Can Huawei’s visual intelligence drive surpass Tesla? Pure vision confronts the dispute between cost and performance

Huawei HarmonyOS Ecological Spring Communication Conference was successfully held on the afternoon of April 11th. This conference focused on the new products of Zhijie S7 and MateBook. Zhijie S7, the first car built by Huawei and Chery based on HarmonyOS Zhixing model, was unveiled in November last year.

The intellectual community "returned to the furnace" after half a year, which attracted attention. Huawei chose to re-release it because of its Huawei visual intelligent driving system, which is the first time Huawei has launched a visual driving solution without lidar.

At the press conference, Yu Chengdong said that Huawei’s visual smart driver equipped with Zhijie S7 has surpassed Tesla, which is known as the "originator of vision", in real vehicle performance, showing strong confidence in its own scheme.

How does Huawei’s visual intelligence drive compete with Tesla’s visual intelligence drive on the premise of abandoning lidar? What kind of sensor does its technical strength come from? Huawei revealed the answer at the meeting.

Huawei officially released the first visual intelligent driving product-Huawei ADS Basic Edition. According to Yu Chengdong, the scheme can realize NCA intelligent driving navigation assistance on national expressways and urban expressways, including intelligent driving on and off ramps, coping with complex scenes such as road construction and cone-bucket diversion, and has certain ability to change lanes and avoid obstacles independently.

HUAWEI ADS basic edition is not equipped with laser radar, but realizes environmental perception through three millimeter-wave radars, 10 visual perception high-definition cameras and 12 ultrasonic radars, so as to build a visual intelligent driving scheme without laser radar.

At the press conference, Huawei ADS Basic Edition pointed directly at Tesla EAP(Enhanced Auto Pilot Enhanced Driver Assistance). Huawei claims that the comparative test results show that the coverage rate of Huawei’s visual intelligent driving is as high as 99.5%, the pass rate of ramp is 96%, and there is no degradation in the whole process. At the same time, it has the functions of intelligent speed regulation and identification of water horse cones. In contrast, the coverage rate of Tesla equipped with EAP is only 79%, the on-ramp pass rate is 68.75%, and it has been degraded 14 times, and it is impossible to identify obstacles of the opposite sex.

In terms of intelligent parking, Huawei’s visual intelligent driving has completely surpassed Tesla, which lacks support for different shapes, oblique rows and custom parking spaces.

As an optional function, Tesla EAP includes four functions: automatic lane change assistance, automatic navigation and driving assistance, intelligent calling and automatic parking, which need to be purchased at an extra cost. Tesla’s self-driving products are divided into three grades: BAP, EAP and FSD, of which BAP is the basic version and EAP is the enhanced assisted driving, and the two are free and charge $6,000 respectively. FSD is Tesla’s highest-level self-driving product, which has the functions of navigation-assisted driving, automatic lane change, automatic parking, intelligent calling, traffic signal recognition, and automatic turning of urban roads.

Zhijie S7 has launched five models, with the price range of 249,800 yuan to 349,800 yuan. Among the new models, the Ultra version uses a 100kWh battery pack, while the Max and Max+ versions have a price reduction of 20,000 yuan compared with the initial listing.

It is worth noting that Huawei Vision Smart Drive HUAWEI ADS Basic Edition is only installed in Zhijie S7 Pro rear drive long battery life version. In contrast, the version of Zhijie S7 Max with a price higher than 20,000 yuan is equipped with the same 192-line laser radar as that of Wenjie M9, with the longest detection distance of 250m, which is 20% higher than the industry average. Except for lidar, there is no difference in other configurations between the two models.

From this point of view, whether equipped with lidar has become the main difference between the basic version and the high-end version of Huawei’s ADS intelligent driving scheme, and the price difference between them is mainly reflected in this 192-line lidar.

What is the difference between Huawei Smart Drive with and without lidar? The former has enhanced its omni-directional anti-collision ability. After Zhijie S7 is equipped with laser radar, the effective range of forward active safety AEB is expanded to 4-150km/h, and the maximum braking speed is increased to 120 km/h; The effective range of lateral active safety is increased to 40-130km/h, and obstacles such as water horses can be actively identified.

