Extreme Challenge 5 Practicing Warm Heart Public Welfare, Wang Xun Assists Di Lizheba in Protecting Water Resources

Upload failed.

The ninth episode of the fifth season of "Extreme Challenge" was broadcast last night. Luo Zhixiang, Zhang Yixing, Wang Xun, Di Lizheba, Yue Yunpeng, and Lei Jiayin came to Lizhuang Town and embarked on a journey to find a water source in order to save the water shortage crisis of "Planet Maywater". In the program, Lei Jiayin "self-confidence of fans", "laughter and tears" flew together; Wang Xun assisted Di Lizheba, regardless of personal victory or loss in order to protect the water source. Through this virtual water crisis battle, Jituan called on everyone to protect water resources, so that the audience could entertain and provoke thinking.

At the same time, the program also continues to move forward on the road of adhering to public welfare, sending encouragement and care to the students of primary schools in the earthquake-stricken areas of Yibin. In addition, the program also jointly launched the "Yangtze River Walk" public welfare donation activity to help poor areas along the Yangtze River and post-disaster primary schools in Yibin build sun runways. As a warm "national variety show", "Extreme Challenge" uses practical actions to convey the spirit of "This is Love". 

Lei Jiayin’s "Confidence of Fans" laughs frequently online and won the title "The Most Beautiful Person"

In this episode, Lei Jiayin, who wanted to show his fists and feet, was repeatedly "besieged". He came to the ancient town from "Maywater Planet" to find water, and repeatedly bumped into the "dehydration tribe" C.T.O who wanted to stop them. Lei Jiayin, who had never won since the fifth season, immediately showed a strong "desire to survive". He first pretended to be pitiful to the C.T.O and asked them to let him go for the time being. Seeing that the C.T.O members had a little "compassion", he started to "please" while the iron was hot, and "Wang Zining, Brother Xue" blurted out and managed to escape. Lei Jiayin, who thought he was saved from being "hunted" by his "three-inch tongue", said proudly, "I solved all this with my wisdom". Immersed in joy, he was "out of control", and with the confidence of "they can’t bear to eliminate me", he volunteered to be the "bait" to lead out the C.T.O.

The self-inflated Lei Jiayin encountered the challenge of testing professional skills – instant tears. With his solid acting skills and the stimulation of onions, his eyes were red in less than a few seconds, and he shed tears, helping Di Lizheba complete the task of obtaining "the tears of the most beautiful person", and also won the title of "the most beautiful person". Lei Jiayin, who burst into tears online, brought many "sources of happiness" to the audience.

Wang Xun assisted Di Lizheba in protecting the water source and winning praise from netizens

In this issue, Wang Xun was much more experienced and calm, and made a calm judgment on the performance of the other members one by one. Based on his years of understanding of Luo Zhixiang and Zhang Yixing, as well as subtle observations, Wang Xun determined that Luo Zhixiang’s self-destruction of his identity as an "infected person" was to "lose the car and protect the commander"; from the fact that Zhang Yixing did not take the initiative to "attack" Luo Zhixiang, it was determined that Zhang Yixing had been "infected".

Not only that, Wang Xun, who had a clear idea throughout the whole process, always insisted on saving the "planet" as the top priority. At the end of the show, Di Lizheba was the only one left who was not "infected". As an "infected person", Wang Xun should have let his team win. However, he chose to let Di Lizheba enter the spaceship by himself, successfully protecting the water source, and finally bringing "Planet Maywater" back to life. Wang Xun’s actions regardless of personal victory or loss made netizens praise, "Brother Xun is really warm!" 

"Extreme Challenge" calls for the protection of water resources "Yangtze River Tour" to practice public welfare and offer love to disaster areas

Water is the source of life, and water resources are the primary condition for maintaining the sustainable development of the earth’s ecological environment. This issue shows the process of the extremely challenging group going to the earth to find water through the virtual "Maywater Planet" water shortage crisis. In the end, in order to save their homeland, they gave up the opportunity to "go home" and worked together to deliver water, successfully bringing the "planet" back to life. Through the mission part of the show, the extremely challenging group made the audience entertaining and aware of the importance of protecting water resources. As the director said at the end of the show, "The water of the Yangtze River nourishes thousands of people who develop along the river. Without water, there would be no one. As long as everyone cares about water, today’s fictional game will not become a reality.

