Item CITYELEC: A global solution approach for the electrification of urban mobility in Spain(2011) Iglesias, I.; Valera, J. J.; INNOV_AIR_MOBILUrban mobility electrification is a high complex optimization problem, which needs to be approached from an integrated point of view in terms of electric infrastructure and electric vehicle fleet connection. In a first stage is necessary to define the high level specifications, and the optimal size for both infrastructure and electric vehicle fleet, according to the sustainable mobility expected targets of the city analyzed, e.g. mobility covered/filled areas, emission reduction, consumption reduction, cost reduction, energy & mobility efficiencies. In order to obtain the optimum integrated solution, a global approach of the problem is essential, moving from the high level definition of electric vehicle fleet and infrastructure, to the more detailed definition of systems and subsystems derived. CITYELEC is a strategy R&D Spanish project, analyzing, covering and solving the particular urban mobility electrification problem in some cities of Spain, starting from the high level definition of the urban mobility issues, and concluding in the detailed definition of the vehicle and infrastructure specifications. In CITYELEC project, special methodologies, global modelling and simulation tools, and advanced systems and subsystems are being under research and development, aiming for the optimum electro mobility integrated solution, including the infrastructure and the electric vehicle fleet.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.

Under preventive safety, cooperative assistance systems increase in-vehicle integrated safety systems functionality, enlarging driver's time-space perception as well as the quality and reliability of the environment data, and therefore enhancing his response to incoming events. In this paper, an on-board driving assistance system that brings traffic light information inside the vehicle is presented. Making use of positioning and cooperative I2V communications technologies, this system predicts the forthcoming traffic light state and assists the driver by means of an intuitive graphical interface (HMI).Item Modelling and control of a semi-active suspension system(Kluwer Academic Publishers, 2014-01-01) Colina, A.; Lerma, G.; Cabanes, I.; Iglesias, I.; Petuya, Victor; Petuya, Victor; Pinto, Charles; Pinto, Charles; Lovasz, Erwin-Christian; Lovasz, Erwin-Christian; INNOV_AIR_MOBILThe suspension system is composed of several deformable elements such as springs and dampers, which connect the car body to wheels and absorb vibrations generated by road irregularities. The main purpose of suspension system is to isolate the vehicle body from disturbances in order to keep wheels in contact with the road surface to contribute to road holding, and in order to maximize passenger ride comfort. This paper describes a semi-active suspension system of 2 degrees of freedom (2DOF), typically referred to as a quarter car model. To design a suspension control system that improve ride comfort, dynamic modelling of semi-active suspension was developed. Control strategies were implemented for these semi-active suspension systems using MATLAB® and Simulink® software. The results show that the semi-active suspension system controlled by a logical strategy minimizes vertical acceleration experienced by passengers, compared to passive suspension system.Item Networked clean vehicles, how the environment information will improve fuel efficiency and CO2 emissions(2009) Iglesias, I.; Isasi, L.; Larburu, M.; Martin, A.; Peña, A.; INNOV_AIR_MOBIL; CCAM; POWERTRAIN; Tecnalia Research & InnovationInternational goals of reducing CO2 emissions in vehicles require sophisticated solutions in areas not strictly related to an improvement in the efficiency of the powertrain systems, but to an enhanced management of these systems, taking into account parameters of the environment provided by the infrastructure and/or other vehicles. The addition of infrastructure parameters into the control of the vehicle, obtained by means of innovative solutions such as vehicle to vehicle, infrastructure to vehicle (V2V - I2V) cooperative communications, has a significant potential to reduce the CO2 emissions. Notable benefits in the fuel consumption are shown in this paper founded on the implementation of three different advanced driver assistance systems (ADAS), enhanced by using cooperative communications, in a virtual vehicle.Item Novel approach for designing adas - Case study: Forward collision warning with driver-in-the-loop under virtual driving environment(2009) Larburu, M.; Iglesias, I.; Isasi, L.; Peña, A.; POWERTRAIN; INNOV_AIR_MOBIL; CCAM; Tecnalia Research & InnovationADAS will increase their complexity in a short medium term, which will consequently involve changes in the design methodology. The aim of this paper is to present a novel approach when designing ADAS. The case study analysed will show how preliminary design deficiencies, related with acceptability and usability, are early detected. Furthermore, this paper also describes how ADAS can be initially designed within a virtual environment where driver-in-the-loop is possible, having positive impact on the final system driving safety requirements. The benefits of this study are shown on a simplified example based on forward collision warning system designed ad-hoc.
