The poor working environment, unfair treatment, low salary and so on of those workers need to attract social attention. The real cost behind cheap fashion is beyond our affordability.

Some edema comes from heart disease? There are many reasons for edema of lower limbs, so we should be vigilant.

  Li yonglei

  For "edema", most people will recognize it. The simplest way is to press the affected area with your hand. If the skin sags into a small pit and cannot recover immediately, it is "swollen". After living at home for more than two months, many middle-aged and elderly people have similar edema. What needs to be vigilant is that the causes of edema are not only the obvious reduction of exercise and the high age of the family, but also some pathological reasons may be hidden.

  Clinically, "edema" generally refers to edema of lower limbs, mainly manifested as swelling of limbs, which starts at the ankle and then spreads to the whole lower limbs, and sometimes occurs in the limbs, but edema of lower limbs is the most common.

  Why does kidney disease cause edema?

  Mr. Ma has always felt weak waist recently, and his urine is dark and frothy. When he took off his socks, he found obvious indentation on his calf. After seeing a doctor, he was diagnosed with hematuria, proteinuria, moderate hypertension and other problems, and was later diagnosed as acute glomerulonephritis. The edema in the patient’s leg is the secondary edema caused by renal disease.

  Edema can be caused by many reasons, and different edema has different characteristics. Edema caused by kidney diseases is called nephrogenic edema. Nephrogenic edema is the most common cause of edema in clinic, and it is also one of the common symptoms of kidney diseases. Why can kidney problems lead to edema? There are two main reasons: first, the filtration function of glomerulus to water and sodium decreases, while the renal tubule reabsorbs water and sodium well, which leads to the retention of water and sodium, which is often accompanied by the increase of capillary permeability in the whole body, so the water in the interstitial space is retained; Second, a large amount of proteinuria in the body leads to low plasma protein.

  Nephrogenic edema first occurs in loose tissues, such as ankles, eyelids or face, which is most obvious in the morning and can spread to lower limbs and the whole body in severe cases. It is characterized by being soft and easy to move, showing concave edema in clinic, that is, depression can occur when pressing local skin with fingers.

  Clinically, nephrogenic edema is mainly divided into nephrotic edema and nephritis edema.

  Nephrotic edema mainly refers to nephrotic syndrome. In addition to systemic edema, patients also have a lot of proteinuria, hypoproteinemia and hyperlipidemia. All causes of nephrotic syndrome, including primary causes (minimal change nephropathy, mesangial proliferative glomerulonephritis, mesangial capillary glomerulonephritis, membranous nephropathy, focal segmental glomerulosclerosis) and secondary causes (allergic purpura, systemic lupus erythematosus, hepatitis B virus-associated nephritis, diabetic nephropathy, renal amyloidosis, myeloma nephropathy) can cause nephrotic edema.

  Nephritis edema mostly starts from eyelid and face, mainly seen in patients with acute glomerulonephritis. In addition to edema and hypertension, the patient’s clinical manifestations are also urine changes, such as hematuria, proteinuria, red blood cell cast, oliguria, etc. After the acute phase, the edema can subside.

  For such patients, early treatment is the key, and the overall treatment principles are as follows:

  1. Restrict sodium salt intake: Both nephrotic edema and nephritis edema have sodium and water retention, so sodium salt intake must be restricted, but it should be appropriate to avoid hyponatremia;

  2, diuresis: when necessary, using diuretics while limiting sodium can promote sodium and water discharge to relieve edema, and can relieve hypertension and reduce heart load;

  3, control proteinuria: proteinuria must be controlled for nephrotic edema, and immunosuppressive drugs (dexamethasone, prednisone, etc.) can be used to restore the normal permeability of glomerulus;

  4, under the guidance of a doctor, supplement plasma protein.

  Some edema comes from heart disease.

  Ms. Liu, 75, has a history of hypertension for many years, but she believes that she is in good health and does not take medicine regularly. After catching a cold two weeks ago, I felt weak, palpitation, obvious swelling of my feet, and it was difficult to wear shoes. After coming to the hospital, he was diagnosed as hypertension, coronary heart disease and heart failure by the Department of Cardiology.

