  Nowadays, the automobile has entered the era of diversified development. A car product that is loved by consumers can have a lot of labels, such as high value, scientific and technological intelligence, humanization, multi-purpose and so on. These labels can also be changed and sublimated with the changes of the times and the development of automobiles, but I think that as a means of transportation, people’s pursuit of driving comfort will never change.

  When it comes to the driving comfort of cars, we have to mention the "chassis suspension" system, one of the three major parts that both oil cars and trams will have. In the chassis suspension system, the suspension system, as the only structure that connects the upper and lower car bodies, plays a vital role in its design and adjustment.

  In fact, among the global automobile brands, many well-known brands have made research and innovation on automobile suspension, such as the magic body of Mercedes-Benz, KDSS of Toyota and HBMC of Nissan. Their birth has greatly improved the driving stability and comfort of automobiles. So is there a brand or a technology in China that can reach or even surpass them? Then I think the answer is yes. It is the industry’s first new energy exclusive intelligent body control system-Yunqi.

  What is a cloud chariot?

  Everyone must remember the "dancing" U9 sports car at BYD Yunqi conference. It appeared in that way, which not only won the attention of the public, but also proved the strength of Yunqi intelligent body control system to the global automobile market.

  Yunqi is an intelligent car body control system developed by BYD Group for five years and costing billions of yuan. It includes Yunqi -C intelligent damping car body control system, Yunqi -A intelligent air car body control system and Yunqi -P intelligent hydraulic car body control system, covering the needs of different driving scenes such as home, sports, administration, off-road and entertainment. This time, we also experience the actual use feeling brought by different systems through the experience under various working conditions.

  Yunnian -C Intelligent Body Damping Control System

  If the intelligent body control system of Yunqi is classified, then Yunqi -C should be considered as a more popular and popular one. It is mounted on BYD Tang, BYD Han and BYD Song L just launched.

  The damping continuous variable adjustment function of Yunqi -C can solve the uncomfortable feeling of passengers in the car when the car is driving at high speed on a rough road or slightly bumping, and increase the comfort of the car. In the rough road, the system will increase the low-frequency damping through the cloud algorithm to stabilize the body posture when the vehicle is thrown up and down. To put it bluntly, it can avoid shaking like a boat and reduce the dizziness of passengers.

  When passing through the washboard road or the gravel road, the system will automatically adjust the damping of the shock absorber to be low, and at this time, the compression and stretching speed of the vehicle’s shock absorber will also be improved, so that it can respond and resolve the continuous high-frequency impact quickly. Commuting in the city will make the ride more comfortable.

  In this test drive, I also experienced the model Tengshi N8 equipped with Yunqi C intelligent body damping control system for a long time. Through the driving experience of high-speed, national roads and roads, the overall comfort performance brought to me is better than that of the same class without body damping control system. In addition to coping with the impact caused by falling and bumps on the vehicle, you can also feel the full lateral support of the vehicle when going up and down the ramp or turning quickly. The attitude of the vehicle and the lateral stability of passengers in the vehicle are very good, and with the comfortable parking function, this system is completely ok for daily use.

  Yunnian -A Intelligent Air Body Control System

  If Yunqi -C intelligent body damping control system only appears as a popularizer, then Yunqi -A intelligent air body control system can be regarded as a more advanced version, or a luxury benchmark for vehicle dynamic control. It realizes the dynamic adjustment of the body control through the precise sensing technology of Yunqi, the quick decision of Yunqi Intelligent Computing Center, the output of precise control strategy, and the control of air spring intake and exhaust, stiffness conversion valve, shock absorber solenoid valve, etc., so that the whole vehicle has the ultimate comfort, stability, support and passability. That is, with the addition of air spring, the vehicle equipped with Yunqi -A intelligent air body control system has become a necessary condition for you to have a higher-level and more interesting driving experience.

  Yunqi -A intelligent air body control system can be adapted according to different vehicle types, and the suspension adjustment stroke is as high as 150 mm. Vehicles equipped with Yunqi -A system can provide users with multiple modes including driving mode linkage suspension, welcome mode, convenient pick-up mode and high safety locking.

