Qjie M7 caught fire after a rear-end accident, three people were killed, objectively analyze, what is the reason?

First of all, it must be emphasized that this was a regrettable traffic accident, and one child was among the victims. So, this is also a wake-up call for us again, driving on the road, safety first.

Secondly, after the incident, it quickly set off a heat on the Internet, and a number of topics related to M7 appeared on the hot search. Many people came out to express their opinions and opinions, and people with different opinions in the comment section also quarreled. Many of them lack objectivity, and even some are malicious and rhythmic, which is not a very good phenomenon. To put it mildly, it will affect everyone's impression of domestic new energy vehicles, and the result will be to hinder the development of new energy vehicles in China, because there has long been a very strange remark that electric vehicles are not as safe as fuel vehicles. Moreover, to put it mildly, a traffic accident has evolved into a big contradiction, which affects the internal unity of our family. Therefore, everyone should still maintain an objective and calm attitude, and not be used by certain forces as guns. Everyone should be able to understand this.

Then let's break it down.

In the video released by the party, we can see that, firstly, she questioned whether the maintenance vehicle occupies the fast lane, the maintenance vehicle is slow, and whether the maintenance vehicle has water, whether it has the ability to rescue and whether it explains the rescue, etc., and secondly, she questioned the AEB, GAEB function and battery of the M7.

Subsequently, the staff of Shanxi Yuncheng Expressway replied to reporters that at the time of the accident, the maintenance vehicle was carrying out mobile watering operations, and the maintenance vehicle was equipped with warning devices.

In addition, the official of the question world also gave a response, among which the key points are:

1、车辆为问界M7 Plus。

2. The speed of the vehicle at the time of the accident is 115km/h.

3. The airbag opens normally.

4. The battery is normal.

5. Cooperate with relevant departments to provide all necessary data.

6. Provide all possible support to family members.

At the same time, we can see several details in combination with the video footage taken by passing vehicles:

1. There is a fire in front of the vehicle, and there are traces of the fire extinguisher after spraying

2. The door cannot be opened

Then, through the above information, in fact, it is easy for us to sort out and analyze some content:

1. If the mechanical failure of the vehicle is put aside, such as brake failure, then the main cause of the accident may be the operation error, due to the relatively fast speed, the warning signal of the operating vehicle was not found in time, and when the operating vehicle with a slower speed was found, the brake or avoidance measures were not taken in time and effectively, and then the rear-end collision occurred, which was actually the root cause of the tragedy.

2. The M7 2024 model is divided into Plus version and intelligent driving Max version, among which, the intelligent driving Max version model is equipped with lidar and multiple cameras, supporting high-end intelligent driving assistance systems, high-speed and urban intelligent driving navigation and other functions. The car involved in the accident is the M7 Plus version, and it does not have the advertised omnidirectional active safety function.

At the same time, according to relevant media reports, this version of the M7 is equipped with two AEB solutions, including Bosch and Foretek. Among them, the working range of Bosch AEB is 4-85km/h, and 115km/h in the event of a collision is far beyond the trigger range, in other words, at this speed, the AEB system cannot take effect.

In addition, a so-called Bosch public statement was later leaked on the Internet, saying that the accident vehicle was not equipped with Bosch AEB. However, this statement is not stamped with an official seal, and the source cannot be found for the time being, which is very doubtful.

Because if it is really two sets of AEB schemes, how can we be sure that the car that had the accident was not equipped with its own scheme? Therefore, this picture may also be deliberately used by someone to confuse the public and add fuel to the fire.

In addition, whether the M7 uses the AEB solutions of the above two companies has not been confirmed by the relevant parties, which also needs to be noted.

3. The part of the fire is the engine compartment, not the battery at the bottom. According to the analysis of netizens, it may be that the impact caused the destruction of the oil pipeline, which in turn caused a fire.

4. The door cannot be opened.

This is also the most controversial point at the moment, because it gives the impression that if you can open the car door, you can save people.

Then we can see the relevant instructions for automatic unlocking in case of emergency in the owner's manual of the M7, the second of which reads that the vehicle has collided and the system receives a collision signal.

In other words, in the event of a collision-type accident, there is a prerequisite for automatic unlocking, and the system needs to receive a collision signal. The tips below are supplemented by the fact that the doors may not unlock automatically and that whether or not they unlock automatically is not based on the degree of damage to the vehicle.

Then the same is the analysis of the above netizen, he suspects that it is because the cutting position of the tail of the operation vehicle is high, and the sensor in front of the front of the car has not detected the corresponding signal, the power supply has been cut off, which has led to the door handle not popping open, that is, it has not been automatically unlocked.

In addition, in 2022, a similar situation occurred in the Lexus LM traffic accident, where the car door could not be opened after the impact. And in the instruction manual of the Lexus LM, it is also written: "If the vehicle suffers a strong impact, all doors are unlocked. However, depending on the force of the impact or the type of accident, the system may not work. ”

In other words, there are prerequisites for the realization of the automatic unlocking function of the car, and it is not 100% effective.

At the end of January 2024, the Ministry of Industry and Information Technology (MIIT) solicited public comments on four mandatory national standards, including the "Rear Collision Safety Requirements for Passenger Cars". The draft mentions that after a crash test, the door should be unlocked. No tools should be able to: For each row of seats (if there is a door), at least one door can be opened to allow occupants to enter and exit normally. If there is no door, move the seat or change the seat back position so that all occupants can evacuate.

As you can see, it is mentioned that the doors should be unlocked. "shall", on the other hand, is a principled provision or general requirement with a certain degree of flexibility that allows for exceptions and special circumstances.

At the same time, through the relevant provisions in the C-NCAP management rules (2024 edition), we can also see that the function of automatic door unlocking after a car collision is not a mandatory requirement. Of course, most cars today have this feature, otherwise you will lose your points in crash tests.

In short, through the above, I believe that some doubts can be broken, such as the rumors circulating on the Internet, what airbags are not opened, and the battery is on fire, in fact, they are all rumors.

As for the more important points, including what exactly was the cause of the impact, what was the cause of the fire, what was the cause of the three people's deaths, and other details, it is still necessary to go through a joint investigation by a number of relevant departments before a final authoritative conclusion can be reached.

But it is undeniable that crashing into the vehicle in front of you at a relatively fast speed while driving is the root cause of the subsequent tragedy. Therefore, no matter what kind of car you drive, keep a good distance and drive safely can effectively avoid accidents.

At the same time, we must also understand that although technology is developing at a high speed, it does not matter whether it is a high-end intelligent driving or not, and which manufacturer's high-end intelligent driving cannot be blindly trusted, because no technology can be foolproof. So we have to keep our safety in our own hands as much as possible, because we are the first to be responsible.

In the world, there are many coincidences, if you encounter this kind of sprinkler in the picture, maybe the ending will be different. Finally, the deceased is greater, and I hope that there will be fewer traffic accidents in the world, and everyone can be safe.
