Description

この発明は、エンジンのクランク軸に連結された発電電動機と、エンジン始動時にピニオンをリングギヤに噛合させるスタータとを備え、発電電動機およびスタータの少なくとも一方を起動してエンジンをクランキングするエンジン始動装置に関する。   The present invention relates to an engine starter that includes a generator motor connected to a crankshaft of an engine and a starter that meshes a pinion with a ring gear when the engine is started, and cranks the engine by starting at least one of the generator motor and the starter. .

従来から、エンジンの停止条件が成立するとエンジンを自動停止させ、その後再始動条件が成立するとエンジンを再始動させるエンジン自動停止再始動制御を行う車両において、エンジン始動時にエンジンのクランキングを行う発電電動機およびスタータが搭載されているものが知られている。   Conventionally, a generator motor that performs engine cranking when starting an engine in a vehicle that performs engine automatic stop / restart control that automatically stops the engine when the engine stop condition is satisfied and then restarts the engine when the restart condition is satisfied And what is equipped with a starter is known.

このような車両では、エンジン始動時のクランキングにおいて、発電電動機とスタータとを状況に応じて使い分けるか、または発電電動機とスタータとを併用して、エンジンを始動するようになっている。   In such a vehicle, in cranking when starting the engine, the generator motor and the starter are selectively used according to the situation, or the generator motor and the starter are used together to start the engine.

ここで、エンジンの水温等に関する情報に基づいて、歯車伝動装置を介してエンジンを始動するスタータである第一の始動装置と、ベルト伝動装置を介してエンジンを始動する発電電動機である第二の始動装置とを、それぞれ単独で使用するか、または併用するかを選択してエンジンをクランキングするエンジンの始動制御装置が知られている（例えば、特許文献１参照）。   Here, based on information on the engine water temperature and the like, a first starter that is a starter that starts the engine via a gear transmission and a second generator that is a generator motor that starts the engine via a belt transmission 2. Description of the Related Art An engine start control device is known that cranks an engine by selecting whether the start device is used alone or in combination (see, for example, Patent Document 1).

なお、特許文献１に記載のエンジン始動制御装置では、第一の始動装置と第二の始動装置とを併用してエンジンをクランキングする場合に、第一の始動装置を駆動させるとともに、その後第二の始動装置を駆動させ、ついで第一の始動装置を停止した後も第二の始動装置の駆動を継続させている。   In the engine start control device described in Patent Document 1, when the engine is cranked using both the first start device and the second start device, the first start device is driven, and then the first start device is driven. The second starter is driven and then the second starter is continuously driven even after the first starter is stopped.

また、キーの操作によるエンジンの始動時にスタータであるスタータモータで起動するとともに、発電電動機である電動発電機によって常時アシストする車両において、エンジンの再始動時に、スタータモータと電動発電機とを、それぞれ単独で使用するか、または併用するかを選択してエンジンをクランキングするハイブリッド車両の制御装置が知られている（例えば、特許文献２参照）。   In addition, in a vehicle that is started by a starter motor that is a starter when the engine is started by operating a key and is always assisted by a motor generator that is a generator motor, the starter motor and the motor generator are There is known a control device for a hybrid vehicle that cranks an engine by selecting whether to use it alone or in combination (see, for example, Patent Document 2).

なお、特許文献２に記載のハイブリッド車両の制御装置では、スタータモータと電動発電機とを併用してエンジンをクランキングする場合に、スタータモータを駆動させるとともに、その後エンジン回転数が設定回転数以上になったら、電動発電機の駆動を開始させている。また、電動発電機のみでエンジンを再始動する場合には、電動発電機のモータ出力値を、定格性能を越えた値に設定している。   In the hybrid vehicle control device described in Patent Document 2, when the engine is cranked using both the starter motor and the motor generator, the starter motor is driven, and then the engine speed is equal to or higher than the set speed.

しかしながら、従来技術には、以下のような課題がある。
すなわち、従来のエンジン始動装置では、エンジンの各始動状況において、発電電動機によるエンジンのクランキングと、スタータによるエンジンのクランキングと、発電電動機およびスタータの両方によるエンジンのクランキングとを、エンジンの水温や電源電圧等に基づいて、選択することになっている。 However, the prior art has the following problems.
That is, in the conventional engine starter, in each engine start situation, the engine cranking by the generator motor, the engine cranking by the starter, and the engine cranking by both the generator motor and the starter are combined with the engine water temperature. It is to be selected based on the power supply voltage or the like.

例えば、特許文献１に記載されたエンジンの始動制御装置では、エンジンの水温に応じて、エンジン始動方法を選択している。つまり、運転者の始動操作によりエンジンを始動する初期始動においても、エンジンの水温をモニタして、発電電動機でクランキングするか、スタータでクランキングするか、または発電電動機とスタータとを併用してクランキングするかを選択することになる。   For example, in the engine start control device described in Patent Document 1, an engine start method is selected according to the engine water temperature. In other words, even at the initial start when the engine is started by the driver's start operation, the engine water temperature is monitored and cranked with a generator motor, cranked with a starter, or a generator motor and a starter are used in combination. You will choose whether to crank.

そのため、エンジンの始動前に始動方法を判断する制御が必要になるとともに、判断材料となる水温等を検知するセンサ等が必要になり、エンジン始動装置が複雑化し、高コスト化するという問題がある。   Therefore, it is necessary to perform control for determining a starting method before starting the engine, and a sensor for detecting a water temperature or the like as a determination material is required, which causes a problem that the engine starting device becomes complicated and the cost is increased. .

