従来より、内燃機関および電動機を利用して走行するハイブリッド車両が実用に供されている。ハイブリッド車両には、回転電機や蓄電装置が搭載される。蓄電装置は、内燃機関によって駆動される回転電機の発電電力で充電されることができる。   Conventionally, a hybrid vehicle that travels using an internal combustion engine and an electric motor has been put to practical use. A hybrid vehicle is equipped with a rotating electric machine and a power storage device. The power storage device can be charged with power generated by a rotating electrical machine driven by an internal combustion engine.

近年、蓄電装置の充電は、家屋などに設けられた電源に充電ケーブルのプラグを挿入して行なわれることもある。また、蓄電装置の電力が家屋に放電されることもある(たとえば特開2007−236023号公報参照)。このように充電ケーブルを介して家屋との間で電力伝送が行なわれるハイブリッド車両は、「プラグインハイブリッド車両」とも呼ばれる(たとえば特開2013−51772号公報参照)。   In recent years, charging of a power storage device is sometimes performed by inserting a plug of a charging cable into a power source provided in a house or the like. In addition, the power of the power storage device may be discharged to the house (see, for example, Japanese Patent Application Laid-Open No. 2007-236023). A hybrid vehicle in which power is transmitted to and from the house through the charging cable in this way is also referred to as a “plug-in hybrid vehicle” (see, for example, JP2013-51772A).

特開2007−236023号公報や特開2013−51772号公報は、ハイブリッド車両に搭載された回転電機の発電電力または蓄電装置の電力をハイブリッド車両の外部に供給すること(以下、「外部給電」という場合もある)を提案する。   Japanese Patent Application Laid-Open Nos. 2007-236023 and 2013-51772 supply electric power generated by a rotating electrical machine or power storage device mounted on a hybrid vehicle to the outside of the hybrid vehicle (hereinafter referred to as “external power supply”). Proposal).

蓄電装置から取り出すことができる電力の大きさは、蓄電装置の温度によって変化する。たとえば、蓄電装置の温度が低すぎると、蓄電装置から電力を取り出すことができなくなる。一方、蓄電装置の温度が高すぎると、たとえば蓄電装置の使用による劣化がはやまる可能性がある。そこで、蓄電装置の温度が低すぎる場合や高すぎる場合、蓄電装置から取り出すことができる電力の大きさが制限されることがある。しかし、蓄電装置から取り出すことができる電力の大きさが制限されると、外部給電が円滑に行なわれないおそれがある。そのため、蓄電装置の電力により外部給電を行なう際、蓄電装置の温度を考慮することが好ましい。   The amount of power that can be extracted from the power storage device varies depending on the temperature of the power storage device. For example, if the temperature of the power storage device is too low, electric power cannot be extracted from the power storage device. On the other hand, if the temperature of the power storage device is too high, deterioration due to use of the power storage device, for example, may stop. Thus, when the temperature of the power storage device is too low or too high, the amount of power that can be taken out from the power storage device may be limited. However, when the amount of power that can be taken out from the power storage device is limited, external power feeding may not be performed smoothly. Therefore, it is preferable to consider the temperature of the power storage device when external power feeding is performed using the power of the power storage device.

本発明の目的は、蓄電装置の温度を考慮しつつ外部給電を行なうことを可能にする、ハイブリッド車両の制御装置を提供することである。   An object of the present invention is to provide a control device for a hybrid vehicle that enables external power feeding while considering the temperature of the power storage device.

本発明は、一局面において、内燃機関と回転電機と蓄電装置とが搭載され外部給電が可能なハイブリッド車両に用いられる制御装置である。制御装置は、蓄電装置の温度に関連する情報を取得する温度情報取得部と、蓄電装置の温度が所定範囲外の場合、蓄電装置を充電せずに、内燃機関により回転電機を駆動させて回転電機の発電電力をハイブリッド車両の外部へ供給するようにハイブリッド車両を制御し、蓄電装置の温度が所定範囲内の場合、蓄電装置の電力をハイブリッド車両の外部へ供給するようにハイブリッド車両を制御する制御部とを備える。   In one aspect, the present invention is a control device used in a hybrid vehicle on which an internal combustion engine, a rotating electrical machine, and a power storage device are mounted and capable of external power feeding. The control device includes a temperature information acquisition unit that acquires information related to the temperature of the power storage device, and when the temperature of the power storage device is out of a predetermined range, the rotating electrical machine is driven by the internal combustion engine to rotate without charging the power storage device. The hybrid vehicle is controlled so that the electric power generated by the electric machine is supplied to the outside of the hybrid vehicle. When the temperature of the power storage device is within a predetermined range, the hybrid vehicle is controlled so that the power of the power storage device is supplied to the outside of the hybrid vehicle. And a control unit.

このようにすれば、たとえば、広い温度範囲において蓄電装置の特性に起因する制限を受けることなく、ハイブリッド車両の外部に電力を供給することが可能になる。   In this way, for example, electric power can be supplied to the outside of the hybrid vehicle without being restricted due to the characteristics of the power storage device in a wide temperature range.

好ましくは、所定範囲の上限温度は、上限温度より高い温度において蓄電装置が劣化するまたは蓄電装置の出力が制限される温度であり、所定範囲の下限温度は、下限温度より低い温度において蓄電装置の出力が制限される温度である。   Preferably, the upper limit temperature of the predetermined range is a temperature at which the power storage device deteriorates or the output of the power storage device is restricted at a temperature higher than the upper limit temperature, and the lower limit temperature of the predetermined range is a temperature lower than the lower limit temperature. This is the temperature at which the output is limited.

