Motor generators 32-1 and 32-2 are AC rotating electric machines, for example, permanent magnet type synchronous motors having a rotor in which permanent magnets are embedded. Motor generators 32-1 and 32-2 are connected to power split device 34. Although not shown in detail, power split device 34 includes a planetary gear including a sun gear, a pinion gear, a carrier, and a ring gear. The pinion gear engages with the sun gear and the ring gear. The carrier supports the pinion gear so as to be capable of rotating, and is connected to the crankshaft of the engine 36. The sun gear is coupled to the rotation shaft of motor generator 32-1. The ring gear is connected to the rotation shaft of motor generator 32-2 and drive wheel 38. The power split device 34 divides the mechanical power generated by the engine 36 into a path that is transmitted to the drive wheels 38 and a path that is transmitted to the motor generator 32-1.
そして、モータジェネレータ32-1は、動力分割装置34によって分割されたエンジン36の動力を用いて発電する。たとえば、蓄電装置10のSOCが低下すると、エンジン36が始動してモータジェネレータ32-1により発電が行なわれ、その発電された電力が蓄電装置へ供給される。
The motor generator 32-1 generates power using the power of the engine 36 divided by the power split device 34. For example, when the SOC of power storage device 10 decreases, engine 36 is started and power is generated by motor generator 32-1, and the generated power is supplied to the power storage device.
一方、モータジェネレータ32-2は、蓄電装置10から供給される電力およびモータジェネレータ32-1により発電された電力の少なくとも一方を用いて駆動力を発生する。モータジェネレータ32-2の駆動力は、駆動輪38に伝達される。なお、車両の制動時には、車両の運動エネルギーが駆動輪38からモータジェネレータ32-2に伝達され、モータジェネレータ32-2が発電機として作動する。これにより、モータジェネレータ32-2は、車両の運動エネルギーを電力に変換して回収する回生ブレーキとして作動する。
On the other hand, motor generator 32-2 generates driving force using at least one of the electric power supplied from power storage device 10 and the electric power generated by motor generator 32-1. The driving force of the motor generator 32-2 is transmitted to the driving wheels 38. When the vehicle is braked, the kinetic energy of the vehicle is transmitted from the drive wheels 38 to the motor generator 32-2, and the motor generator 32-2 operates as a generator. Thus, motor generator 32-2 operates as a regenerative brake that converts and recovers the kinetic energy of the vehicle into electric power.
MG-ECU40は、コンバータ12駆動するための信号PWCを生成し、その生成した信号PWC1をコンバータ12へ出力する。また、MG-ECU40は、モータジェネレータ32-1,32-2をそれぞれ駆動するための信号PWI1,PWI2を生成し、その生成した信号PWI1,PWI2をインバータ30へ出力する。

Including. The third threshold value β is smaller than the first threshold value α. Comparing portion 95 outputs signal SMR-OFF for turning off system main relay 11 when the remaining capacity decreases to third threshold value β in order to prevent overdischarge of power storage device 10.

図3は、HV-ECU46において実行されるエアコンおよび電源制御に関する処理を説明するためのフローチャートである。なお、このフローチャートの処理は所定のメインルーチンから一定時間経過ごとまたは所定の条件が成立するごとに呼び出されて実行される。
FIG. 3 is a flowchart for explaining processing relating to the air conditioner and power supply control executed in the HV-ECU 46. The process of this flowchart is called and executed from a predetermined main routine every time a predetermined time elapses or a predetermined condition is satisfied.
図1、図3を参照して、まず処理が開始されると、HV-ECU46は、ステップS1において、残存蓄電量SOCがしきい値α以下であるか否かを判断する。残存蓄電量SOCは、バッテリ電圧VBおよびバッテリ電流IBの変化に基づいて随時算出されている。
Referring to FIG. 1 and FIG. 3, first, when the process is started, HV-ECU 46 determines in step S1 whether or not the remaining charged amount SOC is equal to or less than threshold value α. The remaining power storage amount SOC is calculated as needed based on changes in the battery voltage VB and the battery current IB.
ステップS1においてSOC≦αが成立した場合には、ステップS3に処理が進みエアコンの停止がHV-ECU46からAC-ECU82に要求される。ステップS1においてSOC≦αが成立しなかった場合には、ステップS2に処理が進む。
When SOC ≦ α is established in step S1, the process proceeds to step S3, and the HV-ECU 46 requests the AC-ECU 82 to stop the air conditioner. If SOC ≦ α is not satisfied in step S1, the process proceeds to step S2.
