The invention relates to a method and an apparatus for controlling driving sound of an electric vehicle. A method of controlling an electric vehicle driving sound using a motor vibration and a virtual transmission signal includes: extracting, by a signal processing controller, a vibration level of an Nth order component having a maximum linearity for a motor output torque among order components extracted from a vibration signal of a rotating electric vehicle (EV) motor and a virtual engine RPM; converting, by the signal processing controller, a revolution per minute (rpm) of the EV motor into a frequency to determine a frequency for each order component; the EV mode travel sound is set by the signal processor by applying a vibration level of the Nth order component to a frequency level of each order component to be output and rearranging the order components such that a number of revolutions per minute of the virtual engine reflects a travel mode changed according to the number of virtual gears.

    本公开涉及控制电动车辆的行驶声音的方法和装置。一种使用电动机振动和虚拟传动信号控制电动车辆行驶声音的方法,包括:由信号处理控制器提取从旋转电动车辆(EV)电动机的振动信号和虚拟发动机RPM提取的阶分量中的用于电动机输出扭矩的具有最大线性度的第N阶分量的振动电平;由信号处理控制器将EV电动机的每分钟转数(rpm)变换为频率,来确定每个阶分量的频率;由信号处理器通过将第N阶分量的振动电平应用于将被输出的每个阶分量的频率电平并且重排阶分量使得虚拟发动机的每分钟转数反映根据虚拟档位数变换的行驶模式,来设置EV模式行驶声音。