好ましくは、蓄電装置の温度に関連する情報は、蓄電装置の外部の気温である。
好ましくは、ハイブリッド車両には空調装置がさらに搭載され、制御装置は、蓄電装置の温度が所定範囲の下限温度よりも低い場合、空調装置を制御する。
Preferably, the information related to the temperature of the power storage device is the temperature outside the power storage device.
Preferably, the hybrid vehicle is further equipped with an air conditioner, and the control device controls the air conditioner when the temperature of the power storage device is lower than a lower limit temperature within a predetermined range.

本発明によると、蓄電装置の温度を考慮しつつ外部給電を行なうことが可能になる。   According to the present invention, external power feeding can be performed in consideration of the temperature of the power storage device.

In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

図1は、実施の形態によるハイブリッド車両の制御装置が制御するハイブリッド車両100(以下、単に「車両100」という)の全体ブロック図である。図1を参照して、車両100は、蓄電装置110と、システムメインリレー115(SMR115)と、PCU(Power Control Unit)120と、モータジェネレータMG1,MG2と、動力伝達ギヤ140と、駆動輪150と、内燃機関であるエンジン160と、制御装置であるECU(Electronic Control Unit)300と、充電リレー210(CHR210)と、電力変換装置200と、温度センサ800と、空調装置900とを備える。PCU120は、コンバータ121と、インバータ122,123と、コンデンサC1,C2とを含む。   FIG. 1 is an overall block diagram of a hybrid vehicle 100 (hereinafter simply referred to as “vehicle 100”) controlled by a hybrid vehicle control apparatus according to an embodiment. Referring to FIG. 1, vehicle 100 includes a power storage device 110, a system main relay 115 (SMR 115), a PCU (Power Control Unit) 120, motor generators MG1 and MG2, a power transmission gear 140, and drive wheels 150. And an engine 160 that is an internal combustion engine, an ECU (Electronic Control Unit) 300 that is a control device, a charging relay 210 (CHR 210), a power converter 200, a temperature sensor 800, and an air conditioner 900. PCU 120 includes a converter 121, inverters 122 and 123, and capacitors C1 and C2.

蓄電装置110は、充放電可能に構成された電力貯蔵要素である。蓄電装置110は、たとえば、リチウムイオン電池、ニッケル水素電池または鉛蓄電池などの二次電池、あるいは電気二重層キャパシタなどの蓄電素子を含んで構成される。蓄電装置110は、電力線PL1,NL1を通してPCU120に接続される。蓄電装置110の電圧VBおよび電流IBは、センサ(図示しない)によって測定され、その情報は、ECU300へ送られる。蓄電装置110に対して、電力線PL1,NL1と電力線PL2,NL2とが並列に設けられる。SMR115およびCHR210がオン状態のとき、電力線PL1,NL1と電力線PL2,NL2は、通電して同電位になる。電力線PL1,NL1は、蓄電装置110とコンバータ121を接続するための電力線である。電力線PL2,NL2は、蓄電装置110と電力変換装置200とを接続するための電力線である。蓄電装置110は、電力線PL1,NL1および電力線PL2,NL2に対して放電し、またはそれらの電力線から充電されることができる。   The power storage device 110 is a power storage element configured to be chargeable / dischargeable. The power storage device 110 includes, for example, a secondary battery such as a lithium ion battery, a nickel metal hydride battery, or a lead storage battery, or a power storage element such as an electric double layer capacitor. Power storage device 110 is connected to PCU 120 through power lines PL1 and NL1. Voltage VB and current IB of power storage device 110 are measured by a sensor (not shown), and the information is sent to ECU 300. For power storage device 110, power lines PL1, NL1 and power lines PL2, NL2 are provided in parallel. When SMR 115 and CHR 210 are on, power lines PL1, NL1 and power lines PL2, NL2 are energized to have the same potential. Power lines PL <b> 1 and NL <b> 1 are power lines for connecting power storage device 110 and converter 121. Power lines PL <b> 2 and NL <b> 2 are power lines for connecting power storage device 110 and power conversion device 200. Power storage device 110 can be discharged to or charged from power lines PL1, NL1 and PL2, NL2.

まず、蓄電装置110から電力線PL1,NL1側の構成について説明する。システムメインリレー115(SMR115)は、蓄電装置110と電力線PL1,NL1との間に設けられる。SMR115は、ECU300からの制御信号SE1に基づいて動作する。SMR115は、蓄電装置110とPCU120とを電気的に接続または遮断する。   First, the configuration on the power line PL1, NL1 side from power storage device 110 will be described. System main relay 115 (SMR 115) is provided between power storage device 110 and power lines PL1, NL1. The SMR 115 operates based on a control signal SE1 from the ECU 300. SMR 115 electrically connects or disconnects power storage device 110 and PCU 120.

PCU120は、コンデンサC1と、コンバータ121と、コンデンサC2と、インバータ122,123とを含む。   PCU 120 includes a capacitor C1, a converter 121, a capacitor C2, and inverters 122 and 123.

コンバータ121は、ECU300からの制御信号PWCに基づいて動作する。コンバータ121は、電圧変換を行なう。コンバータ121には、平滑化などのためのコンデンサC1,C2が接続される。   Converter 121 operates based on control signal PWC from ECU 300. Converter 121 performs voltage conversion. Capacitors C1 and C2 for smoothing and the like are connected to the converter 121.

