The general recipe of the Seven Wounded Fists - the qi of the five elements adjusts the yin and yang, damages the heart and hurts the lungs, destroys the liver and intestines, hides the spirit and is frustrated, and the three Jiao Qi are rebellious and the soul is flying.
The Seven Wounded Fists are the unique divine skills of the Kun Gong Sect in the Book of the Dragon Slaughtering in the Heavens, and they are also the unique masters of the Kun Sect in the martial forest that no one knows and knows. From this general recipe, you can glimpse its incomparable power, which can make the opponent's heart and lungs hurt and scatter. It can be said that seven wounded fists come out, who fights with the front?
With the acceleration of electrification transformation, many emerging car companies have sprung up like mushrooms, and Auto Wulin is experiencing major changes unprecedented in a century. In this fiercely competitive arena, the participants practiced hard and showed their magic, hoping to break through the siege and dominate the martial arts.
Automatic driving is the "Seven Wounded Fists" in the car martial arts, the ultimate manifestation of car intelligence, and the sense of scientific and technological intelligence that is also illusory and true, which transforms the unmanned vehicle that was once "heavenly and night" into reality, which is enough to become the martial supreme who "commands the world, who dares not to follow".
As the representative of the "new car-making force", Xiaopeng Automobile (09868. HK, hereinafter referred to as Xiaopeng), successively won the "New Forces" 2021 annual sales crown and the first quarter of 2022 sales crown, becoming a veritable double champion.
Even if he is temporarily ahead, in order to achieve the ultimate goal of dominating the world in the future, Xiao Peng also needs to think of danger in peace and determine the direction of future cultivation.
He Xiaopeng, co-founder, chairman and CEO of Xiaopeng, has always stressed that Xiaopeng will insist on exploring intelligent driving, especially in the field of automatic driving. With the anchored policy, Xiao Peng concentrated on practicing the "Seven Wounded Fists".
However, because the initial "internal force" is still not skilled, the resulting accident was exposed to the newspaper, triggering fierce discussion among netizens.
In March, the owner of the Xiaopeng P7 in Yueyang, Hunan Province, rear-ended a stationary rollover vehicle in front of him while using automatic assisted driving.

The two parties involved have their own opinions, the owner said that after turning on the automatic assisted driving on the national highway for more than ten kilometers, he suddenly encountered a car that overturned on the road, at this time the automatic assisted driving did not have any alarm and deceleration, and the owner said that after he found the abnormality, the brake did not respond, and finally an impact accident occurred.
Xiaopeng said that in the process of using ACC + LCC (adaptive cruise control function + lane centering function), the owner did not maintain the observation of the environment in front of the vehicle and take over the vehicle in time. After the investigation and judgment of the local traffic police department, the conclusion is also in line with Xiaopeng's statement.
Combined with the statements of both sides, the following facts can be extracted:
1. The vehicle has been safely driving for more than ten kilometers on the national highway relying on automatic assisted driving.
2. The vehicle did not recognize a car that had rolled over suddenly appeared in the field of vision.
3. The early warning system of the vehicle has no prompts and does not automatically take braking measures.
4. The owner of the vehicle did not take over the vehicle in time. (The vehicle does not artificially slow down or turn the direction to avoid the phenomenon in advance).
Based on the above facts, the logic of the whole incident is very clear: the vehicle did not identify the obstacles on the road, so the system did not enter the early warning cycle, and the automatic obstacle avoidance and braking were not triggered, and the driver who was supposed to take over the vehicle did not intervene in time, resulting in tragedy.
The direct trigger for this incident is twofold: first, Xiaopeng's intelligent system did not recognize a stationary rollover car, and machine learning and model recognition (the artificial intelligence system may not have learned the appearance of a rollover car) were not perfect; second, in an emergency, the driver did not take over the vehicle in time.
Seemingly accidental events, there must be a necessary root cause, what is the volt line behind it? Let's just say, how can we learn our lessons and avoid similar things happening again?
01 Assisted driving, not autonomous driving
The power of the Seven Wounded Fists is well known, and the benefits of fully autonomous driving do not need to be repeated, but how is automatic driving defined before reaching the realm of pure fire? Park/port autonomous driving, assisted driving, automatic assisted driving and other terms are full of publicity and reporting, how to identify different levels of automatic driving, is the top priority.
Generally speaking, the L0-L5 level of autonomous driving that consumers often hear is based on the SAE (Society of Automotive Engineers, International Society of Automotive Engineers) autonomous driving classification in the United States, and the higher the standard value, the higher the quality index of automatic driving.
In order to standardize the domestic standards for automatic driving, the recommended national standard GB/T40429-2021 "Automobile Driving Automation Classification" proposed by the Ministry of Industry and Information Technology and centralized by the National Automobile Standardization Technical Committee was released in August 2021 and officially implemented from March 1, 2022.
The standard specifies the principles, grading elements and technical requirements framework to be followed in the classification of automotive driving automation, and divides the driving automation level into 0 to 5 levels, a total of 6 levels, based on the degree to which the driving automation system can perform dynamic driving tasks, as well as role assignment and operating range restrictions.

