Abstract
This paper introduces the parameter prediction and modelling methods for the traction motor of hybrid electric vehicle (HEV). In the general HEV simulation, the traction motor is mainly defined by efficiency map and torque/speed curve. Therefore, this paper will focus on the prediction of these parameters, which involves the numerical analysis on the motor inductances calculation, iron-loss resistance calculation, and characteristic estimation algorithm and so on. The modelling method is split into tow major parts: configuration of model and composing graphic user interface (GUI). An experiment result will be used to compare with the calculated efficiency map to verify the validity of these methods. In addition, the model construction will be explained by flowcharts. Considering popularity, the MATLAB/Simulink will be used to construct the simulation program. And a GUI will be designed and used to show the simulation results. With the other models of vehicle components, the simulation will be processed in a parallel-type HEV model in an urban road condition (FTP72), and the simulation results will be shown in the end of this paper.

Summary
Since the Toyota-Prius and Honda-Insight achieve great success in the both environment and economic issues, most of automotive companies have paid much attention on the development of hybrid electric vehicle (HEV) in global. It is difficult to design the control algorithm of HEV, and hard to determine the specification of each component and estimate the overall performance [1] [2]. Based on these problems, it is necessary to develop a HEV simulator in software for testing the prototype design before manufacturing. The calculated efficiency map data will be verified by the experiment data This motor model will be processed with the models of the other HEV components in a parallel-type HEV model in an urban road condition (FTP72). The simulation results will be shown in the end of this paper
