may be misled by car companies or due to early adopters, and many users use the intelligent driving assistance system as a autonomous driving system. reason. At present, car companies still need to help correctly understand the corresponding system and popularize the correct habits.

Taking Xiaopeng Automobile as an example, before the owner uses the corresponding driving assistance system for the first time, Xiaopeng Automobile's operating interface has a mandatory test answer link to help users understand the use scenario that the driving assistance system cannot take effect; The apps of the owner push the learning and Q & A content on the Nio Pilot function for the owner.

Cui Dongshu, Secretary -General of the Federation, said that in addition to rational promotion of autonomous driving, car companies must also explain the functions of driving assistance in detail. When the driving assistance function has identified errors, consumers should be given in time.
