Abstract
A control device for a power transmission mechanism includes a controller. The power transmission mechanism includes an engagement mechanism and an operation mechanism including a movable member and a guide member. The guide member includes a plurality of guide areas being configured to move relative to the movable member to guide the movable member to an engaging position or to a disengaging position. The controller is configured to switch, when determining that a predetermined condition related to traveling of the vehicle is satisfied, a contact guide area that is in contact with the movable member to guide the movable member to the engaging position or to the disengaging position, from a first guide area to a second guide area that are included in the plurality of guide areas.
Claims13
A control device for a power transmission mechanism, the power transmission mechanism including:
- an engagement mechanism configured to be switched between an engaged state in which a torque for causing a vehicle to travel is transmitted and a disengaged state in which the torque is interrupted;
- and
- an operation mechanism configured to switch the engagement mechanism between the engaged state and the disengaged state, the operation mechanism including,
- a movable member coupled to the engagement mechanism, and configured to move to an engaging position where the engagement mechanism is set to the engaged state, and to move to a disengaging position where the engagement mechanism is set to the disengaged state, and
- a guide member provided in contact with the movable member and configured to move the movable member to the engaging position or to the disengaging position, the guide member including a plurality of guide areas provided in a continuous manner, each of the guide areas being configured to move relative to the movable member to guide the movable member to the engaging position or to the disengaging position,
- the control device comprising a controller configured to control the operation mechanism, the controller being configured to
- determine whether a predetermined condition related to traveling of the vehicle is satisfied, the predetermined condition including a condition that a vehicle speed is lower than a predetermined vehicle speed, and
- switch, when determining that the predetermined condition is satisfied, a contact guide area that is in contact with the movable member to guide the movable member to the engaging position or to the disengaging position, from a first guide area that is included in the plurality of guide areas and that has been in contact with the movable member to a second guide area that is included in the plurality of guide areas.

- an engagement mechanism configured to be switched between an engaged state in which a torque for causing a vehicle to travel is transmitted and a disengaged state in which the torque is interrupted;
- and
- an operation mechanism configured to switch the engagement mechanism between the engaged state and the disengaged state, the operation mechanism including,
- a movable member coupled to the engagement mechanism, and configured to move to an engaging position where the engagement mechanism is set to the engaged state, and to move to a disengaging position where the engagement mechanism is set to the disengaged state, and
- a guide member provided in contact with the movable member and configured to move the movable member to the engaging position or to the disengaging position, the guide member including a plurality of guide areas provided in a continuous manner, each of the guide areas being configured to move relative to the movable member to guide the movable member to the engaging position or to the disengaging position,
- the control device comprising a controller configured to control the operation mechanism, the controller being configured to
- determine whether a predetermined condition related to traveling of the vehicle is satisfied, the predetermined condition including a request to switch an untravelable state to a travelable state, and
- switch, when determining that the predetermined condition is satisfied, a contact guide area that is in contact with the movable member to guide the movable member to the engaging position or to the disengaging position, from a first guide area that is included in the plurality of guide areas and that has been in contact with the movable member to a second guide area that is included in the plurality of guide areas.
