Abstract
【解決手段】四輪駆動車100は、エンジン102の駆動力を前輪104L,104Rに伝達する第1の駆動力伝達系106と、エンジン102の駆動力を後輪105L,105Rに伝達する第2の駆動力伝達系107と、イグニッションスイッチ101と、ECU9とを備え、第2の駆動力伝達系107は、噛み合いクラッチ130及び駆動力を連続的に調節可能な駆動力伝達装置160を有し、路面の摩擦係数に関する指標値に基づいて路面の摩擦係数が所定値以上か否かを判定する路面状態判定手段921を有し、イグニッションスイッチ101がオン状態となったとき、路面の摩擦係数に関する指標値にかかわらず噛み合いクラッチ130を連結状態に制御し、路面の摩擦係数が所定値以上であると判定したとき、噛み合いクラッチ130を解放状態に制御する。
【選択図】図4
Description
本実施の形態によれば、イグニッションスイッチ101がオン状態に操作されたとき、直ちに噛み合いクラッチ130が連結状態となるので、エンジン102の始動直後に四輪駆動車100が発進した場合でも、前輪104L,104Rにスリップが発生すれば、駆動力伝達装置160を制御することによって、速やかに後輪105L,105Rに駆動力を配分することが可能となる。つまり、仮に噛み合いクラッチ130が解放状態であるディスコネクトモードで四輪駆動車100が発進して前輪104L,104Rにスリップが発生した場合には、噛み合いクラッチ130を連結状態としなければ後輪105L,105Rに駆動力を配分することができないが、前輪104L,104Rがスリップしている場合には前後輪の回転差が大きく、噛み合いクラッチ130における第1の歯部31と第2の歯部32との回転が同期せず、スリーブ33によって第1の歯部31と第2の歯部32とを連結することができない。しかし、本実施の形態では、噛み合いクラッチ130の連結状態で発進することができるので、発進時におけるスリップを早期に収束させることが可能となる。
以上、本実施の形態を説明したが、本発明は上記した実施の形態に限定されることなく、その趣旨を逸脱しない範囲で適宜変形して実施することが可能である。例えば、上記実施の形態では、駆動力伝達系におけるプロペラシャフト140とフロントディファレンシャル120のデフケース20との間に噛み合いクラッチ130を配置し、リヤディファレンシャル150と左後輪105Lとの間に駆動力伝達装置160を配置したが、この配置は逆であってもよい。また、プロペラシャフト140とリヤディファレンシャル150との間に駆動力伝達装置160を配置してもよい。
