US 12,349,626 B2 · Predictive power boost demand system for an agricultural vehicle

Abstract

A harvesting machine for harvesting a crop and discharging the harvested crop to an offboard container, such as a wagon or a truck, or the ground. The harvesting machine includes a power system to provide power, a crop harvester powered by the power system, and a crop discharging system to discharge crop from an onboard storage container to the offboard location, typically a container. During a harvesting operation, the harvesting machine operates at a nominal maximum power, typically a current power consumption. The nominal maximum power is reduced in anticipation of a predicted power used for discharging the harvested crop from the onboard storage container. The current power consumption for harvesting is adjusted and allocated by the predicted power to make available power for the crop discharging system. Once crop is discharged using the discharging power, the harvesting machine returns to the nominal maximum power.

Dependent claims

A method of controlling work machine power of a work machine during a harvesting operation for harvesting a crop and delivering the harvested crop to an external crop container, wherein the work machine includes an engine, a crop harvester, an onboard crop storage container and a crop discharging system, the method comprising:

monitoring crop harvester power delivered by the engine to operate the crop harvester during the harvesting operation to provide harvested crop;
while monitoring the crop harvester power, determining a discharging power required by the crop discharging system to discharge the harvested crop to the external crop container;
modifying and allocating the crop harvester power based on the determined discharging power;
and
delivering the discharging power to the crop discharging system to discharge the crop from the onboard crop storage container to the external crop container.

2 more elements

A work machine comprising:

a supporting structure;
a harvesting assembly coupled to the supporting structure;
an onboard container coupled to the supporting structure and configured to contain harvested crop harvested by the harvesting assembly;
a crop discharging system, disposed at the onboard container and configured to discharge harvested crop from the onboard container;
an engine configured to provide harvesting power to the harvesting assembly and to provide discharging power to the crop discharging system;
a controller operatively connected to the harvesting assembly and to the discharging system, the controller including a processer and a memory, wherein the memory is configured to store program instructions and the processor is configured to execute the stored program instructions to:
monitor crop harvester power delivered by the engine to operate the crop harvester during the harvesting operation to provide harvested crop;
while monitoring the crop harvester power, determine a discharging power required by the crop discharging system to discharging the harvested crop from the onboard crop container;
modify the crop harvester power based on the determined discharging power;
and
deliver the discharging power to the crop discharging system to discharge the crop from the onboard container.
