In one example embodiment, a user device (100) includes a storage device (110) that stores a program for a vehicular service, a signal generation unit (150) that generates a certain sound wave signal depending on the vehicular service, and a signal emission unit (160) that emits the generated sound wave signal. When one component of a vehicle (200) receives and recognizes the emitted sound wave signal, the vehicle provides the vehicular service based on the emitted sound wave signal.
