Modeling of a series hybrid electric high mobility multipurpose wheeled vehicle

In an effort to reduce fuel costs and gas emissions, the US Army is looking into replacing their diesel high mobility multipurpose wheeled vehicle (HMMWV) with hybrid electric vehicles (HEVs). The aim of this paper is to present the design of a series hybrid electric vehicle similar to the hybrid electric HMMWV (HE-HMMWV) and to build a multi-domain simulation model of the design using Ansoft Simplorer™. Emphasis is placed on the vehicle´s transient response to desired speeds dictated by drive cycles based on UDDS and SAE J227a Schedule D. Emphasis is also placed on vehicle´s response to hill climbing up to 60% grade.
