HRS - Comparison of hybrid drive systems using real-world validated simulation models
Overview
Background & policy context:
Passenger cars are particularly suitable for the use of hybrid propulsion technology due to the large spread in engine outputs. In addition, a significant reduction in fuel consumption is desirable. Furthermore, low pollutant emissions are attainable with this technology.
Objectives:
The HRS project dealt with a comprehensive analytical comparison of hybrid drive systems of passenger cars. The simulated models have been validated by Real-world measurements.
Methodology:
For this purpose, a preliminary market study was conducted: The different hybrid propulsion technologies which are already in use or in a development status were explored and assessed regarding their market potential. This was followed by the parameterization of existing, detailed Matlab Simulink models for the main variants of the hybrid propulsion technology, under special consideration of the electric motor components. In the study, hybrid drive variants with gasoline and diesel engines, plug-in concepts, and a fuel cell vehicle were compared with an average vehicle with conventional powertrain.
