　［本開示の実施形態の説明］
　最初に本開示の実施態様を列記して説明する。 [Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
　本開示の自動車用配線システムは、次の通りである。 The wiring system for automobiles disclosed in the present disclosure is as follows.
　（１）自動車における車室内に設けられる第１電気部品と、前記自動車のうち前記車室よりも仕切パネルを隔てて前側にある前室に設けられる第２電気部品とを備えた自動車に組込まれる自動車用配線システムであって、前記自動車のうち前記仕切パネルに対して外方を通って配設され、前記第１電気部品と前記第２電気部品との間を信号伝送可能に接続する信号伝送用配線部材を備える。これにより、車室と前室との間の仕切パネルにおいて、配線挿通用の孔をなるべく少なく或は小さくすることができる。 (1) It is incorporated into an automobile having a first electric component provided in the passenger compartment of the automobile and a second electric component provided in the front chamber on the front side of the automobile with a partition panel separated from the passenger compartment. A wiring system for an automobile, which is arranged through the outside of the automobile with respect to the partition panel, and is a signal transmission that connects the first electric component and the second electric component so as to be able to transmit a signal. A wiring member for use is provided. As a result, in the partition panel between the passenger compartment and the front compartment, the holes for wiring insertion can be made as small or small as possible.
　（２）前記信号伝送用配線部材が前記自動車のフロアに対して下方に配設されていてもよい。車室内空間を広くすることができる。 (2) The signal transmission wiring member may be arranged below the floor of the automobile. The interior space of the vehicle can be widened.
　（３）前記信号伝送用配線部材は、前記自動車における前席よりも後方に配設される前記第１電気部品に接続されてもよい。第１電気部品が前席よりも後方にあるため、第１電気部品が前席の前側にあるインストルメントパネル周辺のスペースを圧迫することが抑制される。 (3) The signal transmission wiring member may be connected to the first electric component arranged behind the front seat in the automobile. Since the first electric component is located behind the front seat, it is possible to prevent the first electric component from squeezing the space around the instrument panel on the front side of the front seat.
　（４）前記信号伝送用配線部材は、前記自動車のうち前記前席よりも後ろに形成された配線用孔を通って配設されてもよい。配線用孔が前席よりも後ろにあるので、車室外からの音が車室内に伝わっても、当該音は前席に座る乗員には聞え難い。 (4) The signal transmission wiring member may be arranged through a wiring hole formed behind the front seat in the automobile. Since the wiring hole is behind the front seats, even if the sound from outside the passenger compartment is transmitted to the passenger compartment, it is difficult for the occupants sitting in the front seats to hear the sound.
　（５）前記第１電気部品及び前記第２電気部品の少なくとも一方に電源を供給する電源用配線部材の少なくとも一部が前記信号伝送用配線部材に沿って前記仕切パネルに対して外方を通って配設されてもよい。車室と前室との間の仕切パネルにおいて、電源用配線部材用の孔をなるべく少なく或は小さくすることができる。 (5) At least a part of the power supply wiring member that supplies power to at least one of the first electric component and the second electric component passes outward with respect to the partition panel along the signal transmission wiring member. May be arranged. In the partition panel between the passenger compartment and the front compartment, the holes for the power supply wiring members can be made as small or small as possible.
　（６）前記信号伝送用配線部材は、前記自動車のフロアに対して下方に設けられる高圧電源用配線とは別の経路に沿って配設されていてもよい。信号伝送用配線部材は、前記フロアに対して下方に設けられる高圧電源用配線とは別の経路に沿って配設されるため、高圧用電源用配線を備える電気自動車或はハイブリッド自動車、及び、高圧用電源用配線を備えない内燃機関自動車の両方に対して適用が容易である。 (6) The signal transmission wiring member may be arranged along a path different from the high-voltage power supply wiring provided below the floor of the automobile. Since the signal transmission wiring member is arranged along a path different from the high-voltage power supply wiring provided below the floor, the electric vehicle or hybrid vehicle provided with the high-voltage power supply wiring, and It is easy to apply to both internal combustion engine vehicles that do not have high voltage power supply wiring.
　（７）前記信号伝送用配線部材は、前記第１電気部品としての第１制御ユニットと、前記第２電気部品としての第２制御ユニットとを通信可能に接続する通信用配線部材であってもよい。第１制御ユニットと前記第２制御ユニットとを通信可能に接続することができる。 (7) Even if the signal transmission wiring member is a communication wiring member that communicably connects the first control unit as the first electric component and the second control unit as the second electric component. Good. The first control unit and the second control unit can be communicably connected.
　（８）前記第１制御ユニットと、前記車室内において前記第１制御ユニットよりも前側にある車室内前側制御ユニットとを通信可能に接続する車室内通信用配線部材をさらに備えていてもよい。車室内において、比較的後ろ側にある第１制御ユニットから比較的前側にある車室内前側制御ユニットに向けて車室内通信用配線部材が配設される。このため、車室内の前側に車室内通信用配線部材が集中し難くなり、車室内の前側において車室内スペースが広くなる。 (8) A wiring member for vehicle interior communication that connects the first control unit and the vehicle interior front control unit located in front of the first control unit in the vehicle interior so as to be communicable may be further provided. In the vehicle interior, wiring members for vehicle interior communication are arranged from the first control unit on the relatively rear side to the front side control unit in the vehicle interior on the relatively front side. For this reason, it becomes difficult for the wiring members for communication in the vehicle interior to be concentrated on the front side of the vehicle interior, and the space inside the vehicle is widened on the front side of the vehicle interior.
