Recently, there has been a new development, the accident simulation route has been restored, Xiaomi suddenly deleted Weibo after meeting with the family, netizens saw this scene and complained directly: Is the money in place? Just delete Weibo?
Xiaomi SU7 high-speed car crash
On the evening of March 29th, there was an accident in the Chiqi section of the Anhui Deshang Expressway, a Xiaomi SU7 was carrying three young girls to Anhui to take the career preparation exam, who knew that the misfortune happened, a disaster ruthlessly took their lives.
According to Xiaomi's official investigation, before the accident, the accident vehicle turned on NOA intelligent assisted driving and drove at a speed of 116km/h in the Chiqi section of the Deshang Expressway.
At that time, the road section where the incident occurred was under construction, the lane was closed, and the vehicle needed to be diverted to the opposite lane.
The vehicle detects an obstacle in front of it, quickly alerts it, and automatically starts to slow down, and when it detects an abnormality, the driver immediately manually takes over the vehicle to control it in an attempt to avoid danger.
However, despite the driver's timely response, the car eventually crashed into the cement pile of the barrier at a speed of about 97 km/h.
After the accident, the victims' families spoke out, questioning why the vehicle suddenly spontaneously combusted after hitting the guardrail, and why the door was locked and could not be opened, so that the people in the car had no chance to escape.
The family said that the driver was their 23-year-old daughter, who got her driver's license three years ago.
In October last year, my daughter's boyfriend bought this Xiaomi SU7, and my daughter drove to Foshan alone, so she is quite familiar with the performance of the car.
At 11 o'clock on the night of the accident, the family got the news and immediately rushed to Anhui, arrived at the accident site at almost 3 o'clock in the morning, and the road was closed when he arrived, and he saw the car being dragged down, and the toll station staff said that two funeral home cars pulled away two bodies, and one person was sent to the hospital for rescue.
After inquiring with the traffic police, the family learned that the road was being repaired in front of the road, and the car caught fire after hitting the cement pile, and the car door could not be opened, and the daughter and her classmates were trapped by the fire and had no time to escape.
On March 31, the family saw their daughter's body, which was burned to charcoals and completely unrecognizable.
Asked the traffic police about the situation, and learned that the road was being repaired in front of the accident, the vehicle spontaneously combusted after hitting the cement pile, the car lock could not be opened, and his daughter and another classmate were burned alive, and he only saw his daughter's body on March 31, which was burned to charring and could not recognize anyone.
On the afternoon of April 1, a spokesman for Xiaomi released the details of the investigation, saying that a special team was set up as soon as possible after the accident, and rushed to Tongling on the 30th, fully cooperating with the police investigation and collecting evidence, and submitted vehicle driving data and system operation information to the police on the evening of the 31st.
Xiaomi said that it will spare no effort to cooperate with the police in the follow-up, and will definitely make the handling of the entire incident open and transparent, and Xiaomi will also take the initiative to communicate with the family members to help deal with the aftermath.
But the families of the victims were not satisfied with Xiaomi's approach, and Luo's mother said that until April 1, no one from Xiaomi took the initiative to contact the family.
She also questioned a series of problems such as the door cannot be opened, the vehicle spontaneously combusts, and the intelligent driving switching time is too short.
Luo's boyfriend also said that it has been 4 days since the accident, and Xiaomi has never taken the initiative to contact them, and the customer service's rhetoric is completely different from the actual situation.
On the afternoon of April 1, the reporter contacted Luo's boyfriend, who said that he had worked hard in Shenzhen all the year round, and he bought this car to make it more convenient for his girlfriend to travel.
He admitted that Xiaomi was right to contact him at the right time, but in addition, Xiaomi's various behaviors after the accident made him unconvinced.
As the incident continued to ferment on the Internet, Xiaomi's share price was also significantly affected, and on the afternoon of April 1, Xiaomi's stock price suddenly dived, once falling by more than 6%.
On the evening of April 1st, Lei Jun came forward to respond to the Xiaomi SU7 car accident, he said that the accident made him feel very uncomfortable, and three young girls died, no matter who the news is, it is a great grief.
On behalf of Xiaomi, he expressed his condolences to the girls who died, and also sent condolences to their families, Lei Jun also promised that Xiaomi would never evade, and would cooperate with the police investigation and strive to respond to the concerns of the family and everyone.
