- 車両に働く駆動力を制御する制御装置であって、
前記駆動力を制御する第1の制御手段と、
前記駆動力の制限を前記第1の制御手段に要求する第2の制御手段と、
を備え、
前記第2の制御手段は、
前記第1の制御手段から出力される前記駆動力を入力する入力部と、
前記車両の不安定状態を検出する検出部と、
前記駆動力の上限値である駆動力上限値を第1のモードで算出する算出部と、
を有し、
前記算出部は、前記検出部から前記車両の走行状態が不安定であることを表す信号を送られると、前記第1のモードで、デフォルト値よりも低い前記駆動力上限値の算出を開始し、
その後、前記駆動力上限値よりも前記駆動力が低い場合、かつ前記駆動力上限値と前記駆動力の差が閾値以上である場合、前記算出部は、前記駆動力上限値を前記デフォルト値まで戻し、その際に、前記第1のモードの算出を停止し、前記デフォルト値を得、又は、前記駆動力上限値を前記第1のモードの代わりに前記駆動力上限値を前記デフォルト値まで増加させるための第2のモードで算出する、制御装置。 - 前記駆動力上限値よりも前記駆動力が低い時かつ前記駆動力上限値と前記駆動力の前記差が前記閾値以上である時にカウント・アップするカウント値が所定の値に到達するまで、前記算出部は、前記第1のモードで前記駆動力上限値を算出し続け、前記カウント値が前記所定の値に到達した後、前記算出部は、前記駆動力上限値を前記デフォルト値に戻す、請求項1に記載の制御装置。
- 前記車両の走行状態が不安定である時、前記算出部は、ヨー・レート偏差が小さくなるように、前記第1のモードで前記駆動力上限値を算出する、請求項1に記載の制御装置。
- 前記第2の制御手段は、前記算出部によって前記第1のモードで算出された前記駆動力上限値に前記駆動力を一致させるように前記第1の制御手段に要求する、請求項3に記載の制御装置。
- 前記第1の制御手段は、前記駆動力として、主駆動輪駆動力及び副駆動輪駆動力を制御し、前記主駆動輪駆動力は、前輪駆動力及び後輪駆動力の一方であり、前記副駆動輪駆動力は、前記前輪駆動力及び前記後輪駆動力の他方であり、
前記第2の制御手段は、前記駆動力の制限として、前記副駆動輪駆動力の制限を要求し、前記算出部は、前記駆動力上限値として、前記副駆動輪駆動力の上限値である副駆動輪駆動力上限値を前記第1のモードで算出する、請求項1に記載の制御装置。 - 前記第1の制御手段は、駆動力制御手段であり、前記第2の制御手段は、車両挙動制御手段である、請求項1に記載の制御装置。