  The Yunqi -A intelligent air body control system also provides an electrically controlled shock absorber, which can realize stepless adaptive adjustment of damping. In addition to independently adjusting the appropriate body damping in different road conditions to ensure the driving stability of the vehicle, it can also alleviate the situation of braking and nodding when the vehicle starts, thus avoiding the dizziness caused by riding an electric vehicle. The vehicle roll angle speed can also be reduced by 23%. Simply speaking, when cornering at high speed, the vehicle side support force is more sufficient.

  This test drive is equipped with Yunnian -A intelligent air body control system. When passing through speed bumps and potholes, the overall suspension will give me a more resilient feeling, and the wheels will not bounce unnecessarily. When encountering potholes, bumps are basically not transmitted to the car, and when passing through, you can obviously feel that the integrity of the vehicle chassis and shock absorber is very good.

  On the mountain road with many bends, the vehicle’s roll is not big, which is related to shock absorption and steering in cooperation with the driving mode. In the sports mode, Tengshi N7 has good sports properties, and the directivity of the bend is good, and it is also silky when it turns quickly. The intelligent seat flanking function pioneered by Yunqi -A intelligent air body control system can quickly control the intelligent flanking seat according to the body posture change and steering signal. If the center of gravity of the vehicle turns to the right and it is cheaper to the left, the body will lean to the left, and then the intelligent seat flanking on the left will exert an opposite force on the body and actively support the side. This function can be used not only in sports driving, but also in low-speed off-road.

  Yunnian -P Intelligent Hydraulic Body Control System

  If Yunqi -C and Yunqi -A put more comfortable driving on the road, then Yunqi -P intelligent hydraulic body control system not only takes into account the road comfort, but also strengthens the off-road performance and balances the road and off-road working conditions.

  Through the precise sensing technology of Yunqi, and the quick decision-making of Yunqi Intelligent Computing Center, the control strategy is output, and the oil intake of shock absorber, damping regulating valve and stiffness regulating valve are controlled to realize the dynamic adjustment of body control. Yunqi -P is the world’s first intelligent hydraulic body control system, which integrates three core technologies: mechanical, hydraulic and electronic control. At present, it is mounted on the high-heat and equation Leopard 5 model.

  In the suspension part, the suspension adjustment stroke of Yunnian -P intelligent hydraulic body control system can reach 200mm, which can realize both four-wheel synchronous lifting capability and single-wheel independent lifting. The lifting force of the system is up to 5 tons, which meets the requirements of high-intensity off-road continuous lifting. At the same time, it provides multi-level height adjustment to realize various functions such as speed adjustment, convenient fetching, intelligent welcome and so on.

  Cross-axle working condition is one of the common working conditions in cross-country. If you want to pass smoothly, you must not only have strong locking function, but also have more tires to grip the ground, which is also an indispensable and important condition for getting out of trouble. Yunnian -P intelligent hydraulic body control system provides the function of "four-wheel linkage". When the vehicle is in a semi-unbalanced state with single wheel and diagonal wheel suspended, the four-wheel linkage function can transport oil for the suspended wheel shock absorber, lengthen the suspension stroke, improve the wheel contact with the ground and the sense of vehicle balance, and ensure the effective output of four-wheel power. The four-wheel linkage function of Yunqi -P can make the maximum wheel difference of the vehicle reach 620mm, and the tracking index RTI value of the whole vehicle can reach above 600 according to official data, which is the upstream level in non-modified mass production off-road vehicles.

  Camping is a hot outdoor activity nowadays. If the parking place is complex and uneven, and the vehicle tilts, it will affect the need for rest and entertainment in the car. At this time, the user can turn on the camping leveling mode. At this time, the vehicle will calculate the inclination angle through the attitude control module and adjust the body to a horizontal position several times. The adjustment range is about 100 mm. If it exceeds this adjustment range, the system can only try to ensure the balance of the car body.

  Do you usually encounter such a situation when driving? When a tall SUV body enters the basement, it is often blocked by a 2m height limit pole, which makes it impossible to enter the basement for parking, or when you encounter a lower bridge opening on the off-road road road, it will affect the whole trip. Aiming at this kind of working condition and user’s pain points, Yunqi -P intelligent hydraulic body control system provides "ultra-low mode". As long as you step on the brake pedal, in the mode with the lowest body height, the system will automatically enter the ultra-low mode by continuously pressing the height adjustment button for 7 seconds. At this time, the system will reduce the body height to 1.9 meters, and it can smoothly pass through the road section or closed space with height restrictions.

