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.

When the remaining charge level of the battery decreases to a predetermined first determination value or less, the engine rotational speed increase control unit increases the target lower limit rotational speed of the engine or of the motor to the target lower limit rotational speed so that the operating point of the engine falls within a predetermined engine torque stable region. Then, in a state where the operating point of the engine is within the engine torque stable region, the charge control unit controls the negative torque of the electric motor so that the actual charge level by the electric motor becomes a preset target charge level. The battery can thus be recovered from an insufficient charge level.

In this engine control device for controlling an engine with a turbocharger, a rotation speed increase mode includes at least one stage of fuel injection in one combustion cycle of the engine, a high-idle mode includes at least two stages of fuel injection in one combustion cycle of the engine, and a high-idle mode execution unit is configured to retard the timing of the second stage fuel injection in one combustion cycle of the engine in the high-idle mode, relative to the timing of the first stage fuel injection in one combustion cycle of the engine in the rotation speed increase mode.

A harvesting machine is provided 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.

In an approach to active engine idle control, an apparatus comprises: an accelerator module interface; an engine control module (ECM) interface; a computer readable storage media; and a controller. The controller is configured to: determine an engine speed target for a vehicle engine in revolutions per minute (RPM) based on an electrical load on the vehicle; determine a voltage curve for one or more position sensors of an accelerator module in the vehicle; determine a voltage target for the ECM for each position sensor of the one or more position sensors; and responsive to a first signal that the apparatus is engaged and a second signal that the vehicle is stopped, set an input voltage to the ECM at the voltage target for each of the one or more position sensors.

Methods and systems for operating a vehicle powertrain that includes a power take-off are presented. In one non-limiting example, engine speed may be adjusted to increase engine efficiency during conditions when the engine is operating at idle conditions for longer than a threshold amount of time so that fuel consumption and wear may be reduced.
