PROBLEM TO BE SOLVED: To provide a device for estimating a collision probability between a vehicle and a pedestrian in consideration of variation in pedestrian position detection by sensors such as a camera and a radar.SOLUTION: A collision probability estimation device 10 includes: a vehicle speed detection section 2 for detecting a speed of a traveling vehicle; a pedestrian position detection section 4 for detecting a position of a pedestrian crossing in front of a traveling vehicle; and a collision probability calculation section 6 for calculating a collision probability of collision between a vehicle and a pedestrian on the basis of vehicle speed information detected by the vehicle speed detection section 2 and pedestrian position information detected by the pedestrian position detection section 4. The collision probability calculation section 6 calculates a speed of a pedestrian on the basis of pedestrian position information detected by the pedestrian position detection section 4, calculates distribution values of a position and a speed of a pedestrian respectively based on pedestrian position information and a calculated speed of a pedestrian, and calculates a collision probability between a vehicle and a pedestrian on the basis of the calculated distribution values and vehicle speed information.SELECTED DRAWING: Figure 1
【課題】カメラやレーダなどのセンサによる歩行者の位置検出のばらつきを考慮して、車両と歩行者との衝突確率を推定する装置を提供する。【解決手段】走行する車両の速度を検出する車両速度検出部2と、走行する車両の前方を横切る歩行者の位置を検出する歩行者位置検出部4と、車両速度検出部2により検出された車両の速度情報と、歩行者位置検出部4により検出された歩行者の位置情報とに基づいて、車両と歩行者とが衝突する衝突確率を算出する衝突確率演算部6とを備える衝突確率推定装置10であって、衝突確率演算部6は、歩行者位置検出部4により検出された歩行者の位置情報から歩行者の速度を算出し、歩行者の位置情報と算出した歩行者の速度とから歩行者の位置と速度の分散値をそれぞれ算出し、算出したこれらの分散値と車両の速度情報とから車両と歩行者との衝突確率を算出する。【選択図】 図1
