1. A user device, comprising:
- a storage device configured to store a program for a vehicular service;
a signal generation unit configured to generate a sound wave signal depending on the vehicular service;
a signal emission unit configured to emit the sound wave signal; and
a signal reception device configured to receive, from the vehicle, a feedback sound wave signal associated with the emitted sound wave signal,wherein when one component of the vehicle receives and recognizes the emitted sound wave signal, the vehicle provides the vehicular service based on the emitted sound wave signal,another component of the vehicle generates and emits the feedback sound wave signal in response to the emitted sound wave signal,the sound wave signal and feedback sound wave signal comprise a certain frequency corresponding to each of a plurality of symbols,the certain frequency is within an inaudible frequency band,the sound wave signal and the feedback sound wave signal are configured to control the user device or the vehicle to provide different vehicular services through the inaudible frequency band, andthe user device and the one component of the vehicle communicate with each other based on a sound wave communication.

Abstract
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.