The existence of lidar significantly improves the safety protection performance of vehicles, especially when dealing with emergencies such as "ghost probe". Previously, an owner of the M7 car in the border area encountered a "ghost probe" accident while driving at a speed of nearly 130km/h at high speed, and a pedestrian suddenly crossed the isolation belt and broke into the fast lane. Fortunately, Huawei’s intelligent driving system equipped with the M7 in Wenjie timely identified and took evasive measures to avoid the tragedy. This successful obstacle avoidance case is largely due to the lidar carried by the vehicle. Under extreme conditions, it is difficult to achieve such accurate perception only by visual sensors or human eyes.

In addition, the advanced version of HUAWEI ADS equipped with lidar has achieved wide coverage of roads in China, covering more than 40,000 towns and villages in China, including main roads, branch roads and even smaller roads. The third-party test data shows that the road coverage rate of the system has reached 99.56%. In contrast, the basic version of HUAWEI ADS-visual intelligent driving scheme is currently only applicable to NCA intelligent driving navigation assistance for national expressways and urban expressways.

Despite this, lidar is still recognized as the strongest sensor to achieve high-order assisted driving at this stage, even Huawei is no exception.

Why do some manufacturers choose to give up lidar? High cost is the main reason. Compared with the Zhijie S7Pro rear-drive long-life intelligent driving version, the Zhijie S7Max rear-drive long-life intelligent driving version is 20,000 yuan more expensive, mainly because of the addition of laser radar. Are consumers willing to pay for this?

In December, 2023, DJI Vehicle cooperated with Chery to launch the mass-produced model iCAR 03. This model adopts 7V pure vision sensor scheme, and the whole vehicle has no millimeter-wave radar or ultrasonic radar, making it the first automobile in China to realize high-order driving assistance function only by pure vision sensing hardware. With the help of pure visual sensor hardware, iCAR 03 also supports high-order assisted driving functions such as cross-layer memory parking, urban memory navigation and high-speed navigation.

The intelligent driving solution "Chengxing" launched by DJI Vehicle takes the inertial navigation stereo binocular sensor as the core sensing device, provides 7V and 9V pure vision sensor configurations, and supports extended multi-sensor such as lidar. This scheme can realize a variety of L2+ high-order intelligent driving functions with a computing power configuration as low as 32TOPS. Among them, the 7V sensor scheme includes an inertial navigation binocular vision sensor and five cameras, and the 9V sensor scheme adds two side-looking monocular cameras on this basis.

The hardware cost of DJI vehicle-mounted binocular vision intelligent driving scheme is extremely low. According to Shen Shaoshua, the person in charge of the vehicle in DJI, the hardware cost of the "Chengxing" platform can be reduced to less than 10,000 yuan, even reaching the level of 5,000 yuan, which is roughly equivalent to the price of a long-range lidar.

Both Chery’s cooperation with DJI Vehicle and Huawei’s cooperation have put forward a vision intelligent driving scheme without lidar version, which shows the active exploration and trade-off of domestic automobile manufacturers in the field of intelligent driving, and reveals how to introduce intelligent driving technology into a lower price range through trade-offs.

Although lidar is irreplaceable for its high-precision sensing ability, even Huawei acknowledges its watershed position between the basic version and the high-end version of HUAWEI ADS. However, with the intensification of competition in the automobile market, domestic automobile manufacturers are eager to introduce intelligent driving technology into a lower price range, and enterprises such as DJI and Huawei have achieved mass production of visual intelligent driving solutions that do not rely on lidar.

Therefore, reducing the cost of lidar has become a top priority.

Only by accepting and acknowledging others’ differences can our differences be accepted. This is a process of growth.

