The present invention provides, inter alia, a sound signal generation device capable of generating a simulated engine sound signal representing an engine sound that provides a sensation connected to actually traveling on an electric vehicle even when no engine has been installed in the electric vehicle, for example.The present invention comprises: a virtual engine speed generation unit (100) that acquires accelerator position data (AC) indicating an acceleration operation amount for an electric vehicle, and travel speed data (SP) indicating the vehicle travel speed of the electric vehicle, calculates a virtual travel speed of a virtual engine vehicle, corrects the virtual travel speed on the basis of the travel speed data (SP), and calculates the engine speed of the virtual engine on the basis of the corrected virtual travel speed; and a simulated engine sound generation unit (101) that generates a sound signal for outputting a simulated engine sound, corresponding to a travel state of the electric vehicle, on the basis of the acceleration operation amount indicated by the travel speed data (SP) and the engine speed calculated by the virtual engine speed generation unit (100).

    提供例如即便是完全未搭载发动机的电动车,也能够虚拟地生成表示与该行驶联动的具有临场感的发动机的声音的发动机声音信号的声音信号生成装置等。具备:假想发动机转速生成部(100),取得表示电动车中的加速器操作量的加速器开度数据AC和表示电动车的车辆行驶速度的行驶速度数据SP,计算假想发动机车的假想行驶速度,基于行驶速度数据SP修正假想行驶速度,基于修正后的假想行驶速度来计算假想发动机的发动机转速;以及伪发动机声音生成部(101),基于行驶速度数据SP所表示的加速器操作量和由假想发动机转速生成部(100)计算出的发动机转速,生成用于发出与电动车的行驶状态对应的虚拟性的发动机声音的声音信号。
