At present, all the assisted driving systems, no matter how perfect the "bragging" of the marketing level of car companies, there are still many "weak scenarios" that cannot be identified and handled.
Just this week, a video of an assisted driving accident successfully pushed Xiaopeng Automobile to the Top of Weibo's hot search, and once again triggered a fierce discussion among everyone.
Regarding the accident itself, after specific understanding, it was learned that a car owner of The P7 in Yueyang, Hunan Province, turned on his so-called "automatic driving" on the national highway for tens of kilometers, and a rolled over vehicle suddenly appeared in front of the road.
However, the Xiaopeng P7 he was driving did not issue any alarm and deceleration, and directly crashed into it.
At the same time, according to the driving recorder provided by the owner, the acceleration value before the impact has increased. And he claimed to have more than 7 years of driving experience, and he also stepped on the brake pedal at the time of the incident, but the vehicle did not slow down. And until now, looking back on the scene at that time, I still have occasional nightmares.
In this regard, Xiaopeng Automobile after-sales experience commissioner said, "Automatic assisted driving on the identification of stationary objects, there is a greater difficulty, this in the vehicle manual also has an improvement, Xiaopeng is willing to send a year of extended warranty." ”
Subsequently, it was rejected by the owner of the car.
Soon, Xiaopeng officials also issued a statement: Regarding the accident reflected by the owner of the car, Mr. Deng, when using ACC+LCC (adaptive cruise control & lane centering function), it collided with the accident vehicle parked in front of it, and our company attached great importance to it. He deeply regretted the accident of the vehicle and expressed concern about Mr. Deng's physical condition.
After investigation, on March 13, the owner of the car, Mr. Deng, drove the Xiaopeng P7 in a local highway section and collided with the overturned vehicle parked in front of him, and the accident did not cause injury.
After the accident, through the background collision monitoring, our customer service staff called the customer for the first time to inquire about the situation and give assistance and guidance.
The preliminary judgment is that the owner did not maintain the observation of the environment in front of the vehicle and take over the vehicle in time during the process of making the ACC + LCC (Adaptive Cruise & Lane CenterIng Function).
After the investigation and judgment of the local traffic police department, the conclusion is also in line with the above situation.
At this point, the accident itself can be said to have come to an end. But looking deeper, from my personal perspective, is to talk about many of the things reflected behind it.
First of all, we need to know that according to the "Automobile Driving Automation Classification" previously issued by the Ministry of Industry and Information Technology of the Mainland, the current driving automation level is divided into 0-5 levels.
Most of the models currently on the market are maintained at Level 2 or below, so in the event of an accident, the standard stipulates that the driver is fully responsible.
At present, all the assisted driving systems, no matter how perfect the "bragging" of the marketing level of car companies, there are still many "weak scenarios" that cannot be identified and handled.
The stationary vehicles in front of this article, especially the "black" vehicles that rolled over, were very typical of the very small cases in the sunlight.
Previously, in a similar accident in Taiwan, Tesla had not identified a white rollover truck in front.
As for other scenarios, they also include: no lane lines, lane lines are not clear, lane lines are staggered; large curvature curves occur when the speed is fast; extreme weather conditions where it is difficult to see traffic sign characteristics.
Therefore, this puts forward certain requirements for the driver himself after the auxiliary driving function is turned on.
And it should be emphasized that the current auxiliary driving system is still in the "man-machine co-driving" stage. During use, although it can reduce the fatigue of the driver to a certain extent, it is still necessary to monitor all the time, and it is absolutely impossible to be inattentive, distracted or even diverted. When encountering complex scenarios that the system cannot handle or there are security risks, it is necessary to take over manually in advance.
In fact, as early as the warm-up stage of Xiaopeng's launch of the NGP high-speed pilot assistance function, its official emphasis has been emphasized more than once: "It still belongs to the category of assisted driving." ”
In other words, NGP can not be arbitrarily considered to be fully automated driving, NGP can not identify all blind spots, the driver should hold the steering wheel throughout the whole process, observe the road conditions, timely judgment, when special circumstances occur, the driver should brake in time, take over the vehicle driving.
At the same time, in the NGP security exam pushed by Xiaopeng for users, similar to the scenes mentioned at the beginning of this article, there are also key records.
All kinds of measures are hoped that users will have a clearer understanding of their auxiliary driving systems, understand where the "boundary" is, what can be done, and what cannot be done.
However, from the current real situation, there will still be many accidents that are "mistaken".
So next, how to more perfect the effective education of consumers, so that they for the current assisted driving system, and even later will introduce more advanced functions to form a more perfect understanding, is the task in front of all OEMs.
Finally, of course, I hope that everyone can feel the convenience brought by scientific and technological progress in the correct operation.