　　 (Comprehensive China Network, People’s Network, China Youth Daily)

　　Cctv news(Reporter Wang Xiaoying) Nanyin, also known as "Xianguan", is one of the oldest existing kinds of music in China. It came from the Central Plains to southern Fujian, and has preserved the traditional and ancient folk singing methods before the Tang Dynasty, singing classics in Minnan, and is called the "living fossil" of music culture.

　　Founded in 1954, Xiamen South Orchestra is one of the only two professional performing groups of Nanyin in China. In recent years, Nanyin has made great efforts to innovate and cultivate talents, and a group of post-90 s and even post-95 s students have participated, which has given Nanyin a new "voice" machine.

Nanyin oratorio "Jin Shi Yin"

　　Compilation of reference books and promotion of Nanyin’s first computer-generated scale edition published at the end of the year.

The score of Nanyin Gongchi Score, which was independently developed by the South Orchestra, was played by computer scoring software.

　　Xiamen South Orchestra is located in the west gate of Sun Yat-sen Park, a historic building with southern Fujian classical garden style — — — In "Nanyin Pavilion", its predecessor was Xiamen Jinfengnan Orchestra.

　　Mr. Ji Jingmu, the first head of the Southern Orchestra, was highly accomplished and was praised as a "great master" and a "master of southern music" by the southern music circles at home and abroad. During his lifetime, he compiled more than 500 pieces of traditional southern music and created many new pieces, among which the instrumental music "Fishing Songs in the Bohai Sea" jointly created by colleagues in the music industry was praised as the fourteenth set of southern music.

　　Thanks to the guidance of Ji Jingmu, Bai Hou, Ren Qingshui, Bai Lihua, Lin Yuyan and other famous teachers, Nanle Troupe not only abides by the previous law, but also dares to innovate, forming a unique artistic style. In terms of instrumental performance, Xiamen South Orchestra pays attention to the tacit cooperation between musicians, especially the skill of playing the flute string in the cave, which is highly respected in the southern music circle; In singing, it pays attention to "emphasizing rhyme over lightness" and "clear pronunciation and mellow voice", which has been praised by southern music circles at home and abroad for decades.

　　In recent years, the Southern Orchestra has adhered to the road of attaching equal importance to inheritance and innovation. On the one hand, it has continuously excavated and sorted out traditional tracks, on the other hand, it has actively created Nanyin masterpieces and actively participated in various national art competitions, winning awards frequently.

　　In 2010, Nanyin’s Gathering in Baodao won the program award of "Peony Award, the highest award of China Quyi", becoming the only play in Fujian Province and one of the five in China that won this honor.

　　Yang Xueli, head of Xiamen Nanyin Orchestra, introduced that since 2015, Nanyin Orchestra has started the data rescue and protection plan, and edited and published the Selected Works of Nanyin Ancient Music by using the self-developed Nanyin Gongchi notation computer scoring software. This selection is the first in Xiamen Nanyin community and the first Nanyin score in Xiamen, which has become an indispensable reference book for Nanyin lovers, providing a more detailed Nanyin reference book for Nanyin practitioners and enthusiasts, and standardizing the singing scores of Xiamen schools. At present, they are editing and proofreading Xiamen’s first computer-generated version of the Complete Works of Nanyin Finger Spectrum, which is expected to be published by the end of this year.

　　After 90, students joined the new "sound" machine that glowed with Nanyin.

Xu Dani on the stage

　　Born in 1996, Xu Dani was influenced by her aunt who sang Nanyin. She entered Xiamen Art School at the age of 15 in 2011 and began to try to learn Nanyin.

　　"Although Nanyin is sung in Minnan, she can speak Minnan and may not be able to sing Nanyin." Xu Dani said that it was difficult to learn at first, and the pronunciation and articulation were very demanding, especially it was difficult to adapt to the slow rhythm of Nanyin.

　　Yang Xueli introduced that Nanyin really pays attention to articulation, and its tunes are euphemistic, simple and elegant.

　　Many gestures and movements of Nanyin are delicate and exquisite. The longer the contact, the more beautiful it feels, and the slow performance rhythm of Nanyin as a whole is easy to calm people down. After studying, Xu Dani fell in love with Nanyin. In 2014, she began to perform on stage.

