In the last Years, there is the awareness that the migration to Model-based approach, allowing to System engineers and the Software engineers the use of the same executable model as working paper throughout the development process from requirements capture and specification to coding and test, is the only possibility to address the real needs of the Sw Embedded development Process (continue Specification changes, unrealistic schedule, cost reduction). Besides, in today's commercial vehicle development process, the enhancement of the vehicle or the realization of new line is obtained through the introduction of Safety critical electronics Systems. The ISO 26262 aims to ensure the functional safety related electronics systems in the Road Vehicles.Other side, the ISO 12207 describes the processes that should occur during the life cycle of a software development process from its conceptualization through its retirement. It fills the critical need to have a common approach to manage and engineer any software item.As ISO standards, the 26262 and 12207 do not specify formally whether to use given development process or specific validation tools but provide only recommendations.The paper focuses on the identification of a named “Automotive Sw Life Cycle” where each phase will include a series of activities, intended to satisfy the ISO Standard 26262 and 12207. Each activity will be done through a specific customization of Model-Based Commercial tools allowing the tailoring of the International Standards to the real needs of the OEM.The IVECO approach places emphasis on the encapsulation of commercial tools, properly customized in the various phases of the traditional Sw development process, leading to faster production of high quality code and minimization of cost associated with the Software Development Process according the ISO Standards 26262 and 12207.
