[PConline application] When many friends buy computers, they will pay attention to the power consumption of CPU. For example, if you buy a desktop, you should allocate power according to power consumption, while the power consumption of a notebook CPU is related to performance and heat generation. How to look at power consumption? Many people will refer to the official TDP data, for example, the TDP of the i7-9900K desktop is 95W, and that of the i7-10710U notebook is 15W. However, this data can’t actually reflect all the problems, and it never represents the real power consumption of CPU.

　　Nowadays, CPU has the function of automatic frequency adjustment, which means that its power consumption fluctuates within a certain range. For example, in the case of Turbo Boost, the power of hardware is much higher than TDP.

Intel CPU has four power gears, and TDP often only represents PL1.

　　Intel’s CPU is a typical example. Intel has defined four extreme power gears for SoC, which are PL1, PL2, PL3 and PL4 as shown in the figure. Among them, PL1 is the average power, and its power is closest to the TDP mark, and the CPU is allowed to keep it at this power level all the time. However, PL2 is higher than PL1, and the CPU can keep at the power of PL2 for 100 seconds, and the turbo frequency is generally in PL2 state. PL3 is a higher level, and the CPU can stay in this power level for 10 milliseconds. PL4 is the power ceiling, which is not allowed to be crossed.

　　It can be seen that TDP can only represent the power gear of PL1 level, and the power of CPU in actual use is much higher than this. If you calculate the power consumption according to TDP, the performance of heat dissipation and power supply under high load may deviate far from your expectations. Why does the computer suddenly restart with a black screen when rendering? Why is the notebook hotter and noisier than expected? Often, the actual power consumption of CPU is higher than your estimate, so it is meaningful to know the real power consumption of CPU. So the question is coming, what should we do?

　　Ordinary users don’t have a professional power consumption meter, but through some software, you can also get a general understanding of the real power consumption level of CPU. For example, this HWINFO is such a software.

　　HWINFO：Click here to enter official website.

　　In fact, HWINFO is quite famous in the player circle. It is a professional hardware monitoring software from abroad. It is free, has a green version and is very clean. Unfortunately, the software doesn’t support Chinese at present, but if it is used to monitor CPU power consumption, there is not much obstacle.

After HWINFO is opened, the hardware information that can be monitored is very rich.

　　When you turn on HWINFO, the software will automatically pop up the information and monitoring interface about CPU by default, and you can also view a variety of hardware information in the main interface, but these are not the focus of this article, and interested friends can experience the research slowly.

　　Click the "Sensors" button in the main interface to view various sensor information of this computer, including the power consumption of CPU. Find the column "CPU Package Power", which is the power consumption level of CPU.

Click the "Sensors" button.

The readings of various hardware sensors of the computer can be seen one by one.

　　In this column, you can see the current real-time power consumption of CPU, as well as the maximum and minimum values that have been reached. And if you use Intel CPU, you can also see the settings of PL1 and PL2.

You can see the CPU Package Power and the setting of PL1 and PL2 gears.

　　In this way, it is very simple to test the maximum power consumption that the CPU can achieve. You can start some high-load tasks and observe the maximum power consumption of CPU, which generally will not exceed the power consumption limit of PL2. And we know that CPU has a temperature wall in addition to the power consumption wall, so the heat dissipation can’t pass, and the power consumption of CPU can’t even reach the level of PL1. Therefore, it can be seen at a glance how much energy CPU can actually release in combination with copying software.

　　Generally speaking, HWINFO is really a very powerful software. But it also has a small regret, that is, the support for some CPU may not be very good — — For example, some APUs of AMD mobile platform can’t accurately display the power consumption value. After all, it is not an official software, and it can’t guarantee that all hardware readings are accurate. In addition, there is more than one software that can see CPU power consumption, but HWINFO has relatively comprehensive support for all kinds of sensors. If you also want to have a deeper understanding of hardware, you might as well try it.

