PROBLEM TO BE SOLVED: To provide a braking controller of a vehicle, which can reduce possibility that a following vehicle needs to brake suddenly, even when a brake pedal is operated by a driver in an abnormal condition.SOLUTION: The braking controller of a vehicle comprises: abnormality determining means (10, 11, 12, 15) for determining whether a driver of the vehicle is in an abnormal condition where the driver has lost the ability to drive the vehicle; separation distance obtaining means (10, 17) for obtaining a separation distance (Dfv) between the vehicle and a following vehicle behind the same; and deceleration limiting means (10, 20, 21, 22). When the abnormality determining means determines that the driver is in the abnormal condition, the deceleration limiting means performs at least one of: control to limit deceleration, for controlling a braking device of the vehicle, limiting the magnitude of the deceleration of the vehicle to equal to or under a first limit value (|Gijo|), so that the shorter the separation distance is, the less the first limit value is; and control to limit a rate of deceleration change, for controlling the braking device of the vehicle, limiting the magnitude of the time rate of the deceleration change to equal to or under a second limit value (|ΔGa|), so that the shorter the separation distance (Dfv) is, the less the second limit value is.SELECTED DRAWING: Figure 1
【課題】運転者が異常状態に陥っている状況においてブレーキペダルが操作された場合であっても、後続車両に急制動を必要とさせてしまう可能性を低減させる【解決手段】車両の運転者が同車両を運転する能力を失っている異常状態にあるか否かの判定を行う異常判定手段(10,11,12,15)と、車両と同車両の後続車両との車間距離(Dfv)を取得する車間距離取得手段(10,17)と、異常判定手段により運転者が異常状態にあると判定された場合、車両の減速度の大きさを車間距離が短いほど小さい第1制限値(|Gijo|)以下に制限するように車両の制動装置を制御する減速度制限制御、及び、減速度の時間変化率の大きさを車間距離(Dfv)が短いほど小さい第2制限値(|ΔGa|)以下に制限するように車両の制動装置を制御する減速度変化率制限制御、の少なくとも一方を実施する減速度制限手段(10,20,21,22)と、を備える。【選択図】図1