また、特許文献２に記載されたハイブリッド車両の制御装置では、初期始動の場合には、スタータで起動するとともに発電電動機によって常時アシストすることになっているが、エンジンの再始動時には、エンジンの水温や電源電圧に基づいて、スタータと発電電動機とを、それぞれ単独で使用するか、または併用するかを選択することになる。   In the hybrid vehicle control device described in Patent Document 2, in the case of initial start, the starter is started and the motor is always assisted by the generator motor. Whether the starter and the generator motor are used alone or in combination is selected based on the power supply voltage.

そのため、エンジンの再始動前に始動方法を判断する制御が必要になるとともに、判断材料となる水温等を検知するセンサ等が必要になり、エンジン始動装置が複雑化し、高コスト化するという問題がある。   For this reason, it is necessary to perform control for determining the starting method before restarting the engine, and a sensor for detecting the water temperature or the like as a determination material is required, which complicates the engine starting device and increases costs. is there.

この発明は、上記のような課題を解決するためになされたものであり、エンジン始動時における発電電動機およびスタータの使用方法を統一することにより、簡素な構成かつ低コストで、エンジン始動性を確保することができるエンジン始動装置を得ることを目的とする。   The present invention has been made to solve the above-described problems. By unifying the method of using the generator motor and starter at the time of starting the engine, the engine startability can be secured with a simple structure and at a low cost. It is an object of the present invention to obtain an engine starter that can be used.

この発明に係るエンジン始動装置は、エンジンのクランク軸に連結された発電電動機と、エンジンの始動時に、クランク軸に設けられたリングギヤにピニオンを噛合させるスタータと、エンジンが始動したか否かを判定する判定部と、を備え、エンジンの始動開始時に、発電電動機およびスタータのいずれか一方でエンジンをクランキングするとともに、エンジンの始動開始から設定時間が経過した時点で、判定部によりエンジンが始動していないと判定された場合に、発電電動機およびスタータの両方でエンジンを併用クランキングするものである。   An engine starter according to the present invention determines a generator motor connected to a crankshaft of an engine, a starter that meshes a pinion with a ring gear provided on the crankshaft when the engine is started, and whether the engine has started A determination unit configured to crank the engine at one of the generator motor and the starter at the start of engine start, and when the set time has elapsed from the start of engine start, the engine is started by the determination unit. When it is determined that the engine is not in use, both the generator motor and the starter crank the engine together.

この発明に係るエンジン始動装置によれば、エンジンの始動開始時に、発電電動機およびスタータのいずれか一方でエンジンをクランキングするとともに、エンジンの始動開始から設定時間が経過した時点で、判定部によりエンジンが始動していないと判定された場合に、発電電動機およびスタータの両方でエンジンを併用クランキングする。
そのため、エンジン始動時における発電電動機およびスタータの使用方法を統一することにより、簡素な構成かつ低コストで、エンジン始動性を確保することができる。 According to the engine starter of the present invention, at the start of engine start, the engine is cranked by either the generator motor or the starter, and when the set time has elapsed from the start of engine start, When it is determined that the engine has not started, the engine is combined and cranked by both the generator motor and the starter.
Therefore, by unifying the usage methods of the generator motor and the starter at the time of starting the engine, the engine startability can be ensured with a simple configuration and low cost.

この発明の実施の形態１に係るエンジン始動装置が搭載された車両の概略構成を示すブロック図である。1 is a block diagram showing a schematic configuration of a vehicle equipped with an engine starter according to Embodiment 1 of the present invention.

以下、この発明に係るエンジン始動装置の好適な実施の形態につき図面を用いて説明するが、各図において同一、または相当する部分については、同一符号を付して説明する。   Hereinafter, preferred embodiments of an engine starter according to the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts will be described with the same reference numerals.

実施の形態１．
図１は、この発明の実施の形態１に係るエンジン始動装置が搭載された車両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１は、エンジン自動停止再始動制御のエンジン停止、またはエンジン再始動を判断する機能を含み、エンジン１の制御を行うエンジン制御装置５により駆動制御されている。以下、エンジン制御装置５のことをエンジンＥＣＵ５と称する。 Embodiment 1 FIG.
1 is a block diagram showing a schematic configuration of a vehicle on which an engine starter according to Embodiment 1 of the present invention is mounted. In FIG. 1, the engine 1 includes a function of determining engine stop or engine restart of engine automatic stop / restart control, and is driven and controlled by an engine control device 5 that controls the engine 1. Hereinafter, the engine control device 5 is referred to as an engine ECU 5.

エンジン１のクランク軸１１には、ベルト１２を介して発電電動機２が常時連結されている。また、スタータ３の回転トルクの出力部となるピニオン３１は、クランク軸１１と一体となったリングギヤ１３に着脱可能な状態で設けられ、回転トルクを伝達する。   A generator motor 2 is always connected to the crankshaft 11 of the engine 1 via a belt 12. Further, the pinion 31 serving as an output part of the rotational torque of the starter 3 is provided in a detachable state on the ring gear 13 integrated with the crankshaft 11 and transmits the rotational torque.

発電電動機２には、電力変換装置２１が接続されている。また、電力変換装置２１は、バッテリ４と、発電電動機２の回生および力行の制御を行う発電電動機制御回路２２とに接続されている。以下、発電電動機制御回路２２のことをＭＧ制御回路２２と称する。   A power converter 21 is connected to the generator motor 2. The power converter 21 is connected to the battery 4 and a generator motor control circuit 22 that controls regeneration and power running of the generator motor 2. Hereinafter, the generator motor control circuit 22 is referred to as an MG control circuit 22.

