- the amount of change in the rotational speed of the input shaft IS (the amount of decrease in the rotational speed) at the beginning of the operation is large, and the amount of change in the rotational speed of the input shaft IS just before the completion of this operation is small.

Conversely, when the gear stage is high (when the gear stage selected by operating the shift lever L is high; when the vehicle speed is a predetermined high speed stage), the driver makes a slow acceleration of the vehicle. It is presumed that the driver is driving as required. When the vehicle is traveling with a predetermined low gear position selected, it can be determined that the driver's travel orientation is sport mode travel orientation. Conversely, when the vehicle is traveling with a predetermined high gear selected, it can be determined that the driver's travel orientation is comfort mode travel orientation.

- (S-5) Shift speed change time by operating the shift lever L
- the shift speed switching time time required for the shift speed switching operation
- the shift time for the shift stage becomes longer. That is, when the shift stage switching time by the operation of the shift lever L is shorter than the predetermined time, it can be determined that the driving orientation of the driver is the sports mode driving orientation.

- the combination is not limited to 4), and other combinations may be used, and the driving orientation of the driver may be determined by combining three or more.
- execution conditions for such a shift lever operation determination operation include “the vehicle is in a warm-up completed state” and “the clutch device 6 is being operated”. The reason is that when the vehicle is not in the warm-up completed state, the viscosity of the lubricating oil inside the speed change mechanism is high, and the viscosity acts greatly as a resistance of the shift lever operation, and the driver's driving orientation is detected with high accuracy. For this reason, it is difficult for the vehicle to be warmed up. In addition, it is difficult to detect the driver's driving orientation with high accuracy even when the shifting operation is performed without operating the clutch device 6, so that the operation of the clutch device 6 is performed. This is an execution condition for the orientation determination operation.
- the inertia torque is a torque transmitted along with the reduction of the engine speed when the clutch device 6 is engaged. That is, when the engine torque is the same, the clutch torque increases as the inertia torque increases. For example, when the amount of depression of the accelerator pedal at the time of engagement of the clutch device 6 is large and the depression release speed of the clutch pedal 70 is high, the inertia torque per unit time increases, and as a result, the clutch torque also increases.
