Core tip: "I really don’t know that climbing over the guardrail is the tiger garden." Yesterday afternoon, Xiao Xu recalled the scene when the three brothers crossed the fence and mistakenly broke into the tiger garden, shaking their heads again and again. On the afternoon of the day before yesterday, the three men went to visit the Badaling Great Wall. When they went down the mountain, they took a shortcut and strayed into the Northeast Tiger Park in Badaling Wildlife World. Xiao Xu’s 18-year-old cousin Guo was killed by a Northeast Tiger.

　　　　(Reporter Gan Hao) "I really don’t know that climbing over the guardrail is a tiger garden." Yesterday afternoon, Xiao Xu recalled the scene when the three brothers crossed the fence and mistakenly broke into the tiger garden, shaking their heads again and again. On the afternoon of the day before yesterday, the three men went to visit the Badaling Great Wall. When they went down the mountain, they took a shortcut and strayed into the Northeast Tiger Park in Badaling Wildlife World. Xiao Xu’s 18-year-old cousin Guo was killed by a Northeast Tiger. Yesterday afternoon, the Northeast Tiger Park in Badaling Wildlife World was temporarily closed.

　　　　Unfortunately, the young man is under 18 years old.

　　　　Xiao Xu introduced that all three of them are from Xingtai, Hebei Province, and the other two are his brothers and cousins. They came to work in Beijing more than half a month ago, and their cousin Guo is not yet 18 years old. At noon the day before yesterday, the three of them went to visit the Badaling Great Wall.

　　　　At about four o’clock in the afternoon, the three men arrived at the highest crib of the Great Wall and prepared to go down the mountain. "After going back for more than three hours, I want to take a shortcut down the mountain." Xiao Xu said that it was getting late. At this moment, the three people just saw a short cut down the hill and buses passing by, so they decided to take this short cut.

　　　　"When I approached, I found that I was stopped by the iron net." Xiao Xu said that after crossing the three iron nets, "we wanted to go out along the path ahead, but we didn’t expect to see a big tiger when we walked 100 meters." Xiao Xu said that the tiger came out of the roadside Woods and kept staring at them, less than 10 meters away.

　　　　The young man was not breathing when he was rescued.

　　　　"I am completely embarrassed." Xiao Xu said that they immediately turned and fled, and the cousin fell at the end. He was thrown to the ground by the tiger without running a few steps. Xiao Xu and his brother ran a hundred meters away and turned over an iron gate more than three meters high. They couldn’t see their cousin because of the trees. A few minutes later, the staff drove a jeep to save the two.

　　　　Liu Yisen, deputy general manager of Wildlife World, said that when the incident occurred, the inspectors were driving by. "Seeing that the tiger is biting a man’s throat, the man has no response." Liu Yisen said that the staff immediately drove up to the biting tiger, forcing the tiger to let go and run away. Subsequently, the staff drove the tiger back to the pool and got off the bus and found that the bitten man had no breathing. After arriving at 120, the man was confirmed dead.

　　　　Yesterday afternoon, the Northeast Tiger Park in Badaling Wildlife World was temporarily closed. Other tiger parks such as Bengal tiger and animal parks such as bears and lions are open normally.

　　　　■ follow-up visit

　　　　Biting Siberian tigers are locked up.

　　　　Yesterday afternoon, the Northeast Tiger Park in Badaling Wildlife Park was temporarily closed, and neither tour buses nor self-driving cars were allowed to enter. "The biting tiger has been kept in solitary confinement." Liu Yisen, deputy general manager of Wildlife World, said that this is an adult Siberian tiger with a strong physique.

　　　　Another person in charge said that after the zoo is closed, all wild animals such as bears, tigers and lions will be driven back to the house due to feeding and safety problems. Considering saving resources, the inner power grid will be cut off and powered on the next day before the beast is released. The person in charge also said that the wild animals in the park are stocked, and in order to make the living conditions of the wild animals close to nature, live food feeding is carried out at intervals.

　　　　■ doubt

　　　　Three lines of defense failed to stop the intruder.

　　　　According to Liu Yisen, the Northeast Tiger Park is located on the west side of the entire wildlife park, and there is a section of the Badaling Great Wall winding northward nearby. There are Woods between the Great Wall and the zoo, and the staff call it a "no man’s land".

