What is the use of ECU?

[Ricky]

ECU (Electronic-Control-Unit) is an electronic control unit, also known as the "on-board computer" or "vehicle computer". In terms of its purpose, it serves as a dedicated microcomputer controller for automobiles. Below is relevant information about ECU: 1. The main component of ECU is a microcomputer, with the CPU being its core element. The ECU converts input signals into digital form, processes them by comparing with stored reference data, calculates output values, and then amplifies the output signals to control various regulating servo components such as relays and switches. 2. Essentially, an ECU is an "Electronic Control Unit", composed of three parts: an input circuit, a microcomputer, and an output circuit. The input circuit receives signals from sensors and other devices, filters, processes, and amplifies these signals, then converts them into input levels of specific voltages.
