SDM010 Electronic Control Unit

SDM010 Electronic Control Unit, also known as the ECU (Electrical Control Unit), is the core component of the automotive engine electronic control system. Its main function is to calculate, process and judge all kinds of information input by each sensor of the engine according to its own stored program, and then output instructions to control the relevant actuator action, so as to achieve the purpose of fast, accurate and automatic control of the engine work.

The ECU is mainly composed of input loop, A/D converter, microcomputer and output loop. The input loop is responsible for receiving the signal from the sensor, performing pre-processing operations such as clutter removal and waveform conversion, and then converting the processed signal into a voltage signal. The A/D converter converts the analog signal into a digital signal for computing processing by the microcomputer. The microcomputer is the core part of the ECU, which performs arithmetic processing according to the memory program and data, and sends the processing result to the output loop. The output loop drives the actuator according to the instructions of the microcomputer to control the working state of the engine.

By collecting the sensor parameters of the engine, such as engine speed, speed, water temperature and other parameters, after analysis and processing, the ECU controls the fuel injection time, ignition time, etc., in order to achieve the best working state of the engine. At the same time, the ECU will also diagnose the fault of the engine and take corresponding protective measures to ensure the safe operation of the engine.

In general, as the core component of the electronic control system of the automobile engine, the ECU plays an important role in achieving the best working state of the engine and ensuring the safe operation of the engine.
