Where does data processing take place in an automobile?

Data processing in an automobile primarily occurs in the onboard computer systems, often referred to as the Engine Control Unit (ECU) and other electronic control units (ECUs) throughout the vehicle. These systems gather data from various sensors, such as those monitoring engine performance, vehicle dynamics, and safety features, and process this information to optimize performance, enhance safety, and improve driver experience. Additionally, advancements in technology have led to increased data processing in connected car systems, enabling features like navigation, infotainment, and vehicle-to-everything (V2X) communication.
