Description
まず、図1を参照して第1実施形態の電源装置の構成について説明する。
Claims (7)
- 入力電圧と出力電圧が所定の関係を有し、入力電圧が変化すると出力電圧も変化する直流電源回路(10)と、
前記直流電源回路に接続され、前記直流電源回路の出力電圧が正常出力電圧範囲にある場合、前記直流電源回路が正常であると判定する判定回路(11)と、
を備えた電源装置において、
前記判定回路は、前記直流電源回路の出力電圧が前記正常出力電圧範囲を除いた範囲にあり、かつ、前記直流電源回路の入力電圧と出力電圧が前記所定の関係とは異なる関係を有している場合、前記直流電源回路が異常であると判定することを特徴とする電源装置。 - 前記直流電源回路は、入力電圧が低下すると出力電圧が低下し、入力電圧が上昇すると出力電圧が上昇することを特徴とする請求項1に記載の電源装置。
- 前記直流電源回路は、出力電圧を所定数倍した電圧から入力電圧を引いた差分電圧が所定の差分電圧範囲になるように入力電圧を変換して出力し、
前記判定回路は、前記直流電源回路の出力電圧が前記正常出力電圧範囲を除いた範囲にあり、かつ、前記直流電源回路の前記差分電圧が前記所定の差分電圧範囲を除いた範囲にある場合、前記直流電源回路が異常であると判定することを特徴とする請求項2に記載の電源装置。 - 前記判定回路は、前記直流電源回路の出力電圧が前記正常出力電圧範囲より低圧側の領域及び高圧側の領域に設定された、前記直流電源が正常な場合には出力されることがない異常出力電圧範囲にある場合、前記直流電源回路が異常であると判定することを特徴とする請求項1〜3のいずれか1項に記載の電源装置。
- 前記判定回路は、前記直流電源回路が異常であると判定した場合、前記直流電源回路を再起動させることを特徴とする請求項1〜4のいずれか1項に記載の電源装置。
- 前記判定回路は、所定回数連続して前記直流電源回路が異常であると判定した場合、前記直流電源回路が故障していると判定することを特徴とする請求項1〜5のいずれか1項に記載の電源装置。
- 車両に搭載され、乗員を検知するための乗員検知センサ(S1)に電圧を供給することを特徴とする請求項1〜6のいずれか1項に記載の電源装置。
