Hardware-in-the-loop verification environment for heavy-duty hybrid electric vehicles

Abstract

This paper presents an implementation of a versatile hardware-in-the-loop verification environment for heavy-duty hybrid electric vehicle (HEV) control software development. The verification environment is located at university facilities, and it consists of full-scale HEV systems that can be loaded with either an electric motor dynamometer or a programmable chassis dynamometer. Model-based software development tools and rapid control prototyping hardware are used to control the test bench hardware and to develop and execute control software. The verification environment can also be used e.g. to measure the efficiency of electric traction motors, power electronic converters, energy storages, and hydraulic pumps.