スタータ３は、スタータ３に電力の供給を行うための電気接点の開閉機能を持った電磁スイッチ３２を備えている。また、電磁スイッチ３２は、バッテリ４に接続されている。なお、ＭＧ制御回路２２の入力端子および電磁スイッチ３２の励磁端子には、それぞれエンジン始動時の信号が入力される。   The starter 3 includes an electromagnetic switch 32 having an electrical contact opening / closing function for supplying power to the starter 3. The electromagnetic switch 32 is connected to the battery 4. A signal for starting the engine is input to the input terminal of the MG control circuit 22 and the excitation terminal of the electromagnetic switch 32, respectively.

さらに、エンジン１は、クランク軸１１の回転角度を検出する図示しないクランク角センサを備えており、クランク角センサからのクランク角信号は、エンジンＥＣＵ５に送信され演算されて、エンジン１のクランク軸１１の回転速度を導出する。   Further, the engine 1 includes a crank angle sensor (not shown) that detects the rotation angle of the crankshaft 11, and a crank angle signal from the crank angle sensor is transmitted to the engine ECU 5 and calculated, and the crankshaft 11 of the engine 1 is calculated. The rotational speed of is derived.

次に、発電電動機２の機能について説明する。発電電動機２は、回生である発電の機能と、力行であるモータ駆動の機能との２つの機能を有している。ここで、回生時は、エンジン１が稼働状態の場合であり、発電電動機２は、エンジン１の回転トルクにより、クランク軸１１からベルト１２を介して常時回転している状態で、ＭＧ制御回路２２によって制御される電力変換装置２１で発電電力を整流して、バッテリ４に充電を行っている。   Next, the function of the generator motor 2 will be described. The generator motor 2 has two functions: a power generation function that is regenerative and a motor drive function that is power running. Here, the regeneration is a case where the engine 1 is in an operating state, and the generator motor 2 is constantly rotating from the crankshaft 11 via the belt 12 by the rotational torque of the engine 1, and the MG control circuit 22. The battery 4 is charged by rectifying the generated power by the power converter 21 controlled by the above.

また、力行時は、エンジン１に回転トルクを供給する場合であり、発電電動機２は、バッテリ４の電力を使用し、ＭＧ制御回路２２によって制御される電力変換装置２１を介して電力供給を受け、モータとして駆動される。さらに、ベルト１２を介してクランク軸１１に回転トルクが伝達され、エンジン１が駆動される。   The power running is a case where rotational torque is supplied to the engine 1, and the generator motor 2 uses the power of the battery 4 and receives power supply via the power converter 21 controlled by the MG control circuit 22. Driven as a motor. Further, the rotational torque is transmitted to the crankshaft 11 via the belt 12, and the engine 1 is driven.

なお、発電電動機２は、エンジン１の始動が完了した後には、力行から回生へと切り替わる。また、エンジン１に回転トルクを供給する場合には、エンジン１のクランキング時と、稼働状態のエンジン１の発生トルクを補うトルクアシスト時と、エンジン１が停止していても発電電動機２のみで車両を移動させる電動走行時とがある。   The generator motor 2 is switched from power running to regeneration after the start of the engine 1 is completed. In addition, when the rotational torque is supplied to the engine 1, only the generator motor 2 is used when the engine 1 is cranked, when the torque assist is made up for the generated torque of the engine 1 in an operating state, and even when the engine 1 is stopped. There are times when the vehicle travels electrically.

続いて、スタータ３の機能について説明する。スタータ３は、エンジン１のクランキング時に使用され、電磁スイッチ３２の励磁端子に電圧が印加されることにより、電磁スイッチ３２の電気接点が閉路されて、スタータ３のモータ部に電力が供給されるとともに、ピニオン３１がリングギヤ１３側へ移動する。その後、リングギヤ１３とピニオン３１とが噛み合うことにより、スタータ３のモータ部で発生する回転トルクが、クランク軸１１に伝達され、エンジン１を駆動する。   Next, the function of the starter 3 will be described. The starter 3 is used at the time of cranking the engine 1. When a voltage is applied to the excitation terminal of the electromagnetic switch 32, the electrical contact of the electromagnetic switch 32 is closed and power is supplied to the motor unit of the starter 3. At the same time, the pinion 31 moves to the ring gear 13 side. Thereafter, when the ring gear 13 and the pinion 31 are engaged with each other, the rotational torque generated in the motor portion of the starter 3 is transmitted to the crankshaft 11 to drive the engine 1.

なお、モータ部の出力軸とピニオン３１を含むピニオン移動体とは、モータ部が回転駆動したときに、ピニオン移動体が静止位置からリングギヤ１３側への推進力が発生する角度を持ったヘリカルスプラインで係合されている。   The pinion moving body including the output shaft of the motor unit and the pinion 31 is a helical spline having an angle at which a propulsive force is generated from the stationary position to the ring gear 13 when the motor unit is driven to rotate. Is engaged.

また、エンジン１側でスタータ３の回転トルクが不要となった場合には、励磁端子の電圧の印加が解消される。これにより、ピニオン３１がリングギヤ１３と噛み合っている状態が解消されるとともに、電磁スイッチ３２の電気接点が開路されて、スタータ３のモータ部への電力供給がなくなる。   Further, when the rotational torque of the starter 3 becomes unnecessary on the engine 1 side, the application of the voltage at the excitation terminal is canceled. As a result, the state in which the pinion 31 is engaged with the ring gear 13 is eliminated, and the electrical contact of the electromagnetic switch 32 is opened, so that power supply to the motor portion of the starter 3 is lost.

