Description
本発明の実施の形態について、図1乃至図4を参照して説明する。なお、以下に説明する実施の形態は、本発明を実施する上での好適な具体例として示すものであり、技術的に好ましい種々の技術的事項を具体的に例示している部分もあるが、本発明の技術的範囲は、この具体的態様に限定されるものではない。
以上説明した実施の形態によれば、走行時に左右前輪11,12のうち何れか一方にスリップが発生し、駆動力伝達装置6を制御して左右後輪13,14に駆動力を伝達する際、駆動力伝達装置6によって左右後輪13,14に伝達される駆動力の立ち上がりを遅らせる遅延処理を行うので、例えば左前輪11にスリップが発生した際には、フロントディファレンシャル3の差動制限機能によって右前輪12のトラクションを活かすことができる。これにより、旋回性を向上させることができ、左右前輪11,12の両方がスリップした場合には、後輪側にトルクを伝達させるので走破性も向上する。
以上、本発明を実施の形態に基づいて説明したが、これらの実施の形態は特許請求の範囲に係る発明を限定するものではない。また、実施の形態の中で説明した特徴の組合せの全てが発明の課題を解決するための手段に必須であるとは限らない点に留意すべきである。
13,14…左右後輪(補助駆動輪) 15…エンジン(駆動源)
2…駆動力伝達系 3…フロントディファレンシャル(差動装置)
5…プロペラシャフト 6…駆動力伝達装置
7…制御装置
Claims (2)
- 左右の主駆動輪及び左右の補助駆動輪と、駆動源の駆動力を前記左右の主駆動輪に常時伝達すると共に車両状態に応じて駆動力を前記左右の補助駆動輪に伝達する駆動力伝達系とを備えた四輪駆動車であって、
前記駆動力伝達系は、前記左右の主駆動輪に駆動力を配分する差動装置と、車両前後方向に駆動力を伝達するプロペラシャフトと、前記プロペラシャフトから前記左右の補助駆動輪に伝達される駆動力を調節可能な駆動力伝達装置と、前記駆動力伝達装置を制御する制御装置とを備え、
前記差動装置は、前記左右の主駆動輪の差動を制限する差動制限力を発生することが可能な差動制限機能を有し、
前記制御装置は、前記左右の主駆動輪のうち何れかにスリップが発生し、前記駆動力伝達装置を制御して前記左右の補助駆動輪に駆動力を伝達する際、前記駆動力伝達装置によって駆動力の立ち上がりを遅らせる遅延処理を行い、
前記遅延処理は、前記左右の主駆動輪のうちスリップ比が低い方の車輪のスリップ比に基づいて前記駆動力伝達装置によって伝達される駆動力の指令値を演算する処理である、
四輪駆動車。 - 前記遅延処理は、前記左右の主駆動輪のスリップ比の差を演算し、当該差に対してローパスフィルタ処理を行い、当該ローパスフィルタ処理された前記差を前記左右の主駆動輪のうちスリップ比が低い方の車輪のスリップ比に加算し、当該加算された加算値に基づいて前記駆動力伝達装置によって伝達される駆動力の指令値を演算する処理である、
請求項1に記載の四輪駆動車。
