Description
まず、図1に基づいてレンジ切換機構11の構成を説明する。
レンジ切換機構11の駆動源となるモータ12は、例えばスイッチトリラクタンスモータにより構成され、減速機構26(図4参照)を内蔵し、その出力軸13の回転位置を検出する出力軸センサ14が設けられている。この出力軸13には、ディテントレバー15が固定されている。
本実施例1では、モータ12として、スイッチトリラクタンスモータ(以下「SRモータ」と表記する)が用いられている。このSRモータ12は、ステータ31とロータ32が共に突極構造を持つモータで、永久磁石が不要で構造が簡単であるという利点がある。円筒状のステータ31の内周部には、例えば12個の突極31aが等間隔に形成され、これに対して、ロータ32の外周部には、例えば8個の突極32aが等間隔に形成され、ロータ32の回転に伴い、ロータ32の各突極32aがステータ31の各突極31aと微小ギャップを介して順番に対向するようになっている。
尚、Z相信号用の磁気検出素子50の出力は、ロータ32の基準回転位置に相当する幅広なN’極に対向する毎にハイレベル“Hi”となり、それ以外の位置では、ローレベル“Low”となる。
図12に示すように、PレンジでECU41に電源が投入されたときに初期駆動を行う場合は、例えば、W相通電→UW相通電→U相通電→UV相通電→V相通電→VW相通電の順序で通電相の切り換えを所定のタイムスケジュールで一巡し、ロータ32を正回転方向(Pレンジ→NotPレンジの回転方向)に駆動する。
CASE=1(2回目の励磁)の場合は、ステップ208に進み、UW相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
CASE=3(4回目の励磁)の場合は、ステップ210に進み、UV相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
CASE=5(6回目の励磁)の場合は、ステップ212に進み、VW相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
CASE=1(2回目の励磁)の場合は、ステップ228に進み、UV相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
CASE=3(4回目の励磁)の場合は、ステップ230に進み、UW相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
CASE=5(6回目の励磁)の場合は、ステップ232に進み、VW相通電を選択し、その通電時間TをT2(例えば100ms)にセットする。
(2) 励磁回数カウンタCASEが2又は4、つまり2相通電終了時であること
(3) レンジ切換操作フラグXchgがON、つまり初期駆動中にレンジ切換操作が行われたこと
これら3つの条件(1) 〜(3) のうち、1つでも満たさない条件があれば、初期駆動の途中終了条件が成立せず、初期駆動を継続する。
Ncnt=Ncnt+288
Gcnt=Ncnt+2×(6−CASE)
図15の初期駆動ルーチンは、前記実施例1で説明した図8及び図9の初期駆動ルーチンのステップ116とステップ117の処理をそれぞれステップ116aとステップ117aの処理に変更し、且つ、ステップ124の前にステップ118aを追加したものであり、それ以外の処理は前記実施例1と同じである。
(2) 励磁回数カウンタCASEが2又は4又は8、つまり2相通電終了時であること
(3) レンジ切換操作フラグXchgがON、つまり初期駆動中にレンジ切換操作が行われたこと
これら3つの条件(1) 〜(3) のうち、1つでも満たさない条件があれば、初期駆動の途中終了条件が成立せず、初期駆動を継続する。
