Abstract: For hybrid vehicles, it is difficult to obtain realistic component models and actual interaction between subsystems without carrying out experiments. INRETS has performed a coupled approach associating simulation using its in house VEHLIB software together with experimental validation. This paper highlights the evaluation and modelling of the Toyota Hybrid Systems (THS) used in the 2004 Prius vehicle. First, the ICE, battery, boost converter, and strategy evaluation and validation process to obtain a useful model of the vehicle are examined. Then examples of application are presented concerning energy flow in the vehicle and engine operation compared to a conventional car.

Keywords: hybrid vehicles; modelling; Toyota Prius; fuel consumption; battery modelling; hybrid powertrain management; model validation; energy flow; simulation.