　　In order to cultivate talents, Nanle Orchestra and Xiamen Art School jointly run a school, and sent old masters and top teachers to participate in Nanyin professional teaching. There were 17 students studying with Xu Dani, and these post-90 s students also injected new vitality into Nanle Orchestra.

　　"In the past, the performance form of Nanyin was relatively simple, such as four stations and one singing." Xu Dani said that their new students, on the basis of the original, asked the master to innovate. At present, many popular elements have been added to the repertoire, such as accompaniment chorus, percussion and other Chinese and Western instruments.

　　Although she excels in some tracks, Xu Dani still feels that compared with the old masters, she has only learned a little, especially the most difficult part of Nanyin’s singing.

　　Yang Xueli told reporters that the new batch of post-90s or even post-90s students is actually very surprising. They have excellent skills and stick to the tradition. Many of them have made their mark in national, provincial and municipal events and made great achievements.

　　Go out of "Nanyin Pavilion" and fly overseas.

Nanyin’s performance "Gathering in Treasure Island" won the program award of the sixth China Quyi "Peony Award".

　　In order to let more people know about Nanyin, the Southern Orchestra took the initiative to perform in the campus and community, and will perform free of charge at Nanyin Pavilion on Sunday for the public to watch.

　　Yang Xueli introduced that the Southern Orchestra regularly organizes Nanyin training classes and Nanyin summer camps jointly with Nanyin Society and primary and secondary schools in Xiamen, or sends outstanding Nanyin performers into schools and communities to give lectures, and holds a session of Xiamen Nanyin Singing Competition every year, which has been held for 19 times so far, cultivating a group of new people, creating and producing a number of new works, and reviving Nanyin.

　　Nanyin is widely spread in Hongkong, Macau and Southeast Asian countries where Minnan people live, especially in Taiwan Province. Because of this, Nanyin is endowed with a special historical mission and will play an irreplaceable role in promoting cross-strait artistic exchanges, enhancing cross-strait cultural identity and maintaining cross-strait emotional ties.

　　On behalf of Xiamen City, Xiamen South Orchestra went to Taiwan to participate in the "Fujian Cultural Treasure Island Campus Tour — — Nanyin enters the campus "activity, and enters 11 colleges and universities in Taiwan Province to promote performances.

　　In recent years, the Southern Orchestra has been invited to visit the Philippines, Singapore, Japan, France, New Zealand, the Czech Republic, Hong Kong, Macao and Taiwan and other countries and regions, actively carrying out foreign art exchange performances, and promoting China’s excellent traditional culture to the world through the international stage, so that people can further understand the value and charm of Nanyin, a world heritage.

Today, it is reported that Liu Yilin, senior director of Xpeng Motors Autopilot Products, will leave his post. At the same time, it is said that he will join NVIDIA and join Wu Xinzhou, former vice president of Tucki Autopilot.

In this regard, Liu Yilin himself wrote that any "joining other enterprises" at present is false information.

In August, 2023, Wu Xinzhou, the former vice president of autonomous driving in Tucki, left Tucki and joined NVIDIA as the "global vice president", reporting to Huang Renxun. According to media reports, after Wu Xinzhou left his post, the responsible persons of autonomous driving, including perception, decision-making and lidar, also left one after another.

It is understood that Wu Xinzhou is the core figure of Xpeng Motors’s autonomous driving business and once served as the vice president of Xpeng Motors’s intelligent driving business. He joined Xpeng Motors in March 2019 and was fully responsible for the autonomous driving business and team management. Wu Xinzhou graduated from Tsinghua University and received his master’s and doctor’s degrees in electronic engineering from the University of Illinois at Urbana-Champaign. Before joining Tucki, he was the head of the autonomous driving R&D team in Qualcomm.

According to Wu Xinzhou himself, he left his job because of family and various reasons, and he said that he would return to the United States. He Xiaopeng also mentioned that Wu Xinzhou expressed this intention in the second half of last year.

