<p>An alert sound control unit (10) for an approaching vehicle warning apparatus (100) generates a signal for an alert sound to be emitted outside an electric mobile object (200) from a sound generator (40) installed in the electric mobile object (200), in which at least some of driving power is produced by an electric motor, and is provided with: a behavior conversion process unit (21) that outputs a post-conversion accelerator position signal by converting an accelerator position signal (11) among vehicle information signals (1) of the electric mobile object (200) by temporal variation processing; and an alert sound signal generation process unit (3) that generates an alert sound signal by converting the pitch and volume of a phoneme signal produced from phonemes (31, 310) on the basis of the post-conversion accelerator position signal.</p> |