インバータ122,123は、コンバータ121に対して並列に接続される。インバータ122,123は、ECU300からの制御信号PWI1,PWI2にそれぞれ基づいて動作する。インバータ122,123は、コンバータ121から供給される直流電力を交流電力に変換し、モータジェネレータMG1,MG2にそれぞれ供給する。また、インバータ122,123は、モータジェネレータMG1,MG2の発電電力(交流電力)を直流電力に変換し、コンバータ121に供給することもできる。   Inverters 122 and 123 are connected in parallel to converter 121. Inverters 122 and 123 operate based on control signals PWI1 and PWI2 from ECU 300, respectively. Inverters 122 and 123 convert DC power supplied from converter 121 into AC power and supply the AC power to motor generators MG1 and MG2, respectively. Inverters 122 and 123 can also convert electric power generated by motor generators MG 1 and MG 2 (AC power) into DC power and supply it to converter 121.

モータジェネレータMG1,MG2は交流回転電機である。モータジェネレータMG1,MG2の出力トルクは、動力伝達ギヤ140を介して駆動輪150に伝達される。動力伝達ギヤ140は、減速機や動力分割機構を含む。車両100の回生制動動作時には、モータジェネレータMG1,MG2は、駆動輪150の回転力によって発電することができる。モータジェネレータMG1,MG2は、動力伝達ギヤ140を介してエンジン160とも結合される。モータジェネレータMG1,MG2およびエンジン160は、ECU300の制御のもと、協調的に動作する。これにより、要求に応じた車両駆動力を発生させることができる。モータジェネレータMG1,MG2は、車両100の回生制動動作時だけでなく、エンジン160の回転によって発電することもできる。   Motor generators MG1 and MG2 are AC rotating electric machines. Output torque of motor generators MG1 and MG2 is transmitted to drive wheel 150 via power transmission gear 140. The power transmission gear 140 includes a speed reducer and a power split mechanism. During regenerative braking operation of vehicle 100, motor generators MG1 and MG2 can generate electric power by the rotational force of drive wheels 150. Motor generators MG 1 and MG 2 are also coupled to engine 160 through power transmission gear 140. Motor generators MG1 and MG2 and engine 160 operate cooperatively under the control of ECU 300. Thereby, the vehicle driving force according to a request | requirement can be generated. Motor generators MG 1 and MG 2 can generate power not only during regenerative braking operation of vehicle 100 but also by rotation of engine 160.

以上の構成において、ECU300は、エンジン160によりモータジェネレータMG1,MG2を駆動させて、モータジェネレータMG1,MG2の発電電力を電力線PL1,NL1に供給するように、車両100を制御することができる。   In the above configuration, ECU 300 can control vehicle 100 such that engine generator MG1 and MG2 are driven by engine 160 and the generated power of motor generators MG1 and MG2 is supplied to power lines PL1 and NL1.

次に、蓄電装置110から電力線PL2,NL2側の構成について説明する。CHR210は、蓄電装置110と電力線PL2,NL2との間に設けられる。CHR210は、ECU300からの制御信号SE2に基づいて動作する。CHR210は、蓄電装置110と電力変換装置200とを電気的に接続または遮断する。   Next, the configuration on the power line PL2, NL2 side from the power storage device 110 will be described. CHR 210 is provided between power storage device 110 and power lines PL2 and NL2. CHR 210 operates based on control signal SE2 from ECU 300. CHR 210 electrically connects or disconnects power storage device 110 and power conversion device 200.

電力変換装置200は、電力線ACL1,ACL2を介して、インレット220に接続される。電力変換装置200は、ECU300からの制御信号PWDによって制御される。電力変換装置200は、インレット220からの電力(基本的に交流電力)を、直流電力に変換し、電力線PL2,NL2へ供給する。また、電力変換装置200は、電力線PL2,NL2から直流電力を取り込んで交流電力に変換し、電力線ACL1,ACL2に供給することもできる。電力変換装置200は、充電および給電の双方向の電力変換が可能な1つの装置であってもよいし、充電用の装置および給電用の装置を個別の装置として含むものであってもよい。   Power conversion device 200 is connected to inlet 220 through power lines ACL1 and ACL2. Power conversion device 200 is controlled by a control signal PWD from ECU 300. Power conversion device 200 converts power (basically AC power) from inlet 220 into DC power and supplies it to power lines PL2 and NL2. In addition, power conversion device 200 can take DC power from power lines PL2 and NL2, convert it to AC power, and supply the AC power to ACL1 and ACL2. The power conversion device 200 may be a single device capable of bidirectional power conversion between charging and feeding, or may include a charging device and a feeding device as separate devices.

図1に示す例では、インレット220に、充電ケーブル400の充電コネクタ410が接続される。これにより、車両100の外部にある外部電源500からの電力が、インレット220に与えられる。なお、充電ケーブル400は、充電コネクタ410以外に、外部電源500のコンセント510に接続するためのプラグ420と、充電コネクタ410およびプラグ420とを接続する電力線440とを含む。電力線440には、外部電源500からの電力の供給および遮断を切換えるための充電回路遮断装置(CCID:Charging Circuit Interrupt Device)430が介挿される。   In the example shown in FIG. 1, charging connector 410 of charging cable 400 is connected to inlet 220. As a result, power from the external power source 500 outside the vehicle 100 is supplied to the inlet 220. In addition to charging connector 410, charging cable 400 includes a plug 420 for connecting to outlet 510 of external power supply 500, and a power line 440 for connecting charging connector 410 and plug 420. Charging circuit interrupt device (CCID) 430 for switching between supply and interruption of power from external power supply 500 is inserted in power line 440.

以上の構成において、ECU300は、電力線PL2,NL2の電力を、車両100の外部に供給するように、車両100を制御することができる。   In the above configuration, ECU 300 can control vehicle 100 so as to supply the power of power lines PL <b> 2 and NL <b> 2 to the outside of vehicle 100.

