PROBLEM TO BE SOLVED: To provide an ultrasonic object detection device with which it is possible to suppress a rear door from being erroneously detected to be an object at the back of a vehicle.SOLUTION: Provided is an ultrasonic object detection device (13) applied to a vehicle (100) the rear door (10) of which is openable/closable by an actuator (11), the ultrasonic object detection device comprising: transmission/reception units (21-23), installed on other than a rear door at the back of a vehicle, for transmitting a transmission signal as a pulsed ultrasonic wave to the rear of the vehicle and receiving a reflection signal as a reflected wave from an object; a determination unit (25) for determining, using a threshold, whether the object exists in a prescribed range at the back of the vehicle on the basis of the reflection signal; and an open/closed state recognition unit (25) for recognizing the open/closed state of the rear door, the determination unit changing the threshold in a direction in which the presence of an object becomes difficult to determine, on condition that the rear door is recognized by the open/closed state recognition unit as being open or closed.SELECTED DRAWING: Figure 1

    【課題】後部ドアを車両後方の物体と誤検知することを抑制する事のできる超音波式物体検知装置を提供する。【解決手段】アクチュエータ(11)により後部ドア(10)を開閉可能な車両(100)に適用される超音波式の物体検知装置(13)であって、車両の後部において後部ドア以外に設置され、パルス状の超音波としての送信信号を車両の後方に送信し、物体からの反射波としての反射信号を受信する送受信部(21〜23)と、反射信号に基づいて車両の後方の所定範囲に物体が存在するか、閾値を用いて判定する判定部(25)と、後部ドアの開閉状態を認識する開閉状態認識部(25)と、を備え、判定部は、開閉状態認識部により後部ドアが開閉中であると認識されたことを条件として、物体が存在すると判定されにくくする方向に閾値を変更することを特徴とする超音波式物体検知装置。【選択図】 図1
