Description
自動変速機の制御装置であって、
前記自動変速機は、
トルクコンバータを介して駆動源から駆動力が入力される入力軸と、
出力部材と、
前記入力軸に入力された駆動力を前記出力部材に伝達する複数の遊星歯車機構と、
前記複数の遊星歯車機構における駆動力の伝達経路を切り替えて複数の変速段を確立可能な複数の係合機構と、を含み、
前記複数の係合機構のうちの一つは、ブレーキとして機能する機械式係合機構であり、
前記機械式係合機構は、
前記複数の遊星歯車機構が備える複数の回転要素のうちの所定の回転要素の第一の方向の回転のみ規制する第一の状態と、前記所定の回転要素の前記第一の方向及び前記第一の方向とは逆の第二の方向の双方向の回転を規制する第二の状態と、に切り替え可能であり、
前記複数の変速段は、
前記機械式係合機構が前記第一の状態及び前記第二の状態のいずれでも確立可能な前進最低速段と、
前記前進最低速段よりも変速比が高く、前記機械式係合機構が前記第二の状態では確立不能な前進段と、
前記機械式係合機構が前記第二の状態で確立する後進段と、を含み、
前記制御装置は、
変速段が前記前進最低速段であって、かつ、前記機械式係合機構が前記第二の状態の場合に、前記機械式係合機構を前記第一の状態に切り替えるか否かを判定する判定手段と、
前記判定手段の判定結果に基づいて前記機械式係合機構を前記第一の状態に切り替える切替処理手段と、を備え、
前記判定手段は、前記駆動力が規定駆動力よりも大きいことを少なくとも条件として、前記機械式係合機構を前記第一の状態に切り替えると判定し、
前記規定駆動力は、前記自動変速機の作動油の油温、前記自動変速機が搭載された車両の車速または前記車両が走行する走行路の下り勾配の少なくともいずれか一つに基づいて設定される、
ことを特徴とする制御装置が提供される。
図1は本発明の一実施形態に係る自動変速機1のスケルトン図である。図1を参照して、自動変速機1は、その変速機ケースを構成するケーシング12内に回転自在に軸支された入力軸10と、ケーシング12に支持された支持部材12aに、入力軸10と同軸回りに回転自在に支持された出力部材11と、出力軸(カウンタ軸)13と、を備える。
図4(A)は自動変速機1の制御装置100のブロック図である。制御装置100は自動変速機1だけでなく、内燃機関EGやトルクコンバータTCの各制御も行うことが可能であるが、本実施形態の場合、内燃機関EGは制御装置100とは別に設けたエンジンECU200により制御される構成を想定している。制御装置100はエンジンECU200から内燃機関EGや車両の各種情報を受信することができる。各種情報としては、内燃機関EGの駆動力(出力トルク)を挙げることができる。また、制御装置100は、自動変速機1の情報をエンジンECU200に送信することもできる。
ETR(%)=(入力軸回転数センサ112の検出回転数)/(入力回転数センサ111の検出回転数)×100
出力軸回転数センサ113は出力軸13の回転数(回転速度)を検出するセンサである。
本実施形態の場合、後進段ではブレーキF1が回転阻止状態である。前進段や非走行レンジから後進段に切り替える際、ブレーキF1を一方向回転許容状態から回転阻止状態に切り替える場合がある。この時、異音の発生や振動低減のため、ブレーキF1のケーシング12側と、キャリアCr2側との差回転数が0であることが好ましい。換言するとキャリアCr2の回転数が0であることが好ましい。
ブレーキF1は、機械的な駆動伝達を行う構成である。この種の係合機構の場合、内部の係合部に対する負荷の作用状態によって、状態の切り替えが円滑に行えない場合がある。この点を以下に説明する。
一速段の場合に、ブレーキF1をTWCからOWCに切り替える切替制御に関して処理部101が実行する処理例について図10を参照して説明する。
第一実施形態では車両が降坂走行であると判定した場合に、ブレーキF1をTWCからOWCへ切り替える例を説明した。本実施形態では、以下の切替準備制御により、ブレーキB3を係合することで、走行状態の制約をできるだけ少なくする。
本実施形態では、自動変速機1の構造上、変速段が一速段であって、かつ、ブレーキF1が一方向回転許容状態の場合に、ブレーキB3の係合によって、キャリアCr1、Cr2に作用するD2方向の負荷をブレーキB3に負担させることができる。
