What does the automotive ECU mean?
1 Answers
Automotive ECU is the onboard computer, whose components include a microprocessor, memory, input/output interface, analog-to-digital converter, as well as shaping and driving circuits. The function of the automotive ECU is to compute, process, and judge the information input from the air flow meter and various sensors based on the programs and data stored in its memory, then output commands to provide the fuel injector with electrical pulse signals of a certain width to control the fuel injection volume. The ECU has self-diagnosis and protection functions. When a system failure occurs, it can automatically record the fault code in RAM and take protective measures to read substitute programs from the aforementioned inherent programs to maintain engine operation.
