Nissan is a popular compact car in the domestic automobile market, but some car maintenance masters do not recommend buying this car. Then, why doesn’t the car maintenance master recommend buying Nissan Sylphy? Let’s analyze it below.

First of all, Nissan Sylphy’s power performance is average. Although Nissan Sylphy is equipped with 1.6-liter and 1.8-liter naturally aspirated engines, its power performance is not particularly excellent. Especially when driving at high speed, the engine is noisy and the acceleration is not very rapid. In addition, there are some problems in the gearbox of Nissan Sylphy, such as unstable shifting and abnormal noise.

Secondly, the body structure of Nissan Sylphy is relatively fragile. Although the body of Nissan Sylphy adopts advanced structural design, its score is not very high in the crash test. This also shows that its body structure is relatively fragile. If there is a collision accident, the owner needs to bear higher maintenance costs.

Third, the maintenance cost of Nissan Sylphy is high. Most parts of Nissan Sylphy can be repaired independently. However, due to its advanced engine and gearbox technology, more professional equipment and technology are needed for maintenance, which leads to relatively high maintenance costs. In addition, due to the relatively small sales volume of Nissan Sylphy, there may be a shortage of spare parts during maintenance, which will also lead to an increase in maintenance costs.

Finally, the safety performance of Nissan Sylphy needs to be improved. Although Nissan Sylphy got a high evaluation in the crash test, in actual use, some car owners reported that its safety performance needs to be improved. For example, Nissan Sylphy is prone to elegant phenomenon when driving at high speed, and its braking distance is relatively long, which is a big safety hazard for drivers.

To sum up, although Nissan Sylphy is a popular compact car, its power performance is average, its body structure is fragile, its maintenance cost is high and its safety performance needs to be improved. Therefore, it is reasonable that the automobile maintenance master does not recommend buying Nissan Sylphy. Of course, the specific car purchase needs to be comprehensively considered according to its own needs and actual situation.

Original title: Let "Smart Car" Drive on "Smart Road" —— Excerpts from some guests’ speeches at the high-end seminar on infrastructure and application scenarios of "Car-Lu Yun Integration"

On the afternoon of September 22nd, 2024 China New Energy Auto Parts Fair held a high-end seminar on the infrastructure and application scenarios of "Vehicle-Lu Yun Integration". More than 100 executives from Internet and automobile companies and industry experts and scholars from all over the country gathered together to jointly describe the bright future of "car-Lu Yun integration". Some guest speeches are summarized as follows:

We should be brave in innovation to promote the integration of vehicles and Lu Yun.

Zhao Zesheng, a distinguished expert of China Electric Vehicle committee of 100 Intelligent Network Research Institute.

At present, intelligent networked vehicles are accelerating the deep integration of the automobile industry with high-precision positioning, electronic information, artificial intelligence, big data, cloud computing, blockchain and other industries, becoming a new quality productivity.

Intelligent networked vehicles are accelerating the integration with transportation, communication, energy, computing and other fields, and its essence is the technical route of "integration of vehicles and Lu Yun". At present, in the pilot construction of promoting the coordinated development of smart city infrastructure and intelligent networked vehicles, there are widespread problems such as disunity of system architecture, "fragmentation" of infrastructure construction, disunity of signal transmission and data standards, and lack of "hematopoietic recovery" ability of operators.

To further promote the integration of vehicles and Lu Yun, we should be brave in innovation, implement the unification and coordination of policies, technologies and standards in accordance with the development plan and top-level design of the integration of vehicles and Lu Yun in each city, define the medium-and long-term goals and phased tasks, and promote the large-scale application of the integration of vehicles and Lu Yun with the construction strategy of "standards first-distributed construction-continuous iteration", and finally realize commercial operation. At the same time, further clarify the main body of the "vehicle-Lu Yun integration" system, and realize the global facility coverage and global, large-scale and commercial scene application.

C-V2X vehicle networking technology empowers the coordinated development of vehicle, road and cloud.

Chen Shanzhi, Director of National Engineering Research Center for Mobile Communication and Vehicle Networking

By integrating vehicles, roads and cloud computing, the "Vehicle-Lu Yun Integration" system realizes real-time road monitoring, vehicle independent decision-making and cloud collaborative management, which significantly improves driving safety and efficiency.

At present, China’s automobile industry is accelerating the transformation to new energy intelligent networking. Relying on the C-V2X car networking technology, China has established an intelligent networked car China scheme integrating "car and Lu Yun". In the future, the collaborative development model of "smart car+smart road+collaborative cloud" will become a new business model and contribute to Chinese modernization.

Shiyan was selected as the pilot city of the national intelligent networked automobile "car-Lu Yun integration" application, and the new energy and intelligent networked automobile industry ushered in new development opportunities and challenges. It is suggested to build intelligent roadside infrastructure with wide coverage, establish a city-level service management platform, improve the assembly rate of vehicle terminals, and carry out large-scale demonstration applications. We will make every effort to build an intelligent networked automobile city-level global test environment, attract more models to settle in for testing, attract more upstream and downstream enterprises in the industrial chain to settle down, and promote the automobile industry chain, supply chain and value chain to move towards the high end.

