China Junjie seat belt computer board is usually located under the gear lever before and after:

1. ECU (Electronic Control Unit) electronic control unit, also known as "driving computer", "vehicle computer", etc. . In terms of purpose, it is a special microcomputer controller for automobiles. It is the same as an ordinary computer, consisting of a microprocessor (CPU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D), shaping, driver, etc. Made up of large scale integrated circuits. To describe it in a simple sentence, "ECU is the brain of the car";

2. ECU uses various sensors (including temperature sensor, pressure sensor, rotation sensor, flow sensor, position sensor, oxygen sensor, explosion sensor, etc.) (vibration sensor, etc.) collects the working status information of each part of the engine and sends it to the ECU through the transmission line. After the ECU receives these signals, it will analyze the various signals, and then it will know the functional status of each component of the engine and the operation status of the engine, and then automatically calculate according to the pre-written program;

3. In this state, which execution components should be allowed to do what, and then instructions are sent to the execution components to order the execution components to work.
