【解決手段】リレー装置1は、第1蓄電部91と第2蓄電部92との間で流れる電流の経路となる導電路11と、導電路22を通電させるオン状態と導電路22を所定の非通電状態にするオフ状態とに切り替わるスイッチ部20と、スイッチ部20を構成するMOSFET21,22と直列に接続され、インダクタンス成分を有するコイル30(インダクタンス部)と、電流検出部50による検出値が所定の異常値である場合にスイッチ部20をオフ状態に切り替える制御部3とを有する。

Description
第1蓄電部と第2蓄電部との間で流れる電流の経路となる導電路と、
前記導電路に接続され、前記導電路を通電させるオン状態と前記導電路を所定の非通電状態にするオフ状態とに切り替わるスイッチ部と、
前記スイッチ部と直列に接続され、インダクタンス成分を有するインダクタンス部と、
前記導電路の電流を検出する検出部と、
少なくとも前記検出部による検出値が所定の異常値である場合に前記スイッチ部をオフ動作させる制御部と、
を有する。
以下、本発明を具体化した実施例1について説明する。
図1で示す車載電源システム100は、複数の電源(第1蓄電部91及び第2蓄電部92)を備えた車載用の電源システムとして構成されている。リレー装置1は、車載電源システム100の一部をなしており、第1蓄電部91(メインバッテリ)と第2蓄電部92(サブバッテリ)との間を通電状態と非通電状態とに切り替える機能を有する。
リレー装置1では、制御部3によって各スイッチ部20(具体的には、各分離リレー5にそれぞれ設けられたMOSFET21,22の組)のオンオフが制御される。制御部3は、所定のオン条件が成立している場合、全ての分離リレー5に設けられたMOSFET21,22の組を全てオン状態に制御する。このようにオン状態に制御されているときには第1蓄電部91と第2蓄電部92の間が導通する。制御部3が複数のスイッチ部20をオン状態に制御するタイミングは特に限定されない。例えば、制御部3は、第2蓄電部92の出力電圧を継続的に監視し、第2蓄電部92の出力電圧が所定の電圧閾値未満に低下した場合に全ての分離リレー5に設けられた全てのスイッチ部20(MOSFET21,22)をオン状態に制御するように構成されていてもよい。つまり、第2蓄電部92の出力電圧が低下した場合に導電路11を導通状態に切り替え、発電機又は第1蓄電部91の電力によって第2蓄電部92を充電するように制御を行ってもよい。勿論、スイッチ部20をオン状態に制御する時期はこれ以外の時期であってもよい。
制御部3は、所定の異常状態が発生した場合、全ての分離リレー5に設けられた全てのスイッチ部20(MOSFET21,22)を強制的にオフ状態に制御する。具体的には、制御部3は、電流検出部50から入力される検出値(電流値)を継続的に監視しており、電流検出部50から入力される電流値が所定の電流閾値を超えた場合(即ち、導電路11が所定の過電流状態である場合)に全ての分離リレー5にそれぞれ設けられたMOSFET21,22の組を全てオフ状態に切り替える制御を行う。
本発明は上記記述及び図面によって説明した実施例に限定されるものではなく、例えば次のような実施例も本発明の技術的範囲に含まれる。
(1)実施例1では、メイン負荷81及びサブ負荷82として冗長性が求められるアクチュエータ(例えば電動パワーステアリングシステム)を例示したが、これ以外の例であってもよい。例えば、メイン負荷81が、レーダ、超音波センサ、カメラ等のセンシング装置として構成され、サブ負荷82がこれと同等の機能を有するバックアップ用のセンシング装置として構成されていてもよい。また、第1蓄電部91側に接続される負荷と、第2蓄電部92側に接続される負荷とが異なる機能を有していてもよい。
(2)実施例1では、分離リレー5の数が3である例を示したが、分離リレー5の数は、1であってもよく、3以外の複数であってもよい。
(3)実施例1では、分離リレー5に配置されるスイッチ部20が2つのMOSFET21,22によって構成された例を示したが、スイッチ部20は、MOSFET以外の半導体スイッチで構成されていてもよい。また、分離リレー5は、2つの半導体スイッチ素子をコイル30と直列に配置する構成に限定されず、1つの半導体スイッチ素子がコイル30と直列に接続されていてもよく、3以上の半導体スイッチ素子がコイル30と直列に接続されていてもよい。また、スイッチ部20は、機械式のリレーであってもよい。