  Ms. Liu, a patient with hypertension, suffered from heart disease and heart failure after catching a cold. It is due to the edema of lung congestion tissue, the increase of airway resistance and the decrease of alveolar elasticity, resulting in dyspnea, which is to say that breathing is fast and shallow. In fact, clinically, most hypertension will be combined with various types of heart disease, and at the same time, different stages of heart disease may be accompanied by different degrees of hypertension. Poor long-term control of hypertension can cause changes in heart structure and function, which is called hypertensive heart disease. Studies have shown that 70% of heart failure is caused by hypertension, and there may be related cardiac complications such as coronary heart disease and atrial fibrillation. In the early days, patients are prone to fatigue dyspnea, such as when going upstairs, carrying loads, buying food, and even when looking after children. Some people will have paroxysmal dyspnea at night, which usually occurs 1-2 hours after falling asleep. Patients wake up because of tightness and shortness of breath, and may have cough and foam-like sputum. Those with mild symptoms can relieve themselves and live as usual during the day, while those with severe symptoms can continue to attack and cough pink foam-like sputum.

  Then, how is edema related to high blood pressure and heart disease?

  Recently, many patients who came to the hospital due to edema of lower limbs were admitted to the clinic, and some of them were diagnosed as cardiogenic edema. Cardiogenic edema is the body edema caused by cardiac dysfunction. The disease can present systemic or localized edema, which first manifests as decreased urine volume, heavy limbs and increased weight, and then gradually appears edema of lower limbs and whole body. Under normal circumstances, the patient’s ankle first appears sunken edema, which gradually develops into systemic edema. Accompanied by right heart failure, patients will also have other symptoms and signs, such as palpitation, asthma, jugular vein distension, hepatomegaly, and even pleural effusion and ascites. The principles of treating cardiogenic edema are cardiotonic, diuretic and heart protection.

  In heart diseases, heart failure is the most common cause of limb edema. Due to the different concentrations of protein and salt in blood and surrounding tissues, when blood circulation is blocked, the surrounding tissues can easily absorb the liquid in blood excessively, resulting in edema. However, leg swelling caused by heart disease develops relatively slowly, and many elderly people only notice the abnormality because their feet are swollen and they can’t wear shoes. Cardiogenic edema of lower limbs does not need deliberate treatment, and the heart function is restored, and the symptoms of edema can naturally be significantly improved.

  Mosquito bites can also cause edema of lower limbs.

  Recently, Mr. Wang was bitten by a bug when he went out for an outing. After scratching his calf wound, he developed redness and edema. He was diagnosed with erysipelas after seeing a doctor.

  Erysipelas is an infection involving superficial lymphatic vessels of dermis, and the main pathogenic bacteria are group A β Streptococcus hemolyticus Any inflammation of the skin, especially the inflammation with chapped or ulcerated skin, can be a way for pathogenic bacteria to invade the human body. Mild abrasions or scratches, injuries outside the head, unclean umbilical cord ligation and chronic leg ulcers may all lead to this disease.

  Infected with erysipelas, why does the lymphatic system have edema?

  Lymphatic system is a resource recovery and antivirus system of human body, which is widely distributed in human body. Lymphogenic edema mainly refers to the proliferation of subcutaneous fibrous connective tissue after repeated infection of soft tissue fluid on the body surface caused by the obstruction of lymph reflux in some parts of the body. If limbs are involved, it will be thickened, and the skin will be thickened, rough and tough like elephant skin in the later stage, also known as "elephant skin swelling".

  Lymphatic dysplasia or infection can cause swelling of tissues in the corresponding area. There are also some people who have slight abnormalities in the development of blood vessels in their lower limbs and are more prone to edema symptoms. We usually analyze the condition of patients’ lymphatic system by puncturing subcutaneous edema tissue fluid. The protein content of lymphedema fluid is usually very high, ranging from 1.0 to 5.5g/dl, while the protein content of edema tissue fluid with simple venous stasis, heart failure or hypoproteinemia is 0.1 to 0.9g/dl. However, this method can’t understand the lesion site and function of lymphatic vessels, and it is necessary to determine the development or obstruction of lymphatic vessels by lymphangiography.