In addition to calling on everyone to be environmentally friendly, "Extreme Challenge" also does not forget to use practical actions to convey the power of public welfare. On the evening of June 17, a magnitude 6.0 earthquake occurred in Changning County, Yibin City, near the town of Lizhuang where the program was recorded. Soon after, the program team rushed to the disaster area of Yibin to visit the students of Shuanghe Town Central Primary School in Changning County, Yibin, where the epicenter was severely damaged, and sent encouragement and care to the students after the disaster.

At the same time, the program also jointly launched the "Yangtze River Walk" public welfare donation activity with the China Foundation for Poverty Alleviation and Alibaba Public Welfare. This activity aims to mobilize the whole society to build a sun runway for poverty-stricken areas along the Yangtze River and post-disaster primary schools in Yibin City through online donations from netizens, and contribute to the reconstruction of the disaster area. From sending warmth to the disaster area to launching a public welfare activity of love, "Extreme Challenge" uses practical actions to convey the power of "this is love".

When the body control system has a sense of autonomy, a comprehensive analysis of BYD Yunqi

ChatGPT was born, which triggered a global hot discussion and thinking. In just a few weeks, people both lamented the rapid development of artificial intelligence and were shocked by the great changes brought by new technologies to life and production, as if suddenly, computers really had self-awareness.

Artificial intelligence, as a substitute for human labor force, is only the tip of the iceberg. What kind of changes can be imagined when ChatGPT is applied to the automobile field? At present, technology has developed to pre-process the influence of each terrain and road condition on the car body, so as to adjust the suspension in advance to improve comfort, handling and safety, but most of them are limited to high-end models of luxury brands and have not been systematically popularized. However, with the release of BYD Yunqi Intelligent Body Control System on April 10th, this situation will be completely changed. From passive suspension to active suspension to intelligent body control, the awareness of body is awakening.

First, create the highest level of global body control system. 

BYD Yunqi System is the industry’s first exclusive intelligent body control system for new energy. The full name of Yunqi is Yunqi intelligent adaptive body control system, which is an intelligent body control system developed by BYD for five years and costing billions of dollars. Including Yunqi -C intelligent damping body control system, Yunqi -A intelligent air body control system, Yunqi -P intelligent hydraulic body control system and unlimited Yunqi -X control system.

Yunqi represents the highest level of the global body control system, which brings subversive improvement to new energy vehicles of BYD Auto’s brands, covering different use scenarios such as home, sports, administration and off-road, and creating an all-round and luxurious driving experience for users. When the new energy vehicle has no traditional engine and gearbox, the impact of chassis technology on the driving experience of the whole vehicle will be further amplified, so the brand of electric vehicle has higher and higher requirements for chassis and suspension. Independent research and development is costly and time-consuming, and it is usually unbearable for brands with poor product matrix, which leads most car companies to choose outsourcing chassis technology, which is easily affected by technical bottlenecks and soaring costs.

Second, from perception to decision-making to implementation, break the monopoly of foreign car companies in one fell swoop.

Electrification has brought about the transformation of the whole vehicle architecture, and the vehicle control has changed from mechanical control to electrical signal control, and the accuracy, efficiency and intelligence have been greatly improved. The body control system, which integrates software and hardware technologies such as perception, decision-making, control and interaction, can not only surpass the past, but also provide rich car scenes. This is the intelligent body control system of Yunqi, and the following three levels are the core of Yunqi technology.

Perception is the premise of cloud chariot.

The first key problem of Yunqi is road perception technology, which is the first step to realize intelligent body control. The preview system deeply integrates multiple road surface sensing elements such as monocular/binocular cameras and laser radar to identify road surface features and elevation curves within the range of 5-150m in front of the vehicle, and the recognition accuracy is as high as 3 mm, and the recognition accuracy is over 99% within 15m. It not only realizes the functions of road surface recognition and all-terrain monitoring, but also can quickly adjust and adapt with the suspension system.

