Abstract

To build a full vehicle model entirely based on physical equations is a challenge (Dempsey M., 2006). To have this model to run fast enough so that it is suitable for Hardware-in-the-Loop testing is even more challenging. The level of detail in the physical representation of the vehicle can always be increased at the cost of simulation time. Even if the performance of the hardware is constantly improving, we still have to compromise. As part of the MORSE (MOdel based Real-time Systems Engineering) project, model reduction techniques are developed and applied to a vehicle model. The results in terms of accuracy and simulation speed are then investigated.