　　General Secretary of the Supreme Leader made many important speeches on high-quality development when he participated in the deliberations of delegations from Inner Mongolia, Guangdong, Shandong and Chongqing. The deputies said that to build a modern economic system and achieve high-quality development, we should conscientiously implement the economic thought of Socialism with Chinese characteristics, the supreme leader in the new era, make great efforts in learning and understanding, faithfully perform our duties, and work hard to achieve tangible results and promote sustained and healthy economic and social development.

　　Learn and understand Socialism with Chinese characteristics’s economic thought in the new era of being the supreme leader.

　　To promote high-quality development, we must first learn and understand Socialism with Chinese characteristics’s economic thought in the new era of being the supreme leader. "Standing at the height of the national strategic pattern of coordinated development of Beijing-Tianjin-Hebei, the General Secretary of the Supreme Leader directed the pulse and laid out the layout for the high-quality development of Beijing’s economy, leading Beijing into a new era of development. An important content is to change from gathering resources for growth to resolving functions for development. " Deputy Tan Xuxiang, director of the Beijing Municipal Development and Reform Commission, said that during the transition from high-speed growth to high-quality development, the economic structure has undergone major changes, residents’ consumption has been accelerated and innovation has entered an active period. If the way of thinking remains on the old road in the past, it will not only be difficult to find a way out, but also miss the opportunity. Beijing is striving to build a science and technology innovation center, and the contribution rate of scientific and technological progress to economic growth exceeds 60%. At the same time, adhere to the people-centered development idea, closely meet the better life needs of the citizens of the capital, such as convenience, livability, diversity, fairness and safety, intensify pollution control and optimize the supply of public services.

　　"To implement Socialism with Chinese characteristics’s economic thought of the Supreme Leader in the new era, we must adhere to the new strategy of problem-oriented deployment of economic development and adhere to correct working strategies and methods." Deputy Ding Xiufeng, Mayor of Tangshan City, Hebei Province, introduced that in 2017, Tangshan faced the problem of backward production capacity, solidly promoted the supply-side reform, and eliminated the steelmaking capacity of 9.93 million tons and the ironmaking capacity of 5.76 million tons. The profits of industrial enterprises and the added value of high-tech industries increased by 70.7% and 17.2% respectively. In terms of strategies and methods, it is proposed to "break", "establish" and "drop", build a modern industrial system and a supporting modern service system that fits Tangshan’s resource endowment and accelerates the transformation of old and new kinetic energy, and strive to build nine emerging industrial clusters such as special robots and rail transit equipment.

　　In recent years, all localities and departments have insisted on making the market play a decisive role in the allocation of resources and give better play to the role of the government. Deputy Lei Jun, Chairman and CEO of Xiaomi Company, said that the government departments have implemented targeted measures in macro-control, simplified administration and decentralized power on a large scale, and actively built a new type of political and business relationship, which has created an unprecedented good development situation for China enterprises. Zhongguancun Park has implemented a number of systems on high-end talent management reform, greatly simplifying the procedures for talent introduction, and Xiaomi’s core technology research and development and international business development have also received tangible support.

　　Focus on promoting the transformation and upgrading of industrial structure and make the real economy stronger and better.

　　There are many traditional industries and few emerging industries, many low-end industries and few high-end industries, many resource-based industries and few value-added industries, and many labor-intensive industries and few capital-and technology-intensive industries. This is the current situation of many regional economic systems. "The general secretary stressed that to promote high-quality economic development, we should focus on promoting the transformation and upgrading of industrial structure." Deputy Wang Shuhua, Chairman of Handan Wu ‘an Yuhua Iron and Steel Co., Ltd. said that the steel production capacity of private steel enterprises accounts for more than 70% of Hebei’s steel production capacity, but the proportion of high-end steel products and high value-added products is still low, so it is necessary to improve the scientific and technological content and added value of products and extend the industrial chain. He suggested that a catalogue for guiding the development of high-tech products in traditional industries should be formulated, and a special fund for innovation support in traditional industries should be set up to encourage more enterprises in traditional industries to increase investment in scientific and technological research and development.

