DRIVING SUPPORT DEVICE, DRIVING SUPPORT METHOD AND PROGRAM

To provide a driving support device capable of reflecting a state of a vehicle when determining the presence/absence of steps on the road surface.SOLUTION: A driving support device 100 comprises: a distance determination part 131 configured to determine whether or not the distance between a distance determination sensor 111 provided to the vehicle and the road surface is a distance or more represented by a distance determination threshold; a timing detection part 132 configured to detect completion timing of change of total weight of the vehicle; and an adjustment part 120 configured so as to, when the timing detection part detects the completion timing of change, adjust the distance determination threshold.SELECTED DRAWING: Figure 1 【課題】路面における段差等の有無を判定する際、車両の状態を判定に反映させられる運転支援装置を提供する。【解決手段】運転支援装置１００は、車両に設けられた距離判定用センサ１１１と路面との距離が、距離判定閾値の示す距離以上か否かを判定する距離判定部１３１と、前記車両の総重量の変動完了タイミングを検知するタイミング検知部１３２と、前記タイミング検知部が前記変動完了タイミングを検知すると前記距離判定閾値を調整する調整部１２０と、を備える。【選択図】図１