Wu Xinzhou’s departure is an important change for Xpeng Motors. During his stay in Xpeng Motors, he promoted the rapid development of the company’s autonomous driving technology, including self-developed intelligent driving software algorithms, and promoted Xpeng Motors to become a leading domestic autonomous driving technology enterprise. His departure may have a certain impact on Xpeng Motors’s autonomous driving business.

　

　　Zhongxin Jingwei Client May 1 ST (Zhang Yanzheng Intern Liu Yi) "Recently, I have always brushed Changsha food videos on Tik Tok, just ‘ May Day ’ During the small holiday, I plan to take my family to orange island to have a look, and try authentic Hunan cuisine by the way. As a result, I opened the booking platform and found that even the cheap hotel chain has risen from the original early 100 s to the price of six or seven hundred yuan, and the middle and high-end hotels have even started at 1,000 yuan, which is really unaffordable. " Ms. Li from Liaocheng City, Shandong Province told the client of Zhongxin Jingwei.

　　During the May Day holiday, many people chose to "punch in" in popular tourist cities. According to the data of Qunar. com, the number of domestic hotel reservations during the May 1 holiday in 2021 has exceeded 40% in the same period in 2019, a surge of 8.1 times compared with the same period in 2020. Hotel prices have been rising with the booking volume, with an average price of 458 yuan per night, which is higher than that of 85 yuan in the same period of 2019. The price has increased by 22.79%, and the price of some popular online celebrity city hotels has even increased by 112%. Are you still going to look for poetry and distance?

　　Online celebrity City Hotel "City Price Increase"

　　Recently, as a consumer, Zhongxin Jingwei client learned that the prices of hotels and homestays in some popular online celebrity cities, such as Changsha, Xi ‘an, Hangzhou and Chengdu, have skyrocketed, and it is hard to find a unique room.

　　The staff of Days Hotel Changsha Jiasheng said that the prices of almost all hotels have increased during the May 1 ST period, while in Changsha, hotels will adjust their prices every May 1 ST, 11 th and Spring Festival. “‘ May Day ’ Most of the rooms have been booked during the period, leaving only a few rooms. " The staff member said. The staff of Changsha Pinpin Hotel also said that most of the hotel rooms have been booked in March, and the price of Pinzhi twin room, which usually costs 619 yuan/night, is now 998 yuan/night.

　　The Zhongxin Jingwei client looked at the third-party booking platform and found that during the "May 1" period, many hotels and homestays in Changsha were full or only two or three rooms were left. Among them, Changsha Exotic Impression W Hotel has only one room with a 180-degree deluxe river view big bed room. Among the hotel’s characteristic rooms, the Xiangjiang River modern river view twin room with a price of 1320 yuan/night and the 270-degree full river view executive suite-the supreme package with a price of 1329 yuan/night have all been booked.

　　Room reservation of a hotel in Changsha and Xi ‘an Source: Ctrip

　　According to the "May Day" popular destinations published by Qunar.com, Changsha is the most "online celebrity" city in 2021 according to the current hotel reservations during the "May Day" holiday. Up to now, the hotel reservation in Changsha ranks second in China, with an average price of 385 yuan per night. The number of reservations increased by 1.5 times compared with the same period in 2019, and the growth rate led the new first-tier cities.

　　The report also shows that the prices of hotels in Changsha, a popular city in online celebrity, rose by 34%, Xi ‘an by 112%, Chengdu by 23%, Hangzhou by 20% and Zhuhai by 32%.

　　The staff of Xi ‘an Yunhe Night Park Hotel said that the price of the hotel room was relatively high during the May Day period, and the price of the elegant big bed room at night park was around 400-500 yuan at ordinary times, and now the price is 887 yuan/night. The Sino-Singapore Jingwei client inquired about the third-party booking platform and found that the hotel’s executive luxury parent-child room with a price of 3,212 yuan/night and the cloud and luxury twin room with a price of 2,908 yuan/night have all been booked. The staff of Hangzhou Weiyuan Hotel said that the only courtyard projection big bed room in the hotel is now priced at 1387 yuan/night, and the pre-holiday price of this room is around 700 yuan.

