Objectives and Results
Development of a new methodology for testing hybrid power transmissions by networking test benches. At the end of the project, the partners will be provided with a guideline that will enable them to network their test benches and test hybrid powertrains in early stages of development.
Content and Approach
Within the project, test benches for electric and combustion engines are to be networked across locations. With the help of higher-level complete vehicle models, entire hybrid powertrains can be mapped by networking the individual test benches. Besides the mechanical and electrical parameters, the thermal conditioning of the relevant system components is one of the main areas of research.
At the beginning, the boundary conditions are investigated. This involves working out which communication methods are possible and which interfaces and additional functionalities must be implemented on the test benches. The requirements for the hardware and the corresponding test cases are also defined. In the further course an exemplary networking is realized at the involved institutes.
The test cases will be used to test this networking and record the measurement data. In order to verify the methodology, these are compared with the measurement data of a comparable hybrid vehicle in combination with a complete vehicle test bench. Finally, the evaluation is carried out in close cooperation with the industrial partners, the elaboration of the guideline and a detailed documentation.