Level 0 driving automation (Emergency Assist) can sense the environment and provide useful information to assist drivers to avoid danger, and the usual functions include lane departure warning, forward collision warning, automatic emergency braking, lane departure suppression, etc.
Level 1 driving automation (Partial Driver Assistance) continuously performs lateral or longitudinal motion control under designed operating conditions, and typical functions include lane center control, adaptive cruise control, etc.
Level 2 driving automation (Combined Driver Assistance) continuously performs lateral and longitudinal motion control of the vehicle under designed operating conditions, and the usual functions include high-speed pilot assisted driving, parking lot memory parking, etc.
Driving automation at level 3 and above is only beginning to enter true automation, where the system can continuously perform vehicle lateral and longitudinal motion control and has the ability to detect and respond to targets and events.
So, what is the level of "automation" function of the Xiaopeng P7, the model involved in the accident? The author consulted the user manual of Xiaopeng P7, queried 25 subjects under the directory of driving assistance, and classified these 25 subjects according to the latest driving automation classification.
After the author sorted it out, only 11 of the 25 subjects meet the driving automation level, and all of them are in level 2 driving automation and below, which means that it is far from reaching the level of full automation.

The highest degree of automation is the three Level 2 driving automation functions, which, according to the grading standard, all three functions need to be realized under specific conditions, and require the driver to observe the surrounding environment and take over the driving rights of the vehicle at any time in a crisis.
Parking lot memory parking needs to be fixed and unchanged parking lot, and it needs to be based on the memory of the previous parking, so that the memory parking can be realized in the next "cat painting tiger".
Intelligent auxiliary lane change, under the premise of peripheral safety, after the driver's operation lane change instruction, the vehicle can realize its own lane change and keep the lane center and adaptive cruise function; high-speed navigation assistance can only be opened on a specific highway or urban expressway to achieve point-to-point navigation and automatic driving.
Obviously, the three most advanced functions have great limitations, that is, at this stage, assisted driving is only an auxiliary, and there is still a long way to go from true automatic driving.
02 "False" propaganda is rife
At last month's electric vehicle 100 people meeting, He Xiaopeng made a keynote speech on "The Era of Advanced Autonomous Driving Is Coming".
He Xiaopeng proudly said that the cumulative mileage of Xiaopeng intelligent driving has reached 140 million kilometers, and the auxiliary parking has achieved 7.34 million.
The user penetration rate of the XPILOT 3.0 system has reached a staggering 96.2%, while the mileage penetration rate of high-speed NGP (NavigationGuided Pilot) has reached 62%, that is, 62 kilometers per 100 kilometers are driven by NGP intelligent automatic driving.
In this regard, Xiaopeng is very confident that it can be two to three years ahead of most companies in the field of assisted driving.
Not only that, Xiaopeng hopes that assisted driving can be from several cities to more cities, from some scenes to larger scenes, or even all scenes, to the first-class highways, secondary highways, tertiary highways, and even roads in smaller communities from highways to cities.
"Divine Skills" have achieved a small success, and they must be hyped up to enhance their prestige in the martial arts.
The intelligent promotional page of Xiaopeng P7 is full of various driver assistance function introductions and video demonstration links, these cool demonstrations, it is easy to attract consumer attention.
Only by clicking on the tiny instruction button in the upper right corner will the last sentence in the explanation column prompt the consumer: assisted driving is not effective in any scenario, and human intervention must be carried out in time if necessary.

Objectively speaking, xiaopeng's auxiliary driving function introduction in the introduction of the wording is more attention, has not been half a step beyond the thunder pool, has always emphasized the word "assist". However, the friends who are also "new forces" are much bolder.
The word "automatic" appears frequently in Nio (09866. HK), Ideal (02015. HK) and Tesla (TSLA.O) brochures, if you don't carefully screen, you really think that the fully automatic that you once fantasized about has been fully realized.
The intelligent arms race between "new forces" can easily make consumers assimilate them, and the preconceived "automated" impression also lays hidden dangers for future dangers.

