Dynamic modelling and simulation of THS II based on CRUISE software

A dynamic model is created for evaluating THS II developed by Toyota based on AVL CRUISE software. Using the combination simulation of CRUISE and MATLAB/Simulink, the distinct advantage of THS II belonging to the double planetary gear system can be obviously found out. THS II was installed in Lexus GS450h and has two operation modes. Simulation Results showed superior performance of the proposed THS II in hybrid vehicle. It improved vehicle acceleration and significantly reduced fuel consumptions comparing to THS belonging to the single planetary gear system. Meanwhile, using the practical data of THS II verifies the feasibility of the model.