　（９）前記通信用配線部材は、前記第２制御ユニットから、前記第１制御ユニットを経由し、前記車室内において前記第１電気部品よりも前側にある第３制御ユニットに至る経路に沿って配設され、前記第１制御ユニットと前記第２制御ユニットと前記第３制御ユニットとを通信可能に接続してもよい。車室内において、比較的前側にある第３制御ユニットに対して後ろ側から通信用配線部材が接続される。このため、車室内の前側において通信用配線部材が少なくなり、車室内の前側において室内スペースを広くすることができる。 (9) The communication wiring member is provided along a path from the second control unit to the third control unit in front of the first electric component in the vehicle interior via the first control unit. The first control unit, the second control unit, and the third control unit may be communicably connected to each other. In the vehicle interior, the communication wiring member is connected from the rear side to the third control unit which is relatively on the front side. Therefore, the number of communication wiring members is reduced on the front side of the vehicle interior, and the interior space can be widened on the front side of the vehicle interior.

　自動車用配線システム２０は、上記自動車１０に組込まれるものであり、信号伝送用配線部材２２を備える。 The automobile wiring system 20 is incorporated in the automobile 10 and includes a signal transmission wiring member 22.
　信号伝送用配線部材２２は、信号を伝送する配線部材である。信号伝送用配線部材２２は、芯線と芯線の周囲の被覆とを有する一般電線であってもよいし、シールド線、ツイスト線、光ファイバ等であってもよい。信号伝送用配線部材２２は、１本の電線のみを含んでいてもよいし、複数の電線を含んでいてもよい。 The signal transmission wiring member 22 is a wiring member that transmits a signal. The signal transmission wiring member 22 may be a general electric wire having a core wire and a coating around the core wire, or may be a shielded wire, a twisted wire, an optical fiber, or the like. The signal transmission wiring member 22 may include only one electric wire, or may include a plurality of electric wires.
　信号伝送用配線部材２２は、自動車１０のうち仕切パネル１８の外方を通って配設され、第１電気部品３０と第２電気部品４０との間を信号伝送可能に接続する。例えば、信号伝送用配線部材２２の一端部に設けられたコネクタが前室１７内において第２電気部品４０にコネクタ接続される。信号伝送用配線部材２２の他端部に設けられたコネクタが車室１６内において第１電気部品３０にコネクタ接続される。 The signal transmission wiring member 22 is arranged through the outside of the partition panel 18 of the automobile 10, and connects the first electric component 30 and the second electric component 40 so as to be able to transmit signals. For example, a connector provided at one end of the signal transmission wiring member 22 is connected to the second electric component 40 in the front chamber 17. A connector provided at the other end of the signal transmission wiring member 22 is connected to the first electric component 30 in the vehicle interior 16.
　信号伝送用配線部材２２は、車室１６内から外に導かれる。例えば、車室１６には配線用孔１６ｈが形成され（図２参照）、信号伝送用配線部材２２は、当該配線用孔１６ｈを通って車室１６内から車室１６外に導かれる。配線用孔１６ｈは、車室１６においていずれの位置に形成されてもよい。例えば、第１電気部品３０が自動車１０の前席１１ａよりも後方に設けられる場合、配線用孔１６ｈは、前席１１ａよりも後方に設けられてもよい。例えば、第１電気部品３０は、最も後ろ側の後席１１ｂよりも後方に設けられる場合、配線用孔１６ｈは、後席１１ｂよりも後方（例えば、荷室）に設けられてもよい。配線用孔１６ｈは、車室１６のフロア１３における側部に設けられたホイールハウスの周縁に隙間として形成されてもよい。配線用孔１６ｈは、車室１６におけるフロア１３に形成されていてもよい。 The signal transmission wiring member 22 is guided from the inside to the outside of the vehicle interior 16. For example, a wiring hole 16h is formed in the vehicle interior 16 (see FIG. 2), and the signal transmission wiring member 22 is guided from the inside of the vehicle compartment 16 to the outside of the vehicle compartment 16 through the wiring hole 16h. The wiring hole 16h may be formed at any position in the vehicle interior 16. For example, when the first electric component 30 is provided behind the front seat 11a of the automobile 10, the wiring hole 16h may be provided behind the front seat 11a. For example, when the first electrical component 30 is provided behind the rearmost rear seat 11b, the wiring hole 16h may be provided behind the rear seat 11b (for example, a luggage compartment). The wiring hole 16h may be formed as a gap on the peripheral edge of the wheel house provided on the side portion of the floor 13 of the vehicle interior 16. The wiring hole 16h may be formed on the floor 13 in the vehicle interior 16.
　信号伝送用配線部材２２は、好ましくは、自動車１０のうち仕切パネル１８の外方のうち下方を通って配設される。より好ましくは、信号伝送用配線部材２２は、配線用孔１６ｈと第２電気部品４０との間において、フロア１３に対して下方を通り、ボディ１２の前後方向に延在するように配設される。 The signal transmission wiring member 22 is preferably disposed so as to pass below the outer side of the partition panel 18 of the automobile 10.

To.
　信号伝送用配線部材２２は、フロア１３の下方において直線的に配設されてもよいし、途中で曲って配設されてもよい。フロア１３の下方は、車室１６内に比べて、信号伝送用配線部材２２を配設する際の障害となる部材が少ない。このため、信号伝送用配線部材２２が、フロア１３の下方に配設されれば、信号伝送用配線部材２２を、第１電気部品３０と第２電気部品４０とを結ぶ最短経路（例えば、直線経路）で配設し易い。結果、信号伝送用配線部材２２の長さを小さくすることができ、コスト低減も可能となる。信号伝送用配線部材２２は、フロア１３の下方において、バンド付クランプ等の固定部材によって、当該フロア１３に固定されてもよい。信号伝送用配線部材２２は、コルゲートチューブ、プロテクタ等によって保護されていてもよい。 The signal transmission wiring member 22 may be arranged linearly below the floor 13 or may be arranged bent in the middle. Below the floor 13, there are fewer members that hinder the arrangement of the signal transmission wiring member 22 than in the vehicle interior 16. Therefore, if the signal transmission wiring member 22 is arranged below the floor 13, the shortest path (for example, a straight line) connecting the signal transmission wiring member 22 to the first electric component 30 and the second electric component 40 is provided. Easy to arrange by route). As a result, the length of the signal transmission wiring member 22 can be reduced, and the cost can be reduced. The signal transmission wiring member 22 may be fixed to the floor 13 below the floor 13 by a fixing member such as a clamp with a band. The signal transmission wiring member 22 may be protected by a corrugated tube, a protector, or the like.
