PARKING CONTROL DEVICE AND PARKING CONTROL METHOD

A parking control device includes a detector and a determiner. The detector receives, from an ultrasonic sensor which transmits an ultrasonic wave and receives a reflected wave corresponding to the ultrasonic wave, a signal based on the reflected wave. The detector further detects a detection point group being an aggregate of a plurality of detection points of two parked vehicle groups adjacent to a parking space between the two parked vehicle groups, based on the signal. The determiner determines whether the parking space is an end-on parking space or a parallel parking space based on a position of at least a depression shape in at least a contour pattern being a pattern of the detection point group.
