The starter motor 90 is a motor for starting the engine.
　次に本実施形態の概略を説明する。
　アイドリングストップ状態からエンジンを再起動させる場合、エンジンのクランクシャフトを回転させる、クランキングと呼ばれる動作が必要となる。この回転力を与えるためにスタータモータ９０を駆動するが、そのままではバッテリ電圧が下がるので、昇圧回路２０により電装部品に供給する電圧を昇圧させる。しかし、昇圧しても燃料不足やエンジンの不具合によりクランキング時間が長くなると、スタータモータ９０での電力消費等により電圧が低下することがある。このようなロングクランキングが発生すると、電装部品の電源が必要電圧以下となり、電装部品が突然に機能停止するという現象につながる。
　一方、エンジンを再起動させる場合は常に電装部品の機能を制限すると、車両の商品性が低下する。 Next, an outline of the present embodiment will be described.
When restarting the engine from the idling stop state, an operation called cranking that rotates the engine crankshaft is required. The starter motor 90 is driven to apply this rotational force, but since the battery voltage drops as it is, the voltage supplied to the electric component is boosted by the booster circuit 20. However, even if the pressure is increased, if the cranking time is lengthened due to a lack of fuel or a malfunction of the engine, the voltage may decrease due to the power consumption of the starter motor 90 and the like. When such long cranking occurs, the power supply of the electric component becomes lower than the required voltage, which leads to a phenomenon that the electric component suddenly stops functioning.
On the other hand, when restarting the engine, if the functions of the electrical components are always limited, the vehicle's commodity property is reduced.
　本実施形態では、ロングクランキングが発生している又は発生する可能性が高い、という状況を検出した後に、電装部品の出力を抑制する又は電装部品の作動を停止することで、電装部品がなるべく機能低下しないようにする。
　ロングクランキングが発生している又は発生する可能性が高い状況を判断するために、スタータモータ９０が作動中であり、かつ昇圧中である、という状況を用いる。そこで、スタータモータ９０作動中で昇圧開始から時間を計測し、所定の時間閾値以上となれば実際にロングクランキングが発生した又はロングクランキングが発生しそうであると判定する。または、昇圧中でスタータモータ９０の作動時間を計測し、所定の時間閾値以上となれば実際にロングクランキングが発生した又はロングクランキングが発生しそうであると判定する。 In this embodiment, after detecting a situation where long cranking has occurred or is likely to occur, the electric component can be as close as possible by suppressing the output of the electric component or stopping the operation of the electric component. Do not reduce functionality.
In order to determine the situation where long cranking is occurring or likely to occur, the situation where the starter motor 90 is operating and boosting is used. Therefore, while the starter motor 90 is in operation, time is measured from the start of boosting, and it is determined that long cranking has actually occurred or long cranking is likely to occur if the time exceeds a predetermined time threshold. Alternatively, the operation time of the starter motor 90 is measured during boosting, and it is determined that long cranking has actually occurred or long cranking is likely to occur if it exceeds a predetermined time threshold.
　図２は、本発明の第１の実施形態に係る電装部品制御装置の手順例を示すフロー図である。
　アイドリングストップ制御によるエンジン停止状態から、エンジン再始動させる状況で本手順の処理は実行される。 FIG. 2 is a flow chart showing an example of the procedure of the electrical component control apparatus according to the first embodiment of the present invention.
The processing of this procedure is executed in a state where the engine is restarted from the engine stop state by the idling stop control.
　ステップＳ１１０で、昇圧制御ユニット１２０は昇圧回路２０をオフからオンにする。また昇圧制御ユニット１２０は、バイパス回路５０をオンからオフにする。これにより、昇圧回路２０からの電圧が電流検出回路３０とオーディオミュートスイッチ７０を経由してオーディオ機器８０に供給される。
　ステップＳ１２０で、アイドリングストップ制御ユニット１１０はスタータモータ９０を作動させ、エンジンを再始動させる。
　電装部品出力制御ユニット１３０は、図示しないタイマーを０から作動させる。 In step S110, the boost control unit 120 turns on the boost circuit 20 from off. The boost control unit 120 also turns the bypass circuit 50 off. Thus, the voltage from the booster circuit 20 is supplied to the audio device 80 via the current detection circuit 30 and the audio mute switch 70.