　　Netizen: The price is "outrageous"

　　"Some time ago, I unpacked the ticket blind box and got a ticket to Shanghai. I originally wanted to take advantage of ‘ May Day ’ Go to Disney on vacation, once ‘ Princess at large ’ However, the price of the hotel is really a bit discouraged. It is too close to live and it is a waste of time. " Ms. Zhang from Bayannaoer City, Inner Mongolia, told the client of Zhongxin Jingwei that she didn’t intend to travel too far, but just in time for the blind box activity of air tickets to be drawn to Shanghai, she temporarily decided on the travel itinerary. I didn’t expect hotels around Disney to be expensive and difficult to book. "It’s also my fault that I didn’t make plans early, so I have no choice but to consider shortening my itinerary and playing less for a few days."

　　Ms. Wu of Chongqing said to the client of Zhongxin Jingwei: "Express hotels are going to look like I can’t afford to live. It was originally a cheap and convenient plan to stay in the seven-day chain next to the scenic spot. When I searched the price, the big bed room would cost nearly 500 yuan a night."

　　On the social media platform, many netizens said that the price of hotels during this year’s "May 1" holiday rose significantly, and the price was "outrageous".

　　The south wind has not yet started-:Take Xiamen, where I live, for example, there are more than 200 hotels, and it will take 2,000 to get to May Day. It is understandable for hotels to raise prices appropriately during holidays. After all, business is not good at ordinary times, and holidays can make a wave, but this increase is too outrageous. Most of the money spent on accommodation when going out for a visit.

　　@ Shh, don’t say anything: it’s outrageous for more than one hundred to rise to seven or eight hundred, and it’s outrageous for small hotels to rise to two or three hundred.

　　@ Xiang kaixin: I have been planning the May Day trip for a long time, but it’s outrageous to be turned away by the hotel price of 3 times the scenic spot …

　　@ Learn good Xinyi sauce: During the "May Day" period, the price of this hotel is outrageous, and the usual room type of 180 is "May Day" 899.

　　According to Ctrip’s report data, during the May Day holiday in 2021, the order volume of Ctrip platform hotels increased by 43% compared with the same period in 2019. Many high-star hotels have been hard to find a room, and the price of hotel orders has risen, surpassing the average price in 2019. Judging from the hotel booking trend of the platform, during the "May 1" period, orders for 4 and 5 diamond high-star hotels accounted for over 50%, and more tourists were willing to buy high-quality travel services in high-star hotels.

　　Lan Xiang, dean of the Qunar Big Data Research Institute, believes that as early as this year’s Spring Festival, the "May 1" hotel reservations have increased significantly because a large number of suppressed travel needs have not been released. Lan Xiang said, "Although many tourists visited relatives and traveled during the just-concluded Qingming holiday, due to the length of the holiday, most of them will still choose ‘ May Day ’ Travel on holiday. "

　　Expert: it is not appropriate to interfere excessively with the price increase.

　　Zhang Yuhao, a lawyer of Beijing Weiheng Law Firm, said in an interview with Zhongxin Jingwei client that as the festival approaches, some homestay hotels balance the profit ratio of the whole year by appropriately raising prices, and such business practices may not constitute an illegal act of "driving up prices". "If the relevant operators join hands with neighboring operators in order to achieve violent profits within a certain period of time, and the price is greatly raised beyond a reasonable range; Or fabricate or disseminate false or related information, deliberately causing the price in this area to increase significantly beyond the reasonable range. If the above two situations occur, it may constitute ‘ Drive up prices ’ Illegal behavior. "

　　Zhou Mingxi, founder of Jingjian think tank, believes that the price increase of hotels or homestays is a market behavior that reflects the relationship between supply and demand. "In the period of oversupply, such as when the epidemic is serious, and in the traditional off-season of tourist cities, many five-star hotels sell for only three or four hundred yuan per night, which will definitely lose money from the perspective of operating costs. And the same room, in the peak season and holidays, the price of the room can reach several thousand yuan per night, the difference is multiplied. In the off-season, no one guarantees the income of the operators, and it is not appropriate to interfere excessively with the price increase in the peak season. "

　　"It should be noted that the market supervision department should focus on monitoring whether the hotel price is transparent, whether the room is hygienic and safe, whether it is suspected of exaggerating false propaganda, etc., to avoid the situation that the quality is not proportional to the price."

