ECU (Electronic Control Unit), also known as "trip computer" and "vehicle computer". In terms of use, it is a special microcomputer controller for automobiles, also called a special single chip microcomputer for automobiles. It consists of microprocessor (CPU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D) and large-scale integrated circuits such as shaping and driving, just like an ordinary single chip microcomputer. The function of the electronic control unit is to calculate, process and judge the information input by the air flowmeter and various sensors according to the programs and data in its memory, and then output instructions to provide the fuel injector with electric pulse signals with a certain width to control the fuel injection quantity. The electronic control unit consists of a microcomputer, input, output and control circuits.

But in some mid-to high-end cars, ECU is not only used in engines, but also can be found in many other places. For example, anti-lock braking system, four-wheel drive system, electronically controlled automatic transmission, active suspension system, airbag system, multi-directional adjustable electronically controlled seat, etc. Are equipped with their own ECU. With the improvement of automotive electronic automation, ECU will increase day by day, and the circuit will become more and more complicated. In order to simplify the circuit and reduce the cost, a technology called multi-channel communication network is adopted to transmit information between multiple ECU on the vehicle, and the ECU of the whole vehicle forms a network system, that is, CAN data bus.

I can't give you the list. A little more detailed is a trade secret. The above systems can be done all over the world, just Bosch.
