On the basis of the shifting process of automated mechanical transmissions (AMTs) for traditional hybrid electric vehicles (HEVs), and by combining the features of electric machines with fast response speed, the dynamic model of the hybrid electric AMT vehicle powertrain is built up, the dynamic characteristics of each phase of shifting process are analyzed, and a control strategy in which torq...

E CONOMIC and environmental incentives, as well as advances in information and control technologies, are reshaping the traditional view of transportation systems. The emergence of plug-in hybrid electric vehicles (PHEVs) and plug-in electric vehicles (PEVs) has shown that electrification is a clear trend to improve performance, efficiency, and sustainability of transportation systems since elec...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

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...

This report explores pathways to reducing transportation based carbon dioxide emissions in the United States. The goal is to analyze the feasibility of reducing the level of transportation based carbon dioxide emissions in 2050 to 50% of the level they were at in 2005. Emissions have been steadily rising over the past century, and if left uncurbed, will have a negative effect on the quality of ...

Policymakers, consumers and manufacturers are all agreed – the auto industry needs to adopt electrification to address climate change and dwindling natural resources – yet we still see very few hybrid and electric vehicles on the road today. Given the will is there, why the lack of adoption? In reality the main reason is not the technology, but rather the cost of developing the technology in th...
