Description

Electric Vehicle and Method of Controlling the Same The present invention relates to an electric vehicle and a control method thereof that manages the State of Charge (SOC) of a battery for the smooth operation of an acoustic control function. Recently, sound control functions such as the output of sound guidance and the input of voice commands are being actively applied to vehicles, such as inputting a destination into the navigation system using the driver's voice and outputting turn-by-turn guidance as voice during route guidance. Due to the nature of these sound control functions, which output sound and receive voice commands, ambient noise can affect their operational performance. For example, if ambient noise interferes while sound guidance is being output, vehicle users, such as drivers, may have difficulty recognizing the content of the guidance; conversely, if ambient noise interferes while a user is inputting a voice command, the noise may act as interference, potentially preventing the command from being accurately entered. Therefore, to ensure the smooth operation of the sound control function, various methods for controlling ambient noise can be applied. For example, in the case of electrified vehicles such as hybrid vehicles or electric vehicles, the performance of the acoustic control function may involve control to reduce ambient noise by adjusting the operating point of the power source or the driving mode according to the power source. However, since the battery's SOC can act as a constraint on such ambient noise reduction control, it is necessary to ensure that the battery's SOC is sufficiently secured prior to the control in order for the ambient noise reduction control to be performed smoothly when executing the acoustic control function.
