Abstract: The driving assistance device includes: a fluctuation amount recognition unit; a driver abnormality recognition unit that recognizes an abnormality of a driver of another vehicle based on a captured image of an external camera provided in a vehicle; an abnormal state determination unit that determines whether the other vehicle is in a fluctuation abnormality state based on a comparison result between a fluctuation amount of the other vehicle and the fluctuation threshold; and a notification control unit that performs notification regarding the fluctuation abnormality state. The abnormal state determination unit determines whether a fluctuation abnormal state is present, with the fluctuation threshold value in a case where an abnormality of the driver of the other vehicle is recognized as a smaller absolute value than the fluctuation threshold value in a case where an abnormality of the driver of the other vehicle is not recognized.

Abstract: An optical axis position adjuster according to the present disclosure includes a target board, a leg portion that supports the target board, and an installation auxiliary jig that connects the leg portion and the vehicle. The leg portions can be installed horizontally with respect to the ground. The installation auxiliary jig is connected to a connecting portion provided in the leg portion and is connected to an emblem provided in the vehicle. The connecting portion is disposed at the center of the leg portion, and the emblem is disposed at the center of the vehicle in the vehicle width direction. Therefore, it is possible to connect the vehicle and the leg portions such that the center of the target board and the center of the vehicle in the vehicle width direction coincide with each other in a plan view.

Abstract: A vehicle inspection system acquires a first camera image captured by a first camera and a second camera image captured by a second camera, calculates a first optical axis coordinate value from the first camera image and a second optical axis coordinate value from the second camera image, determines whether there is an abnormality in each of the first optical axis coordinate value and the second optical axis coordinate value, and identifies an abnormality factor portion causing an abnormality in one or both of the first optical axis coordinate value and the second optical axis coordinate value from among the first camera, the second camera, and the vehicle body of the vehicle, based on a combination of the presence or absence of the abnormality in the first optical axis coordinate value and the presence or absence of the abnormality in the second optical axis coordinate value.

Abstract: An anti-fogging system according to the present disclosure includes an anti-fogging device that suppresses fogging of glass of a vehicle, and a control device that controls the anti-fogging device. The control device is configured to execute a process of operating an anti-fogging device when a predetermined condition is satisfied, a process of acquiring information on a conversation situation including at least whether or not a vehicle occupant is talking, and a process of changing a predetermined condition based on information on a conversation situation.

Abstract: Provided is an in-vehicle camera shield state determination device which determines a shield state of an external camera of a vehicle, the device determines whether or not shield is detected by image processing of a captured image, determines whether or not an object is close to the vehicle in an imaging direction of the external camera, based on a detection result of an external sensor of the vehicle, determines whether or not the external camera is in the shield state, based on a detection result of a shield detection unit and a determination result of a proximity determination unit, and even if shield is detected by image processing of the captured image, when it is determined that the object is close to the vehicle in the imaging direction of the external camera, it is not determined that the external camera is in the shield state.

Abstract: A vehicle driving support device performs extraneous matter notification for notifying an occupant of a vehicle that extraneous matter is adhered to a viewing-angle window part which is a part of a window of the vehicle in a viewing angle range of an onboard camera which is mounted in the vehicle such that an outside view from the vehicle is imaged from the inside of the vehicle or a camera lens which is a lens of the onboard camera, performs a process of detecting the extraneous matter adhering to the viewing-angle window part or the camera lens when the vehicle is stopped, and does not perform the extraneous matter notification even if the extraneous matter adhering to the viewing-angle window part or the camera lens is detected when the vehicle is stopped and is not in a state in which the vehicle is predicted to be about to start traveling.
