　図２は、本開示の一実施形態に係る電子制御ユニット及び関連する構成を示す機能ブロック図である。 FIG. 2 is a functional block diagram illustrating an electronic control unit and related configurations according to an embodiment of the present disclosure.
　ＥＣＵ５０は、惰行制御実行手段の一例としての惰行制御実行部５１と、上昇量決定手段の一例としての上昇量決定部５２と、上昇量記憶手段の一例としての上昇量記憶部５３とを一部の機能要素として有する。これら各機能要素は、本実施形態では一体のハードウェアであるＥＣＵ５０に含まれるものとして説明するが、これらのいずれか一部を別体のハードウェアに設けることもできる。 The ECU 50 partially includes a coasting control execution unit 51 as an example of a coasting control execution unit, a rising amount determination unit 52 as an example of a rising amount determination unit, and a rising amount storage unit 53 as an example of a rising amount storage unit. As a functional element. In the present embodiment, these functional elements are described as being included in the ECU 50, which is an integral piece of hardware. However, any one of these functional elements may be provided in separate hardware.
　惰行制御実行部５１は、入力されるセンサ値に基づいて、所定の惰行制御開始条件を満たすか否かを判定する。惰行制御開始条件としては、例えば、アクセル開度が所定量以上低下した場合としてもよい。なお、惰行制御開始条件としては、これに限られず、種々の条件とすることができ、例えば、１以上のセンサ値がエンジン１０が駆動輪に対して正の仕事をしない運転状態を示す場合を条件としてもよい。 The coasting control execution unit 51 determines whether or not a predetermined coasting control start condition is satisfied based on the input sensor value. As the coasting control start condition, for example, the accelerator opening may be decreased by a predetermined amount or more. The coasting control start condition is not limited to this, and may be various conditions. For example, a case where one or more sensor values indicate an operating state in which the engine 10 does not perform positive work on the drive wheels. It is good also as conditions.
　惰行制御実行部５１は、惰行制御開始条件を満たすと判定した場合には、エンジン１０の回転数を所定の回転数（例えば、エンジン１０の通常（車両停止時）のアイドル回転数よりも低い回転数）に低下させる制御を行うとともに、油圧制御装置１８にクラッチ１１を断状態にさせるように制御する。 When the coasting control execution unit 51 determines that the coasting control start condition is satisfied, the rotational speed of the engine 10 is lower than a predetermined rotational speed (for example, a rotational speed lower than the normal idle speed of the engine 10 (when the vehicle is stopped)). And the hydraulic control device 18 is controlled to make the clutch 11 disengaged.
　惰行制御実行部５１は、入力されるセンサ値に基づいて、所定の惰行制御終了条件を満たすか否かを判定する。惰行制御終了条件としては、例えば、アクセル開度が所定量以上増加した場合としてもよい。なお、惰行制御終了条件としては、これに限られず、種々の条件とすることができ、例えば、１以上のセンサ値がエンジン１０が駆動輪に対して正の仕事をしない運転状態が解消されたことを示す場合を条件としてもよい。 The coasting control execution unit 51 determines whether or not a predetermined coasting control end condition is satisfied based on the input sensor value. As the coasting control end condition, for example, the accelerator opening may be increased by a predetermined amount or more. The coasting control end condition is not limited to this, and can be various conditions. For example, an operation state in which one or more sensor values do not cause the engine 10 to perform positive work on the drive wheels has been eliminated. This may be a condition.
　惰行制御実行部５１は、惰行制御終了条件を満たすと判定した場合には、惰行制御の終了処理、すなわち、エンジン１０の回転数を上昇量決定部５２が決定したエンジン回転数上昇量だけ上昇させる制御を行うとともに、エンジン１０が所定の回転数まで上昇した場合に、油圧制御装置１８にクラッチ１１を接状態にさせるように制御する処理を実行する。 When the coasting control execution unit 51 determines that the coasting control end condition is satisfied, the coasting control end process, that is, increases the engine speed by the engine speed increase amount determined by the increase amount determination unit 52. While performing control, when the engine 10 rises to a predetermined number of revolutions, a process of controlling the hydraulic control device 18 to bring the clutch 11 into the engaged state is executed.
　本実施形態では、惰行制御実行部５１は、惰行制御終了条件を満たすと判定した場合には、上昇量決定部５２にエンジン回転数上昇量を問い合わせ、上昇量決定部５２から取得したエンジン回転数上昇量に従ってエンジン１０の回転数を上昇させる制御（フィードフォワード制御）を行う。 In the present embodiment, when the coasting control execution unit 51 determines that the coasting control end condition is satisfied, the coasting control execution unit 51 inquires of the increase amount determination unit 52 about the engine rotation number increase amount and acquires the engine rotation number acquired from the increase amount determination unit 52. Control for increasing the rotational speed of the engine 10 according to the amount of increase (feed forward control) is performed.
