用障害物検出装置。[Claims for Utility Model Registration] (1) A device mounted on an automatic driving vehicle traveling on a running road to detect obstacles existing on the running road using ultrasonic waves in order to prevent collisions with the obstacles. In the obstacle detection device for an automatic driving vehicle, horns 2 are installed at the front of the driving vehicle in the direction of travel.
at least one ultrasonic transmitter 5 and at least one ultrasonic receiver 6, the ultrasonic wave that is about to enter the horn from the road surface side at least in front of the lower part of the ultrasonic receiver 6. An obstacle detection device for an automatic driving vehicle, characterized in that an ultrasonic blocker 3 is provided to block the ultrasonic waves. (2) The obstacle detection device for an automatic driving vehicle according to claim 1, wherein a drainage hole 2B is provided near the ultrasonic wave transmitter 5 and the ultrasonic wave receiver 6 at the lower part of the base side of the horn 2. (3) Obstacle detection for automatic driving vehicles that is mounted on an automatic driving vehicle traveling on a driving path and uses ultrasonic waves to detect obstacles in the driving path in order to prevent collisions with the obstacles. In the device, horns 2 are installed at the front of the traveling vehicle in the traveling direction.
A plurality of ultrasonic transmitters 5 and a plurality of ultrasonic receivers 6 are arranged side by side on the base 1, each having an inclined surface continuous with the inclined surface of the horn, and a lower front portion of the horn. It protrudes from the ultrasonic wave transmitter 5 to serve as an ultrasonic propagation direction regulating body, and to the ultrasonic receiver 6 to prevent ultrasonic waves from entering the horn from the road side. An obstacle detection device for an automatic driving vehicle, characterized in that a protruding body 3 functioning as a sound wave blocker is provided integrally with the base body 1.