　　"To revitalize and develop the old industrial base, we must vigorously cultivate new industries, new kinetic energy and new growth poles while optimizing and upgrading the stock, and aim at emerging industries such as intelligent manufacturing, new materials and biomedicine." Deputy Yu Gongbin, Mayor of Yingkou City, Liaoning Province, said that Yingkou must not take the old road, but rely on the Yingkou area of Liaoning Free Trade Zone to form an emerging industry represented by advanced equipment manufacturing, new magnesium materials and fine chemicals. Last year, the city transformed 50 scientific and technological achievements and added 20 state-level high-tech enterprises.

　　"General Secretary of the Supreme Leader pointed out during his investigation in Hebei that China is a big country in dairy production and consumption, and we must make up our minds to make the dairy industry stronger and better. At the two sessions of the National People’s Congress, the General Secretary once again emphasized making the real economy stronger and better. " Deputy Wei Lihua, president of Junlebao Dairy Company, said that the real economy can create social wealth and provide jobs, and only by actively supporting and serving various market players in the real economy can it provide strong support for high-quality economic development. He hopes that government departments will create more relaxed and favorable policies for enterprises, provide efficient and convenient services, improve the efficiency of examination and approval, improve service levels, and attract more entities to participate in innovation and entrepreneurship.

　　Building an institutional mechanism to promote high-quality economic development is a systematic project, which should be considered comprehensively, focused on the long term, focused on key points and grasped the key points.

　　At present, the high-quality economic development faces some drawbacks and obstacles in the system and mechanism, especially the inefficient allocation of resources and the lack of freedom in the flow and aggregation of innovative resources and factors. "Promoting the concentration of resources to high-quality enterprises and products, the most precious resource for us is innovative talents." Commissioner Tan Jianfeng, chairman of Shanghai Zhongren Network Security Technology Company, said. In the past five years, there have been more than 500 creative spaces in Shanghai, five times that of five years ago. Government departments should give greater support to technology-based entrepreneurial enterprises, not only to introduce talents, but also to retain them. It is suggested that more clear and enforceable policies should be introduced to solve the problems of housing, settlement and children’s education of outstanding talents and create a better innovation and entrepreneurship ecology.

　　How to build high-quality system supply, service supply, factor supply and complete market system to enhance the attractiveness and competitiveness of the development environment? "This year, Sichuan should deepen the reform of the property right system of post scientific and technological achievements and strive to break down the barriers to the transfer and transformation of scientific and technological achievements. This is an important practice to improve the market system." Member Zhang Yudong, president of Chengdu Branch of Chinese Academy of Sciences, said that at present, the transformation of scientific and technological achievements in our state-owned scientific research institutions is not smooth and inefficient, and there are policy and legal obstacles in the market-oriented transfer of intellectual property rights in public institutions, and the approval period for intellectual property rights evaluation is long. It is suggested to establish relevant market evaluation mechanism to evaluate scientific and technological achievements more effectively and accurately. Only when all the elements involved in the process of scientific and technological transformation, such as scientific research, management and manufacturing, are effectively encouraged can the attraction and competitiveness of the development environment be enhanced.

　　Focusing on improving the level of green development, Zhang Baoshun, member of Chinese People’s Political Consultative Conference and deputy director of the Environment and Resources Protection Committee of the 12th National People’s Congress, said that in some places, the industrial structure is biased, the energy structure is dark, and the efficiency of resource utilization is low. Some local party committees and governments are not smooth in implementing the green development transmission mechanism, and there are not many ways and actions. Deputy Hong Jie, Chairman of Fujian Sanshu Coatings Company, believes that high-quality economic development can not be separated from high-level green development level, and the state attaches great importance to this, which has brought great confidence to many enterprises with green consumption and green production. Green development is not only reflected in products, but also throughout the whole process of production and supply, and the strictest green standards should be implemented from the beginning of factory site selection and construction. The production cost of green environmental protection enterprises is high, so it is suggested to introduce more tax reduction and burden reduction measures for green industries to further promote the development of green industries.

　　Dennis Austin put forward at least half of the main design ideas and took full credit for the smooth performance and perfect completion of PowerPoint. "If Dennis wasn’t the one who designed PowerPoint, no one would have heard of it."

