Engineers building next-generation fuel cell, hybrid electric, and plug-in hybrid electric vehicles must optimize fuel economy and performance while containing development costs. To meet these goals, they need to simulate multiple powertrain configurations without building costly physical prototypes.
In response to this need, Argonne National Laboratory (Argonne) collaborated with leading auto-makers to develop the Powertrain System Analysis Toolkit © (PSAT), an automotive engineering tool that evaluates a vehicle's fuel economy and performance by simulating its transient behavior and control system characteristics. The U.S. Department of Energy (DOE) Vehicle Technologies Program funded the development of PSAT and uses PSAT as its primary vehicle simulation tool for all FreedomCAR and 21st Century Truck Partnership activities.
Using Simulink® and other MathWorks products, Argonne researchers not only developed PSAT; they also distributed the many complex simulations needed to evaluate vehicle performance in a multiprocessor environment. Distributing the hundreds of simulations required for each vehicle enabled them to get results much more quickly.