　　　　Liu Yisen said that in order to prevent animals from escaping and outsiders from entering, there are three fences in Badaling Wildlife World, and there are obvious warning signs hanging outside the guardrail: "Do not approach if there are wild animals inside". The outermost layer is a 2-meter-high steel guardrail, and the middle layer is a 3.6-meter-high wire fence, both of which are uncharged. The innermost layer is a 1-meter-high power grid, close to the protective net in the middle, and its instantaneous voltage can reach more than 7000 volts, mainly to prevent animals from leaving the park. At the beginning of March, the garden also inspected warning signs and protective nets, and found no problems.

　　　　Xiao Xu said that the three men only saw a wooden sign with a white background and a rusty iron sign on the outermost steel guardrail, which was not marked. At that time, they thought these three iron nets were to protect the Great Wall, so they crossed it. When they reached the third protective net, they found that the net was charged and went through one of the gaps.

　　　　Liu Yisen said that when the staff asked the two survivors that day, they said that they saw the warning signs, but they did not believe that there were really wild animals in the park. In the meantime, the staff also smelled alcohol on the two. In this regard, two survivors said that they had never drunk.

　　　　Our reporter Gan Hao

　　　　■ aftermath

　　　　Family members entered the scene and did not see the wounded tiger.

　　　　The person in charge of the park said that there were three guardrails in the animal park and obvious warning signs were hung, which was very unexpected.

　　　　After the incident the day before yesterday, Xiao Xu and his brother were temporarily placed in a hotel in Yanqing by the zoo. At 5 o’clock in the morning yesterday, the families of the deceased also rushed to Yanqing.

　　　　Yesterday morning, Xiao Xu and his uncle and other family members came to Badaling Wildlife Park and asked to go to the scene of the incident for identification. Under the arrangement of the garden, family members and others entered the Northeast Tiger Park, but no tigers were seen.

　　　　Yesterday, the two sides made a preliminary contact on compensation. At present, the two sides have not reached an agreement on the issue of liability. Because no agreement was reached on the determination of liability, the two sides failed to continue negotiations on the amount of compensation. The person in charge of the garden said that Xu ignored the warning and crossed the guardrail into the garden. "I should bear the corresponding responsibility."

Recently, Xia Yiping, CEO of Extreme Yue Automobile, was not surprisingly dead in an interview. He said that Huawei’s investment in smart driving is 10 billion, while Baidu’s investment in smart driving is 100 billion, which means that Baidu’s investment in smart driving is ten times that of Huawei. Of course, it is self-evident.

Many people are shocked by this news. Most people know that Baidu is really doing smart driving. A few people also know that Baidu has its own car. Of course, the car is also using Baidu’s solution. But it is estimated that not many people will think that Baidu’s investment will be greater than Huawei’s. After all, Huawei’s products are everywhere, and the market influence is huge. Baidu’s products are much rarer, and its influence is even more incomparable.

Baidu and Huawei, who is more intelligent in driving and who invests more? Let the Kung Fu car show you around.

(1) 100 billion investment is a bit empty?

Let’s take a look at the historical process of intellectual driving between the two sides, and then combine their R&D investment to see what the two companies have done in recent years.

Baidu’s intelligent driving research and development began in 2013. In this year, Baidu began to do open source projects and began to make autonomous driving solutions. From the perspective of "qualifications" alone, Baidu is indeed one of the earliest enterprises in China to do smart driving, which is basically synchronized with Tesla and Google abroad. In 2021, Baidu defined three directions for its own smart driving, namely, providing smart driving solutions to OEMs, building their own cars, and then developing and sharing unmanned vehicles.

According to the public financial report, from 2013 to 2023, Baidu’s total R&D investment was 167.2 billion. If 100 billion was invested in smart driving, it means that the R&D investment of smart driving accounted for 59.8% of Baidu’s R&D investment.

How can I put it? This data is not impossible. After all, most of the money earned by Baidu in recent years has really been invested in the two directions of smart driving and AI. However, considering Baidu’s own business, I personally think that the proportion of investment in smart driving alone should not exceed 50%. More than 50 billion may be there, and 100 billion feels a bit empty.

