Development and validation of dynacar RT software, a new integrated solution for design of electric and hybrid vehicles

Vehicle modelling and simulation is becoming a key competence for the development of the electrified vehicle systems, from preliminary designs to implementation and validation phases. Usually different vehicle models are used in design phases, leading to lack of traceability and robustness in the design process. An integrated approach is presented in order to allow automotive engineers to use a single vehicle model from the very beginning of the design to the most severe hardware in the loop and powertrain in the loop requirements. The new modelling concept presented has been validated with a 100kW electric race car in a test track. Validation results compared to simulation predictions are presented in the paper.
