Abstract
Embodiments of the subject matter disclosed herein relate to controlling engine operating points and power for full throttle command in an off-highway vehicle, such as a diesel electric haul truck, to increase fuel efficiency. In one example, a system includes an engine and a controller. The controller is configured to determine a target engine horsepower and associated target engine speed, command the engine to operate at a first engine speed above the target engine speed, adjust a load placed on the engine to reach the target engine speed, and command the engine to operate at a second engine speed to reach the target engine horsepower.
