- Stoppers 51A and 51B for restricting the operating range of the detent lever 5A are disposed on both sides in the rotational direction of the detent lever 5A.
- the rotational movement of the range switching shaft 4 is converted into the axial movement of the range switching valve 6 by the engagement of the detent lever 5A and the range switching valve 6, and the range switching valve 6 is displaced in the axial direction within the valve body 7. By doing so, the opening and closing of the hydraulic port is switched, and the line pressure is delivered according to each shift range.

- step S11 it is determined whether a learning condition is satisfied.
- the learning condition is set so that learning is performed in a vehicle stationary state that does not affect vehicle travel. For example, it is preferable that the vehicle is stopped and that the parking brake is used. Further, learning may be performed (included as a learning condition) before the product is shipped from the factory.
- step 12 the detent lever 5A is driven from the current position (P range position) toward the one stopper 51A and is brought into contact with the stopper 51A (see the dotted line in FIG. 4A).
- the stopper 51A Even in a state where the detent lever 5A is in contact with the stopper 51A, the stopper so that the pawl 10a of the parking pole 10 is engaged with the recess 11a of the parking gear 11 and the fixing (parking lock) of the parking gear 11 is maintained.

- the predetermined angle ⁇ 2 is set so as to be within an effective range in which the pull-in operation occurs when the predetermined angle ⁇ 2 is driven and stopped. Even when the detent lever 5A is driven at a predetermined angle ⁇ 2 away from the stopper 51A, the pawl 10a of the parking pole 10 is engaged with the recess 11a of the parking gear 11, and the parking gear 11 is fixed (parking locked). It is desirable to set the predetermined angle ⁇ 2 as described above and acquire a second learning value described later in a more stable vehicle stationary state.
- step 18 as described above, the roller 5b moves from the side close to the stopper 51A toward the valley of the recess 5a and naturally stops, and the angle of the range switching shaft 4 detected by the potentiometer 21 is changed to the P range. It is stored as a second learning value for the target angle.

- a predetermined play amount is provided in the power transmission path between the motor 2 and the range switching shaft positioned at an angle corresponding to each range by the detent mechanism.
- the potentiometer 21 is often attached to the output shaft on the motor 2 side. In that case, the detected angle when the range switching shaft 4 is rotated in one direction is detected as a value that is larger by the amount of play than when there is no play, and the detected angle when rotated in the reverse direction is greater than that when there is no play. It will be detected as a smaller value.
- the first learning value obtained by the pull-in operation from the stopper 51A side is detected as a value smaller by the play amount, and obtained by the pull-in operation from the opposite side to the stopper 51A.

- the influence of friction can be offset and the target angle can be set with higher accuracy.
- a method is also known in which the valley position of the recess is obtained by calculating the angular velocity and angular acceleration of the detected angle value, but a high-functional CPU is required to accurately calculate the angular velocity and angular acceleration.
- such a complicated calculation is not required, and a highly accurate shift range position can be set using a relatively low-cost CPU.
- FIG. 6 shows a time chart during control of switching from the P range to another range (notP range) and then switching from the notP range to the P range.
- a three-phase alternating current obtained by converting a direct current from a battery into a three-phase inverter is used as the motor 2, and the PWM duty output to the three-phase inverter is calculated from the peak voltage (absolute value) and controlled.
- the peak voltage manipulated variable VPEAK is a positive value.
- VPEAK is negative. Set to value.
- the P and I minutes in PI control are determined according to the deviation between the current position (actual angle) of the range switching shaft 4 detected by the potentiometer 21 and the notP range position after the range is switched. Are set respectively.
- a feed forward gain (FF gain) is set according to the current position of the range switching shaft 4.
- the FF gain has a characteristic of gradually decreasing from a positive predetermined value corresponding to the P range position to a negative predetermined value corresponding to the notP range position.
- the peak voltage manipulated variable VPEAK is set by converting a value obtained by adding the P, I and FF gains.
- the position corresponding to the shift range (the rotation angle of the range switching shaft 4) is learned and corrected, whereby the corrected range corresponding position (target angle) and the range switching shaft 4 detected by the potentiometer 21 are detected. Based on the current position, the position can be quickly and accurately positioned (the roller is positioned at the valley of the recess) at the range position after switching.
- the learning of the notP range position will be described with reference to the flowchart of FIG. 7 after the learning of the P range position shown in FIG. 3.
- the learning may be performed independently after newly determining whether the learning condition is satisfied.
- step S21 the detent lever 5A is driven from the current P range position toward the stopper 51A and is brought into contact with the stopper 51A.

- step 23 the driving of the range switching shaft 4 is stopped. Thereby, the pulling operation of the detent mechanism 5 by the elastic urging force of the detent spring 5B moves the roller 5b from the position on the wall opposite to the stopper 51A toward the valley of the recess 5a corresponding to the notP range. Stop naturally.

- step 26 the driving of the range switching shaft 4 is stopped.
- the retracting operation of the detent mechanism 5 by the elastic biasing force of the detent spring 5B causes the roller 5b to move toward the valley of the recess 5a from the position where the roller 5b rides on the wall on the stopper 51A side, and stops naturally.
- the predetermined angle ⁇ 12 is set to an effective range in which the pull-in operation occurs when the predetermined angle ⁇ 12 is driven and stopped.

It is stored as a second learning value for the target angle.
- a target angle learned in the P range is determined based on the first learning value and the second learning value. For example, a value obtained by averaging the first learning value and the second learning value is set as the notP range target angle.