  Yunnian -P ultra-low mode

  Since there is an ultra-low mode, it must be an ultra-high mode. Contrary to the ultra-low mode, the ultra-high mode lifts the vehicle chassis by stretching the suspension, and it will be easier to pass through some high and unavoidable obstacles.

  The prospective cloud-chariot preview system in the future

  In the venue of this experience, we also saw a lookout U8 equipped with a cloud-based preview system. Yunqi preview system can respond quickly by identifying structured road surface and obstacles in front through lidar and binocular camera on the roof, and adjusting damping in linkage. It can output the road surface features and elevation curves within the range of 5-150m in front of the vehicle, and the recognition accuracy is 3 mm, and the recognition accuracy within 15m is over 99%. Of course, the technology is currently in the debugging stage, or it will be pushed and upgraded to users through OTA later. At present, only BYD is involved in this technology.

  Now the staff also demonstrated the practical application of the cloud-and-chariot preview system to us. After U8 recognizes the obstacle (log) at the center of gravity in the process of moving forward, the car body will slowly lift adaptively to increase the chassis passability, and the height of the car body will gradually return to the original height after passing.

  Full text summary:This time, we fully experienced BYD’s Yunqi -A, Yunqi -C and Yunqi -P intelligent body control technologies applied in different fields and models. Personally, I think this technology is at the leading level in China in terms of technology, market level and user level. After all, there are not many independent car companies that are vigorously involved in vehicle chassis shock absorption control, and BYD is at the forefront of the market.

  From the actual driving experience of these three sets of cloud technology, it is indeed better than the driving texture of the same class models, and the sports performance is also better. The most important thing is that BYD will bring down the altar such technologies as continuously variable damping technology and air spring technology, which were originally only carried in higher-priced models, so that more domestic users can experience high-level driving performance at lower prices. We should praise BYD for this.

[Look-there is a story on Friday] This is a question about choice and rights. Three women told their stories.

  July 11, 2019 is the 30th World Population Day, with the theme of "25th anniversary of the International Conference on Population and Development: accelerating the process and fulfilling the promise", which advocates making persistent efforts on the basis of the framework of the International Conference on Population and Development and raising awareness of how the choices and opportunities of girls and women have changed since the Conference.
  
  Twenty-five years ago, the Third International Conference on Population and Development was held in Cairo. More than 15,000 delegates from 182 countries and regions attended the conference. The Programme of Action adopted at the end of the conference made a commitment: "To formulate a new action agenda for empowering women to ensure their full participation in the social, economic and political life of their communities at all levels."
  
  The pursuit of rights and choices is a continuous process. Twenty-five years ago, due to the lack of contraceptives and economic and institutional obstacles, hundreds of millions of women could not enjoy the reproductive choices brought by contraceptives, and they could not choose whether to get pregnant, when to get pregnant, how often to get pregnant and who to get pregnant. Today, women’s social status has improved, and more and more women have truly realized their reproductive choices. They pay more attention to their personality independence and become an indispensable force to promote social development.
  
  "I’m glad I helped so many women."

  Tafta • Sharjah is one of the six women mentioned in the 2019 edition of the State of World Population Report. Her experience has witnessed the change of women’s rights in her country.
  
  Tafta • Sharjah is from Albania. When she was a teenager, she always wanted to go to university to study and become a doctor. However, due to various reasons, it did not happen. After graduating from high school, she attended a one-year course to train nursing midwives, which really changed her life track.
  
  After the training, Tafta was assigned to a remote village lacking medical facilities, medical personnel and medical supplies. Despite the difficult conditions, she is always full of enthusiasm for pre-natal care, delivery and baby care … … "I helped a lot of people, because many deliveries were carried out at home — — There were not so many medical centers at that time. I am very happy that I have helped so many women. "
  
  Tafta has two children. She bluntly said that if it weren’t for family economic reasons, she would have given birth to more. Later, when she was pregnant again, like the eastern European women of that era, she chose to have an abortion.
  
  The chaos in the early 1990s also had its positive side. A large number of Albanians have flooded into Italy and Greece and come into contact with new ideas and new ways of working and living. Tafta said: "We started to contact with another world and diverse perspectives. Before that, all we heard was the argument that everything outside Albania was bad."
  