次に、この発明の実施の形態１に係るエンジン始動装置において、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングして、エンジン１を始動させる一連の動作について説明する。   Next, in the engine starter according to Embodiment 1 of the present invention, a series of operations for starting the engine 1 by cranking the engine 1 together with both the generator motor 2 and the starter 3 will be described.

発電電動機２およびスタータ３の両方でエンジン１を始動する場合には、所定の電気信号により、電磁スイッチ３２の励磁端子に電圧が印加され、電磁スイッチ３２を駆動して電気接点を閉路する。この結果、モータ回路に通電がなされることにより、電流がスタータ３のモータ部に供給され、モータ部に回転トルクが発生してスタータ３が起動される。   When the engine 1 is started by both the generator motor 2 and the starter 3, a voltage is applied to the excitation terminal of the electromagnetic switch 32 by a predetermined electrical signal, and the electromagnetic switch 32 is driven to close the electrical contact. As a result, when the motor circuit is energized, an electric current is supplied to the motor unit of the starter 3, and rotational torque is generated in the motor unit to start the starter 3.

また、電磁スイッチ３２を駆動することによって、ピニオン３１が、リングギヤ１３に噛み合う位置に移動する。その結果、モータ部の回転トルクが、噛み合ったピニオン３１とリングギヤ１３とを介してクランク軸１１に伝達され、エンジン１をクランキングすることとなる。その後、燃料噴射が開始される。   Further, by driving the electromagnetic switch 32, the pinion 31 moves to a position where it engages with the ring gear 13. As a result, the rotational torque of the motor unit is transmitted to the crankshaft 11 through the meshed pinion 31 and the ring gear 13, and the engine 1 is cranked. Thereafter, fuel injection is started.

さらに、ＭＧ制御回路２２へも電気信号が伝送され、ＭＧ制御回路２２は、発電電動機２を力行で起動するために、バッテリ４の電力を使用し、ＭＧ制御回路２２によって制御される電力変換装置２１を介して、発電電動機２に電力を供給する。この結果、発電電動機２は、力行駆動され、ベルト１２を介してクランク軸１１に回転トルクを伝達することで、エンジン１をクランキングする。   Furthermore, an electric signal is also transmitted to the MG control circuit 22, and the MG control circuit 22 uses the power of the battery 4 to start the generator motor 2 by powering and is controlled by the MG control circuit 22. Electric power is supplied to the generator motor 2 via 21. As a result, the generator motor 2 is driven by power running and transmits the rotational torque to the crankshaft 11 via the belt 12 to crank the engine 1.

このようなエンジン１のクランキング中、エンジンＥＣＵ５は、クランク角センサからのクランク角信号により得られる現在のクランク角度、およびクランク角信号の周期に基づいて、エンジン１の回転速度、つまりリングギヤ１３の回転速度を演算して、監視している。   During the cranking of the engine 1, the engine ECU 5 determines the rotational speed of the engine 1, that is, the ring gear 13 based on the current crank angle obtained from the crank angle signal from the crank angle sensor and the cycle of the crank angle signal. The rotation speed is calculated and monitored.

このとき、エンジンＥＣＵ５は、エンジン１の回転速度に基づいて、エンジン１の回転速度があらかじめ設定された回転速度以上となり、エンジン１が完爆したか否か、すなわちエンジン１が稼働状態になり始動が完了したか否かの判定を行う。エンジン１が完爆していない場合には、エンジンＥＣＵ５は、エンジン１の完爆の判定が行われるまで、状態を維持して待機する。   At this time, the engine ECU 5 starts based on the rotational speed of the engine 1 to determine whether or not the rotational speed of the engine 1 is equal to or higher than a predetermined rotational speed and the engine 1 has completely exploded, that is, the engine 1 is in an operating state and started. It is determined whether or not is completed. If the engine 1 is not completely exploded, the engine ECU 5 stands by while maintaining the state until the determination of the complete explosion of the engine 1 is made.

一方、判定の結果、エンジン１が完爆している場合には、エンジンＥＣＵ５は、スタータ３を停止させる。すなわち、ピニオン３１がリングギヤ１３と噛み合っている状態が解消されるとともに、電磁スイッチ３２の電気接点が開路されて、スタータ３のモータ部への電力供給がなくなる。また同時に、エンジンＥＣＵ５は、ＭＧ制御回路２２による発電電動機２への電力供給を停止し、力行を停止させる。   On the other hand, as a result of the determination, when the engine 1 is completely exploded, the engine ECU 5 stops the starter 3. That is, the state in which the pinion 31 is meshed with the ring gear 13 is eliminated, and the electrical contact of the electromagnetic switch 32 is opened, so that power supply to the motor unit of the starter 3 is lost. At the same time, the engine ECU 5 stops the power supply to the generator motor 2 by the MG control circuit 22 and stops the power running.

これら一連の動作により、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングして、エンジン１を始動させる処理が終了する。   With these series of operations, the process of cranking the engine 1 together with both the generator motor 2 and the starter 3 and starting the engine 1 is completed.

