Design trade-off studies were made to determine the relative attractiveness of various hybrid/electric power train configurations and electrical and mechanical drive-line components. Initial screening of the candidate configurations and components was done using a vehicle synthesis computer program. The initial screening was concerned primarily with total vehicle weight and economic factors and identified the hybrid power train combinations which warranted detailed evaluation over various driving cycles. This was done using a second-by-second vehicle simulation program which permitted the calculations of fuel economy, electricity usage, and emissions as a function of distance traveled in urban and highway driving. Vehicle layout studies were also made to evaluate various power train arrangement possibilities in terms of their effect on vehicle handling, safety, serviceability, and passenger comfort. Based on the design trade-off studies, the power train layouts and components were selected for the Preliminary Design Task of the Near-Term Hybrid Vehicle Program. (ERA citation 05:035131)
