To provide a driving support controller and a vehicle that can support the driving of the driver of an own vehicle at an appropriate timing.SOLUTION: A collision possible time T_ttc, which is the time it takes for another vehicle coming closer to an own vehicle (vehicle 1) from the back side to reach the vehicle 1, is calculated on the basis of the relative ratio to another vehicle (the rate of another vehicle Sp2 to the rate of the own vehicle Sp1) and the distance D between vehicles. A driving support controller (ECU 2) for supporting the driving (displaying a warning or issuing an alarm) of the driver of the vehicle 1 has a TTC threshold changing unit 12 for increasing or reducing the TTC threshold value Th according to the state of another vehicle when the collision possible time T_ttc is equal to or less than a predetermined TTC threshold value Th.SELECTED DRAWING: Figure 2
【課題】 自車両のドライバにとって相応しいタイミングで該ドライバに対して運転支援を行うことができる運転支援制御装置及び車両を提供する。【解決手段】 自車両(車両1)の後側方から接近する他車両との相対速度(他車両速度Sp2−自車両速度Sp1)及び車間距離Dに基づき、他車両が車両1に達するまでの衝突可能性時間T_ttcを算出し、衝突可能性時間T_ttcが所定のTTC閾値Th以下である場合、車両1のドライバに対して運転支援(警告表示や警報等)を行う運転支援制御装置(ECU2)において、他車両の状態に応じて、TTC閾値Thを増加させる又は減少させるTTC閾値増減部12を具備する。【選択図】 図2
