- the engine speed Nr is calculated by the controller 13 from the sensor input cycle from the crank angle sensor 12, but instead includes a rotary encoder, a pulse generator that can detect the teeth of the ring gear, and the like.
- the engine speed Nr may be detected by using another means such as FV (frequency-voltage) conversion of the above signal.
- the pinion gear rotation speed Nst is also detected by a pinion gear rotation speed sensor such as a Hall element, but in addition to the pinion gear rotation speed sensor, a rotation speed table corresponding to the voltage or current applied to the starter motor 17 is also provided.
- the pinion gear rotation speed Nst may be detected using other means.
- FIG. 1 shows the controller 13 and the engine ECU 10 as separate units, the engine ECU 10 may perform processing instead of including the controller 13. Therefore, the engine starter 20 can include the engine ECU 10.

It is determined whether or not the rotational speed Nr 3 is higher than Nr 4 (for example, 250 rpm). If the engine rotational speed Nr is equal to or lower than Nr 2 and equal to or higher than Nr 3 , the process proceeds to step S123 to the starter motor 17. Rotation of the pinion gear 14 is started.

The plunger 15 is moved by this, the pinion gear 14 is moved, and the pinion gear and the ring gear are engaged.
- step S126 the engine is restarted by cranking.
- step S124 if the rotational speed difference between the engine rotational speed Nr and the pinion gear rotational speed Nst is equal to or greater than Ndiff, step S124 is repeated until it becomes smaller than Ndiff.

Abstract
Description
(a)スタータによりクランキングを行わず燃料供給の再開のみでエンジンを再始動させる制御モード。
(b)スタータモータを回転させてピニオンギア回転数とエンジン回転数を同期させて噛み合わせてクランキングによりエンジンを再始動させる制御モード。
(c)スタータモータを回転させずにピニオンギアを移動させ、噛み合わせてからクランキングによりエンジンを再始動させる制御モード。
実施の形態1.
図1はこの発明の実施の形態1によるエンジン始動装置の概略構成を示すブロック図である。図1において、エンジンECU10はアイドルストップ条件(例えば車速5km/h以下かつドライバがブレーキを踏んでいる等)が成り立つか否かを判定し、これをエンジン始動装置20のコントローラ13へと入力する。エンジン始動装置20は、エンジンの(図示しない)クランク軸に連結しているリングギア11と、エンジンのクランク角を検出するクランク角センサ12と、スタータ19と、スタータモータ17とソレノイド16への通電を制御するコントローラ13とを備える。スタータ19は、スタータモータ17の回転を伝えるピニオンギア14と、ピニオンギア14を移動させ、リングギア11と噛み合わせるためのプランジャ15と、通電することによりプランジャ15を可動させることができるソレノイド16と、ピニオンギア14の回転数を検出することのできるピニオンギア回転数センサ18を備える。コントローラ13による通電の制御は、スタータモータ17への通電と、ソレノイド16への通電を独立して制御することができる。
また、スタータ制御手段は、上記コントローラ13およびエンジンECU10の双方、もしくはどちらか一方から構成される。
まずエンジンECU10において、アイドルストップ条件が成立しているか否かを判定する(S110)。成立していなければ次の制御周期へと進む。ステップS110でアイドルストップ条件が成立していたならば、アイドルストップ制御を開始し(S111)、エンジンECU10の制御によりエンジンへの燃料供給をストップさせる。そして、エンジンの惰性回転によりエンジン回転数が降下する間に、エンジンECU10への信号でエンジン再始動条件(例えばドライバがブレーキペダルから足を離す等)が成立しているか否かを判定する(S112)。再始動条件が成立している場合には、ステップS113に進み、再始動条件が成立していない場合には、次の制御周期へと進む。ステップS113では、エンジンが回転中か否かを判定し、エンジンが回転中であると判定された場合には、ステップS114へと進み、エンジン再始動制御を開始する。また、エンジンが回転していない、つまり完全に停止していると判断されたならば、次の制御周期へと進む。ここでエンジンが回転中か否かの判定は、例えば一定期間の間、クランク角センサ12へ入力が来なければエンジンが完全に停止していると判定すればよい。
まずステップS120においてエンジン回転数Nrがエンジン自己復帰可能回転数Nr1(例えば700rpm)以上か否かの判定を行う。
まず、ステップS122で用いるNr2をエンジン自己復帰回転数Nr1より低くし、不感帯を設けた理由について説明する。ここでは、不感帯はエンジン回転数Nr1~Nr2の領域に設定されている。
前述のようにピストンの運動による膨張・圧縮トルクにより、脈動を発生させながらエンジン回転数Nrは低下していき、前記Nr3より小さく、前記Nr4より大きい場合に再始動要求があった場合に直ぐにピニオンギア14を移動させ噛み合わせようとした場合に、前記トルク変動によりエンジン回転数Nrが上昇し、噛み合い可能な回転数Nr4になるまで時間を要し、ギア磨耗や騒音を発生させる可能性がある。
また、この実施の形態では、エンジン回転数により制御モードの決定を行っていたが、クランク角やアイドルストップを開始してからの時間等、エンジンの運動状態に関連する値を代わりに用いても同様の効果が得られる。
図8はこの発明の実施の形態2によるエンジン始動装置の概略構成を示すブロック図である。図8のエンジン始動装置では、エンジンに吸入される吸気量を検出するエアフローセンサ(吸気量検出手段)23を備え、この吸気量に基づき、実施の形態1において、不感帯を決定していたエンジン回転数Nr1、Nr2、Nr3、Nr4を設定してもよい。図8では、コントローラはコントローラ24と表記している。
また、上記実施の形態2において吸気量検出手段はエアフローセンサ23である必要はなく、スロットルバルブ開度を用いても同様の効果が得られる。
