Development of the “More Electric Automobile” is continuing at an unprecedented pace, with motors, power electronics, and software controls replacing all-mechanical vehicle systems. Waiting until a physical prototype is available to develop test programs that verify system performance is unacceptable. Virtual prototypes can be a helpful tool when making critical design decisions for sizing and integrating components from various disciplines. In addition, they also help define and develop adequate testing strategies and apparatus. This presentation demonstrates the integration of brushless DC or induction motors; digital, analog and power electronics; vehicle mechanical dynamics; and control software with a complete LabVIEW vehicle drive-cycle test program.
