Plug-in hybrid electric vehicles (PHEVs) have demonstrated the potential to significantly increase fuel economy. However, the overall efficiency of the powertrain system of any Hybrid Electric Vehicle (HEV) depends on the vehicle-level control strategy. To optimize the energy flow, a global optimization algorithm, based on the Bellman principle, was used to generate the most efficient operating...

Most navigation systems use data from satellites to provide drivers with the shortest-distance, shortest-time or highway-preferred paths. However, when the routing decisions are made for advanced vehicles, there are other factors affecting cost, such as vehicle powertrain type, battery state of charge and the change of component efficiencies under traffic conditions, which are not considered by...

Current legislation in European countries, as well as in other parts of the world, is putting stricter limits on pollutant emissions from road vehicles. This issue, in conjunction with the increase awareness of consumer for the environmental problems, will require the development of new clean propulsion systems in disruption with the current mobility solutions based on internal combustion engin...

VPSET (Vehicle Powertrain Systems Evaluation Tool) is vehicle modeling and simulation software to analyze performance and fuel economy of conventional and hybrid powertrains. VPSET has a Graphical User Interface (GUI) to guide the user during building a vehicle model. This paper discusses VPSET, its organization, structure, vehicle templates and presents validation results for select vehicles.

Finite element models of a simplified vehicle-like structure have been used for preliminary investigations of the likely impact of vehicle bodyshell materials and structures on invehicle low frequency magnetic fields, such as those associated with currents flowing on the high voltage power cables of vehicles equipped with electric powertrain. The simulations reported here consider frequencies u...

Techniques for testing cyberphysical systems (CPS) currently use a combination of automatic directed test generation and random testing to find undesirable behaviors. Existing techniques can fail to efficiently identify bugs because they do not adequately explore the space of system behaviors. In this paper, we present an approach that uses the rapidly exploring random trees (RRT) technique to ...

This paper proposes a practical solution to address the energy management issue in fuel cell hybrid electric vehicles (FCHEVs). revolves around powertrain system that contains (FC) as main supply, photovoltaic (PC) secondary source, and battery bank (Batt) backup storage compensate for FC’s low response rate. The this alternated between designated elements load via DC bus, maintain stable outpu...
