従来、この種の入出力管理装置としては、充放電可能なバッテリの入出力を管理するものが提案されている（例えば、特許文献１参照）。この装置では、バッテリに充放電される充放電電流の積算値に基づいて演算されるバッテリの残容量とバッテリ温度とに基づいてバッテリの入出力制限を設定し、設定した入出力制限の範囲内でバッテリへの入出力を許可することにより、バッテリへの過大な電力の入出力を抑制している。
特開２００２−３３７５７３号公報 Conventionally, as this type of input / output management device, one that manages input / output of a chargeable / dischargeable battery has been proposed (see, for example, Patent Document 1). In this device, the battery input / output limit is set based on the remaining battery capacity and the battery temperature calculated based on the integrated value of the charge / discharge current charged / discharged to / from the battery, and is within the set input / output limit range. By permitting input / output to / from the battery, excessive power input / output to the battery is suppressed.
JP 2002-337573 A

しかしながら、上述の入出力管理装置では、バッテリの残容量がリセットされたときなど所定の要因が生じたときには、バッテリの入出力制限が適正に設定されず、バッテリの入出力制限を超えた電力がバッテリに入出力されてしまう場合がある。   However, in the above-described input / output management device, when a predetermined factor occurs such as when the remaining capacity of the battery is reset, the input / output limit of the battery is not set appropriately, and the power exceeding the input / output limit of the battery is Input / output may occur in the battery.

本発明の入出力管理装置およびこれを備える駆動装置並びにこれを搭載する自動車、入出力管理方法は、蓄電装置への過大な電力の入出力を抑制することを目的とする。   An object of an input / output management device, a driving device including the input / output management device, a vehicle equipped with the input / output management device, and an input / output management method is to suppress input / output of excessive power to / from the power storage device.

本発明の入出力管理装置およびこれを備える駆動装置並びにこれを搭載する自動車、入出力管理方法は、上述の目的を達成するために以下の手段を採った。   The input / output management device of the present invention, the drive device equipped with the same, the automobile equipped with the same, and the input / output management method employ the following means in order to achieve the above-mentioned object.

本発明の入出力管理装置は、
充放電可能な蓄電手段の入出力を管理する入出力管理装置であって、
前記蓄電手段の状態を検出する状態検出手段と、
所定の補正要因が生じていないときには前記検出された蓄電手段の状態に基づいて該蓄電手段の入出力制限を設定し、前記所定の補正要因が生じているときには前記検出された蓄電手段の状態に基づいて設定される入出力制限に更に制限が課される方向への補正を施して該蓄電手段の入出力制限を設定する入出力制限設定手段と、
該設定された入出力制限の範囲内で前記蓄電手段の入出力を許可する入出力許可手段と、
を備えることを要旨とする。 The input / output management device of the present invention is
An input / output management device for managing input / output of chargeable / dischargeable power storage means,
State detecting means for detecting the state of the power storage means;
When the predetermined correction factor does not occur, the input / output limit of the power storage unit is set based on the detected state of the power storage unit, and when the predetermined correction factor occurs, the detected state of the power storage unit is set. An input / output restriction setting means for setting an input / output restriction of the power storage means by performing correction in a direction in which the restriction is further imposed on the input / output restriction set based on
Input / output permission means for permitting input / output of the power storage means within the set input / output restriction range;
It is a summary to provide.

この本発明の入出力管理装置では、所定の補正要因が生じていないときには、蓄電手段の状態に基づいて蓄電手段の入出力制限を設定すると共に設定した入出力制限の範囲内で蓄電手段の入出力を許可する。一方、所定の補正要因が生じているときには、蓄電手段の状態に基づいて設定される入出力制限に更に制限が課される方向への補正を施して蓄電手段の入出力制限を設定すると共に設定した入出力制限の範囲内で蓄電手段の入出力を許可する。これにより、所定の補正要因が生じているときに蓄電手段に過大な電力が入出力されるのを抑制することができる。   In the input / output management device according to the present invention, when a predetermined correction factor does not occur, the input / output limit of the power storage means is set based on the state of the power storage means, and the input of the power storage means is within the set input / output limit. Allow output. On the other hand, when a predetermined correction factor has occurred, the input / output limit set based on the state of the power storage means is further corrected in a direction in which a limit is imposed, and the input / output limit of the power storage means is set and set. The input / output of the power storage means is permitted within the range of the input / output restriction. Thereby, it is possible to suppress excessive electric power from being input to and output from the power storage means when a predetermined correction factor is generated.

こうした本発明の入出力管理装置において、前記入出力制限設定手段は、前記所定の補正要因が生じているときに、前記蓄電手段の状態を所定の正確さをもって検出することができないときには前記蓄電手段の状態を前記所定の正確さをもって検出することができなくなる直前に検出された蓄電手段の状態に基づいて設定される入出力制限に第１の補正値を用いた補正を施して前記入出力制限を設定し、前記蓄電手段の状態を所定の正確さをもって検出することができるときには該所定の正確さをもって検出された蓄電手段の状態に基づいて設定される入出力制限に前記第１の補正値より小さい第２の補正値を用いた補正を施して前記入出力制限を設定する手段であるものとすることもできる。こうすれば、蓄電手段の状態を所定の正確さをもって検出することができるか否かに応じて蓄電手段の入出力制限を設定することができる。この場合、前記第２の補正値は、時間の経過に伴って徐々に小さくなるよう設定されてなるものとすることもできる。   In such an input / output management device according to the present invention, the input / output restriction setting means may be configured such that when the predetermined correction factor occurs, the power storage means cannot detect the state of the power storage means with a predetermined accuracy. The input / output restriction is corrected by applying a correction using a first correction value to the input / output restriction set based on the state of the power storage means detected immediately before the state cannot be detected with the predetermined accuracy. When the state of the power storage means can be detected with a predetermined accuracy, the first correction value is set to the input / output limit set based on the state of the power storage means detected with the predetermined accuracy. The input / output restriction may be set by performing correction using a smaller second correction value. In this way, it is possible to set the input / output limit of the power storage means depending on whether or not the state of the power storage means can be detected with a predetermined accuracy. In this case, the second correction value may be set so as to gradually decrease with the passage of time.

