Description

明 細 書 電気配線解析装置、 電気配線解析方法及び電気配線解析プログラムを記憶した記録媒体 <技術分野 >  Description Electrical wiring analyzer, electrical wiring analysis method, and storage medium storing electrical wiring analysis program <Technical field>
本発明は、 負荷部品、 電線、切替器及び電源を含む、 車両内の電気配線における、 負荷 電流、 電圧分布及び配線抵抗を計算して出力する電気配線解析装置、 その方法及びそのプ ログラムに関する。 <背景技術 >  The present invention relates to an electric wiring analysis apparatus that calculates and outputs a load current, a voltage distribution, and a wiring resistance in an electric wiring in a vehicle including a load component, an electric wire, a switch, and a power supply, and a method and a program thereof. <Background technology>
近年、 自動車の開発期間はますます短縮化される傾向にあり、 これにともない車載され る電装機器の開発期間も短縮化される傾向にある。このような現状から、負荷部品、電線、 切替器及び電源を含む電気配線をシミュレーションするための技術が多数提案されてい る。 例えば、 日本特許公開 2 0 0 2— 2 4 3 1 4号公報 （図 2、 図 4、 図 6及び図 7等） においては、 入力画面に複数の電気部品を選択配置し、 これら電気部品の名称及び形式を 入力して、 所望の電気配線の性能評価を行うシミュレーション装置が示されている。  In recent years, the development period of automobiles has tended to be further shortened, and accordingly, the development period of in-vehicle electrical equipment has also been shortened. Under such circumstances, many techniques for simulating electric wiring including load components, electric wires, switches, and power supplies have been proposed. For example, in Japanese Patent Publication No. 2002-224431 (FIG. 2, FIG. 4, FIG. 6, and FIG. 7, etc.), a plurality of electric components are selectively arranged on an input screen, and these electric components are arranged. A simulation device for inputting a name and a type and evaluating the performance of a desired electric wiring is shown.
上記関連技術によると、画面上で電気配線をシミュレーションできる点で大きな長所が あるが、 これを車両内の配線設計に適用するにあたり、 さらなる改善が求められている。 例えば、 車両電気部品の中には、 バルブ等のように、 電圧変動にともない電流変動する (又は電流変動にともない電圧変動する） というような、 動的特性を有する負荷部品が多 く存在する。 したがって、 このような負荷部品の特性も考慮した電気配線解析装置が求め られている。  According to the related technology described above, there is a great advantage in that electric wiring can be simulated on the screen, but further improvement is required when applying this to wiring design in vehicles. For example, there are many load components, such as valves, that have dynamic characteristics such as valves that change current (or change voltage with current), such as valves. Therefore, there is a need for an electrical wiring analyzer that also takes into account the characteristics of such load components.
また、 車両内には、 多種で比較的長い電線が多く配策される。 したがって、 電線の抵抗 値も無視できず、 このような電線の抵抗値も考慮した電気配線解析装置が求められている。 すなわち、 より正確な配線解析が可能な装置が求められている。  In addition, many types of relatively long wires are routed in vehicles. Therefore, the resistance of electric wires cannot be neglected, and there is a need for an electric wiring analysis device that takes such resistance values of electric wires into consideration. That is, there is a demand for a device capable of more accurate wiring analysis.
<発明の開示 > よって本発明は、 上述した現状に鑑み、 現実に即したより正確な電気配線の解析を可能 にする装置、 その方法及びそのプログラムを記録した記録媒体を提供することを課題とし ている。 <Disclosure of Invention> Accordingly, an object of the present invention is to provide an apparatus, a method thereof, and a recording medium on which a program thereof is recorded, which enables more accurate analysis of electric wiring based on the actual situation described above.

