Concept analysis & system design of a hybrid electric vehicle with virtual test driving

Abstract

In this paper, an open integration and test platform is used for the multi-objective optimization of the powertrain concept of a hybrid vehicle. This was done for different driving scenarios and driver types and taking into account longitudinal and lateral vehicle dynamics. A comparative study of fuel efficiency and performance for a hybrid-electric powertrain with different battery sizes and operating strategies was made, using the Functional Mockup Interface (FMI) approach to integrate a detailed vehicle powertrain model into a comprehensive full-vehicle model driven by a virtual driver on a virtual road.
