PRIUS混合动力汽车驱动系统键合图建模仿真

Modeling and Simulation of Hybrid Drive System on the Toyota PRIUS Based on Bond Graph

在深入研究丰田公司出产的 PRIU S混合动力汽车驱动系统及其各单元的动态关系的基础上 ,运用键合图原理对该系统进行数学建模 ,并应用 Matlab/ Simulink进行仿真计算和研究。研究表明 ,所建模型可以较准确地反映PRIU S的动态特性 ,并通过发现解决多动力耦合中弹性与柔性耦合影响导致的车速波动 ,证明使用键合图建模的优越性。

Based on the application of bond graph in the hybrid drive system on the Toyota PRIUS is discussed in detail .To solve the mathematic model of the hybrid drive system, the Matlab/Simulink is used. The simulation result showed that using the bond graph could reflect the dynamic characteristic in effect. And the advantage of simulation on bond graph is testified by solving the fluctuation of the result effectually.
