PROBLEM TO BE SOLVED: To provide a vehicle-purpose support system that can determine a support level in accordance with a sense of distance of a driver with respect to an object around a vehicle.SOLUTION: The vehicle-purpose support system comprises: a first distance acquisition unit 15 and second distance acquisition unit 20 that acquire a relative distance with respect to objects existing around a vehicle; a behavior learning unit 18 that, when the vehicle decelerates at a prescribed deceleration level, acquires an image from an imaging camera 55, and the relative distance from the first distance acquisition unit 15, respectively, and stores the acquired relative distance in association with the acquired image as the shortest distance with respect to the object as a past image 31; an ambient state judgement unit 22 that judges a similarity degree between the acquisition image of the imaging camera 55 and the past image 31; and a judgement unit 24 that, when the similarity degree is equal to or greater than a prescribed similarity degree, acquires the shortest distance associated with the past image 31, compares the shortest distance with the relative distance acquired from the second distance acquisition unit 20, and judges which of an evocation of attention to the object or automatic braking is performed.SELECTED DRAWING: Figure 1
【課題】車両の周囲の物体に対する運転者の距離感に応じて支援のレベルを決定することのできる車両用支援システムを提供する。【解決手段】車両用支援システムは、当該車両の周囲に存在する物体との相対距離を取得する第1距離取得部15及び第2距離取得部20と、当該車両が所定の減速度合で減速したときに、撮像カメラ55から画像を、第1距離取得部15から相対距離をそれぞれ取得するとともに、取得した相対距離を物体に対する最短距離として、取得した画像に関連付けて過去画像31として記憶する行動学習部18と、撮像カメラ55の取得画像と過去画像31との類似度を判定する周囲状況判断部22と、当該類似度が所定の類似度以上であるとき当該過去画像31に関連付けられた最短距離を取得し、最短距離と第2距離取得部20から取得した相対距離とを比較して、物体に対する注意喚起及び自動制動のいずれを行うかを判定する判定部24とを備える。【選択図】図1
