Vehicle window glass raising/lowering device, vehicle door, and vehicle
A vehicle window glass raising/lowering device includes a drive mechanism, a control unit for controlling the drive mechanism, a camera for capturing an image of a detection line. The camera includes an optical system. The control unit includes a detection means for detecting a blocked state in which the detection line captured in an image by the camera is at least partially blocked by a foreign object, and a pinching prevention means when the blocked state is detected by the detection means during when the window glass is moved by the drive mechanism. The optical system is arranged at a position corresponding to an opening formed on an upper surface of a door trim so that an optical axis of the optical system passes through the opening.
1. A vehicle window moving device, comprising:
a drive mechanism arranged on a vehicle door, the vehicle door comprising a storage portion for housing a window glass and a frame portion provided above the storage portion, the drive mechanism configured to vertically move the window glass relative to the frame portion;
a control unit for controlling the drive mechanism; and
a camera for capturing an image of a detection line provided on a vehicle interior side with respect to the window glass, the detection line being along at least a portion of the frame portion,
wherein the camera comprises an optical system comprising at least one lens and an image pickup device onto which a subject image is focused by the optical system,
wherein the control unit comprises a detection means for detecting a blocked state in which the detection line captured in an image by the camera is at least partially blocked by a foreign object, and a pinching prevention means that causes the drive mechanism to perform a pinch prevention operation for preventing pinching by the window glass when the blocked state is detected by the detection means during when the window glass is moved by the drive mechanism,
wherein the camera is attached to an edge of a hole in an upper surface of a door trim, and
wherein a portion of the optical system is arranged above an opening formed on the upper surface of the door trim attached on a vehicle interior side of the storage portion.
2. The vehicle window moving device according to claim 1 , wherein the optical system of the camera is arranged so that the optical axis is located on a vehicle interior side with respect to an exit slot that exits the window glass from the storage portion.
3. The vehicle window moving device according to claim 1 , further comprising a light source that is provided on the upper surface of the door trim and that emits infrared radiation toward the detection line,
wherein the camera is an infrared camera that captures the infrared radiation emitted from the light source and reflected by the detection line.
4. The vehicle window moving device according to claim 1 , wherein the control unit further comprises a command cancellation means that cancels a command for moving the window glass when the blocked state is detected by the detection means after issuing the command and before starting movement of the window glass.
5. The vehicle window moving device according to claim 1 , wherein the camera is configured to capture the detection line, the detection line provided continuously from an inner circumferential surface of a rear upright portion extending upwards from an end of the storage portion on the rear side in a front-back direction of the vehicle, to a front upright portion extending upwards from the storage portion on a front side with respect to the rear upright portion and to an upper extended portion extending from a top end of the rear upright portion to a top end of the front upright portion.
6. A vehicle door, comprising:
a storage portion for housing a window glass;
a frame portion provided above the storage portion;
a door trim attached on a vehicle interior side of the storage portion;
a drive mechanism that vertically moves the window glass relative to the frame portion;
a control unit for controlling the drive mechanism; and
a camera that is attached to an edge of a hole in an upper surface of the door trim for capturing an image of a detection line provided on an interior of a vehicle, the detection line being along at least a portion of the frame portion,
wherein the camera comprises an optical system comprising at least one lens and an image pickup device onto which a subject image is focused by the optical system, wherein the control unit comprises a detection means for detecting a blocked state in which the detection line captured in an image by the camera is at least partially blocked by a foreign object, and a pinching prevention means that causes the drive mechanism to perform a pinch prevention operation for preventing pinching by the window glass when the blocked state is detected by the detection means during when the window glass is moved by the drive mechanism,
wherein an opening is formed on the upper surface of the door trim, and wherein a portion of the optical system is arranged above the opening formed on the upper surface of the door trim on the vehicle interior side of the storage portion.
7. The vehicle door according to claim 6 , wherein the opening is formed in the door trim on the vehicle interior side with respect to an exit slot that exits the window glass from the storage portion.
8. The vehicle door according to claim 6 , further comprising a light source that is provided on the upper surface of the door trim and that emits infrared radiation toward the detection line,
wherein the camera is an infrared camera that captures the infrared radiation emitted from the light source and reflected by the detection line.
9. The vehicle door according to claim 6 , wherein the control unit further comprises a command cancellation means that cancels a command for moving the window glass when the blocked state is detected by the detection means after issuing the command and before starting movement of the window glass.
10. A vehicle, comprising the vehicle door according to claim 6 .
11. The vehicle door according to claim 6 , wherein the camera is configured to capture the detection line, the detection line provided continuously from an inner circumferential surface of a rear upright portion extending upwards from an end of the storage portion on the rear side in a front-back direction of the vehicle, to a front upright portion extending upwards from the storage portion on a front side with respect to the rear upright portion and to an upper extended portion extending from a top end of the rear upright portion to a top end of the front upright portion.
