On the evening of May 8, Mr. Li from Leiyang, Hunan Province drove a newly purchased Xiaomi SU7 car less than a month ago in the process of parking, the brake was suspected to have suddenly failed, and an alarm sounded in the car, and then 4 abnormal messages such as "braking system failure" appeared on the screen. After the vehicle came to an automatic stop due to the slow reversing speed, Mr. Li called the SOS emergency system in the car, but no one answered for a long time, an hour and a half later.
Wang Hua, general manager of the public relations department of Xiaomi Group, said that it was indeed a misidentification of the software. At present, we have fixed this small probability event, so you don't need to panic.
To put it mildly, empathize with it.
Local roadside assistance arrived to tow the vehicle back to the Changsha delivery center. Strangely, the car suddenly "healed itself" after being sent for inspection. After the sale, he said that he could drive away at any time, but Mr. Li did not dare.
After the sale, he said that he could drive away at any time, but Mr. Li did not dare and asked to find out the cause of the failure.
If the computer is broken, it can be restarted, but if the brakes fail, life may not be able to be restarted.
The driver still understands priorities.
There is no trivial matter in building a car, and restarting it can do the trick
Airplanes are sophisticated means of transportation, and there are strict maintenance procedures, and there are strict requirements for which screws are used for how long and when to be replaced.
As long as you follow the process, there will be no major problems in the life cycle.
If it goes out and excludes the human factor, it must be a design problem.
The solution to the problem is to face the problem head-on. For this reason, the United States has a special documentary "Air Catastrophe" to record the air crashes that have occurred in history.
I've watched many seasons, and after watching too much, I have a very intuitive feeling: human beings are not to be trusted.
When designing an airplane, it will basically follow the most cutting-edge technology of the moment, which is habitual thinking.
After all, airplanes are the most cutting-edge technology that ordinary people have access to.
But the air crash documentary mentions an interesting theory: when designing complex systems, the principle of simplicity should be followed as much as possible.
The general idea is that the system itself is already very complex, and if there is no way to avoid it, it is still necessary to streamline and split the functional modules. Avoid multifunctional integrations.
The reason is backwards, the aircraft will definitely have faults, and the high degree of functional integration and high complexity in troubleshooting will increase difficulties and uncertainties.
It is not conducive to the stable operation of aircraft systems.
With the full electrification of aircraft systems, there are few mechanized components, but the reliability and certainty of mechanical components have not been fully inherited by electronic systems.
So although there is an aircraft autopilot system, two pilots are still needed as safety supervisors.
With the intellectualization and electronicization of automobiles, automobiles are also facing such problems.
The basis of intelligence is electronic mechanical parts, and traditional mechanical parts have been verified for reliability and safety.
Digitalization includes software systems, electrical function modifications.
As we all know, software is unstable, and engineers are used to sacrifice to the sky.
The software system bug of Xiaomi Su7 will disappear after restarting, and the principle is like a computer blue screen restart.
But restarting will not solve the problem fundamentally, it will only ignore the problem.
Mr. Li doesn't know cars, but he must have used a computer.
Who hasn't had a BSOD reboot experience?
But the car is different from the computer, and if the computer is broken, it will not cause any bad effects, and if the car system is broken, it is a joke.
A computer can be restarted countless times, but a human life cannot be restarted.
Therefore, no matter how to guarantee sales, Mr. Li will be skeptical.
If you don't understand, you have to ask
Baidu's No. 1 public relations position has left, and she used to be Huawei's public relations spokesperson.
Netizens wondered why such a person could be Huawei's vice president and Baidu's No. 1 position.
Although most people don't quite understand what public relations is for, the No. 1 position and the vice president still recognize it, and the official position is not low.
But whether it is Huawei or Baidu, the R&D strength is indeed very strong, and in a sense, there is still a certain mass base.
How can you choose such a person to be an executive?
The masses don't believe that they are blind, and they don't believe that Dachang, who worships the gods, is so casual.
People only believe what they want to believe, and if they don't want to believe, they have to find a magic circle.
As the No. 1 Wang Hua of Xiaomi's public relations, he fully learned from the experience of his predecessors and went to the engineers of the automotive department to help sort out the situation.
This is the first time that an automotive engineer has been taken seriously by the PR department.
Once upon a time, the engineer just didn't understand Fengyue, oh no, a rough man who didn't understand the amorous style, and he was demented and annoying.
Now I can also be greeted by the boss of the exquisite public relations department, which can be regarded as an eye-opener.
The reply was also very engineer: the system of the main brake controller (DPB/BCP) of the vehicle at the time misidentified the situation where the degradation triggered the backup braking strategy, and the brake auxiliary controller (ESP/BCS) directly responded to the braking demand to provide the vehicle with brake deceleration.
Can't you understand it?
In fact, it is very simple, it is four words: software problems;
In detail, there is a software problem with the braking system.
It goes without saying that the brakes are heavy or not, and software problems are common, especially for internet companies.
It is right to work slowly and carefully, and the car also needs to be slow, and slow is fast.
But Internet companies are the most speed-oriented.
Will be a guinea pig into a bowl
Lei Jun posted today: Since the first delivery on April 3, in 43 days, we have delivered 10,000 vehicles! This is a major milestone for Xiaomi.
Lei Jun has always emphasized that he has spent 3 years concentrating on building cars, and his words are always very difficult, very hard, and he wants everyone to understand.
It is understandable to build an APP in 3 years, and it is impossible to build a car in 3 years, a good car, a car that is functionally passable and trustworthy in safety.
On August 16, 2011, the first product of Xiaomi mobile phone was officially released, and the mobile phone ID design was all completed by Xiaomi's internal hardware team from Motorola, and the mobile phone production was made by Foxconn and Inventec.
At this time, more than a year has passed since the establishment of Xiaomi.
It's very suitable for Lei Jun's evaluation of Xiaomi mobile phones. At present, it seems that it is quite suitable for Xiaomi cars.
Mobile phones and automobiles are both industrial products, and industrial products follow the logic of science, and the more mature they are, the fewer problems they have, and the more reliable they are.
At the annual speech in 2021, Lei Jun said: Ten years ago, Xiaomi 1 went on sale, 1999 yuan, 184,600 units, 370 million, which was Xiaomi's first income. With this income, we have developed on a rolling basis, and only then have today's Fortune 500 and today's world's second!
Lei Jun announced at that time that he would refund the income of Xiaomi Mobile Phone 1 and give each person a red envelope of 1999 yuan.
Perhaps the first users of Xiaomi cars can also wait for a relocation payment.
Cancer is the biggest killer of contemporary human beings, and biomedical companies are the greatest hope for treatment through cutting-edge scientific and technological innovations.
But life has a price, just like ordinary people in "The God of Medicine", they can't afford expensive targeted drugs, some people choose generic drugs, and some people choose to "participate in trials".
The research and development of new drugs requires monkeys, mice, and humans to do the final technical verification.
But there are no people who are willing to do experimental mice.
Therefore, in order to recruit trainees, oh no, human experimenters, biopharmaceutical companies have put up the name of "recruiting volunteers", promising free treatment, and some transportation and accommodation subsidies are not a problem.
If you succeed, you will be happy, and if you fail, you will be silent.
