Anthony and John J. Moskwa University of Wisconsin-Madison Eugene Danielson U.S. Army TACOM Copyright © 1998 Society of Automotive Engineers, Inc. ABSTRACT Powertrain simulation is becoming an increasingly valu- able tool to evaluate new technologies proposed for future military vehicles. The powertrain of the M1A1 Abrams tank is currently being modeled in the Powertrain Control Research Laboratory (PCRL) at the University of Wisconsin-Madison. This powertrain model is to be inte- grated with other component models in an effort to pro- duce a high fidelity simulation of the entire vehicle. INTRODUCTION The powertrain system model described in this paper was developed by the researchers in the Powertrain Con- trol Research Laboratory (PCRL) at the University of Wisconsin-Madison for the U.S. Army’s TACOM Automo- tive Research Center (ARC). The powertrain system model is to be integrated with other vehicle components in a complete vehicle simulation. These models were created using Simulink, a graphical programming pack- age, from The Mathworks, Inc. By using a graphical pro- gramming environment, equations describing the dynamics of a component can be grouped together in a block, or module. These modules can then be coupled together to represent subcomponents. This is essential to satisfy the goal of integrating vehicle s