Huawei’s investment in smart driving is relatively clear. When Huawei’s new smart car solution brand "Gankun" was released in April this year, Jin Yuzhi, CEO of Huawei’s smart car solution BU, once introduced that the department was established in 2019, and the accumulated R&D investment in five years exceeded 30 billion (about 6 billion per year). This data is still relatively credible.

Of course, if you want to talk about Huawei’s R&D investment in other areas, such as big models and AI, it’s hard to say whether R&D funds are included in smart driving investment. Anyway, it’s a muddle.

However, at least one thing is certain. The investment of Huawei Smart Drive and Baidu Smart Drive should be in an order of magnitude, and it will never be as bad as ten times. Because Baidu started earlier, it is still possible to invest more.

(2) What is the difference in output?

Let’s just say that Baidu has really invested more. Next, let’s talk about output, and the difference between the two may be a bit big.

When Huawei first entered the field of intelligent driving, it put forward its own goals, hoping to be Bosch in the era of electrification and provide a full set of intelligent solutions for OEMs. However, the effect is not ideal, most enterprises hold a wait-and-see attitude, and the promotion is not smooth. So Huawei made a smart car selection project, that is, cooperated with the OEM, but Huawei defined the smart car and gave the core intelligent hardware and software.

After several years of development, Huawei has formed a complete set of industrial chains. Needless to say, intelligent driving technology, the system has developed to the third generation, supporting intelligent assisted driving in the whole scene and intelligent parking in the whole scene, and then it can realize intelligent driving from parking space to parking space. In order to better realize intelligent driving, Huawei has also built its own high-performance motor and a special Turing intelligent chassis, which can realize full-dimensional perception, 3D control and intelligent collaboration.

Let’s put it this way: even the old rivals want to purchase Huawei’s motors. Recently, the independent BU department has been valued at 115 billion, and major car companies are scrambling to invest. Huawei is even the first company to beat down the price of lidar. It can be said that Huawei’s investment in smart driving has been richly rewarded and it has its own intelligent industrial chain.

Baidu’s smart driving output is not satisfactory. Since 2015, Baidu has found a lot of well-known car companies such as Daimler, BMW, Ford and Volvo to cooperate. Many domestic cars have also "tested the water", but the effect is not obvious. Cars equipped with Baidu Zhijia are rarely publicized as their own "business cards".

One of the most famous is probably Weimar, who has been holding Baidu for a long time and hasn’t done it yet. In the end, Baidu couldn’t help but make a gathering, and there was basically no noise. Including now, it has been listed for half a year, and the highest monthly sales volume is only 1143 vehicles.

The only achievement that can be achieved is probably that the radish runs fast. However, in terms of completion, it still only supports getting on the bus at a specific location, and the coverage is limited. There is still a long way to go before it can truly replace the online car. The biggest advantage is that it is cheap, but this cheapness is actually based on the "capital operation" of Internet companies. I hope to achieve market monopoly, and then I will serve as a "platform". Didi and Meituan are all like this.

However, it is hard to say whether the radish will eventually become Didi, Meituan, or Xiaohuangche and Ruixing.

(3) Hardware companies and Internet companies are very different?

The difference between Baidu Smart Drive and Huawei Smart Drive is also the difference between two different companies to a large extent. Baidu is a typical Internet company, while Huawei is closer to a hardware company.

The characteristics of software companies are that they like to invest early, get high returns, and pursue a monopoly. Like Baidu, the earliest money was made by being a search engine. When Google withdraws from the China market, Baidu will become a monopoly. Since then, it has been making big profits, and on this basis, it has expanded the business of encyclopedia, knowledge, post bar and so on, forming a complete ecological circle.

But this has also led to a problem. Baidu lacks the ability to actually make products. Baidu has been doing smart driving for so many years. The car is from the main engine factory, the laser radar is from the supplier, the chip is from NVIDIA, and the smart card is also bought. Speaking of things that belong to Baidu, it is that set of algorithms.

Therefore, Baidu is very passive, and it can’t control how much the car sells. Baidu can’t form a monopoly in the field of smart driving, and its algorithm can’t sell at a unique high price. For so many years, Baidu’s smart driving business has been losing money. Even many engineers in the factory finally "ran away" with the main engine factory.

