Real time processing in Simulink for Hardware in the Loop simulations of V2X

Vehicle-to-everything (V2X) communications allow vehicles to exchange messages useful for several scopes, including accident reduction and safety applications. This feature, in cooperation with advanced driver assistance systems (ADAS), needs to be tested and validated to guarantee optimal functionality. This thesis focuses on the development of a Simulink V2X simulation communication module, as an extension to the traffic simulator adopted as part of a validation platform, with the aim of interfacing it with hardware devices. The traffic simulator generates the scenario and controls, through a protocol defined in this activity, an external simulator, which in turn activates the exchange of V2X messages. The system is then tested by applying, as an example, a forward collision warning (FCW) application. More specifically firstly, simulations have been developed in a software in the loop (SiL) architecture; finally, a hardware in the loop (HiL) setup has been implemented, involving real on-board units (OBUs), with a tablet simulating human-to-machine interface (HMI).
