During the last decade the usage of Embedded System in automotive applications is increased extraordinarily and even in a chip shortage period the trend is to replace classical mechanical system. With this vision, in the following work of thesis will be discussed the development of EVduino, an open-source Vehicle Management Unit with its environment, for automotive applications. The basic idea is to provide the users the possibility of developing applications with the flexibility of model-based design through Simulink with the capability to embed software in an Arduino-like fashion. The fundamental starting point is the ISO 26262 standard for functional safety in road vehicles, in which is described the development of a product in each phase.
