- モータによって駆動される車輪ブレーキ機構を有する電動駐車ブレーキを備えた車両に適用される制動制御装置であって、
前記モータに入力される電流値の目標である目標モータ電流値と、前記モータに入力される電流を検出する電流センサの検出値と、に基づき、前記電流センサの検出値が前記目標モータ電流値となるように前記モータに入力される電流を制御するモータ電流制御を実行する制御部と、
前記電流センサの検出値のオフセットの推定値であるオフセット推定値を、停車時のロック制御後の前記車両の挙動に基づいて決定するオフセット推定部と、
前記オフセット推定値に基づいて、前記目標モータ電流値または前記電流センサの検出値を補正するオフセット補正部と、を備え、
前記モータ電流制御の実行の完了に応じて前記車両が坂路に停車した場合、前記オフセット推定部は、当該停車から所定時間の間における前記車両の車輪速の変動度合が大きいほど、前記オフセット推定値を大きく決定し、
前記オフセット推定部によって決定された前記オフセット推定値が所定値以上の場合、前記オフセット補正部は、所定の上限値に基づいて前記目標モータ電流値または前記電流センサの検出値を補正する、制動制御装置。 - モータによって駆動される車輪ブレーキ機構を有する電動駐車ブレーキを備えた車両に適用される制動制御装置であって、
前記モータに入力される電流値の目標である目標モータ電流値と、前記モータに入力される電流を検出する電流センサの検出値と、に基づき、前記電流センサの検出値が前記目標モータ電流値となるように前記モータに入力される電流を制御するモータ電流制御を実行する制御部と、
前記電流センサの検出値のオフセットの推定値であるオフセット推定値を、停車時のロック制御後の前記車両の挙動に基づいて決定するオフセット推定部と、
前記オフセット推定値に基づいて、前記目標モータ電流値または前記電流センサの検出値を補正するオフセット補正部と、を備え、
前記モータ電流制御の実行の完了に応じて前記車両が坂路に停車した場合、前記オフセット推定部は、当該停車から所定時間の間における前記車両の車輪速の変動度合が大きいほど、前記オフセット推定値を大きく決定し、
前記停車時のロック制御後に前記車両が動かない状況が所定期間以上となった場合に、前記オフセット補正部は、前記目標モータ電流値または前記電流センサの検出値を補正する量を低減させる、制動制御装置。 - 前記停車時において前記車輪ブレーキ機構の温度が所定温度以上である場合、前記オフセット補正部は、前記目標モータ電流値または前記電流センサの検出値の補正を制限する、請求項1または請求項2に記載の制動制御装置。
