Abstract
【解決手段】直流電源Dの電源電圧E0を降圧して電源参照電圧V1を出力する参照電圧発生器K1と、所定の基準電圧ERを出力する基準電圧発生器K2と、電源参照電圧V1を第1の電源電圧検出用電圧として伝送すると共に基準電圧ERを第2の電源電圧検出用電圧として伝送する伝送線路WHと、第1の電源電圧検出用電圧と第2の電源電圧検出用電圧とを差動増幅する差動増幅器K3と、第1、第2の電源電圧検出用電圧に基づいて電源電圧E0を検出すると共に伝送線路WHの異常を検出する異常検出手段Pとを具備する。
【選択図】図1
Description
しかしながら、浮動直流電源と電圧検出手段(制御ユニット)との間の配線異常(地絡、断線)があった場合、浮動直流電源の電源電圧を正確又は/及び確実に検出できない虞がある。浮動直流電源の電源電圧を正確又は/及び確実に検出するためには、上記電位Vab及びと電位Vcdのような電源電圧の検出に必要な電圧(電源電圧検出用電圧)の伝送線路の異常を検知する必要がある。
本実施形態に係る電源電圧検出装置(以下、本電源電圧検出装置という。)は、図1に示すように、参照電圧発生器K1、基準電圧発生器K2、ワイヤーハーネスWH(伝送線路)、差動増幅器K3、I/F回路K4、第1電圧供給回路K5、第2電圧供給回路K6及び演算装置P(異常検出手段)を具備する。
(1)上記実施形態では、差動増幅器K3の増幅度を1倍から所定量だけ小さく設定することにより、第1電線h1に断線が発生した場合の断線判定用電圧Vdを電源電圧E0の過電圧範囲に属するようにしたが、本発明はこれに限定されない。例えば演算装置P内で第1検出用電圧Voa及び第2検出用電圧Vobを1倍から所定量だけ小さな増幅度で差動増幅することにより断線判定用電圧Vdを演算してもよい。この場合には、差動増幅器K3の増幅度を規定する抵抗器の抵抗値のばらつきの影響を排除することができるので、第1電線h1の断線の有無をより正確に判定することが可能となる。
