Zusammenfassung:	This position measurement method for a vehicle has: a process for determining whether position information for a device's own vehicle could be acquired from the outside at prescribed quality; a process for acquiring position information for a nearby vehicle present within an area in which acquisition of information for the device's own vehicle is possible, when the position information cannot be obtained at the prescribed quality; and a process for replacing the position information for the device's own vehicle with the acquired position information for the nearby vehicle.
