正随着汽车变得越来越"聪明",人们可以用这种交通工具来做越来越多的事情。未来的汽车已不仅仅是一个代步工具,而是一个能提供多种出行服务的移动空间。过去收音机几乎是汽车上唯一的娱乐功能,现如今听歌、导航、语音交互等功能已成为很多人心目中汽车上理所当然的标配。以前驾驶者是车辆唯一的控制者,如今驾驶辅助系统和主动安全系统的加入让人们越来越享受这种更安全轻松的出行体验。随着时间的推移,人们对汽车的期待会比现在更多。"开放"和"互联"是未来出行解决方案的关键词,如果汽车始终作为 相似文献

功不可没的铅酸电池已有百多年的历史了,它对人类的文明史的贡献是不容低估的。当前,人们出行的主导代步工具——汽车、飞机、轮船、摩托车及近年发展起来的电动自行车、电动代步车、残疾人轮椅和各种电动休闲车等都在大量应用着铅酸电池。正因为如此,全国各地遍布着3000多家电池生产厂,铅酸电池也是当前技术最成熟、价格最低廉的电池,但它存在着能量密度和功率密度低下以及硫酸和重金属铅污染环境的问题。因此,人们也从未间断过对其进行改革和开发新电池的工作。 相似文献

The most vulnerable user in road space is still an ordinary pedestrian even though the top fatalities by traffic mode differ in countries. Thus, prioritizing/protecting vulnerable road users is essential to improve road safety. People's safety perceptions toward vulnerable users are strongly associated with surrounding elements and their own experiences, especially as pedestrians. Therefore the attitude and values toward vulnerable users would vary due to culture and customs related to walking in each country. This study examines how a walking experience change reflects people with diverse backgrounds' traffic safety attitudes by conducting an online questionnaire survey for foreigners living in Japan for five years or less. As a result, 75% of respondents walk more frequently due to increased public transportation usage. For all the respondents, the increase in the walking frequency also drives the shift in the attitude toward vulnerable users and the values regarding travel safety and comfort indirectly intermediated by the shift in attitudes toward walkability, applying structural equation modeling. To focus on the structure of the shift according to nationality, people from Southeast/South Asia, where motorcyclists are the top fatalities in the road space and somehow regarded as vulnerable road users, the increased walking experience contributes significantly to the improvement of awareness of vulnerable road users and to the formation of safety and comfort values. Regarding people from Europe/North America, although their walking frequency increases after coming to Japan, there is a static causal relationship that does not influence their attitude toward walkability or safety and comfort values. Additionally, they already have an attitude of protecting/prioritizing pedestrians and placing more importance on safety and comfort. At the same time, people from Southeast/South lacks the attitude toward pedestrians due to much less frequency of walking in daily life. It suggests that establishing safe and having comfortable pedestrian spaces and public transport in developing countries where traffic infrastructure is at the development stage will encourage people to walk and likely help foster an attitude of placing importance on safety. 相似文献

随着经济与科技的不断发展,目前我国人民生活水平已经普遍得到了提升。在此背景下,人们对出行的需求也在不断攀升,汽车的出现和发展无疑受到了人们的接受与欢迎,并成为了当今社会人们出行的主要交通工具。但是汽车内部的组成结构十分复杂,这其中发动机作为动力部件,则更为复杂。现如今汽车发动机基本上都采用了电子控制系统进行控制,其质量高低将决定汽车的性能和寿命。在驾驶员驾驶车辆的过程中,汽车发动机难免会遇到故障,尤其是电控发动机点火系统一旦出现问题,汽车则可能无法正常行驶。本文从汽车电控发动机技术的概念、汽车电控发动机点火系统的常见故障与原因分析以及汽车电控发动机点火系统故障的诊断和维修这几个方面展开探讨,并对汽车电控发动机点火系统故障的诊断及排除提出了个人的见解。 相似文献

Vehicle overloading has been identified as one of the major contributors to road pavement damage in Malaysia. In this study, the weigh-in-motion (WIM) system has been used to function as a vehicle weight sorting tool to complement the exsiting static weigh bridge enforcement station. Data collected from the developed system is used to explore the effectiveness of using WIM system in terms of generating more accurate data for enforcement purposes and at the same time improving safety and reducing the number of vehicle weight violations on the roads. This study specifically focus on the effect of vehicle by-pass and static weigh station enforcement capability on the overall effectiveness of vehicle weight enforcement system in a developing country. Results from this study suggest that the WIM system will significantly enhance the effectiveness and efficiency of the current vehicle weight enforcement, thus generating substantial revenue that would greatly off-set the current road maintenance budget that comes from tax payers money. If there is substantial reduction in overloaded vehicles, the public will still gain through reduction in road maintenance budget, less accident risks involving heavy trucks, and lesser greenhouse gases (GHGs) emissions. 相似文献

The perspectives of research for enhancing active safety based on advanced control technology 总被引:1,自引:0,他引:1
《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》2007,45(5):413-431
This paper considers the scope and the methodologies for enhancing active safety of road vehicles by sensing and control technologies. The first part of this paper introduces statistical data of traffic accidents in Japan, and describes the development of the drive recorder for accident/incident survey and analysis. Based on vehicle dynamics data, the algorithm of the drive recorder for capturing near-miss incident data is introduced. The second part of this paper reviews control problems of vehicle dynamics on micro-scale electric vehicles for enhancing vehicle dynamics and driving assistance function. In particular, the direct yaw moment control using in-wheel-motors and the active front steering control algorithm are described. The third part of the paper introduces the advanced driver assistance system adapted to driver characteristics and traffic situations. This part mainly describes an adaptive system, which adjusts the assisting manoeuvre depending on individual driver behaviour and situation, and some experimental investigations using the active interface vehicle and driving simulator. Finally, some perspectives and new challenges for future research on vehicle control technology are mentioned. 相似文献
