This report contains evaluations of four light vehicle stability and control simulations developed for the National Highway Traffic Safety Administration (NHTSA): FOROL developed by Dynamic Research Inc., the "Intermediate Maneuver Induced Rollover Simulation" (IMIRS) and the "Advanced Dynamic Vehicle Simulation" (ADVS), both developed by the University of Missouri, and "Vehicle Dynamics Analysis, Non-Linear" (VDANL) developed by System Technology, Inc. The focus of these evaluations is each simulation's ability to accurately predict light vehicle responses during flat road handling and crash avoidance maneuvers. Each simulation is first described on an analytical basis. The overall modeling approach is described along with detailed descriptions of the modeling of the vehicle subsystems. For each simulation, any areas found to be inadequately modeled are reported. The ability of each simulation to predict flat road vehicle responses is evaluated by comparing the simulation predictions to experimentally measured vehicle responses. These comparisons are done in both the time and frequency domains. The intent of this report is only to evaluate the capabilities of each simulation in its current form, and recommend a direction for future work in this area. It is not the intent of these evaluations to determine if the developers of the simulations met the requirements of their contracts.
