Modeling and simulation for electric vehicle powertrain controls
This paper reviewed the main stream of commercial software for electric vehicle simulation and briefly discussed the advantage of physical modeling tool. A dynamic simulation model of electric vehicle (EV) was developed using Matlab/Simulink and SimPowerSystem/SimDriveline toolbox. The EV model has a configurable structure that is suitable to simulation with multiple fidelity levels. This advantage will combine simulation models associated with deployment and test for different controllers to a single platform. It has multiple running rates and different solvers for subsystems in order to speed up simulation. The electrical system model is capable to simulate power electronics behavior both on average and switching level. An automated mechanical transmission (AMT) model and its controller were developed for heavy duty application, such as a city bus. It can simulate drive train discontinuous behavior (e.g. clutch engage/disengage) and longitudinal vibration.