また、本発明の入出力管理装置において、前記蓄電手段の温度を検出する温度検出手段を備え、前記状態検出手段は前記蓄電手段から放電可能な電力量である蓄電状態を検出する手段であり、前記入出力制限設定手段は前記所定の補正要因が生じていないときには前記検出された蓄電手段の蓄電状態と前記検出された蓄電手段の温度とに基づいて該蓄電手段の入出力制限を設定し前記所定の補正要因が生じているときには前記検出された蓄電手段の蓄電状態と前記検出された蓄電手段の温度とに基づいて設定される入出力制限に更に制限が課される方向への補正を施して該蓄電手段の入出力制限を設定する手段であるものとすることもできる。こうすれば、蓄電手段の入出力制限をより適正に設定することができる。   In the input / output management device of the present invention, the input / output management device includes a temperature detection unit that detects a temperature of the power storage unit, and the state detection unit is a unit that detects a power storage state that is an amount of power that can be discharged from the power storage unit. The input / output restriction setting means sets the input / output restriction of the power storage means based on the detected power storage state of the power storage means and the detected temperature of the power storage means when the predetermined correction factor has not occurred. When a predetermined correction factor has occurred, correction is performed in such a direction that a further restriction is imposed on the input / output restriction set based on the detected power storage state of the power storage means and the detected temperature of the power storage means. Thus, it may be a means for setting an input / output restriction of the power storage means. In this way, the input / output restriction of the power storage means can be set more appropriately.

さらに、本発明の入出力管理装置において、前記所定の補正要因は、入出力管理装置の記憶領域における少なくとも一部がリセットされた要因であるものとすることもできる。こうすれば、入出力管理装置の記憶領域における少なくとも一部がリセットされたときに蓄電手段に過大な電力が入出力されるのを抑制することができる。   Further, in the input / output management device of the present invention, the predetermined correction factor may be a factor that at least a part of the storage area of the input / output management device is reset. In this way, it is possible to prevent excessive power from being input / output to the power storage means when at least a part of the storage area of the input / output management device is reset.

図１は、本発明の一実施例である駆動装置を搭載する電気自動車２０の構成の概略を示す構成図である。実施例の電気自動車２０は、図示するように、駆動輪３０ａ，３０ｂにデファレンシャルギヤ３１を介して連結された駆動軸３２に動力を入出力可能なモータ２２と、モータ２２を駆動するインバータ２４を介してモータ２２と電力のやりとりを行なうバッテリ２６と、車両全体をコントロールする電子制御ユニット４０と、電子制御ユニット４０や補機６１ａ，６１ｂなどに電力供給する電源としての補機バッテリ６０と、を備える。   FIG. 1 is a configuration diagram showing an outline of a configuration of an electric vehicle 20 equipped with a driving apparatus according to an embodiment of the present invention. As shown in the drawing, the electric vehicle 20 of the embodiment includes a motor 22 that can input and output power to a drive shaft 32 connected to drive wheels 30 a and 30 b via a differential gear 31, and an inverter 24 that drives the motor 22. A battery 26 for exchanging electric power with the motor 22, an electronic control unit 40 for controlling the entire vehicle, and an auxiliary battery 60 as a power source for supplying electric power to the electronic control unit 40, the auxiliary machines 61a and 61b, and the like. Prepare.

モータ２２は、例えば、電動機として機能すると共に発電機としても機能する周知の同期発電電動機として構成されている。インバータ２４は、複数のスイッチング素子により構成されており、バッテリ２６から供給される直流電力を擬似的な三相交流電力に変換してモータ２２に供給する。   The motor 22 is configured, for example, as a well-known synchronous generator motor that functions as a motor and also as a generator. The inverter 24 includes a plurality of switching elements, converts the DC power supplied from the battery 26 into pseudo three-phase AC power, and supplies the pseudo three-phase AC power to the motor 22.

電子制御ユニット４０は、ＣＰＵ４２を中心とするマイクロプロセッサとして構成されており、ＣＰＵ４２の他に処理プログラムを記憶するＲＯＭ４４と、データを一時的に記憶するＲＡＭ４６と、図示しない入出力ポートとを備える。このＲＡＭ４６に記憶されたデータは、補機バッテリ６０からの電力供給が遮断されたときには消去される。電子制御ユニット４０には、モータ２２の回転角を検出する回転角センサ２３からの回転角θｍや，バッテリ２６の端子間に設置された電圧センサ２７ａからの端子間電圧Ｖｂ，バッテリ２６に充放電される電流を検出する電流センサ２７ｂからの充放電電流Ｉｂ，バッテリ２６の温度を検出する温度センサ２７ｃからの電池温度Ｔｂ，イグニッションスイッチ５０からのイグニッション信号，シフトレバー５１の操作位置を検出するシフトポジションセンサ５２からのシフトポジションＳＰ，アクセルペダル５３の踏み込み量を検出するアクセルペダルポジションセンサ５４からのアクセル開度Ａｃｃ，ブレーキペダル５５の踏み込み量を検出するブレーキペダルポジションセンサ５６からのブレーキペダルポジションＢＰ，車速センサ５８からの車速Ｖなどが入力ポートを介して入力されている。電子制御ユニット４０からは、モータ２２を駆動制御するためのインバータ２４のスイッチング素子へのスイッチング制御信号などが出力ポートを介して出力されている。なお、電子制御ユニット４０では、バッテリ２６を管理するために、電流センサ２８により検出された充放電電流Ｉｂの積算値に基づいてＣＰＵ４２によりバッテリ２６の残容量ＳＯＣも演算すると共に演算した残容量ＳＯＣをＲＡＭ４６の所定アドレスに記憶する処理も行なっている。   The electronic control unit 40 is configured as a microprocessor centered on the CPU 42, and includes a ROM 44 for storing a processing program, a RAM 46 for temporarily storing data, and an input / output port (not shown) in addition to the CPU 42. The data stored in the RAM 46 is erased when the power supply from the auxiliary battery 60 is cut off. In the electronic control unit 40, the rotation angle θm from the rotation angle sensor 23 that detects the rotation angle of the motor 22, the voltage Vb between the terminals from the voltage sensor 27 a installed between the terminals of the battery 26, and the charge / discharge of the battery 26. The charge / discharge current Ib from the current sensor 27b for detecting the current to be detected, the battery temperature Tb from the temperature sensor 27c for detecting the temperature of the battery 26, the ignition signal from the ignition switch 50, and the shift for detecting the operating position of the shift lever 51 The shift position SP from the position sensor 52, the accelerator opening Acc from the accelerator pedal position sensor 54 that detects the depression amount of the accelerator pedal 53, and the brake pedal position BP from the brake pedal position sensor 56 that detects the depression amount of the brake pedal 55 , Vehicle speed sensor 5 And a vehicle speed V from are input via the input port. From the electronic control unit 40, a switching control signal to the switching element of the inverter 24 for driving and controlling the motor 22 is output via an output port. In the electronic control unit 40, in order to manage the battery 26, the CPU 42 calculates the remaining capacity SOC of the battery 26 and calculates the remaining capacity SOC based on the integrated value of the charge / discharge current Ib detected by the current sensor 28. Is also stored at a predetermined address in the RAM 46.

