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 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 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 A In the last decade， the users of motor vehicles for the comfort， safety and environmental requirements such as performance 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 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 To address these problems， many new models (especially the high-end models) the beginning of the development of the wider use of computer network 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 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 One is car-car electronic devices， including motor vehicle information systems， navigation systems， car audio and video entertainment systems， automotive communications systems， Internet
随着我国经济的发展和人民生活水平的提高，作为最主要的交通工具——汽车也逐渐走进了普通百姓的家庭生活，交通的状况和环境也不断的得到发展，而随之而来的是越来越严重的交通事故的不断发生。 With the development of our national economy and the improvement of people's living standard， as the main transportation - car also gradually entered the ordinary people of family life， the traffic situation and environment also constantly developed， and the consequent is more and more serious traffic accident occur 目前中国是已成为世界上因交通死亡人数最多的国家，而且是交通事故死亡率最高的国家。 China is now the world has become because of traffic deaths most populous country， and is traffic accident rates are highest 如何降低交通事故率已成为了一个刻不容缓的问题。 How to reduce traffic accidents has become an urgent 但在我国许多交通事故都在呈下降趋势的同时，因冬季天气有关而导致的交通事故却在大量的增加。 But many of the traffic accidents in China in the meanwhile， declined by about winter weather caused traffic accident but in a lot of 经研究表明，影响冬季环境下道路交通安全的因素主要有人的因素、路况因素、车辆因素、自然环境因素和管理因素五个方面。 The study showed that winter environment influence factors of road traffic safety factors of main someone， the road factors， vehicle factors， natural environment factors and management factors 5 本文通过阐明冬季环境下冰雪路面及其他因素对交通安全带来的危害，分析我国交通事故的发展和现状规模，提出在冬季环境下交通事故的发生远远高于别的季节，从而研究影响冬季环境下道路交通安全的因素的详细情况，并进一步提出加强冬季环境下道路交通安全的技术措施，以减小冬季环境对道路交通安全的危害。 This paper elucidate winter environment and he factors on ice road traffic safety， analyzes the harm of traffic accidents， and puts forward the development and current situation in winter scale under the environment of traffic accidents far higher than other seasons， so the impact winter environment factors of road traffic safety， and further details of proposed that strengthening the winter environment road traffic safety technical measures to reduce the winter environment of road traffic safety
The automobile electronic control system by the sensor， the electronic control module， the actuator three major part is composed， divides into the engine electrically controlled technology， the chassis electrically controlled technology， the automobile body safe electrically controlled technology approximately by its development's new The electrically controlled system has made the important contribution in modern automobile various aspects various This article take the chassis electrically controlled technology's in security aerocyst technology as an example， has conducted the research to the auto safety domain in take the electrically controlled technology as the core safety The security aerocyst takes in the automobile passive safety device an important item of equipment， has protected personnel riding on the vehicle's safety Indicated through the massive statistics and the actual material， when the automobile bumps into， can use the safety belt and the security aerocyst correctly may cause the head injury rate reduction 30%-50%， face being injured rate reduction 70%-80% This article through has the safekeeping of security to the security aerocyst movement the time process and related actual carries on the sketchy research analysis to verify the security aerocyst the
