To output driving assist information devoid of annoyance even when an intersection to be passed is an intersection where a sensitive traffic signal is installed.SOLUTION: A driving assist system for vehicles of the present invention includes a driving assist control unit 10 including a signal information acquisition block 11 that acquires lighting time information on a trunk-side traffic signal at an intersection where a sensitive traffic signal is installed, a remaining distance calculation block 14 that obtains a remaining distance of a vehicle to the intersection, and a driving assist information output block (16 and 17) that outputs driving assist information obtained based on the lighting time information and remaining distance, an acquisition unit (22) that acquires any of information on a vehicle speed of an intersecting vehicle, which travels on an intersecting road that intersects a trunk road at the intersection, and the remaining distance to the intersection, an arrival time when the intersecting vehicle arrives at the intersection, and lighting time information on an intersecting road-side traffic signal. The driving assist control unit updates the lighting time information on the trunk-side traffic signal on the basis of information acquired from a road-vehicle communication unit, and allows the driving assist information output block to output the driving assist information on the basis of the updated lighting time information.SELECTED DRAWING: Figure 3
【課題】 通過する交差点が、感応式信号機が設置された交差点であっても、煩わしさのない運転支援情報を出力する。【解決手段】 本発明の車両用運転支援装置は、感応式信号機が設置された交差点の幹線側信号機の点灯時間情報を取得する信号情報取得部11と、車両の交差点までの残距離を求める残距離算出部14と、点灯時間情報と残距離とから求めた運転支援情報を出力する運転支援情報出力部(16、17)と、を有する運転支援制御部10と、交差点において幹線道路に交差する交差道路を走行する交差側車両の車速と交差点までの残距離の情報、交差側車両が交差点に到達する到達時刻、あるいは、交差側信号機の点灯時間情報、のいずれかを取得する取得部(22)と、を備え、運転支援制御部は、路車間通信部により取得した情報を基に、幹線側信号機の点灯時間情報を更新し、更新した点灯時間情報に基づいて運転支援情報出力部により運転支援情報を出力する。【選択図】図3
