What does ECU mean in a car?
1 Answers
ECU in a car refers to the onboard computer, which is essentially a specialized microcomputer controller for automotive purposes. The ECU has self-diagnostic and protection functions. When a system failure occurs, it can automatically record fault codes in RAM, read substitute programs from its memory to maintain engine operation, and display fault information on the dashboard. This allows car owners to identify problems and drive the vehicle to a repair shop for maintenance. In S-class sedans, ECUs are not only used in engines but can also be found in many other systems, such as anti-lock braking systems, four-wheel drive systems, electronically controlled automatic transmissions, active suspension systems, airbag systems, and multi-directional adjustable electrically controlled seats - each equipped with their own ECU.