次に、こうして構成された電気自動車２０の動作について説明する。図２は、実施例の電気自動車２０の電子制御ユニット４０により実行される駆動制御ルーチンの一例を示すフローチャートである。このルーチンは、所定時間毎（例えば、数ｍｓｅｃ毎）に繰り返し実行される。   Next, the operation of the electric vehicle 20 configured as described above will be described. FIG. 2 is a flowchart illustrating an example of a drive control routine executed by the electronic control unit 40 of the electric vehicle 20 according to the embodiment. This routine is repeatedly executed every predetermined time (for example, every several msec).

駆動制御ルーチンが実行されると、電子制御ユニット４０のＣＰＵ４２は、まず、アクセルペダルポジションセンサ５４からのアクセル開度Ａｃｃや，車速センサ５８からの車速Ｖ，モータ２２の回転数Ｎｍ，温度センサ２７ｃからの電池温度Ｔｂ，バッテリ２６の残容量ＳＯＣなどのデータを入力する処理を実行する（ステップＳ１００）。ここで、モータ２２の回転数Ｎｍは、図示しない回転数算出ルーチンにより回転角センサ２３によって検出される回転角θｍに基づいて算出されるものを入力するものとしたり、車速Ｖから換算されるものを入力するものとしたりすることができる。また、バッテリ２６の残容量ＳＯＣは、電流センサ２７ｂにより検出された充放電電流Ｉｂの積算値に基づいて計算されてＲＡＭ４６の所定アドレスに書き込まれたものを入力するものとした。   When the drive control routine is executed, first, the CPU 42 of the electronic control unit 40 first determines the accelerator opening Acc from the accelerator pedal position sensor 54, the vehicle speed V from the vehicle speed sensor 58, the rotational speed Nm of the motor 22, and the temperature sensor 27c. A process of inputting data such as the battery temperature Tb and the remaining capacity SOC of the battery 26 is executed (step S100). Here, the rotation speed Nm of the motor 22 is input based on a rotation angle θm detected by the rotation angle sensor 23 by a rotation speed calculation routine (not shown) or converted from the vehicle speed V. Can be entered. Further, the remaining capacity SOC of the battery 26 is calculated based on the integrated value of the charging / discharging current Ib detected by the current sensor 27b, and is inputted at a predetermined address in the RAM 46.

こうしてデータを入力すると、アクセル開度Ａｃｃと車速Ｖとに基づいて駆動輪３０ａ，３０ｂに連結された駆動軸３２に出力すべき要求トルクＴｄ＊を設定する（ステップＳ１１０）。ここで、要求トルクＴｄ＊は、実施例では、アクセル開度Ａｃｃと車速Ｖと要求トルクＴｄ＊との関係を予め定めて要求トルク設定用マップとしてＲＯＭ４４に記憶しておき、アクセル開度Ａｃｃと車速Ｖとが与えられると記憶したマップから対応する要求トルクＴｄ＊を導出して設定するものとした。要求トルク設定用マップの一例を図３に示す。   When the data is thus input, the required torque Td * to be output to the drive shaft 32 connected to the drive wheels 30a, 30b is set based on the accelerator opening Acc and the vehicle speed V (step S110). Here, in the embodiment, the required torque Td * is determined in advance by storing the relationship between the accelerator opening Acc, the vehicle speed V, and the required torque Td * in the ROM 44 as a required torque setting map. When the vehicle speed V is given, the corresponding required torque Td * is derived from the stored map and set. An example of the required torque setting map is shown in FIG.

次に、残容量リセットフラグＦ１の値を調べると共に（ステップＳ１２０）、残容量リセットフラグＦ１が値０のときには、バッテリ２６の残容量ＳＯＣがリセットされたか否かを判定する（ステップＳ１３０）。ここで、残容量リセットフラグＦ１は、初期値として値０が設定されると共に残容量ＳＯＣがリセットされたときに値１が設定されるフラグである。また、残容量ＳＯＣがリセットされたか否かの判定は、実施例では、入力した残容量ＳＯＣが初期値であるか否かなどを調べることにより行なうものとした。   Next, the value of the remaining capacity reset flag F1 is checked (step S120), and if the remaining capacity reset flag F1 is 0, it is determined whether or not the remaining capacity SOC of the battery 26 has been reset (step S130). Here, the remaining capacity reset flag F1 is a flag in which a value 0 is set as an initial value and a value 1 is set when the remaining capacity SOC is reset. In the embodiment, whether or not the remaining capacity SOC has been reset is determined by checking whether or not the input remaining capacity SOC is an initial value.