Huawei started out as a communication equipment. Although it also has Internet genes, it is closer to hardware companies. Therefore, we can see that every step Huawei takes will strengthen its strength. The car is defined by its own design, the laser radar is its own, the chip is its own, the power card is its own, the motor and chassis are also its own, and it can even be sold outside.

This has formed a virtuous circle, and the cost of Huawei’s smart driving is getting lower and lower, gradually flattening the R&D investment and forming a positive cycle. The worse news is that with Huawei becoming the representative of China Zhijia, Baidu’s investment for so many years will probably be wasted.

(4) Kung Fu is angry

Baidu really started to do smart driving earlier, and invested more probability than Huawei. However, from the perspective of "output", Huawei’s achievements are even more dazzling. The average transaction price of a model developed by Huawei like this exceeds 500,000, and the monthly sales volume is nearly 20,000 units. The monthly revenue of this car alone is in the hundreds of billions, and Baidu only envies it. Not to mention that Huawei BU is independent, and it can earn tens of billions just by selling shares.

In the final analysis, consumers still look at products, not how early you do it and how much you invest. If you spend more money, you will definitely do better. How can domestic cars surpass joint venture cars? The earning power is far from perfect. The same money depends on who can spend more on the cutting edge, which better reflects the ability of the enterprise. What do you think?

　　[car home Engine Disassembly] It’s human nature to like new things, and you won’t miss an important new car like brand-new (|). But I’m sorry, the new car hasn’t come on the market yet, and even the test drive report hasn’t been seen yet, but it doesn’t matter. Let’s take a look at the new 1.5T GDI engine on the new GS5 first.

● Basic information of engine

　　We noticed that the cylinder diameter/stroke ratio of GAC, a brand-new 1.5T GDI engine, has become smaller. This change of long stroke is helpful to improve the engine torque and make the engine respond better at low speed.

　　However, by comparing the power parameters of the three engines in the above table, we can intuitively see that the same 1.5T engine has different tuning and the maximum power/torque is different. Take the maximum horsepower as follows: Honda 177Ps＞ > Chuanqi 171Ps＞ > Great Wall 169Ps, but the maximum torque is reversed: Great Wall 285N·m＞ > Chuanqi 265ps. Chuanqi’s self-positioning in this "challenge" is quite clear. The setting of power parameters is not blindly adjusted upwards, but on the premise of ensuring power and torque, the output speed of maximum power is lowered and the output speed range of peak torque is widened.

　　Of course, Chuanqi 1.5T GDI engine, as one of the "three big parts" of the whole vehicle, is an important factor that many consumers consider before buying a car. This disassembly is more to help consumers clarify the advantages and disadvantages of Chuguangqi 1.5T GDI engine. AB: What is the difference (highlight) between Chuanqi GS5 1.5TG DI and GS4 1.5T engine in 2019? What gains can these highlights bring?

● What are the highlights of GAC’s 1.5T GDI compared with the previous 1.5T?

Highlight 1: change from manifold injection to in-cylinder direct injection

　　First of all, the biggest difference between this 1.5T GDI and GS4 1.5T engine lies in its name-GDI (in-cylinder direct injection). The most direct benefit of changing the fuel injection system from manifold injection to in-cylinder direct injection is that the engine power performance is improved and the harmful gases in the exhaust gas are relatively reduced. Moreover, we know that the first-tier cities in China will soon implement the more stringent national six emission standards. As a car company, GAC must be ahead of the policy, so this engine adopts in-cylinder direct injection technology to achieve the national six emission standards.

　　It is worth mentioning that "National VI" refers to a national policy standard for automobile exhaust emission. After the implementation of the "National VI" emission standard, it will be divided into two stages: "National VI A" and "National VI B", which will be implemented on July 1, 2020 and July 1, 2023 respectively. In some emission standards, "National VI B" is more than twice as strict as "National VI A" )

　　It is worth mentioning that with the help of turbocharger, a higher compression ratio means that the engine is more efficient, can improve more power performance, and saves more fuel, etc. After all, the working feature of direct injection engine is to directly inject fuel into the cylinder, and use the air flow in the cylinder and the fuel on the piston surface to achieve better atomization effect.