ECU300は、CPU(Central Processing Unit)、記憶装置および入出力バッファ(いずれも図示しない)を含む。ECU300は、各センサなどからの信号の入力や各機器への制御信号の出力を行なうとともに、蓄電装置110および車両100の各機器の制御を行なう。なお、これらの制御、専用のハードウェア(電子回路など)によって実現されることができ、ソフトウェアによって実現されることもできる。ECU300は、たとえば、蓄電装置110からの電圧VBおよび電流IBの検出値に基づいて、蓄電装置110の残存容量SOC(State of Charge)を演算する。また、ECU300は、充電ケーブル400の接続状態を示すプロキシメトリディテクション信号PISWを充電コネクタ410から受ける。さらに、ECU300は、充電ケーブル400のCCID430からコントロールパイロット信号CPLTを受ける。ECU300は、これらの信号に基づいて充電動作を実行する。なお、接続状態を示す信号PISWやパイロット信号CPLTは、たとえば米国のSAE(Society of Automotive Engineers)や日本電動車両協会などにおいて規格化されている。   ECU 300 includes a CPU (Central Processing Unit), a storage device, and an input / output buffer (all not shown). ECU 300 inputs signals from each sensor and the like and outputs control signals to each device, and controls each device of power storage device 110 and vehicle 100. Note that these controls can be realized by dedicated hardware (such as an electronic circuit), and can also be realized by software. ECU 300 calculates a remaining capacity SOC (State of Charge) of power storage device 110 based on, for example, detected values of voltage VB and current IB from power storage device 110. ECU 300 also receives from proxy connector 410 proxy measurement signal PISW indicating the connection state of charging cable 400. Further, ECU 300 receives control pilot signal CPLT from CCID 430 of charging cable 400. ECU 300 performs a charging operation based on these signals. The signal PISW indicating the connection state and the pilot signal CPLT are standardized by, for example, SAE (Society of Automotive Engineers) in the United States and the Japan Electric Vehicle Association.

温度センサ800は、車両100の温度を測定(または検出)する。具体的に、温度センサ800は、蓄電装置110の温度、または蓄電装置110の周囲の温度(以下、「外気温」という場合もある)を測定する。たとえば、蓄電装置110が車室や車室に連通するトランクルームなどに配置されている場合、温度センサ800は、車室の温度を測定するものであってもよい。温度センサ800の測定値は、ECU300に送られる。これにより、ECU300は、蓄電装置110の温度に関連する情報を取得することができる。   The temperature sensor 800 measures (or detects) the temperature of the vehicle 100. Specifically, temperature sensor 800 measures the temperature of power storage device 110 or the temperature around power storage device 110 (hereinafter also referred to as “outside air temperature”). For example, when power storage device 110 is disposed in a passenger compartment or a trunk room communicating with the passenger compartment, temperature sensor 800 may measure the temperature of the passenger compartment. The measured value of the temperature sensor 800 is sent to the ECU 300. Thereby, ECU 300 can acquire information related to the temperature of power storage device 110.

空調装置900は、車両100の温度を調節する。空調装置900は、たとえばエンジン160の駆動によるモータジェネレータMG1の発電電力または蓄電装置110の電力を利用して動作する。空調装置900は、ECU300によって制御される。これにより、ECU300は、車両100の温度を調節することができる。   The air conditioner 900 adjusts the temperature of the vehicle 100. Air conditioner 900 operates using, for example, power generated by motor generator MG1 driven by engine 160 or power stored in power storage device 110. The air conditioner 900 is controlled by the ECU 300. Thereby, ECU 300 can adjust the temperature of vehicle 100.

以上で図1を参照して説明したように、ECU300の制御によって、蓄電装置110とエンジン160とを搭載した車両100は、(1)蓄電装置110の電力のみを利用して外部給電を行なうことができる(蓄電装置のみによる外部給電)。また、車両100は、(2)エンジン160の駆動によるモータジェネレータMG1の発電電力のみを利用することもできる(エンジンのみによる外部給電)。さらに、車両100は、(3)蓄電装置110の電力とモータジェネレータMG1,MG2の発電電力とを組み合わせた電力を利用することもできる(蓄電装置およびエンジンによる外部給電)。   As described above with reference to FIG. 1, vehicle 100 equipped with power storage device 110 and engine 160 performs (1) external power feeding using only the power of power storage device 110 under the control of ECU 300. (External power supply using only the power storage device). Vehicle 100 can also use only (2) the power generated by motor generator MG1 driven by engine 160 (external power feeding only by the engine). Furthermore, vehicle 100 can also use (3) electric power obtained by combining electric power of power storage device 110 and electric power generated by motor generators MG1 and MG2 (external power feeding by the power storage device and the engine).

(1)蓄電装置のみによる外部給電の場合、コンバータ121は、電力線PL1,NL1への電力の供給を行なわない。一方、電力変換装置200は、電力線PL2,NL2からの電力を取り込んで変換し、電力線ACL1,ALC2へ供給する。その結果、蓄電装置110は電力線PL2,NL2に放電する。   (1) In the case of external power feeding only by the power storage device, converter 121 does not supply power to power lines PL1, NL1. On the other hand, power conversion device 200 takes in power from power lines PL2 and NL2, converts it, and supplies it to power lines ACL1 and ALC2. As a result, power storage device 110 discharges to power lines PL2 and NL2.

