A planetary gear mechanism is desired in which pinion gears can be inserted between support portions on both sides in the axial direction of the pinion gears after the support portions on both sides in the axial direction of the pinion gears are coupled together. In this planetary gear mechanism, a coupling inner portion of a carrier coupling portion is located between a first sun gear and a second sun gear in the axial direction, and a carrier and the carrier coupling portion are formed so that each pinion gears can be inserted between a first shaft support portion and a second shaft support portion in the axial direction from the outside in the radial direction.

An electronic control unit stores a vehicle load at the time when the vehicle is switched into an ignition off state, stops operation of an electric oil pump when the vehicle load is small, and operates the electric oil pump when the vehicle load is large. Thus, a decrease in service life due to an increase in the number of times of the start of the electric oil pump is suppressed, and, when it is estimated that the vehicle load is large, the response of the start of a vehicle, which makes a driver experience a feeling of strangeness, is improved by starting the electric oil pump together with switching the vehicle into an ignition on state.

Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

Methods and systems for a clutch assembly in an electric drive axle of a vehicle are provided. In one example, a clutch assembly in a gear train is provided that includes a locking clutch. The locking clutch includes a gear including a plurality of teeth having at least one tooth with a tapered end, an indexing shaft rotationally connected to an output shaft, a shift collar mounted on the indexing shaft, configured to translate on the indexing shaft into an engaged and disengaged configuration, and including a plurality of teeth on a face, where at least one tooth in the plurality of teeth in the shift collar includes a tapered end, and an indexing mechanism coupled to the shift collar and the indexing shaft and configured to accommodate for indexing between the indexing shaft and the shift collar during shift collar engagement.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

When evacuation travel is performed using only a drive power from one drive power source of an engine and a rotary machine, a drive power distribution device is prohibited from switching to a four-wheel-drive state and thus evacuation travel is performed in a two-wheel-drive state in which a loss in a power transmission device is relatively small. Accordingly, in a four-wheel-drive vehicle, it is possible to increase an evacuation-travelable distance when evacuation travel is performed using only the drive power from one drive power source of the engine and the rotary machine.

In a hybrid vehicle, when a required driving force is equal to or smaller than a first upper limit driving force, a control device sets a target driving force to the required driving force. When the required driving force is larger than the first upper limit driving force, the control device sets a target compensation power of a power storage device, based on a difference between the required driving force and the first upper limit driving force. The control device sets a second upper limit driving force of a driveshaft when an upper limit power is output from an engine and the power storage device is charged or discharged with a power based on the target compensation power. The control device sets a target driving force to the smaller between the required driving force and the second upper limit driving force. This configuration suppresses deterioration of the driver's drive feeling.
