基于Simdriveline的汽车无级变速传动系统的建模与仿真

The CVT Modeling and Simulation based on Simdriveline

Matlab2006a中发布了基于汽车物理建模的工具箱Simdriveline,从实时控制的角度出发应用此工具箱建立无级变速器(Continuously Variable Transmission)的智能驾驶员、速比控制模型,和传动系统及整车动态模型,并仿真计算汽车在跟踪给定行驶方式下的动态过程,为进一步开发无级变速器的控制策略提供必要的前期工作准备。

A real-time CVT model including ratio control algorithm, intelligent driver model, powertrain and vehicle dynamics is established by the Simdriveline tool box which was released in newest version matlab2006a of Matlab on the theory of physical modeling. Based on the model, the dynamic responses are simulated under several given condition. And the corresponding results are very important for designing the control strategy and investigating the related control algorithm.