すなわち、 図 7に示すような、 電源 2 0、 ヒューズ 3 0〜3 3、 バルブ 4 1 ~ 4 3、 切 替器 5 1 ~ 5 3及びこれらを繋ぐ電線から構成される、 予め設計された電気配線に対して、 切替器 5 1〜5 3の切り替え状態が設定される。 すると、 計算に必要な経路が検索され、 この経路上にある電源 2 0、 ヒューズ 3 0〜3 3、 ノくルブ 4 1 ~ 4 3に関する各情報が読 み出され、 計算式がたてられる。詳しくは、 ヒューズ 3 0〜 3 3についてはそれらの抵抗 値が、 バルブ 4 1 ~ 4 3に関してはそれらの電圧電流特性が、 負荷部品情報として読み出 される。 ここでは、 ヒューズ 3 0〜3 3及びバルブ 4 1 ~ 4 3は、 計算式をたてる際に、 負荷部品として扱っている。 図 7において、 電源 20の電圧を VB、 ヒューズ 30〜33の負荷を R0~R3、 各経 路上の負荷電流を I 0~ I 3、 負荷を RO〜R 3に係る電圧を V 1 -V 3とすると、 まず、 キルヒホッフの第 1法則を利用して、 In other words, as shown in FIG. 7, a pre-designed electrical system composed of a power source 20, fuses 30 to 33, valves 41 to 43, switches 51 to 53, and electric wires connecting them. The switching state of the switches 51 to 53 is set for the wiring. Then, the route required for the calculation is searched, and information on the power supply 20, fuses 30 to 33, and knobs 41 to 43 on this route is read out, and a calculation formula is created. . More specifically, the resistance values of the fuses 30 to 33 and the voltage and current characteristics of the valves 41 to 43 are read as load component information. Here, the fuses 30 to 33 and the valves 41 to 43 are treated as load components when formulating the formula. In FIG. 7, the voltage of the power supply 20 is VB, the load of the fuses 30 to 33 is R0 to R3, the load current on each path is I0 to I3, and the load is RO1 to R3. Then, first, using Kirchhoff's first law,
1 0= 1 1 + I 2 + I 3  1 0 = 1 1 + I 2 + I 3
また、 キルヒホッフの第 2法則を利用して、  Using Kirchhoff's second law,
V 1 =VB- (R 0 * I 0 + R 1 * I 1 )  V 1 = VB- (R 0 * I 0 + R 1 * I 1)
V2 = VB— (R 0 * I 0 + R 2 * I 2)  V2 = VB— (R 0 * I 0 + R 2 * I 2)
V 3 =V B— (R 0 * I 0 + R 3 * I 3)  V 3 = V B— (R 0 * I 0 + R 3 * I 3)
また、 ノ《ルブ 4 1 ~43の電圧電流特性から、  Also, from the voltage-current characteristics of
I 1 =a 1 * V 1 + b 1 I 1 = a 1 * V 1 + b 1
I 2 = a 2 * V2 + b 2  I 2 = a 2 * V2 + b 2
I 3 = a 3 * V3 + b 3  I 3 = a 3 * V3 + b 3
という計算式をたてることができる。  Can be made.
このような計算式に基づき、 所望の負荷電流や電圧分布を計算することが可能である。 なお、 上記計算式では、 電線種及び電線長に依存して変化する電線抵抗値は考慮されてい ないが、 このような電線抵抗値も考慮して上記のような計算式をたてることが好ましい。 すなわち、 車両内には、 多種で比較的長い電線が配策されるので、 電線抵抗値も考慮して 上記のような計算式をたてることにより、 より現実的な電気配線の解析が可能となる。 このようなステップ S 301 a~ステップ S 30 1 Θからなる解析前処理が終了する と、 図 5 Αのステップ S 302に進んで、 全経路 （ここでは n経路とする） における負荷 電流が計算される。例えば、 上記のような計算式が解かれて、 検索された経路上の全負荷 電流がそれぞれ求められる。 そして、 ステップ S 303において、 上記計算された各負荷 電流が、 表示装置 1 3に既に表示されている配線図に合成され表示される。 この表示ィメ ージは、 後述の図 8にて示す負荷電流の表示に類似したものであり、選択された負荷部品 に対応づけてその値が表示される。  It is possible to calculate a desired load current and voltage distribution based on such a calculation formula. Although the above formula does not take into account the wire resistance that changes depending on the wire type and wire length, it is preferable to formulate the above formula taking such wire resistance into account. . In other words, since various types of relatively long wires are routed in the vehicle, more realistic analysis of electrical wiring can be performed by using the above formula in consideration of wire resistance. Become. When the pre-analysis processing consisting of step S301a to step S301 is completed, the process proceeds to step S302 in FIG. 5 and load currents in all paths (here, n paths) are calculated. You. For example, the above formula is solved, and the total load current on the searched path is obtained. Then, in step S303, the calculated load currents are combined with the wiring diagram already displayed on the display device 13 and displayed. This display image is similar to the display of the load current shown in FIG. 8 described later, and the value is displayed in association with the selected load component.
なお、 ステップ S 304において、 表示中の電気配線における任意の負荷部品に関する 負荷部品情報を表示させる場合には （ステップ S 304の Y) 、 ステップ S 305に進ん で、 負荷部品情報表示に係る処理が行われる。 すなわち、 この負荷部品情報表示では、 詳 しくは、 図 6 Bに示すように、 ステップ S 305 aにおいて表示中の電気配線における任  In step S304, if load component information relating to an arbitrary load component in the displayed electrical wiring is to be displayed (Y in step S304), the process proceeds to step S305, and the process related to the load component information display is performed. Done. That is, in the load component information display, as shown in FIG.