　本自動車用配線システム２０においては、第１電気部品３０と第２電気部品４０との間で、上記信号伝送用配線部材２２を介して、信号が伝送される。 In the wiring system 20 for automobiles, a signal is transmitted between the first electric component 30 and the second electric component 40 via the signal transmission wiring member 22.
　このように構成された自動車用配線システム２０によると、信号伝送用配線部材２２は、車室１６と前室１７との間において、仕切パネル１８に対して外方を通って配設される。このため、仕切パネル１８には、信号伝送用配線部材２２を挿通するための孔を形成しなくてもよい。あるいは、他の電線が仕切パネル１８に形成された孔を通っているとしても、仕切パネル１８の外方を通る信号伝送用配線部材２２の分、当該孔を小さくできる。このため、仕切パネル１８において、配線挿通用の孔をなるべく少なく或は小さくすることができる。 According to the automobile wiring system 20 configured in this way, the signal transmission wiring member 22 is arranged between the vehicle interior 16 and the front chamber 17 through the outside with respect to the partition panel 18. Therefore, it is not necessary to form a hole in the partition panel 18 for inserting the signal transmission wiring member 22. Alternatively, even if another electric wire passes through a hole formed in the partition panel 18, the hole can be made smaller by the amount of the signal transmission wiring member 22 passing outside the partition panel 18. Therefore, in the partition panel 18, the holes for wiring insertion can be made as small or small as possible.
　仕切パネル１８において、配線挿通用の孔が少なくなり或は小さくなれば、前室１７から車室１６に向けて音が伝わりにくくなる。これにより、車室１６において静音性が向上する。また、仕切パネル１８の上下方向寸法を小さくでき、インストルメントパネルの上部の位置を下げて視界を広くすることも可能となる。 In the partition panel 18, if the number of holes for wiring insertion is reduced or reduced, it becomes difficult for sound to be transmitted from the front chamber 17 to the passenger compartment 16. As a result, quietness is improved in the vehicle interior 16. Further, the vertical dimension of the partition panel 18 can be reduced, and the position of the upper part of the instrument panel can be lowered to widen the field of view.
　仕切パネル１８において、配線挿通用の孔が少なくなれば、配線部材の貫通作業及び当該孔での止水構造、止水作業が不要となる。 If the number of holes for wiring insertion in the partition panel 18 is reduced, the work of penetrating the wiring member and the water-stopping structure and water-stopping work in the holes become unnecessary.
　また、信号伝送用配線部材２２がフロア１３に対して下方に配設される。このため、車室１６内空間を広くすることができる。また、自動車１０を外から見て、信号伝送用配線部材２２が目立ち難い。 Further, the signal transmission wiring member 22 is arranged below the floor 13. Therefore, the space inside the vehicle interior 16 can be widened. Further, when the automobile 10 is viewed from the outside, the signal transmission wiring member 22 is inconspicuous.
　また、第１電気部品３０は、前席１１ａよりも後ろにある。このため、インストルメントパネル周辺に、第１電気部品３０を配設するためのスペースを確保しなくてもよい。これにより、第１電気部品３０が前席１１ａの前側にあるインストルメントパネル周辺のスペースを圧迫することが抑制される。ひいては、インストルメントパネルの上部の位置を下げて視界を広くしたり、前席１１ａよりも前側の居住スペースを広くしたりすることができる。 Also, the first electrical component 30 is behind the front seat 11a. Therefore, it is not necessary to secure a space for arranging the first electric component 30 around the instrument panel. As a result, it is suppressed that the first electric component 30 presses the space around the instrument panel on the front side of the front seat 11a. As a result, the position of the upper part of the instrument panel can be lowered to widen the field of view, and the living space on the front side of the front seat 11a can be widened.
　また、信号伝送用配線部材２２は、自動車１０のうち前席１１ａよりも後ろに形成された配線用孔１６ｈを通って配設される。配線用孔１６ｈは、前席１１ａよりも後ろにあるので、車室１６外からの音が車室１６に伝わっても、当該音は前席１１ａに座る乗員には聞え難い。配線用孔１６ｈが後席１１ｂよりも後ろにあれば、車室１６外からの音が車室１６に伝わっても、当該音は前席１１ａ及び後席１１ｂに座る乗員には聞え難い。 Further, the signal transmission wiring member 22 is arranged through a wiring hole 16h formed behind the front seat 11a in the automobile 10. Since the wiring hole 16h is behind the front seat 11a, even if a sound from outside the passenger compartment 16 is transmitted to the passenger compartment 16, the sound is difficult for the occupant sitting in the front seat 11a to hear. If the wiring hole 16h is behind the rear seat 11b, even if the sound from outside the passenger compartment 16 is transmitted to the passenger compartment 16, the sound is difficult for the occupants sitting in the front seat 11a and the rear seat 11b to hear.
