Definitions
- the present invention relates to an idle stop control device for a vehicle equipped with an automatic manual transmission, and more particularly to a technique for improving a restart response after the idle stop.
- an idle stop control device for a vehicle for example, a device as described in Patent Document 1 has been proposed.
- Any automatic manual transmission can automatically select the starting gear train by the automatic clutch release via the hydraulic oil from the pump driven by the engine, the engagement control, and the starting pre-shift control of the selective meshing mechanism.
- the vehicle can be started by outputting engine power via the starting gear train.
- the vehicle may be stopped before the start pre-shift control (deselecting the selected gear train and selecting the start gear train) is completed. is there. Even in the case of a slow stop with a small vehicle deceleration, the starting gear train selection operation of the starting pre-shift is not completed once due to poor synchronization or the like (the selection of the starting gear train is not completed once). If the vehicle is repeatedly executed, the vehicle may stop before the start preshift control is completed.
- the suspended start pre-shift is resumed after the driver performs a restart request operation and the engine is restarted in response to the operation and the hydraulic fluid is discharged from the pump. is there. Therefore, the engine is restarted in response to the restart request operation, and the restart of the clutch such as the automatic clutch is in progress until the start preshift restarted with hydraulic oil from the pump driven by the engine is completed. As a result, the control cannot be started, which causes a problem that the response delay in restarting increases.
- the present invention has a problem that the delay in the re-starting response becomes large if the engine pre-shift is completed after the start pre-shift is completed by including completion of the pre-start for automatic manual transmission in the idle stop permission condition. From the standpoint that it can be solved, an object of the present invention is to propose an idle stop control device for a vehicle equipped with an automatic manual transmission that embodies this idea, and to solve the above problems.
- the idle stop control device for a vehicle equipped with an automatic manual transmission is configured as follows.
- An idle stop type engine that is stopped when a predetermined idle stop permission condition including stopping is satisfied, and automatic clutch release, engagement control, and start of a selective meshing mechanism via a medium from a pump driven by the engine
- a vehicle equipped with an automatic manual transmission capable of automatically selecting a starting gear train by pre-shift control and enabling the vehicle to start by outputting the power of the engine via the automatically selected starting gear train It is an idle stop control apparatus to be used.
- the idle stop control device of the present invention is provided with a starting preshift completion determining means for determining whether or not the starting preshift control is completed when the vehicle stops. It is characterized in that the idle stop permission condition includes that it is determined that the starting pre-shift control is completed by the means.
- the idle stop is permitted only when the start preshift control is completed, and even if the vehicle stops before the start preshift control is completed, the idle stop control is performed. The engine will not be shut down.
- the start pre-shift control is completed when the engine is stopped due to idle stop. For this reason, when the engine is restarted in response to the restart request operation by the driver after the idle stop, the restart control such as the automatic clutch engagement progress is immediately started by the medium from the pump driven by the engine. It is possible to solve the conventional problem that the delay in the restart response after the idling stop increases, and to improve the restart response.