In step S120, the idling stop control unit 110 operates the starter motor 90 to restart the engine.
The electrical component output control unit 130 operates a timer (not shown) from zero.
　ステップＳ１３０で、電装部品出力制御ユニット１３０はタイマーの時間ｔｍと時間閾値Ｔｔｉｍｅとを比較する。時間閾値Ｔｔｉｍｅは、たとえば１秒とする。昇圧開始からの時間ｔｍが時間閾値Ｔｔｉｍｅ未満であればステップＳ１４０へ移行する。昇圧開始からの時間ｔｍが時間閾値Ｔｔｉｍｅ以上となればステップＳ１５０へ移行する。
　ステップＳ１４０で、電装部品出力制御ユニット１３０はエンジン始動が完了したか判定する。エンジンが始動すれば、ミュートせずにそのまま終了する。 In step S130, the electrical component output control unit 130 compares the time tm of the timer with the time threshold Ttime. The time threshold Ttime is, for example, one second. If the time tm from the start of boosting is less than the time threshold Ttime, the process proceeds to step S140. If the time tm from the start of boosting becomes equal to or longer than the time threshold Ttime, the process proceeds to step S150.
In step S140, the electrical component output control unit 130 determines whether the engine start has been completed. When the engine starts, it ends without muting.
　ステップＳ１５０で、電装部品出力制御ユニット１３０はオーディオミュートスイッチ７０へオーディオをミュートするミュート信号を出力する。オーディオミュートスイッチ７０はミュート信号により、昇圧回路２０からの電圧をオフにする。これによりオーディオ機器８０はミュート状態となり、オーディオ機器８０の作動は停止される。 In step S150, the electrical component output control unit 130 outputs a mute signal for muting the audio to the audio mute switch 70. The audio mute switch 70 turns off the voltage from the booster circuit 20 by the mute signal. As a result, the audio device 80 is muted, and the operation of the audio device 80 is stopped.
　実際にエンジン再始動が終了して車両の走行が開始すれば、昇圧制御ユニット１２０は昇圧回路２０をオンからオフにし、バイパス回路５０をオフからオンに戻すことで昇圧制御を終了させる。また電装部品出力制御ユニット１３０は、タイマーをリセットし、ミュート状態であればオーディオミュートスイッチ７０へミュートを解除する信号を出力して、オーディオ機器８０を通常状態へ戻す。 When engine restart is actually completed and vehicle travel starts, the boost control unit 120 turns the boost circuit 20 off from on and turns the bypass circuit 50 back on from off to end boost control. Further, the electric component output control unit 130 resets the timer, and outputs a signal for releasing the mute to the audio mute switch 70 if it is in the mute state, thereby returning the audio device 80 to the normal state.
　なお、クランキング時間が第２の所定時間を超えると、強制的にクランキングを停止させる制御が作動される。第２の所定時間は、たとえば５秒とする。オーディオミュートのための時間閾値Ｔｔｉｍｅは、通常の始動にかかるクランキング時間よりも長く、かつ第２の所定時間よりも短く設定する。 When the cranking time exceeds the second predetermined time, control for forcibly stopping the cranking is operated. The second predetermined time is, for example, 5 seconds. The time threshold Ttime for audio mute is set to be longer than the cranking time required for normal startup and shorter than the second predetermined time.
　また、タイマー時間ｔｍの計測は、スタータモータ９０が作動している状態での昇圧制御ユニット１２０の昇圧時間であっても、昇圧制御ユニット１２０が作動している状態でのスタータモータ９０の作動時間であってもよいので、ステップＳ１１０の昇圧制御ユニット１２０の処理と、ステップ１２０のアイドリングストップ制御ユニット１１０の処理の順序を入れ替えてもよい。 Further, the measurement of timer time tm is the operation time of starter motor 90 in the state where boost control unit 120 is operating even if the pressure increase time of boost control unit 120 is in the state where starter motor 90 is operating. Since the process may be performed in step S110, the order of the process of step-up control unit 120 and the process of idling stop control unit 110 may be reversed.
