Description
図1は、本実施形態にかかる車両接近通報装置を含む車両接近通報システムのブロック図である。この図を参照して、本実施形態にかかる車両用接近通報装置を含む車両接近通報システムについて説明する。
上記実施形態では、電流センサ回路23によってAMP22に供給される電流が過電流になっていることを検出し、過電流になっているときの処置の一例として、AMP22への電流供給を停止することで、スピーカ3への電圧印加を一時的に停止する場合を例に挙げた。これに対して、電流センサ回路23の検出結果を電圧センサ回路24の検出結果に合せて用いることもできる。すなわち、電流センサ回路23にて過電流が検出された場合、電圧センサ回路25が出力する積分回路電圧に基づいて異常が検出されていれば、スピーカ3への電圧印加を停止するようにしても良い。