　[実施形態２]
　実施形態２に係る自動車用配線システム１２０について説明する。図３は自動車用配線システム１２０が適用された自動車１０を示す概略平面図である。なお、本実施形態２の説明において、実施形態１で説明したものと同様構成要素については同一符号を付してその説明を省略する。 [Embodiment 2]
The automobile wiring system 120 according to the second embodiment will be described. FIG. 3 is a schematic plan view showing an automobile 10 to which the automobile wiring system 120 is applied. In the description of the second embodiment, the same components as those described in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
　本自動車用配線システム１２０が、上記自動車用配線システム２０と異なるのは次の点である。すなわち、第１電気部品３０は第１制御ユニット１３０であり、第２電気部品４０は第２制御ユニット１４０である。このため、信号伝送用配線部材２２に対応する信号伝送用配線部材１２２は、第１制御ユニット１３０と第２制御ユニット１４０とを通信可能に接続する。信号伝送用配線部材１２２がボディ１２に対して配設される経路等は、上記実施形態１で説明したのと同様構成である。 The automobile wiring system 120 is different from the automobile wiring system 20 in the following points. That is, the first electric component 30 is the first control unit 130, and the second electric component 40 is the second control unit 140. Therefore, the signal transmission wiring member 122 corresponding to the signal transmission wiring member 22 connects the first control unit 130 and the second control unit 140 in a communicable manner. The path or the like in which the signal transmission wiring member 122 is arranged with respect to the body 12 has the same configuration as that described in the first embodiment.
　第１制御ユニット１３０及び第２制御ユニット１４０は、ＣＰＵ（Central Processing Unit）を備えるコンピュータによって構成されており、自動車１０に搭載された各種電気部品を制御する。例えば、第２制御ユニット１４０は、通信線１４４を介して各種電気機器１４２に接続されている。第１制御ユニット１３０及び第２制御ユニット１４０は、通信回路を備えており、当該通信回路及び信号伝送用配線部材１２２を通じて、通信を行う。 The first control unit 130 and the second control unit 140 are composed of a computer including a CPU (Central Processing Unit), and control various electric components mounted on the automobile 10. For example, the second control unit 140 is connected to various electric devices 142 via a communication line 144. The first control unit 130 and the second control unit 140 include a communication circuit, and communicate with each other through the communication circuit and the signal transmission wiring member 122.
　ここでは、第１制御ユニット１３０は、通信プロトコルの変換を行うゲートウエイを備えており、車室１６内に配設されるエリアＥＣＵ１５０，１５１、１５２、１５３にも接続される。 Here, the first control unit 130 is provided with a gateway that converts the communication protocol, and is also connected to the areas ECUs 150, 151, 152, and 153 arranged in the vehicle interior 16.
　エリアＥＣＵ１５０，１５１、１５２、１５３は、自動車１０に搭載された各種制御対象部品を複数のエリアに分けて分散制御する制御ユニットである。図３に示す例では、車室１６内における前側の左右にエリアＥＣＵ１５０，１５１が設けられ、車室１６内における後側の左右にエリアＥＣＵ１５２、１５３が設けられる。前側のエリアＥＣＵ１５０、１５１は、第１制御ユニット１３０よりも前側にある車室前側制御ユニットの一例である。 Area ECUs 150, 151, 152, and 153 are control units for distributed control of various control target parts mounted on the automobile 10 by dividing them into a plurality of areas. In the example shown in FIG. 3, the area ECUs 150 and 151 are provided on the left and right sides of the front side in the passenger compartment 16, and the area ECUs 152 and 153 are provided on the left and right sides of the rear side in the passenger compartment 16. The front area ECUs 150 and 151 are examples of vehicle interior front control units located in front of the first control unit 130.
　各エリアＥＣＵ１５０，１５１、１５２、１５３は、自己に対応づけられた電気部品１６０に通信線１６２を介して通信可能に接続されている。各エリア１５０，１５１、１５２、１５３は、通信線１６２を介して接続された電気部品１６０との間で、検出信号の受信、制御信号の送受信等を行う。エリアＥＣＵ１５０、１５１、１５２、１５３のいずれかからルーフに向う通信線が延在していてもよい。 Each area ECU 150, 151, 152, 153 is communicably connected to the electric component 160 associated with itself via the communication line 162. Each of the areas 150, 151, 152, and 153 receives a detection signal, transmits and receives a control signal, and the like with the electric component 160 connected via the communication line 162. A communication line from any of the area ECUs 150, 151, 152, and 153 to the roof may extend.
　第１制御ユニット１３０と、エリアＥＣＵ１５０，１５１、１５２、１５３とは、車室内通信用配線部材１２４を介して通信可能に接続されている。ここでは、車室内通信用配線部材１２４は、車室１６内において、一側前後方向に沿って配設される部分と、前側車幅方向に沿って配設される部分と、他側前後方向に沿って配設される部分とを含む。第１制御ユニット１３０及び第１制御ユニット１３０と、エリアＥＣＵ１５０，１５１、１５２、１５３が、バス型の接続形式で、車室内通信用配線部材１２４に接続されている。より具体的には、車室１６内の後方一側において、エリアＥＣＵ１５０及び第１制御ユニット１３０が車室内通信用配線部材１２４に接続されている。車室１６内の前方一側においてエリアＥＣＵ１５１が車室内通信用配線部材１２４に接続され、車室１６内の前方他側においてエリアＥＣＵ１５２が車室内通信用配線部材１２４に接続されている。車室１６内の後方他側において、エリアＥＣＵ１５３が車室内通信用配線部材１２４に接続されている。 The first control unit 130 and the area ECUs 150, 151, 152, and 153 are communicably connected via the vehicle interior communication wiring member 124. Here, the vehicle interior communication wiring member 124 is arranged in the vehicle interior 16 along the front-rear direction on one side, the portion arranged along the width direction on the front side, and the front-rear direction on the other side. Includes a portion arranged along. The first control unit 130 and the first control unit 130, and the area ECUs 150, 151, 152, and 153 are connected to the vehicle interior communication wiring member 124 in a bus-type connection form. More specifically, the area ECU 150 and the first control unit 130 are connected to the vehicle interior communication wiring member 124 on one rear side in the vehicle interior 16. The area ECU 151 is connected to the vehicle interior communication wiring member 124 on one front side in the vehicle interior 16, and the area ECU 152 is connected to the vehicle interior communication wiring member 124 on the front other side in the vehicle interior 16. The area ECU 153 is connected to the vehicle interior communication wiring member 124 on the rear other side in the vehicle interior 16.
