We propose routing algorithms for plug-in hybrid electric vehicles (PHEVs) that account for the significant energy efficiency differences of vehicle operating modes and recommend the predominant mode of operation for each road segment during route planning. This is to enhance fuel economy and reduce emissions. We introduce the Energy-Efficient Routing problem (EERP) for PHEVs, and formulate thi...

Plug-in Hybrid Electric Vehicles (PHEVs) offer a great opportunity to significantly reduce petroleum consumption. The fuel economy of PHEV is highly dependent on All-Electric-Range (AER) and control strategy. Previous studies have shown that in addition to parameters influencing Hybrid Electric Vehicles (HEVs), control strategies of PHEVs are also influenced by the trip distance. This additiona...

Plug-in hybrid electric vehicle (PHEV) technology will provide substantial reduction in petroleum consumption as demonstrated in previous studies. Platform engineering steps including, reduced mass, improved engine efficiency, relaxed performance, improved aerodynamics and rolling resistance can impact both vehicle efficiency and design. Simulations have been completed to quantify the relative ...

In this study, electric-drive vehicles with series powertrains were configured to utilize a lithiumion battery of very high power and achieve sport-sedan performance and excellent fuel economy. The battery electrode materials are LiMn2O4 and Li4Ti5O12, which provide a cell area-specific impedance of about 40% of that of the commonly available lithium-ion batteries. Data provided by EnerDel Corp...

We introduce a practically important and theoretically challenging problem: finding the minimum cost path for plug-in hybrid electric vehicles (PHEVs) in a network with refueling and battery switching stations, considering electricity and gasoline as sources of energy with different cost structures and limitations. We show that this problem is NP-complete even though its electric vehicle and co...

Plug-in hybrid electric vehicles (PHEVs) are hybrid electric vehicles that can be fueled from both conventional liquid fuels and grid electricity. To represent the total contribution of both of these fuels to the operation, energy use, and environmental impacts of PHEVs, researchers have developed the concept of the utility factor. As standardized in documents such as SAE J1711 and SAE J2841, t...

This work deals with the longitudinal comfort issue of a plug-in hybrid vehicle and in particular with the control of driveline oscillations caused by gear shifts. The rear drive torque generated by a motor is used to compensate the effect of clutch opening and closing. Takagi-Sugeno (TS) method is used to approximate the nonlinear longitudinal dynamics model. Simulations using a detailed vehic...

A 78-year-old man presented at Eulji University Hospital due to an abdominal aortic aneurysm with maximum diameter of 52 mm, which had been increased from 45 mm over 6 months. He underwent embolization of the left internal iliac artery with vascular plug, prior to endovascular abdominal aortic repair with a bifurcated stent graft system. Unfortunately, the inserted vascular plug was maldeployed...
