Abstract: A vibration damping device including a support member rotabable about the center of rotation of a rotary element; a restoring force generation member coupled to the support member; an inertial mass body coupled to the support member via the restoring force generation member; and a guided portion and a guide portion provided alternately on one of the restoring force generation member or the inertial mass body. The guide portion guides the guided portion so the restoring force generation member swings along the radial direction of the center of rotation and the inertial mass body swings about the center of rotation when the support member is rotated. A component of a centrifugal force acting on the restoring force generation member is transferred from the guided portion to the guide portion. The restoring force generation member includes two mass bodies facing each other and disposed on sides of the inertial mass body.

Abstract: A shift control device of a vehicle including an internal combustion engine and a multi-speed transmission in series, the shift control device comprises: a control portion providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up of the internal combustion engine toward a post-shift input shaft rotation speed in a neutral state where a release-side engagement device to be released during a downshift of the multi-speed transmission is released, so as to engage an engagement-side engagement device to be engaged after the shift. In the case of a shift pattern having a large internal inertia of the multi-speed transmission, the control portion controls a torque capacity of the engagement-side engagement device to a value greater than zero before starting a torque-up control of the internal combustion engine.

Abstract: Display devices and programs display a guide image on a display mounted on a vehicle so as to be visually recognized such that the guide image is superimposed on a view ahead of the vehicle. The guide image provides guidance about a travel direction of the vehicle that travels on a travel path after leaving a guide branch point. The devices and programs display the guide image in a manner such that a region overlapping a nearby object present on a near side of the travel path on which the vehicle travels is removed from the guide image.

Abstract: In this stator core, the interval in the circumferential direction of the stator core between an outer peripheral surface of an axial end of a slot accommodated portion of a concentric coil and a tooth facing the outer peripheral surface is larger than the interval in the circumferential direction of the stator core between an inner peripheral surface of the axial end and a tooth facing the inner peripheral surface.

Abstract: A torsional vibration damper that damps torsional vibration effectively in a low-speed range. In the torsional vibration damper, a spring holder is formed by apertures of an input element and an output element, and an elastic member is held in the spring holder. A first moveable range of a planetary element extending from an initial position in a drive direction is wider than a second movable range of the planetary element extending from the initial position in a counter direction.

Abstract: A communication terminal is connected to a server and provides movement guidance for a mobile unit based on guidance information delivered from the server. The terminal requests the server for update information for updating area identification information that identifies a section corresponding to an update target area and a section not corresponding to the update target area on a section-by-section basis. The update target area is an area whose terminal-side map information included in the communication terminal is an older version. The terminal updates the area identification information based on the update information transmitted from the server, requests the server for guidance information for providing movement guidance for the mobile unit based on the updated area identification information, and provides the movement guidance for the mobile unit based on the guidance information delivered from the server.

Abstract: Travel assistance devices and programs identify a connecting road present in a driver's field of vision and having driver's visibility lower than a threshold among connecting roads. The connecting roads are roads connecting to a traveling road of a vehicle at a divergence point present around the vehicle. The devices and programs provide guidance informing of presence of an invisible road that is the identified connecting road.