- Such a situation is a case where the driver has an intention to connect the clutch device 6 early (in a short time). Therefore, when the clutch torque is higher than a predetermined value (when the clutch torque is larger than the predetermined value with respect to the engine torque), it can be determined that the driver's driving intention is the sports mode driving intention. On the other hand, when the clutch torque is lower than a predetermined value (when the clutch torque is smaller than the predetermined value with respect to the engine torque), it can be determined that the driving direction of the driver is the comfort mode driving direction.
- These predetermined values are appropriately set by experiments or the like.

シフトレバー操作判定動作は、上述した如く、シフトレバーLの手動操作により走行志向を判定するものである。具体的には以下の情報(変速操作に応じて変化する操作情報)のうちの少なくとも一つを利用して走行志向が判定される。
(S-2)インプットシャフトISの回転数
(S-3)シフトレバーLの単位時間当たりの操作移動量
(S-4)シフトレバーLの操作により選択された変速段
(S-5)シフトレバーLの操作による変速段の切り換わり時間
(S-6)シフト荷重の大きさ
以下、それぞれについて具体的に説明する。
このインプットシャフトISの回転数の単位時間当たりの変化量は、上記シフトレバーLの手動操作によって変速機構の変速段が切り換えられた場合におけるインプットシャフトISの回転数(Ni:クラッチ装置6が継合される前段階におけるインプットシャフトISの回転数)の時間微分値(dNi/dt)により求められる。具体的には、上記インプット回転数センサ8Aによって検出されたインプットシャフトISの回転数を時間微分することにより求められる。つまり、運転者によるシフトレバーLの手動操作速度が高い場合には、比較的短時間のうちに変速段が切り換えられることからインプットシャフトISの回転数の単位時間当たりの変化量は大きくなる。逆に、運転者によるシフトレバーLの手動操作速度が低い場合には、変速段が切り換えられるまでに比較的長い時間を要することからインプットシャフトISの回転数の単位時間当たりの変化量は小さくなる。つまり、インプットシャフトISの回転数の単位時間当たりの変化量を算出することで、シフトレバーLの手動操作速度を判定することができる。
(a)変速開始から変速完了までの期間におけるインプットシャフトISの回転数の平均変化量は、変速開始から変速完了までに要する時間に相関がある。つまり、この期間におけるインプットシャフトISの回転数の平均変化量が大きい場合には、シフトレバーLの手動操作速度やシフト荷重が高く、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、この期間におけるインプットシャフトISの回転数の平均変化量が小さい場合には、シフトレバーLの手動操作速度やシフト荷重が低く、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。
車両速度が同一であれば変速段が低い(変速比が高い)ほど、インプットシャフトISの回転数(上記インプット回転数センサ8Aによって検出されたインプットシャフトISの回転数)は高くなる。このように車両速度が同一であっても変速段が低い場合には、運転者は、車両の急加速を要求するような走行志向で運転していると推測される。逆に、車両速度が同一であっても変速段が高い場合には、運転者は、車両の緩加速を要求するような走行志向で運転していると推測される。このため、インプットシャフトISの回転数が所定値よりも高い(低変速段が選択されて走行している;車両速度に対して、インプットシャフトISの回転数が所定値よりも高い)場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、インプットシャフトISの回転数が所定値よりも低い(高変速段が選択されて走行している;車両速度に対して、インプットシャフトISの回転数が所定値よりも低い)場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
シフトレバーLの単位時間当たりの操作移動量は、上記シフトレバーLの手動操作によって変速機構の変速段が切り換えられた場合におけるシフトレバーLの移動量(sfts)の時間微分値(dsfts/dt)により求められる。具体的には、上記セレクト操作方向位置センサ8C及びシフト操作方向位置センサ8Dによって検出されたシフトレバーLの移動量を時間微分することにより求められる。そして、シフトレバーLの単位時間当たりの操作移動量が所定値よりも大きい場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、シフトレバーLの単位時間当たりの操作移動量が所定値よりも小さい場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
車両速度が同一であっても変速段が低い場合(シフトレバーLの操作により選択された変速段が低い場合;車両速度に対して、所定の低速段である場合)には、運転者は、車両の急加速を要求するような走行志向で運転していると推測される。逆に、変速段が高い場合(シフトレバーLの操作により選択された変速段が高い場合;車両速度に対して、所定の高速段である場合)には、運転者は、車両の緩加速を要求するような走行志向で運転していると推測される。そして、所定の低変速段が選択されて走行している場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、所定の高変速段が選択されて走行している場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。
シフトレバーLの操作速度が高い場合には、変速段の切り換わり時間(変速段の切り換え操作に要する時間)は短く、逆に、シフトレバーLの操作速度が低い場合には、変速段の切り換わり時間は長くなる。つまり、シフトレバーLの操作による変速段の切り換わり時間が所定時間よりも短い場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、シフトレバーLの操作による変速段の切り換わり時間が所定時間よりも長い場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。
