To enable recognizing in advance a place where sudden acceleration needs to be suppressed, and to appropriately suppress occurrence of sudden acceleration due to a mistake in stepping-on operation at the place.SOLUTION: A driving supporting device for a vehicle reads own vehicle position information estimated by an own vehicle position estimation calculation part 12a (S6); refer to road map information of a road map database 16 on the basis of the own vehicle position information, and reads road map information in front of an own vehicle position (S7); then, determines whether or not there is an intersecting road in front of the own vehicle M (S8); predicts, from a lighting direction of a blinker, whether the own vehicle M will turn right or left at the intersecting road (S10); sets a non-travelable area along the intersecting road in accordance with the predicted right or left turn of the own vehicle M (S12, S13); sets an acceleration gain Ka that suppresses acceleration in accordance with an arrival distance Li from the own vehicle M to the non-travelable area (S19); and corrects a basic target acceleration αbs with the acceleration gain Ka to set a target acceleration α (S24).SELECTED DRAWING: Figure 2
【課題】急加速を抑制する必要のある場所を事前に認識し、当該場所において踏み間違いによる急加速の発生を適正に抑制することができるようにする。【解決手段】自車位置推定演算部12aで推定した自車位置情報を読込み(S6)、この自車位置情報に基づいて道路地図データベース16の道路地図情報を参照し、自車位置前方の道路地図情報を読込む(S7)。そして自車両Mの前方に交差道路があるか否かを調べ(S8)、ウインカの点灯方向から自車両Mが交差道路を右折するか、左折するかを予測し(S10)、予測した自車両Mの右折、或いは左折に応じ、交差道路に沿って走行不可領域を設定し(S12,S13)、自車両Mから走行不可領域までの到達距離Liに応じて、加速を抑制する加速度ゲインKaを設定し(S19)、この加速度ゲインKaで基本目標加速度αbsを補正して、目標加速度αを設定する(S24)。【選択図】図2
