In this paper, a new control strategy for energy management in Plug-in Hybrid Electric Vehicles (PHEVs) using Fuzzy Cognitive Map (FCM) is presented. In this strategy, FCM is used as a supervisory control such that the State of Charge (SoC) of the battery is kept in the acceptable range and fuel consumption per kilometer is reduced, in addition to providing the request power. Since this method ...

Plug-in hybrid electric vehicle (PHEV) technology may reduce fuel consumption and tailpipe emissions in many mediumand heavyduty vehicle vocations, including school buses. The true magnitude of these reductions is best assessed by comparative testing over relevant drive cycles. The National Renewable Energy Laboratory (NREL) collected and analyzed real-world school bus drive cycle data, and sel...

In order to support drivers in adopting a more fuel efficient driving style, there currently exists a range of fuel economy displays, providing drivers feedback on instantaneous and longterm fuel consumption. While these displays rely almost completely on visual components for conveying relevant information, we argue that there are significant benefits in using auditory interfaces for providing...

This paper presents a freeway driving cycle (FDC) construction method based on traffic information. A float car collected different type of roads in California and we built a velocity fragment database. We selected a real freeway driving cycle (RFDC) and established the corresponding time traffic information tensor model by using the data in California Department of Transportation performance m...

In this paper thermodynamic modeling and comprehensive performance analysis of a real integrated solar combined cycle (ISCC) power plant are performed. Performance of the plant cycle is assessed in off-design condition and in two operation modes of power-boosting and fuel-saving. Such an approach has not been considered for an ISCC plant in the previous studies. Under studied ISCC which is loca...

Challenges facing fuel cell hybrid vehicles is in implementing a control strategy to find the optimal split of power between the different power sources. This paper proposes a mathematical model of power flow in such vehicles taking into consideration power train losses. Linear programming locates the global optimum indicating the finest synchronization among power units in an attempt to lower ...

Optimization based control methods for Plug-in Hybrid Electric Vehicles require the knowledge of an entire driving cycle and an elevation profile to obtain the optimal performance over fixed driving route. In this paper, the method using traffic information to predict the future driving cycle and the optimal control strategy based on Pontryagin’s Minimum Principle (PMP) are investigated in orde...

Hybrid vehicle fuel economy and drive quality are coupled through the “Energy Management” controller that regulates power flow among the various energy sources and sinks. This paper studies energy management controllers designed using Shortest Path Stochastic Dynamic Programming (SP-SDP), a stochastic optimal control design method which can respect constraints on drivetrain activity while minim...
