  • 51961.基于模型的运输绩效:比较框架和文献合成

    [汽车制造业,信息传输、软件和信息技术服务业] [2014-07-24]

    In an era of limited resources and a proliferation of data, there is increasing pressure to conduct careful evaluations of the economic, environmental, and equity effects of investments and policies that influence transportation and land-use systems. This report compares performance measures recommended to achieve desired goals and reviews the literature to determine the degree to which these measures have been implemented and what they indicate about the relative effectiveness of land-use, transit, and automobile pricing policies. Despite the variation in methods and performance measures implemented in the studies reviewed for this report, the synthesis of study results suggests the direction and relative magnitude of change resulting from different types of policies, as well as potential biases introduced by omitting the representation of the land-use and transportation interaction. Overall, the performance measures indicate that carefully designed transit, land-use, and automobile pricing policies may improve travel, economic, environmental, and equity conditions for communities. However, transit and peak-period automobile pricing policies can, in some situations, lead to negative performance outcomes across some or all measures, as illustrated in studies that explicitly represent the land-use and transportation interaction.

  • 51962.在汽车火灾中提高生存能力

    [汽车制造业] [2014-07-24]

    Automobile fires are consistently among the largest causes of fire death in the United States (about 500 annually) and the U.S. motor vehicle industry has spent $14 million in recent years studying this problem. The authors of this review have analyzed the auto industry reports, the scientific literature, and statistical data, and conclude that measures should be taken to improve survivability in automobile fires. The US Federal Motor Vehicle Safety Standard 302 was introduced almost 40 years ago to measure the flammability of interior materials, but improvements in the crashworthiness of automobiles and their fuel tanks and the increased use of combustible materials has changed the motor vehicle fire scenario significantly. In particular, the primary threat has changed from ignition of a small quantity of combustible interior materials by a lit cigarette, in 1960, to ignition of a large quantity of combustible interior and exterior materials by an impact-induced fire, at present. The authors therefore suggest that FMVSS 302 is no longer relevant to automobile fire safety and recommend improved standards based on objective criteria for fire safety performance (fireworthiness) at the system/vehicle level as is routinely done for crashworthiness.

  • 51963.使用车辆的实时信息为汽车保险服务的研究

    [汽车制造业] [2014-07-24]

    Recently the convergence of IT Services is using much information. Fusion of vehicle information technology and IT services are developing very fast. In this paper is about car insurance service used vehicle information and user information. In this paper, the car insurance service is convergence that vehicle information and user information. We propose accident service, eco-driving service, breakdown service based on the information collected from the vehicle.

  • 51964.计算机视觉应用到车辆中的极端测试

    [汽车制造业] [2014-07-24]

    VisLab has been pioneering the world of autonomous driving since its early years; in 1998 VisLab organized one of the most innovative experiments for that period: a passenger car was equipped with sensing and actuation devices and was tested with autonomous steering along a 2000+ km on Italian highways

  • 51965.基于同步制造的决策支持仿真系统

    [信息传输、软件和信息技术服务业,汽车制造业] [2014-07-24]

    The focus of the article was the redesign of an assembly cell in a car manufacturing company. The new design had to include the operations related to the assembly of new roofs without disrupting the throughput rate. The theory-of-constrains framework has been used to propose designs as well as to define the evaluation criteria. The complexity of the system has been studied using a discrete-event simulation model. The traditional scholar steps have been followed to develop a robust decision support simulation system (DSSS).

  • 51966.将主动悬置发动机振动隔离应用到模糊控制

    [汽车制造业] [2014-07-24]

    An automobile power-train active mount system with a piezoelectric stack actuator is introduced.The influence caused by power-train to the body of the car is analyzed by means of parameter self-tuning fuzzy PID control,on which the simulating results are based.It turns out that this control scheme can restrain the influence better caused by power-train to the body of the car.

  • 51970.汽车动力锂电池的资源化利用技术探讨

    [汽车制造业] [2014-07-22]

    能源枯竭、环境污染已经成为当今社会不得不面对并急需解决的问题,新能源汽车也不断地在更多的国家被研发推广。我国在《节能与新能源汽车产业发展规划(2012-2020年)》中,也对新能源汽车发展规划做了新的诠释。作为新能源汽车产业链中的重要组成部分,动力电池,尤其是以磷酸铁锂作为正极材料的锂离子电池得到了广泛的应用,锂离子电池的数量也将出现爆发式增长。虽然锂离子电池被称为“绿色电池”,不像传统的铅酸蓄电池、镍镉电池那样含有汞、镉、铅等毒害大、污染严重的重金属元素,真正实现了零排放、零污染,但是其正负极材料、电解质溶液等物质对环境还是有很大的影响。目前我国车用动力电池研究主要集中在提高其安全性能及使用寿命等方面,在回收利用环节却严重脱节,因此,动力电池如何回收与再利用技术的探索已成为一个不可忽视的问题。废旧锂离子电池的回收利用,不仅能够减轻对环境的影响,同时还能带来一定的经济效益,是国家新能源汽车产业发展的重要环节之一。
