- the MG1 rotation angle position changes to the side where the cogging torque increases as indicated by the arrow Y1.
- the MG1 rotation angle position changes to the side where the cogging torque decreases as indicated by the arrow Y2. That is, the change in the MG1 rotation angle position indicates a change in the cogging torque of the first rotating machine MG1, and indicates a change in the input torque to the rotor 4.
- the ECU 50 detects the clutch engagement position based on the change in the cogging torque due to the change in the input torque to the rotor 4.
- the ECU 50 can learn the clutch stroke at which the MG1 rotation angle position starts to change when the clutch stroke is increased from the state in which the clutch CL1 is released as the engagement position of the clutch CL1. Further, the ECU 50 does not learn a clutch stroke in which the MG1 rotation angle position does not change as the clutch stroke is increased, as a joint position.
- the ECU 50 determines the clutch stroke in which the MG1 rotation angle position does not change when the clutch CL1 is engaged and the clutch stroke is decreased from the state in which the first rotating machine MG1 has stopped rotating due to the cogging torque. It can be learned as a joint position. In addition, the ECU 50 does not learn the clutch stroke in which the MG1 rotation angle position changes when the clutch stroke is decreased as the joining position.

- step S101 the ECU 50 determines whether or not the vehicle is traveling in the disconnected state. For example, the ECU 50 makes an affirmative determination in step S101 when the vehicle travels with the clutch CL1 disengaged. In step S101, it is determined whether the joint position learning control of the clutch CL1 can be started. When executing the learning control of the joining position, the first rotating machine MG1 may be shut down and stopped by the cogging torque. For example, the ECU 50 makes an affirmative determination in step S101 during EV traveling, and learns the engagement position of the clutch CL1. As a result of the determination in step S101, if it is determined that the vehicle is traveling in the disconnected state (step S101-Y), the process proceeds to step S102, and if not (step S101-N), the control flow ends.

- the ECU 50 determines whether or not the MG1 rotation angle position detected by the rotation angle position detection device 5 has changed before and after the clutch stroke command value is changed in step S103.
- step S104-Y if it is determined that the MG1 resolver angle has changed (step S104-Y), the process proceeds to step S105. If not (step S104-N), the process proceeds to step S103, where the clutch stroke Is increased.
- step S105 the ECU 50 sets the current stroke to the learning point 1.

- step S106 the ECU 50 moves the clutch stroke from the current stroke by a stroke change amount ⁇ strk.
- the ECU 50 increases the clutch stroke command value by the stroke change amount ⁇ strk to further move the coupling element of the clutch CL1 in the coupling direction.
- step S107 the ECU 50 determines whether or not a predetermined stroke has been reached.
- the predetermined stroke is a clutch stroke larger than the clutch stroke at the joining position, and is determined in advance. As shown in FIG. 5, the predetermined stroke st5 is larger than the learning point 1 (clutch stroke st4).
- the ECU 50 moves the coupling element of the clutch CL1 in the release direction to learn the coupling position.
- step S107 if it is determined that the predetermined stroke has been reached (step S107-Y), the process proceeds to step S108. If not (step S107-N), the process proceeds to step S106, and the clutch stroke is Will be increased.

- the ECU 50 decreases the clutch stroke command value by the stroke change amount ⁇ strk and moves the coupling element of the clutch CL1 in the release direction.
- step S109 the ECU 50 determines whether or not the MG1 resolver angle has changed.
- the ECU 50 determines whether or not the MG1 rotation angle position detected by the rotation angle position detection device 5 has not changed before and after the clutch stroke command value is changed in step S108.
- step S109-Y if it is determined that the MG1 resolver angle has not changed (step S109-Y), the process proceeds to step S110. If not (step S109-N), the process proceeds to step S108, and the clutch stroke Is reduced.
- step S110 the ECU 50 sets the current stroke to the learning point 2.
- the change in the MG1 resolver angle is not detected at time t2, and the current stroke st2 at this time is set to the learning point 2.
- step S111 the ECU 50 learns the clutch stroke calculated by the following equation (1) as the engagement start point.
- (Learning point 1 ⁇ strk) in the above equation (1) is a clutch stroke at which the MG1 rotation angle position starts to change, and in the case of FIG. 5, is the clutch stroke st3.

- the ECU 50 determines the clutch stroke (learning point 1- ⁇ strk) at which the MG1 rotation angle position starts to change while the clutch stroke is increasing, and the clutch stroke (learning point 2 + ⁇ strk) at which the MG1 rotation angle position does not change while the clutch stroke is decreasing. ) Is learned as the engagement position of the clutch CL1. Variation in learning can be reduced by using the average stroke as the joining position.

Further, the ECU 50 may learn the clutch stroke (the learning point 2 + ⁇ strk) at which the MG1 rotation angle position does not change as the joining position.
- the clutch stroke at which the MG1 rotation angle position starts to change may be the learning point 1 or another clutch stroke.