バッテリ２６の残容量ＳＯＣがリセットされていないと判定されたときには、バッテリ２６の電池温度Ｔｂとバッテリ２６の残容量ＳＯＣとに基づいてバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定すると共に（ステップＳ１４０）、補正値αに値０を設定し（ステップＳ１５０）、設定した仮入出力制限Ｗｉｎｔｍｐに補正値αを加えることによりバッテリ２６の入力制限Ｗｉｎを計算すると共に仮出力制限Ｗｏｕｔｔｍｐから補正値αを減じることによりバッテリ２６の出力制限Ｗｏｕｔを計算する（ステップＳ２８０）。ここで、バッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐについては、実施例では、電池温度Ｔｂに基づいて仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐの基本値を設定し、残容量ＳＯＣに基づいて仮出力制限用補正係数と仮入力制限用補正係数とを設定し、設定した仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐの基本値に補正係数を乗じて仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定するものとした。図４にバッテリ２６の電池温度Ｔｂとバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐの基本値との関係の一例を示し、図５にバッテリ２６の残容量ＳＯＣとバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐの補正係数との関係の一例を示す。   When it is determined that the remaining capacity SOC of the battery 26 has not been reset, the temporary input / output limits Wintmp, Wouttmp of the battery 26 are set based on the battery temperature Tb of the battery 26 and the remaining capacity SOC of the battery 26 (step) S140), the correction value α is set to 0 (step S150), the correction value α is added to the set temporary input / output limit Wintmp to calculate the input limit Win of the battery 26, and the correction value α is calculated from the temporary output limit Wouttmp. The output limit Wout of the battery 26 is calculated by subtracting (step S280). Here, regarding the temporary input / output limits Wintmp, Wouttmp of the battery 26, in the embodiment, the basic values of the temporary input / output limits Wintmp, Wouttmp are set based on the battery temperature Tb, and the temporary output limits are set based on the remaining capacity SOC. The correction coefficient and the temporary input restriction correction coefficient are set, and the temporary input / output restrictions Wintmp and Wouttmp are set by multiplying the basic value of the set temporary input / output restrictions Wintmp and Wouttmp by the correction coefficient. FIG. 4 shows an example of the relationship between the battery temperature Tb of the battery 26 and the basic values of the temporary input / output limits Wintmp and Wouttmp of the battery 26, and FIG. 5 shows the remaining capacity SOC of the battery 26 and the temporary input / output limits Wintmp, An example of the relationship with the correction coefficient of Wouttmp is shown.

こうしてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定すると、設定した入出力制限Ｗｉｎ，Ｗｏｕｔをモータ２２の回転数Ｎｍで除することによりモータ２２から出力してもよいトルクの上下限としてのトルク制限Ｔｍｉｎ，Ｔｍａｘを計算し（ステップＳ２９０）、計算したトルク制限Ｔｍｉｎ，Ｔｍａｘで要求トルクＴｄ＊を制限してモータ２２のトルク指令Ｔｍ＊を設定し（ステップＳ３００）、設定したトルク指令Ｔｍ＊でモータ２２を駆動制御して（ステップＳ３１０）、駆動制御ルーチンを終了する。モータ２２の駆動制御は、具体的には、トルク指令Ｔｍ＊でモータ２２が駆動されるようインバータ２４のスイッチング素子をスイッチング制御することにより行なわれる。   When the input / output limits Win and Wout of the battery 26 are thus set, the torque limits as upper and lower limits of the torque that may be output from the motor 22 by dividing the set input / output limits Win and Wout by the rotation speed Nm of the motor 22. Tmin and Tmax are calculated (step S290), the required torque Td * is limited by the calculated torque limits Tmin and Tmax, the torque command Tm * of the motor 22 is set (step S300), and the motor is set by the set torque command Tm *. 22 is controlled (step S310), and the drive control routine is terminated. Specifically, the drive control of the motor 22 is performed by switching control of the switching element of the inverter 24 so that the motor 22 is driven by the torque command Tm *.

一方、ステップＳ１３０でバッテリ２６の残容量ＳＯＣがリセットされたと判定されたときには、残容量リセットフラグＦ１に値１を設定すると共に（ステップＳ１６０）、ステップＳ１００で入力したバッテリ２６の残容量ＳＯＣが正確であるか否かを判定する（ステップＳ１７０）。また、ステップＳ１２０で残容量リセットフラグＦ１が値１のときには、バッテリ２６の残容量ＳＯＣがリセットされたか否かを判定せずにバッテリ２６の残容量ＳＯＣが正確であるか否かを判定する（ステップＳ１７０）。バッテリ２６の残容量ＳＯＣが正確であるか否かの判定は、例えば、ステップＳ１００で入力した残容量ＳＯＣとバッテリ２６の端子間電圧Ｖｂから設定される残容量ＳＯＣとの偏差が所定範囲内であるか否かを判定することにより行なうことができる。ここで、端子間電圧Ｖｂから設定される残容量ＳＯＣについては、実施例では、端子間電圧Ｖｂと残容量ＳＯＣとの関係を予め実験的に定めてマップとしてＲＯＭ４４に記憶しておき、電圧センサ２７ａにより検出される端子間電圧Ｖｂと記憶したマップとを用いて残容量ＳＯＣを導出して設定するものとした。また、所定範囲はバッテリ２６の特性などにより定められる。   On the other hand, when it is determined in step S130 that the remaining capacity SOC of the battery 26 has been reset, a value 1 is set in the remaining capacity reset flag F1 (step S160), and the remaining capacity SOC of the battery 26 input in step S100 is accurate. It is determined whether or not (step S170). When the remaining capacity reset flag F1 is 1 in step S120, it is determined whether or not the remaining capacity SOC of the battery 26 is accurate without determining whether or not the remaining capacity SOC of the battery 26 has been reset ( Step S170). The determination as to whether or not the remaining capacity SOC of the battery 26 is accurate is made, for example, when the deviation between the remaining capacity SOC input in step S100 and the remaining capacity SOC set from the inter-terminal voltage Vb of the battery 26 is within a predetermined range. This can be done by determining whether or not there is. Here, regarding the remaining capacity SOC set from the inter-terminal voltage Vb, in the embodiment, the relationship between the inter-terminal voltage Vb and the remaining capacity SOC is experimentally determined in advance and stored in the ROM 44 as a map. The remaining capacity SOC is derived and set using the inter-terminal voltage Vb detected by 27a and the stored map. The predetermined range is determined by the characteristics of the battery 26 and the like.