　上記接続態様を第１制御ユニット１３０とエリアＥＣＵ１５１、１５２とに着目して説明する。車室内通信用配線部材１２４は、車室１６内において第１制御ユニット１３０と、当該第１制御ユニット１３０よりも前側にある車室内制御ユニットとしてのエリアＥＣＵ１５１、１５２とを通信可能に接続する。 The above connection mode will be described focusing on the first control unit 130 and the area ECUs 151 and 152. The vehicle interior communication wiring member 124 connects the first control unit 130 and the area ECUs 151 and 152 as vehicle interior control units on the front side of the first control unit 130 so as to be communicable in the vehicle interior 16.
　なお、上記第１制御ユニット１３０及び第２制御ユニット１４０の少なくとも一方には、電源分配を行うジャンクションボックスが組込まれていてもよい。 Note that at least one of the first control unit 130 and the second control unit 140 may incorporate a junction box for power distribution.
　本自動車用配線システム１２０によると、上記実施形態２と同様の作用効果を得ることができる。また、仕切パネル１８に対して外方を通る信号伝送用配線部材２２によって第１制御ユニット１３０と第２制御ユニット１４０とを通信可能に接続することができる。 According to the wiring system 120 for automobiles, the same operation and effect as in the second embodiment can be obtained. Further, the first control unit 130 and the second control unit 140 can be communicably connected to the partition panel 18 by the signal transmission wiring member 22 passing outside.
　ここで、第１制御ユニット１３０に対して比較的多数の電気機器が接続されることが想定される。例えば、第１制御ユニット１３０に、複数のＥＣＵの統合制御を行う中央ＥＣＵとしての機能を持たせること、駆動系、ボディ系、情報系の各種機器１７０が、通信線１７２を介して第１制御ユニット１３０に接続されることが想定される。第１制御ユニット１３０は、前室１７内の第２制御ユニット１４０と通信可能に接続されているため、そのような中央ＥＣＵとしての機能を持たせるのに適している。本実施形態では、前室１７内の第２制御ユニット１４０と通信を行う第１制御ユニット１３０が車室１６内において比較的後側に配設されている。そして、車室１６内において、比較的後側にある第１制御ユニット１３０から比較的前側にある車室内前側制御ユニットとしてのエリアＥＣＵ１５１、１５２に向けて車室内通信用配線部材１２４が配設される。このため、車室内通信用の配線部材が車室１６内の前側に集中することが抑制される。これにより、インストルメントパネルの高さを低くしたり、車室１６内の前側において車室内の居住スペースを広くしたりすることができる。 Here, it is assumed that a relatively large number of electric devices are connected to the first control unit 130. For example, the first control unit 130 is provided with a function as a central ECU that performs integrated control of a plurality of ECUs, and various devices 170 of the drive system, the body system, and the information system are first controlled via the communication line 172. It is assumed that it will be connected to the unit 130. Since the first control unit 130 is communicably connected to the second control unit 140 in the front chamber 17, it is suitable for having such a function as a central ECU. In the present embodiment, the first control unit 130 that communicates with the second control unit 140 in the front chamber 17 is arranged relatively rearward in the vehicle interior 16. Then, in the vehicle interior 16, the wiring member 124 for vehicle interior communication is arranged from the first control unit 130 on the relatively rear side toward the areas ECUs 151 and 152 as the vehicle interior front side control units on the relatively front side. Car. Therefore, it is possible to prevent the wiring members for vehicle interior communication from being concentrated on the front side in the vehicle interior 16. As a result, the height of the instrument panel can be lowered, and the living space in the passenger compartment can be widened on the front side in the passenger compartment 16.
　実施形態２において、自動車用配線システム１２０に電源用配線部材を付加した例を説明する。図４は電気自動車２１０を前提として電源用配線部材２２２Ａ、２２２Ｂを付加した例を示す概略平面図である。図５は内燃機関自動車３１０を前提として電源用配線部材３２２Ａ、３２２Ｂを付加した例を示す概略平面図である。 In the second embodiment, an example in which a power supply wiring member is added to the automobile wiring system 120 will be described. FIG. 4 is a schematic plan view showing an example in which the power supply wiring members 222A and 222B are added on the premise of the electric vehicle 210. FIG. 5 is a schematic plan view showing an example in which the power supply wiring members 322A and 322B are added on the premise of the internal combustion engine vehicle 310.

As shown in FIG. 4, the electric vehicle 210 includes a high-voltage battery 250, an inverter 252, a motor 254, a DC-DC converter 256, a low-voltage battery 258, and a relay 259.
　高電圧バッテリ２５０は、電気自動車２１０を走行させるためのモータ２５４の駆動に適した電圧を供給する電源（例えば、リチウムイオンバッテリ等）であり、例えば、９０Ｖ～５００Ｖの電圧を供給する。高電圧バッテリ２５０の電圧は、低電圧バッテリ２５８の電圧よりも高い。高電圧バッテリ２５０は、インバータ２５２を介してモータ２５４に接続されている。高電圧バッテリ２５０から供給される電力は、インバータ２５２を介して交流に変換された後、モータ２５４に供給される。モータ２５４の駆動によって電気自動車２１０が走行する。 The high voltage battery 250 is a power source (for example, a lithium ion battery) that supplies a voltage suitable for driving a motor 254 for driving an electric vehicle 210, and supplies a voltage of, for example, 90V to 500V. The voltage of the high voltage battery 250 is higher than the voltage of the low voltage battery 258. The high voltage battery 250 is connected to the motor 254 via the inverter 252. The electric power supplied from the high-voltage battery 250 is converted to alternating current via the inverter 252 and then supplied to the motor 254. The electric vehicle 210 runs by driving the motor 254.