It may be a clutch stroke immediately after the position is changed.
- the clutch stroke at which the MG1 rotation angle position does not change may be the learning point 2 or another clutch stroke. That is, the clutch stroke at which the MG1 rotation angle position does not change is the MG1 rotation even if the clutch stroke immediately before the MG1 rotation angle position does not change when the clutch stroke command value is decreased by the stroke change amount ⁇ strk. It may be a clutch stroke immediately after the angular position no longer changes.

Abstract
Description
図1から図5を参照して、実施形態について説明する。本実施形態は、車両制御装置に関する。図1は、本発明の実施形態に係る車両のスケルトン図、図2は、実施形態のEV走行モードに係る共線図、図3は、コギングトルクの一例を示す図、図4は、実施形態の学習制御に係るフローチャート、図5は、実施形態の学習制御に係るタイムチャートである。
{(学習点1-Δstrk)+(学習点2+Δstrk)}/2…(1)
上記式(1)の(学習点1-Δstrk)は、MG1回転角度位置が変化し始めるクラッチストロークであり、図5の場合、クラッチストロークst3である。上記式(1)の(学習点2+Δstrk)は、MG1回転角度位置が変化しなくなるクラッチストロークであり、図5の場合、クラッチストロークst3である。
MG1回転角度位置が変化し始めるクラッチストロークは、学習点1とされてもよいし、その他のクラッチストロークとされてもよい。つまり、MG1回転角度位置が変化し始めるクラッチストロークは、クラッチストローク指令値をストローク変化量Δstrkずつ増加させていくときの、MG1回転角度位置が変化する直前のクラッチストロークであっても、MG1回転角度位置が変化した直後のクラッチストロークであってもよい。
上記実施形態では、車両100の走行中にクラッチCL1の継合位置の学習制御が実行されたが、クラッチCL1に差回転が生じている他の状況下で学習制御を実行することも可能である。例えば、車両100が停車し、エンジン1が運転している状況でクラッチCL1の継合位置を学習することができる。この場合、ECU50は、車両100の停車中に、エンジン1が運転し、第一回転機MG1が停止し、かつクラッチCL1が開放した状態からクラッチストロークを増加させていくときに継合位置を学習することができる。上記実施形態と同様に、MG1回転角度位置が変化し始めるクラッチストロークをクラッチCL1の継合位置として学習するようにすればよい。
上記実施形態では、ECU50は、始めにクラッチCL1を継合させていきながら継合位置を検出し、次にクラッチCL1を開放させていきながら継合位置を検出したが、これとは逆の順序で継合位置の学習がなされてもよい。
上記実施形態では、ストローク変化量ΔstrkがクラッチCL1の最小移動量であったが、これには限定されない。ストローク変化量Δstrkは、最小移動量よりも大きなクラッチストロークであってもよい。ストローク変化量Δstrkは、最小移動量の数ステップ分であってもよい。ストローク変化量Δstrkは、ストローク変化量Δstrkだけクラッチストロークを変化させる時のクラッチトルク容量の変化により、第一回転機MG1の入力トルクの大きさが最大コギングトルク(正の極値Tc1や負の極値Tc2の大きさ)以上とならないように定められていればよい。
適用対象の車両100は、実施形態で例示したものには限定されない。例えば、エンジンと、回転機と、回転機および駆動輪とエンジンとを断接するクラッチを搭載した車両に対しても上記実施形態の車両制御装置1-1は適用可能である。こうした車両では、停車中に、クラッチを開放し、回転機を停止し、かつエンジンを運転した状態から、クラッチの継合位置の学習制御を行うことができる。また、停車中に、エンジンを運転し、回転機がコギングトルクで停止するようにクラッチを継合した状態から、クラッチの継合位置の学習制御を行うことができる。例えば、上記第2変形例と同様にしてクラッチの継合位置を学習することができる。
上記実施形態では、回転角度位置検出装置5の検出結果に基づいてコギングトルクの変化が検出されたが、他の方法でコギングトルクの変化が検出されてもよい。また、回転角度位置検出装置5は、レゾルバには限定されない。回転角度位置検出装置5は、少なくともコギングトルクの変化によるMG1回転角度位置の変化を検出できるものであればよい。
上記実施形態では、第一回転機MG1が第一サンギア11に接続され、クラッチCL1が第一キャリア14に接続されていたが、これには限定されない。例えば、第一回転機MG1およびクラッチCL1は、それぞれ第一遊星歯車機構10における上記実施形態とは異なる回転要素に接続されていてもよい。また、第一回転機MG1とクラッチCL1とが第一遊星歯車機構10のような差動機構を介さずに接続されていてもよい。つまり、クラッチCL1は、継合することで第一回転機MG1に対してトルクを伝達できるように配置されているものであればよい。
