感谢邀请回答问题，中国汽车销售不好是有原因的，大家表面看见什么长城啊宝骏销，售排在前十榜其实面好看，国产汽车主打低端市场，主要是以薄利多销为原则，国产卖5到10辆车才相当于合资车的利润，豪华车利润都不说了，比如吉利宝骏这些基本一辆车才几千块钱的利润，自主汽车目前无法站在汽车市场高端，也不会被看好是因为没有核心技术，靠摸着人家路子过河，不断模仿改进融合，国产现在连外观设计都请国外设计师操刀了，就不要想国产汽车未来了，没有一款全球公认的发动机心脏，没有可靠的三大件，没有品牌形象，就没有竞争力。

我国自主汽车发展现状和趋势分析的论文中英文摘要

abstract
society into the information network era, the requirements of the vehicle no longer be satisfied with a means of transport, but also want to live and work car is an extension of the scope, in the car like in their own office and home work and life. at the same time, the growing automotive electronics and also the rapid development of automotive technology was considered in the development process of a revolution of automotive electronics is a measure of the degree is seen as an important level of hyundai motor signs. with computer technology, communication technology, the rapid development of integrated circuit technology in order to figure represented fieldbus field instrument, equipment, a large number of applications, red tape has been the scene of a single simple connection of fieldbus networks in place of, the quality of signal transmission also greatly improved, cars have begun to enter the internet age.
in the last decade, the users of motor vehicles for the comfort, safety and environmental requirements such as performance improved. in order to meet these ever-increasing demand for computer-controlled vehicle electrical and electronic equipment increased dramatically, making vehicles (especially cars) the design of the layout of electrical circuits has become increasingly difficult. in addition, a variety of automotive electrical and electronic connector of the ensuing surge in the number of motor vehicles traveling on the course because of the failure point connector automotive electrical and electronic equipment on the issue of failure to perform its functions more and more prominent. to address these problems, many new models (especially the high-end models) the beginning of the development of the wider use of computer network technology. in this paper, computer network technology in the automotive application of the basic principles of network technology on the inside and outside the vehicle, the introduction of the internal network, introduced the characteristics of automotive and automotive standards for the internal network, focuses on the control of the main local area network can characteristics and their applications.
vehicle performance in accordance with the role of the impact of division of motor vehicle electronic products can be summarized as two types: one is the automotive electronic control devices, including the engine, chassis and body electronic control. one is car-car electronic devices, including motor vehicle information systems, navigation systems, car audio and video entertainment systems, automotive communications systems, internet equipment.