　上昇量記憶部５３は、エンジン回転数とクラッチ１１の変速機１２側の回転数（変速機１２のインプットシャフトの回転数）との回転数差と、その回転数差である場合に、惰行制御の終了処理において上昇させるべきエンジン回転数（エンジン回転数上昇量という。）との関係を示すエンジン回転数上昇量マップ（エンジン回転数上昇量情報の一例）を記憶する。エンジン回転数上昇量は、例えば、エンジン１０に供給する燃料の増加量として表現してもよい。 The increase amount storage unit 53 performs coasting control when the rotational speed difference between the engine rotational speed and the rotational speed of the clutch 11 on the transmission 12 side (the rotational speed of the input shaft of the transmission 12) is the rotational speed difference. The engine speed increase map (an example of engine speed increase information) indicating the relationship with the engine speed (referred to as engine speed increase) that should be increased in the end process is stored. The engine speed increase amount may be expressed, for example, as an increase amount of fuel supplied to the engine 10.
　図３は、本開示の一実施形態に係る車両制御装置におけるエンジン回転数上昇量マップにおける回転数差とエンジン回転数上昇量との関係を示す図である。 FIG. 3 is a diagram illustrating a relationship between a rotational speed difference and an engine speed increase amount in an engine speed increase map in the vehicle control device according to an embodiment of the present disclosure.
　図３に示すように、エンジン回転数上昇量マップにおいては、エンジン回転数とクラッチ１１の変速機１２側の回転数との回転数差が大きくなるほど、エンジン回転数上昇量が多くなるような関係となっている。本実施形態においては、エンジン回転数上昇量は、図３中の破線で示す変速機１２の変速段にシフトダウンする際に上昇させるべきエンジン回転数の上昇量（シフトダウン時上昇量という）よりも小さくなっている。 As shown in FIG. 3, in the engine speed increase map, the engine speed increase increases as the difference between the engine speed and the speed of the clutch 11 on the transmission 12 side increases. It has become. In the present embodiment, the engine speed increase amount is based on the engine speed increase amount to be increased when shifting down to the gear stage of the transmission 12 indicated by the broken line in FIG. Is also getting smaller.
　図２の説明に戻り、上昇量決定部５２は、車速センサ２１からの車速に基づいて、変速機１２のインプットシャフトの回転数を特定する。具体的には、車速から変速機１２の現在の変速段のギア比を用いることにより、変速機１２のインプットシャフトの回転数を特定することができる。なお、変速機１２のインプットシャフトの回転数を検出するセンサを備えるようにして、そのセンサの出力値によりインプットシャフトの回転数を特定するようにしてもよい。 Returning to the description of FIG. 2, the lift amount determination unit 52 specifies the rotation speed of the input shaft of the transmission 12 based on the vehicle speed from the vehicle speed sensor 21. Specifically, the rotational speed of the input shaft of the transmission 12 can be specified by using the gear ratio of the current gear position of the transmission 12 from the vehicle speed. A sensor for detecting the rotational speed of the input shaft of the transmission 12 may be provided, and the rotational speed of the input shaft may be specified by the output value of the sensor.
　上昇量決定部５２は、エンジン回転数センサ２０からのエンジン回転数と、特定したインプットシャフトの回転数との回転数差を算出し、上昇量記憶部５３のエンジン回転数上昇量マップを参照して、エンジン回転数上昇量を決定する。本実施形態では、上昇量決定部５２は、惰行制御実行部５１から問い合わせを受けた場合（すなわち、惰行制御の終了処理の条件が合致した場合）における回転数差から、エンジン回転数上昇量を決定する。上昇量決定部５２は、決定したエンジン回転数上昇量を惰行制御実行部５１に通知する。 The increase amount determination unit 52 calculates the rotation speed difference between the engine rotation speed from the engine rotation speed sensor 20 and the identified rotation speed of the input shaft, and refers to the engine rotation speed increase map in the increase amount storage unit 53. To determine the engine speed increase. In the present embodiment, the increase amount determination unit 52 determines the engine rotation amount increase amount from the difference in rotation number when the inquiry is received from the coasting control execution unit 51 (that is, when the conditions of the coasting control end process are met). decide. The increase amount determination unit 52 notifies the coasting control execution unit 51 of the determined engine speed increase amount.
　次に、本開示の一実施形態に係る車両制御処理について説明する。 Next, a vehicle control process according to an embodiment of the present disclosure will be described.
　図４は、本開示の一実施形態に係る車両制御処理のフローチャートである。 FIG. 4 is a flowchart of a vehicle control process according to an embodiment of the present disclosure.
　この車両制御処理は、例えば、エンジン１０の始動（イグニッションスイッチのキースイッチＯＮ）と同時に開始される。 This vehicle control process is started, for example, at the same time as starting the engine 10 (ignition switch key switch ON).
　惰行制御実行部５１は、車両の状態が惰行制御開始条件に合致するか否かを判定する（Ｓ１０）。この結果、車両の状態が惰行制御開始条件に合致しない場合には、惰行制御実行部５１は、ステップＳ１０の処理を繰り返す（Ｓ１０：ＮＯ）。 The coasting control execution unit 51 determines whether or not the state of the vehicle matches the coasting control start condition (S10). As a result, when the state of the vehicle does not match the coasting control start condition, the coasting control execution unit 51 repeats the process of step S10 (S10: NO).