　　"It’s easy to laugh at the corporate nature of PowerPoint, but the real story is its participation and democracy. High school students use it, rabbis (Jewish wise men) use it, and people even use it for wedding toasts. "

　　On September 1, local time, Dennis Austin, the inventor of PowerPoint, died at his home in Los Altos, California, at the age of 76.

　　According to Washington post’s report on September 8th, Michael Austin, Austin’s son, revealed that the cause of death was the metastasis of lung cancer to the brain.

　　PowerPoint has played an important role in shaping the way of information communication in modern society and has become synonymous with the workplace world. Its amazing popularity, especially the ability to easily create boring and endless presentations, makes it not only a tool that everyone can’t live without, but also a rare cross-cultural symbol. No matter in which country, PowerPoint is easy to be ridiculed and entertained in cultural and artistic works. It also has a household abbreviation: PPT.

　　Everyone can make slides.

　　In 1987, as the digital successor of projector, PowerPoint was released by the software company Forethought. Prior to this, making slides was a labor-intensive task, which was usually assigned to the design department or outsourced. PowerPoint allows anyone who can use a computer to make slides, just click with the mouse and rearrange the information.

　　As a software engineer, Austin cooperated with Robert Gaskins, the Forethought executive who conceived the software, to make PowerPoint easy to operate.

　　"Our users are familiar with computers, but may not be familiar with graphics software." Austin wrote in an unpublished article about the history of PowerPoint development. He made "the content you are editing look exactly like the final product" through the "direct operation interface".

　　PowerPoint was originally called Presenter. At first, it provided users with the functions of merging graphics, clip art and multiple fonts for Apple Macintosh computers with graphical interfaces. Austin wrote that the goal is "to create presentations, not just slides."

　　Gaskins wrote in his book "Sweating Bullets: Notes on Inventing PowerPoint" that "Dennis put forward at least half of the main design ideas" and took full credit for the fluency and perfect completion. "If Dennis wasn’t the one who designed PowerPoint, no one would have heard of it." Gaskins added.

　　A few months after PowerPoint was launched, Microsoft acquired Forethought for $14 million. Microsoft founder Bill Gates was skeptical at first, but finally changed his mind. This project is so huge that Microsoft has set up a new business department.

　　Microsoft finally added PowerPoint to the Office suite, which was released on the Windows operating system in 1990. By 1993, the sales of PowerPoint had exceeded 100 million dollars. Now, users around the world use PowerPoint to create more than 30 million presentations every day.

　　Global users now use PowerPoint to create more than 30 million presentations every day.

　　PowerPoint was rejected by Jobs.

　　However, in the process of becoming an important tool in the workplace, PowerPoint was ridiculed by corporate executives, business school professors and military officers.

　　"I hate the way people use slide shows without thinking." According to Walter Isaacson’s Biography of Jobs, Apple founder Steve Jobs said, "People will face problems by creating presentations. But I want them to get involved and discuss problems on the table instead of showing a bunch of slides. People who know what they are talking about don’t need PowerPoint. "

　　Jobs banned the company from using PowerPoint (but Apple developed its own demo software). Jeff Bezos, the founder of Amazon, did the same and asked the executives to write a memo to share before the meeting.

　　At the Pentagon, PowerPoint was criticized. "PowerPoint makes us stupid." According to The New York Times, former US Secretary of Defense Jim Mattis said at a military conference in 2010, "We have met the enemy, and he is PowerPoint."

　　"This is dangerous because it will create the illusion of understanding and control." Lieutenant General H.R. McMaster of the US Army told reporters.

　　In 2003, NASA’s committee investigating the disintegration of the space shuttle Columbia found that a PowerPoint slide used "sloppy" and "vague quantitative words" to cover up the "life-threatening" safety problem of the spacecraft. The report said: "The Committee believes that PowerPoint presentation slides are widely used instead of technical papers, indicating that there is a problem with NASA’s technical communication methods."

　　Austin and Gaskins agree with these complaints, but think that they unfairly point the finger at the software, rather than the people who use it for lazy and poor demonstrations. "It’s like a printing press." Austin told The Wall Street Journal in 2007, "It can print all kinds of rubbish."

　　"The real story is participatory and democratic."

