The factory official map shows the internal structure of the red flag H9! There are also demonstrations of new energy technologies!

[car home? Technology]? For too many years, the brand impression of Hongqi has always revolved around the feeling of solemnity, seriousness and detachment. Until the listing of Red Flag H5 two years ago, the dynamic body lines completely broke the previous habit impression, and then new models mushroomed one after another. In addition to our most perceptive styling design, Red Flag has many other "black technology" R&D, all from a big warm nest called NBD in the southwest of Changchun, and the location is easy to remember. The name of the road at the door is Qi Xin Street.

○? Hongqi's grand plan of new energy technology

NBD, the abbreviation of the new research institute of FAW R&D Research Institute, can be felt to be related to innovation from the architectural style. Walking into this 565438+100000 square meter building, it feels like a brand-new terminal building. The styling design institute, new energy development institute, intelligent networking development institute, materials and lightweight research institute, Pentium development institute and commercial vehicle development institute are all concentrated here, and many new cars that have just been listed and exposed are bred here.

What is the motivation of the future red flag?

In different countries, the overall planning of automobile energy routes is in the same direction, and the methods are slightly different. In Europe, there are more technical routes of 48V weak hybrid pure electric; Japan still adheres to the HEV light hybrid route, and plug-in hybrid technology is more exported to overseas markets; Under the guidance of emission policy, China brand takes plug-in hybrid and pure circuit route. Therefore, if China brand cars want to be strong in the power system, they must reduce the bondage of high-barrier technology. At present, FAW and Hongqi Automobile have started to simultaneously develop new energy technology solutions such as hybrid, pure electric and hydrogen fuel cells.

Dual-motor Hybrid Power: Breaking the Barriers of "Two Fields"

Toyota and Honda have always been label companies of hybrid technology, but China brand car companies have made technological breakthroughs in hybrid technology before. At present, the hybrid power system of FAW adopts the dual-motor scheme, and the position relationship of generator speed-regulating motors is plane layout, which reduces the lateral space of the whole system and is beneficial to meet the requirements of engine room layout at different levels. The official declared that the maximum power of the motor is 140kW, and learned that this dual-motor hybrid system will be first applied to HS9 models. ? The matching power battery system adopts ternary lithium scheme, which consists of 48 modules in parallel, with a total capacity of 1.75kWh. Like the mainstream HEV hybrid vehicle at present, the battery is air-cooled.

The hydrogen fuel plan will be in place within two years.

At present, there are not many vehicle companies focusing on the research and development of hydrogen fuel cells, and stack technology is the absolute core. At first, hydrogen fuel cells used in automobiles used ink bipolar plates to support the stack. In order to improve energy efficiency, low-temperature starting performance and cost, Toyota applied metal bipolar plate stack to automobile power for the first time on 20 14 after years of research and development. According to experts in this field, the application of hydrogen fuel cells in automobiles in China started late, and there are still many topics to catch up with in hydrogen fuel cell technology.

FAW is currently promoting the research and development of metal bipolar stacks in the field of hydrogen fuel cells. For mass production of automobiles, besides energy efficiency and safety technology, there are still many problems to be solved around the requirements of vehicle regulations. For example, the automobile use environment is complex, and the problem of cold start in winter will affect the feasibility of mass production. It is reported that FAW has achieved a rapid start at MINUS 30 degrees and kept the hydrogen fuel power working normally during the test.

When I asked about this suitable mass production, the answer was that a demonstration operation might be conducted around the Winter Olympics in two years. But the real hydrogen fuel vehicle technology is more strategic at this stage. The production, storage, transportation, filling and cost of hydrogen are all difficult problems in front of this seemingly ideal automobile energy chain.

○FME platform: a pure electric platform for the future

With the recent landing of a series of self-driving taxi projects, L4 self-driving technology is gradually maturing. As a future-oriented vehicle platform, we must consider the hardware foundation of automatic driving adaptation. Because the control system of pure electric vehicle is relatively simple, and the control chips are not as many as those of traditional fuel vehicles, it has natural advantages as an L4 self-driving vehicle.

To this end, Hongqi Automobile launched the FME electric intelligent networking technology platform. First of all, from the technical indicators, the power battery capacity of the platform ranges from 85kWh to 120kWh, and the maximum cruising range can reach 700km, which can be said to be the first echelon of the cruising range of pure electric vehicles.

Secondly, this platform is equipped with FEEA2.0 electronic architecture, compared with the widely used CAN? Bus communication bus technology, this electronic architecture can carry higher data transmission speed and bandwidth, so it can cope with various driving assistance functions, even very large data transmission in automatic driving functions. In addition, as a self-driving car, safety is always the first requirement, so the braking and steering devices related to the safety of passengers on the FME platform have redundant systems.

○ modeless holographic interaction

The big screen in the car seems to have become a ticket for smart cars. No screen larger than ten inches will lose a few copies subjectively. After that, the quality and innovation of interior design will come from this, in HIL (hardware? Are you online? That? Cycle, there are some interesting small projects in the R&D department. The holographic two-dimensional villain on Pentium T77 was born in this department. Besides, we have all seen many sci-fi movies. In the bridge part, you often slide the virtual interface in the hologram in the air to control the global lens. In HIL department store, there is also a display with similar effect. What do you think if you can adjust the air volume of the air conditioner by hand on the interface suspended in the air? However, the focus of these innovations is to improve the safety and humanization of human-vehicle interaction.

○? Official map "cloud" chassis, this hardware is really capped.

Some time ago, we made a simple analysis of the new Hongqi factory (Hongqi new factory? The official map at that time only showed some transformation scenes of the factory. Although it is not allowed to take photos on site this time, and we have also introduced the general situation of the factory before, this time I saw not only the production line of Hongqi H9, but more importantly, I saw some internal structures of Hongqi H9 in the official map, especially the chassis part, which is the first time. Supposedly, this is nothing new, but when I turned to the chassis picture of Hongqi H9, I was shocked.

On a certain level, I think the red flag has finally "enlightened", made the gas field we expected, bid farewell to the past, and it is very "circle". Of course, just having a good design is not enough to call it advanced. After all, it has shown the positioning of "new nobility". If the red flag wants to gain a foothold, it must show some real skills.

There are not many models used before and after the all-aluminum subframe these days, but since the positioning sound is already very high, it is not surprising to use the all-aluminum subframe. According to the official, the position of the subframe can be reduced by 30% after welding the subframe with self-designed aluminum profiles.

It can be seen that Hongqi H9 is not only imposing in design, but also among the top brands in China in terms of materials and structure. It has both lightweight and structural advantages, and its cost performance is very high.

○? Editor's comment:

From the pictures disclosed in the chassis of Hongqi H9, it can be confirmed that Hongqi H9 has put a lot of effort into the chassis, with excellent materials and structure, and strong hardware level at the same price. In terms of new energy technology, Hongqi shows us a grand blueprint: go all out in pure electric, hybrid and fuel cell technologies, which is amazing in terms of performance indicators and how it actually performs. Let's expect these technologies to load and land as soon as possible. (text/map? Car home? Wang Miao? Shu Ning? Photos? Red flag official photography)