9 意の負荷部品が指定され、 ステップ S 3 0 5 bにおいてこの指定された負荷部品の負荷部 品情報が記憶装置 1 5から読み出され、 ステップ S 3 0 5 cにおいてこの読み出された負 荷部品情報が、 指定された負荷部品に対応づけて表示装置 1 3上に表示される。 負荷部品 の指定は、 例えば、 入力装置 1 2としてのマウスを利用した、 表示中の負荷部品に対する クリック操作が想定され、 表示される負荷部品情報は、 例えば、 図 3で示したような、 バ ルブの電圧電流特性が想定される。 9 A desired load component is specified, and in step S305b, the load component information of the specified load component is read from the storage device 15, and in step S305c, the read load is read. The component information is displayed on the display device 13 in association with the specified load component. The specification of the load component is assumed to be, for example, a click operation on the displayed load component using a mouse as the input device 12. The displayed load component information is, for example, a buffer as shown in FIG. 3. The lube voltage-current characteristics are assumed.
このように、 指定された負荷部品に対応する負荷部品情報が、 負荷部品に対応づけて出 力されるので、 求められた負荷電流等と共に、 必要に応じて任意の負荷部品の詳細情報が 確認できるようになり、 電気配線の解析の利便性向上及び正確性向上の一助となる。 この 負荷部品情報表示は、 例えば、 上記解析前処理中に行わせるようにしてもよい。  In this way, since the load component information corresponding to the specified load component is output in association with the load component, the detailed information of the arbitrary load component can be checked together with the required load current, etc., if necessary. This will help improve the convenience and accuracy of electrical wiring analysis. The display of the load component information may be performed, for example, during the pre-analysis processing.
また、 ステップ S 4の電圧分布計算では、 詳しくは、 図 5 Bに示すように、 ステップ S 4 0 1において、 まず解析前処理が行われる。 この解析前処理は上記ステップ S 3 0 1と 同様の処理であり、解析に必要な各種設定や情報の読み出し等が行われる。 次に、 ステツ プ S 4 0 2及びステップ S 4 0 3に進んで、 全負荷要素 （ここでは m個とする） における 電圧分布が計算される。 ここで、 負荷要素とは、 上述したように、 バルブ、 ランプ、 モー タ、 ヒューズ等の負荷部品及び電線とする。 但し、 この計算ループ中、 負荷要素が負荷部 品である場合のみ、 ステップ S 4 0 3において対応する電圧分布が計算される。 この電圧 分布は、 上記ような計算式をたて、 必要な電圧を求めることにより計算できる。 そして、 ステップ S 4 0 4において、 上記計算された各負荷電流が、 表示装置 1 3に既に表示され ている配線図に合成され表示される。 実際的な表示例を図 8に示す。  In addition, in the voltage distribution calculation in step S4, specifically, as shown in FIG. 5B, in step S401, pre-analysis processing is first performed. This pre-analysis processing is the same processing as in step S301, and various settings and information necessary for analysis are read out. Next, proceeding to step S402 and step S403, the voltage distribution in all the load elements (here, m pieces) is calculated. Here, the load elements are, as described above, load components such as bulbs, lamps, motors, and fuses, and electric wires. However, in this calculation loop, only when the load element is a load component, the corresponding voltage distribution is calculated in step S403. This voltage distribution can be calculated by calculating the necessary voltage by using the above-described formula. Then, in step S404, the calculated load currents are combined with the wiring diagram already displayed on the display device 13 and displayed. Figure 8 shows a practical display example.
図 8において、 表示装置 1 3には、 参照符号 1 3 aに示すような画面が表示される。 こ こに表示される予め設計された電気配線は、 電源 2 a、 ヒューズ 3 a〜3 e、 バルブ 4 a ~ 4 Θ、 切替器 5及びこれらを繋ぐ電線等から構成される。 そして、 負荷部品としての、 各ヒューズ 3 a〜3 Θ及び各バルブ 4 a〜4 Θにそれぞれ対応づけて、上記のようにして 計算された各負荷電流 3 a ' 〜3 Θ ' 及び 4 a ' 〜4 Θ ' が表示される。 In FIG. 8, a screen as shown by reference numeral 13a is displayed on the display device 13. Predesigned electric wiring is displayed on here is composed supply 2 a, fuse 3 a~3 e, the valve 4 a ~ 4 Θ, switch 5 and the wire or the like connecting these. The load currents 3 a ′ to 3 Θ ′ and 4 a ′ calculated as described above are respectively associated with the fuses 3 a to 3 Θ and the valves 4 a to 4 と し て as load components. ~ 4 Θ 'is displayed.