バッテリ２６の残容量ＳＯＣが正確でないと判定されたときには、残容量格納フラグＦ２の値を調べ（ステップ１８０）、残容量格納フラグＦ２が値０のときには、前回このルーチンが実行されたときに入力されたバッテリ２６の残容量（前回ＳＯＣ）を格納値ＳＯＣｓｅｔとして格納し（ステップＳ１９０）、残容量格納フラグＦ２に値１を設定する（ステップＳ２００）。ここで、残容量格納フラグＦ２は、初期値として値０が設定されると共に残容量ＳＯＣが正確でないと初めて判定されて前回の残容量（前回ＳＯＣ）が格納されたときに値１が設定されるフラグである。また、ステップＳ１９０の処理は、残容量ＳＯＣが正確でないと判定される直前の残容量ＳＯＣを格納する処理となる。そして、格納した格納値ＳＯＣｓｅｔとバッテリ２６の温度Ｔｂとを用いて前述のステップＳ１４０の処理と同様にバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定し（ステップＳ２１０）、補正値αに値Ｗ１を設定し（ステップＳ２２０）、設定したバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐと補正値αとを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定し（ステップＳ２８０）、設定した入出力制限Ｗｉｎ，Ｗｏｕｔの範囲内でモータ２２を駆動制御する（ステップＳ２９０〜Ｓ３１０）。ここで、所定値Ｗ１は、バッテリ２６の残容量ＳＯＣが正確でないと判定される直前の残容量ＳＯＣに基づいて設定される仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限が課される方向に補正する程度を示すものであり、バッテリ２６の特性などにより定められ、例えば、仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐの６０％や７０％などに設定される。一方、ステップＳ１８０で残容量格納フラグＦ２が値１のときには、ステップＳ１９０，Ｓ２００の処理を行なうことなく、バッテリ２６の残容量ＳＯＣが正確でないと判定される直前の残容量ＳＯＣを用いて前述のステップＳ２１０以降の処理を実行する。このように、バッテリ２６の残容量ＳＯＣが正確でないときには、残容量ＳＯＣが正確でないと判定される直前の残容量ＳＯＣを用いてバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定すると共に設定した仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定することにより、バッテリ２６の残容量ＳＯＣが正確でないときにバッテリ２６に過大な電力が入出力されるのを抑制することができる。   When it is determined that the remaining capacity SOC of the battery 26 is not accurate, the value of the remaining capacity storage flag F2 is checked (step 180), and when the remaining capacity storage flag F2 is 0, it is input when this routine is executed last time. The stored remaining capacity (previous SOC) of the battery 26 is stored as a stored value SOCset (step S190), and a value 1 is set to the remaining capacity storage flag F2 (step S200). Here, the remaining capacity storage flag F2 is set to a value 1 when the value 0 is set as an initial value and the remaining capacity SOC is first determined to be inaccurate and the previous remaining capacity (previous SOC) is stored. Flag. Further, the process of step S190 is a process of storing the remaining capacity SOC immediately before it is determined that the remaining capacity SOC is not accurate. Then, using the stored value SOCset and the temperature Tb of the battery 26, the temporary input / output limits Wintmp and Wouttmp of the battery 26 are set in the same manner as in the process of step S140 described above (step S210), and the value W1 is set as the correction value α. (Step S220), the input / output limits Win and Wout of the battery 26 are set using the temporary input / output limits Wintmp and Wouttmp of the battery 26 and the correction value α (step S280). The motor 22 is driven and controlled within the range of Win and Wout (steps S290 to S310). Here, the predetermined value W1 corrects the temporary input / output limits Wintmp, Wouttmp set based on the remaining capacity SOC immediately before it is determined that the remaining capacity SOC of the battery 26 is not accurate in a direction in which further restrictions are imposed. It indicates the degree, is determined by the characteristics of the battery 26, and is set to 60% or 70% of the temporary input / output limits Wintmp, Wouttmp, for example. On the other hand, when the remaining capacity storage flag F2 has a value of 1 in step S180, the above-described processing is performed using the remaining capacity SOC immediately before it is determined that the remaining capacity SOC of the battery 26 is not accurate without performing the processing of steps S190 and S200. The process after step S210 is executed. As described above, when the remaining capacity SOC of the battery 26 is not accurate, the temporary input / output limits Wintmp, Wouttmp of the battery 26 are set and set using the remaining capacity SOC immediately before it is determined that the remaining capacity SOC is not accurate. By correcting the input / output limits Wintmp, Wouttmp in the direction of further limiting and setting the input / output limits Win, Wout of the battery 26, excessive power is input / output to the battery 26 when the remaining capacity SOC of the battery 26 is not accurate.

ステップＳ１７０でバッテリ２６の残容量ＳＯＣが正確であると判定されたときには、前述のステップＳ１４０と同様にバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定すると共に（ステップＳ２３０）、前回の補正値（前回α）から所定値Δαを減じることにより補正値αを設定し（ステップＳ２４０）、設定した補正値αを値０と比較し（ステップＳ２５０）、補正値αが値０以上のときには、設定したバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐと補正値αとを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定し（ステップＳ２８０）、設定した入出力制限Ｗｉｎ，Ｗｏｕｔの範囲内でモータ２２を駆動制御する（ステップＳ２９０〜Ｓ３１０）。ここで、所定値Δαは、バッテリ２６の特性などにより定められ、前述の所定値Ｗ１より小さい値に設定される。こうして補正値αを徐々に小さくしていき、即ち、バッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを電池温度Ｔｂと残容量ＳＯＣとに基づいて設定される仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｍｐに近づけていき、補正値αが値０未満になったときには、補正値αに値０を再設定すると共に（ステップＳ２６０）、残容量リセットフラグＦ１と残容量格納フラグＦ２とに共に値０を設定し（ステップＳ２７０）、設定した仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐと補正値αとを用いて入出力制限Ｗｉｎ，Ｗｏｕｔを計算し（ステップＳ２８０）、入出力制限Ｗｉｎ，Ｗｏｕｔの範囲内でモータ２２を駆動制御する（ステップＳ２９０〜Ｓ３１０）。こうして残容量リセットフラグＦ１と残容量格納フラグＦ２とに共に値０が設定されると、次回にこのルーチンが実行されたときには、ステップＳ１３０で残容量リセットフラグＦ１が値０であるとしてステップＳ１４０でバッテリ２６の残容量ＳＯＣがリセットされたか否かの判定が行なわれる。このように、バッテリ２６の残容量ＳＯＣがリセットされたときに残容量ＳＯＣが正確であるときには、補正値αが値０になるまで電池温度Ｔｂと残容量ＳＯＣとに基づいて設定される仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するのである。   When it is determined in step S170 that the remaining capacity SOC of the battery 26 is accurate, the temporary input / output limits Wintmp, Wouttmp of the battery 26 are set (step S230), and the previous correction value ( The correction value α is set by subtracting the predetermined value Δα from the previous α) (step S240), the set correction value α is compared with the value 0 (step S250), and when the correction value α is greater than or equal to 0, the correction value α is set. Using the temporary input / output limits Wintmp, Wouttmp of the battery 26 and the correction value α, the input / output limits Win, Wout of the battery 26 are set (step S280), and the motor 22 is operated within the set input / output limits Win, Wout. Drive control is performed (steps S290 to S310). Here, the predetermined value Δα is determined by the characteristics of the battery 26 and the like, and is set to a value smaller than the predetermined value W1. In this way, the correction value α is gradually reduced, that is, the input / output limits Win, Wout of the battery 26 are made closer to the temporary input / output limits Wintmp, Woutmp set based on the battery temperature Tb and the remaining capacity SOC, When the correction value α is less than 0, the value 0 is reset to the correction value α (step S260), and the value 0 is set to both the remaining capacity reset flag F1 and the remaining capacity storage flag F2 (step S270). ), Input / output limits Win, Wout are calculated using the set temporary input / output limits Wintmp, Wouttmp and the correction value α (step S280), and the motor 22 is driven and controlled within the range of the input / output limits Win, Wout (step S280). Steps S290 to S310). Thus, when the remaining capacity reset flag F1 and the remaining capacity storage flag F2 are both set to 0, the next time this routine is executed, the remaining capacity reset flag F1 is assumed to be 0 in step S130, and in step S140. It is determined whether or not the remaining capacity SOC of the battery 26 has been reset. As described above, when the remaining capacity SOC is accurate when the remaining capacity SOC of the battery 26 is reset, the provisional input set based on the battery temperature Tb and the remaining capacity SOC until the correction value α reaches the value 0. The input / output limits Win and Wout of the battery 26 are set by correcting the output limits Wintmp and Wouttmp so as to further limit the output limits.

