Description

本発明は、車室環境用機能部品接続システムに関する。 The present invention relates to a functional component connection system for a cabin environment.

車両では、仕様（グレード）の違いによる機能の有無への対応が必要となる。特に、エアコンディショナ（Ａ／Ｃ）等の車室環境の制御に係わる機能部品は、グレード（ＬＯ、ＭＩＤ、Ｈｉ）が高くなるにつれて数が増加する。
これらＡ／Ｃ等の車室環境の制御に係わる機能部品としては、例えば、図７に示す日射センサ５０１、Ａ／Ｃプレッシャセンサ５０３、外気温センサ５０５、ＥＣＯスイッチ５０７、内気温センサ５０９、ＰＴＣヒータ５１１、ＭＧＣ５１３、Ａ／Ｃコンプレッサー５１５、ＤＥＦ５１７、イオンジェネレータ５１９、フローセンサ５２１、日射センサ５２３、シートＨＴＲ５２５、室内送風ブロア５２７、温湿度センサ５２９、排気センサ５３１、リヤＡ／Ｃスイッチ５３３、ＤＥＩＣＥＲ５３５、送風シートＤ席５３７、送風シートＰ席５３９、シートヒータＤ席５４１、シートヒータＰ席５４３、リヤＡ／Ｃ５４５におけるスモークセンサ５４７、ブロアモータコントローラ５４９、リヤブロアモータサブＡＳＳＹ５５１、リヤマグネットバルブ５５３、サーボモータ５５５、Ｎｏ１クーラーサーミスタ５５７等が挙げられる。以下、本明細書中、これらの機能部品を、「車室環境用機能部品」と称す。これらの車室環境用機能部品は、一般的に、電子制御ユニットに接続されて制御される。 In vehicles, it is necessary to cope with the presence or absence of functions due to differences in specifications (grades). In particular, functional parts related to control of the cabin environment such as an air conditioner (A / C) increase in number as the grade (LO, MID, Hi) increases.
As functional components related to control of the cabin environment such as A / C, for example, a solar radiation sensor 501, an A / C pressure sensor 503, an outside air temperature sensor 505, an ECO switch 507, an inside air temperature sensor 509, a PTC shown in FIG. Heater 511, MGC 513, A / C compressor 515, DEF 517, ion generator 519, flow sensor 521, solar radiation sensor 523, sheet HTR 525, indoor blower 527, temperature and humidity sensor 529, exhaust sensor 531, rear A / C switch 533, DEICER 535 , Blower sheet D seat 537, Blower sheet P seat 539, seat heater D seat 541, seat heater P seat 543, smoke sensor 547 in rear A / C 545, blower motor controller 549, rear blower motor sub ASSI 551, rear magne Tobarubu 553, servo motor 555, No1 cooler thermistor 557, and the like. Hereinafter, in the present specification, these functional components will be referred to as “functional components for vehicle cabin environment”. These cabin environment functional components are generally connected to and controlled by an electronic control unit.

また、近年では、車両に搭載される複数の車両電装品を制御する通信システムとして、各車両電装品を制御する複数の電子制御ユニット（以下、「ＥＣＵ（Electronic Control Unit）」と称す）がそれぞれ共通の多重通信線で接続され、その多重通信線を介して多重化された信号の授受を行い、これに基づいて各車両電装品の作動を制御するようにした車両ネットワークシステムが用いられている（例えば、特許文献１参照）。 Also, in recent years, as a communication system for controlling a plurality of vehicle electrical components mounted on a vehicle, a plurality of electronic control units (hereinafter referred to as "ECUs (Electronic Control Unit)") for controlling the respective vehicle electrical components A vehicle network system is used which is connected by a common multiplex communication line, transmits and receives multiplexed signals through the multiplex communication line, and controls the operation of each vehicle electric component based on this. (See, for example, Patent Document 1).

従来の車室環境用機能部品の組付は、それぞれのグレード（ＬＯ、ＭＩＤ、Ｈｉ）ごとに、異なる３種類のＡ／Ｃ用ＥＣＵ−ＬＯ５５９、Ａ／Ｃ用ＥＣＵ−ＭＩＤ５６１、Ａ／Ｃ用ＥＣＵ―Ｈｉ５６３）がワイヤハーネスによって接続されていた。車両に配索されるワイヤハーネスは、例えばシステム回路毎にサブ分けされた複数の回路別サブハーネスが組み合されて全体のワイヤハーネスとされているものが一般的である。システム回路としては、例えば、日射センサ５０１やＡ／Ｃプレッシャセンサ５０３等のようにＬＯグレードの車室環境用機能部品を構成に含むスタンダード回路と、排気センサ５３１やリヤＡ／Ｃスイッチ５３３等のようにＨｉグレードの車室環境用機能部品を含むオプション回路とがある。そして、このような自動車用ワイヤハーネスを製造する場合には、コネクタの配置や端子、電線の種類等を考慮しながら、全体のワイヤハーネスが適切なものとなるようにそれぞれが決定される。 Assembling of conventional functional components for car cabin environment, for each grade (LO, MID, Hi), three different types of A / C ECU-LO 559, A / C ECU-MID 561, for A / C The ECU (Hi-563) was connected by a wire harness. As a wire harness to be routed to a vehicle, for example, a plurality of circuit-specific sub-harnesses divided into sub-systems for each system circuit are generally combined to form the entire wire harness. As a system circuit, for example, a standard circuit including functional components of the LO environment such as a solar radiation sensor 501 and an A / C pressure sensor 503, an exhaust sensor 531, a rear A / C switch 533, etc. There is an optional circuit that includes functional components for Hi grade car cabin environment. And when manufacturing such a wire harness for motor vehicles, each is determined so that the whole wire harness may become appropriate, considering the arrangement of a connector, a terminal, the kind of electric wire, etc.

