Abstract
To accommodate computer graphics delays, the future position and orientation of a simulated vehicle are predicted in an operating sequence by separate coordinated models that are fed data signals indicating the operator's control actions. The control actions are extrapolated to provide further data signals. A suspension model and a nonlinear chassis model operate sequentially with a road model to provide one reference-state input to a prediction model. Other inputs to the prediction model are from the drive train and steering extrapolation units controlled by driver inputs.
