- the horizontal axis indicates time.
- the vertical axis in FIG. 7 indicates, from the top, the brake operation of the driver, the engine stop condition calculated in the engine control unit 80, the engine braking mode calculated in the engine stop unit 70, the engine speed, and the engine rotation. Number, target braking torque, actual braking torque, and engine crank angle.
- the solid line indicates the operation when the engine stop position is controlled by the processing according to the first embodiment of the present invention

Furthermore, since the power generation braking torque cannot be applied after time T3, the behavior until the engine is stopped is determined by the inertia of the engine, and does not necessarily stop near the calculated target stop position.
- the field current does not flow until immediately before, so the field current increases with a predetermined time constant. Therefore, a certain amount of predetermined time is required until the target braking torque can be realized. During this time, the engine speed changes gradually with respect to the target engine speed. As a result, the time until the target stop position is reached is delayed.
- the engine reaches the target stop position.

- the engine speed in the prior art in which the engine stop position is controlled only in the dynamic braking mode reaches zero. Since the braking torque is not applied (not controlled) from time T3 to time T5, the stop position at the time of zero rotation is greatly deviated from the target stop position. In addition, since the braking torque is not applied immediately before the engine stops rotating, the engine reversely rotates (shakes back).

- the engine stop angle is closer to the target stop position than the engine crank angle at time T5
- the braking torque is not controlled near the target stop position, so the engine stops near the target stop position. You can see that they are not.
- FIGS. 8 and 9 show the high rotation short circuit braking mode (near time T3 in the short circuit braking mode shown in FIG. 7), and FIG. 9 shows the low rotation short circuit braking mode (near time T4 in the short circuit braking mode shown in FIG. 7). ).
- the horizontal axis indicates time. 8 and 9 indicate the engine speed, rotational acceleration, field current, semiconductor switch, and braking torque in order from the top. 8 and 9, the target rotational speed, the target torque, and the actual braking torque are actually represented by diagonal lines, but are represented by straight lines for simplicity.

- the average rotation speed is calculated near the center of the amplitude.
- Rotational acceleration is obtained by differential calculation of instantaneous rotational speed.
- the field current is controlled to be a constant value based on an average target torque (described later) and a short-circuit braking torque characteristic.
- the semiconductor switch is turned on when the rotational acceleration is positive (three-phase short-circuit execution), and turned off when the rotational acceleration is negative (circuit open, no three-phase short-circuited). Also, the braking torque is not generated when the semiconductor switch is off (circuit open, no three-phase short circuit), and when the semiconductor switch is on (three-phase short circuit execution), a predetermined magnitude of braking torque is generated. .
- the average target torque is obtained based on the difference between the average rotational speed and the target rotational speed.
- the instantaneous rotational speed pulsates with a predetermined width because the vertical movement of a plurality of pistons is changed to rotational movement.
- the average rotation speed is calculated near the center of the amplitude.

- the semiconductor switch is always on (three-phase short-circuit execution).
- the braking torque is controlled with a value corresponding to the rotational acceleration. That is, if the rotational acceleration is positive, the braking torque is large, and if the rotational acceleration is negative, the braking torque is small.
- the average target torque is obtained based on the difference between the average rotational speed and the target rotational speed.
- the target torque is calculated as a value obtained by adding a value obtained by arbitrarily multiplying the rotational acceleration to the average target torque.
- the engine stop unit when the engine stop condition is satisfied, the engine stop unit first selects the power generation braking mode for applying the power generation braking torque to the engine by the power generation operation of the generator. Then, by applying a power generation braking torque to the engine, and then short-circuiting each energized phase of the armature winding by a semiconductor switch, a short-circuit braking torque is applied to the engine by flowing a field current through the field winding. Select the short-circuit braking mode to apply and apply short-circuit braking torque to the engine. Therefore, it is possible to obtain an engine stop control device and an engine stop control method with high energy efficiency and low power consumption while accurately stopping the engine at the target stop position without causing swing back. That is, the period of the short-circuit braking mode can be shortened as much as possible to reduce power consumption, and kinetic energy can be recovered as electrical energy as much as possible.
- the controllability of the stop position control can be improved in a wide rotation range by switching the braking modes having different torque characteristics.
- the engine stop unit switches from the power generation braking mode to the short-circuit braking mode when the rotational speed of the engine becomes less than the predetermined rotational speed.
- the braking mode can be switched at an appropriate timing without adding a special device.
- the predetermined number of revolutions is calculated based on the time constant of the field winding.
- the predetermined rotational speed is a rotational speed at which the generated voltage of the generator falls below the battery voltage of the battery connected to the generator when a rated current is passed through the field winding. Therefore, since the power generation braking mode is maintained up to the power generation limit rotational speed, kinetic energy can be regenerated and stored as electric power, and high energy efficiency can be realized.
- the engine stop unit switches from the power generation braking mode to the short-circuit braking mode when the current flowing from the generator to the battery falls within a predetermined range near zero A.
- the power generation braking mode can be maintained until the last minute, so that kinetic energy can be regenerated and stored as electric power, and high energy efficiency can be realized.
- the engine stop unit controls the field current so that the short-circuit braking torque increases as time elapses after switching to the short-circuit braking mode. Therefore, by controlling the field current so that the torque in the low rotation range increases, it is possible to prevent the swinging back.
- the engine stop unit controls the short-circuit braking mode by controlling the field current to a constant current value and switching the short-circuit braking on and off by the semiconductor switch, and the short-circuit braking by the semiconductor switch.
- the short-circuit braking mode switching speed calculated based on the time constant of the field winding is divided into the low-rotation short-circuit braking mode in which the field current is controlled to a current value that generates torque that cancels engine rotational fluctuations.
- the high-rotation short-circuit braking mode and the low-rotation short-circuit braking mode are switched according to.
- the engine can be accurately stopped at the target stop position, and variation between cylinders can be reduced regardless of the rotational speed. , Drivability can be improved. Further, by calculating the short-circuit braking mode switching speed based on the time constant of the field winding, it is possible to enhance the effect of suppressing fluctuations in the engine speed.
- the generator is a generator motor. Therefore, even if the vehicle is equipped with a generator motor as a restarting starter, the present invention can be applied, and drivability can be improved without significant hardware changes.

