Abstract

A motor vehicle is disclosed having a door that is attached to the motor vehicle by a hinge mechanism providing both full swing opening of the door and full scissor opening of the door. The motor vehicle includes an apparatus to assist with the selection of a preferred mode of door opening based upon an assessment of the surroundings in which the motor vehicle 1 rests. The assessment of the surroundings and selection of the preferred mode of door opening is carried out by an electronic controller based upon information received from a sensing apparatus.

a sensing apparatus to provide information to the electronic controller indicative of whether there are any obstructions to the side of the motor vehicle that would interfere with swing opening of the door and whether there are any overhead obstructions that would interfere with scissor opening of the door, wherein, in response to an indication from the user of the motor vehicle that door opening is required, the electronic controller is arranged to use the information provided from the sensing apparatus to select a preferred mode of door opening; and

wherein the hinge mechanism comprises a plurality of connected hinge members facilitating door opening in the swing mode where the door is rotatable about a first axis between closed and fully swung open positions and the scissor mode where the door is rotatable about a second axis arranged substantially perpendicular to the first axis between the closed position and a scissor open position, wherein the plurality of hinge members comprises first, second, third and fourth hinge members, the first hinge member is used to attach the hinge mechanism to part of the body structure of the motor vehicle, the first hinge member and the third hinge member form a first pair of hinge members, the third and fourth hinge members form a second pair of hinge members and the fourth hinge member is used to attach the hinge mechanism to the door, and wherein the second hinge member is pivotally connected to the first hinge member for rotation about the first axis and is selectively latchable to the first hinge member and the fourth hinge member to control the opening mode of the door.

2. The vehicle as claimed in claim 1, wherein if the information from the sensing apparatus indicates that there is sufficient space for the door to be swung open sufficiently to permit egress from the vehicle then the swing open mode of door opening is selected by the electronic controller.

3. The vehicle as claimed in claim 1, wherein the apparatus further comprises one or more user feedback devices connected to the electronic controller and selecting a preferred mode of door opening comprises providing feedback to the vehicle user using the one or more feedback devices of the mode of door opening that has been selected by the electronic controller as the preferred mode of door opening.

4. The vehicle as claimed in claim 1, wherein the hinge mechanism further includes at least two latching mechanisms controlled by the electronic controller and selecting the preferred mode of door opening includes using the electronic controller to operate the latching mechanisms to facilitate the preferred mode of door opening while inhibiting the other mode of door opening.

5. The vehicle as claimed in claim 1, wherein the hinge mechanism further includes powered swing and scissor door actuation mechanisms controlled by the electronic controller and selecting the preferred mode of door opening includes using the electronic controller to operate at least one of the door actuation mechanisms to produce the preferred mode of door opening.

6. A hinge mechanism connecting a door to a body structure of a motor vehicle, comprising:

a plurality of connected hinge members facilitating door opening in a swing mode where the door is rotatable about a first axis between closed and fully swung open positions and a scissor mode where the door is rotatable about a second axis arranged substantially perpendicular to the first axis between the closed position and a scissor open position, wherein the plurality of hinge members comprises first, second, third and fourth hinge members, the first hinge member is used to attach the hinge mechanism to part of the body structure of the motor vehicle, the first hinge member and the third hinge member form a first pair of hinge members, the third and fourth hinge members form a second pair of hinge members and the fourth hinge member is used to attach the hinge mechanism to the door, and wherein the second hinge member is pivotally connected to the first hinge member for rotation about the first axis and is selectively latchable to the first hinge member and the fourth hinge member to control the opening mode of the door.

7. The hinge mechanism as claimed in claim 6, wherein the first axis is a substantially vertically arranged axis to facilitate the swing mode of door opening and the second axis is a substantially horizontally arranged axis to facilitate the scissor mode of door opening.

8. The hinge mechanism as claimed in claim 6, wherein to facilitate the swing mode of door opening the second hinge member is not latched to the first hinge member and is latched to the fourth hinge member so as to hold the second third and fourth hinge members together and to facilitate the scissor mode of door opening the second hinge member is latched to the first hinge member and is not latched to the fourth hinge member.

9. The hinge mechanism as claimed in claim 6, wherein the hinge mechanism for at least one of the two modes of door opening also facilitates limited movement of the door away from the surrounding body structure about an axis of rotation that is different to the axis of rotation used to subsequently open the door, and wherein the hinge mechanism further comprises a swing rotation stop to provide a predefined limited rotation of the third hinge member about the first axis when the second hinge member is latched to the first hinge member but not to the fourth hinge member to provide the limited movement of the door away from the surrounding body structure prior to full scissor opening of the door.

10. The hinge mechanism as claimed in claim 8, wherein the hinge mechanism further comprises a first latching mechanism to selectively latch the second hinge member to the first hinge member and a second latching mechanism to selectively latch the second hinge member to the fourth hinge member, and wherein the first and second latching mechanisms are electronically controllable latching mechanisms.

11. The hinge mechanism as claimed in claim 9, wherein the second hinge member includes a scissor rotation stop to prevent rotation of the fourth hinge member relative to the third hinge member about the second axis before the limited rotation of the third hinge member about the first axis provided by the swing rotation stop is exhausted.

12. The hinge mechanism as claimed in claim 6, wherein the hinge mechanism comprises first, second, third and fourth hinge members wherein the first hinge member is the hinge member used to attach the hinge mechanism to the body structure, the fourth hinge member is the hinge member used to attach the hinge mechanism to the door, the third and fourth hinge member form the first pair of hinge members, the second and third hinge members form the second pair of hinge members and the second hinge member is pivotally connected to the first hinge member for limited rotation about a third substantially vertical axis spaced away from the first and second axes.

13. The hinge mechanism as claimed in claim 12, wherein the fourth hinge member rotates relative to the third hinge member about the first pivot axis to facilitate the swing mode of door opening and the third hinge member rotates relative to the second hinge member about the second axis to facilitate the scissor mode of door opening.

14. The hinge mechanism as claimed in claim 12, wherein the hinge mechanism includes a first latching mechanism to selectively latch the first and third hinge members together and a second latching mechanism to selectively latch the third and fourth hinge members together, and wherein the first and second latching mechanisms are electronically controllable latching mechanisms.

15. The hinge mechanism as claimed in claim 14, wherein the hinge mechanism for at least one of the two modes of door opening also facilitates limited movement of the door away from the surrounding body structure about an axis of rotation that is different to the axis of rotation used to subsequently open the door, and wherein the hinge mechanism includes a swing rotation stop to allow a limited rotation of the second hinge member relative to the first hinge member about the third axis when the first latching mechanism is unlatched to provide the limited movement of the door away from the surrounding body structure prior to scissor opening of the door.

16.