　　Direct injection engine has a good performance in working uniformity and performance under full load, and even the problem of working instability of cold car has been significantly improved. Of course, things are two-sided. While the engine enjoys the power improvement brought by high compression ratio, it is also a test for the fixation of high-pressure fuel rail and the fuel pump pressure of the fuel supply system.

　　The "dadada" sound of direct injection engine during fuel injection has always been a headache for engine NVH engineers. We can see their solutions on GAC 1.5T GDI this time:

　　When the engine is running in the compression stroke, the pressure in the cylinder is very large. For in-cylinder direct injection engines, ordinary fuel pumps can’t meet the demand. Another important feature of in-cylinder direct injection engine is that the fuel supply pressure of fuel pump is very high, so that gasoline can be effectively injected into the high-pressure combustion chamber.

　　Because of the combustion characteristics of gasoline, the compression ratio of ordinary engines can’t be designed too high, otherwise it is easy to knock, so most direct injection engines will divide the fuel injection process into two stages, that is, two injections. The GAC 1.5T GDI engine made a small breakthrough in fuel injection-The strategy of "three injections per cycle" is adopted under the specific working condition of "high load and low speed"(It can be understood that the fuel is injected three times per cycle only when the vehicle starts, and it is injected twice in other working conditions): The first-stage pre-injection (which occurs in the intake stroke and the crank angle is about 360°~180°CA) can take away a lot of heat in the cylinder under the action of gasoline volatilization, and reduce the cylinder temperature, so as to achieve a lower ignition angle, and to effectively suppress the probability of knocking and ensure stable combustion. The second and third main fuel injection (which occurs at the end of compression stroke and before power stroke, and the crank angle is about 0°CA) can bring higher exhaust temperature and accelerate the light-off of three-way catalyst.The advantage isTo achieve a rapid start, reduce engine emissions, meet the national six B emission standards, and reduce fuel consumption.

Highlight 2: Switch to exhaust gas turbocharger with lower inertia.

　　Although turbocharging technology is not a brand-new technology, it is the mainstream development direction to apply turbocharging technology to small displacement engines. Thanks to the ingenious design of turbine blades, the low inertia exhaust gas turbocharger provided by Borgwarner can take into account both high speed and high power and low speed and high torque.

Highlight 3: The three-way catalytic converter has added more precious metals.

　　Engineers have made a lot of efforts to purify the exhaust gas in order to make the exhaust gas from the 1.5T GDI engine meet the national sixth B emission regulations. The biggest highlight is the adoption of a brand-new three-way catalytic converter and the addition of more precious metals in the catalytic converter, thus reducing the light-off temperature to 270℃. What is the concept of 270℃? Let me give you an example for your reference: the light-off temperature of the three-way catalytic converter in the general national standard is 400℃, and the difference between them is 130℃.

　　The author jokingly said here: the exhaust gas discharged by an engine that can meet the national six B emission regulations should be cleaner than the air in many cities, right? Is that engine like a walking "air purifier"?

　　　　[XCAR Technology Original]

　　　　Since the day when the automobile was invented, a "bad guy" who followed the vehicle along with it also appeared at the same time, and that was noise. In order to give users the best driving experience, in the past decades or even hundreds of years, car manufacturers have been fighting the "bad guy" of noise endlessly.

　　　　Now, automobile manufacturers will adjust their vehicles through strict noise control standards to ensure that each vehicle can achieve a good level of noise and vibration suppression when leaving the factory. Recently, the author was lucky enough to participate in and experience the NVH test of Changan Auchan. In the test, I experienced Changan Automobile’s emphasis on the development of Auchan’s NVH. So what "magic weapons" did Changan Automobile use to control Auchan’s NVH? Let’s continue to look down.

1. What is NVH?

　　　　NVH is the abbreviation of Noise, Vibration and Harshness. Noise and vibration are easy to understand. To put it bluntly, the roughness of acoustic vibration is those uncomfortable feelings, such as harsh, roaring sound and uneven vibration. NVH is the core index to measure the comfort and quality of a car, and the feeling it brings to users is also the most direct.

