Abstract:
1. A solid object detection device for detecting a solid object traveling in an adjacent traffic lane that is adjacent across a dividing line serving as a boundary to a traffic lane traveled by a vehicle, the solid object detection device comprising: an image-capturing unit configured to be installed for capturing an image including the dividing line and a predetermined region of the adjacent traffic lane, the image-capturing unit being installed in the vehicle; a solid object assessment unit programmed to assess whether or not a solid object is present in the predetermined region image captured by the image-capturing unit; a lateral position detection unit that detects a vehicle-widthwise distance between the dividing line and a vehicle position in the lane traveled by the vehicle from the image captured by the image-capturing unit; a region setting unit programmed to enlarge a size of the predetermined region that is positioned on the side where the dividing line is located farther outward in the vehicle-width direction in accordance with an increase in the vehicle-widthwise distance to the dividing line detected by the lateral position detection unit; and a traffic lane change detection unit that detects an existence of a traffic lane change made by the vehicle; the amount by which the size of the predetermined region is enlarged outward in the vehicle-width direction being reduced by the region setting unit when a traffic lane change made by the vehicle is detected by the traffic lane change detection unit.
