Performance Investigation of Series-Parallel Type PHEV Using Virtual Integrated Development Environment
In this study, design procedure and performance of a series-parallel type plug-in hybrid electric vehicle (PHEV) are investigated using the virtual integrated development environment (VIDE). First, the powertrain model of the target PHEV is constructed using the provided component library in the VIDE. Component parameters are determined based on the objective vehicle performance such as the maximum speed, hill climbing ability, acceleration performance etc. In addition, control algorithm and a full car simulator are developed for the target PHEV. The VIDE full car simulator is validated by AVL CRUISE software. Using the VIDE simulator, performance of the PHEV component and mode control algorithm are investigated and modifications on design parameters and mode control algorithm are proposed to improve the fuel economy.
