应用系统辨识与理论建模相结合的方法，建立了车辆传动系及其部件的动力学模型，并在Ｍａｔｌａｂ／Ｓｉｍ ｕｌｉｎｋ 环境支持下，建立了车辆传动系动力学仿真系统。该系统可以模拟不同换挡控制规律下的车辆性能，并针对各种换挡控制算法模拟车辆换挡的动态过程，为换挡规律的开发、换挡动态过程的控制和电控液力自动变速器的研究提供了方便。
Based on the method of system identification and theoretical modeling, the dynamics model of vehicle driveline and its components was established. And the dynamic simulation system of vehicle driveline was established with the support of Matlab / Simulink environment. The system can simulate the performance of vehicles under different shift control laws and simulate the dynamic process of vehicle shift for a variety of shift control algorithms. In order to develop shift schedule, control shift dynamic process and electronic control hydraulic automatic transmission The research provided convenience.
