Item Development and validation of dynacar RT software, a new integrated solution for design of electric and hybrid vehicles(2012) Pena, A.; Iglesias, I.; Valera, J. J.; Martin, A.; Tecnalia Research & Innovation; INNOV_AIR_MOBILVehicle 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.Item Development and validation of Dynacar RT software, a new integrated solution for design of electric and hybrid vehicles(2012) Pena, A.; Iglesias, I.; Valera, J.

El chasis rodante virtual(2013-03) Iglesias-Aguinaga, Inaki; Martín-Sandi, Adrián; Pena-Rodríguez, Alberto; INNOV_AIR_MOBIL; Tecnalia Research & InnovationTools enabling early validation and error detection are becoming ever more necessary due to the increasing pressure on carmakers to reduce development time. Vehicle parts or systems testing, based on a complete virtual vehicle software model connected with the test bench, can allow for validation in very life-like conditions depending on the model used, which may in turn reduce traditional testing times (whether on the bench or around the track) and help with the early detection of design faults and validation. This testing approach involves the choice of a vehicle modelling approach which allows a model to be obtained with a suitable computing speed to be performed in real time, together with suffi cient precision for the results to be comparable with trials carried out on the real vehicle. This study will examine the modelling process carried out within the development of a validation tool based on a complete vehicle model, together with the conclusions obtained through a comparison with studies on real vehicles. The development of this strategy led to the concept of the virtual rolling chassis. The validity both of the modelling approach based on the virtual rolling chassis together with the fi nal model obtained, was confi rmed by means of a comparison with real tests carried out on the test track. There was an appropriate results correlation between the virtual tests obtained in the driving simulator and those obtained with the real vehicle.