Accurate decision-making is the key to Yunqi.

After mastering the core technologies such as software architecture, strategy formulation, algorithm design, etc., BYD’s self-developed Yunqi Intelligent Computing Center has multi-core and efficient processing capability, supports multi-signal interfaces, and can drive various actuators. Through cloud computing, it can process information such as road state, body posture and wheel load, and output the best control strategy in real time.

Take high-speed cornering as an example. Usually, the center of gravity of the vehicle will tilt to the inside of the corner, thus reducing the comfort and handling performance. Yunbi can automatically adjust the suspension located inside the corner, reduce the movement frequency by increasing damping, and achieve the purpose of hardening the suspension. From the completion of road preview, to intelligent decision-making and implementation, Yunqi Supercomputing Center has realized highly centralized integrated control.

Efficient execution is the guarantee of Yunqi.

For the implementation level of Yunqi, BYD independently developed and controlled the whole process through structural design, performance simulation, test methods and other aspects, and combined with the full-stack self-research of system software, it can achieve the perfect adaptation effect of suspension software and hardware. Yunqi intelligent adaptive body control system achieves millisecond response adjustment from the state identification of sensing parts, to the information processing decision of Yunqi Supercomputing Center, and then to the control execution of the whole vehicle.

In addition, users can also control the suspension height and damping mode through the voice control or manual adjustment interface at the APP end of the mobile phone and the Pad end of the vehicle, thus gaining more fun.

Third, "devolve" luxury and make "value" upward.

Next, we interpret Yunqi -C, Yunqi -A and Yunqi -P respectively to see what contribution they have made to chassis awareness.

Yunnian -C intelligent damping body control system-popularization of technology, entering the homes of ordinary people.

Yunqi -C is the first active suspension product in China to realize full-stack self-research in system design, calculation, modeling, simulation, matching and adjustment. The system architecture includes key components such as perception component, decision component and execution component. The suspension system of Yunqi -C can actively control the electronically controlled shock absorber according to the road condition information, and the damping can be adjusted steplessly, which mainly serves the comfort and sports modes.

When the vehicle passes through the bumpy road, the comfort control strategy of high frequency and small damping is adopted to make the chassis "soft", which can effectively buffer the road excitation input and quickly restrain the vertical movement of the car body. Under the condition of 60km/h continuous vibration road surface, Yunqi -C can help the whole vehicle achieve 96% vibration isolation rate, which greatly improves the comfort compared with the traditional suspension. The roll speed of 100km/h double lane can also be reduced by 39.7%.

Yunqi -C is mainly used to improve daily driving comfort and handling performance, such as body pitch, corner roll and steering angle at medium and high speed, etc. This is a popular version of product matrix. At present, more than 80,000 vehicles have been loaded on BYD Han EV, Tang and Tengshi D9, and the product experience has been well received by the market. Later, it was officially upgraded to Yunqi -C through OTA software.

Yunnian -A Intelligent Air Body Control System-Breaking the monopoly, luxury and comfort are no longer far away. 

Yunqi -A intelligent air body control system is the first suspension product in the world to realize full-stack self-research in system design and calculation, simulation selection, function and strategy development, software algorithm development and integration, matching and adjustment technology and key parts design. The system architecture includes sensing, decision-making, execution components, and key components such as adjustment part. Its biggest highlight lies in the high integration of three adaptive adjustments of suspension height, spring stiffness and damping hardness with the adaptive adjustment function of dynamic embracing seat, which is of pioneering significance in the industry.

The total lifting stroke of Yunqi -A can reach up to 150mm, which can restrain the acceleration of the car body and brake pitching by more than 25%, and provide two modes of manual and automatic adjustment. In addition, the suspension height is adjusted adaptively with the change of vehicle speed.

