A control device includes: an object detector to output a signal for causing a transmitter to transmit an object detection ultrasonic wave, obtain an output signal from a receiver, and detect an object; an abnormality detector to perform, as an abnormality detection process, outputting a signal for causing the transmitter to transmit an abnormality detection ultrasonic wave whose transmission time is longer than that of the object detection ultrasonic wave, obtaining, from the receiver, an output signal in a period in which the abnormality detection ultrasonic wave is to be received as a direct wave, and detecting an abnormality in the transmitter or receiver when no signal of the direct wave is included; and a determiner to obtain a speed of a vehicle including the transmitter and receiver, and when the speed is not greater than a threshold, cause the abnormality detector to start the abnormality detection process.
