摘要： An overload prevention system and method for an electric circuit having a plurality of components is disclosed, where each component has a set of pre-computed parameters. For each component, monitored parameters are observed; a limited value is computed using the pre-computed and monitored parameters; and it is determined if the limited value reached a limit. If the limited value reaches the limit; the system limits one of the monitored parameters. Pre-computed parameters can include time constant and rated current; monitored parameters can include current; and limited value can be component temperature. A time constant, rated current and rated temperature can be pre-computed such that the temperature stays at or below the rated temperature when the current is substantially equal to the rated current. Per unit values can also be used such that per unit temperature stays at or below unity when per unit current is substantially equal to unity.

摘要： An energy management control module is configured for communication with the vehicle controller. The energy management control module is configured to generate generator command data for the generator in a power command mode. In one embodiment, the energy management control module supports a first mode and a second mode. A first mode comprises the power command mode and a stored power extraction mode that are mutually exclusive modes for any sampling interval. In the power command mode of the first mode, the energy management controller is configured to generate generator command data for the generator based on a commanded motor torque and an energy storage power command (e.g., SOC command data) if the primary rotational energy of the internal combustion engine meets or exceeds the total vehicle load for a sampling interval.

摘要： A work machine includes an engine for driving a primary working unit. At least one hydraulically powered auxiliary working unit is powered by a hydraulic pump. The engine and an electric motor both provide power to the hydraulic pump via a planetary gear set which sums the power inputs from the engine and the electric motor. The pump speed of the hydraulic pump is thereby decoupled from the engine speed of the engine.

摘要： A power shift transmission includes an input shaft and a gear housing including a gear assembly disposed therein. The gear assembly is driven by the input shaft. The transmission also includes an output shaft rotated by the gear assembly. The transmission also includes an auxiliary shaft extending through a portion of the gear housing. The auxiliary shaft is rotated by an internal combustion engine. The transmission also includes a clutch assembly movable from a disengaged position to an engaged position. The clutch assembly includes a first clutch portion coupled to the input shaft and a second clutch portion coupled to the auxiliary shaft. The second clutch portion transmits rotational force to the first clutch portion only with the clutch assembly in the engaged position. The transmission also includes an electric motor including an electric motor shaft in geared relationship with the first clutch portion.

摘要： The available power surge capacity of a battery is detected. The available steady state regeneration energy capacity of the battery is also detected. The available battery generation power, available from an electric motor, is detected as well. The generation power available from the electric motor is applied to regenerate (or recharge) the battery based upon the available power surge capacity, and the available steady state capacity of the battery.

摘要： A driven wheel unit includes an electric motor coupled to a two-speed, three stage planetary drive assembly and has a width dimensioned for traveling between rows of crop. A wheel hub is supported on an outer surface of a fixed housing by large diameter wheel bearings surrounding both a motor-containing cavity and an adjacent cavity containing first and second planetary stages. Nested radially and surrounding the two planetary stages are two SAHR disc clutches including pistons engaging inner and outer surfaces of a compact piston guide member. The third stage planet carrier defines a cap and is fixed to an axially outer end of the wheel hub. A third stage ring gear has an outside diameter approximately equal to that of the wheel bearings and has an inside diameter fixed to the housing by a planar, annular wheel bearing retainer plate that is fixed to an end of the housing.

摘要： A control system for a work vehicle includes a power source with an engine and at least one motor configured to generate power; a transmission including a plurality of clutches configured for selective engagement to transfer the power to drive an output shaft of a powertrain of the work vehicle; and a controller coupled to the power source and the transmission. The controller has a processor and memory architecture configured to: initiate a transition for the transmission between a first transmission mode and a second transmission mode at a first shift point associated with an engine throttle shift function; determine a current engine speed; and generate and execute an engine speed command for the engine such that a commanded engine speed is a function of the current engine speed in accordance with the engine throttle shift function upon the transition of the transmission at the first shift point.
