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: a transmission and reception unit (10) which transmits an ultrasonic wave and receives an ultrasonic wave including a reflection wave of the transmitted ultrasonic wave, and outputs a signal according to a waveform of the received ultrasonic wave; frequency control units (12, 30) which change a frequency of the ultrasonic wave to be transmitted by the transmission and reception unit (10) to a plurality of different frequencies from a driving frequency that is a frequency of an ultrasonic wave for detecting the distance to the object; and abnormality determination units (12, 30) which determine, on the basis of a signal having been output when the ultrasonic wave having the different frequencies from the driving frequency has been transmitted by the transmission and reception unit (10), whether an abnormality is occurring on a function for detecting the distance to the object according to an environmental temperature or a wavelength of the ultrasonic wave transmitted by the transmission and reception unit (10).
(FR) L'invention concerne un dispositif de détection d'objet pourvu : d'une unité d'émission et de réception (10) qui transmet une onde ultrasonore et reçoit une onde ultrasonore comprenant une onde de réflexion de l'onde ultrasonore transmise et délivre un signal selon une forme d'onde de l'onde ultrasonore reçue; d'unités de commande de fréquence (12, 30) qui modifient une fréquence de l'onde ultrasonore devant être transmise par l'unité d'émission et de réception (10) à une pluralité de fréquences différentes à partir d'une fréquence d'entraînement qui est une fréquence d'une onde ultrasonore pour détecter la distance à l'objet; et d'unités de détermination d'anomalie (12, 30) qui déterminent, sur la base d'un signal ayant été émis lorsque l'onde ultrasonore ayant les différentes fréquences à partir de la fréquence d'entraînement a été transmise par l'unité d'émission et de réception (10), si une anomalie se produit sur une fonction pour détecter la distance par rapport à l'objet en fonction d'une température ambiante ou d'une longueur d'onde de l'onde ultrasonore transmise par l'unité d'émission et de réception (10).
(JA) 物体検知装置は、超音波を送信するとともに、送信した超音波の反射波を含む超音波を受信し、受信した超音波の波形に応じた信号を出力する送受信部(10)と、送受信部(10)が送信する超音波の周波数を、物体との距離を検出するための超音波の周波数である駆動周波数とは異なる複数の周波数に変化させる周波数制御部(12、30)と、送受信部(10)が駆動周波数とは異なる周波数の超音波を送信したときに出力した信号に基づいて、物体との距離を検出する機能に、環境温度または送受信部(10)が送信する超音波の波長によって異常が発生するか否かを判定する異常判定部(12、30)と、を備える。
