An opening/closing body drive device includes a drive mechanism that moves an opening/closing body between an opening position and a closing position relative to a frame portion having an opening, a control unit for controlling the drive mechanism, a light source unit including a light emitting element emitting a non-visible light and radiating the non-visible light to a detection line formed of a retroreflective material along at least a part of the frame portion, and a camera including an incident lens into which the non-visible light radiated from the light source unit and reflected by the detection line enters. At least of a part of the light source unit is arranged in front of the incident lens when the incident lens is viewed along an optical axis thereof from a side of the opening.

Opening/closing body drive device, vehicle door, and vehicle

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 on a vehicle interior side of the window glass, the detection line being 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 to detect a blocked state in which at least a part of the detection line is blocked by a foreign object, and a pinching prevention means that causes the drive mechanism to conduct a pinch prevention operation for preventing pinching by the window glass when the blocked state is detected by the detection means while the window glass is moved by the drive mechanism.

The incident lens is formed non-circular by cutting off an end of the incident lens when viewed in an optical axis direction thereof, and at least a part of the light source unit is arranged in a region where the end is cut off.

A vehicle window glass raising/lowering device includes a drive mechanism, a control unit for controlling the drive mechanism, and 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 inner circumferential surface of the frame portion so that an optical axis of the optical system passes through the opening.

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.

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.
