Abstract
Disclosed is a sound design method for overcoming sense of difference when there is no virtual sound while an auto cruise control is activated. The method includes determining whether an accelerator pedal is actuated; upon determining that the accelerator pedal is not actuated, determining whether an auto cruise control system is operating; upon determining whether the auto cruise control system is operating, classifying a vehicle speed-based order component from a driving sound; and reproducing a speed sensitive virtual sound based on the classified vehicle speed-based order component.
Claims11
A method for generating a sound for a vehicle, the method comprising:
- determining whether an accelerator pedal is actuated;
- upon determining that the accelerator pedal is not actuated, determining whether an auto cruise control system is operating;
- upon determining whether the auto cruise control system is operating, classifying a vehicle speed-based order component from a driving sound;
- and
- reproducing a speed sensitive virtual sound based on the classified vehicle speed-based order component,
- wherein the classifying of the vehicle speed-based order component comprises analyzing a colormap of the driving sound using a deep learning-based colormap sound quality analysis algorithm and classifying the analysis result into order components of three levels.
A device for generating a sound for a vehicle, the device comprising:
- a detector for detecting whether an accelerator pedal is actuated and whether an auto cruise control system is operating;
- and
- a processor configured to:
- upon detection that the auto cruise control system is operating while the accelerator pedal is not actuated, classify a vehicle speed-based order component from a driving sound;
- and
- reproduce a speed sensitive virtual sound based on the classified vehicle speed-based order component;
- wherein classifying the vehicle speed-based order component comprises analyzing a colormap of the driving sound using a deep learning-based colormap sound quality analysis algorithm and classifying the analysis result into order components of three levels.