一方、(2)エンジンのみによる外部給電の場合、コンバータ121は、電力線PL1,NL1へ電力を供給する。電力変換装置200は、電力線PL2,NL2から電力を取り込んで変換し、電力線ACL1,ALC2へ供給する。このとき、コンバータ121が電力線PL1,NL1へ供給する電力と、電力変換装置200が電力線PL2,NL2から取り込む電力とが等しくなるように、コンバータ121と電力変換装置200とがECU300によって制御される。その結果、蓄電装置110は、電力線PL2,NL2に放電しない。さらに、蓄電装置110は、電力線PL1,NL1から充電されることもない。これにより、蓄電装置110の充放電に伴う電力損失が生じるのを防ぐことができる。このような制御においても、蓄電装置110がわずかに充放電されることもあるが、実施の形態において、そのような微視的な充放電は、蓄電装置110の充放電に含まれないと理解されるべきである。すなわち、ECU300は、蓄電装置110を充電せずに、エンジン160によりモータジェネレータMG1を駆動させてモータジェネレータMG1の発電電力を車両100の外部へ供給するように、車両100を制御する。   On the other hand, (2) In the case of external power feeding only by the engine, converter 121 supplies power to power lines PL1, NL1. Power conversion device 200 takes in power from power lines PL2 and NL2, converts it, and supplies it to power lines ACL1 and ALC2. At this time, the converter 121 and the power conversion device 200 are controlled by the ECU 300 so that the power supplied by the converter 121 to the power lines PL1 and NL1 is equal to the power taken by the power conversion device 200 from the power lines PL2 and NL2. As a result, power storage device 110 does not discharge to power lines PL2 and NL2. Furthermore, power storage device 110 is not charged from power lines PL1 and NL1. Thereby, it is possible to prevent a power loss due to charging / discharging of power storage device 110 from occurring. Even in such control, the power storage device 110 may be slightly charged / discharged, but in the embodiment, it is understood that such microscopic charge / discharge is not included in the charge / discharge of the power storage device 110. It should be. In other words, ECU 300 controls vehicle 100 such that motor generator MG1 is driven by engine 160 and electric power generated by motor generator MG1 is supplied to the outside of vehicle 100 without charging power storage device 110.

また、(3)蓄電装置およびエンジンによる外部給電の場合、コンバータ121は、電力線PL1,NL1へ電力を供給する。電力変換装置200は、電力線PL2,NL2から電力を取り込んで変換し、電力線ACL1,ALC2へ供給する。このとき、電力変換装置200が電力線PL2,NL2から取り込む電力は、コンバータ121が電力線PL1,NL1へ供給する電力よりも大きい。その結果、蓄電装置110は、電力線PL2,NL2に放電する。   (3) In the case of external power feeding by the power storage device and the engine, converter 121 supplies power to power lines PL1, NL1. Power conversion device 200 takes in power from power lines PL2 and NL2, converts it, and supplies it to power lines ACL1 and ALC2. At this time, the power that power conversion device 200 captures from power lines PL2 and NL2 is greater than the power that converter 121 supplies to power lines PL1 and NL1. As a result, power storage device 110 discharges to power lines PL2 and NL2.

なお、実施の形態によるハイブリッド車両の制御装置が制御するハイブリッド車両は、ハイブリッド車両のシステムに依存しない。すなわち、蓄電装置のみによる外部給電、エンジンのみによる外部給電、蓄電装置およびエンジンによる外部給電ができるタイプのハイブリッド車両であれば、実施の形態によるハイブリッド車両の制御装置による制御を適用することができる。   The hybrid vehicle controlled by the hybrid vehicle control device according to the embodiment does not depend on the hybrid vehicle system. That is, control by the hybrid vehicle control device according to the embodiment can be applied to any type of hybrid vehicle that can perform external power supply using only the power storage device, external power supply using only the engine, and external power supply using the power storage device and the engine.

図2は、外部給電の際の、車両100と車両外部の電気機器との接続を説明するための図である。図2に示すように、車両100が電気機器700に電力を供給する際、給電専用のコネクタ(給電コネクタ)600が用いられる。給電コネクタ600には、外部の電気機器700の電源プラグ710を接続することができる出力部610が設けられる。給電コネクタ600がインレット220に接続されると、車両100側の電力線ACL1,ACL2と出力部610とが電力伝達部620を介して電気的に接続される。   FIG. 2 is a diagram for explaining a connection between the vehicle 100 and an electric device outside the vehicle at the time of external power feeding. As shown in FIG. 2, when the vehicle 100 supplies electric power to the electric device 700, a dedicated power supply connector (power supply connector) 600 is used. The power supply connector 600 is provided with an output unit 610 to which a power plug 710 of an external electric device 700 can be connected. When power feeding connector 600 is connected to inlet 220, power lines ACL1 and ACL2 on vehicle 100 side and output unit 610 are electrically connected via power transmission unit 620.

図1および図2を参照して、ECU300は、インレット220に給電コネクタ600が接続されたことを認識(または検出)するように構成されている。この認識は、たとえば、給電コネクタ600のインレット220への接続に応じて動作するスイッチ(図示しない)などを利用して行なわれる。さらに、ECU300は、給電コネクタ600を介して、車両100の外部と通信するように構成されてもよい。通信において、上述の信号PISWのような信号が利用されてもよい。あるいは、通信において、通信電力線通信(PLC)が利用されてもよい。たとえば、インレット220に給電コネクタ600が接続されると、車両100は外部給電可能な動作状態(外部給電モード)に設定される。また、たとえば、インレット220から給電コネクタ600が外されると、車両100は外部給電モードを終了する。   Referring to FIGS. 1 and 2, ECU 300 is configured to recognize (or detect) that power feeding connector 600 is connected to inlet 220. This recognition is performed using, for example, a switch (not shown) that operates in response to the connection of the power feeding connector 600 to the inlet 220. Further, ECU 300 may be configured to communicate with the outside of vehicle 100 via power supply connector 600. In communication, a signal such as the above-described signal PISW may be used. Alternatively, communication power line communication (PLC) may be used in communication. For example, when power supply connector 600 is connected to inlet 220, vehicle 100 is set to an operation state (external power supply mode) in which external power supply is possible. For example, when power supply connector 600 is disconnected from inlet 220, vehicle 100 ends the external power supply mode.

