A user device includes a storage device that stores a program for a vehicular service, a signal generation unit that generates a certain sound wave signal depending on the vehicular service, and a signal emission unit that emits the generated sound wave signal. When one component of a vehicle receives and recognizes the emitted sound wave signal, the vehicle provides the vehicular service based on the emitted sound wave signal.