　また、高電圧バッテリ２５０は、ＤＣ－ＤＣコンバータ２５６に接続されている。ＤＣ－ＤＣコンバータ２５６は、高電圧バッテリ２５０の高電圧を、低電圧バッテリ２５８の電圧に合わせて、低電圧に変換する。 Further, the high voltage battery 250 is connected to the DC-DC converter 256. The DC-DC converter 256 converts the high voltage of the high voltage battery 250 into a low voltage in accordance with the voltage of the low voltage battery 258.
　ＤＣ－ＤＣコンバータ２５６は、第１制御ユニット１３０及び第２制御ユニット１４０に接続されている。ＤＣ－ＤＣコンバータ２５６と第１制御ユニット１３０とを接続する配線部材は、第１制御ユニット１３０に電源を供給する電源用配線部材２２２Ａである。ＤＣ－ＤＣコンバータ２５６は、リレー２５９を介して低電圧バッテリ２５８にも接続されている。リレー２５９がオンオフ制御されることで、低電圧バッテリ２５８に対する充電状態と非充電状態とが切替えられる。 The DC-DC converter 256 is connected to the first control unit 130 and the second control unit 140. The wiring member that connects the DC-DC converter 256 and the first control unit 130 is a power supply wiring member 222A that supplies power to the first control unit 130. The DC-DC converter 256 is also connected to the low voltage battery 258 via a relay 259. By controlling the relay 259 on and off, the charged state and the non-charged state of the low-voltage battery 258 can be switched.

　次に、内燃機関自動車３１０についての例を説明する。図５に示すように，内燃機関自動車３１０は、発電機３５０、低電圧バッテリ３５２、補助低電圧バッテリ３５４、リレー３５６を備える。 Next, an example of the internal combustion engine vehicle 310 will be described. As shown in FIG. 5, the internal combustion engine vehicle 310 includes a generator 350, a low-voltage battery 352, an auxiliary low-voltage battery 354, and a relay 356.
　発電機３５０は、内燃機関３６０の駆動によって発電する装置である。発電機３５０は、低電圧バッテリ３５２及び第２制御ユニット１４０に接続されている。 The generator 350 is a device that generates electricity by driving an internal combustion engine 360. The generator 350 is connected to the low voltage battery 352 and the second control unit 140.
　低電圧バッテリ３５２は、補機バッテリとも呼ばれるバッテリ（例えば、鉛バッテリ等）であり、例えば、５Ｖ～５９Ｖの電圧を供給する。低電圧バッテリ３５２は、第１制御ユニット１３０に接続されている。低電圧バッテリ３５２と第１制御ユニット１３０とを接続する配線部材は、第１制御ユニット１３０に電源を供給する電源用配線部材３２２Ａである。低電圧バッテリ３５２は、リレー３５６を介して補助低電圧バッテリ３５４にも接続されている。リレー３５６がオンオフ制御されることで、補助低電圧バッテリ３５４に対する充電状態と非充電状態とが切替えられる。 The low voltage battery 352 is a battery (for example, a lead battery) which is also called an auxiliary battery, and supplies a voltage of, for example, 5V to 59V. The low voltage battery 352 is connected to the first control unit 130.

　本実施形態では、発電機３５０、低電圧バッテリ３５２は、前室１７内に設けられている。補助低電圧バッテリ３５４及びリレー３５６は車室１６内に設けられている。補助低電圧バッテリ３５４及びリレー３５６は、好ましくは、前席よりも後ろ、より好ましくは、後席よりも後ろに設けられる。 In the present embodiment, the generator 350 and the low voltage battery 352 are provided in the front chamber 17. The auxiliary low voltage battery 354 and the relay 356 are provided in the passenger compartment 16. The auxiliary low voltage battery 354 and relay 356 are preferably provided behind the front seats, more preferably behind the rear seats.
　上記電源用配線部材３２２Ａ、３２２Ｂは、車室１６内における電気部品と前室１７内における電気部品とを接続する配線部材である。このため、端部の接続構成等を除き、上記電気自動車２１０における電源用配線部材２２２Ａ、２２２Ｂと同様構成とすることができる。 The power supply wiring members 322A and 322B are wiring members that connect the electric parts in the passenger compartment 16 and the electric parts in the front chamber 17. Therefore, the configuration can be the same as that of the power supply wiring members 222A and 222B in the electric vehicle 210, except for the connection configuration of the end portion.
　これらの電気自動車２１０或は内燃機関自動車３１０における適用例で説明したように、第１制御ユニット１３０及び第２制御ユニット１４０の少なくとも一方に電源を供給する電源用配線部材２２２Ａ、２２２Ｂ、３２２Ａ、３２２Ｂの少なくとも一部が信号伝送用配線部材１２２に沿って仕切パネル１８に対して外方を通って配設されてもよい。これにより、仕切パネル１８において、電源用配線部材用の孔をなるべく少なくできるか或は小さくできる。 As described in the application example in these electric vehicle 210 or internal combustion engine vehicle 310, power supply wiring members 222A, 222B, 222A, and 222B that supply power to at least one of the first control unit 130 and the second control unit 140. At least a part of the above may be arranged along the signal transmission wiring member 122 through the outside with respect to the partition panel 18. As a result, in the partition panel 18, the number of holes for the power supply wiring member can be reduced or reduced as much as possible.
