Abstract
A sound generation apparatus for an electrification vehicle and a method of use thereof are provided. In example embodiments, the sound generation apparatus receives driving information, determines a driving situation based on the driving information, designs an acceleration sound when the driving situation is determined as an acceleration situation, or designs a cornering sound when the driving situation is determined as a cornering situation, and plays and outputs the acceleration sound or the cornering sound.
Claims18
A method of generating sound in an electrification vehicle, the method comprising:
- receiving, by a processing device, driving information;
- determining, by the processing device, a driving situation based on the driving information;
- designing, by the processing device, an acceleration sound, when the driving situation is determined as an acceleration situation;
- designing, by the processing device, a cornering sound, when the driving situation is determined as a cornering situation;
- and
- playing and outputting, by the processing device, the acceleration sound or the cornering sound,
- wherein designing the acceleration sound comprises:
- generating, by the processing device, a post-combustion signal based on the driving information;
- and
- converting, by the processing device, the generated post-combustion signal into the acceleration sound,
- wherein designing the cornering sound comprises:
- calculating, by the processing device, a cornering force based on the driving information;
- generating, by the processing device, the cornering sound based on the calculated cornering force;
- and
- adjusting, by the processing device, a tone and volume of the generated cornering sound.
A sound generation apparatus of an electrification vehicle, the sound generation apparatus comprising:
- a detection device configured to detect driving information;
- and
- a processing device connected to the detection device,
- wherein the processing device is configured to:
- determine a driving situation based on the driving information;
- design an acceleration sound, when the driving situation is determined as an acceleration situation;
- generate a post-combustion signal based on the driving information;
- convert the generated post-combustion signal into the acceleration sound;
- design a cornering sound, when the driving situation is determined as a cornering situation;
- and
- play and output the acceleration sound or the cornering sound,
- wherein the processing device is configured to:
- calculate a cornering force based on the driving information;
- generate the cornering sound based on the calculated cornering force;
- and adjust a tone and volume of the generated cornering sound.
