Abstract: A vehicle approach warning apparatus for abnormality detection in various abnormal modes is provided. In the vehicle approach warning apparatus, a sound generator output from the microcomputer passes an AMP and HPF, and an output voltage corresponding to the sound generator output is applied to a speaker to emit vehicle approach sound. The vehicle approach warning apparatus includes a voltage sensor circuit and outputs a check usage output as the sound generator output at the abnormality detection. A single frequency output that is within a resonance frequency band of the speaker and that can be poorly reproduced by the speaker is used as the check usage output. The abnormality detection is performed based on whether an integration circuit voltage outputted from the voltage sensor circuit is within a voltage range being an abnormality determination threshold.
