Description

本発明は、発電機が発電した電力により充電されるバッテリが放電した電力、及び発電機が発電した電力による負荷への通電、特にデアイサ（deicer）、デフォッガ(defogger)等のヒータ系負荷への通電を制御する車両用電源制御装置に関するものである。   The present invention relates to the power discharged from the battery charged by the power generated by the generator and the energization of the load by the power generated by the generator, particularly to the heater system load such as a deicer or defogger. The present invention relates to a vehicle power supply control device that controls energization.

近年、車両に搭載される電装品の数が、安全性、利便性、快適性、商品力の面から増加の一途をたどっており、車両全体の消費電力量が増加している。一方、燃料価格の高騰及び環境対策の為、車両の燃費向上への要求も高まっている。燃費向上の一つの手段として、オルタネータ（車載発電機、交流発電機）の発電量を抑制することになる消費電力量の削減も有効である。また、電源であるバッテリの容量が低下した場合にも、その対策として消費電力量を削減することは当然有効である。   In recent years, the number of electrical components mounted on a vehicle has been steadily increasing in terms of safety, convenience, comfort, and product power, and the power consumption of the entire vehicle is increasing. On the other hand, demands for improving the fuel efficiency of vehicles are increasing due to soaring fuel prices and environmental measures. As one means for improving fuel efficiency, it is also effective to reduce the amount of power consumption that suppresses the amount of power generated by an alternator (vehicle generator, AC generator). Moreover, even when the capacity of the battery as the power source is reduced, it is naturally effective to reduce the power consumption as a countermeasure.

特許文献１には、車両に搭載された大電気負荷の起動を把握し、車載発電機の発電能力を超過して給電不足が発生する可能性がある場合には、大電気負荷を起動させない負荷制御装置が開示されている。   Patent Document 1 describes the start of a large electrical load mounted on a vehicle, and when there is a possibility that insufficient power supply occurs due to exceeding the power generation capacity of the on-vehicle generator, a load that does not start the large electrical load. A control device is disclosed.

消費電力量を削減する場合、負荷への通電を遮断するのも一つの対策であるが、通電を遮断することにより、ユーザの利便性が低下するという問題がある。その為、ヒータ系負荷等において、バッテリの出力電圧値に応じて、通電量をＰＷＭ制御により増減制御することが提案された。これは、バッテリの出力電圧値が高いときは、通電量（デューティ比）を小さく設定することにより、消費電力の削減を図る。また、バッテリの出力電圧値が低いときは、通電量を大きく設定することにより、ヒータ機能を確保する。   When reducing the amount of power consumption, it is one measure to cut off the power supply to the load, but there is a problem that the convenience for the user is reduced by cutting off the power supply. Therefore, it has been proposed to increase or decrease the energization amount by PWM control according to the output voltage value of the battery in the heater system load or the like. This is intended to reduce power consumption by setting the energization amount (duty ratio) small when the output voltage value of the battery is high. Further, when the output voltage value of the battery is low, the heater function is ensured by setting the energization amount large.

しかし、このように通電量をＰＷＭ制御する場合、消費電力を削減することについては有効であるが、バッテリの容量が低下しているときに、負荷への通電量を大きく設定して、バッテリへの負担をより大きくしてしまうという問題がある。
本発明は、上述したような事情に鑑みてなされたものであり、バッテリ容量の低下を回避しながら、負荷による消費電力を削減することが可能な車両用電源制御装置を提供することを目的とする。 However, when the energization amount is PWM controlled in this way, it is effective to reduce the power consumption. However, when the battery capacity is low, the energization amount to the load is set to a large value to the battery. There is a problem of increasing the burden of.
The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a vehicle power supply control device capable of reducing power consumption due to a load while avoiding a decrease in battery capacity. To do.

以下に、本発明をその実施の形態を示す図面に基づき説明する。
図１は、本発明に係る車両用電源制御装置の実施の形態の要部構成を示すブロック図である。
この車両用電源制御装置は、マイクロコンピュータを備えた制御部３が、半導体スイッチング素子７により、負荷であるデアイサ８への通電をオン／オフする。
デアイサ８の電源は、車両に搭載されたバッテリＢ、及びバッテリＢを充電するオルタネータ（発電機、交流発電機）１から与えられる。 Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof.
FIG. 1 is a block diagram showing a main configuration of an embodiment of a vehicle power supply control device according to the present invention.
In this vehicular power supply control device, a control unit 3 having a microcomputer turns on / off energization to a deaiser 8 as a load by means of a semiconductor switching element 7.
The power supply of the deaiser 8 is supplied from a battery B mounted on the vehicle and an alternator (generator, alternator) 1 that charges the battery B.

