Guide the future development of the concept of automotive vehicles Summary of high-tech popularization and application makes the pace of replacement automotive products faster and faster, also makes the Chinese automotive industry independent research and development level and technical level with the international on the growing gap in the development of the concept car is even more the difference between the very WTO accession for China car alarm sounded, but also tremendous opportunity, our government, as well as automotive companies must increase their research and automotive design input, to establish a positive right car design concept, the concept of extensive vehicle design Keywords concept car designed to develop science, technology and culture Technology start-ups PIONEERINGWITHSCIENCE & TECHNOLOGYMONTHLY The 21st century, in order to lead and performance of the new century, the development of future automotive trends, a number of international auto companies, one after another at the major auto show in the world to launch its own concept car and new There is, however, must be caused by a phenomenon we are concerned about: As a car big country, but few Chinese car makers to launch its own development and design concept Are one of the main reasons for China's automotive design concepts and methods, as well as the lack of research and development of concept cars do not pay enough It can be said that a self-designed and self-development capacity of the automobile industry, it is difficult to say that is a complete auto Thus we must intensify the study of automotive design and input, to establish a positive right car design concept, the concept of extensive vehicle 1 "concept car" is defined The so-called "concept cars" that have not yet begun to enter the market with a design unique and must advance the awareness of the new Its main characteristics are: it must give people are to consider that can guide the new concept It has just the design in general at the time, people's aesthetic ideas, the purchasing power and even the level of motor vehicle manufacturing industry is also Generally it will be it avant-garde design, innovative materials, bold use of a more perfect performance, the new car interior design indicates that the direction of development of the automobile Some of the world's largest car company every year to spend many human and material resources to design their own concept car, and in some large auto exposition on It can be said that with the continuous introduction of concept cars, the near future may occur on some concept cars have today, some features or functions of the But not necessarily a concept car will each eventually evolve into mass production cars to enter the market, the majority of concept cars are finally only a "concept" for people to discuss the 2 concept car, in reality the meaning of 1 concept car design and development of automotive products reflected the development trend of 1