　次に制御例についてタイミングチャートを用いて詳細に説明する。
　図３は、本発明の第１の実施形態に係る電装部品制御装置の動作例を示すタイミングチャートである。矢印ｔの方向に時間が進行するものとする。 Next, a control example will be described in detail using a timing chart.
FIG. 3 is a timing chart showing an operation example of the electrical component control apparatus according to the first embodiment of the present invention. It is assumed that time advances in the direction of arrow t.
　車両の走行状態が「走行」から説明する。アイドリングストップ制御ユニット１１０はエンジンの停止条件を監視する。昇圧制御ユニット１２０はバイパス回路５０をオンにして昇圧回路２０をオフにする。電装部品出力制御ユニット１３０はオーディオミュートスイッチ７０を通常状態であるオンになるように出力する。オーディオミュートスイッチ７０は、導通状態となり、オーディオ機器８０にはバイパス回路５０を経由したバッテリ１０からの電圧が供給される。その結果、オーディオ機器８０は通常状態となる。 The traveling state of the vehicle will be described from "traveling". The idling stop control unit 110 monitors engine stop conditions. The boost control unit 120 turns on the bypass circuit 50 and turns off the boost circuit 20. The electrical component output control unit 130 outputs the audio mute switch 70 to be on, which is a normal state. The audio mute switch 70 is turned on, and the audio device 80 is supplied with the voltage from the battery 10 via the bypass circuit 50. As a result, the audio device 80 is in the normal state.
　タイミングＴ１で、アイドリングストップ制御ユニット１１０はエンジンの自動停止条件が成立したことを判定してエンジンを自動停止させる。車両の走行状態は、走行からアイドリングストップに移行する。アイドリングストップ制御ユニット１１０は、その後エンジン再始動条件を監視する。 At timing T1, the idling stop control unit 110 determines that the automatic stop condition of the engine is satisfied and automatically stops the engine. The traveling state of the vehicle shifts from traveling to idling stop. The idling stop control unit 110 then monitors the engine restart condition.
　タイミングＴ２で、エンジン再始動条件が成立すると、アイドリングストップ制御ユニット１１０は、スタータモータ９０を作動させて、エンジンの再始動を開始する。昇圧制御ユニット１２０は、バイパス回路５０をオフにし、昇圧回路２０をオンにして昇圧を開始する。オーディオ機器８０には昇圧回路２０からの電圧がオーディオミュートスイッチ７０を介して供給される。オーディオ機器８０に供給される電圧は、昇圧を開始した直後は昇圧が間に合わず、一時的に下がることがあるが、オーディオ機器８０の作動に影響がない程度であり、すぐに所定の電圧に戻る。またタイミングＴ２から、電装部品出力制御ユニット１３０は、昇圧時間ｔｍをタイマーで計測する。
　なお、アイドリングストップ制御ユニット１１０と昇圧制御ユニット１２０とは、それぞれ所定の遅延時間（待ち時間）の後に作動を開始させてもよい。 When the engine restart condition is satisfied at timing T2, the idling stop control unit 110 operates the starter motor 90 to start engine restart. The boost control unit 120 turns off the bypass circuit 50 and turns on the boost circuit 20 to start boosting. The voltage from the booster circuit 20 is supplied to the audio device 80 through the audio mute switch 70. Although the voltage supplied to the audio device 80 may not be boosted in time immediately after the start of boosting and may temporarily drop, the voltage does not affect the operation of the audio device 80 and returns to the predetermined voltage immediately. . Further, from timing T2, the electrical component output control unit 130 measures the boosting time tm with a timer.
The idling stop control unit 110 and the boost control unit 120 may each start operation after a predetermined delay time (waiting time).
　電装部品出力制御ユニット１３０は、昇圧時間ｔｍを所定の時間閾値Ｔｔｉｍｅと比較する。
　ロングクランキングが発生しない正常状態では、昇圧時間ｔｍが時間閾値Ｔｔｉｍｅに到達する前に実際にエンジンが再起動して通常状態となり、車両が走行を開始するが、そうならない場合に次のように制御される。 The electrical component output control unit 130 compares the boosting time tm with a predetermined time threshold Ttime.