  Thromboedema of cardiac vein in patients with low back pain

  Mr. Liu is obese, has irregular meals and stays up late for a long time. He is a lover of carbonated drinks and has a history of lumbar muscle strain and lumbar disc herniation. In recent days, he suffered from swelling and pain in his unilateral calf, which was obvious after sitting and standing, but did not relieve obviously after lying in bed. After examination by a doctor, deep venous thrombosis has formed in his lower limbs.

  Seeing the doctor’s diagnosis, Mr. Liu was puzzled and felt that the thrombus came suddenly. Actually, it is not. He is obese, does little exercise, stays up late, and has an unreasonable diet. These factors will easily lead to an increase in blood viscosity. In addition, he suffers from waist disease, and will stay in bed and take medicine when the pain attacks. Staying in bed for a long time will make the blood flow slow, the muscles will not pump enough blood, and it is easy to form a thrombus. At the same time, although taking medicine relieved waist inflammation, it also concealed other symptoms, thus delaying the opportunity to see a doctor. Therefore, we remind patients with lumbar diseases to pay attention to the phenomenon of edema in limbs.

  Venous thromboedema is common after surgery, trauma, long-term bed rest and long-term desk workers. The vast majority of venous thrombosis of lower limbs is painful first and then swollen, and the more swollen it is, the more painful it is. The most common harm of this disease to human body is pulmonary embolism caused by blood clots falling off, which leads to death. Some blood clots may also cause cerebral thrombosis, renal thrombosis and intestinal thrombosis. The degree of harm mainly depends on the proportion of blood vessel blockage and the shape of thrombus. After regular anticoagulation and anti-inflammatory treatment, a considerable number of patients’ conditions can be stable, and regular medication can be taken later. For those with serious blood vessel blockage and the risk of thrombus falling off, timely surgery is needed. At present, the implantation of inferior vena cava filter is the main method to prevent fatal pulmonary embolism caused by thrombus shedding in acute stage, and it is a minimally invasive operation by interventional method. If thrombus is ablated after anticoagulant therapy, surgery can be avoided; If the patient has persistent high fever, sepsis, uncontrollable infection and irreversible necrosis of lower limbs, it may be necessary to consider amputation.

  Generally speaking, there are many reasons for edema of lower limbs, which cannot be enumerated here. For healthy people, we suggest that you do the following three things in your daily life to avoid edema as much as possible. First, exercise moderately, avoid sitting and lying for a long time, and pay attention to moving the lower limbs when flying for a long time; The second is to supplement water properly and eat fruits and vegetables reasonably to avoid blood viscosity; Third, those who suffer from physical injuries due to diseases or various reasons, and need to use anti-inflammatory and anticoagulant drugs for prevention under the guidance of professional doctors, should follow the doctor’s advice and take drugs correctly.

Ford Mondeo price cut to 129,800, is it cost-effective?

In fact, during the period of the rapid rise of new energy vehicles, it was still very difficult for the fuel vehicles developed by second-tier brands to break through in the market. After all, the popularity of the models developed by first-tier joint venture fuel vehicle companies was decreasing, and many models developed by second-tier brands were naturally neglected. For example, the overall product quality of Hyundai’s products has been significantly improved after the replacement, but this car is still unpopular in the market. However, the Ford we are talking about today has achieved a turnaround in the market.

The Ford Mondeo car was on the market at that time. It was also very sluggish sales. It was not until the replacement was completed in the past two years that the whole vehicle returned to the public eye. In order to impress consumers, the threshold for new cars is constantly lowered. The most crucial point is that after the current 2025 version of the model is listed, the price is also 129,800. The cost performance of the whole vehicle is very good in the fuel B-class car. Today, let’s take a look at this American intermediate car. Is it in line with your vision?

