Abstract
A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; and an action position detection unit detecting an action position of the swing door. The braking control unit sets a strong opening prevention boundary on a closing direction side from a fully open position as a mechanical opening action limit of the swing door and applies a braking force to the swing door that opens on an opening direction side from the strong opening prevention boundary.
Claims10
A vehicle door device comprising:
- a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device;
- and
- an action position detection unit detecting an action position of the swing door, wherein
- the swing door is opened/closed between a fully closed position and a fully open position in an opening/closing action stroke of the swing door, the swing door moving in an opening direction from the fully closed position to the fully open position, and moving in a closing direction from the fully open position to the fully closed position,
- the braking control unit sets a strong opening prevention boundary in the closing direction from the fully open position as a mechanical opening action limit of the swing door and applies a braking force to the swing door that opens in the opening direction from the strong opening prevention boundary,
- a full latch position where the swing door is restrained with respect to a vehicle body based on an engagement force of a latch mechanism provided in the swing door serves as the fully closed position of the swing door,
- the braking control unit sets a braking boundary in the opening direction from a half latch position where the latch mechanism generates the engagement force and does not apply the braking force when an action position of the swing door is between the braking boundary and the fully closed position, and
- the braking control unit sets the braking boundary in the opening direction from an action position of the swing door where a distal end position of a rear view member provided in a front end portion of the swing door and a rear end position of the swing door are reversed in a vehicle width direction.

- and
- an action position detection unit detecting an action position of the swing door, wherein
- the swing door is opened/closed between a fully closed position and a fully open position in an opening/closing action stroke of the swing door, the swing door moving in an opening direction from the fully closed position to the fully open position, and moving in a closing direction from the fully open position to the fully closed position,
- a full latch position where the swing door is restrained with respect to a vehicle body based on an engagement force of a latch mechanism provided in the swing door serves as the fully closed position,
- the braking control unit sets a braking boundary in the opening direction from a half latch position where the latch mechanism generates the engagement force and does not apply the braking force when an action position of the swing door is between the braking boundary and the fully closed position, and
- the braking control unit sets the braking boundary on the opening direction from an action position of the swing door where a distal end position of a rear view member provided in a front end portion of the swing door and a rear end position of the swing door are reversed in a vehicle width direction.
