The factory official map shows the internal structure of the red flag H9! There is also a demonstration of new energy technology!

[car home? Technology]? For too many years, the brand impression of Red Flag always revolves around the feeling of solemnity, seriousness and being aloof. Until the listing of Red Flag H5 two years ago, the dynamic body lines completely broke the previous customary impression, and then new models came one after another like mushrooms after rain. In addition to our most perceptive styling design, there are many other "black technology" research and development of Red Flag Car, all of which come from a big warm nest called NBD, which is located in the southwest of Changchun, and its location is easy to remember. The name of the road at the door is called Xinqi Street.

○? NBD, the grand planning of Hongqi in new energy technology, is short for the new research institute of FAW R&D General Institute. From the architectural style, it can be felt that it is related to innovation. Walking into this 51,-square-meter building, it feels like a brand-new terminal building, in which styling design institute, new energy development institute, intelligent network 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 have been exposed are bred here.

what are the motivations for the future red flag? In different countries, the general planning of automobile energy route is in the same direction, and the methods are slightly different. In Europe, the technical route of 48V weak hybrid and pure electric is more; Japanese still adhere 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 line. Therefore, if China brand cars want to be strong in the power system, they must reduce the constraints 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: Breaking the "two fields" barrier, Toyota and Honda have always been label companies of hybrid technology. However, China brand car companies have also made technological breakthroughs in hybrid technology before. FAW's current hybrid system adopts a dual-motor scheme, and the position relationship of generator speed-regulating motors is a plane layout, which reduces the horizontal space of the whole system and is conducive to meeting the needs of different levels of engine room layout. It is reported that the maximum power of the motor is 14kW. ? The matching power battery system adopts ternary lithium scheme, which consists of 48 modules connected in parallel, with a total capacity of 1.75kWh. Like the mainstream HEV hybrid vehicles at present, the battery is air-cooled.

The hydrogen fuel plan will be put in place in two years. At present, there are not many vehicle companies focusing on the research and development of hydrogen fuel cells, and the stack technology is the absolute core. At first, the hydrogen fuel cell used in automobiles adopted the scheme of ink bipolar plate supporting the stack. In order to improve the energy efficiency, low-temperature starting performance and cost, after years of research and development, Toyota applied the metal bipolar plate stack to automobile power for the first time in 214. According to experts in this field, the application of hydrogen fuel cells in automobiles started relatively late in China, 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 stack in the field of hydrogen fuel cells. For mass production of automobiles, besides energy efficiency and safety technology, there are still many issues that need to be solved around the requirements of vehicle regulations. For example, the use environment of automobiles is complex, and the problem of cold start at low temperature in winter will affect the feasibility of mass production. It is reported that FAW has achieved rapid start at MINUS 3 degrees and maintained the normal work of hydrogen fuel power during the test. When I asked about this suitable mass production, the answer was that a demonstration operation might be carried out around the Winter Olympics in two years. However, the real hydrogen fuel vehicle technology is of more strategic significance at this stage. Hydrogen production, storage, transportation, filling and cost are all difficult problems in front of this seemingly ideal automobile energy chain.

○FME platform: future-oriented pure electric platform With the recent landing of a series of self-driving taxi projects, L4-class self-driving technology is gradually maturing. As a future-oriented vehicle platform, we must take into account the hardware foundation for 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 to be used as 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 battery capacity of this platform ranges from 85kWh to 12kWh, and the maximum cruising range can reach 7km, which can be said to be the first echelon of the cruising range of pure electric vehicles. Secondly, this platform is equipped with FEEA2. electronic architecture, compared with the previously 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 the very large data transmission in the automatic driving function. In addition, as a self-driving car, safety is always the first demand, so the braking and steering devices on the FME platform, which are related to the life safety of passengers, have redundant systems.

○ The large screen in the medium-free holographic interactive car seems to have become the admission ticket for the smart car, and there is no such thing as losing several copies subjectively for a screen larger than ten inches. After that, the sense of quality and innovation of interior design will come from this. In the HIL(Hardware? In? the? Loop, there are some interesting small projects in the R&D department. The holographic two-dimensional villain on Pentium T77 was born in this department. In addition, we have all seen a lot of sci-fi movies. In the bridge section, there are often shots in which you slide the virtual interface in the holographic image in the air to control the overall situation. In the HIL department, there is a display with similar effect. What do you think if you can adjust the air volume of the air conditioner by hand in the interface suspended in the air? However, the focus of these innovations is to improve the safety and humanization of human-vehicle interaction.

○? The 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? At that time, the official map only showed some transformation scenes of the factory. This time, although photos are not allowed on site, and we have introduced the general situation of the factory before, this time I saw not only the production line with the red flag H9, but more importantly, we saw some internal structures of the red flag H9 in the official map, especially the chassis part, which can be regarded as the first time. Supposedly, this is nothing new, but when I turned to the picture of the chassis of Hongqi H9, I was shocked. On a certain level, I think the red flag has finally "enlightened", made the gas field we expected, and bid farewell to the past, which is very "circled". Of course, just having a good design is not enough to be called advanced. After all, it has already shown the positioning of "new nobleness". If Hongqi wants to stand on its feet, it must take some real skills. There are not many models of all-aluminum subframe before and after use these days, but since the positioning tone is already very high, it is not surprising to use all-aluminum subframe. According to the official, after welding the subframe with self-designed aluminum profiles, the position of the subframe can be reduced by 3%. It can be seen that Hongqi H9 not only makes great momentum in design, but also belongs to the top level in China brand in terms of materials and structure, which has both light weight and structural advantages, and is very cost-effective.

○? Editor's comment: From the pictures revealed by Hongqi H9 chassis, we can be sure that Hongqi H9 has put a lot of efforts into the chassis, both in materials and structure, and the hardware level is very strong at the same price. In terms of new energy technologies, Hongqi has shown us a grand blueprint: making full efforts in pure electric, hybrid and fuel cell technologies, which is amazing in terms of performance indicators, and how the actual performance is. Let us still expect these technologies to be loaded and landed as soon as possible. (text/map? Car home? Wang Miao? Shu Ning? Photo? Red flag official photography)
