Development of an HiL based methodology for design, calibration and validation of ADAS systems

This work proposes a methodology for the early development and validation of Advanced Driver Assistance Systems (ADAS), specifically Autonomous Emergency Braking (AEB) and Lane Centering Assist (LCA), through the integration of real hardware into a driving simulator using a Hardware-in-the-Loop (HiL) approach. The objective is to overcome the limitations of traditional full-vehicle validation, which is typically performed late in the development process and constrained to a limited number of test scenarios. The proposed methodology enables safe, repeatable, and extended scenario testing in earlier stages. It includes the definition of relevant scenarios, functional system decomposition, and the development of dedicated HiL test benches. The approach was applied to a commercial brake-by-wire unit for AEB and to an LCA system with integrated camera sensor, with results compared against real-vehicle track testing. The findings demonstrate reduced development time, expanded design space exploration, and maintained compliance with testing standards and regulations.
