Title (EN) OBJECT DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION D'OBJET
(JA) 物体検知装置
Abstract:
(EN) This object detection device is provided with: transmission units (3, 4) which transmit ultrasonic waves as probe waves; reception units (3, 7) which receive the ultrasonic waves and output a signal; a distance detection unit (9) which detects the distance to an object on the basis of the output signal of the reception units (3, 7) when the frequency of the ultrasonic waves received by the reception units (3, 7) changes in the same manner as the frequency of the probe waves; and a transmission sound pressure adjustment unit (12) which adjusts the sound pressure of the probe waves such that the sound pressure of the probe waves or reflection waves of the probe waves is within a predetermined transmission target range. The transmission units (3, 4) transmit, as probe waves, first probe waves having a frequency that changes with time and second probe waves having a frequency that changes with time at a rate of change different from that of the first probe waves, and the transmission sound pressure adjustment unit (12) ensures that the sound pressure of the first and second probe waves or reflection waves of the first and second probe waves is within the transmission target range.
(FR) L'invention concerne un dispositif de détection d'objet qui comprend : des unités d'émission (3, 4) qui émettent des ondes ultrasonores en tant qu'ondes de sonde ; des unités de réception (3, 7) qui reçoivent les ondes ultrasonores et délivrent en sortie un signal ; une unité de détection de distance (9) qui détecte la distance à un objet sur la base du signal de sortie des unités de réception (3, 7) lorsque la fréquence des ondes ultrasonores reçues par les unités de réception (3, 7) change de la même manière que la fréquence des ondes de sonde ; et une unité de réglage de pression sonore d'émission (12) qui ajuste la pression sonore des ondes de sonde de telle sorte que la pression sonore des ondes de sonde ou des ondes de réflexion des ondes de sonde se trouve dans une plage cible d'émission prédéfinie. Les unités d'émission (3, 4) émettent, en tant qu'ondes de sonde, des premières ondes de sonde ayant une fréquence qui change avec le temps et des secondes ondes de sonde ayant une fréquence qui change avec le temps à un taux de variation différent de celui des premières ondes de sonde, et l'unité de réglage de pression sonore d'émission (12) assure que la pression sonore des première et seconde ondes de sonde ou des ondes de réflexion des première et seconde ondes de sonde se trouve dans la plage cible d'émission.
(JA) 物体検知装置は、探査波として超音波を送信する送信部(3、4)と、超音波を受信して信号を出力する受信部(3、7)と、受信部(3、7)が受信した超音波の周波数が探査波の周波数と同様に変化したときに、受信部(3、7)の出力信号に基づいて物体との距離を検出する距離検出部(9)と、探査波の音圧を調整して、探査波または探査波の反射波の音圧が所定の送信目標範囲に含まれるようにする送信音圧調整部(12)と、を備える。送信部(3、4)は、探査波として、周波数が時間とともに変化する第1探査波と、周波数が第1探査波とは異なる変化率で時間とともに変化する第2探査波とを送信し、送信音圧調整部(12)は、第1探査波と第2探査波それぞれについて、探査波または探査波の反射波の音圧が送信目標範囲に含まれるようにする。