From the perspective of sales in recent months, Ford Mondeo’s sales performance is still very good, basically maintaining a monthly sales volume of about 5,000 units. This performance is already very successful for the current situation of Ford. After all, many first-line mid-range cars have also sold thousands of units. It can be said that Mondeo’s price reduction in the past two years has indeed revitalized this model very well.

First of all, from the perspective of the overall appearance design, the new car features a highly recognizable dynamic mouth grid grille, with a very sharp headlight shape and a split design. At the same time, from the side design of the body, the new car features a 5-door hatchback design, a 20-inch low-resistance large wheel hub, and a segmented rear wing, all of which create a sporty temperament of the vehicle. It can be said that the car’s appearance is still in place.

At the same time, in terms of space, the new Mondeo standard version has a body length, width and height of 4935x1875x1500mm, the sports version has a body length, width and height of 4920x1920x1600mm, and the body wheelbase is 2945mm. The space setting of the American car is also quite good. Even if a person who is 1.78 meters tall sits in the back row, he can easily tilt his legs.

The interior of the new car still pays more attention to the improvement of texture. The soft and genuine leather materials used inside the whole car are more delicate to the touch. The central control of the colleague is equipped withThe large 1.1-meter-long screen composed of a 12.3-inch LCD instrument and a 27-inch central control screen, equipped with the SYNC + 2.0 system, also enhances the technological atmosphere of this car.


Finally, there is the power system of this car. The fuel version of Changan Ford Mondeo provides a 1.5T/2.0T gasoline engine, of which the new Ford Mondeo is equipped with a 1.5T gasoline engine with a maximum output power of 140kW and a peak torque of 258N · m, while the 2.0T gasoline engine has a maximum output power of 187kW and a peak torque of 393N · m. Of course, the new car also has a hybrid system for consumers to choose from.

At the beginning of the new car’s launch, I went to test drive the 1.5T version, because the mainstream models themselves are all 2.0T versions, and the overall driving is still relatively easy. Many people are concerned about whether the 1.5T version is enough? From the dynamic experience point of view,The power is actually sufficient, especially in urban areas, there will be no shortage of power. At high speeds, when you want to accelerate from 100kph to 120kph, you need to step deeper on the accelerator, and the chassis of the vehicle is relatively complete. The overall driving texture is acceptable to the driver.

Now on the market, the price of mainstream fuel intermediate cars are falling, this Ford Mondeo is currently 129,800 price, is indeed sincere, for many consumers who want to start intermediate fuel vehicles and not too much budget, this car is more worthy of consideration at the moment.

2024 Jaguar XFL launch: starting price 399,900 yuan

  In detail, the front face of the new car features a new matrix diamond-shaped theme design front grille, and is equipped with the iconic double J-Blade LED headlights.

  From the side, the new car still adopts a very simple design style, with simple and elegant lines and a very slender appearance.

  In terms of interior, it comes standard with a 12.3-inch full-LCD virtual instrument cluster and an 11.4-inch suspended curved screen, providing luxury Windsor leather seats, front row with 3D embossed Jaguar pattern, support for 16-way electric adjustment, with heating ventilation, memory, and massage functions.

  As a medium and large luxury car, the rear of the new car also provides a central armrest, flying wing headrest and soft pillow, and the rear seats also support heating, ventilation, massage, and waist adjustment functions.

  In the power section, the 2024 Jaguar XFL continues to be powered by the Avionics 2.0-liter turbocharged engine, providing three power options.

  In addition, the new car comes standard with Jaguar Drive Control, which offers four driving modes and can adjust the steering wheel and throttle sensitivity according to road conditions.

Lighting | deep learning empowers spectral imaging

Writing | Huang Longqian

Recently, from the School of Optoelectronics, Zhejiang University Hao Xiang The team of researchers is "Spectral Imaging with Deep Learning"The topic is Lighting: Science & Applications Published a review paper, sorted out the spectral imaging technology based on deep learning, explained the principle and research summary of its various technical routes, and organized the current spectral imaging dataset, outlining the possible future trends and challenges.

