The main contributions of this paper are the development of a forward-looking hybrid vehicle simulation tool, and its application to the design of a power management control algorithm. The hybrid electric vehicle simulation tool (HE-VESIM) was developed at the Automotive Research Center of the University of Michigan to study the potential fuel economy and emission benefits of the parallel hybri...

A series hybrid city bus with diesel engine and electric batteries is studied on a specified route. The study uses two different basic control strategies, " On/off " and " Continuous " strategy. These basic strategies are complemented in two ways. First, an " Adviser " strategy which filters the driver commands and gives driver support feedback based on the route data. Second, an " Adapter " st...

Hybrid electric vehicles, plug-in hybrid electric vehicles, and battery electric vehicles offer the potential to reduce both oil imports and greenhouse gases, as well as to offer a financial benefit to the driver. However, assessing these potential benefits is complicated by several factors, including the driving habits of the operator. We focus on driver aggression, i.e., the level of accelera...

Plug-in hybrid electric vehicles (PHEVs) are gaining increasing interest for both residential and commercial transportation applications. In PHEV design, energy storage system (EES) is a critical component which will impact the overall design efficiency, performance, cost and etc. This dissertation aims to design an advanced energy storage system for a small plug-in hybrid electric vehicle, who...

In this paper, a novel Equivalent Consumption Minimization Strategy (ECMS) is developed for a series hybrid powertrain system, based on the flow of energy through energy sources and components. The performance of the controller is assessed using both urban and highway drive cycles, through comparing results for the series hybrid powertrain system against a comparable conventional powertrain. Fu...

Abstract This paper describes the methods of improving efficiency powertrain like energy management system and control a Parallel Hybrid Powertrain, in order to address growing problem carbon emissions from vehicles on earth protect environment. These developments improvements are necessary for vehicles. Then further analyzed previous method, predicted made future plan next step research by usi...

Plug-in hybrid electric vehicle (PHEV) technology has the potential to help address economic, environmental, and national security concerns in the United States by reducing operating cost, greenhouse gas (GHG) emissions and petroleum consumption from the transportation sector. However, the net effects of PHEVs depend critically on vehicle design, battery technology, and charging frequency. To e...