However, Lei Jun's voice and Xiaomi's response did not satisfy the families of the victims, who hoped that the company could give us a more detailed explanation, hoping to inform the public in detail whether the vehicle had potential safety hazards, so as to avoid further tragedies in the future.
The family deleted Weibo
In the past two days, a video of a simulated route has been circulated on the Internet, which is very similar to the scene of the accident.
Although this is not a dashcam video of the Xiaomi SU7 accident, but another high-speed collision, the similarity between the two is very high.
In the video, a car is driving on the highway at a speed of 112km/h, and it also encounters a high-speed construction section, the original two lanes become one lane, and there are warning signs, cones and speed warning signs on the road.
Just when he was about to hit the obstacle, the driver hurriedly intervened and hit the steering wheel left and right in a panic.
But in the end, it couldn't avoid the collision, and the speed of the collision turned out to be 97km/h.
It is worth noting that the mother of the victim has been speaking out continuously on the Internet, questioning the problems of the vehicle.
But recently, he suddenly deleted all related posts, only retained content such as recipes from many years ago, and set the comment area to no comments.
Seeing this scene, netizens were puzzled, maybe there was a new change in the situation.
Yesterday afternoon, Luo's boyfriend accompanied his girlfriend's parents to meet with Xiaomi staff, and the families of the other two victims were also present, everyone was waiting for the results of the investigation, hoping to give an explanation to the deceased.
It may be that there is new evidence, or that the traffic police have already made a preliminary judgment, or that there may be other reasons!
That's why Luo's family will delete the post, maybe today and tomorrow, there will be a formal announcement, and the result will be clear at that time.
Professor Zhu Xichan spoke
In the heated discussion triggered by the accident, the voice of Professor Zhu Xichan, who is from the School of Automobile Science of Tongji University, attracted the most attention.
Xiaomi officially pointed out that it was about 2-4 seconds from the time the NOA issued the risk warning to the collision, but Professor Zhu Xichan questioned the "2-second warning".
He did a simulator test, and the results were really sweaty, under normal circumstances, it takes the driver an average of 2.3 seconds to complete the takeover operation, and the average time from the system to the accident is 1.7 seconds.
In such a short time, how can the driver have time to react, and the warning time is obviously seriously insufficient.
In addition, Xiaomi also advertised that its own car can achieve a significant speed reduction when it is in a high-speed driving state, 130km/h, which can be reduced to 70km/h.
As a result, when the accident occurred, the speed of the car was still 97km/h, so looking at it, there was a high probability that the AEB would drop the chain and not start normally at all.
Professor Zhu Xichan explained that the car involved in the accident was the Xiaomi SU7 standard version, which was not equipped with lidar, and the light was not good at night, so it was difficult to find obstacles in time.
In addition, the accident section is under maintenance, and those obstacles are not easy to classify, and the system does not dare to brake urgently casually, so ABE did not start.
For the problem of vehicle fire and door failure to open after the accident, Professor Zhu Xichan analyzed that the current electric vehicles mostly use liquid electrolyte lithium batteries, and collision extrusion is easy to cause diaphragm rupture, short circuit and fire, like the side impact of nearly 100 kilometers per hour, fire is almost inevitable.
As for the door not opening, it is likely that the airbag did not ignite, or the circuit was interrupted.
Nowadays, most cars rely on the airbag control unit to unlock the door, and if the airbag is not ignited, the door cannot be unlocked.
From here, it can be seen that there is still a lot of room for improvement in our current vehicle safety standards.
Professor Zhu Xichan also reminded that some car companies reduce safety tips in order to make users feel better, which is too undesirable.
In the intelligent driving system, the alarm mechanism is the key to saving life, just say that this Xiaomi accident, the system just prompted, the car crashed, the time is ridiculously short, and the driver can't react at all.
Therefore, the intelligent driving system must call the police in time, if you encounter those drivers who are always distracted by driving, and remind the drivers who have been useless several times.
You have to turn off their NOA function, but you can't let them treat assisted driving as autonomous driving, otherwise it's too dangerous.
This incident reminds us that when traveling by car, safety is always a top priority.
Whether it relies on intelligent driving or traditional manual driving, drivers must always be highly vigilant and strictly abide by traffic rules.
Now we all hope that the police can investigate the final results as soon as possible, give a reasonable explanation to the families of the three young girls, and let us understand the truth of the matter, so as to avoid similar tragedies from happening again.
