Embodiments of an intelligent power allocation system include a ground traction undercarriage controllable to propel a hybrid combine over terrain, a separator device configured to separate grain from other crop material ingested by the hybrid combine, a mechanical powertrain including an internal combustion engine, and an electric drive subsystem containing a rechargeable battery pack and a motor/generator (M/G). A controller architecture is configured to monitor a current separator load placed on the hybrid combine when driving movement of the separator device during active harvesting. The controller architecture further selectively places the intelligent power allocation system in a separator power splitting mode in which the M/G and the internal combustion engine concurrently drive movement of the separator device based, at least in part, on whether the current separator load exceeds an upper load threshold.

A vehicle includes a frame, at least one traction device coupled to the frame for facilitating movement of the vehicle, an implement coupled to the frame and configured to perform a work operation, a gearbox, a hydraulic system having a hydraulic reservoir, and an oil cooling system configured to cool the gearbox and the hydraulic system. The oil cooling system includes first and second circuits for a cooling oil, and a crossover circuit. The first circuit includes the gearbox and a first oil-to-air cooler configured to cool the cooling oil from the gearbox. The second circuit includes the hydraulic reservoir and a second oil-to-air cooler for cooling the cooling oil from the hydraulic reservoir.

Embodiments of an intelligent hybrid powertrain system include an engine, a controller architecture, and an electric drive subsystem having a battery supply and a motor/generator. The controller architecture is configured to: (i) monitor a current state of charge (SoC) of the battery supply when the combine harvester engages in a combine harvest cycle having a tank fill phase and a tank unload phase; (ii) during the tank fill phase, operate the motor/generator to supplement the engine power output and regulate a rate of battery discharge to prevent the current SoC of the battery supply from decreasing below a lower predetermined SoC threshold prior to completion of the tank fill phase; and (iii) during the tank unload phase, operate the motor/generator to charge the battery supply until the current SoC of the battery supply is equal to or greater than a first upper predetermined SoC threshold.

Intelligent hybrid powertrain systems for combine harvesters

A work machine for harvesting crop includes a controller and an engine. The controller is configured to command operation of the engine in accordance with various power curves based on sensed factors associated with the harvested crop. The work machine stores the harvested crop in a tank to be unloaded by an unloading auger which is powered by the engine. Prior to activation of the unloading auger, the controller commands the engine to operate in accordance with a power curve associated with a reduced power level to reserve power for operation of the unloading auger.

Pre-unloading power reduction system and method

A combustion air filtration apparatus for filtering combustion air for an engine is disclosed. The combustion air filtration apparatus comprises a combustion air source and a filter system fluidly coupled to the combustion air source and to the engine to receive combustion air from the combustion air source and to supply filtered combustion air for the engine. The filter system comprises a first combustion air filter, a second combustion air filter flow-parallel to the first combustion air filter, and a flow control system fluidly coupled to the first combustion air filter and the second combustion air filter to direct flow of combustion air selectively between the first combustion air filter and the second combustion air filter.

A cooling system includes a fan, a first fluid circuit, and a second fluid circuit. The first fluid circuit includes a first fluid, a first heat exchanger, a first exchanger bypass, and a first thermostat to selectively control flow of the first fluid between the first heat exchanger and the first exchanger bypass. The second fluid circuit is fluidly independent of the first fluid circuit. The second fluid circuit includes a second fluid separate from the first fluid, a second heat exchanger, a second exchanger bypass, and a second thermostat to selectively control flow of the second fluid between the second heat exchanger and the second exchanger bypass.
