摘要 在本文的第一部分 ,介绍了一种理想的车辆动力系统的计算机辅助开发过程。它显示了现代仿真技术在产品持续发展过程中的作用 ,该技术采用硬件回路作非在线的仿真 ,并通过现代化的试验手段对车辆进行匹配。特别重要的是提供了将电控变速器和发动机控制单元综合的可能性。接着是在线仿真在诸如发动机和变速器模式方面的应用和发展 ,它是上述开发过程的基础。根据上述的方法论 。 In the first part of the article, an idealized computer aided development process for the entire powertrain of a vehicle is presented. It is shown how state of the art simulation techniques can contribute to a continuous development process, which is based upon offline simulation using hardware in the loop, the utilization of the possibilities to link electronic transmission and engine control units.\;Then there will be a report of the application and development of real time simulation models, such as engine models and transmission models, which are essential modules for the development process mentioned above.\;Based upon the described development methodology, applications that have already been implemented and further possible applications of this holistic development process are covered.
