摘要： A power transmission apparatus includes an oil pump disposed between a hydraulic controller and a strainer. The oil pump includes a rotor (3) and a housing provided with a rotor chamber housing the rotor (3). Rotation of the rotor (3) causes oil to be sucked into an oil chamber (c1) defined by the rotor (3), and the oil is pressurized and discharged therefrom. The housing is provided with a first oil passage (71) through which oil sucked from a reservoir through the strainer flows toward the oil chamber, and a second oil passage (72) through which oil refluxed from the hydraulic controller flows toward the oil chamber. The second oil passage (72) includes a curved oil passage curved along the rotor (3) and is disposed such that the oil refluxed from the hydraulic controller flows in a rotation direction of the rotor (3) through the curved oil passage.

摘要： Superimposed-image display devices and programs superimpose an image on a surrounding environment in front of a vehicle so that the image can be visually identified. The image includes at least one of a first guidance image that prompts a driver to change driving operation and a second guidance image that does not prompt a driver to change driving operation. The second guidance image is displayed in a display mode in which the second guidance image more harmonizes in at least one of a location, brightness, and color with the surrounding environment than the first guidance image, the surrounding environment being a superimposition target.

摘要： A vehicle drive device includes a control portion that is allowed to execute a control mode that controls multiple hydraulic elements to cause a vehicle in a stop state of an engine to start moving. The control mode starts controlling part of the multiple hydraulic elements before the engine is started, by using oil pressure accumulated in an accumulator (S8). The control mode starts controlling the rest of the multiple hydraulic elements by using oil pressure that is provided after the engine is started (S16).

摘要： A vibration damping apparatus includes a support member configured to rotate together with a rotational element, a restoration force generating member coupled to the support member so as to transmit and receive a torque with the support member, an inertial mass coupled to the support member via the restoration force generating member, a first guide surface provided on the restoration force generating member, a second guide surface provided on the inertial mass, and a coupling member having first and second rolling portions. The first and second guide surfaces are formed so that the first rolling portion rolls along the first guide surface and the second rolling portion rolls along the second guide surface along with rotation of the support member to cause the restoration force generating member to swing relative to a rotation center of the rotational element along a radial direction of the support member and cause the inertial mass to swing about the rotation center.

摘要： A control apparatus for a vehicle includes a vehicle driving control portion configured to permit reverse driving of the vehicle in a reverse direction while the automatic transmission is placed in a forward-drive low-speed gear position, with the motor/generator being operated in a negative direction to generate a negative torque, and a transmission shifting control portion configured to implement a control for promotion to establish the forward-drive low-speed gear position, when switching from forward driving of the vehicle to its reverse driving of the vehicle is required in the process of a shifting action of the automatic transmission to the forward-drive low-speed gear position. The transmission shifting control portion implements the control for promotion to establish the forward-drive low-speed gear position, according to a state of control of the engaging-side coupling device to be brought into its engaged state for establishing the forward-drive low-speed gear position.
