Design and Implementation of Virtual Hybrid Electric Vehicle Simulator for Educational Purpose

Abstract

The objective of this paper is to describe the development of an educational purpose computer- based simulator for Hybrid Electric Vehicle (HEV) technology. The tremendous capital investment, tedious and time-consuming tasks required to establish a full function of HEV laboratory are convincing evidence that the HEV curriculum is in need of a low-cost, computer- based virtual HEV simulator. An interactive, LabVIEW-based simulation software was developed for different configurations of hybrid powertrains under several driving conditions. The developed software is capable of simulating, illustrating and displaying (on the PC-based screen) the multiple energy flows in the HEV based on its configuration and driving conditions. The software integrated with actuator assembles the simulator which serves as a hands-on experience unit for multidiscipline students enrolled in the HEV technology courses. The virtual HEV simulator not only enhances the HEV training and education, but also increases students’ interest in the green movement of transportation.

1. Introduction

World competition and stringent United States fuel economy goals and emission regulations for the 21st Century vehicle have pressured the automotive industry to design and evaluate advanced automobiles at an accelerated rate. The industry consensus is that the hybrid electric vehicle is the currently available technology for increasing propulsion system efficiency and decreasing pollutant emissions [1-2]. However, HEVs operate much differently than conventional vehicles. Therefore, existing design and maintenance techniques and guidelines developed for conventional powertrains do not apply well to hybrid vehicles. There is a need for training automotive technicians and engineers as well as educating students in this new and emergent technology of HEV.

Recently, the Department of Engineering Technology in one university has received a National Science Foundation grant, joint with one community college, to develop courses and degree programs for training community college instructors and automotive technicians in HEV technology. The university developed a set of courses for community college instructors and automotive engineers, and the community college is the first community college in the state – and one of the only in the nation – to train automotive technician students on servicing HEVs [3]. However, no integrated HEV laboratory has yet been established for educational purposes. The tremendous capital investment, tedious and time-consuming tasks required to establish a fully function of HEV laboratory are convincing evidence that the community colleges and secondary schools are in need of a low-cost, computer-based virtual HEV simulator.

The motivation of this project is to develop an interactive, LabVIEW-based [4] simulation software for different configurations of hybrid powertrains under several driving conditions. The
