A driving simulator (DS) provides driving experience to a driver. Doing so, a DS performs motion in a limited workspace while the true world driving maneuver would require more space. State of the art DS show design immanent high system mass and costs. Thus, the world-wide use of such systems is very little and is in conflict with the recent trend of development of advanced driver assistant systems. New DS designs are required allowing for high driving experience quality and a wide range of maneuvers that can be performed while reducing costs significantly. The execution of the new DS design demands the analysis of open questions. Hence, the applicant did research since 2010 regarding feasibility of the new DS design by simulation and experimental test. As a result of this research a development environment of an omnidirectional motion base was developed that allows for further fundamental research. The research goals are the investigation of the new wheeled mobile DS design in order to explore new applications for driving simulation and the increase of the world-wide use due to the reduced costs. Furthermore, the gained knowledge enables the development of an unscaled prototype with extended visual representation system and a dome for the encapsulation of the test person.Central questions of research:a) Which dynamic limits result from the wheeled mobile DS design? Which influence quantities constitute those limits?b) Does the new design allow for the application on undergrounds with higher macro unevenness (conventional roads or proving grounds)? What chassis measures have to be considered to allow for application on pavements that provide less surface finish? Which compensatory measures have to be considered due to the introduced degrees of freedom of the chassis suspension in order to avoid unwanted interconnection with the seating platform of the driver?c) What possibilities exist to optimize the Motion Cueing for the usage within provided workspaces with different size? How does the quality of the provided driving experience depend on those measures?d) How does a general safety system for the new motion base look like when considering constraints like limited workspace and the carriage of humans with acceptable risk? Which detailed designs are suitable for implementation?e) What merits/drawbacks are to be expected when substituting the conventional visual representation system with head mounted displays?

驾驶模拟器(DS)为驾驶员提供驾驶体验。这样做，DS在有限的工作空间内进行运动，而真正的驾驶动作需要更多的空间。最先进的DS显示设计内在的高系统质量和成本。因此，这类系统在世界范围内的使用非常少，与最近先进的驾驶员辅助系统的发展趋势相冲突。需要新的DS设计，以实现高驾驶体验质量和广泛的操作范围，同时显著降低成本。新DS设计的实施需要分析开放的问题。因此，申请人从2010年起通过模拟和实验测试对新DS设计的可行性进行了研究。作为这项研究的结果，开发了全方位运动基座的开发环境，为进一步的基础研究奠定了基础。研究的目标是研究新的轮式移动DS设计，以探索驾驶模拟的新应用，并因降低成本而增加世界范围内的使用。此外，所获得的知识使开发具有扩展的视觉表示系统和用于封装测试者的圆顶的未缩放原型成为可能。研究的中心问题：a)轮式移动DS设计产生了哪些动态限制？哪些影响量构成了这些限制？b)新设计是否允许在宏观不平度较高的地基上应用(常规道路或试验场)？必须考虑哪些底盘措施才能在表面光洁度较低的路面上应用？由于引入了底盘悬挂的自由度，必须考虑哪些补偿措施，以避免与驾驶员的座椅平台发生不必要的互连？c)在提供的不同大小的工作空间内，存在哪些可能性来优化运动提示的使用？提供的驾驶体验的质量如何取决于这些措施？d)当考虑到有限的工作空间和可接受风险的载人等限制时，新运动基础的一般安全系统看起来如何？哪些详细设计适合实施？e)用头盔显示器取代传统的视觉表现系统时，预计会有哪些优点/缺点？