なお、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングする場合に、１つの電気信号を発電電動機２およびスタータ３に直列に伝送してもよいし、並列に伝送してもよい。発電電動機２およびスタータ３に電気信号を送信するタイミングを同時にできれば、運転者の始動操作によりエンジン１を始動する初期始動においても、スタータ３の電磁スイッチ３２へ印加する電圧を、電気信号として他の制御機能を介さずＭＧ制御回路２２に送信することにより、併用クランキングを実施することが可能となる。   When cranking the engine 1 with both the generator motor 2 and the starter 3, one electric signal may be transmitted in series to the generator motor 2 and the starter 3, or may be transmitted in parallel. If the timing for transmitting the electrical signal to the generator motor 2 and the starter 3 can be made at the same time, the voltage applied to the electromagnetic switch 32 of the starter 3 as another electrical signal can be used as an electrical signal even in the initial start of starting the engine 1 by the driver's start operation. By transmitting to the MG control circuit 22 without passing through the control function, the combined cranking can be performed.

さらに、ピニオン３１のリングギヤ１３側端面と、非トルク伝達側の歯面との間には、歯面に沿った曲面形状として歯面面取り部を設け、さらに、ピニオン３１の歯先外径部には、歯先外径に沿って、歯先面取り部が設けた機構であってもよい。この場合、歯面面取り部は、非トルク伝達側の歯面に沿った曲面で形成されているため、軸方向に垂直な断面で見たときには、リングギヤ１３の歯と、ピニオン３１の歯とが、常にかみ合った状態と同じである。   Further, a tooth chamfered portion is provided as a curved shape along the tooth surface between the end surface of the pinion 31 on the ring gear 13 side and the tooth surface on the non-torque transmission side, and the tooth tip outer diameter portion of the pinion 31 is further provided. May be a mechanism provided with a chamfered portion of the tooth tip along the outer diameter of the tooth tip. In this case, since the tooth chamfered portion is formed by a curved surface along the tooth surface on the non-torque transmission side, when viewed in a cross section perpendicular to the axial direction, the teeth of the ring gear 13 and the teeth of the pinion 31 are Is always the same as the engaged state.

歯同士が噛み合った状態と同じでない場合には、リングギヤ１３とピニオン３１のそれぞれの歯の速度ベクトルが異なる。このため、結果として、接触位置が軸方向へ振れることになり、安定した回転力を伝えられないだけでなく、はじかれる力になる場合もあり、不安定な噛合い状態となる。   When the teeth are not the same as the meshed state, the tooth speed vectors of the ring gear 13 and the pinion 31 are different. As a result, the contact position swings in the axial direction, and not only a stable rotational force cannot be transmitted, but also a repelling force may occur, resulting in an unstable meshing state.

つまり、ピニオン３１のリングギヤ１３側端面と、非トルク伝達側の歯面との間に、歯面に沿った曲面形状として歯面面取り部を設けることにより、先に発電電動機２が回転を開始しても、安定した噛合いが可能になる。   That is, by providing a tooth chamfered portion as a curved surface shape along the tooth surface between the ring gear 13 side end surface of the pinion 31 and the tooth surface on the non-torque transmission side, the generator motor 2 starts rotating first. However, stable engagement is possible.

続いて、この発明の実施の形態１に係るエンジン始動装置において、スタータ３でエンジン１をクランキングして、エンジン１を始動させる一連の動作について説明する。   Next, a series of operations for starting the engine 1 by cranking the engine 1 with the starter 3 in the engine starting device according to Embodiment 1 of the present invention will be described.

スタータ３でエンジン１を始動する場合に、例えば運転者による始動操作が実施されると、所定の電気信号により、電磁スイッチ３２の励磁端子に電圧が印加され、電磁スイッチ３２を駆動して電気接点を閉路する。この結果、モータ回路に通電がなされることにより、電流がスタータ３のモータ部に供給され、モータ部に回転トルクが発生してスタータ３が起動される。   When starting the engine 1 with the starter 3, for example, when a start operation is performed by the driver, a voltage is applied to the excitation terminal of the electromagnetic switch 32 by a predetermined electrical signal, and the electromagnetic switch 32 is driven to make an electrical contact. Is closed. As a result, when the motor circuit is energized, an electric current is supplied to the motor unit of the starter 3, and rotational torque is generated in the motor unit to start the starter 3.

また、電磁スイッチ３２を駆動することによって、ピニオン３１が、リングギヤ１３に噛み合う位置に移動する。その結果、モータ部の回転トルクが、噛み合ったピニオン３１とリングギヤ１３とを介してクランク軸１１に伝達され、エンジン１をクランキングすることとなる。その後、燃料噴射が開始される。   Further, by driving the electromagnetic switch 32, the pinion 31 moves to a position where it engages with the ring gear 13. As a result, the rotational torque of the motor unit is transmitted to the crankshaft 11 through the meshed pinion 31 and the ring gear 13, and the engine 1 is cranked. Thereafter, fuel injection is started.

このようなエンジン１のクランキング中、エンジンＥＣＵ５は、クランク角センサからのクランク角信号により得られる現在のクランク角度、およびクランク角信号の周期に基づいて、エンジン１の回転速度、つまりリングギヤ１３の回転速度を演算して、監視している。   During the cranking of the engine 1, the engine ECU 5 determines the rotational speed of the engine 1, that is, the ring gear 13 based on the current crank angle obtained from the crank angle signal from the crank angle sensor and the cycle of the crank angle signal. The rotation speed is calculated and monitored.