バッテリＢの出力電圧値は、制御部３が内蔵する電圧検出手段９により検出される。また、バッテリＢの充放電電流値が電流検出器（充電電流検出器）６により検出され、制御部３に与えられる。制御部３には、また、イグニッションスイッチ２及びデアイサ８のスイッチＳＷの各オン／オフ信号が与えられる。制御部３は、タイマ５を内蔵している。
制御部３が内蔵するメモリ（記憶手段）４には、図３に示すような、バッテリＢへの充電電流値、及びデアイサ８への電力を半導体スイッチング素子７によりＰＷＭ制御する際のデューティ比（通電量）の対応関係がテーブルとして記憶されている。尚、この対応関係は、数式として記憶されていても良い。 The output voltage value of the battery B is detected by voltage detection means 9 built in the control unit 3. Further, the charge / discharge current value of the battery B is detected by a current detector (charge current detector) 6 and given to the control unit 3. The control unit 3 is also given ON / OFF signals of the ignition switch 2 and the switch SW of the deaiser 8. The control unit 3 includes a timer 5.
The memory (storage means) 4 built in the control unit 3 has a duty ratio (when the PWM control is performed by the semiconductor switching element 7 for the charging current value to the battery B and the power to the deaiser 8 as shown in FIG. The correspondence relationship of the energization amount is stored as a table. This correspondence relationship may be stored as a mathematical expression.

バッテリＢへの充電電流値、及びデアイサ８への電力のデューティ比の対応関係は、充電電流値が所定電流値Ｉ１以上である場合について定めてある。例えば、所定電流値Ｉ１から電流値Ｉ２（＞Ｉ１）迄は、電流値の増加に応じて、デューティ比は１００％から低下して行き、充電電流値が電流値Ｉ２以上では、デューティ比は一定（例えば５０％）となる。   The correspondence relationship between the charging current value to the battery B and the duty ratio of the power to the deaiser 8 is determined when the charging current value is equal to or greater than the predetermined current value I1. For example, from a predetermined current value I1 to a current value I2 (> I1), the duty ratio decreases from 100% as the current value increases. When the charging current value is equal to or greater than the current value I2, the duty ratio is constant. (For example, 50%).

充電電流値が所定電流値Ｉ１より小さい場合、デューティ比は、従来のように、バッテリＢの出力電圧値Ｖに基づき、例えば、(１２／Ｖ)2 ×１００（％）により算出する。
これにより、充電電流値が大きいとき、つまり、バッテリ容量が低いときは、バッテリを充電しながら、ある程度デアイサ８のヒータ機能を利用することができると共に、デアイサ８による消費電力を削減することができる。 When the charging current value is smaller than the predetermined current value I1, the duty ratio is calculated by, for example, (12 / V) 2 × 100 (%) based on the output voltage value V of the battery B as in the conventional case.
Thereby, when the charging current value is large, that is, when the battery capacity is low, the heater function of the deaiser 8 can be used to some extent while charging the battery, and the power consumption by the deaiser 8 can be reduced. .

以下に、このような構成のヒータの制御装置の動作の例を、それを示す図２のフローチャートを参照しながら説明する。
制御部３は、先ず、イグニッションスイッチ２がオンになっているか否かを判定し（Ｓ１）、オンになっていれば、デアイサ８のスイッチＳＷがオンになっているか否かを判定する（Ｓ３）。
制御部３は、デアイサ８のスイッチＳＷがオンになっていれば（Ｓ３）、半導体スイッチング素子７をＰＷＭ制御する為のデューティ比が設定されているか否かを判定する（Ｓ５）。デューティ比が設定されておらず、デューティ比を記憶していなければ、電流検出器６が検出した充電電流値を読込む（Ｓ７）。 Hereinafter, an example of the operation of the heater control apparatus having the above configuration will be described with reference to the flowchart of FIG.
First, the controller 3 determines whether or not the ignition switch 2 is turned on (S1). If the ignition switch 2 is turned on, the controller 3 determines whether or not the switch SW of the deaiser 8 is turned on (S3). ).
If the switch SW of the deaiser 8 is turned on (S3), the controller 3 determines whether or not a duty ratio for PWM control of the semiconductor switching element 7 is set (S5). If the duty ratio is not set and the duty ratio is not stored, the charging current value detected by the current detector 6 is read (S7).