In this way, it is not necessary to bring the detent lever 5A into contact with the stopper 51A, and the learning time can be shortened.
- the drive amount to the retracting operation position is smaller when the notP range position is far from the P range position and is brought into contact with the stopper 51B opposite to the stopper 51A. is there.
- the learning value corresponding to the range position or the detected value during learning shows an abnormal value, it is determined that some abnormality may have occurred, the drive of the motor 2 is stopped, and an alarm is issued. Is preferably output.

アクチュエータと、該アクチュエータにより駆動され、変速機レンジに対応する位置に形成された凹部に係合されて位置決めされることにより、変速機のレンジを変更するディテント機構と、該ディテント機構を、その移動範囲の限界位置まで駆動してから該限界位置から離れる方向に所定量駆動し、該ディテント機構が前記凹部の谷に向かって移動し自然停止したときの位置を、変速機レンジに対応する位置として設定する制御部と、を含んで構成される。
アクチュエータによりディテント機構を駆動し、該ディテント機構を変速機レンジに対応する位置に形成された凹部に係合させて位置決めすることにより、変速機のレンジを変更する自動変速機のレンジ切換え方法であって、ディテント機構を、その移動範囲の限界位置まで駆動してから該限界位置から離れる方向に所定量駆動し、該ディテント機構が前記凹部の谷に向かって移動し自然停止したときの位置を、前記変速機レンジに対応する位置として設定する。
図1は、実施の形態における自動変速機のレンジ切換え装置のシステム構成図である。
図1において、車両に搭載される自動変速機1には、後述するレンジ切換バルブ6を駆動するためのモータ2(アクチュエータ)が取り付けられる。
尚、前記減速歯車機構3の最終段とレンジ切換シャフト4とのスプライン係合等による連結部には、回転方向に所定の遊び量が設けられている。
前記ディテント機構5は、図2に示すように構成されている。ディテントレバー5Aは、レンジ切換シャフト4に固定されて一体に回転する。ディテントスプリング5Bは、ディテントレバー5Aの周縁に各レンジに対応して形成される凹部5aに係合するローラ5bを支持すると共に、該ローラ5bを前記凹部5aに向けて押圧付勢する。
前記レンジ切換シャフト4の回転運動は、ディテントレバー5Aとレンジ切換バルブ6との係合によって、レンジ切換バルブ6の軸方向運動に変換され、レンジ切換バルブ6がバルブボディ7内で軸方向に変位することで、油圧ポートの開閉が切り換えられ、各シフトレンジに応じてライン圧を配送する。
前記ポテンショメータ21,インヒビタスイッチ22及びレンジセレクトスイッチ23からの信号は、A/Tコントロールユニット(A/T C/U)24に入力される。
ステップ12では、ディテントレバー5Aを現在の位置(Pレンジ位置)から一方のストッパ51Aに向けて駆動し、ストッパ51Aに当接させる(図4(A)の点線参照)。
ステップ15では、上記のようにローラ5bがストッパ51Aから離れた側から凹部5aの谷に向かって移動して自然停止した状態において、ポテンショメータ21で検出されたレンジ切換シャフト4の角度を、Pレンジに対応する位置(Pレンジ目標角度)の第1学習値として記憶する。

なお、凹部の谷位置を角度検出値の角速度や角加速度を算出して求める方法も知られるが、角速度,角加速度を精度よく演算するため高機能のCPUが必要となる。これに対し、本実施形態では、このような複雑な演算が不要であり比較的低コストなCPUを用いて高精度な変速レンジ位置の設定を行うことができる。
本実施形態では、モータ2として例えばバッテリからの直流電流を3相インバータに変換した3相交流を用い、3相インバータに出力されるPWMデューティをピーク電圧(絶対値)から算出して制御する。また、レンジ切換シャフト4をPレンジからnotPレンジ位置に切り換えるときの回転方向では、ピーク電圧操作量VPEAKを正の値、notPレンジ位置からPレンジ位置に切り換えるときの回転方向では、VPEAKを負の値に設定する。
以下、図3に示したPレンジ位置の学習終了後、notPレンジ位置の学習を行う場合について図7のフローチャートに従って説明するが、例えば、停車毎に学習するレンジを変更する等、notPレンジ位置の学習を新たに学習条件成立の判断を行った後、単独で行うようにしてもよい。
なお、notPレンジ位置の学習を行う場合は、学習成立条件としてパーキングブレーキの使用を含めることが安定した車両静止状態を確保できるので好ましい。
ステップS22では、ディテントレバー5Aをストッパ51Aに当接させた位置から、レンジ切換シャフト4を、ストッパ51Aから離れる方向に所定角度θ11駆動する。これにより、ディテントスプリング5Bのローラ5bがnotPレンジに対応する凹部5aの谷からストッパ51Aと反対側の壁に所定量乗り上げた位置に達する。
ステップ24では、上記のようにローラ5bがストッパ51Aから離れた側から凹部5aの谷に向かって移動して自然停止した状態で、前記自然停止した状態において、ポテンショメータ21で検出されたレンジ切換シャフト4の角度を、notPレンジに対応する位置(notPレンジ目標角度)の第1学習値として記憶する。
ステップ27では、上記のように、ローラ5bがストッパ51Aに近い側から凹部5aの谷に向かって移動して自然停止した状態で、ポテンショメータ21で検出されたレンジ切換シャフト4の角度を、Pレンジ目標角度の第2学習値として記憶する。
