MCU (Media Control Unit) is the primary computer system in Tesla vehicles responsible for managing the infotainment system, user interface, and various vehicle controls. It handles functions such as touchscreen display, navigation, music playback, climate control, and over-the-air software updates. The MCU connects with other vehicle components to provide a seamless user experience and is critical for both driver and passenger interaction with the car’s features. In cybersecurity, the MCU is a potential target for attacks aiming to compromise vehicle systems, access personal data, or disrupt normal operations. Securing the MCU is essential to protect against unauthorized access, data breaches, and potential manipulation of vehicle functions.
