what is An electronic control unit and What is the different type of ECU?(ECM, PCM, BCM, TCM, …)

Electronic control unit (ECU) An electronic control unit (ECU) is a small device inside a vehicle that controls one or several electrical systems in that vehicle. It tells electrical systems what to do and how to operate. ECU’s core is a microcontroller and it is controlled by embedded software. How does it work? An electronic control unit receives input from one or several parts of the vehicle and uses that information to take action if needed. For example, an airbag ECU receives information from crash sensors and seat sensors. When there is a crash, the ECU decides which airbags to deploy depending on where passengers are sitting. Then it tells the actuators to deploy them. Then the actuators convert the electrical signal into the physical value needed, using valves, injectors or relays. Vehicles may contain over 100 ECUs that in addition to essential functions, like engine performance and power steering, control comfort and security features, such as parking assistance, memory seats and airbag deployment. the different type of ECU: -Generic Industry Controller Naming - Is the naming of controllers where the logical thought of the controller's name implies the system the controller is responsible for controlling -Generic Powertrain The Generic Powertrain pertains to a vehicles emission system and is the only regulated controller name. -Door control unit (DCU) -Engine control unit (ECU) — not to be confused with electronic control unit,[4] the generic term for all these devices -Electric Power Steering Control Unit (PSCU) — Generally this will be integrated into the EPS power pack. -Human–machine interface (HMI) -Powertrain control module (PCM): Sometimes the functions of the -Engine Control Unit and transmission control module (TCM) are combined into a single unit called the Powertrain Control Module. -Seat Control Unit -Speed control unit (SCU) -Telematic control unit (TCU) -Transmission control module (TCM) -Brake Control Module (BCM; ABS or ESC) -Battery management system (BMS)
