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 ,本文论述了仿真技术已取得的成绩和将来的应用可能性 In the first part of this paper, an ideal computer-aided development process of vehicle powertrain is introduced. It shows the role of modern simulation technology in the continuous development of the product, which uses hardware circuits as off-line simulations and matches the vehicle with modern tests. It is particularly important to provide the possibility of integrating the electronic control transmission with the engine control unit. This is followed by the application and development of online simulations, such as engine and transmission modes, which underlie the development process described above. According to the above methodology, this article discusses the achievements of simulation technology and the possibility of future applications
