Abstract: A position switching device includes a rotating body, a drive unit, and a plurality of position switching rods. The rotating body has, on a surface, a plurality of position switching groove groups each defining a plurality of switching positions and rotates about one shaft as a rotation axis. The drive unit rotationally drives the rotating body in a first rotation direction or a second rotation direction opposite to the first rotation direction. The plurality of position switching rods each has one end engaged with corresponding one of the plurality of the position switching groove groups and the other end engaged with corresponding one of a plurality of position switching mechanisms.

Abstract: A dog clutch control system includes a dog clutch including a first engagement member and a second engagement member, an actuator, a rotational speed detecting unit, an arrival timing predicting unit, and a phase correcting unit. The arrival timing predicting unit predicts an arrival timing at which a rotational speed difference between the first engagement member and the second engagement member is adjusted to a value equal to or less than a predetermined threshold, based on the rotational speeds of the first and second engagement member and a time variation characteristic of the rotational speed difference during a rotational speed adjustment. The phase correcting unit performs a phase correction to bring an engageable timing, which is a timing at which the first engagement member is engageable with the second engagement member after the arrival timing, closer to the arrival timing compared to a case without the phase correction.