このとき、エンジンＥＣＵ５は、エンジン１の回転速度に基づいて、エンジン１の回転速度があらかじめ設定された回転速度以上となり、エンジン１が完爆したか否か、すなわちエンジン１が稼働状態になり始動が完了したか否かの判定を行う。エンジン１が完爆していない場合には、エンジンＥＣＵ５は、エンジン１の完爆の判定が行われるまで、状態を維持して待機する。   At this time, the engine ECU 5 starts based on the rotational speed of the engine 1 to determine whether or not the rotational speed of the engine 1 is equal to or higher than a predetermined rotational speed and the engine 1 has completely exploded, that is, the engine 1 is in an operating state and started. It is determined whether or not is completed. If the engine 1 is not completely exploded, the engine ECU 5 stands by while maintaining the state until the determination of the complete explosion of the engine 1 is made.

一方、判定の結果、エンジン１が完爆している場合には、エンジンＥＣＵ５は、スタータ３を停止させる。すなわち、ピニオン３１がリングギヤ１３と噛み合っている状態が解消されるとともに、電磁スイッチ３２の電気接点が開路されて、スタータ３のモータ部への電力供給がなくなる。   On the other hand, as a result of the determination, when the engine 1 is completely exploded, the engine ECU 5 stops the starter 3. That is, the state in which the pinion 31 is meshed with the ring gear 13 is eliminated, and the electrical contact of the electromagnetic switch 32 is opened, so that power supply to the motor unit of the starter 3 is lost.

なお、完爆の判定を待って、状態を維持した状態が、任意の設定時間以上継続した場合には、エンジンＥＣＵ５は、スタータ３でのクランキングを停止し、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングして、エンジン１を始動させる。   If the state of maintaining the state after waiting for the determination of complete explosion continues for an arbitrary set time or longer, the engine ECU 5 stops the cranking in the starter 3 and both the generator motor 2 and the starter 3 are stopped. Then, the engine 1 is cranked together and the engine 1 is started.

つまり、スタータ３でのクランキングで、設定時間内にエンジン１が稼働状態にならなかった場合には、その要因に関係なく、発電電動機２およびスタータ３の両方を用いた併用クランキングのみを実施する。   In other words, if the engine 1 is not in operation within the set time by cranking with the starter 3, only combined cranking using both the generator motor 2 and the starter 3 is performed regardless of the factor. To do.

次に、この発明の実施の形態１に係るエンジン始動装置において、発電電動機２でエンジン１をクランキングして、エンジン１を始動させる一連の動作について説明する。   Next, a series of operations for starting the engine 1 by cranking the engine 1 with the generator motor 2 in the engine starting device according to Embodiment 1 of the present invention will be described.

エンジン自動停止再始動制御によりエンジン１への燃料供給が停止され、その後再始動条件が成立すると、エンジンＥＣＵ５は、起動の電気信号をＭＧ制御回路２２に送信する。起動の電気信号を受けたＭＧ制御回路２２は、バッテリ４の電力を使用し、電力変換装置２１を介して、発電電動機２に電力を供給する。この結果、発電電動機２は、力行駆動され、ベルト１２を介してクランク軸１１に回転トルクを伝達することで、エンジン１をクランキングする。   When the fuel supply to the engine 1 is stopped by the engine automatic stop / restart control and then the restart condition is satisfied, the engine ECU 5 transmits an electric signal for starting to the MG control circuit 22. The MG control circuit 22 that has received the activation electrical signal uses the power of the battery 4 and supplies power to the generator motor 2 via the power converter 21. As a result, the generator motor 2 is driven by power running and transmits the rotational torque to the crankshaft 11 via the belt 12 to crank the engine 1.

このようなエンジン１のクランキング中、初期始動と同様に、エンジンＥＣＵ５は、クランク角センサからのクランク角信号により得られる現在のクランク角度、およびクランク角信号の周期に基づいて、エンジン１の回転速度、つまりリングギヤ１３の回転速度を演算して、監視している。   During cranking of the engine 1, as in the initial start, the engine ECU 5 rotates the engine 1 based on the current crank angle obtained from the crank angle signal from the crank angle sensor and the cycle of the crank angle signal. The speed, that is, the rotational speed of the ring gear 13 is calculated and monitored.

このとき、エンジンＥＣＵ５は、エンジン１の回転速度に基づいて、エンジン１の回転速度があらかじめ設定された回転速度以上となり、エンジン１が完爆したか否か、すなわちエンジン１が稼働状態になり始動が完了したか否かの判定を行う。エンジン１が完爆していない場合には、エンジンＥＣＵ５は、エンジン１の完爆の判定が行われるまで、状態を維持して待機する。   At this time, the engine ECU 5 starts based on the rotational speed of the engine 1 to determine whether or not the rotational speed of the engine 1 is equal to or higher than a predetermined rotational speed and the engine 1 has completely exploded, that is, the engine 1 is in an operating state and started. It is determined whether or not is completed. If the engine 1 is not completely exploded, the engine ECU 5 stands by while maintaining the state until the determination of the complete explosion of the engine 1 is made.

一方、判定の結果、エンジン１が完爆している場合には、エンジンＥＣＵ５は、ＭＧ制御回路２２による発電電動機２への電力供給を停止し、力行を停止させる。   On the other hand, as a result of the determination, when the engine 1 is completely exploded, the engine ECU 5 stops the power supply to the generator motor 2 by the MG control circuit 22 and stops the power running.

