Development of a Supervisory Control Unit for a Series Plug-in Hybrid Electric Vehicle

<p>A Series PHEV was chosen, as ERAU's entry into EcoCAR2 through a multidisciplinary architecture selection process. The series architecture was chosen for its mechanical feasibility, consumer acceptability and its performance on energy consumption simulations. The Series PHEV architecture was modeled using Matlab, Simulink, and dSPACE ASM tools, to create a plant model for controller development. A supervisory controller was developed to safely control the interactions between powertrain components. The supervisory control unit was tested using SIL and HIL methodologies. The supervisory controller was developed with an emphasis on fault detection and mitigation for safety critical systems. A power management control algorithm was developed to efficiently control the vehicle during charge sustaining operation. The first controller implemented was a simplified bang-bang controller to operate at the global minimum BSFC. A power-tracking controller was then developed to minimize powertrain losses. The power-tracking controller substantially reduced the vehicles energy consumption on simulated EPA drive cycles.</p>