以上説明した実施例の電気自動車２０によれば、バッテリ２６の残容量ＳＯＣがリセットされたときには、バッテリ２６の電池温度Ｔｂと残容量ＳＯＣとに基づいて設定されるバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定すると共に設定した入出力制限Ｗｉｎ，Ｗｏｕｔの範囲内でモータ２２を駆動制御するから、残容量ＳＯＣがリセットされたときにバッテリ２６に過大な電力が入出力されるのを抑制することができる。   According to the electric vehicle 20 of the embodiment described above, when the remaining capacity SOC of the battery 26 is reset, the temporary input / output limit Wintmp of the battery 26 set based on the battery temperature Tb of the battery 26 and the remaining capacity SOC. , Wouttmp is corrected in a further restricting direction, and the input / output limits Win and Wout of the battery 26 are set and the motor 22 is driven and controlled within the set input / output limits Win and Wout, so that the remaining capacity SOC is reset. It is possible to prevent excessive electric power from being input / output to / from the battery 26 at the time.

実施例の電気自動車２０では、バッテリ２６の電池温度Ｔｂと残容量ＳＯＣとに基づいて仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定するものとしたが、バッテリ２６の残容量ＳＯＣだけに基づいて仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定するものとしてもよいし、電池温度Ｔｂや残容量ＳＯＣに加えて他のパラメータを考慮して仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを設定するものとしてもよい。   In the electric vehicle 20 of the embodiment, the temporary input / output limits Wintmp, Wouttmp are set based on the battery temperature Tb of the battery 26 and the remaining capacity SOC, but the temporary input / output is based only on the remaining capacity SOC of the battery 26. The limits Wintmp and Wouttmp may be set, or the temporary input / output limits Wintmp and Wouttmp may be set in consideration of other parameters in addition to the battery temperature Tb and the remaining capacity SOC.

実施例の電気自動車２０では、図２の駆動制御ルーチンのステップＳ１７０，Ｓ１８０でバッテリ２６の残容量ＳＯＣが正確でないと判定されると共に残容量格納フラグＦ２が値０のときには、前回このルーチンが実行されたときの残容量（前回ＳＯＣ）を格納値ＳＯＣｓｅｔとして格納するものとしたが、残容量ＳＯＣの初期値を格納値ＳＯＣｓｅｔとして格納するものとしたり、ステップＳ１００で入力した残容量ＳＯＣを格納値ＳＯＣｓｅｔとして格納するものとしてもよい。   In the electric vehicle 20 of the embodiment, when the remaining capacity SOC of the battery 26 is determined to be inaccurate in steps S170 and S180 of the drive control routine of FIG. 2, this routine is executed last time when the remaining capacity storage flag F2 is 0. The remaining capacity (previous SOC) when stored is stored as the stored value SOCset, but the initial value of the remaining capacity SOC is stored as the stored value SOCset, or the remaining capacity SOC input in step S100 is stored. It is good also as what stores as SOCset.

実施例の電気自動車２０では、バッテリ２６の残容量ＳＯＣがリセットされたときに、バッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するものとしたが、これに代えて、イグニッションスイッチ５０がオフされている最中に補機バッテリ６０から電子制御ユニット４０への電力供給が一旦遮断されたときなどに、バッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するものとしてもよい。この場合、補機バッテリ６０からの電力供給が遮断されたときにバッテリ２６の残容量ＳＯＣは消去されたと考えられるため、図２の駆動制御ルーチンのステップＳ１７０，Ｓ１８０でバッテリ２６の残容量ＳＯＣが正確でないと判定されると共に残容量格納フラグＦ２が値０のときには、ステップＳ１９０の処理に代えて、残容量ＳＯＣの初期値を格納値ＳＯＣｓｅｔとして格納するものとしてもよい。また、バッテリ２６の残容量ＳＯＣがリセットされた条件やイグニッションスイッチ５０がオフされている最中に補機バッテリ６０から電子制御ユニット４０への電力供給が一旦遮断された条件などの複数の条件の少なくとも一つが成立したときに、バッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを更に制限する方向に補正してバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するものとしてもよい。   In the electric vehicle 20 of the embodiment, when the remaining capacity SOC of the battery 26 is reset, the temporary input / output limits Wintmp, Wouttmp of the battery 26 are corrected in a direction to further limit the input / output limits Win, Wout of the battery 26. However, instead of this, when the power supply from the auxiliary battery 60 to the electronic control unit 40 is temporarily interrupted while the ignition switch 50 is turned off, the battery 26 is temporarily turned on. The input / output limits Win and Wout of the battery 26 may be set by correcting the output limits Wintmp and Wouttmp so as to further limit the output limits. In this case, since the remaining capacity SOC of the battery 26 is considered to have been deleted when the power supply from the auxiliary battery 60 is cut off, the remaining capacity SOC of the battery 26 is determined in steps S170 and S180 of the drive control routine of FIG. When it is determined that the remaining capacity is not accurate and the remaining capacity storage flag F2 is 0, the initial value of the remaining capacity SOC may be stored as the stored value SOCset instead of the process of step S190. In addition, there are a plurality of conditions such as a condition in which the remaining capacity SOC of the battery 26 is reset and a condition in which the power supply from the auxiliary battery 60 to the electronic control unit 40 is temporarily interrupted while the ignition switch 50 is turned off. When at least one of them is established, the temporary input / output limits Wintmp and Wouttmp of the battery 26 may be corrected in a direction to further limit and the input / output limits Win and Wout of the battery 26 may be set.

