Abstract
Description
しかしながら、上述した電動パーキングブレーキにあっては、作動スイッチがオン状態で固着(オン固着と称する)すると、ウェイクアップ信号がハイレベルに固定され、電動パーキングブレーキ用のECUを動作停止(スリープ)状態にできない虞がある。
この問題は、電動パーキングブレーキに限らず、車載ネットワークで接続された複数のECUを備える車両用制御装置において、電装品の作動スイッチがオン状態で固着すると発生する。
図1は、車両用制御装置の概略構成図である。図1では、制御対象の電装品として電動パーキングブレーキを例に取り、これを制御するECUとその周辺部を抽出して示している。この車両用制御装置は、車載ネットワーク用のCANバス1a,1bを介して相互に接続された複数のECU(制御装置)2-1,2-2,2-3,2-4,…を備えている。ECU2-1は、電動パーキングブレーキ3用であり、電動パーキングブレーキ3の制動と解除を行うアクチュエータ4の駆動を制御する。
ここで、オン固着が続くとワーニングランプが点灯し続け、消費電流が増加するので、イグニッションオフ時に一定回数、または一定時間固着が継続した場合には、ECU2-1内の記憶装置(図示せず)に故障記録を残した上でワーニングランプを消灯するようにしても良い。
すなわち、CANなどの車載ネットワークで接続された複数のECUを備える車両用制御装置において、特定のECUで制御される電装品の作動スイッチがオン固着し、且つイグニッションキーがオフの場合に、当該ECUから他のECUへのデータ送信を停止させる。あるいは当該ECUを受信限定モードに設定する。
