Abstract

Provided is a control device performing upshifting engagement control where engagement pressure of a second engagement device is gradually increased, and disengagement control where a disengagement force to disengage a first engagement device acts on a meshing portion of the first engagement device. The control device gradually increases engagement pressure of the second engagement device toward target engagement pressure at which transmission torque capacity of the second engagement device reaches a magnitude determined based on input torque from a drive power source to an input member, and changes engagement pressure of the second engagement device set at or after a time when the engagement pressure of the second engagement device reaches set engagement pressure lower than the target engagement pressure, smaller than a change rate of the engagement pressure of the second engagement device set before reaching the set pressure, and thereafter starts the disengagement control.

Abstract

A conveyer equipped with rotating discs rotatable around axes thereof relative to a mounting base. Each of the rotating discs has grooves in which rectangular wires are receivable. When an upstream and a downstream one of the rotating disc are arranged in a given angular relation to each other, one of the grooves of the upstream rotating disc is aligned with that of the downstream rotating disc to pass the rectangular wire from the upstream rotating disc to the downstream rotating disc. Upon such passing of the rectangular wire, the grooves of the upstream and downstream rotating discs hold or clamp all side surfaces of the rectangular wire, thereby ensuring the stability in retaining the rectangular wire when passed from one to another of the rotating discs, which enables the conveyer to carry the rectangular wires at high speeds.

Abstract

When starting a skip downshift, a controller for an automatic transmission disengages two or more engagement elements that are in an engaged state. The disengaging two or more engagement elements includes setting a first engagement element, which is one of the two or more engagement elements that are disengaged and is used to form an intermediate gear stage having a lower transmission ratio than a post-shifting gear stage, to an engagement preparation state that maintains a state immediately before the engaged state. Subsequently, the controller engages a second engagement element, which is used to form both the intermediate gear stage and the post-shifting gear stage, and temporarily increases engagement pressure of the first engagement element. The controller disengages the first engagement element and engages a third engagement element, which is used to form the post-shifting gear stage, to form the post-shifting gear stage.

Abstract

In an element of a power transfer belt to be wound around a primary pulley and a secondary pulley of a continuously variable transmission to transfer torque, the distance from a boundary line between a surface positioned on the outer peripheral side of the power transfer belt with respect to a rocking edge portion and the rocking edge portion to a saddle surface is determined from the slip amount due to micro slip which is relative slipping between the element and the primary pulley caused when the primary pulley pushes out the power transfer belt toward the secondary pulley, and the angular speed of the element and the angular speed of a ring in a range in which the power transfer belt is wound around the secondary pulley.

Abstract

Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a vehicle by an imaging device having a start point of a driver's line of sight and an optical axis corresponding to a driver's line-of-sight direction. The devices and programs identify, based on the captured image and map information of an area around the vehicle, a location where a connecting road is present in the captured image. The connecting road is a road connecting to a traveling road of the vehicle at a divergence point present around the vehicle. The devices and programs determine driver's visibility of the connecting road based on a positional relationship between the location of the connecting road and a location of an obstacle present around the vehicle in the captured image and output a result of the determination.
