Abstract
In the context of an increasingly competing automotive market, the possibility to reduce powertrain developing time and reducing cost is of paramount importance. To this extent, virtualization of controller development by means of Hardware-in-the-Loop (HIL) systems can consistently contribute in reducing time to market by frontloading and parallelizing verification and validation of electronic control unit at a fraction of the cost of carrying it out on physical vehicle prototypes. For these reasons, Powertech Engineering (PWT) is investing resources in developing methodologies and tools for HIL testing of state-of-the art automotive Electronic Control Units. In this framework, this thesis aim is to setup the first HiL application for the Verification and Validation of an Electric Vehicle Control Unit (EVCU) on the first full-HIL test bench in PWT.
The work was mainly divided into two work-packages: in the first one (referred to as Dyno-mode) only the vehicle’s powertrain has been simulated on the HIL, making the EVCU operating as on a powertrain test bench; In the second (referred as Vehicle mode) the powertrain model was co-simulating with a vehicle model and a rest-of-the-bus emulation model to make the EVCU operating as in the real vehicle
