Apparatus and method for generating sound of electrification vehicle

Abstract

An apparatus and a method for generating a sound of an electrification vehicle are provided. The apparatus comprises a detection device configured to detect state information of a vehicle, a sound output device configured to play and output a virtual sound, and a processing device connected with the detection device and the sound output device. The processing device configured to detect a cornering state of the vehicle based on state information of the vehicle, analyze a longitudinal force, a lateral force, a tire slip ratio, and a tire slip angle according to the cornering state, calculate a cornering force based on the analyzed results, calculate a contact force based on a tire ground surface and road surface profile based on big data, generate a tire slip sound based on the cornering force and the contact force, and control the sound output device to play the tire slip sound.