　　　　According to statistics, four of the top 10 complaints of consumers about automobiles are about NVH, namely, engine noise, tire noise, wind noise and body noise. About one-third of the complaints of the whole vehicle are related to the NVH problem of vehicles, and nearly 20% of the research and development expenses of major car companies are spent on solving the NVH problem of vehicles.

　　　　It can be seen that NVH is very important for both the vehicle itself and the brand, because it can give consumers the most intuitive impression and directly affect consumers’ perception of the "texture" of the vehicle, so it is an important task for all car companies to develop NVH well. At present, NVH is mainly determined by these points: government regulations, customer requirements, company needs and technical capabilities, competing models.

　　　　At present, automobile sound control has gone through three development stages:

　　　　1. Reduce noise: solve the error state of NVH and reduce noise.

　　　　2. Sound quality control: make the sound comfortable, meet the requirements of specific customer groups, and the sound of the vehicle model is personalized.

　　　　3, sound quality DNA: the model is personalized and the brand voice is differentiated.

　　　　Through the above three stages, the transition from noise control to sound design has been realized.

Second, the control of Auchan NVH

　　　　The vehicle noise that we can hear is usually generated by the noise source and transmitted through the channel to reach our ears. Generally, noise sources and transmission channels are controlled to reduce noise. Simply put, this is the transmission of sound in physics, and noise reduction should be suppressed from the source and propagation.

　　　　Generally speaking, vehicle noise is mainly divided intoAir soundandStructural sound：

　　　　Air sound sources: engine radiation noise, air inlet noise, air outlet noise, tire radiation noise, etc.

　　　　Structural sound sources: engine vibration, exhaust hook vibration, chassis vibration, transmission bearing vibration and so on.

　　　　Two kinds of sound sources are transmitted through the car body, and the air sound source reaches our ears through the car body barrier and car body sound absorption; The structural sound source reaches our ears through the body structure, bracket and vibration isolator. These two kinds of sound sources are transmitted and attenuated to form the interior noise together.

　　　　After understanding the generation of noise, let’s see what anti-noise and vibration capabilities Auchan has. Auchan, as an MPV model with high hopes from Chang ‘an, naturally invested a lot in NVH. We found many NVH development achievements on Auchan’s car body.

　　　　In the overall design, Auchan has optimized the acoustic vibration transmission structure such as modeling, powertrain, car body and chassis suspension, so as to reduce the noise source and isolate the transmission of vibration and noise outside the car.

　　　　The first is engine noise suppression. Auchan’s 1.5L naturally aspirated engine has done a number of treatments in silence, including valves, fuel injectors, air intake systems, silent pulleys, etc., which reduced the engine noise at the source. According to official data, the idle noise value of Auchan is only 39 decibels.

　　　　Auchan soundproofed the engine to reduce the noise from being transmitted into the cab through the front wall, fender, hood and other channels. The composite sound insulation and absorption material is pasted under the hood, which can absorb and reduce the noise of the engine and suppress the vibration of the hood.

Nowadays, there are many kinds of cars, and all kinds of models are dazzling. At this time, we should proceed according to our own reality, and the right one is the best. Nowadays, the first thing for consumers to buy a car is to see whether this car is rich in configuration, and it is no exception to nature. As for the outstanding performance of the car, please read it together.

Let’s take a look at the appearance of Exploration 06. The front face of Exploration 06 has taken a young and fashionable route, which is very recognizable. Headlights are very in line with consumers’ aesthetics and outline a deep effect. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4500 mm * 1865 mm * 1680 mm. The car adopts fashionable and dynamic lines, and the car body looks very spirited. With large-sized thick-walled tires, smooth lines run through the whole car side. In the rear part, explore the overall shape of the 06 rear and the front of the car, and the taillights present a fashionable and sporty design style, which is neat and vivid.

When I came into the car, the interior looked very sedate and reflected the sense of design. The steering wheel of the car is very domineering, made of imitation leather, and its practicality and face value are not bad. Take a look at the central control panel, which is decorated with a 13.2-inch central control panel, making the interior design quite layered and elegant. The interior feels good. Let’s take a look at the dashboard and the seats. The dashboard design is remarkable and looks very individual. The car uses leather seats, which are wide and thick, and the overall comfort and wrapping are not bad.
