Abstract

A user may freely generate a vehicle driving sound using a mounted mobile terminal so as to generate various types of driving sounds through a speaker. A vehicle includes a setting unit configured to set response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information and set a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including revolutions per minute (RPM) and a controller configured to control an output of the vehicle driving sound generated according to a setting of the setting unit and control sound transfer characteristics unique to the vehicle to be reflected when the vehicle driving sound is generated and output.

First claim

What is claimed is:

1. A vehicle comprising:
a setting unit configured to set response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information and set a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including revolutions per minute (RPM); and
a controller configured to control an output of the vehicle driving sound generated according to a setting of the setting unit and control characteristics of a sound-specific frequency distribution of an internal space of the vehicle to be reflected when the vehicle driving sound is generated and output.

2. The vehicle according to claim 1 , wherein the plurality of pieces of vehicle state information include at least one of accelerator pedal sensitivity, torque, a speed, and a transmission gear stage of the vehicle.

3. The vehicle according to claim 1 , wherein the setting of the section-specific volume of the vehicle driving sound includes setting a volume of a target driving sound through adding and offsetting for an actual engine sound according to each section.

4. The vehicle according to claim 1 , wherein the characteristics are characteristics of a driving sound transfer time according to a plurality of positions within a boarding space and a relative position of a speaker from which the vehicle driving sound is output.

5. The vehicle according to claim 1 , wherein the characteristics are synchronization characteristics of an output timing of each of a plurality of speakers from which the vehicle driving sound is output.

6. The vehicle according to claim 1 , wherein the setting unit is at least one of a head unit and a mobile terminal.

7. A control method of a vehicle comprising:
setting response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information;
setting a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including revolutions per minute (RPM); and
controlling an output of the vehicle driving sound generated according to the setting of a setting unit and controlling characteristics of a sound-specific frequency distribution of an internal space of the vehicle to be reflected when the vehicle driving sound is generated and output.

8. The control method of the vehicle according to claim 7 , wherein the plurality of pieces of vehicle state information include at least one of accelerator pedal sensitivity, torque, a speed, and a transmission gear stage.

9. The control method of the vehicle according to claim 7 , wherein the setting of the section-specific volume of the vehicle driving sound includes setting a volume of a target driving sound through adding and offsetting for an actual engine sound according to each section.

10. The control method of the vehicle according to claim 7 , wherein the characteristics are characteristics of a driving sound transfer time according to a plurality of positions within a boarding space and a relative position of a speaker from which the vehicle driving sound is output.

11. The control method of the vehicle according to claim 7 , wherein the characteristics are synchronization characteristics of an output timing of each of a plurality of speakers from which the vehicle driving sound is output.

12. The control method of the vehicle according to claim 7 , wherein the setting unit is at least one of a head unit and a mobile terminal.

13. A vehicle driving sound control apparatus comprising:
a setting unit configured to set response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information and set a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including RPM; and
a controller configured to control an output of the vehicle driving sound generated according to a setting of the setting unit and control characteristics of a sound-specific frequency distribution of an internal space of the vehicle to be reflected when the vehicle driving sound is generated and output.

14. A vehicle comprising:
a setting unit configured to set response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information including accelerator pedal sensitivity, torque, a speed, and a transmission gear stage of the vehicle and set a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including RPM; and
a controller configured to control an output of the vehicle driving sound generated according to a setting of the setting unit and control characteristics of a sound-specific frequency distribution of an internal space of the vehicle to be reflected when the vehicle driving sound is generated and output.