　　Austin was born in Pittsburgh, USA on May 28th, 1947. His father runs an executive association, and his mother is a typist and later becomes a housewife.

　　When Austin was studying engineering at the University of Virginia, he used a room-sized computer. Students programmed on the machine to generate punch cards, and then specially trained computer operators entered it into the computer. After the program was running all night, the students came back the next day to check the output.

　　After graduating in 1969, Austin studied for graduate students at Arizona State University, Massachusetts Institute of Technology and University of California, Santa Barbara. Subsequently, he worked in companies such as General Electric and Honeywell International.

　　In 1984, Austin was hired by Forethought, a company founded by two former Apple employees.

　　After Microsoft acquired Forethought, Austin continued to lead the development of PowerPoint until his retirement in 1996.

　　Austin’s friends and family said that he never mind jokes about PowerPoint. He is also well aware that the software he invented was used for demonstration purposes far beyond expectations, not only as a proposal, but also as a prop in stand-up comedy performances.

　　In 2005, Austin attended an event at the University of California, Berkeley, when David Byrne, the lead singer of the rock band Talking Heads, gave a PowerPoint presentation to show the use of the software to create art.

　　"PowerPoint is the Rodney Dangerfield of software: it is not respected." Ken Goldberg, the organizer of the event and an engineering professor at the University of California, Berkeley, said. Denzelfeld is an American stand-up comedian who is famous for his self-deprecating witty humor. His famous slogan is "I can’t get respect!" .

　　"It’s easy to laugh at the corporate nature of PowerPoint, but the real story is its participation and democracy. High school students use it, rabbis (Jewish wise men) use it, and people even use it for wedding toasts. " Goldberger said.

No one may have expected that a vertical category exhibition at the Shanghai Auto Show has become a well-known livelihood event because of the rights protection action of Tesla female car owners in Anyang, Henan Province. After three days of fermentation, at the request of Zhengzhou Zhengdong New District Market Supervision Administration, the "arrogant" Tesla finally promised to provide the driving data of female car owners in Anyang half an hour before the incident, and also demanded in its official statement that "the truth should be restored as soon as possible".

In the past two years, Tesla’s spontaneous combustion, out of control, brake failure and other issues have repeatedly exposed the world’s largest electric vehicle manufacturing company from the United States to the spotlight.

According to incomplete statistics, in the past two years, there were more than 20 serious accidents of Tesla vehicles exposed, among which "sudden acceleration, vehicle out of control and brake failure" became the biggest cause of accidents.

In response to these accidents, Tesla often denies the existence of vehicle design defects and throws the problem back to the driver, thinking that the driver’s human error is the biggest cause of the accident. At this point, a Rashomon-style discussion on responsibility identification has become a catalyst to intensify the contradiction between consumers and Tesla, and it has not been concluded yet.

In the past year, many Tesla lost control, and the car owners and manufacturers held their own words.

The source of the rights protection incident of the female car owner of this Shanghai Auto Show comes from a traffic accident of the car owner and his family during the Spring Festival this year. According to the description of the female car owner, at that time, because of the "brake failure" of Model 3 driven by her father, after two cars were continuously rear-ended, they finally hit the cement fence on the roadside and stopped. The accident caused the female car owner’s parents to be injured and hospitalized.

According to the test results given by Tesla, the speed of the crashed Model 3 was as high as 118.5 km/h, but no vehicle abnormality was found during braking. In the end, this hasty conclusion became the last straw to crush the camel, which attracted media attention and pointed the finger at Tesla’s official reply.

This time, the owner of Anyang, Little White Car Girl, published a response to Tesla’s official statement in Tencent News, expressing dissatisfaction with the so-called appraisal results given by Tesla, including "whether the vehicle is speeding", "the qualification of the appraisal agency" and "the brakes are slammed but the braking effect is not obvious", which have become the intensification points of contradictions between the two sides.

After the Anyang incident in Henan Province was exposed, on March 11th and 12th, the media exposed two safety accidents of Tesla respectively. The Tesla owners in Haikou, Hainan and Shaoxing, Zhejiang Province all suffered traffic accidents because their vehicles were out of control.

