To provide a downhill running speed control device which enables suppression of a deviation between a vehicle speed desired by a driver and an actual vehicle speed.SOLUTION: A downhill running speed control device includes target vehicle speed change means (23) that changes a target vehicle speed (V*) according to acceleration operation or braking operation, while automatic braking is applied to a vehicle during downhill running on the basis of the target vehicle speed (V*). The downhill running speed control device is equipped with road surface gradient detection means (21) detecting a road surface gradient of a downhill road. When the road surface gradient detection means (21) detects a first road surface gradient (θ1) in a state that acceleration operation and braking operation are not performed, the target vehicle speed (V*) is set to be a first vehicle speed (V1) that is a vehicle speed upon detection of the first road surface gradient (θ1) .SELECTED DRAWING: Figure 2
【課題】本発明は、運転者の所望する車速と実際の車速との乖離を抑制できる降坂路走行速度制御装置を提供すること。【解決手段】本発明に係る降坂路走行速度制御装置は、降坂路走行中の車両を目標車速(V*)に基づいて自動制動しつつ、アクセル操作またはブレーキ操作に応じて目標車速(V*)を変更する目標車速変更手段(23)を有する降坂路走行速度制御装置において、降坂路の路面勾配を検出する路面勾配検出手段(21)を備え、アクセル操作および前記ブレーキ操作がされていない状態で、路面勾配検出手段(21)が第1路面勾配(θ1)を検出したとき、目標車速(V*)は第1路面勾配(θ1)を検出したときの車速である第1車速(V1)に設定される、ことを特徴とする。【選択図】図2