　前室内の電気部品と車室内の電気部品とを接続する全ての配線部材が仕切パネルの外方、例えば、仕切パネルの下方を通る構成とすれば、仕切パネルにおいて、配線部材を挿通孔が無くなる。これにより、前室から車室内に音が伝わり難くなり、車室内の静音性が向上する。また、仕切パネルに対する配線部材の挿通作業、止水作業が不要となる。 If all the wiring members that connect the electric parts in the front room and the electric parts in the vehicle interior pass outside the partition panel, for example, below the partition panel, the partition panel has no insertion holes for the wiring members. .. As a result, it becomes difficult for sound to be transmitted from the front chamber to the passenger compartment, and the quietness in the passenger compartment is improved. In addition, it is not necessary to insert the wiring member into the partition panel and stop the water.
　もっとも、前室内の電気部品と車室内の電気部品とを接続する全ての配線部材の一部が仕切パネルの外方を通り、残部が仕切パネルに形成された孔を通って配設されてもよい。一部の配線部材が仕切パネルの外方を通る分、仕切パネル１８において、電源用配線部材用の孔をなるべく少なく或は小さくすることができるからである。 However, even if a part of all the wiring members connecting the electric parts in the front interior and the electric parts in the passenger compartment pass through the outside of the partition panel and the rest pass through the holes formed in the partition panel. Good. This is because the number of holes for the power supply wiring member in the partition panel 18 can be made as small or small as possible because some of the wiring members pass outside the partition panel.
　また、電気自動車２１０において、信号伝送用配線部材１２２は、フロア１３に対して下方に設けられる高電圧用配線部材２６０、２６１とは別の経路に沿って配設されている。このため、信号伝送用配線部材１２２が設計製造される際、信号伝送用配線部材１２２が電気自動車２１０に組込まれる際等に、高電圧用配線部材２６０、２６１の存在を前提として考慮することが不要となる。このため、信号伝送用配線部材１２２を、高電圧用配線部材２６０、２６１が無い内燃機関自動車３１０に適用することが容易となる。もちろん、信号伝送用配線部材１２２を、高電圧用配線部材２６０、２６１を備えるハイブリッド自動車に適用することも容易である。 Further, in the electric vehicle 210, the signal transmission wiring member 122 is arranged along a path different from the high voltage wiring members 260 and 261 provided below the floor 13. Therefore, when the signal transmission wiring member 122 is designed and manufactured, when the signal transmission wiring member 122 is incorporated into the electric vehicle 210, etc., the existence of the high voltage wiring members 260 and 261 is considered as a premise. It becomes unnecessary. Therefore, it becomes easy to apply the signal transmission wiring member 122 to the internal combustion engine vehicle 310 without the high voltage wiring members 260 and 261. Of course, it is also easy to apply the signal transmission wiring member 122 to a hybrid vehicle including the high voltage wiring members 260 and 261.
　[実施形態３]
　実施形態３に係る自動車用配線システム４２０について説明する。図６は自動車用配線システム４２０が適用された自動車１０を示す概略平面図である。なお、本実施形態３の説明において、実施形態１或は２で説明したものと同様構成要素については同一符号を付してその説明を省略する。 [Embodiment 3]
The automobile wiring system 420 according to the third embodiment will be described. FIG. 6 is a schematic plan view showing an automobile 10 to which the automobile wiring system 420 is applied. In the description of the third embodiment, the same components as those described in the first or second embodiment are designated by the same reference numerals, and the description thereof will be omitted.
　本自動車用配線システム４２０が、上記自動車用配線システム２０と異なるのは次の点である。すなわち、実施形態２と同様に、第１電気部品３０は第１制御ユニット１３０であり、第２電気部品４０は第２制御ユニット１４０である。このため、信号伝送用配線部材２２に対応する信号伝送用配線部材４２２は、第１制御ユニット１３０と第２制御ユニット１４０とを通信可能に接続する。信号伝送用配線部材４２２がボディ１２に対して配設される経路等は、上記実施形態１で説明したのと同様構成である。 The automobile wiring system 420 differs from the automobile wiring system 20 in the following points. That is, as in the second embodiment, the first electric component 30 is the first control unit 130, and the second electric component 40 is the second control unit 140. Therefore, the signal transmission wiring member 422 corresponding to the signal transmission wiring member 22 connects the first control unit 130 and the second control unit 140 in a communicable manner. The path or the like in which the signal transmission wiring member 422 is arranged with respect to the body 12 has the same configuration as that described in the first embodiment.
　第１制御ユニット１３０及び第２制御ユニット１４０は、車室１６内に配設されるエリアＥＣＵ１５０，１５１、１５２、１５３にも接続される。エリアＥＣＵ１５０，１５１、１５２、１５３は、実施形態２で説明したのと同様構成である。 The first control unit 130 and the second control unit 140 are also connected to the areas ECUs 150, 151, 152, and 153 arranged in the vehicle interior 16. Area ECUs 150, 151, 152, and 153 have the same configurations as described in the second embodiment.
　本自動車用配線システム４２０が実施形態２と異なる構成は、第１制御ユニット１３０、第２制御ユニット１４０及びエリアＥＣＵ１５０，１５１、１５２、１５３が、バス型の接続形式で、信号伝送用配線部材４２２に接続されていることである。なお、第１制御ユニット１３０は、通信プロトコルの変換を行うゲートウエイを備えていなくてもよい。 The configuration in which the wiring system 420 for automobiles is different from that of the second embodiment is that the first control unit 130, the second control unit 140, and the area ECUs 150, 151, 152, and 153 are in a bus type connection type, and the signal transmission wiring member 422 is used. It is connected to. The first control unit 130 does not have to include a gateway that converts the communication protocol.