Under normal conditions where long cranking does not occur, the engine actually restarts and becomes normal before the boost time tm reaches the time threshold Ttime, and the vehicle starts traveling, but if this is not the case It is controlled.
　昇圧時間ｔｍが時間閾値Ｔｔｉｍｅ以上となったタイミングＴ３で、電装部品出力制御ユニット１３０は実際にロングクランキングが発生した又はロングクランキングが発生する可能性があると判定する。電装部品出力制御ユニット１３０は、所定の遅延後のタイミングＴ４で、オーディオ機器８０がミュート状態となるようにオーディオミュートスイッチ７０へミュート信号を出力する。オーディオミュートスイッチ７０はオフとなり、オーディオ機器８０には昇圧回路２０からの電圧が供給されない。その結果、オーディオ機器８０はミュート状態となる。 At timing T3 when the boosting time tm becomes equal to or longer than the time threshold value Ttime, the electrical component output control unit 130 determines that long cranking may actually occur or long cranking may occur. The electrical component output control unit 130 outputs a mute signal to the audio mute switch 70 so that the audio device 80 is in the mute state at timing T4 after the predetermined delay. The audio mute switch 70 is turned off, and the audio device 80 is not supplied with the voltage from the booster circuit 20. As a result, the audio device 80 is muted.
　その後、タイミングＴ５で、実際にエンジンが立ち上がり、車両の走行状態は、アイドリングストップから走行へ移行する。またタイミングＴ５で、昇圧制御ユニット１２０は、バイパス回路５０をオフからオンにし、昇圧回路２０をオンからオフに制御する。
　タイミングＴ５の後のタイミングＴ６で、電装部品出力制御ユニット１３０は、オーディオミュートスイッチ７０へミュート信号を解除する信号をオーディオミュートスイッチ７０へ出力する。これにより、オーディオ機器８０は通常状態に復帰する。 Thereafter, at timing T5, the engine actually starts up, and the traveling state of the vehicle shifts from idling stop to traveling. Further, at timing T5, the boost control unit 120 turns the bypass circuit 50 from off to on, and controls the boost circuit 20 from on to off.
At timing T6 after timing T5, the electrical component output control unit 130 outputs a signal for releasing the mute signal to the audio mute switch 70 to the audio mute switch 70. Thereby, the audio device 80 returns to the normal state.
　以上のように、スタータモータ９０を作動させ、昇圧した場合に、直ちにオーディオ機器８０の出力を制限するのではなく、実際にロングクランキングが発生したと判断される又はロングクランキングが発生しそうになる所定時間まではオーディオをミュートしない。 As described above, when the starter motor 90 is operated and boosted, it is determined that long cranking has actually occurred or long cranking is likely to occur instead of immediately limiting the output of the audio device 80. Not mute the audio until a predetermined time
　なお、オーディオをミュートする代わりにオーディオの音量を低下させるようにしてもよい。この場合は、電装部品出力制御ユニット１３０は、オーディオミュートスイッチ７０による電圧のミュートではなく、オーディオ機器８０へ直接音量を低下する信号を出力することでオーディオ機器８０の出力を抑制する。
　また、オーディオ機器８０にはディスプレイを備え、設定により車両の後方を撮影するカメラの画像を表示する機能がある車両がある。本実施例では、昇圧により直ちにディスプレイを用いる機能が制限される、というような機能制限の問題は、解消される。
　また、オーディオ機器８０の代わりに、ディスプレイ機器などの他の電装部品を備えてもよい。この場合は電装部品出力制御ユニット１３０が、他の電装部品の出力を抑制または動作停止をする制御をする。 The audio volume may be reduced instead of muting the audio. In this case, the electrical component output control unit 130 suppresses the output of the audio device 80 by outputting a signal for directly reducing the volume to the audio device 80 instead of muting the voltage by the audio mute switch 70.