"Car-Lu Yun integration" brings new opportunities for development

Zhang Ran Mao, General Manager of Unicom Zhiwang Technology Co., Ltd.

At present, automobile intelligence and networking are rapidly entering a new stage of integration and scale development, and it is urgent to build a heterogeneous, distributed, safe and reliable information infrastructure and provide an industry solution that can be operated, managed online and integrated with cloud and network.

As a new opportunity for the new energy industry, "Vehicle-Lu Yun Integration" integrates vehicle, road and cloud elements to form a perception, decision-making and control system, which brings new growth points and development opportunities for the new energy automobile industry. The development of intelligent networked automobile industry is the strategic mission of "car-Lu Yun integration", "single city penetration+scale effect" is an important feature of integration, and "building a three-level cloud control platform system" is the core task of integration.

To promote the integration of vehicles and Lu Yun, Shiyan needs to strengthen the top-level design, set up an intelligent networking industry promotion leading group, clarify the main body of municipal construction and operation, start the research and development of vehicles and equipment subsidies, and at the same time quickly build a C-V2X scale service network, build a commercial vehicle "vehicle-Lu Yun integration" pilot, and build an industrial ecological highland of intelligent networking of commercial vehicles.

The whole industry promotes the "integration of vehicles and Lu Yun"

Huang Gang, General Manager of China Mobile Zhixing Network Technology Co., Ltd.

"Integration of vehicles and Lu Yun" is conducive to the unification of vehicle-road cooperative construction standards, large-scale application practice and exploration of business models. After the city has completed the construction of "integration of vehicles and Lu Yun", every vehicle and everyone on the road can enjoy the benefits of more efficient, less congested and safer traffic.

To promote the pilot construction of "car-Lu Yun integration", it is necessary to further open and interoperate the urban stock data. In the early construction process, the city has accumulated a large number of data assets. Opening these data is very beneficial to the application of "vehicle-Lu Yun integration" and reducing the cost of repeated construction. At the same time, it is suggested to promote the systematic construction of safety. The security challenges of the Internet of Vehicles are all-round, including platform security, application security, data security, etc. It is necessary to carry out overall planning of the industry and form a systematic construction to lay a good foundation for promoting the commercial development of Cheluyun. At the same time, it is necessary to explore flexible modes of operation participation and business return, strive for more industry entities to participate, give full play to their advantages, promote together, and improve operational efficiency. For enterprises operating in pilot cities, they can give strong support in investment and financing, science and technology fund, taxation, talent protection and so on.

Effectively let the data "run in front of the car"

Xiang Yunfeng, General Manager of Shiyan Big Data Operation Co., Ltd.

"Vehicle-Lu Yun Integration" equips roads with advanced communication and sensing technology infrastructure, and then uploads the real-time collected road information to the cloud platform through networking technology. After comprehensive analysis of the collected road and vehicle information, the cloud platform feeds back the driving decision suggestions to the intelligent vehicles, and connects the roads, vehicles and the cloud platform, thus achieving a breakthrough in the networking technology of intelligent and automatic driving. Among them, data is an important driving factor for the sustainability of "car-Lu Yun integration", and Cheluyun can further converge the data.

The operation of "car-Lu Yun integration" network connection mode is inseparable from the sharing and collection of big data. It is necessary to fully break down the information barrier, pay attention to the construction and interoperability of information ports, and truly let the data "run in front of the car" and play the role of system guidance and deployment.

Shiyan Big Data Company has a unique resource advantage. At present, it plans to take the Central Business District as a roadside pilot, start from the original design, and gradually realize the global coverage, and strive to play a data role in the construction of a pilot city with the application of "car-Lu Yun integration".

Vigorously carry out the commercial operation of intelligent network connection

Shi Yong, founder of Beijing Xingyun Internet Company

"Car-Lu Yun integration" scheme gives China a first-Mover advantage. Under the path of "vehicle-Lu Yun integration", the coordinated operation between vehicles and roads can be realized, the traffic operation can be accurately controlled and optimized as a whole, and the traffic safety factor and traffic efficiency can be greatly improved.

At present, the road infrastructure construction of intelligent networking is "highly leveraged", difficult to operate and maintain, lacking commercial operation, and has not formed a scale effect. To promote the large-scale application practice of "vehicle-Lu Yun integration", it is necessary to further reduce costs and increase efficiency, and the government needs to invest in road infrastructure reconstruction, guide enterprises to actively explore the commercial operation mode of intelligent network connection, and form capital requirements such as operating hematopoiesis ability and feeding back roadside equipment maintenance and technology upgrading. At the same time, encourage and guide social capital and industry enterprises to actively participate. In addition, the government should speed up the introduction of relevant subsidy and incentive policies to encourage the increase of vehicle penetration.

