Claim 0:
1. A control device for an object detection device, the control device comprising:
an object detector to output, to an ultrasonic transmitter, an input signal for causing the ultrasonic transmitter to transmit an object detection ultrasonic wave that is an ultrasonic wave transmitted for object detection, to obtain, from an ultrasonic receiver, an output signal in a period in which the object detection ultrasonic wave is reflected by an object around the ultrasonic transmitter and received as a reflected wave by the ultrasonic receiver, to determine whether the output signal includes a signal of the reflected wave, and to detect the object;
an abnormality detector to perform, as an abnormality detection process, outputting, to the ultrasonic transmitter, an input signal for causing the ultrasonic transmitter to transmit an abnormality detection ultrasonic wave that is an ultrasonic wave whose transmission time is longer than that of the object detection ultrasonic wave, obtaining, from the ultrasonic receiver, an abnormality detection output signal that is an output signal in a period in which the abnormality detection ultrasonic wave is to be received as a direct wave by the ultrasonic receiver, determining whether the abnormality detection output signal includes a signal of the direct wave, and detecting an abnormality in the ultrasonic transmitter or the ultrasonic receiver when no signal of the direct wave is included; and
a determiner to obtain speed information indicating a speed of a vehicle during driving provided with the ultrasonic transmitter and the ultrasonic receiver, determine whether the speed indicated by the speed information is not greater than a second threshold that is a predetermined positive threshold, and when a vehicle stop condition that the speed indicated by the speed information is not greater than the second threshold is satisfied, cause the abnormality detector to start the abnormality detection process.
