52461.电磁干扰效应对汽车电子控制和安全装置。第二卷。测量,分析和测试。
[汽车制造业] [2013-12-22]
The report contains the results of a test series to evaluate the electrical environment of a motor vehicle during normal operating conditions and a summary of power supply variations and electrical signal transient characteristics. Both source and coupled signals were measured. A computerized coupling analysis program was used to determine the effects of body shielding,aperture size,and cable lengths on signal coupling in the 100to 200MHz band between a simulated mobile radio emission and a modeled air-cushion restraint system cable as it might be used in a motor vehicle. A series of susceptibility tests were performed on an electronic speed control system and an anti-skid control module to determine functional upset levels of injected signals at critical circuit ports on these devices. The upset criteria were based on performance departures from normal,resulting from the injection of interfering signals. The injected signals were designed to represent levels and durations characteristic of those generated within the vehicle or coupled from external sources.

52463.车轮力传感器的研究和开发
[汽车制造业] [2013-12-22]
This document forms the third progress report on the development of a concept wheel force transducer that can measure the forces and moments between a tire and a road on a HMMWV driven under off-road conditions. This concept development is part of a project that endeavors to develop, validate and calibrate cost effective field test equipment for measuring tire characteristics on vehicles whilst driving off-road. The proposed wheel force transducer is an important step in a renewed research effort that aims to correct the gap in current tire testing and modeling knowledge to ensure that future off-road vehicle models and simulation efforts are conducted with confidence. The report briefly describes the fatigue testing performed on material samples as well as manufacturing and progress with fatigue testing of the first prototype.

52464.基于代理的信息系统为电动汽车充电基础设施部署
[汽车制造业] [2013-12-22]
The current scarcity of public charging infrastructure is one of the major barriers to mass household adoption of plug-in electric vehicles (PEVs). Although most PEV drivers can recharge their vehicles at home, the limited driving range of the vehicles restricts their usefulness for long-distance travel. In this paper, an agent-based information system is presented for identifying patterns in residential PEV ownership and driving activities to enable strategic deployment of new charging infrastructure. Driver agents consider their own driving activities within the simulated environment, in addition to the presence of charging stations and the vehicle ownership of others in their social network, when purchasing a new vehicle. Aside from conventional vehicles, drivers may select among multiple electric alternatives, including two PEV options. The Chicagoland area is used as a case study to demonstrate the different deployment scenarios are analyzed.

52465.全球汽车卤素灯照明市场报告(2014-2018年)
[汽车制造业,电气机械和器材制造业] [2013-12-21]
Halogen lamps are the most popular and widely used form of automotive lighting. These lamps are made of non-metal chemicals that are highly reactive and poisonous. They have a tungsten filament and a glass filament that is filled with halogen gas. Halogen lamps are primarily used in automobiles as the light emitted by these lamps is extremely bright, which improves the visibility for automobile drivers. They also have a much longer life than regular lamps, are cost-effective, and are easily available in the market. Halogen lamps have been adopted across all geographies, and hence automobile manufacturers have been using halogen lamps in automobiles for more than a decade.

52466.全球自适应巡航控制系统(ACC)市场报告(2014-2018年)
[计算机、通信和其他电子设备制造业,汽车制造业] [2013-12-21]
ACC is a driver assistance system that is incorporated into a vehicle to help the driver maintain constant speed and keep safe distance from other vehicles. ACC automatically manages vehicle speed if there is any obstruction in front of the car and warns the driver in an emergency. The purpose of installing an ACC system is to enhance safety and efficiency. It is designed to help prevent accidents caused by driver error such as poor reaction time and drowsiness. This system is highly efficient in warning a driver whenever required and in providing improved comfort during long drives.
