The present invention is provided with: a camera (10) for imaging the rear of a vehicle; three-dimensional object detection units (33, 37) for detecting a three-dimensional object positioned in right and left detection regions (A1, A2) on the basis of image information; a three-dimensional object determination unit (34) for determining that the detected three-dimensional object is another vehicle (VX) when the movement speed of the detected three-dimensional object is within a pre-set range; a precipitation state detection unit (41) for detecting a precipitation state which includes when there is rainfall and when a water film is formed on the road surface due to rainfall; and a control unit (39) for outputting a control command for narrowing the set range of the movement speed for determining whether the three-dimensional object is another vehicle (VX) when the precipitation state was detected.
