Claims (3)
- 電力変換回路を介して直流電源及び回転機関の電力交換がなされる電気系統であって且つ車体と電気的に絶縁される電気系統と、前記電気系統にコンデンサを介して接続されて且つ前記直流電源の電圧よりも低い電圧の振幅値からなる交流信号を出力する交流信号出力手段とを備える車載システムに適用され、前記交流信号出力手段が前記コンデンサに出力された前記交流信号の振幅の大きさに基づき、前記電気系統と前記車体との絶縁不良を検出する絶縁不良検出装置において、
前記電気系統からのノイズが前記交流信号に重畳されることによって前記検出の精度が低下することがない前記電気系統の安定状態にあると想定される車両が低負荷走行中であるとき、前記交流信号出力手段により前記交流信号を選択的に出力させる出力指令手段を備えることを特徴とする絶縁不良検出装置。 - 前記車載システムは、ナビゲーションシステムを備え、
前記出力指令手段は、前記ナビゲーションシステムからの情報に基づき、車両が低負荷走行中であるか否かを判断することを特徴とする請求項1記載の絶縁不良検出装置。 - 電力変換回路を介して直流電源及び回転機関の電力交換がなされる電気系統であって且つ車体と電気的に絶縁される電気系統と、前記電気系統にコンデンサを介して接続されて且つ前記直流電源の電圧よりも低い電圧の振幅値からなる交流信号を出力する交流信号出力手段とを備える車載システムに適用され、前記交流信号出力手段が前記コンデンサに出力された前記交流信号の振幅の大きさに基づき、前記電気系統と前記車体との絶縁不良を検出する絶縁不良検出装置において、
前記交流信号による前記車載システムへのノイズの影響を排除することが望まれる条件下において、前記交流信号出力手段による前記交流信号の出力を停止する停止手段を備えることを特徴とする絶縁不良検出装置。
