ECU (Electronic Control Unit)

An Electronic Control Unit (ECU) is a small computer within a vehicle that manages and controls specific functions, such as engine operation, braking systems, or safety features. It receives information from sensors, processes this data, and then sends commands to various components to ensure optimal performance, efficiency, and safety. Think of it as the vehicle’s central nervous system—coordinating and regulating key operations seamlessly to keep the car running smoothly. Different ECUs handle different systems, working together to maintain the vehicle’s overall functionality.