According to incomplete statistics, from May 2020 to March 2021, there were more than 21 reported Tesla vehicle accidents, among which there were even "major traffic accidents" with 2 deaths and 6 injuries. Among the vehicles with accidents, it is not limited to Model 3, including imported Model X and S..

At present, for Tesla cars that have accidents due to active collision of vehicles, most of the reasons reported by the owners point to the situation that "the vehicle will suddenly accelerate, resulting in out of control and the brake pedal will fail", but so far, no accident vehicle has been identified as a vehicle problem by relevant departments or testing institutions, which has also led to an online rashomon debate.

Careful analysis of the time of these Tesla accidents in the past year is not difficult to find that in the past four months, the exposed Tesla accidents accounted for 67% of all incidents in the past year.

The outbreak of excessive concentration has also made Tesla’s public opinion reach an unprecedented height in the last year, which is why Tesla was asked to board the CCTV 3.15 party before 3.15.

Especially in 2021, the frequency of accidents in Tesla has increased significantly. In the first three months of this year, the number of car accidents in Tesla accounted for almost half of all the events in the past year.

On the one hand, this is related to the accidental traffic accidents, on the other hand, it also reflects Tesla’s vehicle business, especially the sales of domestic Model 3 have indeed reached a certain order of magnitude in the China market.

In the ranking of mid-size car sales in March this year given by the Federation, Tesla Model 3 rode the dust, leading the second BMW 3 Series by as much as 45%, and many traditional car manufacturers were pushed behind it. Model Y, which was officially launched in January this year, was once reported to have scheduled orders for June.

The user’s purchase of Model 3, coupled with the driving experience of electric vehicles different from traditional gasoline vehicles (fast acceleration and single pedal mode), may be one of the main reasons for Tesla’s recent frequent vehicle accidents.

Judging from the geographical distribution of accidents, as the sales of Model 3 continue to rise, Tesla’s penetration rate is quite amazing. Eleven provinces, municipalities and autonomous regions were involved in all the 21 accidents exposed, including not only new first-tier cities like Hangzhou, but also prefecture-level cities like Nanchong in Sichuan and Linyi in Shandong.

It is not difficult to find out on Tesla’s official website that Tesla has service centers in 28 provinces, municipalities, autonomous regions and special administrative regions in China, except Qinghai, Ningxia, Xinjiang, Tibet, Gansu and Inner Mongolia. You can buy Tesla in any province and city.

The huge market expansion speed allows Tesla to enjoy the market benefits brought by the government’s vigorous promotion of electric vehicles, but it also puts forward stricter requirements for Tesla’s vehicle production and after-sales service quality.

On February 8 this year, Tesla was interviewed by the State Administration of Markets, the Central Network Information Office, the Ministry of Industry and Information Technology, the Ministry of Transport and the Fire and Rescue Bureau of the Emergency Management Department due to abnormal acceleration, battery fire and OTA.

Obviously, the scale and investment of Tesla Company in production and after-sales are difficult to match the rapidly growing China market.

In all the accidents exposed in the past year, except for the damage or spontaneous combustion of the vehicle itself, 80% of all the accidents were caused by the "out-of-control" impact, which caused damage to other vehicles or public facilities, and the electric vehicle accelerated quickly.

When the so-called "out-of-control" situation happens, it is often difficult for car owners to have good control over the collision consequences of vehicles, so more news we see is quite incredible, such as "Tesla rushed into the toilet and rushed into the hotel lobby" and so on. In all the accidents, there were 2 reported deaths, and more than 12 people were injured to varying degrees.

Tesla, a pure electric vehicle, can quickly improve the speed of the vehicle in a short time. According to the official data given by Tesla, the domestic Model 3 standard endurance version can accelerate the car to 100km/h in 5.6 seconds. If it is a high-performance version, this time will be shortened to 3.3 seconds.

This kind of extreme speed performance is enough to cause a greater impact on the surrounding environment than that of a traditional car in a relatively short distance, so when the vehicle "accelerates out of control", Tesla is likely to cause more serious traffic accidents.

