モータジェネレータ４０は、電動機および発電機の機能を有する回転電機であり、ドライブシャフト１１を介して車輪１２に連結されている。   The motor generator 40 is a rotating electric machine having the functions of a motor and a generator, and is connected to the wheels 12 via the drive shaft 11.

バッテリ５０は、リチウムイオンバッテリ等の二次電池からなり、発電機３０、モータジェネレータ４０および図示しない電装品等に電力を供給する。また、バッテリ５０は、発電機３０およびモータジェネレータ４０が発電した電力を蓄電する。   The battery 50 is formed of a secondary battery such as a lithium ion battery, and supplies power to the generator 30, the motor generator 40, and electric components (not shown). Battery 50 stores the electric power generated by generator 30 and motor generator 40.

ＥＣＵ６０は、ＣＰＵ（Central Processing Unit）と、ＲＡＭ（Random Access Memory）と、ＲＯＭ（Read Only Memory）と、バックアップ用のデータなどを保存するフラッシュメモリと、入力ポートと、出力ポートとを備えたコンピュータユニットによって構成されている。   The ECU 60 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory for storing backup data and the like, an input port, and an output port.

切替スイッチ８１は、自動発電モードと手動発電モードとの切替操作を行うスイッチである。自動発電モードは、車両１０の電源がオンのときに、バッテリ５０の充電状態（ＳＯＣ）の低下等に応じて、自動的にエンジン２０を駆動し発電機３０により発電を行い、バッテリ５０に充電を行うモードである。手動発電モードは、充電スイッチ７０により充電の開始操作が行われたときにのみ、エンジン２０を駆動し発電機３０により発電を行い、バッテリ５０に充電を行うモードである。   The changeover switch 81 is a switch for performing a switching operation between the automatic power generation mode and the manual power generation mode. In the automatic power generation mode, when the power of the vehicle 10 is turned on, the engine 20 is automatically driven to generate electric power by the generator 30 in accordance with a decrease in the state of charge (SOC) of the battery 50 and the battery 50 is charged. Mode. The manual power generation mode is a mode in which the engine 20 is driven, the generator 30 generates power, and the battery 50 is charged only when a charging start operation is performed by the charging switch 70.

充電スイッチ７０はＥＣＵ６０に電気的に接続されており、ＥＣＵ６０は、充電スイッチ７０がオンであることを検出する。充電スイッチ７０がオンに操作された場合、ＥＣＵ６０は、車両１０の電源が入る前と後の何れであっても充電スイッチ７０がオンであることを検出する。   The charging switch 70 is electrically connected to the ECU 60, and the ECU 60 detects that the charging switch 70 is on. When the charging switch 70 is turned on, the ECU 60 detects that the charging switch 70 is on either before or after the power of the vehicle 10 is turned on.

また、ＥＣＵ６０は、エンジン２０および発電機３０によるバッテリ５０への充電量を調整する。ＥＣＵ６０は、本発明における充電制御部、検出部および充電量調整部を構成する。   ECU 60 adjusts the amount of charge of battery 50 by engine 20 and generator 30. The ECU 60 constitutes a charge control unit, a detection unit, and a charge amount adjustment unit in the present invention.

なお、操作パネル８０に設置された充電スイッチ７０に代えて、車両１０のリモコンキーと一体化した充電スイッチ７０Ａやスマートフォンのアプリケーションにより駆動する充電スイッチ７０Ｂがオンにされたことを、ＥＣＵ６０が検出するようにしてもよい。ＥＣＵ６０は、車両１０の電源が入る前と後の何れであっても充電スイッチ７０Ａや充電スイッチ７０Ｂがオンであることを検出する。   The ECU 60 detects that the charge switch 70A integrated with the remote control key of the vehicle 10 and the charge switch 70B driven by the application of the smartphone are turned on instead of the charge switch 70 provided on the operation panel 80. You may do so. The ECU 60 detects that the charging switch 70A or the charging switch 70B is on either before or after the power of the vehicle 10 is turned on.

以上のように構成された車両１０のＥＣＵ６０による動作について、図３に示すフローチャートを参照して説明する。   The operation of the vehicle 10 configured as above by the ECU 60 will be described with reference to the flowchart shown in FIG.

図３において、ＥＣＵ６０は、車両１０の電源がオフか否かを判別し（ステップＳ１）、電源がオフでない場合は今回の動作を終了し、電源がオフである場合はステップＳ２に進む。   In FIG. 3, the ECU 60 determines whether or not the power of the vehicle 10 is off (step S1). If the power is not off, the current operation ends, and if the power is off, the process proceeds to step S2.

ステップＳ２において、ＥＣＵ６０は、充電スイッチ７０がオンであるか否かを判別し、充電スイッチ７０がオンでない場合は今回の動作を終了し、充電スイッチ７０がオンである場合はステップＳ３に進む。   In step S2, the ECU 60 determines whether or not the charging switch 70 is on. If the charging switch 70 is not on, the current operation ends. If the charging switch 70 is on, the process proceeds to step S3.

