    摘要: An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.

    摘要: A transmission and reception device is located at a predetermined height on a movable object and directed toward an outside. The transmission and reception device includes a transmission unit for repeatedly transmitting sensing waves at a predetermined interval and a reception unit for receiving reflective waves of the sensing waves from a detected object. A peak value detecting unit detects peak values of the received reflective waves and stores the detected peak values. A difference arithmetic unit calculates a difference in the detected peak values with movement of the movable object closer to the detected object. An object determination unit determines the detected object to be a near-road-surface obstacle, which is close to a road surface, when the difference is a negative value. The object determination unit determines the detected object to be an other obstacle than the near-road-surface obstacle when the difference is a positive value.