In all the incidents, there were 13 cases in which the owner explained the accident. Among them, the words most frequently mentioned by accident owners include "the vehicle is out of control", "the brake (brake) is out of order" and "the speed is too fast".

In the 11 cases that Tesla answered specifically, Tesla often appeared in the form of "throwing a pot", and the official basic wording was similar, including "not stepping on the brake pedal", "there is no quality problem", "stepping on the accelerator pedal" and so on.

This contradictory dialogue has become the focus of controversy between the owner and Tesla. The owner thinks that Tesla’s vehicle is out of control because of the quality of the car or design defects, while Tesla will tell you through "various data" that it is the owner’s driving mistakes that lead to the final incident.

Rashomon discussions have never stopped in the past year.

The initiator of Tesla’s rights protection incident at the Shanghai Auto Show, which angered netizens, was Tesla’s vice president Tao Lin’s reply to this incident in an interview with the media.

"She contributed to the recent negative", "We can’t compromise, which is a necessary process for the development of a new product" and "Our own research shows that 90% of our customers are willing to choose Tesla again", etc., making onlookers stunned.

On the one hand, the owner fiercely defended his rights, and on the other hand, it was the official answer of Tesla’s shabu-shabu style.

Almost every time a vehicle has an out-of-control acceleration failure, Tesla’s official investigation gives a rhetoric similar to "the driver stepped on the wrong pedal and the vehicle did not break down." This made the owner of the accident unacceptable, and also made netizens express dissatisfaction with Tesla’s "irresponsible" official reply again and again. Tesla was therefore named "master of shabu-shabu" by netizens.

Behind the "shabu-shabu" again and again, it seems that Tesla’s attitude is arrogant, but in fact, the "black box" data that Tesla uses as an official explanation every time is the original sin that pushes them to the forefront.

The so-called "black box" is a chip installed by every automobile manufacturer to store the accompanying data, which can record all the states experienced by the driver in the process of driving the vehicle.

Especially in the process of collision, whether the driver has improper driving operation or the vehicle itself has made a major mistake depends on the data recorded in the black box as an important judgment basis.

In the runaway accident of Tesla in the past year, Tesla officials have repeatedly proved that the vehicle itself is safe and reliable according to the data provided by the black box. But the problem is that the data in this black box is confidential and Tesla has never made it public.

When there is a major traffic accident in Tesla’s vehicle, Tesla will often contact the owner to get the vehicle back or get the accident vehicle at the scene at the first time, and read the data of the black box to determine whether the accident is caused by the failure of the vehicle itself.

What data did Tesla take from the black box?

Are these data as real as the published results?

Did Tesla tamper with the data twice?

……

These problems are unknown to consumers, especially accident owners, which has become one of the main contradictions.

In addition to Anyang female car owners’ accusation that the vehicle is out of control for Tesla’s appraisal results, Haikou brake failure car owners released their "Seven Questions about Tesla, won’t your conscience hurt?" "wrote:

"As we all know, Tesla’s background data has never been made public, and only the owners of limited out-of-control events have been informed by oral communication. This way of being both a referee and an athlete cannot convince people of the authenticity of its data. "

Although this black box model is widely used by automobile manufacturers around the world, it is naturally difficult to convince Tesla that it can only provide such non-public data every time it determines its responsibility.

After Tesla announced the latest response last night and confirmed that it would provide the driving data of female car owners in Anyang half an hour before the incident, many netizens also expressed concern about the authenticity of the data.

Rashomon-style discussion can’t reach a conclusion, but for out-of-control Tesla cars, a reasonable explanation must always be given. Perhaps the investigation report of National Highway Traffic Safety Administration (NHTSA) can give us a conclusion.

On January 13, 2020, the National Highway Traffic Safety Administration (NHTSA) launched an investigation into the allegation that Tesla was out of control and accelerated, requiring it to recall vehicles with design defects. Finally, after a year-long investigation period, NHTSA announced the relevant investigation results on January 8 this year.

NHTSA investigated 246 cases of runaway acceleration of Tesla in one year. The final report shows that all 246 cases were caused by the driver’s wrong pedal.