In addition, the audio device 80 includes a display, and there is a vehicle having a function of displaying an image of a camera for photographing the rear of the vehicle by setting. In the present embodiment, the problem of functional limitation, such as the function of using the display being immediately limited by boosting, is solved.
Also, instead of the audio device 80, other electrical components such as a display device may be provided. In this case, the electrical component output control unit 130 performs control to suppress or stop the output of other electrical components.
　また、車両にはエンジンを始動させるイグニッションがあるが、オーディオミュートスイッチ７０は、イグニッションのＡＣＣスイッチがオフであれば導通させないようにしてもよい。この場合は、処理装置６０とオーディオミュートスイッチ７０との間に、オーディオミュートスイッチ制御回路を設置する。オーディオミュートスイッチ制御回路は、イグニッションのＡＣＣスイッチがオフであればオーディオミュートスイッチ７０が必ずオフになるような制御信号を出力させる。これにより、ＡＣＣスイッチと連動したオーディオ機器８０の動作が可能になる。 Although the vehicle has an ignition for starting the engine, the audio mute switch 70 may not be turned on if the ACC switch of the ignition is off. In this case, an audio mute switch control circuit is provided between the processing device 60 and the audio mute switch 70. The audio mute switch control circuit outputs a control signal such that the audio mute switch 70 is always turned off if the ACC switch of the ignition is off. This enables the operation of the audio device 80 in conjunction with the ACC switch.
≪第２実施形態≫
　第２実施形態では、電装部品の出力を抑制する又は電装部品の作動を停止する条件をさらに追加する。
　車両の商品性という観点からは、なるべく電装部品の出力を抑制する又は電装部品の作動を停止する、ということがないことが望ましい。電圧低下する１つの原因は、オーディオ機器８０の出力が大きくなった場合などに、昇圧回路２０が出力する電流が多量に流れる過負荷状態になることによる。
　第２実施形態では、昇圧回路２０が出力する電流が所定の電流閾値Ｔｃｕｒｒ以上となる電流条件を、電装部品の出力を抑制する又は電装部品の作動を停止する条件に加える。 Second Embodiment
In the second embodiment, a condition for suppressing the output of the electric component or stopping the operation of the electric component is further added.
From the viewpoint of the marketability of the vehicle, it is desirable not to suppress the output of the electrical component or to stop the operation of the electrical component as much as possible. One reason for the voltage drop is that, for example, when the output of the audio device 80 is increased, a large amount of current output from the booster circuit 20 flows, resulting in an overload state.
In the second embodiment, a current condition in which the current output from the booster circuit 20 is equal to or more than a predetermined current threshold Tcurr is added to the condition for suppressing the output of the electrical component or for stopping the operation of the electrical component.
　また、昇圧回路２０などで使用される基板には、正常な動作が保証される基板保証温度Ｔｔｅｍｐ１がある。基板の温度が基板保証温度Ｔｔｅｍｐ１以上とならないようにする必要がある。第２実施形態では、基板保証温度Ｔｔｅｍｐ１より低い温度であるオーディオカット判断温度という温度閾値Ｔｔｅｍｐ２を設定する。たとえば、基板保証温度Ｔｔｅｍｐ１が１３０℃であれば温度閾値Ｔｔｅｍｐ２は１１０℃とする。
　昇圧回路２０付近の温度が温度閾値Ｔｔｅｍｐ２以上となる温度条件を、電装部品の出力を抑制する又は電装部品の作動を停止する条件に加える。 Further, a substrate used in the booster circuit 20 or the like has a substrate guaranteed temperature Ttemp1 at which normal operation is guaranteed. The temperature of the substrate needs to be not higher than the substrate guarantee temperature Ttemp1. In the second embodiment, a temperature threshold Ttemp2 that is an audio cut determination temperature which is a temperature lower than the substrate guarantee temperature Ttemp1 is set. For example, if the substrate guarantee temperature Ttemp1 is 130 ° C., the temperature threshold Ttemp2 is 110 ° C.
A temperature condition in which the temperature in the vicinity of the booster circuit 20 becomes equal to or higher than the temperature threshold Ttemp2 is added to the condition for suppressing the output of the electric component or stopping the operation of the electric component.