  Now, life in Albania is improving, she said. She believes that her daughter and grandchildren will have more choices and opportunities. On the one hand, today’s contraceptives have been supplied free of charge on a large scale; On the other hand, her little daughter has become a police officer — — This fully reflects the changing of the old concept of gender equality.
  
  Tafta has been fighting cancer, and she is determined to watch her granddaughter grow up and stick to it. "I don’t want the tumor to take away my best things," she said. "As long as I have energy, I will try my best to help others."
  
  "In colleges and universities in China, I hope more students can participate in youth and healthy peer education."

  Young people provide endless creativity for social development, but with the early sexual maturity and the delay of marriage age, young people are facing the challenges brought by severe reproductive health problems. According to a national survey released in 2010, 22.4% of people aged 15-24 in China have had sex, and more than 20% of young women who have had premarital sex have experienced unwanted pregnancy. More than 50% of young people have unmet needs for reproductive health services to varying degrees. The reproductive health of young people is becoming one of the important factors affecting the healthy development of young people in China.
  
  Young people are more accustomed to getting knowledge about sexual and reproductive health from friends and classmates who have similar experiences and background knowledge. In mid-2004, a national youth organization — — China youth network was founded under the initiative and organization of China Family Planning Association (CFPA). It became the first youth volunteer organization in China to carry out peer education on sexual and reproductive health for young people aged 10-24 and advocate sexual and reproductive health and rights.
  
  He Shanshan, a student in Tsinghua University, is one of the core members of china youth network. She has been a volunteer for five years. When she was just a volunteer for adolescent health, He Shanshan encountered many difficulties. "Sometimes when we carry out activities at school, we will encounter situations where no one participates or the school does not support it. Some college students have misconceptions about sex and reproductive health. It is also difficult to change. I was impressed once when we talked about the specific use of condoms in a university. Some students stood up and slammed the door because they didn’t understand us. "
  
  When talking about people’s misunderstanding of sex education, He Shanshan said: "We advocate comprehensive sex education and provide suitable sex education for children of all ages from 5 to 18. For young people, not only talk about sex, but tell them how to know their bodies and deal with intimate relationships. Gender equality is equality between men and women, and men’s rights also need to be protected. We must break the stereotype of gender. "
  
  Speaking of the changes in these five years, He Shanshan said: "In the past, the content of sex education was to teach girls to say ‘ No ’ Now we are more telling girls how to protect themselves and communicate with their partners if they don’t want children or get sick. Every girl should have the right to choose the size of her family and the interval between giving birth to children, rather than becoming a fertility tool. "
  
  Last October, as a youth representative of the IPPF Asia Region, He Shanshan went to Kuala Lumpur to attend the regional council and met Joshua from Tonga, an Oceania island country. He was the representative of the last IPPF Asia Region, and He Shanshan took the baton from him. He brought good news. In June 2018, he was awarded the "Queen Young Leader Award" by Queen Elizabeth II. When Joshua was in high school, because his friends had suffered from sexually transmitted diseases, he realized that sexual and reproductive health was affecting the healthy lives of young people in Tonga, so he began to participate in the training of comprehensive sex education. Since then, he has been doing his best until he handed over the baton to He Shanshan. There are still many global youth health volunteers with similar experiences. They have been subtly influencing everyone around them with their understanding, care and sense of responsibility.
  
  "We not only represent the youth and the country, we are working hard for the whole cause, and the international environment is very friendly, which has always encouraged our young people to speak out." He Shanshan said.
  
  "Dance of Youth and Healthy Life" gathers the power of upward growth.

  Hu Lan (third from left) is at the event site.

  "How do women protect themselves in the face of partner pressure? Let me tell you a story that happened around me … …” In the auditorium of a factory in Longgang District, Shenzhen, a "Dance of Youth and Healthy Life" project is going to the "story sharing" link. The narrator of the story is Xiaoxue, a volunteer of the youth health project and a working girl who came to Shenzhen from Hunan.
  