According to the description in the NHTSA report, they made a detailed analysis of 217 accidents included in the investigation, including 118 Tesla vehicles for which they obtained vehicle trip data.

According to the trip data, 85% or even 97% of the 118 vehicles accidentally accelerated and caused accidents when the accelerator pedal of the vehicle was stepped on. In 97% of the accidents evaluated, the pressure exerted on the accelerator pedal reached its peak within 2 seconds of the collision. In 90% of the accidents evaluated, the brakes were not pressed, and the remaining 10% were pressed less than 1 second before the collision, that is, the brakes were pressed late. About 51% of the evaluated accidents occurred within 6 months of the owner driving Tesla.

These 246 cases and the nearly 20 cases in China mentioned above have a common feature, that is, the so-called "runaway acceleration of vehicles". In these case reports received by NHTSA, most drivers claimed that "Tesla vehicles suddenly accelerated without warning" caused the accident.

This report of NHTSA is also the only report in the world that has been published by the relevant functional departments of a national government and has legal effect on "Tesla is out of control".

Here, it is not simply to attribute all the nearly 20 Tesla accidents in China in the last year to the driver’s operational errors. The Rashomon discussion is still going on. NHTSA also said that the current investigation is only the end of the stage, and it is possible to launch a new investigation on Tesla in the future.

But this report is not without reference value. Maybe it can tell us what’s wrong with it.

Read this report of NHTSA carefully, and you will find that one word is repeatedly mentioned-pedal. In NHTSA’s targeted data analysis and scene re-inspection, the final conclusion of the problem is closely related to Tesla’s pedal.

Stepping on the wrong pedal is not a common problem for traditional cars, but for Tesla, this problem is infinitely magnified because of its unique "single pedal mode". Although this model is not original by Tesla, Tesla is a strong advocate of single pedal.

The so-called single pedal mode, that is, the start, acceleration, deceleration and stop of the vehicle can be controlled only by the pedal of the electric switch, and its principle is controlled by the forward current and reverse current of the motor.

In this mode, kinetic energy is recovered by reverse current, which can not only save electricity and improve the cruising range of electric vehicles, but also reduce the use of brakes, so that brake discs and brake pads have a longer service life.

The appearance of this mode has created a brand-new driving experience, and many skilled Tesla drivers can control the whole journey of the vehicle through the switch pedal.

Nowadays, this model is used in the products of major electric vehicle manufacturers, but the names are different. For example, in Xpeng Motors, this model is called X-Pedal model.

In practical use, this mode can completely replace the traditional braking mode as long as the driver keeps a good distance and a predetermined space. However, this mode cannot completely replace the brake pedal. Tesla clearly wrote this point in the user manual of Model 3, which is about kinetic energy recovery braking.

Single pedal mode creates a brand-new driving mode for electric vehicles, but it also embeds huge safety hazards. For skilled drivers, braking is not a stress reaction but a long-term muscle memory process, but the single pedal mode makes this muscle memory gradually disappear.

In single pedal mode, when the driver releases the switch pedal, the braking force brought by the reverse current is far less powerful than that provided by the brake disc and brake pad when the brake is slammed, which is why Tesla can’t cancel the brake pedal when designing the single pedal driving mode.

When users get used to the driving mode of single pedal, the muscle memory of the action of "braking" slowly changes from stepping on the brake pedal to lifting the electric pedal. After this habit becomes natural, when many drivers suddenly have an emergency in front of the vehicle, their first reaction is to release the pedal. When they find that the braking force is insufficient and realize that they have not taken compulsory braking measures, it is already too late to step on the brake pedal.

What’s more, when he realized that he should step on the brake pedal in a state of high mental tension, his muscle memory made him step on the accelerator pedal.

This may cause many Tesla owners to recall their own operations after the accident, thinking that they stepped on the brake pedal, but in fact they stepped on the electric pedal, causing the vehicle to "accelerate out of control for no reason" and eventually leading to traffic accidents.

Of course, the "whipping corpse" in the single pedal mode can’t perfectly explain the reasons for the 19 out-of-control cases of Tesla in China in the past year. We still hope that there will be official intervention to exonerate consumers or Tesla.
