DEVELOPMENT OF AN ENGINE SOUND ENHANCEMENT ALGORITHM FOR VEHICLES AND ITS DEPLOYMENT ON ARDUINO

Nowadays, supercar sound requirements, demanded by the market and customers, are extremely high and in most cases, they cannot be achieved only by modifying the engine features in the design phase. A good way to achieve these goals is using Active Sound technology. This work, carried out in collaboration with McLaren Automotive, focuses on the development of an Engine Sound Enhancement algorithm: the main goal has been to create a working Simulink model that takes the CAN bus data as input and from these, it synthesizes a sound output inside the cockpit through the speakers in order to enhance the original engine sound features. Subsequently, the implementation on Arduino was carried out in order to replicate a physical application of the generated model. The final step concerned writing a second Arduino sketch to implement also the AVAS (Acoustic Vehicle Alerting System).
