Item A "context evaluator" model for a multimodal user interface in driving activity(2011) Murgoitio, Jesús; Urquiza, Arkaitz; Larburu, Maider; Sánchez, Javier; CCAM; ROBOTICA_FLEX; POWERTRAIN; Tecnalia Research & InnovationFocused on new HMI for vehicles, this paper explains the methodology followed by Tecnalia to provide an evaluation of the context, based on sensors data, in order to achieve the optimum usability and ubiquity levels at any given moment, and finally to optimize the driving task from the safety point of view. The paper is divided into three sections. Firstly, there is an introduction in which the main concepts, multimodality and Ambient intelligence, are explained (section 1), and this is followed by the two projects related to the work shown here (section 2). In section 3 we will go on to describe the methodology used to obtain an evaluation of the context, as is necessary for a car HMI with multimodal capabilities. Finally, a particular "Context evaluator" is displayed in order to illustrate the methodology and report the work carried out.Item Eco-Routing Android Application to Promote the Usage of Light Electric Vehicles in Urban Environments Within the Framework of the STEVE European Project(Springer Science and Business Media Deutschland GmbH, 2021) Arteta, Beñat; Parra, Alberto; Prieto, Pablo; Larburu, Maider; Heriz, Borja; Coupeau, Alvaro; POWERTRAIN; Tecnalia Research & InnovationNowadays, the high level of atmosphere pollution strongly influenced by industry and transportation is one of the most relevant social problems. In order to reduce the amount of pollutant discharged into the atmosphere, some technological breakthroughs have been developed in vehicle electrification area. The main objective of the European project STEVE is to introduce Electrified L-category Vehicles in urban transport systems. However, the main drawback is their limited driving range thus, optimal energy management systems are crucial here. In this paper the newly developed Eco-navigation Android application, which generates the most optimal route based on speed and elevation profiles for use in e-bikes, will be presented. The Eco-routing app is going to be implemented in Calvià (Mallorca, Spain) during 2020.Item Safe road trains for environment: Human factors' aspects in dual mode transport systems(2010) Larburu, Maider; Sanchez, Javier; Rodriguez, Domingo José; POWERTRAIN; Tecnalia Research & Innovation; Tecnalia Ventures S.L.After being widely applied in aviation, automation is increasingly applied to surface transportation. Furthermore, with the increased reliability and reduced cost of electronics and communications, it is becoming viable to develop a safe and reliable platooning system. These intelligent systems of the future will contribute to improved safety, efficiency, and journey time of vehicles while at the same time reducing stress for passengers. However, although new technologies make vehicle platooning possible, these new technologies will require interaction with drivers. Therefore, the development of appropriate Human - Machine Interfaces (HMI) progressively assumes greater importance, as diverse and innovative technologies are designed and implemented in vehicles. As a result of this interaction there is a need to research human aspects and the HMI. The main objective of this study consists of analyzing human aspects involved in vehicle platooning. Accordingly, this paper describes the human factors issues that come into play when introducing autonomous driving. A further study objective is to develop a high-quality HMI, and assess the effectiveness of the HMI, including the acceptability level from possible end-users point of view. This study is part of the European project "Safe Road Trains for the Environment, SARTRE", that aims to define several platoon requirements attributable to the driver's opinion, as well as to define the necessities to develop an appropriate HMI for a platooning environment. This takes into account information coming from objective parameters, logged during the simulation tests, and the driver preferences derived from acceptability assessment.Item Safe road trains for the environment (SARTRE): Validation of SARTRE Platoon service and the SARTRE HMI(2012) Larburu, Maider; Urquiza, Arkaitz; Sanchez, Javier; POWERTRAIN; ROBOTICA_FLEX; Tecnalia Research & InnovationEver since the electronically coupled vehicles concept was introduced in 1998, besides the increased reliability and reduced cost of electronics and communications, it is now feasible to develop a safe and reliable platooning system, which includes specific Human-Machine Interface (HMI) for platoon vehicles. However, the development of new and sophisticated in-vehicle systems fostered by technical innovation demands careful validation of these systems. Whereas excellent system performance may be sufficient for the technician, it is as important that the equipment is appealing and accepted by the driver. It is unproductive to invest effort in designing and building a driving support system if the system is never switched on, or even disabled. Consequently, the aim of this study is to validate the acceptance of the SARTE platoon service and the developed HMI for a platooning environment within the European project SARTRE [1]. Taking into account potential end-users point of view, was evaluated the following indicators: usefulness, satisfying level, understanding level, ease of use, perceived safety and workload, by means of an Acceptance Scale questionnaire, Technological Acceptance Model questionnaire, etc., in order to collect the self-reported data after platoon driving tests. This was allowed thanks to this study was conducted in a driving simulator, under virtual environment.Item Validation methodology focussing on fuel efficiency as applied in the eCoMove project(2012) Themann, Philipp; Isasi, Lucía; Larburu, Maider; Trommer, Stefan; Vreeswijk, Jaap; Wilmink, Isabel; CCAM; POWERTRAINThis paper discusses the validation approach applied in the eCoMove project (a large scale EU 7th Framework Programme project). In this project, applications are developed that on the one hand optimise network-wide traffic management and control, and on the other hand advise drivers on the most efficient routes and assist them in applying an eco-friendly driving style. The applications are validated using different test methods: with (small scale) field trials, driving simulator studies and microscopic traffic network simulations. In order to perform a consistent and integrated validation and impact assessment, a validation approach based on the FESTA methodology was developed that combines all these elements. The aim is to validate whether a complete eCoMove system can reduce fuel consumption and CO2 emissions by 20%.