また、 これに続くステップ S 4 0 5及びステップ S 4 0 6においては、 上記ステップ S 3 0 4及びステップ S 3 0 5と同様に、 適宜、 表示中の電気配線における任意の負荷部品 に関する負荷部品情報が表示可能である。 ステップ S 4 0 5及びステップ S 4 0 6の処理 は、 上記ステップ S 3 0 4及び 3 0 5と同様であるので、 その説明は省略する。 また、 ステップ S 5の配線抵抗計算は、 詳しくは、 図 5 Cに示すように、 ステップ S 5 0 1において、 まず解析前処理が行われる。 この解析前処理は図 6 Bに示す処理に準じた 処理ステップ S 3 0 1 ' であるが、 図 6 Bに示す処理のうち、 少なくとも、 ステップ S 3 0 1 cが含まれていればよい。 すなわち、 ここでは、配線抵抗計算のために、 負荷部品情 報、 特に、 負荷部品の抵抗値に関する情報の読み出しが行われる。 なお、 ステップ S 3 0 1 dを更に含ませ、電線情報、 特に、 電線の抵抗値に関する情報の読み出しも行い、 これ も合成するとより正確性が向上する。 Further, in the subsequent steps S405 and S406, similarly to the above steps S304 and S305, load components relating to arbitrary load components in the electric wiring being displayed are appropriately determined. Information can be displayed. The processing in steps S405 and S406 is the same as that in steps S304 and S305, and a description thereof will be omitted. Further, in detail, in the wiring resistance calculation in step S5, as shown in FIG. 5C, in step S501, pre-analysis processing is first performed. This pre-analysis processing is processing step S301 'according to the processing shown in Fig. 6B, but it is sufficient that at least step S301c in the processing shown in Fig. 6B is included. That is, here, the load component information, in particular, the information relating to the resistance value of the load component is read out for calculating the wiring resistance. It should be noted that the step S301d is further included to read out the wire information, particularly the information on the resistance value of the wire, and the accuracy is further improved by synthesizing this.
次に、 ステップ S 5 0 2において配線抵抗を計算すべき負荷部品が選択され、 ステップ S 5 0 3においてこの選択した負荷部品に対する前方部品又は後方部品が選択される。次 に、 これら選択された負荷部品〜前方部品又は後方部品の合成抵抗が、 所望の配線抵抗と して計算される。 この合成抵抗の計算に際しては、 上記読み出された負荷部品情報 （電線 情報を含む場合もある） に含まれる抵抗値に関する情報が参照され、 周知のオームの法則 が利用される。 そして、 ステップ S 5 0 5において、 上記計算された配線抵抗が、 表示装 置 1 3に既に表示されている配線図に合成され表示される。 この表示イメージは、 上記図 8にて示した負荷電流の表示に類似したものであり、選択された負荷部品に対応づけてそ の値が表示される。  Next, in step S502, a load component whose wiring resistance is to be calculated is selected, and in step S503, a front component or a rear component for the selected load component is selected. Next, the combined resistance of the selected load component to the front component or the rear component is calculated as a desired wiring resistance. When calculating the combined resistance, information on the resistance value included in the read load component information (which may include wire information) is referred to, and the well-known Ohm's law is used. Then, in step S505, the calculated wiring resistance is combined with the wiring diagram already displayed on the display device 13 and displayed. This display image is similar to the display of the load current shown in FIG. 8, and the value is displayed in association with the selected load component.
なお、 計算された負荷電流、 電圧分布、 配線抵抗は、 図 9の 1 3 b、 1 3 cで示すよう に、 帳票形式で出力するようにしてもよい。 また、 図 8及び図 9で示した表示例は、 表示 装置 1 3上のみならず、 印字装置 1 4にて紙上に印刷出力するようにしてもよい。  Note that the calculated load current, voltage distribution, and wiring resistance may be output in a form as shown by 13b and 13c in FIG. The display examples shown in FIGS. 8 and 9 may be printed out not only on the display device 13 but also on paper by the printing device 14.
また、 これに続くステップ S 5 0 6及びステップ S 5 0 7においては、 上記ステップ S 3 0 4及びステップ S 3 0 5と同様に、 適宜、 表示中の電気配線における任意の負荷部品 に関する負荷部品情報が表示可能である。 ステップ S 5 0 6及びステップ S 5 0 7の処理 は、上記ステップ S 3 0 4及びステップ S 3 0 5と同様であるので、その説明は省略する。 なお、 出力とは、表示装置 1 3上への表示のみならず、 印字装置 1 4による紙上への印 刷も含む概念である。  In the subsequent steps S506 and S507, similarly to the above steps S304 and S305, load components relating to arbitrary load components in the electric wiring being displayed are appropriately determined. Information can be displayed. The processing in step S506 and step S507 is the same as that in step S304 and step S305, and a description thereof will be omitted. Note that output is a concept that includes not only display on the display device 13 but also printing on paper by the printing device 14.