実施例の電気自動車２０では、バッテリ２６の残容量ＳＯＣがリセットされたか否かの判定を、入力した残容量ＳＯＣが初期値であるか否かを調べることにより行なうものとしたが、これに代えてまたは加えて、イグニッションスイッチ５０がオフされている最中に補機バッテリ６０から電子制御ユニット４０への電力供給が一旦遮断されたか否かを調べたりすることなどにより行なうものとしてもよい。   In the electric vehicle 20 of the embodiment, the determination as to whether or not the remaining capacity SOC of the battery 26 has been reset is made by examining whether or not the input remaining capacity SOC is an initial value. Alternatively or additionally, it may be performed by checking whether or not the power supply from the auxiliary battery 60 to the electronic control unit 40 is once interrupted while the ignition switch 50 is turned off.

実施例の電気自動車２０では、図２の駆動制御ルーチンのステップＳ１７０で残容量ＳＯＣが正確であると判定されたときには、時間の経過に伴って補正値αを小さくしていくものとしたが、バッテリ２６の残容量ＳＯＣが正確でないときの補正値α（前述の値Ｗ１）以下の値であれば、時間の経過に拘わらず所定値を設定するものとしてもよい。この場合、残容量ＳＯＣがリセットされたと判定されてから所定時間を経過したときに残容量リセットフラグＦ１と残容量格納フラグＦ２とに共に値０を設定するものとしてもよい。   In the electric vehicle 20 of the embodiment, when it is determined that the remaining capacity SOC is accurate in step S170 of the drive control routine of FIG. 2, the correction value α is decreased with the passage of time. A predetermined value may be set regardless of the passage of time as long as it is a value equal to or less than the correction value α (the aforementioned value W1) when the remaining capacity SOC of the battery 26 is not accurate. In this case, the value 0 may be set to both the remaining capacity reset flag F1 and the remaining capacity storage flag F2 when a predetermined time has elapsed since it was determined that the remaining capacity SOC was reset.

実施例の電気自動車２０では、図２の駆動制御ルーチンのステップＳ１２０で残容量リセットフラグＦ１が値１のときやステップＳ１３０でバッテリ２６の残容量ＳＯＣがリセットされたと判定されたときには、残容量ＳＯＣが正確であるか否かに応じて補正値αを設定するものとしたが、残容量ＳＯＣが正確であるか否かに拘わらず所定値（例えば、前述の値Ｗ１など）を補正値αに設定するものとしてもよい。この場合、残容量ＳＯＣがリセットされたと判定されてから所定時間を経過したときに残容量リセットフラグＦ１と残容量格納フラグＦ２とに共に値０を設定するものとしてもよい。   In the electric vehicle 20 of the embodiment, when the remaining capacity reset flag F1 is 1 in step S120 of the drive control routine of FIG. 2 or when it is determined in step S130 that the remaining capacity SOC of the battery 26 is reset, the remaining capacity SOC The correction value α is set according to whether or not the current value is accurate. However, a predetermined value (for example, the aforementioned value W1 or the like) is set as the correction value α regardless of whether or not the remaining capacity SOC is accurate. It may be set. In this case, the value 0 may be set to both the remaining capacity reset flag F1 and the remaining capacity storage flag F2 when a predetermined time has elapsed since it was determined that the remaining capacity SOC was reset.

実施例の電気自動車２０では、図２の駆動制御ルーチンのステップＳ１００で入力した残容量ＳＯＣとバッテリ２６の端子間電圧Ｖｂから設定される残容量ＳＯＣとに基づいてステップＳ１７０でバッテリ２６の残容量ＳＯＣが正確であるか否かを判定するものとしたが、ステップＳ１３０でバッテリ２６の残容量ＳＯＣがリセットされたと判定されてから所定時間を経過したか否かに基づいてバッテリ２６の残容量ＳＯＣが正確であるか否かを判定するものとしてもよい。ここで、所定時間は、バッテリ２６の特性や電子制御ユニット４０の性能などにより定められる。   In the electric vehicle 20 of the embodiment, the remaining capacity of the battery 26 in step S170 based on the remaining capacity SOC input in step S100 of the drive control routine of FIG. 2 and the remaining capacity SOC set from the terminal voltage Vb of the battery 26. Although it is determined whether or not the SOC is accurate, the remaining capacity SOC of the battery 26 is determined based on whether or not a predetermined time has elapsed since it was determined in step S130 that the remaining capacity SOC of the battery 26 was reset. It is good also as what determines whether is correct. Here, the predetermined time is determined by the characteristics of the battery 26, the performance of the electronic control unit 40, and the like.

