Claims (1)
を配列し、送信タイミング回路の制御の下に前記送波器
を駆動し、該送波器より発信された超音波信号が障害物
にて反射され前記受波器に受信されるまでの時間から前
記障害物との距離を測定することにより障害物を検知す
るようにした障害物検知装置において、前記送信タイミ
ング回路により受波器の両側の送波器を同時に駆動し、
該受波器で受信した超音波信号を−の計測手段で処理す
るようにしてなる障害物検知装置。On one side of the detection section, transmitters are arranged with receivers for ultrasonic signals sandwiched between them, and the transmitters are driven under the control of a transmission timing circuit to generate ultrasonic waves emitted from the transmitters. In an obstacle detection device that detects an obstacle by measuring the distance to the obstacle from the time it takes for a signal to be reflected by the obstacle and received by the receiver, the transmission timing circuit Drives the transmitters on both sides of the receiver at the same time,
An obstacle detection device configured to process an ultrasonic signal received by the receiver using a measuring means.
