An electronic control unit (ECU) receives input from: Sensors Other control units Output devices Both \( A \) and \( B \)

An electronic control unit (ECU) is a marvel of modern engineering that acts like the brain of your vehicle or device. It's responsible for making sure everything runs smoothly by receiving input from various sensors that monitor things like temperature, speed, and pressure, as well as from other control units that help coordinate complex functions. Think of it as your automobile's command center, always processing data to keep everything in harmony! In the real world, ECUs are not just limited to cars. They're increasingly found in household appliances like smart refrigerators and washing machines, making them "smarter" by monitoring and optimizing performance. For instance, in an electric vehicle, the ECU processes input from battery sensors to regulate charging and power distribution, ensuring an efficient and safe ride. It's fascinating to see how these tiny units play huge roles in our daily tech!