　　When you mention the name "",you may first think of a music platform with the same name, but now, the cool music car Haval Cool Dog, which also has an indissoluble bond with music, is born. Haval Cool Dog from Lemon Platform, as the second car of dog category, carries the strategic mission of brand layout to enter the compact urban off-road market. The biggest highlight of positioning the Haval cool dog house with cool music car can be summarized by a multiplication: 4×18. So what exactly do the two mysterious numbers in this multiplication represent? Let’s talk about it first.

　　Analysis of 4×18 Highlights of Haval Cool Dog

　　The only self-owned brand selling 1.5T four-wheel drive models:

　　What does Haval Cool Dog’s 4×18 multiplication represent? First of all, 4 refers to four-wheel drive. This time, Haval Cool Dog brought us not only the golden power combination of its 1.5T high-power engine and the third-generation 7-speed wet powershift, but also the intelligent and timely four-wheel drive system.

　　Specifically, the Haval Cool Dog inherits the urban off-road gene of the Haval dog category. The intelligent timely four-wheel drive system carried by Cool Dog does not require any operator intervention, and the system monitors the driving state of the wheels in real time and intelligently and dynamically distributes the front and rear axle torques. When a wheel loses its adhesion caused by road icing or sand pit in winter in the city, the four-wheel drive system can still provide stable power output, so as to satisfy the owner’s small willfulness of going out to the wild occasionally.

　　In addition, with the five driving modes of standard, economy, sports, snow and grass gravel, drivers and passengers are given rich options to effectively deal with various road conditions, further improving driving experience and safety guarantee.

　　Relying on the Great Wall Lemon Platform, the chassis performance of Haval Cool Dog has been upgraded in an all-round way. Its approach angle is 24, the departure angle is 26, and the minimum ground clearance is 196mm, which is very close to the approach angle of 24, the departure angle of 30 and the minimum ground clearance of 200mm for big dogs. Such as potholes in Lu Yu, joints between new and old pavements, or the need to get up and down the shoulder when stopping, can effectively avoid the risk of bumping and bottoming.

　　Join hands with JVC to build a luxury car-class music cockpit;

　　In order to create a luxury car-class audio experience, Great Wall Motor and century-old audio and video equipment manufacturer JVC jointly created a unique 4D burning cockpit music experience for Haval Cool Dog.

　　And 18 in 4×18 represents the 18-speaker intelligent sound system carried by the cool dog "4D burning cockpit". Haval Cool Dog has created an omni-directional stereo surround sound field with 18 speakers through 4 treble +2 midrange +1 center +4 bass +1 subwoofer +2 ceiling +2 rear surround +2 headrest speakers. Combined with the rhythm function of the seat, the 64-color atmosphere lamp and the car fragrance system that can rhythm with the music, it brings a four-dimensional immersive experience of hearing, touch, vision and smell.

　　Specifically, Haval Cool Dog is equipped with a 920W 16-channel independent power amplifier, a powerful SOC processing unit and four all-digital amplification chips, which has the characteristics of high efficiency, small distortion and strong anti-interference, ensuring the perfect restoration of high-fidelity sound quality, and supporting the later OTA to create an "evolvable" digital sound system; In terms of speaker design, the high-frequency and intermediate-frequency speakers are designed with strong magnetic NdFeB, which has ultra-high sound pressure, making the sound details richer and the human voice clearer. This laid the "material foundation" for Haval Cool Dog to rival the high-end stereo surround sound of 400,000 luxury cars.