Abstract
Description
この提案技術は、発進意志のない停車状態のごとき所定のアイドルストップ許可条件(アクセル開度=0、ブレーキを作動させた制動状態、車速VSP=0)が成立したとき、エンジンを運転停止させ、これによりエンジンの燃費を向上させるというものである。
何れの自動マニュアルトランスミッションも、エンジンにより駆動されるポンプからの作動油を介した自動クラッチの解放、締結制御および選択噛合機構の発進用プリシフト制御により発進ギヤ列を自動選択可能で、該自動選択された発進ギヤ列を経由してエンジンの動力を出力することにより車両を発進させることができる。
この発進用プリシフトは具体的には、車両減速中に、現在選択中のギヤ列に係わる選択噛合機構の噛み合いを解除し(当該ギヤ列を非選択状態にし)、発進用ギヤ列の選択噛合機構を噛み合わせて(発進用ギヤ列を選択状態にして)、当該発進用のプリシフトを遂行する。
なお車両減速度の小さな緩停車の場合でも、上記発進用プリシフトの発進用ギヤ列選択作業が同期不良などにより1回で終わらず(1回で発進用ギヤ列の選択が終わらず)、当該作業を繰り返し実行することになると、発進用プリシフト制御が完了する前に車両が停車状態に至ってしまうことがある。
しかして自動マニュアルトランスミッションの発進用プリシフトはエンジン駆動されるポンプからの作動油で行われており、上記のごとく発進用プリシフトの完了前にアイドルストップ制御でエンジンが運転を停止されると、ポンプからの作動油が無くなることにより、発進用プリシフトが完了しないまま中断されてしまうことになる。
従って、再発進要求操作に呼応してエンジンが再始動され、このエンジンにより駆動されるポンプからの作動油で再開される発進用プリシフトが完了するまでの間、自動クラッチの締結進行などの再発進制御を開始できないこととなり、その分、再発進の応答遅れが大きくなるという問題を生ずる。
停車を含む所定のアイドルストップ許可条件が成立するとき運転を停止されるアイドルストップ式エンジンと、該エンジンにより駆動されるポンプからの媒体を介した自動クラッチの解放、締結制御および選択噛合機構の発進用プリシフト制御により発進ギヤ列を自動選択可能で、該自動選択された発進ギヤ列を経由して前記エンジンの動力を出力することで車両の発進を可能にする自動マニュアルトランスミッションとを具備した車両に用いるアイドルストップ制御装置である。
該手段により上記発進用プリシフト制御が完了しているとの判定がなされていることを上記アイドルストップ許可条件に含めるよう構成した点に特徴づけられるものである。
このため、アイドルストップ後の運転者による再発進要求操作に呼応してエンジンが再始動されたとき、エンジン駆動されるポンプからの媒体で直ちに自動クラッチの締結進行などの再発進制御を開始させることができ、アイドルストップ後の再発進応答遅れが大きくなるという従来の問題を解消し得て、再発進応答を向上させることが可能となる。

図1は、本発明の一実施例になるアイドルストップ制御装置を具えた自動マニュアルトランスミッション搭載車のパワートレーンおよびその制御系を示す。
1は、図2につき後述する自動マニュアルトランスミッションで、図の左端からエンジン2の回転を入力され、この入力回転を選択変速段(ギヤ列)に応じ変速して図の右端より車輪に向かわせ、これら車輪の駆動により車両を走行させるものである。
セレクトレバー3の操作位置には、自動マニュアルトランスミッション1を駐車(P)レンジにするPレンジ位置と、後退走行(R)レンジにするRレンジ位置と、中立(N)レンジにするNレンジ位置と、前進自動変速(D)レンジにするDレンジ位置とを設定する。
そのため自動MTコントローラ4には、車速VSPを検出する車速センサ5からの信号と、アクセル開度APOを検出するアクセル開度センサ6からの信号と、セレクトレバー3のレンジ位置P,R,N,Dを検出するレンジ位置センサ7からの信号と、ブレーキペダルの踏み込み時にONとなるブレーキスイッチ8からの信号と、各ギヤ列に係わる同期噛合機構(選択噛合機構)のシフト位置を検出するシフト位置センサ9からの信号とを入力する。
このためエンジンコントローラ10は、自動MTコントローラ4との間で、当該コントローラ4への上記入力信号を含めて情報を交換し合うものとする。