ステップS2では、HV-ECU46は、残存蓄電量SOCがしきい値α+ΔS以上であるか否かを判断する。ステップS2においてSOC≧α+ΔSが成立した場合には、ステップS4に処理が進み、エアコン停止が解除されエアコン80の作動が許可される。一方、ステップS2においてSOC≧α+ΔSが成立しなかった場合には、ステップS5に処理が進み、エアコンの作動許可/禁止状態は現状が維持される。
In step S2, the HV-ECU 46 determines whether or not the remaining power storage amount SOC is equal to or greater than a threshold value α + ΔS. If SOC ≧ α + ΔS is satisfied in step S2, the process proceeds to step S4, the air conditioner stop is released, and the operation of the air conditioner 80 is permitted. On the other hand, if SOC ≧ α + ΔS is not satisfied in step S2, the process proceeds to step S5, and the current state of the air conditioner operation permission / prohibition state is maintained.
ステップS3,S4,S5のいずれかの処理が終了した場合にはステップS6に処理が進む。ステップS6では、HV-ECU46は、残存蓄電量SOCがしきい値β以下であるか否かを判断する。ステップS6においてSOC≦βが成立した場合には、ステップS7に処理が進み、バッテリ電流IBをモニタして蓄電装置10に充電が行なわれているか否かがさらに判断される。充電が行なわれていれば、残存蓄電量SOCは次第に回復していくことが期待されるので、ステップS10に処理が進み制御はメインルーチンに戻される。
If any of steps S3, S4 and S5 is completed, the process proceeds to step S6. In step S6, the HV-ECU 46 determines whether or not the remaining charged amount SOC is equal to or less than the threshold value β. If SOC ≦ β is satisfied in step S6, the process proceeds to step S7, where battery current IB is monitored to further determine whether or not power storage device 10 is charged. If charging is being performed, the remaining power storage SOC is expected to gradually recover, so that the process proceeds to step S10 and control returns to the main routine.
一方、ステップS7においてバッテリ電流IBがゼロであるか、放電を示す場合には、蓄電装置10に充電が行なわれていない。この場合にはステップS8に処理が進み、HV-ECU46は、システムメインリレー11をオフ状態とし、蓄電装置10が過放電にならないように保護する。そしてステップS9に処理が進み、制御終了となる。
On the other hand, if the battery current IB is zero or indicates discharging in step S7, the power storage device 10 is not charged. In this case, the process proceeds to step S8, and HV-ECU 46 turns off system main relay 11 to protect power storage device 10 from being overdischarged. Then, the process proceeds to step S9, and the control ends.
図1、図3を再び参照して、本実施の形態の車両の制御方法について総括する。本実施の形態の制御方法は、車両外部から充電が可能に構成された蓄電装置10(10)を搭載する車両の制御方法である。車両100は車室を空調するエアコン80を含む。制御方法は、蓄電装置10の充電中においてエアコン80の動作によって蓄電装置10の残存蓄電量が第1のしきい値αまで低下した場合にはエアコン80の動作を制限するステップ(S3)と、エアコン80を停止させた後に残存蓄電量が第1のしきい値αよりも大きい第2のしきい値α+ΔSまで回復した場合にはエアコン80の制限前の動作を再開させるステップ(S4)とを含む。
Referring to FIGS. 1 and 3 again, the vehicle control method of the present embodiment will be summarized. The control method of the present embodiment is a control method for a vehicle on which power storage device 10 (10) configured to be rechargeable from the outside of the vehicle is mounted. The vehicle 100 includes an air conditioner 80 that air-conditions the passenger compartment. The control method includes a step (S3) of restricting the operation of the air conditioner 80 when the remaining power storage amount of the power storage device 10 is reduced to the first threshold value α by the operation of the air conditioner 80 during the charging of the power storage device 10. A step (S4) of restarting the operation before the restriction of the air conditioner 80 when the remaining power storage amount is recovered to the second threshold value α + ΔS larger than the first threshold value α after the air conditioner 80 is stopped. Including.
好ましくは、制御方法は、蓄電装置10の過放電を防止するために残存容量が第3のしきい値βまで低下した場合には車両100の電源系統をシャットダウンするステップ(S6,S8)をさらに備える。第3のしきい値βは第1のしきい値αよりも小さい。
Preferably, the control method further includes a step (S6, S8) of shutting down the power supply system of vehicle 100 when the remaining capacity is reduced to third threshold value β in order to prevent overdischarge of power storage device 10. Prepare. The third threshold value β is smaller than the first threshold value α.
なお、図3のフローチャートはエアコン80について停止要求と停止解除を行なう場合を示したが、エアコン80以外の補機装置について停止要求と停止解除を同様に行なうものであっても良い。エアコン80以外の補機装置としては、たとえば、エアコン以外でも車室内の快適性を高める装備(たとえば、オーディオ機器、照明など)、充電中でも作動させる可能性があるもの(サービスコンセントから交流電力を出力するためのDC/AC変換器、カーナビゲーション装置)が挙げられる。
Although the flowchart of FIG. 3 shows the case where the stop request and the stop release are performed for the air conditioner 80, the stop request and the stop release may be similarly performed for the auxiliary devices other than the air conditioner 80. As auxiliary equipment other than air conditioner 80, for example, equipment other than air conditioner that enhances comfort in the passenger compartment (for example, audio equipment, lighting, etc.), equipment that may be operated even during charging (output AC power from service outlet) DC / AC converter and car navigation device).
