<p>An internal combustion engine is provided having a crankshaft which rotates in an actual crankshaft speed. An accessory drive is driven by the crankshaft and includes an accessory drive component, such as an alternator, which produces a load on the crankshaft. A speed sensor senses an engine speed associated with the actual crankshaft speed and produces a speed signal. A controller sends a control signal to the accessory drive component in response to the speed signal to change the load of the accessory drive component and maintain the actual crankshaft speed at a target crankshaft speed. If sufficient control of the engine speed is not possible by changing the load of the accessory drive component alone, the throttle may also be changed to overcome the load fluctuations of the engine and assist the control provided by the accessory drive component.</p> |
