The International Telecommunication Union (ITU) has defined three major application scenarios of 5G, namely, Enhanced Mobile Broadband (eMBB), Ultra-high Reliability and Low Delay Communication (uRLLC) and Mass Machine Communication (mMTC). Among them, ultra-high reliability and low delay communication (uRLLC) technology is the key to realize the 5G vehicle networking.
In the early days, DSRC technology and LTE-V technology were used to realize vehicle external communication, which had the shortcomings of short transmission distance or prolonged transmission time. As the evolution of LTE technology, the 5G car networking not only shortens the time delay to 1ms, but also has a higher bandwidth, supports a larger number of connections, and supports a higher moving speed.
It can be said that there is no real car networking without 5 G. Of course, without the Internet of Vehicles, 5G will also lose an important usage scenario.
The "Proposal" pointed out that the five elements of "car, road, cloud, network and map" will be used to jointly promote innovation capacity building and build the overall advantages of Beijing intelligent networked automobile industry chain; Establish a set of test and demonstration application system, form a benign interaction between R&D, production, service and application, and promote the accelerated development of intelligent networked automobile industry and new transportation service system.
Among them, it is required that the 2022 Winter Olympics will realize the comprehensive application of intelligent networked vehicles, accelerate the pace of technological breakthroughs and product research and development, accelerate the entry of new technologies and new cars, enhance practical capabilities, improve technical standards, application standards and safety standards, and basically complete the construction of intelligent networked vehicles technology system. The medium-and long-term development goal is to form a world-class intelligent networked automobile industry cluster through continuous iterative upgrading for 20 years, to create a new intelligent transportation mode with deep integration of intelligent networked automobile and intelligent transportation, and to build the most dynamic autonomous driving innovation ecosystem and a "safe, efficient, green and civilized" intelligent networked automobile society.
Fengshen AX7 Mach Edition is an answer sheet handed over by Dongfeng Shen Feng. As a brand-new member of Shen Feng AX7 car series, Shen Feng AX7 Mach Edition is not only more radical than Shen Feng AX7 PRO in appearance, but also more excellent in scientific and technological content with the blessing of 5G technology and WindLink 6.0 artificial intelligence vehicle system.
Shen Feng AX7 Mach version interior upgrades the size of the central control panel to 12.3 inches, which is the same as the full LCD instrument panel. The color matching of the interior with dark color also increases the scientific and technological atmosphere of the interior.
12.3-inch central control large screen adopts floating design and horizontal layout, and the brand-new WindLink 6.0 artificial intelligence vehicle system has been further strengthened in response speed and function.
The next thing I want to talk about is the highlight of WindLink 6.0-multi-scene mode. Simply put, the passengers in the car can directly press the central control screen, and the vehicle will adjust the air conditioner and sunroof according to the preset to make it conform to the selected scene state, without step-by-step operation.
Its voice assistants are also deeply customized with the major service providers in Dongfeng Shen Feng, enabling it to do things that other brand voice assistants can't do. Including but not limited to Chinese-English translation, mathematical calculation, schedule management, take-away, hotel reservation, etc. , it may add more functions to the in-vehicle system through OTA upgrade.
With the passage of time, it is not out of reach to break the "wall" between all service providers. On that day, when you get on the bus, just say "I want to go to Chengdu Panda Base" and confirm, then your car will start the automatic driving mode, and you will embark on the road to Chengdu Panda Base. Moreover, to buy tickets through the Internet and book parking spaces at the same time, all you have to do is look at the gameplay strategy on the central control screen. This is a real scene service based on the 5G car networking. Now, in the Shen Feng AX7 Mach version, we can already see the prototype.
In other functions, WindLink 6.0 also performed very well. Online audio sources support a variety of popular apps, which can be directly operated by voice assistants. The online map navigation function is basically the same as the mobile App. In addition to real-time query of road conditions, users can also manually enter the license plate number and avoid the restricted area when planning the route. The brand-new CCTV voice and car KTV, with the blessing of 5G network, bring a brand-new audio-visual entertainment experience.
In addition, the Mach version of AX7 also supports the remote control of mobile App, which can realize the remote start/close of engines, air conditioners, lighting and other equipment, as well as the opening and closing of windows, skylights and trunk. In addition, through the App, you can also realize functions such as maintenance reservation, car traffic purchase, violation inquiry, car condition inquiry, and navigation destination distribution. , which basically covers most daily travel scenarios.
In addition, it must be mentioned that the "China Heart" top ten engine Dongfeng Mach Power 1.5T engine on the AX7 Mach version is a new generation of turbocharged direct injection engine developed by Dongfeng based on the concept of platformization and modularization, with maximum power 140kW, maximum torque of 300n·m and maximum thermal efficiency of 41.000 per 100 kilometers.
The engine adopts efficient anti-explosion and rapid combustion system, deep friction reduction technology and intelligent and efficient thermal management technology. The combustion system integrates Atkinson cycle, 350bar high pressure injection system, high tumble ratio intake and high compression ratio combustion chamber, low inertia and high efficiency electronic control supercharging system, high pressure cooling EGR and other technologies. The three technical packages greatly improve the power performance and fuel economy of the engine, and the power performance is rapid.
At present, the maximum thermal efficiency of the same class engine is basically maintained at about 35%, and the maximum thermal efficiency of the AX7 Mach version engine of 4 1.07% stands out from the crowd. What does such high thermal efficiency mean? Simply put, it is more fuel-efficient when the power is similar.
It is equipped with I-Driving Fun-Intelligent ECU, which can automatically identify the car scene and the user's driving habits, so as to select the optimal driving mode, provide pleasant linear pyloric reaction and shift experience, enhance the user's driving experience in various scenes, and achieve a good balance between power and energy saving.
One of the most important points is that Dongfeng uses a self-developed EMS system, and the software strategy is developed according to the needs of the whole engine (even the whole vehicle). The matching degree of each component is higher, which can further improve the thermal efficiency of the whole machine.
This is different from the transition from 4G to 5G, which is faster but more expensive. But the Mach version of the AX7 engine is faster, but more economical.
Just like the "DF" in its configuration name, the AX7 Mach version has finally reached the leading level in technology and performance through the unremitting efforts of several generations of China automobile workers, which gives us enough confidence and also gives China automobile industry enough confidence.
Summary: I don't know what the future intelligent networked car can achieve, because today's technological development has exceeded our imagination. The scenes in those sci-fi films are slowly being realized, and as consumers, what we need to do is to enjoy the feast of the 5G era. For example, let's start with the Mach version of Dongfeng Shen Feng AX7.
