Description
[1]車両の駆動力となるトルクを発生する駆動源と、前記駆動源のトルクを主駆動輪及び補助駆動輪に伝達する駆動力伝達系と、前記駆動力伝達系に設けられ、凹部と凸部との係合により前記補助駆動輪側にトルクを伝達することが可能な噛み合いクラッチと、前記駆動力伝達系における前記噛み合いクラッチのトルク伝達方向上流側又は下流側に設けられ、前記補助駆動輪側に伝達されるトルクを調整可能な調整クラッチと、路面の摩擦係数に関連する指標値に基づいて、路面の摩擦係数が所定値よりも低いか否かを判定する判定手段と、前記判定手段により路面の摩擦係数が所定値よりも低いと判定されたとき、発進前に前記噛み合いクラッチの係合を行わせる第1の制御信号を発生し、発進時において前記主駆動輪にスリップが発生したとき、前記調整クラッチに前記補助駆動輪側に伝達されるトルクを増大させる第2の制御信号を発生する制御手段とを備えた四輪駆動車。
図1は四輪駆動車の構成例を示す概略図である。この四輪駆動車101は、図1に示すように、四輪駆動車101の駆動力となるトルクを発生する駆動源としてのエンジン102と、エンジン102の出力を変速するトランスミッション103と、一対の前輪104L,104Rと、一対の後輪105L,105Rと、エンジン102のトルクを前輪104L,104R及び後輪105L,105Rに伝達する駆動力伝達系106とを有している。前輪104L,104Rは、走行時にエンジン102のトルクが常に伝達される主駆動輪の一例であり、後輪105L,105Rは、走行状態に応じて必要なトルクが伝達される補助駆動輪の一例である。
[他の実施の形態]
以上、本発明の四輪駆動車を上記の実施の形態に基づいて説明したが、本発明は上記の実施の形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の態様において実施することが可能であり、例えば次に示すような変形も可能である。
