基于VxWorks的PCI设备驱动程序开发

对嵌入式实时系统VxWorks中的设备驱动程序开发进行了简要的介绍，讨论了VxWorks操作系统下的I／O系统和设备驱动程序、应用程序之间的关系。另外，结合作者开发PCI9054时统卡驱动程序的实际，讨论了VxWorks下PCI设备驱动程序的框架，并详细介绍了各个模块的具体实现。     

Mobile phone use while driving: public opinions on restrictions

This paper reviews two road-user surveys on the use of mobile phones on the road in Finland where the mobile phone ownership rate is highest in the world (70% in August 2000). From 1998 to 1999 the proportion of drivers that chose to use a mobile phone while driving rose from 56% to 68%, while the proportion of phone using drivers who experienced dangerous situations due to phone use rose from 44% to 50%. The proportion of drivers who used their phones in some way to benefit safety on the road remained at about 55%. The youngest, novice drivers had the highest level of phone usage of all age categories. Over 48% of the interviewees believed that the government should ban the use of hand-held mobile phones while driving, and another 27% believed that all types of mobile phone use should be banned while driving. Those drivers who used their phones the most each day were more likely to want some form of restrictions, than those who had lower usage. This is a strong message to the elected lawmakers and raises the problem of exactly how regulatory bodies would go about controlling the future growth of new driver support and non-driving related communication devices in road vehicles. It was concluded that legislating for hands-free use only would be a reasonable course of action. Mandating that the current generation of equipment should be optimized for hands-free use should result in future generations of in-vehicle equipment also being optimized for hands-free use as a minimum criterion.     

VxWorks下显卡(69030/815)高分辨率与双屏驱动程序的开发

对VxWorks下图形驱动ML3．0进行了比较深入的研究，在此基础上提高了Chips 69030显卡和Intel 815显卡在VxWorks下图形驱动的分辨率，并实现了在VxWorks下Chips 69030显卡和Intel 815显卡双屏驱动的开发，具有较高的实用价值。     

Driver requirements and road traffic informatics

Initially the driver's role as a link in the driver-vehicle-road-traffic control-chain is discussed in a historical perspective. The gradual changes and the advantages and problems arising from these changes are discussed from behavioural point of view.Then the driver tasks are analyzed. A separation is made between trip planning, navigation, road following, traffic interaction, rule compliance, other than traffic tasks, car handling and speed choice. The relations between and the weights of these subtasks are discussed. Some existing driver behaviour models are reviewed in relation to the above mentioned tasks.Finally an effort is made based on the analyses of driver tasks and driver models to specify some general and some more specific potential advantages and problems with expected future RTI-systems.

“教学做合一”教学模式在汽车维修专业课教学中的实践

随着我国中等职业教育的发展与普及,学校对于学生的成绩要求降低,这也就在一定程度上导致所招收的学生综合素质能力水平不足。而在学习过程中,由于学生的学习基础较差、学习兴趣不足,影响专业技术的教学,不利于中职院校课堂教学的发展与进步。要想当前对教育教学形式,满足老师老师的教学需求,就要对中职院校的教学模式进行改变与创新。而"教学做合一"的教学模式能够通过实践活动、以学生为教学中心,引导学生主动参与到课堂教学当中,有效的提高课堂教学质量与效率。本文通过对"教学做合一"的教学模式的内涵和特征进行分析,进一步进行"教学做合一"教学模式在汽车维修专业课教学中的探索与实践。     

中高职类院校机械产品设计类专业学生专业技能的培养与研究

现代社会迅猛发展的过程中,逐渐对人才提出了更高的要求,不仅要学生掌握较多的理论知识,而且还要具备较高的专业技能水平。所以,中高职类院校对机械产品设计类专业学生培养时,应转变以往的教学理念,对专业技能培训产生高度重视,进而向社会输送更多高素质的专业技能型人才。基于此,本文通过对机械产品设计类专业学生应具备的专业技能的简单介绍,进而制定出相应的培养策略,为提升学生的专业节能奠定良好基础。     

智能汽车的人机共驾技术研究现状和发展趋势

智能汽车的人机共驾技术（HMIoIV）是解决其智能化级别难以快速跨越至高度自动化水平的有效过渡手段。HMIoIV涉及了L0~L3级别的智能汽车的多种自动化技术,包括先进辅助驾驶系统。针对当前国内外智能汽车人机共驾技术的研究现状,对其概念、结构和研究内容进行总结,根据独立驾驶人参与的数量和驾驶操作方参与的数量将现有的人机共驾技术分成3类：单驾双控结构、串联型双驾单控结构（Traded Control）和并联型双驾双控结构（Shared Control）;并对驾驶人为因素、驾驶人模型、自然驾驶人状态监测和驾驶意图识别、串联型双驾单控结构和并联型双驾双控结构的研究方法以及权限与责任的关系进行全面综述。最后,分析总结当前智能汽车的人机共驾技术所面临的问题和挑战,并对该技术的发展趋势做出展望。