　一方、車両の状態が惰行制御開始条件に合致する場合（Ｓ１０：ＹＥＳ）には、惰行制御実行部５１は、惰行制御を開始する（Ｓ１１）。具体的には、惰行制御実行部５１は、エンジン１０の回転数を所定の回転数（例えば、エンジン１０のアイドル回転数よりも低い回転数）に低下させる制御を行うとともに、油圧制御装置１８にクラッチ１１を断状態にさせるように制御する。この結果、エンジン１０における燃料消費を適切に低減することができる。 On the other hand, when the state of the vehicle matches the coasting control start condition (S10: YES), the coasting control execution unit 51 starts coasting control (S11). Specifically, the coasting control execution unit 51 performs control to reduce the rotational speed of the engine 10 to a predetermined rotational speed (for example, a rotational speed lower than the idle rotational speed of the engine 10), and controls the hydraulic control device 18. Control is performed so that the clutch 11 is disengaged. As a result, fuel consumption in the engine 10 can be appropriately reduced.
　次いで、惰行制御実行部５１は、車両の状態が惰行制御終了条件に合致するか否かを判定する（Ｓ１２）。この結果、車両の状態が惰行制御終了条件に合致しない場合（Ｓ１２：ＮＯ）には、惰行制御実行部５１は、惰行制御の状態を維持し、ステップＳ１２の処理を繰り返す。 Next, the coasting control execution unit 51 determines whether or not the state of the vehicle matches the coasting control end condition (S12). As a result, when the state of the vehicle does not match the coasting control end condition (S12: NO), the coasting control execution unit 51 maintains the coasting control state and repeats the process of step S12.
　一方、車両の状態が惰行制御終了条件に合致する場合（Ｓ１２：ＹＥＳ）には、惰行制御実行部５１は、上昇量決定部５２にエンジン回転数上昇量を問い合わせ、問い合わせを受けた上昇量決定部５２が、エンジン回転数上昇量を決定し、惰行制御実行部５１にエンジン回転数上昇量を通知する（Ｓ１３）。 On the other hand, when the state of the vehicle matches the coasting control end condition (S12: YES), coasting control execution unit 51 inquires engine speed increase amount from engine amount determination unit 52 and determines the engine amount to be increased. The unit 52 determines the engine speed increase amount and notifies the coasting control execution unit 51 of the engine speed increase amount (S13).
　次いで、惰行制御実行部５１は、惰行制御終了処理を行う（Ｓ１４）。惰行制御終了処理においては、惰行制御実行部５１は、回転数決定部５２により決定されたエンジン回転数上昇量に従ってエンジン１０の回転数を上昇させ、エンジン回転数を上昇させた後、油圧制御装置１８にクラッチ１１を接状態にさせるように制御する。ここで、エンジン回転数上昇量は、シフトダウン時の上昇量よりも低いので、シフトダウン時の上昇量を用いた場合に比して、エンジン回転数が変速機１２のインプットシャフトの回転数をオーバーシュートしてしまうことを低減できる。また、惰行制御終了処理を開始する際に決定したエンジン回転数上昇量により制御するので、フィードバック制御のようにエンジン回転数が変速機１２のインプットシャフトの回転数をオーバーシュートしてしまうことを防止できるとともに、迅速に制御を行うことができる。 Next, the coasting control execution unit 51 performs coasting control end processing (S14). In the coasting control end process, the coasting control execution unit 51 increases the rotational speed of the engine 10 in accordance with the engine rotational speed increase amount determined by the rotational speed determination unit 52 and increases the engine rotational speed. 18 is controlled to bring the clutch 11 into the engaged state. Here, since the engine speed increase amount is lower than the increase amount at the time of downshifting, the engine speed is less than the speed of the input shaft of the transmission 12 as compared with the case of using the increase amount at the time of downshifting. Overshooting can be reduced. Further, since the control is performed based on the engine speed increase amount determined when starting the coasting control end process, the engine speed is prevented from overshooting the input shaft speed of the transmission 12 like feedback control. As well as being able to control quickly.
　なお、本発明は、上述の実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で、適宜変形して実施することが可能である。 It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately modified and implemented without departing from the spirit of the present invention.
　例えば、上記実施形態では、ＡＭＴを例に説明していたが、本発明はこれに限られず、自動でクラッチを断接することができれば、トランスミッションは、マニュアル式のトランスミッションであっても、他の方式の自動式トランスミッション（例えば、トルクコントローラ式トランスミッション）であってもよい。 For example, in the above-described embodiment, AMT has been described as an example. However, the present invention is not limited to this, and the transmission may be another type even if the transmission is a manual transmission as long as the clutch can be automatically connected and disconnected. The automatic transmission (for example, torque controller type transmission) may be used.
