Development of a model for hybrid electric vehicle powertrain

Abstract

Hybrid Electric Vehicles (HEVs) having power-split architectures have come up with a promising solution to address environmental concerns and energy efficiency in the automotive industry. This project focuses on the development of a comprehensive Simulink model for a power split HEV powertrain, aiming to provide a versatile platform for analysis and optimization. The Simulink model incorporates essential components such as internal combustion engine (ICE), electric motor(s), power electronics, energy storage systems (ESS), and transmission mechanisms, capturing the complex interactions among these elements. Detailed sub-models are developed to simulate the dynamic behavior of individual components and their integration within the powertrain system. Key objectives include accurate representation of power flows, energy management strategies, and control algorithms to optimize fuel consumption and vehicle performance. Model validation is conducted through fuel consumption comparison against existing HEV systems i.e. Toyota Prius 4th Generation system. The developed Simulink model serves as a valuable tool for HEV powertrain design, allowing engineers to explore various configurations, assess the impact of component specifications, and evaluate control strategies in a virtual environment. Additionally, it facilitates research and development efforts toward advancing HEV technology, contributing to the realization of more sustainable and efficient transportation solutions.
