1, ECU electronic control unit, also known as "trip computer" and "vehicle computer". In terms of use, it is a special microcomputer controller for automobiles. Like ordinary computers, it consists of microprocessor, memory, input/output interface, analog-to-digital converter and large-scale integrated circuits such as shaping and driving.
2.ECU collects the working state information of various parts of the engine through various sensors and sends it to ECU through transmission lines. After receiving these signals, ECU will analyze all kinds of signals, and then know what state and operation information the engine components are in, and then automatically calculate them according to the pre-written program.
3. In this state, which execution components should be allowed to do what, and then send instructions to the execution components to command them to work.