BYD also creatively integrated the self-adaptive adjustment function of the dynamic embracing seat into Yunnian-A. In order to suppress the inertia deviation caused by the roll of the vehicle when cornering at high speed, the dynamic embracing seat provides airbag support at the waist of the seat, so that the user can maintain a good driving posture and ensure the safety and comfort of high-speed driving. According to the news of the press conference, Yunnian -A will be the first to ride on Tengshi N7.

Yunnian -P intelligent hydraulic body control system-the world’s first new energy, providing a strong off-road gas field.

Yunqi -P is the world’s first new energy exclusive intelligent hydraulic body control system developed by BYD. It efficiently integrates three core subsystems, namely mechanical, hydraulic and electronic control. The system architecture includes sensing components, decision-making components and more complex execution components. It has the functions of one-button leveling, single-wheel lifting, four-wheel linkage, simultaneous adjustment of height, stiffness and damping. The working environment covers -40℃ to 85℃, with an altitude of 6000m, which is suitable for extreme and harsh environments such as high temperature, cold, high humidity and high corrosion.

The biggest difference between Yunqi -C and Yunqi -A is that Yunqi -P can stably bear the sprung load weighing up to 5 tons. It is an intelligent hydraulic body control system with the maximum load-bearing capacity for new energy passenger cars among the active suspension products released in the industry. In addition, Yunqi -P has a wide range of suspension height active adjustment and four-wheel linkage capabilities. The total adjustment stroke of the front suspension and the rear suspension is 200 mm. When facing off-road scenes such as bullet holes and cross shafts, all four wheels can touch the ground as much as possible to provide sufficient tire grip and balance. And when camping on uneven ground, the four-wheel suspension can be lifted independently to keep the car body level.

As BYD’s first million-class luxury car, I hope U8 will not only surpass the predecessors of traditional SUVs, but also bring the safety, comfort and intelligence of intelligent chassis, and also bring the luxurious and comfortable feeling of integrating technology, new energy and new platform, covering all kinds of car scenes such as transportation, off-road, leisure and business.

To sum up, three different intelligent car body control systems actually correspond to three different consumption and car use scenarios, and the significance of cost performance and popularization brought by Cloud -C; Yunqi -A Active Road Perception and Advanced Air Suspension: Yunqi -P’s cross-era off-road innovation makes users feel the significance of intelligent body awakening from different levels of high school, middle school and low school.

Fourth, the autonomy of production equipment to software and hardware is the core of cloud technology.

From the perspective of global automotive technology, in addition to Rolls-Royce, there are three intelligent body control systems familiar to domestic consumers, namely, the magic body control system applied by Mercedes-Benz in GLE, the magic carpet intelligent air suspension of BMW 7 Series and Audi A8L active suspension technology.

BYD’s cloud technology not only fills the last short board on the traditional chassis, but also combines the pre-control with the wire-controlled chassis, creating a new integrated technology of vertical integration and realizing the straight-line overtaking of traditional car companies and new forces.

The core components of Yunqi released by BYD this time, such as compressors, distribution valves, testing instruments and so on, are all developed and produced by BYD, and the product matrix is subdivided into Yunpan -C, Yunqi -A and Yunqi -P, which comprehensively covers all civilian use scenarios to correspond to different models and consumer demands respectively. This chess game can be said to make opponents dream of it.

Five, R&D investment broke 20 billion, BYD technology is king.

Although the active body control system is not new, the whole technology of Yunqi is self-developed by BYD, which not only gets rid of the dependence of domestic brands on parts suppliers, but also realizes the independence of core technologies, which is the most admirable place. Especially when this system is endowed with perception layer and decision-making layer, the "self-awakening" suspension will bring us unprecedented experience and fun.

In order to increase its core competitiveness, BYD has made great efforts in technical input and output in recent years. In 2022, the accumulated R&D investment was 20.223 billion yuan, up 90.31% year-on-year. By the end of 2022, BYD had applied for more than 39,000 patents and authorized more than 28,000 patents worldwide, with nearly 70,000 R&D personnel. Under the research and development and investment at any cost, the peak technologies such as blade battery, DM-i super hybrid, E platform 3.0, CTB battery body integration and "Easy Sifang" have been released one after another, and the emergence of Yunqi has enabled BYD to keep ahead in technology, and at the same time, it has provided consumers with the best choice, no longer subject to the serious premium of joint ventures or imported cars, and truly fulfilled the significance of technology changing their lives.