なお、完爆の判定を待って、状態を維持した状態が、任意の設定時間以上継続した場合には、エンジンＥＣＵ５は、発電電動機２でのクランキングを停止し、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングして、エンジン１を始動させる。   When the state of maintaining the state after waiting for the complete explosion is continued for an arbitrary set time or longer, the engine ECU 5 stops the cranking in the generator motor 2 and the generator motor 2 and the starter 3 Both engines 1 are cranked together, and the engine 1 is started.

つまり、発電電動機２でのクランキングで、設定時間内にエンジン１が稼働状態にならなかった場合には、その要因に関係なく、発電電動機２およびスタータ３の両方を用いた併用クランキングのみを実施する。   That is, if the engine 1 is not in operation within the set time by cranking with the generator motor 2, only the combined cranking using both the generator motor 2 and the starter 3 is performed regardless of the factor. carry out.

このように構成されたエンジン始動装置によれば、発電電動機２とスタータ３とをそれぞれ単独で使用してエンジン始動を実施し、設定時間内にエンジン１が始動しなかった場合には、エンジン１の始動に失敗したと判断して、その要因に関係なく、発電電動機２およびスタータ３の両方を用いた併用クランキングのみを実施することになる。   According to the engine starter configured as described above, the engine 1 is started using the generator motor 2 and the starter 3 independently, and if the engine 1 does not start within the set time, the engine 1 Therefore, only the combined cranking using both the generator motor 2 and the starter 3 is performed regardless of the factor.

つまり、エンジン始動に失敗した場合の次の始動を、発電電動機２およびスタータ３の両方を用いた併用クランキングとすることで、発電電動機２のみまたはスタータ３のみでのクランキングから、発電電動機２およびスタータ３の両方の回転トルクでのクランクキングとなり、良好な始動性を確保することができる。   That is, the next start when the engine start fails is the combined cranking using both the generator motor 2 and the starter 3, so that the generator motor 2 can be changed from the cranking of the generator motor 2 alone or the starter 3 alone. In addition, cranking is performed with the rotational torques of both the starter 3 and the starter 3, and good startability can be ensured.

本来、エンジン１の各始動状況に応じて、発電電動機２やスタータ３の仕様が決められているため、エンジン１の始動前に、始動方法の選択を行わず、発電電動機２とスタータ３とをそれぞれ単独で用いてエンジン１を始動するか、または発電電動機２およびスタータ３の両方を用いてエンジン１を始動するかを固定化することで、仮にエンジン始動に失敗した場合であっても、次の始動の始動性を確保することができる。   Originally, the specifications of the generator motor 2 and the starter 3 are determined according to each start situation of the engine 1, so that the starter method is not selected before starting the engine 1, and the generator motor 2 and the starter 3 are connected. Even if the engine has failed to start by fixing whether the engine 1 is started using each of them or the engine 1 is started using both the generator motor 2 and the starter 3, The startability of the starting can be ensured.

また、始動方法の選択を行わないことにより、始動方法の選択を行うための複雑な制御や判断材料となるセンサを必要とせず、低コストでエンジン始動性を確保することができる。さらに、エンジン１の各始動状況に応じて、始動するときの駆動力が固定化されているため、運転者への違和感も軽減される。   Further, by not selecting the starting method, complicated starting control for selecting the starting method and a sensor as a judgment material are not required, and the engine startability can be ensured at low cost. Further, since the driving force at the time of starting is fixed in accordance with each starting state of the engine 1, the uncomfortable feeling to the driver is also reduced.

なお、エンジン自動停止再始動制御によるエンジン自動停止後の再始動においては、発電電動機２でのクランキングを実施することとしてもよい。つまり、エンジン１の暖機状態である再始動では、エンジン１の始動に必要なフリクショントルクが低温時に比べて小さいため、毎回始動方法を判断するのではなく、発電電動機２のみでのクランキングを行い、再始動に失敗したときにのみ、再々始動として併用クランキングを実施するとしてもよい。   In the restart after the engine automatic stop by the engine automatic stop / restart control, cranking by the generator motor 2 may be performed. In other words, when the engine 1 is in a warm-up state, the friction torque required to start the engine 1 is smaller than when the engine 1 is at a low temperature. Therefore, instead of determining the starting method every time, the cranking only with the generator motor 2 is performed. It is possible to perform combined cranking as re-starting only when restarting fails.

この場合には、再始動において、発電電動機２のみの決まった再始動を実施するため、複雑な制御が不要となり、迅速にエンジン始動を実施することができる。また、発電電動機２は、スタータ３に比べて高回転までクランキングすることが可能であるため、迅速に、かつ静かにエンジン１を始動することができる。   In this case, since only the generator motor 2 is restarted in the restart, complicated control is not required, and the engine can be started quickly. Moreover, since the generator motor 2 can crank up to a higher speed than the starter 3, the engine 1 can be started quickly and silently.

以上のように、実施の形態１によれば、エンジン１の始動開始時に、発電電動機２およびスタータ３のいずれか一方でエンジン１をクランキングするとともに、エンジン１の始動開始から設定時間が経過した時点で、判定部によりエンジン１が始動していないと判定された場合に、発電電動機２およびスタータ３の両方でエンジン１を併用クランキングする。
そのため、エンジン始動時における発電電動機２およびスタータ３の使用方法を統一することにより、簡素な構成かつ低コストで、エンジン始動性を確保することができる。 As described above, according to the first embodiment, at the start of starting the engine 1, the engine 1 is cranked by either the generator motor 2 or the starter 3, and the set time has elapsed since the start of the engine 1 is started. When the determination unit determines that the engine 1 has not started at the time, both the generator motor 2 and the starter 3 crank the engine 1 together.
Therefore, by unifying the usage methods of the generator motor 2 and the starter 3 when starting the engine, it is possible to ensure engine startability with a simple configuration and low cost.

