VEHICLE APPROACH ALERT DEVICE

摘要

A vehicle approach alert device includes: a first sounding signal generation unit (220a) that generates a first sounding signal (Sa) based on first sound source data (210a); and a second sounding signal generation unit (220b) that generates a second sounding signal (Sb) based on second sound source data (210b); and a combining unit (23) that generates an alert sound signal by combining the first sounding signal and the second sounding signal. The first sounding signal generation unit varies the frequency and output level of the first sounding signal in accordance with a vehicle speed of the vehicle. The second sounding signal generation unit varies the output level of the second sounding signal in accordance with the vehicle speed of the vehicle while maintaining a constant frequency of the second sounding signal.
