To provide a braking ability estimation device capable of improving an estimation accuracy of a braking ability.SOLUTION: A braking ability estimation device is mounted on a vehicle and estimates a braking ability that is an ability to stop the vehicle. The braking ability estimation device comprises: a road surface condition determination unit 112 for sequentially determining a road surface condition of a road on which an own vehicle 1 that is the vehicle equipped with the braking ability estimation device is traveling; and a braking ability estimation unit 114 for sequentially estimating the braking ability of the own vehicle 1 based on the road surface condition determined by the road surface condition determining unit 112. The braking ability of the own vehicle 1 changes according to the road surface condition. Therefore, by estimating the braking ability of the own vehicle 1 based on the road surface condition, the braking ability of the own vehicle 1 can be estimated more accurately than when the road surface condition is not taken into consideration.SELECTED DRAWING: Figure 1
【課題】ブレーキ能力の推定精度を向上させることができるブレーキ能力推定装置を提供する。【解決手段】車両に搭載され、車両を停止させる能力であるブレーキ能力を推定するブレーキ能力推定装置であって、ブレーキ能力推定装置が搭載されている車両である自車両1が走行している道路の路面状態を逐次決定する路面状態決定部112と、路面状態決定部112が決定した路面状態に基づいて、自車両1のブレーキ能力を逐次推定するブレーキ能力推定部114とを備える。自車両1のブレーキ能力は路面状態により変化する。したがって、路面状態に基づいて自車両1のブレーキ能力を推定することで、路面状態を考慮しない場合に比較して、精度よく自車両1のブレーキ能力を推定することができる。【選択図】図1
