Abstract：This studyaims todevelopanactive sound generation system for electric vehicles toenhance thecomfortand powel sensationof thein-carsoundduring aeleration.A design methodforin-carsound during acelerationis proposed，considering threeaspects：thecompositionofengineorders，thedistributionof spectralenergy，andtheenhancementofsoundamplitude withintypical speedranges.Basedonin-car sound surveys，subjectiveevaluations，and testresults，thesimulationanalysisof engine order sounds wascompleted.Anacoustic designscheme fortheaceleration scenario was establishedforacertain A-classpure electricSUV model，andanactive sound generation system based on the vehicle'saudio system was developed. The in-vehicle testresults show that theactive sound generation system increases thesound presureleveland loudness nside the vehicle，achieving amaximum reductionof1.Oacumin the sharpnessof the in-carsound.This activesound generation systemcanefectively improve thesoundqualityinsideelectricvehicles，providing reference for thesubjective evaluation calibration andactivecontrolmethodresearchof in-car sound qualityduring theacelerationconditionof electric vehicles.