　　It is said that tuning technology is the core to endow the whole sound system with soul. Based on this, after three months of domestic tuning, Haval Cool Dog was airlifted to Europe for testing and more refined debugging and polishing, and finally it was finally completed by an international tuning team composed of dozens of people across China, Japan and Europe and an international R&D team of over 200 people for 12 months.

　　With an excellent sound system, you also need a supporting high-quality experience environment. In fact, in the early stage of product development, Haval Cool Dog took NVH performance as a key topic to study, not just relying on sound insulation cotton to improve NVH performance in the late stage of research and development. It aims at internal damping resonance and external noise, and achieves excellent vehicle-level NVH guarantee on the basis of maintaining its own rigid modeling through front windshield and front double-layer sound insulation glass, powertrain control technology, acoustic package matching technology, air intake system control technology, chassis system control technology and transmission system control technology (four-wheel drive).

　　More than 4X18—-Comfort/Technology/Safety Aspects

　　Comfortable cockpit:

　　With a wheelbase of 2710mm, Haval Cool Dog creates a wider riding space by adopting ultra-short front and rear suspension design, further improving the "car ownership rate" of drivers and passengers.

　　In terms of practical space, there are 29 storage spaces in the car, and a cup holder with different sizes, a double-layer armrest box and a super-large storage space under the shift lever are planned, which fully considers the daily use needs of users.

　　The trunk volume reached 493L, and the space can be expanded to 1298L after the rear row was laid down. It is worth mentioning that, based on the demand consideration of facilitating the daily handling of large items and camping scenes, Haval Cool Dog has created a flat luggage compartment space after being laid down, which, together with the intelligent panoramic skylight of 1.1 square meters in the car, has the taste of "home" for mobile travel.

　　In addition, Haval Cool Dog also intimately planned and standard the cockpit cleaning system and CN95 air conditioning filter. Before the driver and passenger enter the vehicle, they can turn on the corresponding functions in advance through the mobile APP to control the vehicle to automatically turn on the external circulation, which helps to reduce the temperature inside the vehicle in hot summer, and also improves the air quality inside the vehicle.

　　Intelligent technology:

　　As a new car specially built for young people, intelligent technology should naturally not be absent. Whether it is L2 intelligent driving assistance, 12.3-inch multimedia large screen/LCD combination instrument, or 50W super wireless flash charging, intelligent inductive electric tailgate, 360-degree panoramic image and other configurations, Haval cool dog should also be equipped.

　　Specifically, Haval Cool Dog is equipped with L2-level driver assistance system, which can realize ACC, AEB, traffic sign recognition, speeding alarm and other functions through 19 detection units including 12 ultrasonic radars, 4 high-definition 360 cameras, 2 millimeter-wave radars and 1 intelligent forward-looking camera.

　　Haval Cool Dog also comes standard with a 12.3-inch LCD combination instrument with a resolution of 1920*720 and a 12.3-inch multimedia large screen, which can realize dual-screen linkage. In addition, Haval Cool Dog comes standard with a super wireless flash charging of up to 50W, which can save more than 60% time from 0 to full state compared with the mainstream wireless charging of 15W on the market, and the efficiency is obviously improved.

　　The appearance of intelligent inductive electric tailgate, Bluetooth key of smart phone, 360-degree panoramic image and even transparent chassis has improved the comfort and convenience of car use.

　　Security guard:

　　In terms of safety, the cool dog comes standard with 6 airbags including main and auxiliary airbags, side airbags and front and rear integrated side air curtains; The proportion of high-strength steel in the cool dog body is over 75%, among which the proportion of ultra-high-strength steel and thermoformed steel with greater strength is 41%. In case of danger, passengers can be effectively protected through high-strength body and reasonable force transmission channel.

　　Summary:Courage is nature. The appearance of Haval Cool Dog, which is born of music and speaks for young people, will surely bring a brand-new choice to Z generation consumers who dare to enjoy themselves and innovate.