　例としてオーディオをミュートした場合の温度に対する効果を説明する。
　図４は、基板保証温度まで温度上昇する前にオーディオをミュートした場合の効果を示すタイミングチャートである。
　基板の温度ｔｅは、昇圧回路２０またはその付近で検出することが望ましいので、温度センサ４０から取得する。 The effect on temperature when muting the audio will be described as an example.
FIG. 4 is a timing chart showing the effect of muting the audio before the temperature rises to the board guaranteed temperature.
The substrate temperature te is preferably obtained from the temperature sensor 40 because it is desirable to detect the temperature te at or near the booster circuit 20.
　温度ｔｅが上昇し、タイミングＴ１１で温度閾値Ｔｔｅｍｐ２以上となった場合からオーディオをミュート制御する。タイミングＴ１１からオーディオ機器８０での電力消費が抑制され、発熱が削減することにより、図４の点線Ｌ１で示すミュート制御しない場合と比較して、温度ｔｅの上昇速度は矢印Ｄ１の方向に抑圧されて遅くなり、実線Ｌ２で示すように推移する。そのため、温度ｔｅは基板保証温度Ｔｔｅｍｐ１まで上昇しない。 The audio is mute-controlled from the case where the temperature te rises and reaches the temperature threshold Ttemp2 or more at the timing T11. The power consumption in the audio device 80 is suppressed from the timing T11, and the heat generation is reduced, whereby the rising speed of the temperature te is suppressed in the direction of the arrow D1 as compared to the case where the mute control indicated by the dotted line L1 in FIG. And becomes slower as shown by the solid line L2. Therefore, the temperature te does not rise to the substrate guarantee temperature Ttemp1.
　次に制御手順を説明する。
　図５は、本発明の第２の実施形態に係る電装部品制御装置の手順例を示すフロー図である。
　アイドリングストップ制御ユニット１１０によるエンジン停止状態から、エンジン再始動させる状況で本手順の処理は実行される。スタータモータ９０を作動させた状態から説明する。 Next, the control procedure will be described.
FIG. 5 is a flow chart showing an example of the procedure of the electrical component control apparatus according to the second embodiment of the present invention.
The processing of this procedure is executed in a situation where the engine is restarted from the engine stop state by the idling stop control unit 110. The operation of the starter motor 90 will be described.
　ステップＳ２１０で、昇圧制御ユニット１２０は電圧を昇圧させる処理をする。
　次にステップＳ２２０で，アイドリングストップ制御ユニット１１０はスタータモータ９０を作動させ、エンジンを再始動させる。
　ステップＳ２１０、Ｓ２２０の処理は、それぞれ第１の実施形態で説明したステップＳ１１０、Ｓ１２０の処理と同様である。電装部品出力制御ユニット１３０は、タイマーを０から作動させる。
　次にステップＳ２３０へ移行する。 In step S210, the boost control unit 120 performs a process of boosting the voltage.
Next, in step S220, the idling stop control unit 110 operates the starter motor 90 to restart the engine.
The processes of steps S210 and S220 are the same as the processes of steps S110 and S120 described in the first embodiment, respectively. The electrical component output control unit 130 operates the timer from zero.
Next, the process proceeds to step S230.
　ステップＳ２３０で、温度条件を判定する。温度センサ４０からの温度ｔｅと温度閾値Ｔｔｅｍｐ２とを比較し、温度ｔｅが温度閾値Ｔｔｅｍｐ２以上と判定すれば過熱状態とあると判断し、ステップＳ２４０へ移行する。温度ｔｅが温度閾値Ｔｔｅｍｐ２以上でなければ終了する。 In step S230, a temperature condition is determined. The temperature te from the temperature sensor 40 and the temperature threshold Ttemp2 are compared, and if it is determined that the temperature te is equal to or higher than the temperature threshold Ttemp2, it is determined that an overheated state exists, and the process proceeds to step S240. If the temperature te is not higher than the temperature threshold Ttemp2, the process ends.
