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 poor. 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 car. 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 cars. 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 attention. 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 industry. Thus we must intensify the study of automotive design and input, to establish a positive right car design concept, the concept of extensive vehicle design. 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 models. Its main characteristics are: it must give people are to consider that can guide the new concept cars. 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 unbearable. 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 industry. 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 display. 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 car. 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 matter. 2 concept car, in reality the meaning of 2.1 concept car design and development of automotive products reflected the development trend of 2.1.1 the performance of the highest scientific level and the most sophisticated technology in concept car At the International Motor Show the previous, and the major automotive companies and the introduction of the concept of lot of cars, concept cars to remove these sleek, but also more integrated into a large number of high-tech and modern means of the introduction of the concept car to become Motor Company takes pride in the idea of the concept of automotive research and development are often accompanied by new technologies and the use of new materials with certain forward-looking, herald a new stage of development and the beginning for this reason that car companies the development of the concept car has invested great human and material resources, with its show car the company's strong momentum of development. Various high-tech applications, making car slowly evolved into information, communications, entertainment centers and the exchange of information with the outside world, the computer functions and Internet all-round involvement, in-car information and entertainment equipment, advanced navigation equipment, real-time traffic information function of the growing popularity of the inevitable demand of these high-tech automotive designers transcend time and space to establish a new value system, the emergence of various new technologies for the automotive design freely given to a wider space. Function of motor vehicles for further expansion and development of the concept car, the car gradually from the cold machinery into human information exchange platform, if the concept car has its own way of expressing their emotions with pregnant, anger, sadness and joy, such as facial expression make the concept car than in high volume production cars, become a new symbol of time. Concept Car Design of automotive products have greater and greater impact, it represents the development direction of the automobile industry and the basic idea of the automobile company design standards and a symbol of scientific and technological level. 2.1.2 human physiological needs and psychological needs of the largest Satisfied --- Automotive Engineering in the Ergonomics Ergonomics are 50 in the early 20th century with the rapid development of a new subject with the aim of research, design and engineering technology to solve the relationship between the human body. Car body design in ergonomics, it is to people (drivers and passengers) as the center, from the body's physiology, psychology, and exercise the human body, the research body design, layout and equipment in terms of how to adapt to people need to create a manipulation convenient, safe, reliable, beautiful and comfortable driving environment and take the environment, that is the best person to design a - vehicle - environment system. Automotive Design Human-Computer analysis of the first ministries to human size required for measurement, statistics and analysis, conducting interior layout design as a basis to determine the effective space vehicle, as well as parts, assemblies (seats, dashboard , steering wheel, etc.) position and dimensions of the relationship between layout. Through the study of human physiological structure, so that the seat design in full compliance with the requirements of human comfort. Based on the manipulation of human manipulation of the scope and power to determine the layout of the manipulator position and force size, so that when the human body to manipulate natural, rapid, accurate and lightweight, so as to reduce the degree of manipulation of fatigue. Through the visual characteristics of the human eye, the effect of vision research, testing, checking driver information system, to ensure that drivers have access to proper driving information. Exercise in accordance with the characteristics of the human body to study the automobile collision on the human body, a reasonable protection, the right to determine the hinged point seat belts and binding on the human body to study the vibration of the impact on ride comfort, research on and get off at the convenience of passengers, and door openings in order to determine location and size. According to the body's physiological requirements, reasonable certainty that the air-conditioning system and layout. Research on the psychological characteristics and requirements, to design a comfortable, beautiful, relaxed by the environment. 