The focus of this paper is the process of implementation and integration of a series-parallel multiple-regime plugin hybrid electric vehicle (PHEV) using a 2013 Chevrolet Malibu as a platform. The University of Victoria EcoCAR team used a 3-year vehicle development process (VDP) modeled after those used by major automotive manufacturers, and maintained by the rules of EcoCAR 2: Plugging into the Future.Intensive research and simulation resulted in selection of UVic's series-parallel multiple regime vehicle architecture during year 1 of the EcoCAR2 competition. Detailed mechanical design refinement has been conducted to allow final fabrication and integration of components. This has included detailed structural analysis and comparison with the stock vehicle, dynamic analysis of vehicle suspension changes, and manufacturability and serviceability improvements to the year 1 vehicle design. Simulation and modeling work to improve the realism of the vehicle simulation for the purposes of control system development was also conducted. Control system development has been focused around moving vehicle control strategies into a more realistic state, including component diagnostics and mitigating strategies resulting from DFMEA (Design Failure Mode Effects Analysis) work results.
