摘要
汽车主动安全和一体化安全系统的开发复杂且费时。荷兰国家应用科学研究院(TNO)发明了一种基于仿真工具和测试设备的无缝结合,用于设计和评估主动安全及一体化安全系统的新方法,以保证开发流程的有效性和高效率。该方法使用的主要工具包括:PreScan软件、VeHIL试验室和MADYMO软件。该方法将真实生活中的事故统计数据和用户需求转换成系统设计,进而预测真实生活的事故发生率和损伤等级。试验结果已被用来验证仿真模型。经过验证的仿真模型,可用于设计和测试系统,预测系统在真实生活中的作用效果,定义最终验证该系统所需的试验矩阵。案例演示了如何将这些工具一起应用于主动安全及一体化安全系统的开发流程中。
Developing active and integrated safety systems for automobiles is a complicated and time- consuming activity. TNO （The Netherlands Organization for Applied Scientific Research） has created a new methodology for design and assessment of active and integrated safety systems to make the development process more effective and efficient. The main tools used within the method are PreScan, VeHIL and MADYMO The method is based on seamless integration of simulation tools and test facilities to convert real world accident statistics and/or user requirements to a system design and, from there, to a prediction of real-world accident rates and injury levels. Experimental results are used to validate the simulation model. The validated simulation model is then used to design and test the system to predict the system＇s real world effects, and to define the set of experiment needed for final verification of the system. Concrete examples demonstrate how these tools can together be applied in the development process of active and integrated safety systems.
