Hardware-in-the-loop (HIL) and software-in-the-loop (SIL) simulations have long been used to test electronic control units (ECUs) and software. Now they have a new application field: calibration and parameterization of a vehicle stability controller, using simulation. A virtual calibration procedure like this requires far more precise models and new approaches to optimizing vehicle dynamics, and also raises a lot of development process issues.
