Advanced DVP for E-Axles - How to Strengthen Confidence in Virtual Validation

Alwin Tuschkan, AVL List GmbH

The inclusion of simulation-based or simulation-supported validation can advance the validation process in terms of reducing testing time and the required number of samples. In this presentation and paper a generic advanced model based Design Validation Plan (DVP) for e-axles is introduced. It is shown how simulation can be used to substitute physical testing for design validation and save about 50% of time and cost efforts compared to a generic common European standard validation process. One common testing area with a high potential for virtual validation is the assessment of efficiency. Latest results of an AVL research project regarding an e-motor efficiency mapping are shown and discussed. Focus is the correlation between simulation and measurement and in particular the investigation and comparison of validation confidence including uncertainties of both, virtual and physical validation. These investigations underline the trustworthiness of simulation – which is key to implementing advanced model based virtual validation to the industry.
