Solution details
- Field of science and technology: It belongs to innovation in the field of cost breakthroughs and system development technology. Relying on the local platform of SGM615(New Excelle), a lean air conditioning system based on market demand and cost advantages has been independently developed throughout the process, and has been widely used in actual mass production vehicles.
- Main research contents and results achieved: 2-1 Innovatively apply the human comfort model and combine it with the actual needs of customers in the market in the collected place to accurately decompose and select various components of the vehicle's air conditioning system to provide a comfortable driving environment in the car. 2-2 Using a compressor with low torque requirements reduces the power demand and load of the compressor on the engine, effectively reducing energy consumption compared to other air conditioning systems. 2-3 Adopt the platform-based design concept and carry out platform-based development, so that this air conditioning system can be transplanted to a platform covering low, medium and high-end models only by changing the peripheral design of air conditioning pipes, air conditioning box shells and other peripheral designs. Improve the reusability of development results, greatly improve the reliability of air conditioning systems, and reduce development costs and the cost of single vehicle parts. 2-4 Independent development throughout the process: Guided by market research, accurately set target values for the whole vehicle, reasonably decompose and formulate CTS based on CAE virtual means, independently release SOR and designate suppliers, prepare for vehicle building at corresponding nodes based on bench development experiments, lead environmental simulation wind tunnel system integration and development tests, as well as all-weather road development tests in summer and winter.
- Technical characteristics and promotion status. Low cost & high quality: The entire air conditioning system adopts a platform-based design concept, so that it can be transplanted to platforms covering low, medium and high-end models simply by changing the peripheral design of air conditioning pipes, air conditioning box shells, etc., and the development and verification tests of core components. The number of times is greatly reduced. Improving the reusability of development results also greatly improves the reliability of the air conditioning system, while reducing the development cycle, cost and cost of single vehicle parts. At the same time, the use of low-IPTV compressors greatly reduces the after-sales costs of this model, which is also conducive to the construction of BUICK brand reputation. High cooling and heating performance: Through bench performance development experiments, environmental simulation wind tunnel system integration and development tests, and all-weather road development tests in summer and winter, the results show that the performance of the currently developed low-cost air conditioning system is better than that of the previous generation, as well as the market. Competitive cars of the same level. Low energy consumption: The compressor used in the new air conditioning system of the local project developed is a compressor with low torque demand, which reduces the power demand and load of the compressor on the engine, and can reduce energy consumption more effectively compared to other air conditioning systems. The development of lean air conditioning systems based on market demand and cost advantages is the first summary, improvement and lean practice of the entire process and independent development of local project air conditioning systems. It is a comprehensive and correct understanding of the global platform air conditioning system development process, and an innovative establishment based on market demand and a working system for the development of lean air conditioning systems with cost advantages. It is of great reference significance for the company to develop other future projects based on market demand and cost-advantageous lean air conditioning systems.
- Papers and patents, domestic and foreign evaluation, citation or promotion and application, and economic and social benefits. Talent training, promotion of discipline development, industry scientific and technological progress, etc.: Relying on the new air conditioning system development platform for local projects, the air conditioning team focuses on accumulation. During the project, the team published 4 papers and applied for 7 patents, including 1 invention patent authorized by SIPO, 1 paper published in core journals of automobiles, and 1 paper published in core journals of the machinery and instrument industry. The development experience of the new air conditioning system of this local project SGM 615 (New Excelle) has been deeply integrated into Pan-Asia's air conditioning development process, and has been fully applied to the development of subsequent local projects such as SGM K211 (New Yinglang) air conditioning system and has also been successfully launched. Excellent air conditioning performance. During the project development process, an innovation team in the field of cost breakthroughs and system development technology led by technical experts in this field has gradually formed. The team will play an important role in the development of more local projects in the future. After more than 2 years of application, more than 220 million yuan has been saved.
