To appropriately control timing of an alarm by learning motions of an own vehicle.SOLUTION: A driving support device 10 has: a speed change acquisition part 38 which acquires a detection result of a degree of speed change of an own vehicle; a relative speed acquisition part 30 which acquires a detection result of relative speed to a preceding vehicle of the own vehicle; a vehicular gap acquisition part 32 which acquires a detection result of a vehicular gap between the own vehicle and the preceding vehicle; a determination part 36 which determines whether the own vehicle is in a proximity state to the preceding vehicle based on the relative speed and the vehicular gap; and an alarm control part 40 which sets alarm timing which is the timing for outputting an alarm to a driver of the own vehicle based on the timing in which it is determined to be in the proximity state, in which the alarm control part 40 changes the alarm timing based on the detection result of the degree of speed change of the own vehicle after it is determined to be in the proximity state.SELECTED DRAWING: Figure 2
【課題】自車両の動作を学習して、警報のタイミングを適切に制御する。【解決手段】運転支援装置10は、自車両の速度変化の度合いの検出結果を取得する速度変化取得部38と、自車両の先行車両に対する相対速度の検出結果を取得する相対速度取得部30と、自車両と先行車両との車間距離の検出結果を取得する車間距離取得部32と、相対速度と車間距離とに基づき、自車両が先行車両に対して近接状態であるかを判定する判定部36と、近接状態であると判定されたタイミングに基づき、自車両の運転者に警報を出力するタイミングである警報タイミングを設定する警報制御部40と、を有し、警報制御部40は、近接状態であると判定されてからの自車両の速度変化の度合いの検出結果に基づき、警報タイミングを変更する。【選択図】図2