First, spectral images

The image we usually see in the display screen is an RGB three-color image, which has three channels of red, green and blue, that is, the color of each pixel is formed by superimposing the three colors of red, green and blue. If the three-color image is expanded to ten colors, hundred colors, and thousand colors, then our control and rendering of the image color will be extremely fine. An image with so many bands is a spectral image (term explanation >): it has more than three bands, which can be thirty or even hundreds.

Figure 1 Schematic diagram of a spectral image composed of 9 bands

The spectral information of a substance can fully reflect its internal physical structure and chemical composition. When there are enough wavelength bands in the image, each part is a spectral curve – reflecting the structural composition of the place. Therefore, the spectral image not only reflects the spatial characteristics of the imaging target, but also contains its structure and composition characteristics. Therefore, in addition to fine image rendering, the key application of spectral images is material composition analysis, which is widely used in remote sensing, medical detection, food detection and other fields.

Second, spectral imaging

Spectral imaging is a combination of imaging technology and spectral detection technology, and the main technical goal is to obtain spectral images. Traditional spectral imaging technology is scanning(Including point scanning, line scanning, band scanning)By constantly moving the spectrometer to obtain the spectrum of each point, a two-dimensional image is finally obtained. This scanning spectral imaging system is bulky and slow, which has been criticized.

Figure 2 Scanning spectral imaging (from left to right, point scan, first scan, and band scan)

With the development of computational optics, computational spectral imaging has become a new spectral imaging method. The method uses some coding to make the hidden spectral information enter the detector in a certain way, and finally uses the optimization algorithm to reconstruct the spectral image. The traditional computational spectral imaging method is iterative. Although it has effectively reduced the size of the system compared with the scanning spectral imaging, it has a great computational burden, often requires several minutes or even hours of iteration, and the reconstruction accuracy is relatively average.

The huge burden of data computing prompts people to think and look for more effective spectral reconstruction algorithms. In recent years, deep learning has developed rapidly, and the powerful pattern recognition and feature extraction capabilities of deep neural networks after good training have been favored by spectral imaging researchers. Deep learning methods have become the object of exploration, and deep learning has gradually empowered spectral imaging.

Methods of deep learning

The process of computational spectral imaging coding sampling system design and spectral image reconstruction, deep learning technology can be applied in every aspect of the process. How to effectively classify these different techniques is a key issue. The review proposes to classify according to the properties of light, that is, the computational spectral imaging system is divided into amplitude coding, phase coding and wavelength coding according to different coding methods.

(1) Amplitude-encoded spectral imaging

Figure 3: The spectral coding process in a coding aperture system

Amplitude-coded spectral imaging is achieved through a coded aperture system(CASSI)Conducted, using coding aperture(Amplitude mask)Amplitude coded spectral imaging based on deep learning replaces the iterative algorithm of compressed sensing recovery with deep neural networks, and performs efficient spectral reconstruction through codec co-optimization, iterative expansion neural networks, and untrained networks.

(2) Phase-encoded spectral imaging

Figure 4: A phase-encoded spectral imaging system

Phase-encoded spectral imaging through diffractive optics(Diffraction Optical Elements, DOE)Phase coding is achieved by designing the two-dimensional height profile of the DOE to achieve specific phase delays at different positions. Phase coding affects different spectral components through Fresnel diffraction, and then by modeling the diffraction process, the original spectral image can be reconstructed by the algorithm. Due to the complexity of diffraction calculation after phase coding, traditional iterative algorithms are difficult to achieve effective recovery of spectral images. This problem has been solved after the emergence of deep learning. At present, the spectral recovery of phase coding is mainly carried out through deep neural networks. Compared with amplitude coding, phase-encoded spectral imaging has the advantages of small light energy loss and compact system.

(3) Wavelength-encoded spectral imaging

Wavelength-encoded spectral imaging directly encodes the image in the spectral dimension and can be performed through optical filters. RGB images can be regarded as a kind of spectral coding. At present, the mainstream wavelength coding methods use existing RGB or design optical filters, and the encoded spectral reconstruction mostly relies on deep learning technology.