自動マニュアルトランスミッション1はツインクラッチ式自動マニュアルトランスミッションとして構成するが、このツインクラッチ式自動マニュアルトランスミッションおよびその自動変速制御システムは、特開2007-040407号公報におけると同じもので、本明細書においてはこれらの詳細説明を省略するが、自動変速作用は、エンジン2により駆動されるオイルポンプO/Pからのオイルを媒体とし、概略以下のように行われる。
この状態で、第1速の変速段グループに係わるクラッチCAを締結することで第1速伝動ギヤ列を実現し得る。
この1→2変速後、第3速用同期噛合機構(選択噛合機構)20のカップリングスリーブ21をシフトアクチュエータ22により図示の中立位置から左行させて第3速選択位置(3速シフトギヤイン終了位置)へシフト動作させることにより、第3速入力歯車23を対応する入力軸24に結合させて第3速伝動ギヤ列G3を選択する第3速へのプリシフトを行う。
この2→3変速後、第4速用同期噛合機構(選択噛合機構)16のカップリングスリーブ17をシフトアクチュエータ18により第2速選択位置(2速シフトギヤイン終了位置)から図示の中立位置に戻した後、更にこの中立位置から右行させて第4速選択位置(4速シフトギヤイン終了位置)へシフト動作させることにより、第4速出力歯車25をカウンターシャフト15に結合させて第4速伝動ギヤ列G4を選択する第4速へのプリシフトを行う。
第6速から順次第1速へダウンシフトさせるに際しても、アップシフトと逆のクラッチCA,CBの掛け替え制御および順次のプリシフトを行うことにより、所定のダウンシフト(伝動ギヤ列の切り替え)を行うことができる。
この状態で、後退変速段の変速段グループに係わるクラッチCAを締結することで後退伝動ギヤ列を実現し得る。
同期噛合機構のシフト位置検出に当たっては、シフト位置変化に連動する永久磁石と、その磁束を検出するセンサとから成る磁気結合型のシフト位置センサ(図2では、1-Rシフト位置センサのみに9の符号を付して示した)を用いる。
例えば前発進のため中立状態から第1速へのプリシフトを行うこととなった場合につき説明すると、
コントローラ4は、第1速用同期噛合機構(選択噛合機構)11のカップリングスリーブ12を図2に示す中立位置から左行させて第1速選択位置(1速シフトギヤイン終了位置)にシフト動作(プリシフト)させる電子制御指令を発する。
シフトアクチュエータ13はこの油圧に応動して、第1速用同期噛合機構(選択噛合機構)11のカップリングスリーブ12を第1速選択位置(1速シフトギヤイン終了位置)へシフト動作させることにより、要求通りのプリシフトを行うことができる。
このセンサ検出値が、第1速用同期噛合機構(選択噛合機構)11の第1速選択位置(1速シフトギヤイン終了位置)に対応した値になるとき、コントローラ4は、第1速用同期噛合機構(選択噛合機構)11が第1速選択位置(1速シフトギヤイン終了位置)に達してプリシフトが終了したとの判断により、シフトアクチュエータ13の上記作動油圧を零にする指令を発する。
コントローラ4は、後退用同期噛合機構(選択噛合機構)11のカップリングスリーブ12を図2に示す中立位置から右行させて後退選択位置(後退シフトギヤイン終了位置)にシフト動作(プリシフト)させる電子制御指令を発する。
シフトアクチュエータ13はこの油圧に応動して、後退用同期噛合機構(選択噛合機構)11のカップリングスリーブ12を後退選択位置(後退シフトギヤイン終了位置)へシフト動作させることにより、要求通りのプリシフトを行うことができる。
このセンサ検出値が、後退用同期噛合機構(選択噛合機構)11の後退選択位置(後退シフトギヤイン終了位置)に対応した値になるとき、コントローラ4は、後退用同期噛合機構(選択噛合機構)11が後退選択位置(後退シフトギヤイン終了位置)に達してプリシフトが終了したとの判断により、シフトアクチュエータ13の上記作動油圧を零にする指令を発する。
上記の自動マニュアルトランスミッション1を搭載した車両のエンジンアイドルストップ制御を以下に説明する。
このアイドルストップ制御の許可条件である停車に先立つ車両減速中、自動マニュアルトランスミッション1は停車後の再発進に備えて発進用プリシフトを行う。
具体的には、上記の車両減速中に、現在選択中のギヤ列に係わる自動クラッチCAまたはCBを解放して(これにより自動クラッチCAおよびCBは共に解放状態)、現在選択中のギヤ列に係わる選択噛合機構の噛み合いを解除する(当該ギヤ列を非選択状態にする)と共に、発進用ギヤ列(前進走行中なら第1速ギヤ列)の選択噛合機構11をカップリングスリーブ12の対応方向シフト(図2の左行)により噛み合わせ、発進用ギヤ列(第1速ギヤ列)が選択された状態にする。
