PROBLEM TO BE SOLVED: To provide a vehicle obstacle detection device capable of reducing the degree of a variation in a distance from a sensor attachment surface of a vehicle to a boundary of a notification range depending on a distance to an ultrasonic sensor, and suppressing a discomfort to a notification content representing the direction in which an obstacle has been detected.SOLUTION: A notification control unit determines whether to use a first indirect wave distance (D2) that is a distance to an obstacle calculated by receiving, by an ultrasonic sensor 10RLC, an ultrasonic wave transmitted from an ultrasonic sensor 10RL and a second indirect wave distance (D3) that is a distance to the obstacle calculated by receiving, by the ultrasonic sensor 10RL, an ultrasonic wave transmitted from the ultrasonic sensor 10RLC in determination as to whether to notify a user that the obstacle was detected in a left rear notification area, on the basis of a first direct wave distance (D1) that is a distance to the obstacle calculated by the ultrasonic sensor 10RL by a direct wave and a second direct wave distance (D4) that is a distance to the obstacle calculated by the ultrasonic sensor 10RLC by the direct wave.SELECTED DRAWING: Figure 6

    【課題】車両のセンサ取付面から報知範囲の境界までの距離が、超音波センサまでの距離によって変動する程度を小さくし、かつ、障害物を検出した方向を表している報知内容の違和感が少ない車両用障害物検出装置を提供する。【解決手段】報知制御部は、左後報知エリアに障害物を検出したと報知するか否かの判断に、超音波センサ10RLが送信した超音波を超音波センサ10RLCが受信して算出した障害物までの距離である第1間接波距離(D2)と、超音波センサ10RLCが送信した超音波を超音波センサ10RLが受信して算出した障害物までの距離である第2間接波距離(D3)を用いるか否かを、超音波センサ10RLが直接波により算出した障害物までの距離である第1直接波距離(D1)と、超音波センサ10RLCが直接波により算出した障害物までの距離である第2直接波距離(D4)とに基づいて決定する。【選択図】図6