車両100が外部給電モードに設定されると、ECU300は、CHR210をオン状態にするとともに、電力変換装置200を動作させ、車両100から電気機器700へ電力を供給する。これにより、外部給電が行なわれる。外部給電が行なわれている間、蓄電装置110からの電力、エンジン160の駆動によるモータジェネレータMG1の発電電力、またはそれらを組み合わせた電力が、電力変換装置200へ送られる。電力変換装置200は、そのような電力を受けて、電気機器700の適切な動作に要求される電圧および電流(電力)に変換して出力する。電気機器700への電力供給に要求される電圧及び電流(要求電力)に関連する情報は、たとえば、ECU300が、ECU300と車両100の外部との通信を利用して取得する。   When vehicle 100 is set to the external power supply mode, ECU 300 turns CHR 210 on and operates power conversion device 200 to supply electric power from vehicle 100 to electric device 700. Thereby, external power feeding is performed. While external power feeding is being performed, the power from power storage device 110, the power generated by motor generator MG1 driven by engine 160, or a combination of these is sent to power conversion device 200. The power conversion device 200 receives such power, converts it into voltage and current (power) required for proper operation of the electric device 700, and outputs the voltage and current (power). The information related to the voltage and current (required power) required for power supply to the electric device 700 is acquired by the ECU 300 using communication between the ECU 300 and the outside of the vehicle 100, for example.

図3は、図1のECU300の詳細の一例を説明するための図である。図3を参照して、ECU300は、温度情報取得部310と、判断部320と、制御部330と、その他の回路340とを備える。   FIG. 3 is a diagram for explaining an example of the details of ECU 300 in FIG. 1. Referring to FIG. 3, ECU 300 includes a temperature information acquisition unit 310, a determination unit 320, a control unit 330, and other circuits 340.

図1〜図3を参照して、温度情報取得部310は、温度センサ800から送られる温度情報を取得する。取得された温度情報は、判断部320に送られる。   With reference to FIGS. 1 to 3, temperature information acquisition section 310 acquires temperature information sent from temperature sensor 800. The acquired temperature information is sent to the determination unit 320.

判断部320は、温度情報取得部310から送られる温度情報を受けて、蓄電装置110の温度が所定範囲を超えるか否かを判断する。温度情報が蓄電装置110の周囲の気温(外気温)である場合、判断部320は、外気温を蓄電装置110の温度と推定する。蓄電装置の温度は、その周囲の温度(外気温)に近い温度であることが、発明者らの実験などによって分かっているためである。判断部320の判断結果は、制御部330に送られる。   Determination unit 320 receives temperature information sent from temperature information acquisition unit 310 and determines whether the temperature of power storage device 110 exceeds a predetermined range. When the temperature information is the ambient temperature (outside temperature) around power storage device 110, determination unit 320 estimates the outside temperature as the temperature of power storage device 110. This is because the temperature of the power storage device is known to be close to the ambient temperature (outside air temperature) by experiments of the inventors. The determination result of the determination unit 320 is sent to the control unit 330.

制御部330は、判断部320の判断結果を受けて、車両100から電気機器700への電力供給を制御する。その際、制御部330は、蓄電装置110の温度を考慮する。蓄電装置110の温度が考慮される理由については、後に図4を参照して説明する。   Control unit 330 receives the determination result of determination unit 320 and controls power supply from vehicle 100 to electric device 700. At that time, the controller 330 considers the temperature of the power storage device 110. The reason why the temperature of the power storage device 110 is taken into account will be described later with reference to FIG.

蓄電装置110の温度が所定範囲外の場合、制御部330は、(2)エンジン160のみによる外部給電、を優先させる。エンジンのみでは供給電力が不足する場合、制御部330は、(3)蓄電装置110およびエンジン160による外部給電、を行なうこともできる。   When the temperature of power storage device 110 is outside the predetermined range, control unit 330 gives priority to (2) external power supply by engine 160 alone. When supply power is insufficient with only the engine, control unit 330 can also perform (3) external power supply by power storage device 110 and engine 160.

これに対し、蓄電装置110の温度が所定範囲内の場合、制御部330は、(1)蓄電装置110のみによる外部給電、(2)エンジン160のみによる外部給電、または(3)蓄電装置110およびエンジン160による外部給電、から最適な外部給電の動作を選択する。(1)〜(3)とのいずれの外部給電動作を行なうかは、外部給電におけるエンジン160の効率を考慮して定めることができる。たとえば、外部給電に要する電力が比較的小さい場合、(1)蓄電装置110のみによる外部給電、が好適と考えられる。一方、外部給電に要する電力が比較的大きい場合、(3)蓄電装置110およびエンジン160による外部給電、が好適と考えられる。なお、蓄電装置110のSOCが比較的低いときは、(2)エンジン160のみによる外部給電、が選択されてもよい。   On the other hand, when the temperature of power storage device 110 is within a predetermined range, control unit 330 may control (1) external power supply using only power storage device 110, (2) external power supply using only engine 160, or (3) power storage device 110 and The optimum external power supply operation is selected from the external power supply by the engine 160. Which external power feeding operation (1) to (3) is performed can be determined in consideration of the efficiency of the engine 160 in the external power feeding. For example, when the power required for external power supply is relatively small, (1) external power supply using only the power storage device 110 is considered preferable. On the other hand, when the power required for external power feeding is relatively large, (3) external power feeding by power storage device 110 and engine 160 is considered preferable. When the SOC of power storage device 110 is relatively low, (2) external power feeding using only engine 160 may be selected.

