Title:
VEHICLE APPROACH ALERT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/184829
Kind Code:
A1
Abstract:
A vehicle approach alert device includes a microcomputer (21) including a memory device (21a) in which approach alert sound data is stored, and a signal generation unit (21b) that generates an approach alert sound voltage waveform signal on the basis of the approach alert sound data. A sound generator (3) generates vehicle approach alert sound on the basis of the approach alert sound voltage waveform signal, alerting the approach of a vehicle. The microcomputer (21) includes an acquisition device (21c) that acquires a sound generator temperature, and a sound pressure correction device (21d) that implements correction such that the voltage level of the approach alert sound voltage waveform signal is increased as the sound generator temperature increases.
