[Autohome?Technology]?For too many years, the brand impression of Hongqi has always revolved around a solemn, serious, and aloof feeling. Until the Hongqi H5 was launched two years ago, the dynamic body lines were completely Breaking the previous impression, new models have sprung up one after another. In addition to the styling design that we perceive most, Hongqi cars also have many other "black technologies" research and development, all of which come from a big warm nest called NBD. It is located in the southwest of Changchun. The location is easy to remember. The door at the door The name of the road is New Hongqi Street.
○? Hongqi’s grand plan for new energy technology, NBD, is the abbreviation of the new FAW R&D Institute. You can feel its connection with innovation from the architectural style. Walking into this 510,000-square-meter building It feels like we have arrived at a brand-new terminal building in Da Building, among which the Design Institute, New Energy Development Institute, Intelligent Network Development Institute, Materials and Lightweight Research Institute, Pentium Development Institute, Commercial Vehicle Development Institute, etc. are all concentrated here. Just now Many of the H9 on the market and new cars that have been exposed in various pictures were conceived here.
What are the motivations for future red flags? Different countries have the same direction and slightly different approaches to the large-scale planning of automobile energy routes. Europe is more on the 48V weak hybrid and pure electric technical routes; the Japanese are more on the HEV light hybrid route, plug-in Hybrid technology is mostly exported to overseas markets; while Chinese brands, guided by emission policies, are taking plug-in hybrid and pure electric routes. Therefore, if Chinese brand cars want to strengthen their power systems, they must reduce the constraints of high-barrier technologies. At present, FAW and Hongqi Motors have begun to simultaneously develop new energy technology solutions such as hybrid, pure electric, and hydrogen fuel cells.
Dual-motor hybrid: breaking the "Two-Tian" barrier. Toyota and Honda have always been hybrid technology label companies, but Chinese brand car companies have also avoided Shuangtian's patents in hybrid technology. There has been a technological breakthrough. FAW's current hybrid system adopts a dual-motor solution. The positional relationship between the generator speed-regulating motor is a planar layout. This reduces the lateral space of the entire system and is conducive to adapting to different levels of cabin layout requirements. , the official claimed that the maximum power of the motor is 140kW. It is reported that this dual-motor hybrid system will be first applied to the HS9 model. ?The matching power battery system uses a ternary lithium solution, consisting of 48 modules connected in parallel, with a total capacity of 1.75kWh. Like the current mainstream HEV hybrid models, the battery adopts an air-cooling design.
The hydrogen fuel plan will be in place in two years. Currently, there are not many vehicle companies focusing on hydrogen fuel cell research and development, and stack technology is the absolute core. Initially, the hydrogen fuel cell used in automobiles used a solution in which ink bipolar plates support the stack. In order to improve energy efficiency, low-temperature starting performance and cost, after years of research and development, Toyota first introduced it in 2014. Metal bipolar plate stacks are used in automobile power. According to the opinions of experts in this field, the application of hydrogen fuel cells in automobiles has started relatively late in China, and there are still many issues to catch up in hydrogen fuel cell technology. FAW is currently promoting the research and development of metal bipolar plate stacks in the field of hydrogen fuel cells. For mass production of automobiles, in addition to energy efficiency and safety technology, there are also many issues surrounding vehicle regulatory requirements that need to be overcome, such as the vehicle usage environment. Complex, the problem of cold start under low temperature conditions in winter will affect the feasibility of mass production. It is reported that FAW has achieved rapid start in an environment of minus 30 degrees during testing and maintained normal operation of hydrogen fuel power. When I asked whether this would be suitable for mass production, the answer was that it might be put into demonstration operation around the Winter Olympics in two years. However, the real hydrogen fuel vehicle technology is of greater strategic significance at this stage. Hydrogen production, storage, transportation, refueling, cost, etc. are all difficult problems facing this seemingly ideal automotive energy chain.
○FME Platform: A pure electric platform for the future. With the recent implementation of a series of autonomous taxi projects, L4 autonomous driving technology is gradually maturing. As a future-oriented vehicle platform, it must take into account the hardware foundation for autonomous driving adaptation. Since the vehicle control system of pure electric vehicles is relatively simple and there are not as many control chips as traditional fuel vehicles, pure electric vehicles have natural advantages in being used as L4 autonomous driving models. To this end, Hongqi Motors launched the FME electrified intelligent network technology platform.
First of all, from the technical indicators of this platform, its power battery capacity ranges from 85kWh to 120kWh, and its maximum cruising range can reach 700km. It can be said to be the first echelon of pure electric vehicle cruising range at present. Secondly, this platform is equipped with FEEA2.0 electronic architecture. Compared with the previously commonly used CAN bus communication bus technology, this electronic architecture can carry higher data transmission speed and bandwidth, so that it can handle various driving assistance functions. Even very large data transmission volumes in autonomous driving functions. In addition, as an autonomous vehicle, safety is always the first priority, so vehicle control devices such as braking and steering that are related to the safety of the occupants on the FME platform are equipped with redundant systems.
○The large screen in the media-free holographic interactive car seems to have become the ticket to smart cars. Screens no larger than ten or more inches will subjectively lose several copies. After that, , the quality and innovation of interior design will come more from this. There are some interesting small projects in Hongqi's HIL (Hardware In the Loop, hardware testing in the loop) R&D department, on the Pentium T77 The holographic two-dimensional villain was born in this department. In addition, we have all seen a lot of sci-fi movie scenes where the hands slide the virtual interface in the holographic image in the air to control the overall situation. In the HIL department, there is an exhibition with a similar effect. If What do you think about the fact that you can adjust the air volume of the air conditioner with your hands on an interface suspended in the air? However, the focus of these innovations is to improve the safety and anthropomorphism of human-vehicle interaction.
○? Official picture of the "Cloud" chassis, this hardware is really blocked. Some time ago, we conducted a simple analysis of the new Hongqi factory (Hongqi new factory? Click me). The official picture at that time was just Shows some transformation scenes of the factory. This time, although photos were not allowed on site and we had introduced the general situation of the factory before, what I saw this time was not only the production line of Hongqi H9, but more importantly, we saw Hongqi H9 in the official pictures. Some of its internal structures, especially the chassis, can be made public for the first time. Logically speaking, this is nothing new, but when I turned to the pictures of the Hongqi H9 chassis, I was shocked. On a certain level, I feel that Hongqi has finally "enlightened", created the aura we expect, and bids farewell to the past, which is very "fan-favorite". Of course, a good design alone is not enough to be called high-end. After all, it has already demonstrated its positioning as a "new nobility". If Hongqi wants to gain a foothold, it must show some real skills. There are not many models these days that use front and rear all-aluminum subframes, but since the positioning tone is already very high, it is not surprising to use all-aluminum. According to officials, after using self-designed aluminum profiles to weld the subframe, a 30% weight reduction in the subframe position can be achieved. It can be seen that Hongqi H9 is not only impressive in design, but also in terms of chassis, both materials and structure are at the top level among Chinese brands. It has both lightweight and structural advantages and is very cost-effective.
○? Editor’s comment: From the pictures revealed of the Hongqi H9 chassis, we can be sure that the Hongqi H9 has put a lot of effort into the chassis. Both the materials and structure are of high quality, and the hardware level is at the same price level. Look very powerful. In terms of new energy technology, Hongqi has shown us a grand blueprint: to make full efforts in pure electric, hybrid and fuel cell technologies. From the performance indicators, it is amazing. How is the actual performance? Let us still look forward to these The technology will be installed and implemented as soon as possible. (Text/Picture? Autohome? Wang Miao? Shu Ning? Photography?
