Vehicle Stability Controller HiL Validation on Static Simulator

Authors: Federico Alfatti, Claudio Annicchiarico, Renzo Capitani

In the automotive world, Hardware in the Loop (HiL) methodologies are used to speed up the design and calibration process of the various mechatronics components installed on the vehicle.

Installing production parts on advanced driving simulator enables the performance assessment in realistic scenarios, including a test driver earlier in the design process.

The scope of this work is to evaluate the effect of ABS and ESC system, replicating their influence on the steering wheel.

A brake by wire production system has been installed on a static simulator, equipped with a EPSiL steering bench, capable of accurately replicate tie-rod forces on a production steering unit.

Full brake, sine steer maneuvers have been carried out both on real vehicle and on virtual environment.

The system showed its capabilities of replicating the same functionalities of the real vehicle, extending the static simulator potentialities to support the activities on calibration and test of vehicle systems.
