A server includes a communicator and a processor. The communicator is configured to receive a reservation request signal requesting a reservation to use a charging station by an electrified vehicle. The reservation request signal includes information indicating that balancing power control is requested, when the electrified vehicle wants to perform the balancing power control. The processor is configured to set, based on the reservation request signal, a reservation time period during which the electrified vehicle uses the charging station. The processor is configured to set the reservation time period to a longer period when the reservation request signal includes the information indicating that the balancing power control is requested than when the reservation request signal does not include the information indicating that the balancing power control is requested.

A butt position detecting method for a weld joint, when an arrangement direction of a first member and a second member is defined as a first direction, and a direction that is perpendicular to the first direction is defined as a second direction, the first member has a corner portion and a chamfer portion, and a two-dimensional displacement sensor is arranged at a position offset from the butt portion toward the first member side in the first direction, and such that an angle &#x3b8;s at which the second direction and an optical axis direction of irradiation light of the two-dimensional displacement sensor intersect with each other and an angle &#x3b8;a at which the second direction and a formation direction of the chamfer portion of the first member intersect with each other satisfy a condition expression: 0&#xb0;&#x3c;&#x3b8;s&#x3c;&#x3b8;a.

A movable sleeve of a second clutch is provided between a cylindrical ring gear and a cylindrical shaft of a differential case of a differential gear unit. In a disconnect mode in which a propeller shaft is disconnected from rear wheels, the cylindrical ring gear is disconnected from the differential case by the movable sleeve of the second clutch. Thus, in the disconnect mode, a fully differential state of the differential gear unit is prevented.

Auxiliary drive wheel-side differential unit for four-wheel drive vehicle

A control apparatus for a vehicular 4-wheel drive system provided with: primary drive wheels to which a drive force is transmitted from a drive power source; auxiliary drive wheels to which the drive force is selectively transmitted; a first clutch configured to selectively place a first power transmitting path in a power transmitting state and a power cutoff state; and a second clutch disposed in a second power transmitting path to selectively place the second power transmitting path in a power transmitting state and a power cutoff state. The first and second clutches are placed in fully released states to establish a 2-wheel drive mode. The control apparatus includes a first-clutch control portion configured to bring the first clutch into a partially engaged state when a predetermined condition in which the vehicular 4-wheel drive system generates or is considered to generate a noise is satisfied in the 2-wheel drive mode.

Control apparatus for a vehicular 4-wheel drive system

A disconnect mechanism is configured to disconnect a predetermined rotating element from an engine and an auxiliary drive wheels while the vehicle is traveling in a two-wheel drive mode. The predetermined rotating element is configured to transmit power to the auxiliary drive wheels while the vehicle is traveling in a four-wheel drive mode. An electronic control unit is configured to: execute shift control when a shift condition of an automatic transmission is satisfied; selectively engage or release the disconnect mechanism based on a traveling state of the vehicle and a driver's predetermined operation; and control at least one of the automatic transmission or the disconnect mechanism such that a shift period based on the shift condition of the automatic transmission and an engagement-release period of the disconnect mechanism at least partially overlap with each other.

Control system for four-wheel drive vehicle

The rotation of a first rotating element is shifted in speed by a speed shift device, and is transmitted to a second rotating element or a third rotating element of a differential device via a first clutch or a second clutch. In this manner, the torque of right and left driving wheels can be controlled. Furthermore, in conjunction with limitation of the differential motion, the amount of torque transmitted to a fourth rotating element is eliminated by allowing the speed shift device to freely rotate, and the accumulated amount of sliding of friction engagement elements at the time of differential motion limitation can be reduced by completely engaging the first clutch and the second clutch without allowing them to slide. Thus, the differential motion limitation control can be realized without a need to increase the size of the first clutch and the second clutch.

Vehicular drive force distribution device

A vehicle planetary gear device includes a ring gear, a sun gear, and a carrier, and pinions housed in the carrier. A penetration hole formed in a hollow cylindrical portion of the carrier has two inner wall surfaces that face an outer peripheral surface of a pinion. One of the inner wall surfaces has a curvature radius larger than the radius of the pinion, and has a curvature center that is apart from the radius center of the pinion gear. The pinion is disposed with respect to the carrier with a predetermined space formed between the one of the inner wall surfaces and the outer peripheral surface of the pinion, and thereby slides along a radial direction of the carrier.