Direct spectral reconstruction based on RGB images is a very hot direction. With the NTIRE 2018 and NTIRE 2020 spectral reconstruction competitions, many deep learning technology teams participated, greatly expanding the existing deep learning spectral restoration techniques. The researchers analyzed the RGB spectral reconstruction and filter design spectral reconstruction involved in deep learning, and divided the reconstruction methods into point reconstruction and block reconstruction, so as to introduce each reconstruction method.

Figure 5 Codec Cooperative Design Spectral Imaging Technology [

[2] (Source: Advanced Theory and Simulations)

Wavelength coding based on custom optical filters is an emerging spectral imaging technology in recent years. By designing wide-spectrum filters, greater coding freedom can be obtained than RGB filters. Combined with effective deep learning technology, compact, fast and accurate spectral recovery can be achieved.

IV. Future Outlook

Based on current deep learning techniques and spectral imaging techniques, the researchers have made some suggestions for the future development of deep learning-based spectral imaging. These include the large-scale and normalization of datasets, and the use of large neural networks(For example Transformers)Introduce additional information such as object categories, solve the problem of layer disappearance in the process of codec collaborative design, and use neural networks architecture search technology.

Fan Weiqi warms up for the concert, and the big S supports the sisters to hug (Photo)

   



Fan Weiqi


  


  



Fan Weiqi and Big S  



  Fan Fan and Friends


  Fan Weiqi, who has been out for seven years and is about to hold her first large-scale ticketed concert in August this year, held a warm small singing activity at the famous PUB "Riverside Message" in Taipei last week to warm up in advance. Fan Fan’s super charm not only made 160 pre-purchase tickets sold out, but also fans who bought tickets on the spot queued up. Nearly 300 fans crowded "Riverside Message". Not only did parents come with their 8-year-old son and the whole family, but also a 70-year-old super fan grandma came to support Fan Fan, who was both happy and moved. After Fan Fan sang 10 classic songs such as "Thinking Too Much" in one go, the live encore was continuous, and fans asked for encore four times! Fan Fan humorously said, "ENCORE? Okay, then UNCLE is here!"


  The night before, the little junior sister Guo Jing started singing three songs, which immediately heated up the atmosphere of the scene. In addition to singing her favorite classic songs, Fan Fan also interpreted the English song "Bubbly" (original Colbie Caillat) for the first time, as well as the Taiwanese song "Home Queen". Fan Fan revealed that since her debut seven years ago, this is the first time she has sung Taiwanese songs publicly on the stage, in order to pay tribute to Jiang Hui, the senior singer in the music industry, and hopes that her ticket-selling concert this summer can sell as well as the second sister Jiang Hui’s four-game Little Arena concert! Fan Fan, who was originally worried that the pronunciation of the words was not good enough, may have been a little nervous when singing "Home Queen", or accidentally sang the wrong paragraph of the lyrics, and also pronounced "Junior" as "Xiulian", but the fans were still fascinated and responded enthusiastically, and they didn’t mind at all.


  In addition to a large number of die-hard fans present to support, this night’s "Riverbank Message" was also star-studded. Friends in the circle, black Chen Jianzhou, big S Xu Xiyuan, Wang Hongen, Liu Rongjia, as well as Taiwan beer players He Shouzheng and Chen Shinian, were all present to support! When Fan Fan Anke sang "Black and White", he emotionally expressed that the song would be dedicated to "Mr. Black" who was also present, which caused a burst of cheers and screams from the fans on the scene, and black Chen Jianzhou always held a DV to record all Fan Fan’s performances on the stage. And the last song "Can’t You Be Brave", Fan Fan would like to dedicate it to the good sister who filmed this MV together, Big S!