Volvo just bought half a month’s car paint, and it bulges in many places. 4S shop: The reason has not been found out yet.

  Half a month after the arrival of the new car with a price of 360,000 yuan, there were many bulges in the paint of the whole car. Recently, Ms. Yang, the owner of Suzhou, was caught in a long dispute because of the quality problem of the new car. She told The Paper that after the incident, the 4S shop tested the car many times, and the test results changed again and again. So far, an authoritative test report has not been given, and she asked the 4S shop to return the car, which was also rejected.

  In this regard, on November 19, a relevant person in charge of Suzhou Zhongsheng Wohao Automobile Sales Co., Ltd., a 4S shop involved, said that the reason for the bulging of automobile paint has not yet been ascertained, but according to the national automobile three-guarantee policy, it has not yet reached the standard of returning cars, and only the bulging position of automobiles can be repaired.

  The staff of Volvo Car Customer Service Center didn’t respond to the quality problem of car paint, saying that if there is a problem with the car, the customer needs to negotiate with the dealer to solve it. Whether to return the car or not will be judged according to the national car three-guarantee policy and process.

  There is a quality problem in picking up the car for half a month, and the change of car is rejected.

  In August this year, Ms. Yang bought a new Volvo xc60 car in Suzhou Zhongsheng Wohao Automobile Sales 4S Store, and the landing price was about 360,000 yuan. However, half a month after picking up the car, Ms. Yang found that there was a problem with the car paint. "First, there was a bulge in some parts of the car. At that time, I thought it was glued, so I didn’t care much."

The small drum bag appeared in the car. The pictures in this article are provided by the respondents.

  The real problem was found at the end of September this year, when Ms. Yang sent her new car to a car wash shop for cleaning. She told The Paper that during the cleaning, the car wash master told her in confusion, "This car looks like a new car. Why are there so many bulges on the body?" Under the reminder of the car wash master, Ms. Yang found that those places that looked like "sticky dirt" were originally small bags that were raised one by one. These small bags appeared in many places in the whole car, and some small bags were densely connected together, making the car look like "acne" and the surface was uneven.

There are hundreds of bulges in the whole car paint.

  There are hundreds of bulges in the whole car paint.

  A mechanic told The Paper that the problem of bulging of automobile paint surface generally appeared in older cars. "For example, if the primer was sprayed with topcoat before it was dry, such a problem would easily occur. However, the new car has not been seen before, and the painting of the new car before leaving the factory is computerized, which is unlikely to happen. " He said that if the bulging problem is not dealt with in time, the area will gradually expand, which may eventually lead to the paint falling off in many places.

  At the beginning of October, Ms. Yang drove the car to Suzhou Zhongsheng Wohao Automobile Sales and Sales 4S shop for testing. She told The Paper that the technicians polished the bulging parts of many car paints, and did not solve the problem of bulging. "At that time, the technicians said that this was not an external (paint) problem, but an internal problem."

  Ms. Yang said that she asked for a car change on the spot, and the 4S shop also said that it would not shirk its responsibility. In the live recording provided by Ms. Yang, it can be heard that the staff of the 4S store said that "they will not shirk their responsibilities". In the recording, Ms. Yang’s lover mentioned that "these points are bulging from the inside, and now they are all cobwebs". The staff of the 4S store also agreed and repeatedly admitted that they can take responsibility on behalf of the manufacturers.

  At the end of October, the 4S shop contacted Ms. Yang again to test the car to determine whether the car was self-painted. Ms. Yang said that after the on-site painter’s appraisal, it was determined that the car had no traces of self-painting. "At that time, we also put forward the demand of changing cars. The 4S shop said that it would bear the responsibility, but we still need to wait for the appraisal results of Volvo manufacturers."

