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.