その他の回路340には、CPU、記憶装置や入出力バッファなどを構成するための回路が含まれる。   The other circuits 340 include circuits for configuring a CPU, a storage device, an input / output buffer, and the like.

先に図1を参照して述べたように、蓄電装置は、たとえば、リチウムイオン電池、ニッケル水素電池または鉛蓄電池などの二次電池、あるいは電気二重層キャパシタなどの蓄電素子を含んで構成される。そのような蓄電装置の特性は、温度によって変化する。たとえば、蓄電装置の温度が高すぎると、蓄電装置が劣化などするおそれがある。蓄電装置の温度は、蓄電装置から取り出す電力(放電電力)および蓄電装置に入力する電力(充電電力)によって上昇し得る。そこで、蓄電装置の温度が高すぎる場合、充放電電力によるさらなる温度の上昇を防ぐために、蓄電装置の充放電電力を制限するような機能が実現される。一方、蓄電池の温度が低すぎると、蓄電装置の充放電電力は低下する。   As described above with reference to FIG. 1, the power storage device includes, for example, a secondary battery such as a lithium ion battery, a nickel hydride battery or a lead storage battery, or a power storage element such as an electric double layer capacitor. . The characteristics of such a power storage device change with temperature. For example, if the temperature of the power storage device is too high, the power storage device may be deteriorated. The temperature of the power storage device can be increased by power (discharge power) extracted from the power storage device and power (charge power) input to the power storage device. Thus, when the temperature of the power storage device is too high, a function of limiting the charge / discharge power of the power storage device is realized in order to prevent further increase in temperature due to the charge / discharge power. On the other hand, when the temperature of the storage battery is too low, the charge / discharge power of the power storage device decreases.

図4は、蓄電装置(たとえば図1の蓄電装置110)が充放電可能な電力と温度との関係を説明するためのグラフである。図4において、横軸は、蓄電池温度(℃)を、縦軸は、許容出力(kW)をそれぞれ示す。縦軸において、許容出力(kW)がプラスのとき、その値は蓄電装置のから取り出すことのできる電力(放電電力)を示す。これに対し、許容出力(kW)がマイナスのとき、その値は蓄電装置に入力することのできる電力(充電電力)を示す。   FIG. 4 is a graph for explaining the relationship between power and temperature that can be charged / discharged by the power storage device (for example, power storage device 110 in FIG. 1). In FIG. 4, the horizontal axis indicates the storage battery temperature (° C.), and the vertical axis indicates the allowable output (kW). On the vertical axis, when the allowable output (kW) is positive, the value indicates the power (discharge power) that can be extracted from the power storage device. On the other hand, when the allowable output (kW) is negative, the value indicates the power (charging power) that can be input to the power storage device.

図4を参照して、蓄電装置の温度がT2(あるいはT2に近い温度)以上かつT1(あるいはT1に近い温度)以下であれば、許容出力は比較的大きくなる。これに対し、蓄電装置の温度がT1(あるいはT1に近い温度)を超えるまたはT2(あるいはT2に近い温度)を下回ると、許容出力は制限される。また、蓄電装置の温度が高温、たとえばT1を上回る温度になると、蓄電装置が劣化するおそれもある。たとえば、蓄電装置110の温度がT1より大きいまたはT2より小さい場合、図3の制御部330は、(2)エンジン160のみによる外部給電動作、を優先させることができる。これにより、蓄電装置の使用頻度を制限し、蓄電装置の温度上昇を防ぐことができる。一方、蓄電装置110の温度がT2以上かつT1以下の場合、制御部330は、蓄電装置の使用を含めた外部給電動作を行ない得る。すなわち、制御部330は、(1)蓄電装置110のみによる外部給電動作、(2)エンジン160のみによる外部給電、または(3)蓄電装置110およびエンジン160による外部給電、から最適な効率の外部給電動作(効率最適モード)を選択することができる。これにより、外部給電の効率を向上させることができる。   Referring to FIG. 4, if the temperature of the power storage device is equal to or higher than T2 (or a temperature close to T2) and equal to or lower than T1 (or a temperature close to T1), the allowable output is relatively large. On the other hand, when the temperature of the power storage device exceeds T1 (or a temperature close to T1) or falls below T2 (or a temperature close to T2), the allowable output is limited. Further, when the temperature of the power storage device is high, for example, higher than T1, the power storage device may be deteriorated. For example, when the temperature of power storage device 110 is higher than T1 or lower than T2, control unit 330 in FIG. 3 can prioritize (2) the external power feeding operation by engine 160 alone. Thereby, the usage frequency of the power storage device can be limited, and the temperature rise of the power storage device can be prevented. On the other hand, when temperature of power storage device 110 is equal to or higher than T2 and equal to or lower than T1, control unit 330 can perform an external power feeding operation including use of the power storage device. In other words, the control unit 330 performs optimal external power feeding from (1) external power feeding operation using only the power storage device 110, (2) external power feeding using only the engine 160, or (3) external power feeding using the power storage device 110 and the engine 160. Operation (efficiency optimum mode) can be selected. Thereby, the efficiency of external power feeding can be improved.

