Development of pure electric vehicle powertrain controller based on hardware in the loop platform

With characteristics of high efficiency, low energy consumption and zero emission, pure electric vehicle is an effective solution for the recent energy crisis and environmental issues. This paper develops a pure electric vehicle control strategy that will be used on ENRANGER G3 — a compact SUV model by Wei Chai Motor. A hardware in the loop (HIL) test platform was constructed accordingly. The platform includes those mathematical models of major electrical components and those HIL´s hardware boards where the plant model is running. Control model was then tested comprehensively and verified on the real vehicle later. The testing results prove that HIL test can significantly reduce the development time and effort, while improve the quality of the control strategies at the same time.
