Power control system

A power control system for a forestry machine configured to perform a plurality of functions, the power control system comprising:

• an engine control module configured to control an engine speed of an engine of the forestry machine, wherein the engine speed is limited in accordance with a maximum engine speed;
• and
• a pump control module configured to:
• determine whether a first function of a predetermined subset of the plurality of functions of the forestry machine is activated, wherein the predetermined subset of the plurality of functions are functions of one or more selected attachments of the forestry machine;
• determine whether the activated first function is designated as a high pressure function;
• determine that a magnitude of a pressure of a pump that provides flow to the activated first function has increased, wherein the increase of magnitude of the pressure is caused by the activation of the first function;
• determine that the magnitude of the pressure is greater than or equal to a high pressure setpoint;
• and
• upon determining that the first function is activated, the activated first function is a high pressure function, the magnitude of the pressure of the pump that provides flow to the activated first function has increased, and the increase in the pressure is greater than or equal to the high pressure setpoint, output a control signal indicating a request for a power increase,
• wherein the engine control module receives the request for the power increase and is configured to increase the maximum engine speed of the engine in response to the request for the power increase received from the pump control module.
