PROBLEM TO BE SOLVED: To restrain an own vehicle from stopping in the middle of an intersection and the like through driving support that adjusts an inter-vehicle distance to a preceding vehicle.SOLUTION: A state recognition unit 10 recognizes a state of a structure of a front road based on results of detection by sensors 2, 3 and 4. An entrance/exit determination unit 21 determines a position of an entrance point and an exit point of an intersection of the road based on the recognized structure of the road. A correction unit 23 corrects a present position mapped on a road map based on the recognized structure of the road. An intersection information derivation unit 23 derives intersection information including a distance to the intersection and a distance to the exit point from the entrance point based on map information, the corrected present position, and a position of the entrance and exit points of the intersection. A target distance setting unit 24 sets a target inter-vehicle distance so that a position separated by the inter-vehicle distance from a preceding vehicle does not fall between the entrance point and the exit point of the intersection part based on the intersection information.SELECTED DRAWING: Figure 1
【課題】先行車両との車間距離を調節する運転支援で、自車両が交差点等の途中で停止することを抑制する。【解決手段】状況認識部10は、センサ2,3,4による検出結果に基づき、前方の道路の構造の状況を認識する。入口・出口特定部21は、認識された道路の構造に基づき、道路の交差部の入口地点及び出口地点の位置を特定する。補正部23は、認識された道路の構造に基づき、道路地図上に対応付けられた現在位置を補正する。交差部情報導出部23は、地図情報と、補正された現在位置と、交差部の入口・出口地点の位置とに基づき、交差部までの距離と、入口地点から出口地点までの距離とを含む交差部情報を導出する。目標距離設定部24は、交差部情報に基づき、先行車両から車間距離を空けた位置が交差部の入口地点から出口地点までの間に入らないように目標車間距離を設定する。【選択図】図1