実施例の電気自動車２０では、図２の駆動制御ルーチンのステップＳ１２０で残容量リセットフラグＦ１が値１のときやステップＳ１３０でバッテリ２６の残容量ＳＯＣがリセットされたと判定されたときには、バッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定する際に共に補正値αを用いて設定するものとしたが、入力制限Ｗｉｎを設定する際に用いる補正値α１と出力制限Ｗｏｕｔを設定する際に用いる補正値α２とに異なる値を用いるものとしてもよい。ここで、補正値α１と補正値α２との関係は、バッテリ２６の特性などにより定めることができる。   In the electric vehicle 20 of the embodiment, when the remaining capacity reset flag F1 is 1 in step S120 of the drive control routine of FIG. 2 or when it is determined in step S130 that the remaining capacity SOC of the battery 26 is reset, Although the input / output limits Win and Wout are both set using the correction value α, the correction value α1 used when setting the input limit Win and the correction value α2 used when setting the output limit Wout are set. Different values may be used. Here, the relationship between the correction value α1 and the correction value α2 can be determined by the characteristics of the battery 26 and the like.

実施例の電気自動車２０では、バッテリ２６の残容量ＳＯＣがリセットされたときに残容量ＳＯＣが正確でないときには、残容量ＳＯＣが正確でないと判定される直前の残容量ＳＯＣを用いて設定されるバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するものとしたが、残容量ＳＯＣが正確でないと判定される直前のバッテリ２６の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するものとしてもよい。この場合の駆動制御ルーチンの一例の一部を図６に示す。なお、図６の駆動制御ルーチンのうち図２の駆動制御ルーチンと同一の処理について同一のステップ番号を付し、その詳細な説明は省略する。図６の駆動制御ルーチンでは、ステップＳ１２０で残容量リセットフラグＦ１が値１のときやステップＳ１３０でバッテリ２６の残容量ＳＯＣがリセットされたと判定されたときには、残容量ＳＯＣが正確であるか否かを判定し（ステップＳ１７０）、残容量ＳＯＣが正確でないと判定されたときには、仮入出力制限格納フラグＦ３の値を調べ（ステップＳ４００）、仮入出力制限格納フラグＦ３が値０のときには、前回このルーチンが実行されたときに設定されたバッテリ２６の仮入出力制限（前回Ｗｉｎｔｍｐ），（前回Ｗｏｕｔｔｍｐ）を格納値Ｗｉｎｓｅｔ，Ｗｏｕｔｓｅｔとして格納すると共に（ステップＳ４１０）、仮入出力制限格納フラグＦ３に値１を設定し（ステップＳ４２０）、格納値Ｗｉｎｓｅｔ，Ｗｏｕｔｓｅｔを仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐに設定し（ステップＳ４３０）、補正値αに値Ｗ１を設定し（ステップＳ２２０）、設定した仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐと補正値αとを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定する（ステップＳ２８０）。ここで、仮入出力制限格納フラグＦ３は、初期値として値０が設定されると共に前回の仮入出力制限（前回Ｗｉｎｔｍｐ），（前回Ｗｏｕｔｔｍｐ）、即ち残容量ＳＯＣが正確でないと判定される直前の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐが格納されたときに値１が設定されるフラグである。ステップＳ４００で仮入出力制限格納フラグＦ３が値１のときには、ステップＳ４１０で格納した格納値Ｗｉｎｓｅｔ，Ｗｏｕｔｓｅｔを用いてＳ４３０以降の処理を実行する。即ち、バッテリ２６の残容量ＳＯＣが正確でないときには、残容量ＳＯＣが正確でないと判定される直前の仮入出力制限Ｗｉｎｔｍｐ，Ｗｏｕｔｔｍｐを用いてバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定するのである。なお、仮入出力制限格納フラグＦ３は、ステップＳ１７０で残容量ＳＯＣが正確であると判定され且つステップＳ２４０で補正値αが値０未満のときに値０にリセットされる（ステップＳ４４０）。このようにバッテリ２６の入出力制限Ｗｉｎ，Ｗｏｕｔを設定することにより、実施例と同様の効果を奏することができる。   In the electric vehicle 20 of the embodiment, when the remaining capacity SOC is not accurate when the remaining capacity SOC of the battery 26 is reset, the battery set using the remaining capacity SOC immediately before it is determined that the remaining capacity SOC is not accurate. The temporary input / output limits Wintmp, Wouttmp of the battery 26 are used to set the input / output limits Win, Wout of the battery 26, but the temporary input / output limits Wintmp of the battery 26 immediately before it is determined that the remaining capacity SOC is not accurate. The input / output limits Win and Wout of the battery 26 may be set using Wouttmp. A part of an example of the drive control routine in this case is shown in FIG. 6 that are the same as those in the drive control routine of FIG. 2 are assigned the same step numbers, and detailed descriptions thereof are omitted. In the drive control routine of FIG. 6, when the remaining capacity reset flag F1 is 1 in step S120 or when it is determined in step S130 that the remaining capacity SOC of the battery 26 has been reset, whether or not the remaining capacity SOC is accurate. (Step S170), when it is determined that the remaining capacity SOC is not accurate, the value of the temporary input / output restriction storage flag F3 is checked (step S400). The temporary input / output limits (previous Wintmp) and (previous Wtmpmp) of the battery 26 set when this routine is executed are stored as stored values Winset and Woutset (step S410), and the temporary input / output limit storage flag F3 is stored. The value 1 is set (step S420), and the stored values Winset, Woutset are temporarily set. The output limits Wintmp, Wouttmp are set (step S430), the value W1 is set as the correction value α (step S220), and the input / output limit of the battery 26 is set using the set temporary input / output limits Wintmp, Wouttmp and the correction value α. Win and Wout are set (step S280). Here, the temporary input / output restriction storage flag F3 is set to an initial value of 0, and immediately before the previous temporary input / output restriction (previous Wintmp), (previous Wouttmp), that is, immediately before it is determined that the remaining capacity SOC is not accurate. This flag is set to 1 when the temporary input / output limits Wintmp, Wouttmp are stored. When the temporary input / output restriction storage flag F3 is 1 in step S400, the processing after S430 is executed using the stored values Winset and Woutset stored in step S410. That is, when the remaining capacity SOC of the battery 26 is not accurate, the input / output limits Win, Wout of the battery 26 are set using the temporary input / output limits Wintmp, Wouttmp immediately before it is determined that the remaining capacity SOC is not accurate. The temporary input / output restriction storage flag F3 is reset to 0 when it is determined in step S170 that the remaining capacity SOC is accurate and the correction value α is less than 0 in step S240 (step S440). By setting the input / output limits Win and Wout of the battery 26 in this way, the same effects as in the embodiment can be obtained.
