|1. (WO2016063525) ULTRASONIC OBJECT DETECTION DEVICE|
TOYOTA JIDOSHA KABUSHIKI KAISHA
|Title:||ULTRASONIC OBJECT DETECTION DEVICE|
This ultrasonic object detection device is equipped with: one or more transmission/receiving units (11) for transmitting an ultrasonic transmission wave to the exterior of a vehicle and receiving a reflected wave produced by reflection by an object of the transmission wave, and installed in the vehicle; one or more receiving circuit units (14) for detecting the signal level of the reflected wave received by the transmission/receiving units; one or more object detection units (16) for detecting an object on the basis of a comparison between an object detection threshold and the signal level detected by the receiving circuit units; one or more sensor-temperature detection units (17) for detecting the atmospheric temperature of the transmission/receiving units; and detection-sensitivity adjustment units (13, 22, 122) for adjusting detection sensitivity by adjusting the detection sensitivity of the receiving circuit units and/or the object detection threshold, on the basis of the atmospheric temperature detected by the sensor temperature detection units.