さらに制御部330は、蓄電装置の温度がT2を下回る場合、図1に示す空調装置900を制御する。具体的に、制御部330は、空調装置900の暖房機能を始動させる。これにより、蓄電装置は暖機される。この暖機により蓄電装置の温度がT2以上になれば、蓄電装置の使用を含めた外部給電動作を行なうことが可能になる。   Further, control unit 330 controls air conditioner 900 shown in FIG. 1 when the temperature of the power storage device falls below T2. Specifically, the control unit 330 starts the heating function of the air conditioner 900. Thereby, the power storage device is warmed up. If the temperature of the power storage device becomes equal to or higher than T2 due to this warm-up, external power feeding operation including use of the power storage device can be performed.

図5は、図1および図2の車両100から電気機器700への給電(外部給電)が行なわれるときに実行される制御を説明するためのフローチャートである。このフローチャートの処理は、図1などのECU300で実行される。   FIG. 5 is a flowchart for illustrating control executed when power supply (external power supply) is performed from vehicle 100 in FIG. 1 and FIG. 2 to electric device 700. The process of this flowchart is executed by the ECU 300 in FIG.

図1、図3〜図5を参照して、はじめに、車両100が外部給電モードに設定されているか否かが判断される(ステップS101)。車両100が外部給電モードに設定されている場合(ステップS101でYES)、ステップS102に処理が進められる。一方、車両100が外部給電モードに設定されていない場合(ステップS101でNO)、フローチャートは終了する。   With reference to FIGS. 1 and 3 to 5, first, it is determined whether or not vehicle 100 is set to the external power supply mode (step S <b> 101). If vehicle 100 is set to the external power supply mode (YES in step S101), the process proceeds to step S102. On the other hand, if vehicle 100 is not set to the external power supply mode (NO in step S101), the flowchart ends.

ステップS102において、蓄電装置の温度、たとえば図1の温度センサ800が測定する蓄電装置の外部の気温(外気温)が所定温度T1よりも小さいか否かが判断される。外気温が所定温度T1よりも小さい場合(ステップS102でYES)、ステップS104に処理が進められる。一方、外気温が所定温度T1以上の場合(ステップS102でNO)、ステップS103に処理が進められる。ステップS103において、エンジン160からの給電が優先されて、電気機器700に供給される。その後、ステップS101に再び処理が戻される。   In step S102, it is determined whether or not the temperature of the power storage device, for example, the temperature outside the power storage device (outside temperature) measured by temperature sensor 800 in FIG. 1 is smaller than a predetermined temperature T1. If the outside air temperature is lower than the predetermined temperature T1 (YES in step S102), the process proceeds to step S104. On the other hand, when the outside air temperature is equal to or higher than the predetermined temperature T1 (NO in step S102), the process proceeds to step S103. In step S103, power supply from the engine 160 is prioritized and supplied to the electric device 700. Thereafter, the process returns to step S101 again.

ステップS104では、外気温が所定温度T2よりも大きいか否かが判断される。ステップS104における所定温度T2は、蓄電装置の許容出力がある程度制限される温度である。所定温度T2は、所定温度T1よりも低い温度である。外気温が所定温度T2よりも大きい場合(ステップS104でYES)、ステップS106に処理が進められる。一方、外気温が所定温度T2以下の場合(ステップS104でNO)、ステップS105に処理が進められる。   In step S104, it is determined whether or not the outside air temperature is higher than a predetermined temperature T2. The predetermined temperature T2 in step S104 is a temperature at which the allowable output of the power storage device is limited to some extent. The predetermined temperature T2 is a temperature lower than the predetermined temperature T1. If the outside air temperature is higher than the predetermined temperature T2 (YES in step S104), the process proceeds to step S106. On the other hand, when the outside air temperature is equal to or lower than the predetermined temperature T2 (NO in step S104), the process proceeds to step S105.

ステップS105において、エンジン160からの給電が優先されるとともに、空調装置900の暖房機能が始動される。その後、ステップS101に再び処理が戻される。   In step S105, power supply from the engine 160 is prioritized and the heating function of the air conditioner 900 is started. Thereafter, the process returns to step S101 again.

ステップS106において、効率最適モードで給電が行なわれる。なお、一旦ステップS105によって空調装置900の暖房機能が始動された後、このステップS106に処理が進められる場合もある。その場合、ステップS106においては、外気温が所定温度T2よりも大きいと判断されると、空調装置900の暖房機能が停止されるようにしてもよい。その後、ステップS101に再び処理が戻される。   In step S106, power is supplied in the optimum efficiency mode. Note that after the heating function of the air conditioner 900 is once started in step S105, the process may proceed to step S106. In that case, when it is determined in step S106 that the outside air temperature is higher than the predetermined temperature T2, the heating function of the air conditioner 900 may be stopped. Thereafter, the process returns to step S101 again.

最後に、本発明の実施の形態について総括する。図1および図3を参照して、実施の形態に係るハイブリッド車両の制御装置(ECU300)は、内燃機関(エンジン160)と回転電機(モータジェネレータMG1,MG2)と蓄電装置110とが搭載され外部給電が可能なハイブリッド車両100に用いられる制御装置(ECU300)であって、蓄電装置110の温度に関連する情報を取得する温度情報取得部310と、蓄電装置110の温度が所定範囲を超える場合、蓄電装置110を充電せずに、内燃機関(エンジン160)により回転電機(モータジェネレータMG1,MG2)を駆動させて回転電機(モータジェネレータMG1,MG2)の発電電力をハイブリッド車両100の外部へ供給するようにハイブリッド車両100を制御し、蓄電装置110の温度が所定範囲を超えない場合、蓄電装置110の電力をハイブリッド車両100の外部へ供給するようにハイブリッド車両100を制御する制御部330とを備える。   Finally, embodiments of the present invention will be summarized.