2.1.3 virtual product development technology At present, a growing number of automotive design companies and manufacturing companies to start using virtual product development technology, using three-dimensional virtual reality 3D technology development concept car. Opel car using 3D virtual reality technology concept car design and development. Designers can experience floating in the air of a virtual image of car design and manufacturing, saving considerable development costs, and plans to be extended to its North American assembly plant to 14. Britain's Rolls-Royce, Renault, France, Germany Audi, as well as Italy, Sweden and other auto plants are actively engaged in this virtual design and manufacturing. Over the past automotive research and development centers to develop new or modified are first shaped body sludge physical model, is extremely time-consuming modifications. Now automotive R & D, in particular the development of concept cars are increasingly seeking the shortest development time. If the introduction of virtual product development technologies, as long as the computer input data to construct a model figure model, in the laboratory can show an ideal vehicle images, as long as the engineers wear eyepiece, you can see clearly, there is such as a car in front of us true, after all the discussion of design engineers modifications, you can quickly design an ideal new car. Stereotypes, the computer can use the data, outsourcing trial and trial fitted the new parts and components, assembly achieve zero error, and the development of aging more rapidly than in the past. 2.1.4 the concept of green environment-friendly vehicles to the development trend of Since entering the 21st century, countries around the world have been produced about 1.5 billion vehicles, according to expert estimates that in 2010 global vehicle production will reach 75 million. People sigh at the rapid development of automobile industry, but also an increasing awareness of pollution from motor vehicles to harm human beings, so many countries of the vehicle to develop environmental protection measures and regulations to protect the environment for human survival, so automotive environmental protection the design of this new concept car design to be placed in a prominent position on the essential. Improve energy efficiency, improved engine configurations, including electronically controlled fuel injection system, secondary air injection, thermal reactor, exhaust gas recirculation system, catalytic purification device, crankcase ventilation systems, fuel evaporation control system. The development of alternative fuels, research and development of new environmentally-friendly energy, including natural gas, liquefied petroleum gas, fast charging batteries, hybrid power, hydrogen fuel. In the automotive manufacturing process, use of green materials, green packaging, green manufacturing processes and equipment and equipment green. Green car recycling manufacturers. 2.2 Concept car indicates road traffic in the evolution of human behavior 2.2.1 Concept foretells the future of the way road traffic trends Along with the development of automobile, the vehicle status is also slowly change, now car in people's minds as a symbol, a symbol of wealth and the embodiment of a status, but the car as a way of the nature of road traffic has overlooked. Concept car design is based on the nature of a car's innovative design predictability. Concept car at the design of the way through the daily life of mankind, human beings in road traffic in the use of methods such as behavior and ways of life all aspects of prediction and analysis, it is envisaged to solve the future in the way road traffic between the object harmonious factors. Strong and high-speed in today's technology enables the development of means of transport have a much broader space for development, more and more high-tech continuously applied at a new car. At present many of the world's major auto companies have realized that the development of the next car is no longer the biggest obstacles are technical limitations, but limits the designers thinking. Now appearing in major auto show concept cars are generally two types: one is based on the latest available technology can achieve another kind of concept cars are those who put forward some innovative technology options but is still in the research phase of the concept car. Able to express their feelings such as car, truck can random shell replacement car, be able to easily change the driving mode of motor vehicles, be able to swim in the water of the amphibious vehicle, able to fly in space vehicles, be able to change cars. Like from Toyota and Sony jointly developed by "POD" cars, will be able to through the car before the lights, mirrors, antenna, as well as the rear seat to the car owners to express their "feelings." Like Volkswagen's Seat International Auto Show in the United States on the introduction of multi-functional concept car "Sal? Juancheng sa", there are sports, comfort and three kinds of urban-type driving mode selection for you. 2.2.2 Concept of culture differences in performance The United States as a world leader in the auto industry, concept cars at the manufacturing are on the forefront in the world. At the United States because of cultural blending, collision, so the concept car embodies the greater the diversity of cultures; are also caused by a highly developed country commercial, commercial design and pragmatism prevailed, so the design is set up at a deep aesthetic Ethics on the real and solve practical problems. With the American cars are in sharp contrast to the Japanese concept cars. Japan as the world's output of the second car big country, its concept car many practical and imagination, technology is better than art, more concerned about solving technical problems, it can be said in Japan This is the premise of the concept of car design, each model is to solve one kinds of technical problems developed. The Japanese car model to maintain a small, simple, style characteristics of the economy and harmonious relations between man-machine deal with the Japanese are reflected as a delicate oriental thinking and compromise approach to solve the problem. The United States put the design of commercial operation as an important aspect, Japan put out of Products Designed to accelerate as a tool, Germany put Designed as a social and cultural foundation, while the French took the design as a designer of stage performance. From various countries so the concept of car design in different styles, we can see different countries, different concepts, as well as their different cultural backgrounds design. 3 Concluding remarks The future of automotive design as the development of the inevitable progress of Automotive Technology with each passing day, many of the artistic style of the designer will make it even more widely and more strongly reflected in the car design, and give people a wider choice. Under high-tech, and personality of the car more humane 21st century will be the necessity of the development of the automobile industry, because it is consistent with human culture, the pursuit of individuality and needs. Therefore, the increase in automobile design concept of the attention and input, will be the development of China's automobile industry has played a great role in pushing forward. References 1尹定邦.
