Fuel efficient operation mode

A method comprising:

• setting, via a controller having a memory and a processor, 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;
• instructing, via the controller, an engine to operate at the commanded engine speed;
• determining, via the controller, a monitored engine speed;
• adjusting, via the controller, a commanded pump displacement in response to the monitored engine speed exceeding the range of optimal fuel efficiency engine speeds;
• and
• instructing, via the controller, a hydraulic pump to operate at the commanded pump displacement.

A work vehicle, comprising:

• a hydrostatic drive, comprising:
• a motor;
• a pump configured to provide hydraulic fluid to the motor;
• an engine configured to power the pump;
• and
• a vehicle controller, wherein the vehicle controller comprises:
• a memory configured to store instructions;
• and
• a one or more processors configured to execute the instructions, wherein the vehicle controller is configured to set a fuel efficient operation mode, wherein the fuel efficient operation mode comprises:
• 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;
• instructing the engine to operate at the commanded engine speed;
• determining a monitored engine speed;
• adjusting a commanded pump displacement in response to the monitored engine speed exceeding the range of optimal fuel efficiency engine speeds;
• and
• instructing a hydraulic pump to operate at the commanded pump displacement.