For more than ten years, Nebula Internet has been rooted in the field of C-V2X and has rich experience. I hope to contribute to the construction of Shiyan Intelligent Networked Automobile "Car-Lu Yun Integration" application pilot city.

Large-scale model and integration of "car-Lu Yun integration"

Professor Li Ming, School of Computer Science, Wuhan University

In the past six months, the iterative curve of artificial intelligence large model technology has slowed down. The fundamental reason for this phenomenon is that there is a shortage of computing power and data supply all over the world, especially the data scale has fallen into a great bottleneck. When the machine is not full, the performance output side of the large model cannot complete high-quality output. Traffic is a very typical process from perception and cognition to decision-making and control. At present, artificial intelligence only presents fragmented application in traffic. To really solve the problem, it is necessary to use the line of large model to connect all scattered points such as traffic flow, roads and traffic signals in series, and carry out intelligent collaboration on key traffic nodes such as cars, roads, clouds and networks. The big model can identify road conditions and detect traffic density. At the same time, it can realize the dynamic optimization of traffic system by integrating and dispatching various intelligent services such as vehicle supervision, traffic signal adjustment, intelligent navigation and intelligent parking. With the deep roots of the big model in various industries, it will form a joint force with the "car-Lu Yun integration" and paint a brand-new future-oriented picture for people’s transportation.

Actively explore the application of automatic driving of commercial vehicles

Zhai Jun, Chairman of Wanji Technology

The development of "car-Lu Yun integration" is the key to promote the large-scale industrial application of intelligent networked cars. China’s intelligent networked automobile industry has a strong momentum of development, and the popularization of networked automobile industry has accelerated. The "integration of automobile and Lu Yun" has promoted the formation of a double closed loop of data and intelligence, intelligent service and governance, completed industrial agglomeration, and injected new kinetic energy into urban development.

Shiyan is a typical mountain city, with narrow roads, many bends and large slopes. Due to geographical conditions, it is necessary to adopt roadside equipment layout methods and sensing algorithms suitable for mountain roads in infrastructure construction. Shiyan is one of the earliest cities in China to develop new energy automobile industry. At present, focusing on "new energy" and "intelligent networking", we should focus on the application of automatic driving of commercial vehicles, explore a number of vehicle-road cooperative application scenarios suitable for automatic driving in mountainous towns, and at the same time, carry out networking transformation on existing vehicles to make them have the ability of intelligent networking information interaction. Driven by the high-value application of "small scene and small incision", we will promote the application of "car-Lu Yun integration" and contribute to the construction of "car-Lu Yun integration" in mountainous cities.

Adhere to the road of integration of intelligence and electricity development

Zhang Zhengyuan, Vice President of Sailisi Group Co., Ltd.

In 2003, Cyrus made a joint venture with Dongfeng Company to produce automobiles, and worked hand in hand with Shiyan for more than 20 years. Cyrus has always firmly adhered to the road of intelligent and electric integration under the software-defined automobile, insisting that electrification is the carrier of intelligence and intelligence is the soul of electrification. Actively explore intelligent networked automobile solutions, carry out cross-border integrated automobile business with Huawei, and launch luxury intelligent electric vehicles. Among them, the super-intelligent platform-Cyrus Rubik’s Cube Platform, which is independently innovated by enterprises and has the ability of ever-changing and continuous evolution, takes "panoramic security, multi-power, ever-changing space and intelligent guidance" as its core features to realize cross-domain integration of security, power, chassis and software. Celestial M9′ s "intelligent driving without map" technology does not rely on high-precision maps. Through laser radar and advanced perception network, vehicles can perceive the surrounding environment more comprehensively and improve safety. "Car-Lu Yun Integration" pays more attention to the standardization and safety management of the industry, and provides support for the long-term development of smart cars. The two complement each other and jointly promote the technological progress and healthy development of smart cars. (Reporter Ji Fengbo Meng Jianjin Pan Shixin)

In July this year, a car owner bought a Maibakh with a huge sum of money, which was a happy event.

However, problems followed, and the owner found that there was abnormal noise in the central control, and found that the A-pillar of the co-pilot had water leakage when it rained.

In this regard, the owner negotiated with the 4S shop and checked many times, but did not find the specific reason for the water leakage failure.

Therefore, the owner doesn’t want this car and wants to replace it with a new one by paying money, but the loss plan given by the 4S shop far exceeds the owner’s estimate.

This made the problem not solved in time.

In the absence of rights protection, the owner posted a three-color canopy for the car and sent a video.

There will be a super distinctive "three-color awning Maibakh".

It is extremely ironic that millions of people in Maibakh can’t "shelter from the wind and rain", but they use dozens of awnings to "shelter from the wind and rain".

As a result, 4S stores have to pay attention to it, and relevant parties have indicated that they should actively deal with this matter. After all, millions of luxury cars can’t "bow down" in front of dozens of awnings!

The last thing to say is that the water leakage of the car is not within the scope of three guarantees, which is really not as good as dozens of awnings!