  The lights gradually dimmed, and the crowd gradually became quiet. Everyone’s eyes were fixed on Xiaoxue. Xiaoxue’s thoughts returned to the unforgettable experience of her best girlfriend eight years ago with soft music: in her early twenties, at the best age of her life, Xiaoxue’s girlfriend suffered an unexpected pregnancy. Her so-called boyfriend chose to escape because he was at a loss. Xiaoxue accompanied her best friend to a small clinic and had an induced abortion. Less than a year later, the same situation was staged again. Because she was afraid of the eyes of the people around her, her best friend chose to go to a small clinic with poor medical and health conditions, and repeated surgical injuries caused great harm to her body and mind, which also laid a hidden danger for Xiaoxue’s best friend’s marriage and childbearing life.
  
  When the story was finished, the music stopped and the scene was quiet. Xiaoxue broke the silence: "At that time, we were very young, and no one taught us about sex. We didn’t know how to protect ourselves. The fluky psychology and partner pressure when getting along with close partners all caused great harm to many women like my best friend. After listening to the story, I believe everyone should have their own answers." This is a fragment of the "Dance of Youth and Healthy Life" project entering the factory to carry out activities.
  
  “‘ Dance of youth and healthy life ’ It is an international youth project jointly introduced to China by the China Family Planning Association and the United Nations Population Fund. It is a youth project with music and dance as the carrier, psychological model activities as the foundation, and sexual and reproductive health as the core of knowledge to guide young people to establish positive sexual concepts and attitudes towards life. " Hu Lan, the organizer of this activity, is the deputy stationmaster of Fuchengao Community Workstation in Pinghu Street, Longgang District, Shenzhen, and she is also the trainer of the international headquarters of the "Dance of Youth and Healthy Life" project. She told CCTV reporters that she is interpreting comprehensive education in a way that young people like, affecting not only women but also men.
  
  A factory doctor once took Hu Lan’s hand and said, "I really hope your activities can be carried out for a long time. There are too many female workers, and they need to strengthen their awareness of self-protection." Hu Lan said that some factory leaders hope to add the content of sex and reproductive health education to the induction training of new employees. She saw that more and more people in society realized the importance of sex education.
  
  The activities organized by Hu Lan not only entered the community factory, but also reached the middle school students. "In the past, when talking about gender topics in physical health classes in primary and secondary schools, teachers would say: ‘ Look at these two pages for yourself ’ . Now we have the opportunity to enter the school, not only to talk about knowledge points, but also to transmit an idea, which is welcomed by students. "
  
  In recent years, news such as "teenage pregnancy" and "children being sexually abused" have been exposed in the media. Parents and schools generally recognize the necessity of sex education, but there are still ambiguous attitudes about the way and degree of sex education, and even take evasive actions.
  
  At present, Hu Lan’s community still enters primary and secondary schools with short-term and decentralized themes, such as "welcoming adolescence", "preventing sexual harassment" and "staying away from AIDS", or carries out project activities in schools that are very supportive of project activities as a whole class.
  
  At the same time, Hu Lan also expressed his confusion. With the adjustment of the national population policy and the shift of the focus of local government work, the grassroots youth health education team is unstable. Many social workers can no longer engage in youth health education because of job adjustment, so they can only participate in it in their spare time.
  
  Take the area where Hu Lan is located as an example. In 2016, there were 225 young pioneers in Pinghu Street, Longgang District, Shenzhen for rotation training, and a core youth pioneer team of 30 people was formed to carry out youth health education activities in streets with a population of about 500,000. After the institutional adjustment, 80% of the staff are currently diverted to other departments. At present, only the members of the core team of the project are relatively stable, and the data is just a microcosm of the loss of local basic youth health education personnel. Although there is a constant inflow of fresh blood, the cost of time and technology has affected the development of youth health education.
  
  In sharp contrast to the sharp drop in personnel, schools, enterprises and community service centers that have conducted youth health education have a rising practical need for youth health education.
  
  As a person who has served in the front line of the community for a long time, Hu Lan and his colleagues have seen too many real cases. They carefully prepare and carry out every activity with enthusiasm and expectation. Instead of flowery words and many grand slogans, what they have is a heart full of sincerity and social responsibility. Hu Lan said that the children’s "seeking help" when they encounter troubles, the trust of community residents and the support of teachers and leaders who care about the cause of youth health education have all given them great motivation to work. "A single spark can start a prairie fire." Hu Lan said that she would like to be that little flame, hot and strong. (Text/Feng Songyi)
