Abstract: A vacant parking space detection apparatus according to the present disclosure includes a memory and a hardware processor coupled to the memory. The hardware processor is configured to: generate, for each of divided regions in a region around a vehicle, map information representing a presence probability of an object based on a detection result of a sensor for detecting an object present around the vehicle; define on the map information a plurality of first straight lines, whose intercepts differ from each other, with one or more angles to a straight advancing direction of the vehicle; and detect whether a vacant parking space is present at the angle based on a presence probability of an object assigned to the divided region belonging to each of the plurality of first straight lines.

Abstract: A vehicle surroundings monitoring device measures coordinates of an obstacle on a first coordinate system on the basis of a position of the vehicle at a first time point at which a transmission wave is output and a position of the vehicle at a second time point at which a reflected wave of the transmission wave is detected. The monitoring device writes, to a storage device, coordinates of the obstacle on a second coordinate system having a resolution lower than a resolution of the first coordinate system when power turn-off of the vehicle is detected. The monitoring device reads, from the storage device, the coordinates of the obstacle on the second coordinate system when power turn-on of the vehicle is detected. The monitoring device determines whether the vehicle and the obstacle come into contact with each other by using the coordinates of the obstacle read from the storage device.
