Changing from oil to electricity is only a partial modification on the basis of existing fuel vehicles, and it has become a new type of hybrid electric vehicle. From the perspective of research and development, it does save time, effort and money, but at the same time, changing from oil to electricity also has considerable limitations, because it is the framework of the fuel vehicle itself, and there are great problems in product performance, body layout, appearance and safety performance.
Limitations of oil-to-electric vehicles;
First, the security is low. In the early gasoline-to-electric vehicles, batteries were usually installed under the car or in the trunk, and the safety problems caused by collision and rear-end collision were particularly prominent. Take the oil-to-electric car as an example, high-voltage lines are placed under the rear seats, and the electromagnetic radiation generated by such cars will pose a great threat to human health;
Second, the space is tight. Because of the limitation of its own structure, fuel vehicles generally occupy the original space in the back row, trunk and chassis. Not to mention the unreasonable layout such as thick threshold and small ground clearance.
Third, battery life is not good. Due to layout problems, the number of batteries in oil-to-electric vehicles will also be limited. In addition, the layout of battery cooling system is usually unreasonable, and the cruising range of vehicles will be greatly limited;
Fourth, poor handling. Because it is difficult to control the front-rear weight ratio, suspension hardness and other details, the braking performance and handling performance of the whole vehicle are usually poor.
Standing on the shoulders of giants, Jetway is obsessed with technology.
Of course, among the car brands, there are also technology streaming players who are unwilling to take shortcuts and stick to their own research and development.
For the development of new energy vehicles in China, as early as 20 15, the Ministry of Science and Technology issued the National Key R&D Plan for New Energy Vehicles (Draft for Comment). Because of the persistence in technology, the exploration of technology and the sense of responsibility of China brand to explore hybrid technology, many manufacturers including Chery Group immediately devoted themselves to the research and development of new energy vehicles. In 20 17, Chery group was successfully selected into the special project of hybrid powertrain development and vehicle integration of new and cost-effective passenger cars of the Ministry of Science and Technology. In view of the fact that the domestic plug-in hybrid power system lags behind the international advanced level in electromechanical coupling device, hybrid engine, hybrid powertrain and other core components, and the economy and ride comfort can not fully meet the market demand, efforts are made to develop a cost-effective electromechanical coupling gearbox to form a mature and reliable passenger car hybrid powertrain.
Thanks to the technology accumulation of Chery Group for 25 years, Jietu Bus Station organically combines the advantages of the platform architecture of the Group with the concept of "Travel on the Giant's Shoulder", actively expands 2DHT and 1DHT on the basis of 3HT, and adds three exclusive hybrid engines, successfully building the Kunlun intelligent hybrid platform specially built for hybrid.
Jietu Automobile adheres to the R&D route, not only because of its enthusiasm for R&D, but also because of the confidence brought by Chery Group's 25-year technical accumulation, the absolute advantage of the group's platform architecture and the correct R&D concept.
After more than three years of clever iteration, Chery Group pursued perfection from more than 65,438+0,000 configurations, and launched the first 3DHT of its own brand, which broke through the technical difficulties of "sticking its neck" in one fell swoop, successfully avoided the patent obstacles of foreign companies in hybrid technology, and opened up a new direction for the research of brand hybrid technology in China.
The first product of Kunlun intelligent Mix platform-Jietu Sheng Da i-DM native intelligent Mix
As the first product of this platform, Jietu Sheng Da i-DM Native Intelligent Hybrid is undoubtedly the pioneer of China Native Intelligent Hybrid SUV, which comes from Kunlun Intelligent Hybrid Platform and has obvious advantages in system, structure, product performance and vehicle layout.
Jietu Sheng Da i-DM put the pain points of hybrid vehicles into a unified framework from the beginning of design, and solved many problems such as tight space, weak performance, poor endurance and insufficient safety of oil-to-electric vehicles. Thanks to the chassis specially designed for hybrid electric vehicles, the layout of the three electric systems is fully considered. Both the battery and the fuel tank are arranged in the middle of the car body, which also has the advantages of low center of gravity and stable driving control.
The traditional distributed electronic architecture is usually used for fuel-fired vehicles or vehicles that convert from fuel to electricity. Each electronic control unit is usually only responsible for one functional unit, which is independent of each other. The engine, brakes, doors and other components are all in their own way, which can not achieve unified command and dispatch, resulting in a serious waste of computing power. Coupled with different hardware, different embedded software and underlying code, the increase of new functional components in new car configuration will make its architecture more chaotic and overwhelmed.
The unbounded electronic architecture adopted by Jietu Sheng Da i-DM adopts advanced designs such as integrated gateway design, special P-CAN for new energy and experiential electronic architecture. As the interactive hub of vehicle networking data, it has the characteristics of strong computing power, multi-channel, fast response and safer, and can better adapt to the advanced electronic equipment of new energy vehicles.
Compared with the traditional mechanical chassis, it consists of four parts: transmission system, running system, steering system and braking system, and is driven by mechanical signals. The integrated WCBS drive-by-wire chassis adopted by Jetway Sheng Da i-DM is electrically controlled and more responsive. Using electrical signal transmission instead of mechanical signal transmission has the advantages of high precision, high safety and fast response, which is also the advantage of its L2 intelligent assisted driving.
Write at the end:
The strength of Jetway, who takes the technical route, is self-evident, but the original intelligence of Jetway i-DM is not a technical man who can only wear a plaid shirt and can't dress up without luxury. It also has a cool futuristic appearance and a minimalist technology interior.
Borderless air intake grille with full LED light group and intelligent stealth sensor handle, 20-inch cutting wheel hub, mecha spoiler and other design elements are all popular design elements for young users nowadays. Comparable to the interior of Tesla minimalist technology, the 15.6-inch floating smart large screen is full of futuristic technology, with integrated flight seats, intelligent voice interactive AI lights, Mercedes-Benz luxury electronic arms, colorful rhythmic atmosphere lights, and wireless fast charging of 40W mobile phones. Jietu Sheng Da i-DM can not only dress up, but also know what is quality, luxury and car enjoyment!