Abstract
Description
特許文献1に係る発明において、再始動性を向上させるためには、上述したクランク角範囲をより精度良く制御する必要があるが、極低回転域で発電制動トルクを確保することができないので、エンジンの逆回転(揺り戻し)が発生し、逆回転中に再始動要求があった場合には、正転中よりも大きな駆動力が必要になるので、結果的に始動性が低下するという問題がある。
また、この発明に係るエンジン停止制御方法によれば、エンジン停止条件が成立した場合に、発電機の発電動作によって、エンジンに対して発電制動トルクをかける発電制動モードを選択するステップと、このステップに続いて、半導体スイッチによって電機子巻線の各通電相を短絡するとともに、界磁巻線に界磁電流を流すことにより、エンジンに対して短絡制動トルクをかける短絡制動モードを選択するステップとを有している。
そのため、揺り戻しを発生させることなく、目標停止位置に精度良くエンジンを停止させるとともに、消費電力が少なく、エネルギ効率の高いエンジン停止制御装置およびエンジン停止制御方法を得ることができる。
図1は、この発明の実施の形態1に係るエンジン停止制御装置を示す構成図である。図1において、このエンジン停止制御装置は、界磁巻線型の発電機10(以下、単に「発電機10」と称する)、電機子巻線駆動回路20、発電機電力センサ30、バッテリ電圧センサ40、バッテリ50、発電機駆動部60、エンジン停止部70およびエンジン制御部80を備えている。
ステップS101において、エンジン停止条件が成立していない(すなわち、No)と判定された場合には、そのまま図5の制御処理が終了する。
次に、エンジン停止処理のサブルーチンが実行され(ステップS104)、図5の制御処理が終了する。
ステップS201において、制動モード切り替え条件が成立していない(すなわち、No)と判定された場合には、制動モードが発電制動モードに設定される(ステップS202)。
続いて、界磁巻線駆動指令値生成部61において、ステップS203で算出された目標制動トルクを実現するために必要な目標界磁電流が、上述した発電制動トルク特性から算出される(ステップS204)。
続いて、半導体スイッチ制御部62により、発電動作となるように、半導体スイッチを用いて通電相が切り替えられて(ステップS206)、ステップS222に移行する。このとき、電機子巻線駆動回路20により、半導体スイッチ制御部62からの指令に基づいて、半導体スイッチが切り替えられる。
続いて、界磁巻線駆動指令値生成部61において、ステップS208で算出された目標制動トルクを実現するために必要な目標界磁電流が、上述した短絡制動トルク特性から算出される(ステップS210)。
次に、ステップS212で算出されたエンジン回転加速度の正負が判定される(ステップS213)。
次に、目標回転数と現在のエンジンの平均回転数との差が任意の所定倍されて、目標制動トルクが算出される(ステップS218)。
次に、界磁巻線駆動指令値生成部61により、ステップS219で算出された目標界磁電流が、界磁巻線駆動回路13に指令される(ステップS220)。
一方、ステップS222において、エンジンが停止していない(回転中である)(すなわち、No)と判定された場合には、ステップS201に戻って、処理が繰り返し実行される。
続いて、時刻T1において、ドライバはブレーキを踏み、車両は減速を開始する。
そのため、揺り戻しを発生させることなく、目標停止位置に精度良くエンジンを停止させるとともに、消費電力が少なく、エネルギ効率の高いエンジン停止制御装置およびエンジン停止制御方法を得ることができる。
すなわち、短絡制動モードの期間を極力短くして、消費電力を抑えるとともに、可能な限り、運動エネルギを電気エネルギとして回収することができる。
また、異なるトルク特性の制動モードを切り替えることにより、広い回転域において、停止位置制御の制御性を向上させることができる。
ここで、エンジンの回転センサは、一般的な車両には搭載されているので、特別な装置を追加することなく、適切なタイミングで制動モードを切り替えることができる。
そのため、エンジンの気筒間周期が界磁巻線の時定数よりも長い領域において、短絡制動による停止位置制御が効果的に働かないことにより、不必要に電力を消費したり、精度良く制御できなくなったりすることを防止することができる。
そのため、発電限界回転数まで発電制動モードを維持するので、運動エネルギを回生して、電力として蓄えることができ、高いエネルギ効率を実現することができる。
ここで、充電電流を直接検出することにより、ぎりぎりまで発電制動モードを維持することができるので、運動エネルギを回生して、電力として蓄えることができ、高いエネルギ効率を実現することができる。
そのため、界磁電流を、低回転域でのトルクが増大するように制御することにより、揺り戻しを防止することができる。
そのため、低回転域において、制動トルクの制御性が高い界磁電流による短絡制動を導入することにより、目標停止位置に精度良くエンジンを停止させるとともに、回転数によらず気筒間変動を小さくして、ドライバビリティを向上させることができる。
また、短絡制動モード切り替え回転数を、界磁巻線の時定数に基づいて算出することにより、エンジン回転数の変動抑制効果を高めることができる。
そのため、再始動用の始動装置として、発電電動機を備えた車両であっても、本発明を適用することが可能となり、ハードウェアの大きな変更なしに、ドライバビリティを向上させることができる。
