VEHICLE DRIVING SUPPORT DEVICE AND VEHICLE DRIVING SUPPORT SYSTEM

To provide a vehicle driving support device and a vehicle driving support system that can actuate an automatic brake at an appropriate timing.SOLUTION: A vehicle driving support device includes: a vehicle behavior computation section for computing a transition of behavior of a vehicle including speed of the vehicle traveling along a travel route, on the basis of the travel route of the vehicle, obstruction information and vehicle information; and a brake operation position computation section for calculating a brake operation position of an automatic brake for avoiding collision between the vehicle and an obstruction. If the vehicle behavior computation section determines that there is a possibility of collision and sudden braking, correction is made to a brake operation position that relaxes the sudden braking.SELECTED DRAWING: Figure 2 【課題】自動ブレーキを適切なタイミングで作動させることができる車両運転支援装置及び車両運転支援システムを提供する【解決手段】車両運転支援装置は、車両の走行経路、障害物情報及び車両情報に基づいて、走行経路に沿って走行する車両の速度を含む車両の挙動の推移を演算する車両挙動演算部と、車両と障害物との衝突を回避するための自動ブレーキのブレーキ作動位置を算出するブレーキ作動位置演算部とを備え、車両挙動演算部で、衝突の可能性があり、且つ急制動と判定された場合、急制動を緩和するブレーキ作動位置に補正する。【選択図】図２
