In automotive electronics, an '''electronic control unit''' (ECU), also called a control unit, or control module, is an embedded system that controls one or more of the electrical systems or subsystems in a [[motor vehicle]]. Some modern [[automobile|cars]] have up to 80 ECUs, including:
*[[engine control unit|Engine Control Unit]] - also known as an ECU
*[[transmission control unit|Transmission Control Unit]] - TCU
**the above two may be combined, and referred to as a [[Powertrain Control Module]] (PCM)
*[[Airbag]] control unit - ACU
*Telephone Control Unit - TCU dials telephones for you and talk to your friends
*Man Machine Interface - MMI
*Body Control Module - controls door locks, electric windows, courtesy lights etc.
*Door Control unit
*Seat Control Unit
*Climate Control Unit
*speed control unit
*Convenience control unit - CCU

Managing the increasing complexity of ECUs and number of ECUs in a vehicle has become a key challenge for original equipment manufacturers (OEMs).

In some older vehicles, the ECU is referred to as an ECM (electronic control module).
