An Electric Vehicle Dynamic Simulation 820779

A complete electric vehicle dynamic simulation has been developed for evaluating the performance of drive train components and control strategies. The simulation includes models for the drive motor and its field controller and armature chopper, the battery, a transmission, and a transmission actuator and associated transmission control to accomplish automatic gear changes. These component models along with a vehicle dynamics model provide simulated vehicle performance in response to driver commands. The simulation provides a tool for developing control algorithms, and serves as a basis for examining other electric vehicle problems. The modular structure readily allows adding or substituting component models so that other hardware configurations can be studied.