  Fan Fan revealed that "Da Wang" (referring to the beauty king Da S) has not appeared in the nightclub for a long time. 10 minutes before the performance, she heard her good sister Da S express that she would come to the scene to listen to the song. She was also worried that the crowd at the scene was too crowded and the air was not good. She asked Da S not to come, but she insisted on coming, which really touched her. When the audience of fans continued to arch Da S on the stage to sing, Fan Fan also saved the good sisters. Fan Fan said that this song is also given to all the fans, "Many times, we can not be brave, but after tomorrow, we must continue to live a brave life!"


  After the last encore song "Can’t Be Brave" was sung, the "uncle" who was full of people still appeared, but it was almost twelve o’clock in the morning. Fan Fan said to the fans in the audience: "If you want to listen to more exciting content, the ticket sales concert is coming again, and everyone has to be responsible for buying ten tickets!" After the performance ended successfully, many fans were still reluctant to leave. Fan Fan finally responded to the request and took photos and signed autographs with everyone, and the atmosphere was warm.

Is Tesla FSD "Catfish" about to enter China? Set a high-level intelligence to drive PPA head-on

Tesla FSD will enter China, can domestic car companies still fight? According to media reports, "Chen Kele, deputy director of the Intelligent Manufacturing Promotion Department of Shanghai Economic and Information Committee, said that in the next stage, Shanghai will further deepen its cooperation with Tesla, promote the layout of functional sectors such as autonomous driving and robots in Shanghai, and jointly build a technology industry cluster with core technological advantages and facing the global market."

This news has also been interpreted by the outside world as a signal that Tesla FSD is about to enter the China market. If so, then an overseas "catfish" is finally coming.

Tesla has been deeply involved in the field of autonomous driving for a long time, but can the late FSD still penetrate the smart car market in China? After all, during the absence of Tesla FSD, intelligent driving, including Tucki NGP, Huawei NCA, and even Jidu PPA, a company known as "automobile robot", has been accelerated, and China’s wisdom has changed.

The competition is raging, and the domestic intellectual drive is "anti-"roll"Tesla

Tesla is not only the leader of new energy vehicles, but also the promoter of autonomous driving. Since the release of Autopilot in 2014, Tesla’s assisted driving system has become a pioneer in assisted driving worldwide with its leading landing, rich functions and continuous OTA upgrade. When it comes to smart driving, Tesla is second to none.

However, times have changed. Standing in the smart car market in 2023, in the face of the fully blossoming domestic intelligent driving system, Tesla not only no longer occupies an overwhelming advantage, but even has the impression of being overtaken.

At present, almost all domestic smart cars already have very mature intelligent driving functions in high-speed and parking scenes, and are making efforts to assist driving in urban scenes.

For example, when Tucki launched Xmart OS 4.2 in March, it simultaneously released the first-stage capabilities of XNGP, and many of its models can open point-to-point city NGP (Intelligent Navigation Assisted Driving) in Shanghai’s high-precision map coverage area. In April, Huawei released the HUAWEI ADS 2.0 system. In the third quarter of this year, the urban NCA will realize the landing of 15 cities without maps, and in the fourth quarter, 30 cities without maps will be added.

When the limited edition of ROBO-01 lunar exploration was released in October last year, Jidu released the point-to-point navigation assistance PPA simultaneously. According to the official introduction, Jidu PPA has the high-level intelligent driving ability of "multi-domain integration" in high-speed domain, urban domain and parking domain. When ROBO-01 is delivered, the available scene coverage of PPA will reach the leading position in China. The proportion of cities in the scene of users using cars is much higher than that of high-speed and parking, so the "multi-domain integration" of PPA is the only way for high-level intelligent driving.

In addition, car companies such as Ideality, Weilai and even the Great Wall (mainly relying on its subsidiary) have similar promotion plans for urban intelligent driving.

It can be seen that Tesla, which once dominated, is full of uncertainty in the face of the competition in China’s smart driving market in 2023.