制御部３は、充電電流値を読込むと（Ｓ７）、読込んだ充電電流値が、図３に示す所定電流値Ｉ１以上であるか否かを判定する（Ｓ９）。充電電流値が、所定電流値Ｉ１以上でなければ、電圧検出手段９が検出したバッテリＢの出力電圧値Ｖを読込む（Ｓ１１）。次いで、読込んだバッテリＢの出力電圧値Ｖに基づき、例えば、(１２／Ｖ)2 ×１００（％）によりデューティ比を算出し設定する（Ｓ１３）。
制御部３は、次に、設定したデューティ比（Ｓ１３）で半導体スイッチング素子７をＰＷＭ制御することにより、デアイサ８への通電を開始し（Ｓ１５）、タイマ５に計時を開始させる（Ｓ１７）。 When the control unit 3 reads the charging current value (S7), the control unit 3 determines whether or not the read charging current value is equal to or greater than the predetermined current value I1 shown in FIG. 3 (S9). If the charging current value is not equal to or greater than the predetermined current value I1, the output voltage value V of the battery B detected by the voltage detecting means 9 is read (S11). Next, based on the read output voltage value V of the battery B, for example, the duty ratio is calculated and set by (12 / V) 2 × 100 (%) (S13).
Next, the controller 3 starts energization to the deaiser 8 by performing PWM control of the semiconductor switching element 7 with the set duty ratio (S13), and causes the timer 5 to start measuring time (S17).

制御部３は、次に、タイマ５が計時した時間が、予め設定してある通電時間以上であるか否かを判定し（Ｓ１９）、設定してある通電時間以上でなければ、イグニッションスイッチ２がオンになっているか否かを判定する（Ｓ１）。
制御部３は、タイマ５が計時した時間が、設定してある通電時間以上であれば（Ｓ１９）、半導体スイッチング素子７でデアイサ８への通電を停止し（Ｓ２５）、タイマ５をリセットする（Ｓ２７）。次いで、イグニッションスイッチ２がオンになっているか否かを判定する（Ｓ１）。 Next, the controller 3 determines whether or not the time counted by the timer 5 is equal to or longer than a preset energization time (S19). If the time is not equal to or greater than the preset energization time, the ignition switch 2 is determined. It is determined whether or not is turned on (S1).
If the time counted by the timer 5 is equal to or longer than the set energization time (S19), the controller 3 stops energization to the deaiser 8 by the semiconductor switching element 7 (S25) and resets the timer 5 ( S27). Next, it is determined whether or not the ignition switch 2 is turned on (S1).

制御部３は、読込んだ充電電流値が所定電流値Ｉ１以上であれば（Ｓ９）、メモリ４に記憶してあるテーブルを参照して、読込んだ充電電流値に対応するデューティ比を読出して設定する（Ｓ２３）。次いで、設定したデューティ比で半導体スイッチング素子７をＰＷＭ制御することにより、デアイサ８への通電を開始し（Ｓ１５）、タイマ５に計時を開始させる（Ｓ１７）。
制御部３は、デューティ比が設定されていれば（Ｓ５）、タイマ５が計時した時間が、設定してある通電時間以上であるか否かを判定する（Ｓ１９）。 If the read charging current value is equal to or greater than the predetermined current value I1 (S9), the control unit 3 refers to the table stored in the memory 4 and reads the duty ratio corresponding to the read charging current value. (S23). Next, PWM control of the semiconductor switching element 7 with the set duty ratio starts energization to the deaiser 8 (S15), and the timer 5 starts measuring time (S17).
If the duty ratio is set (S5), the controller 3 determines whether the time counted by the timer 5 is equal to or longer than the set energization time (S19).

制御部３は、イグニッションスイッチ２がオンになっていなければ（Ｓ１）、又はデアイサ８のスイッチＳＷがオンになっていなければ（Ｓ３）、デアイサ８が通電中であるか否かを判定する（Ｓ２１）。デアイサ８が通電中でなければ、イグニッションスイッチ２がオンになっているか否かを判定する（Ｓ１）。
制御部３は、デアイサ８が通電中であれば（Ｓ２１）、デアイサ８への通電を停止し（Ｓ２５）、タイマ５をリセットした（Ｓ２７）後、イグニッションスイッチ２がオンになっているか否かを判定する（Ｓ１）。 If the ignition switch 2 is not turned on (S1) or if the switch SW of the deaiser 8 is not turned on (S3), the control unit 3 determines whether or not the deaiser 8 is energized ( S21). If the deaiser 8 is not energized, it is determined whether or not the ignition switch 2 is on (S1).
If the deaiser 8 is energized (S21), the controller 3 stops energizing the deaiser 8 (S25), resets the timer 5 (S27), and then determines whether or not the ignition switch 2 is turned on. Is determined (S1).