Overly aggressive "false" propaganda is an important factor in misleading consumers into letting down their vigilance and precautions.
03 Visible safety, invisible danger
Although the Seven Wounded Fists were fierce, the road to divine cultivation was not smooth. When the internal strength is insufficient, each time you practice one layer deeper, the power is one layer greater, but the damage is also added to the next layer.
The key advantage of autonomous driving or assisted driving is safety.
He Xiaopeng said that by comparing the two data on the use of intelligent assisted driving and traditional manual driving on high speeds, the safety factor of intelligent assisted driving has increased by more than 10 times, and it is hoped that it will be 100 times in the future.
It is true that the author once drove the Xiaopeng P7 to experience assisted driving, and it is indeed possible to achieve regional staged assisted driving on some high-speed and urban expressways, and the experience is very good.
Common operations such as following cars, changing lanes, overtaking, turning, and entering and exiting ramps are basically achievable, and the frequency of these conventional road conditions is more than 90%. As everyone knows, it is precisely because the assisted driving experience is good in most scenarios, causing the driver to relax his vigilance, but it is more likely to lead to more serious dangerous accidents.
On April 11, 2022, an Ideal ONE with assisted driving on the S12 Shenjiahu Expressway rushed into the traffic control area and collided with multiple warning facilities, resulting in serious damage to the vehicle.
Fortunately, the front of the vehicle was only damaged, and the people inside the vehicle were not injured. The cause of the accident is that assisted driving causes the driver to let down his vigilance and become distracted without noticing the danger.
In August 2021, a well-known investor drove the WEILAI ES8 in a traffic accident, according to media reports, after the driver activated the pilot assistance function, he crashed into a road construction vehicle in the Hanjiang section of the Shenhai Expressway and unfortunately passed away.
It can be seen that not only the Xiaopeng P7 has an assisted driving accident, but also Weilai and Ideal are also caught in it. It should be noted that the assistant driving level of "Wei Xiaoli" is below level 2 (including level 2).
Trusting assisted driving too much is one step closer to danger.
Perhaps many driver friends have not experienced the assisted driving function of the "new force", so it may be easier to understand how intelligence and danger depend on each other.
Cruise control has become popular on fuel vehicles in the mid-range and above.
On highways with low traffic, it is possible to start a cruise control that can maintain a constant speed and release the driver's right foot for continuous work.
However, if the duration of the cruise is too long, the risk factor will gradually increase: because it does not need to be operated for a long time, the driver is prone to mental relaxation and inattention.
Most importantly, when there is a sudden emergency, the foot is not on the accelerator or brake, do not underestimate this problem, it may cause the response is not timely, or it may cause the sudden lift of the foot and can not distinguish between the brakes or the throttle. It was technology that led to security, but in fact it brought danger.
In the case of safe observation, in the case that the driver can take over at any time, the auxiliary driving is basically positive, and all auxiliary functions appear as additional functions. But it is precisely because of trust that the preconditions for security observation and takeover at any time are ignored, and the impact of negative effects is getting bigger and bigger.
Only those with great internal strength can practice the Seven Wounded Fists, otherwise the cultivators are likely to go into the fire and devour their bodies.
04 How far is autonomous driving?
At this stage, there are still many technical problems in the high-level assisted driving of bicycle intelligent orientation, for example, on the road of medium and high speed driving, the perception system still has a relatively large probability of failure in the recognition of stationary objects.
For example, other vehicles entering the main road from the ramp parallel line are difficult to be accurately detected by assisted vehicles; or the recognition accuracy of unconventional manual control is too low.
The upgrade of the hardware and software assistance system will certainly gradually solve the current problem, but as long as the automation level is still at level 2, which means that the driver must continue to maintain the concentration of attention and the readiness to take over at any time, then the actual contribution of assisted driving is not as large as imagined.
Perhaps only the realization of level 4 driving automation will truly enter the automotive automation revolution.
The automotive automation revolution is naturally a long process, subject to the common progress and promotion of all links, and cannot be achieved overnight. Prior to this, the "new forces" still practiced their internal skills more, did not rush to achieve success, and encouraged them to grow seedlings, otherwise they would eventually harm others and themselves and lose their trust in the rivers and lakes.