  At the end of November, under the remote guidance of Volvo factory technicians, the 4S shop tested the car for the third time. "The manufacturer first asked for polishing to see if these bulges were stuck on it, but polishing did not solve the problem. On the spot, the staff of the 4S shop repeatedly told the manufacturer that this was an internal problem, not an external one." Ms. Yang said that after the polishing failed, the manufacturer’s technicians proposed to cut the paint surface of the bulging part for inspection. However, after cutting the bulging part to the white metal layer, there were still problems. "At that time, the technicians of the 4S shop told us that there was a problem with the primer, which led to the bulging of the paint surface. If there is a problem with the primer, it can be said that the problem lies before the car leaves the factory. "

  Ms. Yang told The Paper that the staff of the on-site 4S shop said that the test report issued by Volvo manufacturers would be available the next day after the test, and the solution would be determined according to the test report. However, since then, Ms. Yang has repeatedly urged that the 4S store always responded with "the manufacturer has not provided it yet, and we will follow up".

  On November 16, Ms. Yang called the 4S shop again, and the staff gave the manufacturer’s test conclusion orally. According to the telephone recording provided by Ms. Yang, the staff of the 4S shop said: "Now the analysis is that both the tail and the fender of the car have bulging problems, but the tail and the fender are not painted by a supplier, and both of them have problems. It is initially determined that it is caused by the external environment, not the paint itself."

  This statement made Ms. Yang unacceptable. "After checking for more than a month, the master had already said that there was a problem with the primer. Now, not only did she fail to give a qualitative reason, but she also shirked the responsibility to the external environment?" In addition, Ms. Yang said that she had repeatedly asked for a test report, but none of the 4S stores could provide it.

  4S shop: Why did the car paint bulge appear? The reason has not been found out yet.

  In view of the above situation, on November 19th, The Paper contacted Suzhou Zhongsheng Wohao Automobile Sales 4S Store, and a relevant person in charge of the store said that the specific reason for the problem of Ms. Yang’s car has not been found out yet. "There has never been a problem of new car paint bulging before, and we are now investigating with manufacturers whether it is a production line problem or a paint surface corrosion pollution."

  The person in charge said that in the previous testing process, 4S shop technicians pointed out that it was a problem of primer coating. This was a personal judgment made by the technicians and could not be used as a qualitative reason. Only the testing report issued by the manufacturer could be used as an authoritative report. He said that the reason why the test report was not provided to Ms. Yang was because she was going through the stamping process and could show it after the stamping. If Ms. Yang could not accept the test results at that time, the 4S shop agreed to have the vehicle tested by the Quality Supervision Bureau.

  At present, the 4S store thinks that Ms. Yang’s request for car replacement can’t be satisfied, and said that she has never promised Ms. Yang’s request for car replacement before. "We can deal with the bulging place of the car and let the car drive beautifully on the road, but if it is required to return the car, it has not yet reached the requirements for car replacement in the three-guarantee policy of the car, and we can’t return the car."

  Regarding the 4S shop’s statement, Ms. Yang insisted that she only accepted changing cars or returning cars. "Our new car has problems for half a month. Now there are more than 100 bulging places in the car, which are polished and cut. It is completely unrecognizable. Even if it is painted, the new car looks like a used car." Ms. Yang believes that the problem of bulging is obviously the quality problem of the car itself.

  Is the new car paint bulge a quality defect of the vehicle? The reporter from The Paper called Volvo Car Customer Service Center for many times, but the staff who contacted for many times did not respond for reasons such as "feedback to relevant departments" and "no authority to express their views". Regarding Ms. Yang’s request for car replacement, the staff said that the dealer is a window for direct customer service on behalf of the manufacturer. It is suggested that customers negotiate with the dealer, and whether to return the car or not will be judged according to the national three-guarantee policy and process.

  On November 20th, the reporter from The Paper inquired about the Quality Control Section of Wuzhong District Market Supervision Administration, Suzhou. The staff of this section said that the quality problems of automobiles can be solved according to the automobile three guarantees policy. Regarding the quality problems of the new car proposed by Ms. Yang, the staff said that they would arrange quality inspectors to conduct an investigation and then give a response after the investigation.