　ステップＳ２４０で、時間条件を判定する。第１の実施形態で説明したように、昇圧時間ｔｍと時間閾値Ｔｔｉｍｅとを比較し、昇圧時間ｔｍが時間閾値Ｔｔｉｍｅ以上と判定すれば実際にロングクランキングが発生した又はロングクランキングが発生する可能性が高いと判断し、ステップＳ２６０へ移行する。昇圧時間ｔｍが時間閾値Ｔｔｉｍｅ以上でなければ、ステップＳ２５０へ移行する。
　ステップＳ２５０で、電装部品出力制御ユニット１３０はエンジン始動が完了したか判定する。エンジンが始動すれば、ミュートせずにそのまま終了する。 At step S240, a time condition is determined. As described in the first embodiment, when the boosting time tm and the time threshold Ttime are compared, and it is determined that the boosting time tm is the time threshold Ttime or more, long cranking actually occurs or long cranking occurs. It is determined that the possibility is high, and the process proceeds to step S260. If the boosting time tm is not longer than the time threshold Ttime, the process proceeds to step S250.
In step S250, the electrical component output control unit 130 determines whether the engine start has been completed. When the engine starts, it ends without muting.
　ステップＳ２６０で、電流条件を判定する。電流検出回路３０からの電流値と電流閾値Ｔｃｕｒｒとを比較し、電流値が電流閾値Ｔｃｕｒｒ以上と判定すれば過負荷状態とあると判断し、ステップＳ２７０へ移行する。電流閾値Ｔｃｕｒｒは、たとえば５Ａとする。電流値は瞬間値であっても、短い時間の移動平均でもあってもよい。
　また、電流検出は、電流検出回路３０の代わりにオーディオ機器８０の負荷電流から検出してもよい。この場合、処理装置６０は負荷電流値をオーディオ機器８０から取得する。
　電流値が電流閾値Ｔｃｕｒｒ以上でなければ終了する。 In step S260, the current condition is determined. The current value from the current detection circuit 30 is compared with the current threshold value Tcurr, and if it is determined that the current value is equal to or higher than the current threshold value Tcurr, it is determined that an overload state exists, and the process proceeds to step S270. The current threshold Tcurr is, for example, 5A. The current value may be an instantaneous value or a moving average of a short time.
Also, the current detection may be detected from the load current of the audio device 80 instead of the current detection circuit 30. In this case, the processing device 60 acquires the load current value from the audio device 80.
If the current value is not greater than the current threshold Tcurr, the process ends.
　ステップＳ２７０で、電装部品出力制御ユニット１３０は、オーディオ機器８０をミュートする処理をする。すなわち電装部品出力制御ユニット１３０は、オーディオミュートスイッチ７０へオーディオ機器８０をミュートするミュート信号を出力する。オーディオミュートスイッチ７０はミュート信号により、昇圧回路２０からの電圧をオフにする。これによりオーディオ機器８０はミュートされる。 In step S270, the electrical component output control unit 130 mutes the audio device 80. That is, the electrical component output control unit 130 outputs a mute signal for muting the audio device 80 to the audio mute switch 70. The audio mute switch 70 turns off the voltage from the booster circuit 20 by the mute signal. Thus, the audio device 80 is muted.
　以上の制御により、過負荷状態や過熱状態でなければオーディオ機器８０をミュートしない。
　第２の実施形態では、オーディオ機器８０のミュートが、時間条件に加えて過電流と過熱という条件に限定されるため、市場でのオーディオ機器８０のミュートの発生頻度はさらに低くなる。
　また、過電流や過熱により内部故障に至らないことが保証される。
　このように、オーディオミュートによる車両の商品性の低下は防止される。 As a result of the above control, the audio device 80 is not muted unless it is overloaded or overheated.
In the second embodiment, since the muting of the audio device 80 is limited to the conditions of over current and overheating in addition to the time condition, the frequency of occurrence of the muting of the audio device 80 in the market is further reduced.
In addition, it is guaranteed that the internal failure does not occur due to over current or overheating.
In this way, the deterioration of the vehicle's merchandiseability due to the audio mute is prevented.