　ここでは、信号伝送用配線部材４２２は、第２制御ユニット１４０から延出し、仕切パネル１８の下方及びフロア１３の下方を通ってボディ１２の後方に導かれる。信号伝送用配線部材４２２は、車室１６において第１制御ユニット１３０の配設位置又は当該配設位置よりも後方の位置において車室１６内に導か、車室１６内に沿って配設される。ここでは、信号伝送用配線部材４２２は、車室１６内において、一側から前部を通り他側に至る経路に沿って配設される。 Here, the signal transmission wiring member 422 extends from the second control unit 140 and is guided to the rear of the body 12 through below the partition panel 18 and below the floor 13. The signal transmission wiring member 422 is guided into the vehicle interior 16 at the arrangement position of the first control unit 130 or a position behind the arrangement position in the vehicle interior 16, and is arranged along the inside of the vehicle interior 16. .. Here, the signal transmission wiring member 422 is arranged in the vehicle interior 16 along a path from one side to the other side through the front portion.
　前室１７内において、第２制御ユニット１４０が信号伝送用配線部材４２２に対してバス形式で接続される。車室１６内において、第１制御ユニット１３０及びエリアＥＣＵ１５０，１５１、１５２、１５３が信号伝送用配線部材４２２に対してバス形式で接続される。このため、第１制御ユニット１３０、第２制御ユニット１４０及びエリアＥＣＵ１５０，１５１、１５２、１５３は、共通する通信経路を介して通信を行う。 In the front chamber 17, the second control unit 140 is connected to the signal transmission wiring member 422 in a bus manner. In the passenger compartment 16, the first control unit 130 and the area ECUs 150, 151, 152, and 153 are connected to the signal transmission wiring member 422 in a bus manner. Therefore, the first control unit 130, the second control unit 140, and the area ECUs 150, 151, 152, and 153 communicate via a common communication path.
　本実施形態において、上記エリアＥＣＵ１５１、１５２は、車室１６内において第１制御ユニット１３０よりも前側にある第３制御ユニットの一例である。信号伝送用配線部材４２２は、第２制御ユニット１４０から第１制御ユニット１３０を経由し、第３制御ユニットの一例であるエリアＥＣＵ１５１、１５２に至る経路に沿って配設される部分を含む。 In the present embodiment, the area ECUs 151 and 152 are examples of the third control unit located in the vehicle interior 16 in front of the first control unit 130. The signal transmission wiring member 422 includes a portion arranged along a path from the second control unit 140 to the areas ECUs 151 and 152, which are examples of the third control unit, via the first control unit 130.
　本自動車用配線システム４２０によると、上記実施形態２と同様の作用効果を得ることができる。また、仕切パネル１８に対して外方を通る信号伝送用配線部材４２２によって第１制御ユニット１３０と第２制御ユニット１４０とを通信可能に接続することができる。 According to the wiring system 420 for automobiles, the same operation and effect as in the second embodiment can be obtained. Further, the first control unit 130 and the second control unit 140 can be communicably connected to the partition panel 18 by the signal transmission wiring member 422 passing outside.
　ここで、実施形態２と同様に第１制御ユニット１３０に対しては比較的多数の電気機器が接続されることが想定される。本実施形態では、信号伝送用配線部材４２２は、第２制御ユニット１４０から第１制御ユニット１３０を経由し、第３制御ユニットの一例であるエリアＥＣＵ１５１、１５２に至る経路に沿って配設されている。第１制御ユニット１３０は、車室１６内において、比較的後側に位置して、信号伝送用配線部材４２２に接続されている。このため、第１制御ユニット１３０に対して比較的多数の電気機器が接続されることが想定されたとしても、車室内通信用の配線部材が車室１６内の前側に集中することが抑制される。これにより、インストルメントパネルの高さを低くしたり、車室１６内の前側において車室内の居住スペースを広くしたりすることができる。 Here, it is assumed that a relatively large number of electric devices are connected to the first control unit 130 as in the second embodiment. In the present embodiment, the signal transmission wiring member 422 is arranged along the path from the second control unit 140 to the areas ECUs 151 and 152, which are examples of the third control unit, via the first control unit 130. There is. The first control unit 130 is located relatively rearward in the vehicle interior 16 and is connected to the signal transmission wiring member 422. Therefore, even if it is assumed that a relatively large number of electric devices are connected to the first control unit 130, it is possible to prevent the wiring members for vehicle interior communication from concentrating on the front side in the vehicle interior 16. To. As a result, the height of the instrument panel can be lowered, and the living space in the passenger compartment can be widened on the front side in the passenger compartment 16.
　[変形例]
　なお、上記室内におけるＥＣＵの全てが、室内において前席よりも後方に配設されてもよいし、後席よりも後方に配設されてもよい。 [Modification example]
All of the ECUs in the room may be arranged behind the front seats or behind the rear seats in the room.
　なお、上記各実施形態及び各変形例で説明した各構成は、相互に矛盾しない限り適宜組合わせることができる。 It should be noted that the configurations described in each of the above embodiments and each modification can be appropriately combined unless they contradict each other.
　例えば、実施形態１及び実施形態３においても、実施形態２において説明したように、電源用配線部材が信号伝送用配線部材に沿って配設されてもよい。 For example, also in the first embodiment and the third embodiment, as described in the second embodiment, the power supply wiring member may be arranged along the signal transmission wiring member.
　また、例えば、実施形態１及び実施形態３においても、実施形態２において説明したように、信号伝送用配線部材が高電圧用配線部材とは別の経路に沿って配設されてもよい。また、実施形態２と実施形態３とが組合わされ、信号伝送用配線部材２２２を用いた複数のＥＣＵの接続と、車室内通信用配線部材１２４を用いた複数のＥＣＵの接続とが組合わされてもよい。 Further, for example, also in the first embodiment and the third embodiment, as described in the second embodiment, the signal transmission wiring member may be arranged along a path different from that of the high voltage wiring member. Further, the second embodiment and the third embodiment are combined, and the connection of a plurality of ECUs using the signal transmission wiring member 222 and the connection of a plurality of ECUs using the vehicle interior communication wiring member 124 are combined. May be good.
