PROBLEM TO BE SOLVED: To provide a speed-limit setting device capable of appropriately setting a speed limit when a lighting type speed sign is turned off.SOLUTION: A speed-limit setting device for setting a speed limit of a vehicle on the basis of an image of a lighting type speed sign included within an imaging range of an on-vehicle camera includes: a sign determination unit for determining whether or not the lighting type speed sign is included within the imaging range of the on-vehicle camera on the basis of map information including a position of the vehicle on a map and a position of the lighting type speed sign on the map; a shield determination unit for determining whether or not a shield exists between the vehicle and the lighting type speed sign when the lighting type speed sign is determined to be included within the imaging range of the on-vehicle camera and in a case where a speed sign recognition unit cannot recognize an image of the lighting type speed sign; and a speed-limit setting unit for setting a prescribed specific speed as a speed limit of the vehicle when no shield is determined to exist between the vehicle and the lighting type speed sign by the shield determination unit.SELECTED DRAWING: Figure 2
【課題】点灯式速度標識の消灯時に適切に制限速度を設定することができる制限速度設定装置を提供する。【解決手段】車載カメラの撮像範囲内に含まれる点灯式速度標識の画像に基づいて車両の制限速度を設定する制限速度設定装置であって、車両の地図上の位置と点灯式速度標識の地図上の位置を含む地図情報とに基づいて、車載カメラの撮像範囲内に点灯式速度標識が含まれるか否かを判定する標識判定部と、車載カメラの撮像範囲内に点灯式速度標識が含まれると判定された場合に、速度標識認識部が点灯式速度標識の画像を認識できなかったとき、車両と点灯式速度標識の間に遮蔽物が存在するか否かを判定する遮蔽物判定部と、遮蔽物判定部により車両と点灯式速度標識の間に遮蔽物が存在しないと判定された場合、予め決められた規定速度を車両の制限速度として設定する制限速度設定部と、を備える。【選択図】図2
