PARKING SUPPORT DEVICE, PARKING SUPPORT SYSTEM, AND PARKING SUPPORT METHOD

When having determined that an own-vehicle has become unable to proceed in a traveling direction corresponding to a travel path of the own-vehicle and has stopped halfway through a travel path, a parking support device transmits information to an operation terminal, the information indicating a travel path and a place at which the vehicle has stopped on the travel path. When having received, from the operation terminal, specification information specifying a place to which the own-vehicle is to be moved, the parking support device sets, as a travel path of the own-vehicle, a path through which the own-vehicle is to be moved to the specified place, and outputs, to a vehicle control unit, control information for causing the own-vehicle to move to the specified place.
