Systems and methods automatically rescale an original engine model so that it models an engine of a different size. The original engine model may be coupled to an engine controller model, and the systems and methods may also rescale the original controller model to produce a rescaled controller model matched to the rescaled engine model. The original engine model may include engine parameters and engine lookup tables, and the original controller model may include controller parameters and controller lookup tables. Rescaling factors indicating the size of the new engine being modeled may be received, and ratios may be computed as a function of the rescaling factors. Original engine parameters and controller parameters may be rescaled based on the ratios. Original engine lookup tables and controller lookup tables may be reshaped based on the ratios.

A computer-implemented simulation method is described for testing a driving program for the at least partial autonomous guidance of a test vehicle. The test vehicle is moved by the driving program on a simulated road. A second vehicle in the simulation method is moved as a function of control commands of a user. The test vehicle and the second vehicle are displayed to the user including the road, data relating to the guidance of the test vehicle being collected and stored during the simulation method. A system is also described.