図4は、本実施の形態の車両の制御装置がエアコンの制御を行なった一例を説明するための動作波形図である。
FIG. 4 is an operation waveform diagram for explaining an example in which the vehicle control device of the present embodiment controls the air conditioner.
図1、図4を参照して、時刻t1までは、外部充電が行なわれていてもエアコン80などの車両負荷での消費電力が入力電力よりも大きいため、蓄電装置10の残存蓄電量SOCは減少していく。そして、時刻t1においてSOCはしきい値αに到達する。
Referring to FIGS. 1 and 4, until time t <b> 1, power consumption at the vehicle load such as air conditioner 80 is larger than input power even if external charging is performed, so that the remaining power storage SOC of power storage device 10 is Decrease. At time t1, the SOC reaches the threshold value α.
このとき、本実施の形態の制御装置が適用されていない車両であれば、たとえば波形W2に示すように、システムの停止条件であるしきい値βまで放電が許容され、そして時刻t2においてSOCがしきい値βに到達した時点でエアコン運転が禁止され、図示しないがシステムメインリレー11はオフ状態に変更され車両のシステムは停止される。
At this time, if the vehicle is not applied with the control device of the present embodiment, for example, as shown in waveform W2, discharge is allowed up to threshold value β, which is a system stop condition, and SOC at time t2 When the threshold value β is reached, the air-conditioner operation is prohibited, and although not shown, the system main relay 11 is changed to an off state and the vehicle system is stopped.
本実施の形態の制御装置(HV-ECU46)は、時刻t1においてSOCがしきい値αに到達すると、エアコンの運転を一旦停止させる。外部電源58からの充電が蓄電装置10に行なわれることにより、時刻t1~t3の間はSOCは増加し、時刻t3においてしきい値(α+ΔS)まで回復する。
The control device (HV-ECU 46) of the present embodiment temporarily stops the operation of the air conditioner when the SOC reaches the threshold value α at time t1. When power storage device 10 is charged from external power supply 58, the SOC increases between times t1 and t3, and recovers to the threshold value (α + ΔS) at time t3.
時刻t3においてHV-ECU46は、エアコンの運転を再開させる。このように、エアコンのオンオフが繰返される結果、時刻t3~t4,t5~t6,t7~t8の間はエアコンが運転許可され、時刻t4~t5,t6~t7,t8~では、エアコンの運転は禁止される。
At time t3, the HV-ECU 46 resumes the operation of the air conditioner. As described above, the air conditioner is repeatedly turned on and off. As a result, the air conditioner is permitted to operate from time t3 to t4, t5 to t6, t7 to t8, and from time t4 to t5, t6 to t7, t8, It is forbidden.
冷房時であれば、本実施の形態の制御装置が適用されていない車両であれば、たとえば波形T2に示すように、エアコン80が停止してしまうと、そのままずっと運転再開されないので、エアコンや車両の設定スイッチによってエアコンを動作させない限りは、車室の温度は上昇を続けてしまう可能性がある。
During cooling, if the vehicle is not applied with the control device of the present embodiment, for example, as shown by the waveform T2, if the air conditioner 80 stops, the operation is not resumed as it is. Unless the air conditioner is operated by the setting switch, the passenger compartment temperature may continue to rise.
本実施の形態の制御装置が適用されている車両であれば、目標値よりはΔT高い温度となってしまうけれども、波形T1に示すように、車室の温度は上昇し続けることはなくなる。
In the case of a vehicle to which the control device of the present embodiment is applied, although the temperature is higher by ΔT than the target value, the temperature of the passenger compartment does not continue to rise as shown by the waveform T1.
以上説明したように、本実施の形態の制御装置によれば、外部充電時において冷房によって車室の温度を適温にしようとしていた場合には、空調装置が間欠動作を行なうので、蓄電装置の過放電を防止しつつ、車室の温度が過度に上昇してしまうことを防止することができる。また、暖房使用時であれば、空調装置が間欠動作を行なうので、蓄電装置の過放電を防止しつつ、車室の温度が過度に低温になってしまうことを防止することができる。
As described above, according to the control device of the present embodiment, when the temperature of the passenger compartment is set to an appropriate temperature by cooling during external charging, the air conditioner performs an intermittent operation. While preventing discharge, it is possible to prevent the temperature of the passenger compartment from rising excessively. In addition, since the air conditioner performs an intermittent operation when heating is used, it is possible to prevent the temperature of the passenger compartment from becoming excessively low while preventing overdischarge of the power storage device.
