Vehicle-use rear side warning device and vehicle-use rear side warning method

A vehicle-use rear side warning device, comprising:

• a sensor unit that detects an approaching moving object existing on the rear side of the own vehicle;
• a vehicle condition detector that detects an operating condition of the own vehicle;
• a warning output unit that displays visual information in the own vehicle and causes auditory information, and contact information formed of a vibration, to be generated;
• and
• a central processor that causes the warning output unit to operate based on outputs of the periphery monitoring camera unit, the sensor unit, and the vehicle condition detector, wherein
• the central processor has an approaching moving object detector that detects an approaching moving object existing within a predetermined range on the rear side of the own vehicle based on outputs of the periphery monitoring camera unit and the sensor unit, a relative speed detector that detects relative speeds of an approaching moving object detected by the approaching moving object detector and the own vehicle, and a warning output determiner that, when an approaching moving object is detected by the approaching moving object detector and a matter that the own vehicle is attempting to change lane is detected by the vehicle condition detector, causes a warning of the warning output unit to be generated when a relative speed detected by the relative speed detector exceeds a reference relative speed with respect to which a lane change can be carried out, based on outputs of the approaching moving object detector, the relative speed detector, and the vehicle condition detector.
