Bass Allison Transmission Division of General Motors ABSTRACT Until recently, U.S. government efforts to dramatically reduce emissions, greenhouse gases and vehicle fuel consumption have primarily focused on passenger car applications. Similar aggressive reductions need to be extended to heavy vehicles such as delivery trucks, buses, and motorhomes. However, the wide range of torques, speeds, and powers that such vehicles must operate under makes it difficult for any current powertrain system to provide the desired improvements in emissions and fuel economy. Hybrid electric powertrains provide the most promising, near-term technology that can satisfy these requirements. This paper highlights the c onfiguration and benefits of a hybrid electric powertrain c apable of operating in either a parallel or series mode. It de scribes the hybrid electric components in the system, including the electric motors, power electronics and batteries. In addition, the paper illustrates the installation of th is hybrid electric hardware into a 17,000 kg (GVW) military vehicle based on an RV chassis. The analyses of the new system show that conventional benchmarks for performance and fuel economy can be met or exceeded. In fact, fuel economy increased 50 percent on an urban cycle and 25 percent on average for five different cycles. Finally, the benefits of this powertrain for military initiatives such as the 21 st Century Army and 21st Century Truck Initiative will be discussed, including how the Dual-Use Hybrid Electric Command and Control Vehicle can provide a source for up to 150 kW of auxiliary electrical power. INTRODUCTION—FUTURE ARMY AND 21ST CENTURY TRUCK The U.S. Army recognizes t hat the old way of fighting wars with massive buildups of vehicles will be replaced by a new type of scenario. T hat scenario will consist of fast response strike forces engaging small terrorist bands. This type of operation will require that troops and vehicles be able to get in and get out of enemy territory fast. Integral to th is type of mission profile is the requirement that vehicles penet rate dr