シフトレバーLの操作速度が高い場合にはシフト荷重は大きくなり、逆に、シフトレバーLの操作速度が低い場合にはシフト荷重は小さくなる。つまり、シフト荷重が所定値よりも大きい場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、シフト荷重が所定値よりも小さい場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
次に、上記クラッチペダル操作判定動作(クラッチペダル70の操作により走行志向を判定する動作)について説明する。このクラッチペダル操作判定動作では、以下の情報(クラッチ操作に応じて変化する操作情報)のうちの少なくとも一つを利用して走行志向が判定される。
(C-2)クラッチストローク位置の変化速度
(C-3)所定クラッチストロークに達するまでの時間
以下、それぞれについて具体的に説明する。
一般にクラッチトルク(Tc)は、エンジントルク(Te)とイナーシャトルク(Iedωe/dt)との和(Tc=Te+Iedωe/dt)として求められる。このイナーシャトルクとは、クラッチ装置6の継合時に、エンジン回転数を引き下げることに伴って伝達されるトルクである。つまり、エンジントルクが同一である場合には、このイナーシャトルクが大きいほどクラッチトルクが大きくなる。例えば、クラッチ装置6の継合時におけるアクセルペダルの踏み込み量が大きい状況で、クラッチペダル70の踏み込み解除速度が高い場合には、単位時間当たりにおけるイナーシャトルクが高くなり、その結果、クラッチトルクも高くなる。このような状況は、運転者がクラッチ装置6の継合を早期に(短時間で)行いたいといった志向がある場合である。従って、このクラッチトルクが所定値よりも高い場合(エンジントルクに対してクラッチトルクが所定値よりも大きい場合)には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、クラッチトルクが所定値よりも低い場合(エンジントルクに対してクラッチトルクが所定値よりも小さい場合)には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
クラッチストローク位置の変化速度は、上記クラッチペダル70の操作移動量(clts)の時間微分値(dclts/dt)により求められる。具体的には、上記クラッチストロークセンサ8Bによって検出されたクラッチストロークの移動量を時間微分することにより求められる。そして、クラッチストローク位置の変化速度が所定値よりも高い場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、クラッチストローク位置の変化速度が所定値よりも低い場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
クラッチペダル70の操作速度が高い場合には、クラッチ装置6の継合に要する時間は短く、逆に、クラッチペダル70の操作速度が低い場合には、クラッチ装置6の継合に要する時間は長くなる。つまり、所定クラッチストロークに達するまでの時間(例えばクラッチ装置6の非継合から継合までの時間)が所定値よりも短い場合には、運転者の走行志向としてはスポーツモード走行志向であると判断できる。逆に、所定クラッチストロークに達するまでの時間が所定値よりも長い場合には、運転者の走行志向としてはコンフォートモード走行志向であると判断できる。これら所定値は実験等により適宜設定される。
(1)次の変速操作が実行されるまで
(2)車両が停車するまで
(3)イグニッションOFF操作がされるまで
つまり、これら何れかの操作が行われるまで、運転者の走行志向の判定結果情報を上記RAM93に記憶させておき、必要に応じて(運転者の走行志向の判定動作が開始されるのに応じて)、この走行志向の判定結果情報をRAM93から読み出すことになる。
次に、上述した走行志向判定動作(シフトレバー操作判定動作やクラッチペダル操作判定動作)によって判定された運転者の走行志向を反映する車両の制御を行う走行志向反映動作について説明する。
(A-2)チップイン、チップアウト特性調整動作
(A-3)フューエルカットオン、フューエルカットオフ特性調整動作
(A-4)VDIM介入タイミング調整動作
(A-5)エアサスペンション特性調整動作
以下、それぞれについて具体的に説明する。
スロットル開度特性調整動作は、運転者の走行志向を反映して、アクセルペダルの踏み込み量に対するスロットルバルブ33の開度特性を調整する動作である。
チップイン、チップアウト特性調整動作は、運転者の走行志向を反映して、チップイン時(アクセルペダルの踏み込み量が急速に大きくなった場合)のスロットルバルブ33の開度特性や、チップアウト時(アクセルペダルの踏み込み量が急速に小さくなった場合)のスロットルバルブ33の開度特性を調整する動作である。
フューエルカットオン、フューエルカットオフ特性調整動作は、アクセルペダル全閉時の被駆動時に実行されるフューエルカット動作時に、運転者の走行志向を反映して、フューエルカットオン時(インジェクタ35からの燃料噴射を停止する際)のエンジントルク特性や、フューエルカットオフ時(インジェクタ35からの燃料噴射を再開する際)のエンジントルク特性を調整する動作である。
VDIM介入タイミング調整動作は、運転者の走行志向を反映して、上述したVDIM制御の介入タイミングを調整する動作である。
エアサスペンション特性調整動作は、運転者の走行志向を反映して、上述したエアサスペンションシステム100における減衰特性を調整する動作である。
次に、上述した走行志向反映制御を実際に実行する場合の制御手順について説明する。ここでは、シフトレバー操作判定動作によって運転者の走行志向を判定して車両走行状態を制御する場合を第1実施形態として、また、クラッチペダル操作判定動作によって運転者の走行志向を判定して車両走行状態を制御する場合を第2実施形態としてそれぞれ説明する。
第1実施形態は、上記シフトレバー操作判定動作としてインプットシャフトISの回転数の単位時間当たりの変化量(dNi/dt)に基づく判定動作を採用し、走行志向反映動作としてスロットル開度特性調整動作及びVDIM介入タイミング調整動作を採用した場合について説明する。
第2実施形態は、上記クラッチペダル操作判定動作としてクラッチトルク及びクラッチ操作速度(クラッチストローク位置の変化速度)に基づく判定動作を採用し、走行志向反映動作としてスロットル開度特性調整動作及びVDIM介入タイミング調整動作を採用した場合について説明する。
以上説明した実施形態では、シフトレバー操作判定動作やクラッチペダル操作判定動作によって運転者の走行志向を判定する場合について説明したが、このようなシフトレバー操作判定動作やクラッチペダル操作判定動作は、運転者の運転の熟練度を判定する指標としても利用可能である。つまり、シフトレバー操作判定動作やクラッチペダル操作判定動作によって運転者の運転の熟練度を判定し、その判定結果に応じて上述した走行志向反映動作と同様の制御動作(運転熟練度反映動作)を行うようにすることも可能である。
