"The platform takes into account both horizontal and vertical configurations, and consists of four core systems: hybrid transmission, hybrid engine, intelligent electric drive and safety battery, and intelligent energy control model, so as to fully build the technological leading edge of Hongqi plug-in hybrid vehicle!" Qiu Xiandong, general manager of FAW Group, introduced the scene.
A number of innovative breakthroughs face the pain points of users. The research and development of HMP, a hybrid platform of Hongqi, lasted for five years, breaking through 526 key core technologies. Focusing on the platform characteristics of safety, low carbon, pleasure and strength, it has many new and original unique technical charms leading the world.
The four core systems of HMP of Hongqi hybrid platform are:
First, an efficient hybrid transmission system. Adhering to the concept of "luxury quality, integrated innovation and extreme exquisiteness" and relying on original configuration, high integration and extreme lean design, Hongqi has built an efficient, powerful and silent hybrid transmission. The comprehensive efficiency is over 90%, and the output torque of longitudinal transmission exceeds 4500Nm；; The output torque of transverse transmission reaches 3900Nm, and the global order noise is lower than 65 dB.
LDU45 is the world's first vertical front-drive dual-motor multi-speed hybrid transmission, which is applied to hybrid vehicles above Class C. It integrates drive axle, transmission, motor and controller, and solves the technical difficulties of traditional vertical transmission in transmitting power forward, achieving the shortest transmission path and the lowest system loss. The multi-gear design keeps the engine speed below 2000 rpm during high-speed cruising, which is in a high-efficiency and low-noise area, effectively solving the problems of high-speed noise and high fuel consumption of most hybrid electric vehicles at present.

In addition, Hongqi has also developed a very compact and efficient transverse hybrid transmission HDU35, which is applied to A-class and B-class hybrid vehicles with the shortest axial length of 376mm in the industry. Medium voltage silicon carbide inverter and multi-layer flat wire oil-cooled motor are used for the first time, which reduces the assembly weight by more than 10kg compared with similar products. At the same time, the newly developed dual-pump hydraulic system has reached the ultimate efficiency of HDU35 products, and the power consumption of the system is reduced by 80% compared with similar products.

Second, the high-performance hybrid engine system. Pursuing high efficiency, comfort and intelligence, Hongqi has built two hybrid engines, 20TD and 15TD, with the thermal efficiency reaching the highest in the industry of 44.3% and 45.2% respectively. The hybrid engine has solved the international problems of "cleaner" and "stronger" at the same time. Under the premise of ensuring high thermal efficiency, it can still achieve ultra-high power above 60kW/L, which is at the international leading level.
Hongqi High Performance Hybrid Engine System
The 20TD hybrid engine adopts many technologies, such as high compression ratio Miller cycle and distributed exhaust gas recirculation, and is equipped with a two-axis balance system, which makes the operation more stable. Aiming at the frequent start-stop working scene, piston self-positioning technology is adopted to reduce vibration and noise 12%, reaching the best level in the same level in the world.
Hongqi 15TD Hybrid Engine
15TD hybrid engine adopts two industry-first technologies of integrated intake and separated exhaust pressurization, which can reduce intake resistance and exhaust interference and make the engine breathe more smoothly. At the same time, it is equipped with a newly developed dynamic lubrication control technology, which reduces the friction loss by 28% and further saves energy consumption. Moreover, Hongqi has reserved the next generation lean-burn engine, and the measured thermal efficiency has exceeded 47%. In the future, it will become an important force to further push the hybrid engine to break through the thermal efficiency barrier at full speed. Third, the power decoupling electric drive system. Let the driver control freely and let the power surge. Hongqi launches power decoupling electric drive system. Under the innovative structure of intelligent disconnection and electric auxiliary drive, the four-wheel drive and two-wheel drive modes can be automatically switched within 100 ms, and there is no resistance loss when the vehicle runs economically, so that the energy consumption of four-wheel drive reaches the level of two-wheel drive, which overcomes the industry difficulty of high no-load energy consumption of new energy four-wheel drive electric drive.
Hongqi Power Decoupling Electric Drive System
Hongqi power decoupling electric drive system can output more than 200kW, and the speed reaches 18000 rpm. The latest generation of high-performance customized magnetic steel and multi-layer square conductor technology are adopted to realize extreme miniaturization and light weight, and the material consumption is reduced by 17% and the weight is less than 74kg；; The breakthrough of global deep frequency conversion and super overmodulation technology makes the vehicle provide better dynamic response and acceleration performance when driving at high speed.
