The increasing of the number of lines of code in modern vehicles, due to the will of building more complex functionalities, has led to an increasing difficulty in writing hand-written code and to the development of the Model Based Software Design technique, based on the automated code generation from abstract models built following a specific visual language describing the desired behavior. This thesis, carried out in Brain Technologies, describes the application of such approach to the development of an AUTOSAR-compliant software component implementing the control of the front windshield wiper and in its functional testing through Model-, Software- and Processor-in-the-loop simulations.