The competitive advantage of domestic intelligent driving is not only reflected in the localization of better understanding of China road conditions, but also in the leading hardware configuration. Take Tucki Expressway NGP as an example. By the end of August 2022, its accumulated mileage has reached 36.9 million kilometers. The concentration is backed by the technical empowerment of Baidu Apollo, which is not only the L4-level automatic driving ability, but also accumulated more than 50 million kilometers of test mileage. Complex "China characteristics" such as ghost probe, jam, and take-away riders all form a strong data advantage, which makes domestic intelligent drivers better understand the driving habits of China car owners and better adapt to the complex road conditions in China.

The hardware foundation determines the function of the upper software, and the domestic intelligent driver has been "armed to the teeth", and there are many volumes to be rolled. Among the representative brands of domestic smart driving, 500+TOPS computing power, 30+ sensors and laser radar are all embarrassed to take out their hands without being paired. For example, Aouita 11 is equipped with three lidar, Weilai ET7 and four Orin to pull the computing power to 1016TOPS. In addition to dual Orin X+ dual lidar, Qualcomm 8295 chip is the first to be equipped with the image convergence.

In addition to the efforts in configuration and function, the domestic intelligent driver has made multiple redundancies in safety. For example, two sets of automatic driving system perception schemes of "vision+laser radar" are applied in Jiji, which can work independently and be a safe backup for each other. In addition, the convergence has also achieved "cabin-driving integration". When the intelligent cabin domain control is extremely ineffective, the intelligent cabin domain control can take over the driving task, realize safe parking, and fully ensure the safety of intelligent driving. In addition to technology, it is the efforts made by China’s high-priced smart driving products in the popularization of science and technology.

Domestic intellectual driving technology equality,It is by no means a toy for a few people.

It must be said that Tesla’s software payment model has not only changed the business model of the traditional automobile industry, but has also been imitated by major manufacturers. However, Tesla FSD’s subscription price of 64,000 yuan is really not cheap.

The high price has discouraged many users. According to previous data, the opening rate of Tesla FSD in China is 1%-2%, and the opening rate in the global market is only about 11%, and it continues to decline. Moreover, at present, the domestic FSD is not a "complete body", which can be said to be a "castrated version" function.

Musk is also aware of this problem. In May this year, he released the news on his Twitter. Tesla will plan to provide all car owners in North America with a free one-month FSD fully automatic driving experience package, provided that the FSD is highly smooth and safe.

In fact, smart cars in China have also formed a relatively mature software payment ecology, and various optional packages for cockpit, software services and smart driving are extremely rich. At the same time, local smart car companies are also exploring new ways of playing, bringing leading functions to more users with the concept of universal technology.

Just like the limited edition of Jidu ROBO-1 lunar exploration, the official gave away many user rights and interests including high-level intelligent driving, charging and recharging, vehicle warranty, three-electricity warranty and so on for the users of lunar exploration, and they enjoyed it for life. Among them, the value of high-level intelligent driving is not less than 60,000 yuan, and it has achieved the first "following people but not following cars" mode in the industry, and you can continue to enjoy this right even if you change cars.

Xia Yiping, CEO of Jidu, even publicly stated that intelligence is standard in all departments, from the entry version to the high version, including laser radar and 35.6-inch integrated bottle. This move is tantamount to directly opening a new stage of high-level intellectual driving for science and technology inclusiveness in the domestic market.

In April this year, Ideality quickly followed suit, announcing that NOA software and services in the ideal AD Max 3.0 city will be free for life, and every AD Max user will upgrade the NOA in the AD Max 3.0 city and NOA at high speed for free.

The technology popularization of domestic smart cars is not the "backstab" of Tesla model, because technology should be popularized on a large scale instead of being lofty. With the hardware configuration and intelligent scheme of the centralized ROBO-01, there is no complicated "high-low matching" distinction. This uncomplicated and unconventional mode is not only completely different from other new domestic forces, but also a localized continuation of Tesla’s minimalist technology temperament.

Leading intelligent driving technology brings excellent driving experience to more car owners, which is the greatest significance of scientific and technological progress. At the juncture when FSD is about to enter China, a competition between local high-level intelligent driving and "overseas catfish" is also brewing.
