Abstract
A control device includes: an engagement mechanism having a first engagement element and a second engagement element; and an actuator that generates a thrust that brings the first engagement element and the second engagement element close to each other when the engagement mechanism is engaged. The control device performs engagement with the thrust of the actuator when a differential rotation speed of the engagement mechanism is less than a predetermined value. In the control device, a parameter indicating an operating state of the actuator is detected, a target differential rotation speed is calculated in accordance with a value of the detected parameter, and the differential rotation speed is controlled to the calculated target differential rotation speed.
Claims8
A control device for an engagement mechanism, the control device comprising:
- an engagement mechanism having a first engagement element and a second engagement element that are rotatable relative to each other;
- an actuator that generates a thrust that brings the first engagement element and the second engagement element close to each other when the engagement mechanism is engaged;
- and
- a controller for controlling the engagement mechanism, the control device being configured to engage the first engagement element and the second engagement element with the thrust of the actuator when a differential rotation speed that is a difference between a rotation speed of the first engagement element and a rotation speed of the second engagement element is less than a predetermined value set in advance,
- wherein the controller is configured to, when the first engagement element and the second engagement element are engaged, detect a parameter indicating an operating state including the thrust of the actuator, calculate a target differential rotation speed for engagement of the first engagement element and the second engagement element in accordance with a value of the detected parameter, and control the differential rotation speed to the calculated target differential rotation speed.
