Sistema adaptativo de gestión de energía basado en laseparación de frecuencias para vehículos eléctricosPublicada el 15/04/2015

Publication date: 15 April 2015. Source: Journal of Power Sources,Volume 280. Author(s): Adrian Florescu , Seddik Bacha , Iulian Munteanu ,Antoneta Iuliana Bratcu , Axel Rumeau. This paper deals with an adaptivefrequency-based power sharing method between batteries andultracapacitors (UC) as power sources within an electric vehicle. Anadaptive frequency splitter is used for routing the low-frequency content ofpower demand into the battery and its high-frequency content into the UCsystem, taking profit from the UC as a peak power unit. Autonomy maythus be increased while preserving battery state of health and ensuringthat UC voltage variations remain confined within certain desired range.Results obtained by real-time experiments on a dedicated test rig validatethe proposed energy management approach and recommend it to beapplied as power source coordination method to microgrids in general.

Planificación de la trayectoria y control de seguimiento paramaniobra autónoma de cambio de carril en base a sistemacooperativo de infraestructura en un vehículoPublicada el 03/04/2015

Publication date: 3 April 2015. Source: Expert Systems with Applications.Author(s): Feng You , Ronghui Zhang , Guo Lie , Haiwei Wang , HuiyinWen , Jianmin Xu Lane change maneuver is one of the most conventionalbehaviors in driving. Unsafe lane change maneuvers are key factor fortraffic accidents and traffic congestion. For drivers’ safety, comfort andconvenience, advanced driver assistance systems (ADAS) are presented.The main problem discussed in this paper is the development of anautonomous lane change system. The system can be extended applied inintelligent vehicles in future. It solves two crucial issues – trajectoryplanning and trajectory tracking. Polynomial method was adopted fordescribing the trajectory planning issue. Movement of a host vehicle wasabstracted into time functions. Moreover, collision detection was mappedinto a parameter space by adopting infinite dynamic circles. The secondissue was described by backstepping principle. According to the Lyapunovfunction, a tracking controller with global convergence property wasverified. Both the simulations and the experimental results demonstrate thefeasibility and effectiveness of the designed method for autonomous lanechange.

Reacción a una situación crítica durante la conducción conContro de Crucero Adaptativo para usuarios y no usuarios delsistemaPublicada el 01/02/2015

Publication date: February 2015. Source: Safety Science, Volume 72. Author(s): Giulio Francesco BianchiPiccinini , Carlos Manuel Rodrigues , Miguel Leitão , Anabela Simões. Adaptive Cruise Control (ACC) is asystem that maintains driver-selected speed and headway to a preceding vehicle. The system presents somelimitations that are, in part or totally, unknown to the users. Hence, many drivers exhibit a rudimentary mentalmodel of the system and place excessive trust in the device. As a consequence, negative effects on roadsafety can easily occur. However, to date, many studies conducted on ACC have comprised participants whohad never used ACC previously. Therefore, there is limited knowledge of how ACC affects the drivingperformance of experienced users of the system. To shed light on this point, twenty-six participants, dividedinto two groups (ACC users and non-users) drove twice in the simulated environment (once with the ACC andonce manually). During both drives, the participants experienced a critical situation (stationary vehicle stoppedin the cruising lane of the highway). The results show that negative behavioural adaptations to the ACCresulted from the usage of the system with regard to the critical situation: the risk of collision during the drivingwith ACC was increased compared with the manual driving for both groups of drivers. Besides, the researchstresses the negative large correlation between the driver’s mental model of ACC operation in the criticalsituation and the safety margins maintained by the ACC users during the same situation. Finally, it was foundthat the drivers’ trust in the system does not have an influence on the drivers’ behaviour during the trial with theACC.

Análisis experimental del rendimiento de baterías en base a litiopara vehículos de carretera eléctricos e híbridosPublicada el 31/12/2014

Publication date: 31 December 2014. Source: Applied Energy, Volume136. Author(s): Clemente Capasso , Ottorino Veneri. This paper deals withan experimental evaluation regarding the real performance of lithiumbased energy storage systems for automotive applications. In particularreal working operations of different lithium based storage systemtechnologies, such as Li[NiCoMn]O2 and LiFePO4 batteries, are comparedin this work from the point of view of their application in supplying fullelectric and hybrid vehicles, taking as a reference the well-known behaviorof lead acid batteries. For this purpose, the experimental tests carried outin laboratory are firstly performed on single storage modules in stationaryconditions. In this case the related results are obtained by means of abidirectional cycle tester based on the IGBT technology, and consent toevaluate, compare and contrast charge/discharge characteristics andefficiency at constant values of current/voltage/power for each storagetechnology analyzed. Then, lithium battery packs are tested in supplying a1.8kW electric power train using a laboratory test bench, based on a 48VDC bus and specifically configured to simulate working operations ofelectric vehicles on the road. For this other experimentation the test benchis equipped with an electric brake and acquisition/control system, able torepresent in laboratory the real vehicle conditions and road characteristicson predefined driving cycles at different slopes. The obtained experimentalresults on both charge/discharge tests and driving cycles demonstrate theadvantages of using lithium technologies, mainly in terms of their highefficiency, particularly at high current values. That represents a feasiblesolution to offer vehicle designers and users extended driving ranges andreduced recharging times. Graphical abstract Highlights

Comparación entre estrategias de gestión energética paravehículos eléctricos con sistema de almacenamiento de energíahíbridaPublicada el 01/12/2014

Publication date: 1 December 2014. Source: Applied Energy, Volume 134. Author(s): Ziyou Song , HeathHofmann , Jianqiu Li , Jun Hou , Xuebing Han , Minggao Ouyang. This paper deals with the real-time energymanagement strategies for a hybrid energy storage system (HESS), including a battery and a supercapacitor(SC), for an electric city bus. The most attractive advantage deriving from HESSs is the possibility of reducingthe battery current stress to extend its lifetime. To quantitatively compare the effects of different controlstrategies on reducing battery degradation, a dynamic degradation model for the LiFePO4 battery is proposedand validated in this paper. The battery size is optimized according to the requested minimal mileage, while thesize of SC is optimized based on the power demand profile of the typical China Bus Driving Cycle (CBDC).Based on the optimized HESS, a novel fuzzy logic controller (FLC) and a novel model predictive controller(MPC) are proposed and compared with the existing rule-based controller (RBC) and filtration based controller(FBC), after all the controllers are tuned to their best performance along the CBDC. It turns out that FLC andRBC achieve the best performance among the four controllers, which is validated by the DP-based result.Furthermore, about 50% of the HESS life cycle cost is reduced in comparison with the battery-onlyconfiguration. In addition, the controllers are also compared along the New European Driving Cycle (NEDC),which represents another normalized driving cycle. The results show that the RBC, MPC, and FLC achieve asimilar performance, and they reduce about 23% of the HESS life cycle cost when compared to the battery-only configuration. The RBC and FLC are regarded as the best choices in practical applications due to theirremarkable performance and easy implementation.