従って、再発進要求操作が行われてから(エンジン2の再始動後に)再開される発進用プリシフトが完了するまでの間、自動クラッチCAの締結進行などの再発進制御を開始できないため、その分、再発進の応答遅れが大きくなるという問題を生ずる。
ステップS11においては、アイドルストップ許可条件の1つである車速VSP=0(停車状態)が成立しているか否かをチェックし、車速VSP=0(停車状態)でなければアイドルストップ制御が不要であるから、制御を元に戻して待機する。
従ってステップS12は、本発明における発進用プリシフト完了判定手段に相当する。
ステップS12で発進用プリシフトが完了していないと判定する間は、ステップS13において発進用プリシフトを継続させつつ、制御をステップS12に戻して待機する。
ステップS14で車速VSP=0(停車状態)以外のアイドルストップ許可条件が成立していないと判定する間は、アイドルストップ制御が不要であるから、制御を元に戻して待機し、これらアイドルストップ許可条件が成立したと判定するとき、ステップS15においてエンジン2を設定回転数未満になった時からアイドルストップ制御により運転停止させる。
ステップS21においては、アイドルストップ状態でエンジン再始動条件(例えば、ブレーキ操作解除によりブレーキスイッチ8がONからOFFになるなど)が成立したか否かをチェックし、エンジン再始動条件が成立するまでは制御を元に戻して待機する。
次のステップS23においては自動MTコントローラ4が、第1速ギヤ列G1に係わる発進クラッチCAを再発進用に締結進行制御する。
上記した本実施例のアイドルストップ制御によれば、ステップS12の追加により、発進用プリシフト(選択中のギヤ列の選択解除および第1速ギヤ列G1の選択)の完了をアイドルストップ許可条件に含めて、この発進用プリシフト(選択中のギヤ列の選択解除および第1速ギヤ列G1の選択)が完了した後にエンジン2のアイドルストップを行わせるようにしたため、以下のような効果を得ることができる。
制動開始時t0以降の車両減速中、所定の低車速になった瞬時t1から、ギヤ位置変化として示すように発進用プリシフト(選択中のギヤ列の選択解除および第1速ギヤ列G1の選択)が開始される。
発進用プリシフト(選択中のギヤ列の選択解除および第1速ギヤ列G1の選択)が完了する瞬時t3に、当該発進用プリシフトの完了と、停車を含む他のアイドルストップ許可条件とが成立したことで、アイドルストップ許可フラグFLAGaがONとなり、エンジン回転数Neが設定回転数未満になる瞬時t4にアイドルストップフラグFLAGbがONとなり、エンジン2はエンジン回転数Ne=0として示すように運転を停止される。
これによりエンジン回転数Neが設定回転数以上になった瞬時t6にアイドルストップフラグFLAGbがOFFとなり、エンジンアイドルストップ制御を終了する。
自動クラッチ指令油圧Pcは、瞬時t7~t8の間において発進クラッチCAを油圧充填(プリチャージ)より急速にロスストロークさせ、その後において発進クラッチCAを徐々に締結進行させるためのものである。
かように車両が発進を開始した瞬時t9に、車速VSP=0のアイドルストップ許可条件が消失したことで、アイドルストップ許可フラグFLAGaはOFFとなる。
瞬時t5での制動解除(ブレーキスイッチOFF)による再発進要求操作(ステップS21)に呼応したエンジン再始動後、発進クラッチCAの締結ストローク開始時t7までの間に、発進用プリシフト(選択中のギヤ列の選択解除および第1速ギヤ列G1の選択)を完遂させる処理が必要になることがなく、アイドルストップ後の再発進応答遅れが大きくなるという前記した従来の問題を解消し得て、再発進応答を向上させることができる。
アイドルストップ後の再発進に使わないギヤ列が当該再発進中に選択解除されていることとなり、当該ギヤ列が再発進に際してショックの原因となるのを防止することができる。
自動マニュアルトランスミッション1が、通常のマニュアルトランスミッションを自動変速可能に自動化したシングルクラッチ式自動マニュアルトランスミッションである場合も、本発明の前記した着想を適用して同様な作用効果を奏し得ることは言うまでもない。
