To provide a device for reducing collision damage during left/right turns to prevent collision accidents during left/right turns and to reduce collision damage.SOLUTION: A device for reducing collision damage during left/right turns 200 includes: a position acquisition part 201 for acquiring a position of an obstacle; a left/right turn determination part 205 for determining whether a left/right turn is going to be made; a collision risk determination part 206 for determining whether or not there is a risk of collision with the obstacle by estimating a turning track of each vertex, assuming that the plane shape of an own vehicle is rectangular when attempting a left/right turn and that the estimated turning track of each vertex and a position of the obstacle are input; a collision damage reduction part 207 during left/right turns for alerting a driver that there is a risk of collision between the vehicle and the obstacle and intervening in driving when there is a risk of collision with the obstacle; a steering angle acquisition part 202 for acquiring a steering angle; a yaw rate acquisition part 203 for acquiring a yaw rate; a vehicle speed acquisition part 204 for acquiring a vehicle speed; and a vehicle body slip angle acquisition part 209 for acquiring a vehicle body slip angle.SELECTED DRAWING: Figure 1
【課題】右左折時の衝突事故を予防したり衝突被害を軽減する右左折時衝突被害軽減装置を提供する。【解決手段】障害物の位置を取得する位置取得部201と、右左折をしようとしているのか否かを判定する右左折判定部205と、右左折をしようとしている時に自車平面形状を矩形状と見なし各頂点の旋回軌道を推定すると共に推定した各頂点の旋回軌道と障害物の位置とを入力とし障害物との衝突リスクが有るか否かを判定する衝突リスク判定部206と、障害物との衝突リスクが有る時に自車と障害物との衝突リスクが有る事をドライバに警告したり運転操作に介入したりする右左折時衝突被害軽減部207と、操舵角を取得する操舵角取得部202と、ヨーレートを取得するヨーレート取得部203と、車速を取得する車速取得部204と、車体スリップ角を取得する車体スリップ角取得部209と、を備える右左折時衝突被害軽減装置200によって課題を解決する。【選択図】図1