Moreover, the power decoupling electric drive also has excellent mute performance, and the global order noise of silent packaging is less than 65 dB, which is the benchmark level of the international electric drive industry.
Four, high safety and low temperature resistant battery system. Around the full-scene safety and all-weather enjoyment of the battery system, Hongqi has achieved double safety protection and improved low-temperature performance.
Hongqi High Safety Low Temperature Resistant Battery System
Resistant to external damage, the lightweight all-composite box has the strength as high as 1000 MPa and the material characteristics of non-embrittlement, which gives the battery armor-like structural protection when the weight is reduced by more than 15% compared with the metal box; High temperature resistance 1000℃, full insulation, forming three-dimensional electric heating protection, completely eliminating risks such as short circuit and arc. In order to effectively avoid internal anomalies, high-stability battery materials and battery cell structure safety technology are adopted to improve the safety of battery cells; Real-time monitoring and active maintenance of battery health through cloud housekeeper big data drive technology. With the high-safety battery technology, the whole life cycle safety control is implemented to protect users' safety anytime and anywhere!
At the same time, Hongqi has also developed a low-temperature active battery and developed a multi-source intelligent heating technology. Combined with the low thermal conductivity of the fully composite box, it effectively solved the user's pain point of battery performance degradation in the low-temperature environment of electric vehicles. According to the actual measurement on the bench, the available energy is 8% higher than that of the metal box battery when it is placed at minus 20℃ 12 hour, and the power output capacity is more than 25% higher than that of the metal box battery. Really let users travel freely without fear of low temperature.
Hongqi Low Temperature Resistant Battery Technology
On the basis of the four core systems, Hongqi is also committed to developing an exclusive intelligent energy control model to accurately control and fully release the potential of the system, providing users with the ultimate energy-saving and beautiful driving experience.
This algorithm means that by giving the red-flag car self-awareness, it can identify itself and adapt itself, ensuring that all systems have unified thinking and keep pace, and achieving the best results with the least energy consumption; Let the red-flag car clearly understand the external environment, predict the action, and let each system meet the challenge in the best state at any time.
The core of the model is the global energy flow intelligent management algorithm and the intelligent perception energy-saving planning algorithm. The global energy flow intelligent management algorithm, which integrates the transient characteristics of each factor and the user's personalized usage habits, can instantly identify the state of each system and the driver's intention, make the best judgment and issue the best instructions, and meet the dual demands of users for economy and power experience; Intelligent energy-saving planning algorithm, based on cloud big data and road network information, applies machine learning and global optimization to realize the optimal dynamic adjustment of energy without wasting a trace of energy.
Hongqi intelligent energy control model
For example, when there is traffic jam in the city, the algorithm can automatically identify and enter the pure electric drive and series priority mode, and the motor efficiency is always at the best through torque adjustment. After entering the smooth highway, the algorithm can actively identify the driver's driving style, intelligently distribute the electric drive and engine output torque, and accurately control the battery SOC level, so as to prepare for the next road in advance and completely break the inertia logic of using electricity and oil instead of electricity.
Through multi-sample measurement, the intelligent energy management algorithm of Hongqi can reduce the fuel consumption of skilled drivers by more than 8% on average, and realize the intelligent control of machine brain far beyond that of human brain.
Comfortable, stable and safe high-quality travel, based on brand-new and original advanced technology and innovative configuration scheme. The red flag hybrid platform HMP has solved the worries of previous users in a targeted manner, covering more scenes and making the travel experience more comfortable.
In the urban life circle, HMP platform models can bring longer pure electric mileage, reduce vehicle costs with the characteristics of strong economy, fast energy replenishment and low energy replenishment frequency, thus saving energy and labor in commuting and truly realizing "zero" fuel consumption and no burden travel.
In long-distance driving scenarios such as cross-city, outing and self-driving trip, HMP platform models can be called "energy management experts", achieving lower fuel consumption and longer battery life with excellent energy distribution. But also take into account the strong power output to meet the comprehensive needs of various road conditions, so that you can enjoy driving pleasure every time you start. According to reports, according to the plan, Hongqi will gradually introduce hybrid vehicles to the market. Qiu Xiandong said: "In the second half of this year, there will be two vehicle products equipped with HMP platform for mass production. In the future, Hongqi new energy products equipped with HMP platform will continue to meet with you. "
