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 subsystems in a vehicle. Some modern cars have up to 70 ECUs, including:

• Engine Control Unit
• also called Powertrain Control Module (PCM)
• Transmission Control Unit - TCU
• Telephone Control Unit - TCU
• Man Machine Interface - MMI
• Door Control unit
• Seat Control Unit
• Climate Control Unit
• speed control unit

Managing the increasing complexity of ECUs and number of ECUs in a vehicle has become a key challenge for OEMs.

"Electronic Control Unit" is also the name of a song by Peter Gabriel
