Evolutional Research On Domestic Automobile Electronic Technology Based On The Analysis Of Patent

In recent years, China's auto industry has become a pillar industry of the national economy due to its high-speed development. The blossom of automobile industry provides a broad market space for the progress of auto electronic industry, and its industrialization will be a new growth point of economic development and will bring a huge economic benefits. However, those high technical and lucrative products in the upstream chain are monopolized by foreign enterprises, in contrast, domestic enterprises yields low-end products of low technology and thin profits.Currently, enterprises should devote themselves to independent innovation, absorbing overseas cutting-edge technology and boost automobile, IT and other industries to form a strategic cooperation as to realize independent application of auto electronic technology and the improvement of electronic products R & D capabilities. It will strengthen the ability to provide the auxiliary items of auto industry and hi-tech exploitation, which accelerates transformation of domestic auto industry and establishes a solid foundation for internationally competitive auto industry. It researches evolution of automobile electronic technology system under this background, which will provide feasible references for the research orientations and routes of enterprises.This dissertation was conducted mainly on the object of the development of domestic automobile electronic technology, exerts a quantitative and qualitative analysis on patents of automobile electronic technology, draws relevant patent maps, through which finds out the current status and developing trend of domestic automobile electronic technology. It further applies theory of technology evolution within TRIZ to analyze patent maps in order to locate the evolution models and corresponding evolution routes for domestic automobile electronic technology.Chapter 1 is the introduction, which illustrates the background and motivation of topic selection, analyzes theoretical and realistic significance of the topic and introduces the research idea and methods briefly; literature review forms chapter 2. Firstly, it introduces values and characteristics of patents, and then derives feasibility and worth of this research. Subsequently, it further discusses and prefects the methods of researching patents and patent mapping. Lastly, it introduces theories of TRIZ and its evolution, finds out the model of technology system evolution and feasibility of the technology route. In chapter 3, it discusses and maturates the methods and tactics of collecting patent information, then contrives patent management maps based on the collected information. It contains elaborative interpretation of patent information obtained and draws patent technology map in chapter 4. This paper analyzes the patent applied with TRIZ theory in-depth and finds out the evolution model and route token automobile sensors as an empirical study. Chapter 6 wraps up this dissertation, summarizing the research content and achievements and pointing out the deficiencies within the study and research perspectives for next stage.
