51493.全球手势识别市场的汽车行业报告（2014-2018年）
[信息传输、软件和信息技术服务业,汽车制造业] [2015-03-23]
Gesture recognition refers to the ability of a device to identify and respond to different gestures of an individual. Gesture recognition technology can be classified into 2D and 3D technologies. An invisible infrared light is beamed on the individual facing the camera, and this light is then reflected back to the camera and sent to a gesture recognition IC. The IC along with the gesture recognition software creates a map of the images received and responds to the movements exhibited in front of the camera accordingly. In vehicles, gesture recognition helps provide a high level of safety and a better user-machine interface. The major applications of gesture recognition in automobiles include managing audio and video systems, dashboard management, and managing other interior automobile controls.

51494.全球轮式拖拉机市场报告（2014-2018年）
[专用设备制造业,汽车制造业] [2015-03-23]
A wheeled tractor is a type of heavy equipment used to move asphalt, dirt, snow, logs, raw materials, debris, rocks, and sand during construction and mining activities. These tractors can be easily converted into loaders based on users' requirements. Various tools such as dozer blades, buckets, and rippers can be easily attached to tractors to convert them into bulldozers, front loaders, and front-end loaders.

51495.全球矿业市场推土机报告（2014-2018年）
[汽车制造业,采矿业] [2015-03-23]
Mining dozers remove unwanted materials such as loose earth, soil, and other related particles from the site, which might create an obstruction in the mining process. The bucket attached to the dozers helps dig holes in strategically designated locations. Their firm ground hold makes the dozers a useful piece of equipment in marshy, rough, and rugged terrains.

51496.全球推土机市场报告（2014-2018年）
[专用设备制造业,建筑业,汽车制造业] [2015-03-23]
A bulldozer is a type of crawler equipped with an attached blade to push and move soil, sand, rubble, or other such materials during construction. The claw-shaped ripper is attached to the rear end of the crawler and helps in loosening densely compact materials. Bulldozers are used for different types of infrastructure-related activities including construction of structures, in mines and quarries, and other engineering projects.

51498.电机-变速器一体化传动的换挡试验台架测控系统的设计
[汽车制造业] [2015-03-15]
为实现电机-变速器一体化传动换挡过程的优化控制,开发了其试验台架的测试与控制系统。针对一体化传动换挡过程的特点和功能需求,测控系统采用了上下位机的结构形式。上位机在NI-Labview环境下进行软件功能的设计和控制算法的实现;下位机利用其实时操作系统测量换挡过程的关键信号并输出控制指令。换挡控制采用了分阶段、多目标的协调控制算法,以提高换挡品质。大量换挡试验表明,该测控系统性能稳定,能实现信号的同步采集、数据储存、实时显示、换挡控制和在线调参等功能,为换挡过程建模和控制策略优化提供依据。

51499.机动车非尾气颗粒物排放研究
[汽车制造业] [2015-03-15]
利用MOVES模型研究了北京市机动车的非尾气颗粒物排放随速度的变化规律,结果表明:小客车、小货车、大客车和大货车的非尾气颗粒物排放因子均随着车速的升高而下降。采用统计方法建立了各车型的非尾气颗粒物排放占全部颗粒物排放的比例模型;并应用该模型测算了实施尾号限行措施后,二环路上行驶车辆的非尾气颗粒物排放的变化。结果显示:限行措施实施后,早高峰二环路非尾气颗粒物排放量降低了23.36%;此外,限行前后二环路上非尾气颗粒物排放量所占比例均超过了35%,因此在评估机动车颗粒物污染时,应综合考虑尾气和非尾气两种排放来源。

[汽车制造业] [2015-03-15]
以某型轿车稳定杆为研究对象,采集试车场道路载荷谱并对其进行统计分析,在传统基于广义力的载荷谱编制方法基础上,考虑结构的真实损伤计算,提出一种基于等效应力的编谱方法。通过CAE和台架试验验证可知,寿命与失效位置与实车路试结果基本一致。新方法相比传统方法能更准确预估损伤等效结果,减少试验频次,更快速地模拟出汽车结构件实际受载情况,试验加速效果明显。