ステップＳ３において、ＥＣＵ６０は、制御装置（エンジン２０および発電機３０の制御機能をいう）を起動し、エンジン２０を始動して発電機３０による発電を開始し、バッテリ５０を充電する。このステップＳ３では、ＥＣＵ６０は、エンジン２０および発電機３０によるバッテリ５０への充電量を調整する。ここで、充電量とは、例えば、充電電流、充電電圧またはバッテリ５０の目標ＳＯＣをいう。   In step S3, the ECU 60 activates the control device (refers to the control function of the engine 20 and the generator 30), starts the engine 20, starts power generation by the generator 30, and charges the battery 50. In step S3, the ECU 60 adjusts the amount of charge of the battery 50 by the engine 20 and the generator 30. Here, the charge amount refers to, for example, a charge current, a charge voltage, or a target SOC of the battery 50.

そして、ＥＣＵ６０は、所定の条件が成立したとき、バッテリ５０の充電を終了し、今回の動作を終了する。   Then, when the predetermined condition is satisfied, the ECU 60 ends the charging of the battery 50 and ends the current operation.

なお、ＥＣＵ６０とは別に、エンジン２０および発電機３０を制御する制御装置を車両１０に設け、この制御装置がステップ３の処理を行うようにしてもよい。   Note that a control device for controlling the engine 20 and the generator 30 may be provided in the vehicle 10 separately from the ECU 60, and the control device may perform the process of step 3.

また、ＥＣＵ６０は、バッテリ５０の充電中に、バッテリ５０の現時点の充電状態での走行可能距離、または満充電に要する残り時間等を、表示によりドライバに通知するようにしてもよい。また、ＥＣＵ６０は、バッテリ５０の充電中に、現時点での残燃料の量に基づく走行可能距離を表示によりドライバに通知するようにしてもよい。   Further, the ECU 60 may notify the driver of the travelable distance in the current charged state of the battery 50 or the remaining time required for full charging while the battery 50 is being charged. In addition, the ECU 60 may notify the driver of the travelable distance based on the current amount of remaining fuel to the driver while the battery 50 is being charged.

以上のように、本実施例において、ＥＣＵ６０は、車両１０の電源が入る前であって充電スイッチ７０がオンとなった場合に、エンジン２０を駆動してバッテリ５０に充電を行う。   As described above, in the present embodiment, the ECU 60 drives the engine 20 to charge the battery 50 before the power of the vehicle 10 is turned on and the charging switch 70 is turned on.

これにより、車両１０の電源が入る前であっても、充電スイッチ７０がオンとなった場合に、エンジン２０を駆動してバッテリ５０に充電が行われるので、ドライバの意図したタイミングで、バッテリ５０の充電のためのエンジン２０の運転をすることができる。   As a result, even before the power of the vehicle 10 is turned on, when the charging switch 70 is turned on, the engine 20 is driven to charge the battery 50, and the battery 50 is charged at the timing intended by the driver. Of the engine 20 for charging the battery.

これにより、ドライバが休憩のために車両１０を離れている間でも、車両１０の停車中にバッテリ５０を充電することができる。   This allows the battery 50 to be charged while the vehicle 10 is stopped, even while the driver is leaving the vehicle 10 for a break.

また、仮にバッテリ５０の充電を走行中に自動的に行うようにした場合は、充電完了までに時間を要してしまい、その分の余分な燃料を消費してしまうが、車両１０の停車中にバッテリ５０を充電することができるため、充電時間を短縮でき、燃料消費量を削減できる。   If the battery 50 is automatically charged during traveling, it takes a long time to complete charging and consumes extra fuel for that time. Since the battery 50 can be charged in a short time, the charging time can be reduced, and the fuel consumption can be reduced.

また、本実施例において、ＥＣＵ６０は、車両１０の電源が入る前と後の何れであっても充電スイッチ７０がオンであることを検出する。   In the present embodiment, the ECU 60 detects that the charging switch 70 is on either before or after the power of the vehicle 10 is turned on.

これにより、車両１０の電源が入る前であってもドライバの意図したタイミングでバッテリ５０を充電することができ、車両１０の電源が入った後は、自動発電モードで自動的にバッテリ５０を充電することができる。   This allows the battery 50 to be charged at a timing intended by the driver even before the vehicle 10 is turned on, and automatically charges the battery 50 in the automatic power generation mode after the vehicle 10 is turned on. can do.

また、本実施例において、ＥＣＵ６０は、エンジン２０および発電機３０によるバッテリ５０への充電量を調整する。   In the present embodiment, the ECU 60 adjusts the amount of charge of the battery 50 by the engine 20 and the generator 30.

本発明の実施例を開示したが、当業者によっては本発明の範囲を逸脱することなく変更が加えられうることは明白である。例えば、発電機３０とエンジンの始動装置であるスタータとを別個に設けることとしたが、発電機３０を、発電機とスタータとの機能を共に有するスタータジェネレータとしてもよい。すべてのこのような修正および等価物が次の請求項に含まれることが意図されている。   While embodiments of the present invention have been disclosed, it will be apparent that modifications may be made by those skilled in the art without departing from the scope of the invention. For example, although the generator 30 and the starter which is a starting device of the engine are separately provided, the generator 30 may be a starter generator having both functions of the generator and the starter. All such modifications and equivalents are intended to be included in the following claims.