実施の形態２．
この発明の実施の形態２では、複数のバッテリを搭載した車両におけるバッテリの使用方法について説明する。 Embodiment 2. FIG.
In the second embodiment of the present invention, a method of using a battery in a vehicle equipped with a plurality of batteries will be described.

上記実施の形態１では、車両の電源であるバッテリ４を１つのバッテリとして説明してきたが、これに限定されず、複数のバッテリで構成されていてもよい。また、発電電動機２およびスタータ３のそれぞれに別のバッテリが接続されていてもよく、始動用のバッテリとは別に、車両に搭載された電気機器用のバッテリが設けられていてもよい。さらに、例えば発電電動機２の動作電圧が２４Ｖでスタータ３の動作電圧が１２Ｖとなるような、異なる電圧系のバッテリが設けられていてもよく、バッテリの構成は規制されるものではない。   In the first embodiment, the battery 4 as the power source of the vehicle has been described as one battery. However, the present invention is not limited to this, and the battery 4 may be composed of a plurality of batteries. Further, a separate battery may be connected to each of the generator motor 2 and the starter 3, and a battery for an electric device mounted on the vehicle may be provided separately from the starting battery. Further, for example, a battery of a different voltage system may be provided such that the operating voltage of the generator motor 2 is 24V and the operating voltage of the starter 3 is 12V, and the configuration of the battery is not restricted.

これにより、エンジン１の始動開始から設定時間内にエンジン１が稼働状態にならなかった場合には、そのとき使用していた電力よりも多くの電力で発電電動機２およびスタータ３を起動させて、エンジン１をクランキングすることができる。   Thereby, when the engine 1 is not in an operating state within a set time from the start of starting the engine 1, the generator motor 2 and the starter 3 are started with more electric power than that used at that time, The engine 1 can be cranked.

なお、複数個のバッテリがすべて同じ電圧系である場合には、最大容量のバッテリの電力を使用して始動してもよいし、複数個のバッテリを使用して始動してもよい。複数個のバッテリの中に最大容量のバッテリを含めると、さらに始動性を向上させることができる。   When all of the plurality of batteries have the same voltage system, the battery may be started using the maximum capacity battery power, or may be started using a plurality of batteries. When a battery with the maximum capacity is included in the plurality of batteries, the startability can be further improved.

また、複数個のバッテリの電圧系が２種類以上ある場合、例えば発電電動機２が２４Ｖや４８Ｖ系であり、スタータ３が１２Ｖ系であるときには、高電圧のバッテリの電力をスタータ３に使用してエンジン１を始動してもよいし、高電圧のバッテリを含み、複数個のバッテリの電力を一度に使用してもよい。   Further, when there are two or more voltage systems of a plurality of batteries, for example, when the generator motor 2 is a 24V or 48V system and the starter 3 is a 12V system, the power of the high voltage battery is used for the starter 3. The engine 1 may be started, or a high voltage battery may be used, and the power of a plurality of batteries may be used at once.

このとき、複数個のバッテリを使用する場合は、ＤＣ／ＤＣコンバータ等の電圧変換装置を介して、低電圧のバッテリを同時に使用することも可能である。   At this time, when using a plurality of batteries, it is also possible to use low voltage batteries simultaneously through a voltage converter such as a DC / DC converter.

このような始動方法とすることで、例えば発電電動機２の出力トルクの低下や発電電動機２が使用できない状態になっていたとしても、可能な限り多くの電力でスタータ３を駆動することにより、スタータ３が定格出力を超えた出力を発生することができ、エンジン１の始動性を確保することができる。また、逆にスタータ３が同様の状態であった場合でも、発電電動機２が定格出力を超えた出力を発生することができ、エンジン１の始動性を確保することができる。   By adopting such a starting method, for example, even if the output torque of the generator motor 2 is reduced or the generator motor 2 cannot be used, the starter 3 is driven with as much power as possible. 3 can generate an output exceeding the rated output, and the startability of the engine 1 can be ensured. Conversely, even when the starter 3 is in the same state, the generator motor 2 can generate an output exceeding the rated output, and the startability of the engine 1 can be ensured.

ここで、この発明の実施の形態２は、発電電動機２およびスタータ３をそれぞれ単独で使用する場合だけでなく、発電電動機２およびスタータ３を両方使用する場合にエンジン始動に失敗したときにも適用することができる。   Here, the second embodiment of the present invention is applied not only when the generator motor 2 and the starter 3 are used alone, but also when the engine start fails when both the generator motor 2 and the starter 3 are used. can do.

なお、上記実施の形態１、２において、発電電動機２は、エンジン１のクランク軸１１にベルト１２で常時連結され、回生および力行の機能を合わせ持った発電電動機２として説明してきたが、クランク軸１１に直結していてもよいし、電磁クラッチ等を介して連結していてもよく、エンジン１をクランキングできる電動機の機能をもったものであれば、同様の効果を得ることができる。   In the first and second embodiments, the generator motor 2 has been described as the generator motor 2 that is always connected to the crankshaft 11 of the engine 1 by the belt 12 and has both regeneration and power running functions. 11 may be directly connected to each other, may be connected via an electromagnetic clutch or the like, and the same effect can be obtained as long as it has a function of an electric motor capable of cranking the engine 1.
