	On-Board Vehicle Power (OBVP)
	Speed Control System
	The system features an advanced adaptive speed controller. To optimally use the system, especially from the perspective of fuel economy, a speed control is necessary to match the most efficient speed of the engine to the load supplied by the power electronics. The adaptive speed controller uses a stepper motor to move the throttle when a current transducer monitored by the speed controller senses a change in the load. The speed controller electronics are mounted in a small box under the driver seat. A speed controller interface and display box is placed next to the ignition. This interface allows the driver to turn the system on or off and monitor the system status with LED's. The speed controller provides for load sensing and adaptive control, so that the engine speed is continuously adjusted to optimally power the load. Because the alternator provides DC current, it is NOT necessary to run the engine at a fixed RPM determined by the AC frequency required by the load. Thus wet stacking under light load conditions, a perennial maintenance problem with conventional diesel motor/generator sets, is eliminated.
