ABSTRACT:
An apparatus for controlling an idling speed of an internal combustion engine is disclosed. The apparatus includes an electric machine operatively coupled to the internal combustion engine for applying a braking torque to the internal combustion engine to reduce the idling speed and for applying a driving torque to the internal combustion engine to increase the idling speed. It also includes a controller for controlling the electric machine. The controller is responsive to a load change to control the electric machine to apply one of a braking torque and a driving torque to the internal combustion engine to substantially maintain the idling speed at a predefined level.
