The architecture of the Modular Technical Model (MTM) is also presented, based on a functional subdivision into independent modules (Environment, Plant, Control, HMI and User), which guarantees reusability, scalability and progressive integration throughout the development cycle, in line with the principles of the Extended V-Cycle The thesis then describes the revision activity of the Vehicle.MTM project, divided into several phases: •??reorganization of the Project Lauch Page, a centralized access point from which the user can manage all the preliminary operations necessary for the opening, configuration and launch of the Simulink model; •??reorganization of parameter management through the use of Simulink.Parameter objects and a dedicated Simulink Data Dictionary; •??structuring signals into hierarchical Simulink buses to improve readability, modularity, and traceability; •??study and optimization of CAN communication, with the introduction of automatic configuration and switching mechanisms between virtual and real simulation; •??introduction of an automatic mechanism for updating the Data Dictionary, which ensures consistency between the model and the parameters used
