Engine control in a hybrid Prius
The engine control module manages the gasoline engine’s operation, including functions such as fuel injection and ignition timing. In a Prius, it also works with the hybrid control system to coordinate engine operation with the electric drive. That coordination affects when the engine runs and how it contributes power while driving.
