Electronic Control Unit (ECU)

An ECU is any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle. Some modern vehicles have up to 80 ECUS and the embedded software in ECUs continues to increase in line count, complexity, and sophistication. Some ECU examples are: engine control module (ECM), powertrain control module (PCM), transmission control module (TCM), and so many more.
