  • Publication number: 20240040222
    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.

  • Publication number: 20220157096
    Abstract: A vehicular control system includes a first unit for transmitting data, a second unit for receiving the data, and a data communication line between a first connection portion connected to the first unit and a second connection portion connected to the second unit. The vehicular control system determines whether the first unit is in a data transfer performable state in which the first unit can transfer data to the second unit or in a data transfer nonperformable state in which the first unit cannot transfer data to the second unit. When the first unit is in the data transfer nonperformable state, a predetermined anomaly reporting signal different from the data is transmitted from the first connection portion to the second connection portion via the data communication line. When the first unit is in the data transfer performable state, the anomaly reporting signal is not transmitted to the second connection portion.
