Abstract
A system includes a vehicle controller which includes a memory configured to store instructions and one or more processors. The vehicle controller is configured to set a fuel efficient operation mode. The fuel efficient operation mode includes setting a commanded engine speed to a nominal engine speed located within a range of optimal fuel efficiency engine speeds of a brake specific fuel consumption map. The fuel efficient operation mode also includes instructing an engine to operate at the commanded engine speed. The fuel efficient operation mode also includes determining a monitored engine speed. The fuel efficient operation mode also includes adjusting a commanded pump displacement in response to the monitored engine speed exceeding the range of optimal fuel efficiency engine speeds. The fuel efficient operation mode also includes instructing a hydraulic pump to operate at the commanded pump displacement.
