Provided is a vehicle sound generation device capable of outputting a sound that enables a driver to perform an accurate accelerator operation when a vehicle is slowly accelerated and decelerated. The vehicle sound generation device (1) includes a sound control circuit (12) that sets a plurality of frequencies according to a number of motor revolutions and sound pressures to be applied to the plurality of frequencies and generates a sound signal representing a synthetic sound including the sounds of the plurality of frequencies to which the set sound pressures have been applied, a speaker (20) that outputs a sound according to the sound signal, generated by the sound control unit (12), and a travel situation estimation circuit (13) that estimates a travel situation in which the driver accelerates or decelerates a vehicle. The sound control circuit (12) generates the sound signal representing only the single sound of the frequency in a range from 400 Hz to 900 Hz among the sounds of the plurality of frequencies when the travel situation is estimated.

    提供车辆用声音生成装置,能够输出在车辆缓慢地加减速行驶的状况下驾驶员可进行准确的加速器操作的声音。车辆用声音生成装置(1)具有:声音控制部(12),设定与马达转速相应的多个频率以及分别适用于该多个频率的声压,并生成表示合成音的声音信号,该合成音包含分别适用了该设定的声压的多个频率的声音;以及扬声器(20),输出与声音控制部(12)生成的声音信号相应的声音,该车辆用声音生成装置还具有对驾驶员使车辆(2)缓慢地加减速那样的行驶状况进行推断的行驶状况推断部(13),声音控制部(12)在推断为该行驶状况的情况下,生成仅表示在多个频率的声音中频率属于400~900Hz范围的单一的声音的声音信号。
