Abstract

A vehicle window glass lifting device includes a drive mechanism arranged on a vehicle door to vertically move a window glass, a control unit for controlling the drive mechanism, and a camera for capturing an image of a detection line provided along at least a part of an outer edge of the window glass in a state that the door and the window glass are closed. The control unit includes a detection means for detecting first and second blocked states in each of which the first and second detection lines are each blocked by the foreign object, and a crime prevention control means that determines that the foreign object intrudes from the vehicle exterior to a vehicle interior and conducts a crime prevention operation to a crime prevention when a condition that the second blocked state is detected by the detection means without detecting the first blocked state is satisfied.

Claims

1. A vehicle window glass lifting device, comprising:

a drive mechanism arranged on a vehicle door to vertically move a window glass;

a control unit for controlling the drive mechanism; and

a camera for capturing an image of a detection line provided along at least a part of an outer edge of the window glass in a state that the door and the window glass are closed,

wherein the detection line comprises at least a first detection line, and a second detection line provided on a vehicle exterior side of the first detection line,

wherein the control unit comprises a detection means for detecting a first blocked state in which at least a part of the first detection line captured as the image by the camera is blocked by a foreign object and a second blocked state in which at least a part of the second detection line captured as the image by the camera is blocked by the foreign object, and a crime prevention control means that determines that the foreign object intrudes from a vehicle exterior to a vehicle interior and conducts a crime prevention operation to a crime prevention when a condition that the second blocked state is detected by the detection means without detecting the first blocked state is satisfied.

2. The vehicle window glass lifting device according to claim 1, wherein the crime prevention control means is configured to determine that the foreign object intrudes from the vehicle exterior to the vehicle interior and conducts the crime prevention operation when a condition that the second blocked state is detected by the detection means without detecting the first blocked state and thereafter the first blocked state is detected by the detection means while keeping the second blocked state is satisfied.

3. The vehicle window glass lifting device according to claim 2, wherein the crime prevention operation comprises an operation to lift the window glass automatically.

4. The vehicle window glass lifting device according to claim 2, wherein the camera comprises at least a first camera for capturing the first detection line and a second camera for capturing the second detection line, and

wherein the detection means is configured to detect at least the first blocked state based on an image captured by the first camera, and the second blocked state based on an image captured by the second camera.

5. The vehicle window glass lifting device according to claim 2, wherein the control unit comprises a pinching prevention means that causes the drive mechanism to conduct a pinch prevention operation for preventing pinching by the window glass when the first blocked state or the second blocked state is detected while the window glass is moved, and

wherein the crime prevention operation comprises an operation to forbid the pinch prevention operation.

6. The vehicle window glass lifting device according to claim 2, wherein the crime prevention operation comprises an operation to lock the door of the vehicle.

7. The vehicle window glass lifting device according to claim 2, comprising a warning means that cautions by at least one of light or sound,

wherein the crime prevention operation comprises an operation to caution by the warning means.

8. The vehicle window glass lifting device according to claim 2, comprising an external notification means that communicates with a preset notification object and notifies to the notification object that the foreign object intrudes from the vehicle exterior to the vehicle interior,

wherein the crime prevention operation comprises an operation to notify by the external notification means.

9. A vehicle, comprising the vehicle window glass lifting device according to claim 2.

10. The vehicle window glass lifting device according to claim 1 wherein the crime prevention operation comprises an operation to lift the window glass automatically.

11. The vehicle window glass lifting device according to claim 10, comprising a safety control unit causing the drive mechanism to conduct a safety control operation to detect pinching by the window glass and reverse a moving direction of the window glass and lower automatically when pinching occurs,

wherein the crime prevention operation comprises an operation to finish the safety control operation after the window glass is automatically lowered by a preset predetermined distance and thereafter the window glass is automatically re-lifted while the second blocked state is kept after the second blocked state is detected by the detection means without detecting the first blocked state.

12. The vehicle window glass lifting device according to claim 1, wherein the camera comprises at least a first camera for capturing the first detection line and a second camera for capturing the second detection line, and

wherein the detection means is configured to detect at least the first blocked state based on an image captured by the first camera, and the second blocked state based on an image captured by the second camera.

13. The vehicle window glass lifting device according to claim 1, wherein the control unit comprises a pinching prevention means that causes the drive mechanism to conduct a pinch prevention operation for preventing pinching by the window glass when the first blocked state or the second blocked state is detected while the window glass is moved, and

wherein the crime prevention operation comprises an operation to forbid the pinch prevention operation.

14. The vehicle window glass lifting device according to claim 13, wherein the first detection line and the second detection line are provided on a vehicle interior side of the window glass, and

wherein the pinching prevention means is configured to cause the drive mechanism to conduct a control to reduce an operational speed of the window glass when the first blocked state is detected while the window glass is moved, and cause the drive mechanism to conduct the pinch prevention operation when the second blocked state is detected.

15. The vehicle window glass lifting device according to claim 1, wherein the crime prevention operation comprises an operation to lock the door of the vehicle.

16. The vehicle window glass lifting device according to claim 1, comprising a warning means that cautions by at least one of light or sound,

wherein the crime prevention operation comprises an operation to caution by the warning means.

17. The vehicle window glass lifting device according to claim 1, comprising an external notification means that communicates with a preset notification object and notifies to the notification object that the foreign object intrudes from the vehicle exterior to the vehicle interior,

wherein the crime prevention operation comprises an operation to notify by the external notification means.

18. A vehicle, comprising the vehicle window glass lifting device according to claim 1.