ところで、これまでの機能追加は、大別して仕様別対応方式と、付捨て方式と、これらを組み合わせた方式と、によって対応がなされてきた。
しかしながら、仕様別対応方式は、３種類のＡ／Ｃ用ＥＣＵ−ＬＯ５５９、Ａ／Ｃ用ＥＣＵ−ＭＩＤ５６１、Ａ／Ｃ用ＥＣＵ−Ｈｉ５６３が必要となり、更にはこれに伴って、ＥＣＵ（ドライバ）または電源分配ボックスのバリエーションが増える問題があった。
また、付捨て方式は、追加される機能をあらかじめＥＣＵ（ドライバ）または電源分配ボックス内に備えておくため、機能が付かない時のスペースと付捨て部品の無駄が発生した。更に、付捨て方式の場合、ＬＯグレード、ＭＩＤグレードに対しては、搭載済み部品の付外し作業が発生する。特に、付捨て方式を１種類で対応する場合にはＨｉグレードを使用する必要があり、付捨て部品の無駄や付外し作業の増加が顕著となった。 By the way, the addition of the function up to now has been roughly classified into a specification-based correspondence system, a discarding system, and a system combining these.
However, the specification support method requires three types of A / C ECU-LO 559, A / C ECU-MID 561, and A / C ECU-Hi 563, and, along with this, the ECU (driver) or There was a problem that the variation of the power distribution box increased.
Moreover, since the discarding method prepares the added function in the ECU (driver) or the power supply distribution box in advance, a waste of space and discarded parts occurred when the function was not added. Furthermore, in the case of the discarding method, mounting / removing operations of mounted parts occur for LO grade and MID grade. In particular, it is necessary to use the Hi grade when one type of disposal method is supported, and the waste of scrapped parts and the increase in attachment / detachment work become remarkable.

本発明は上記状況に鑑みてなされたもので、その目的は、部品搭載空間の省スペース化が図れ、部品付捨ての無駄を排除でき、部品搭載性を向上させることができる車室環境用機能部品接続システムを提供することにある。 The present invention has been made in view of the above circumstances, and an object thereof is to save space for parts mounting space, to eliminate waste of parts disposal, and to improve the ability to mount parts, thereby improving the ability to mount parts. It is in providing a parts connection system.

本発明に係る上記目的は、下記構成により達成される。
（１）取付対象車両に共通して取り付けられる標準車室環境用機能部品を制御するための標準制御部と、前記標準制御部に接続される上位ハーネスと、前記上位ハーネスのうちの少なくとも通信線又は信号線に一端が分岐接続されるとともに、前記取付対象車両に選択的に後付けされる複数の拡張車室環境用機能部品に他端が接続される追加接続部材と、前記追加接続部材に設けられ前記標準制御部との相互通信によって前記拡張車室環境用機能部品を制御する拡張制御部と、を備え、前記複数の拡張車室環境用機能部品は、前記上位ハーネスに含まれる電源線から電力が供給される前記拡張車室環境用機能部品と、後付けされる場所に配索されている前記上位ハーネスとは別の電源線が分岐して接続されて前記別の電源線から電力が供給される前記拡張車室環境用機能部品と、を含むことを特徴とする車室環境用機能部品接続システム。 The above object of the present invention is achieved by the following constitution.
(1) A standard control unit for controlling a functional component for a standard cabin environment commonly attached to a target vehicle, an upper harness connected to the standard control unit, and at least a communication line of the upper harness Alternatively, an additional connection member whose one end is branch connected to the signal line and whose other end is connected to a plurality of extended compartment environmental functional components selectively retrofitted to the mounting target vehicle, and provided on the additional connection member An extended control unit for controlling the extended vehicle environment functional components by mutual communication with the standard control unit, the plurality of extended vehicle environment functional components being connected from the power supply line included in the upper level harness A power supply line separate from the functional component for the extended compartment environment to which power is supplied and the upper level harness wired to the place to be added is branched and connected to supply power from the other power supply line The A functional component connection system for a passenger compartment environment , comprising: the functional component for extended passenger compartment environment ;

上記（１）の構成の車室環境用機能部品接続システムによれば、取付対象車両に共通して取り付けられる上位ハーネスが共通化されると共に、取付対象車両に選択的に取り付けられる拡張車室環境用機能部品が、上位ハーネスのうちの少なくとも通信線又は信号線に一端が分岐接続される追加接続部材を介して後付けされる。そこで、上位ハーネスには、付捨てとなる構成部品が生じない。
更に、追加接続部材は、取付対象車両に選択的に後付けされる拡張車室環境用機能部品を上位ハーネスの任意の位置に追加接続可能である。この追加接続部材による拡張車室環境用機能部品の後付けは、車両用ハーネスの製造時は勿論、完成車両に配索された車両用ハーネスの上位ハーネスに対しても可能である。すなわち、ユーザー（車両購入者）が望む拡張車室環境用機能部品（オプション装備）の追加に応じて、複数の車両パターンに対応したワイヤハーネスを構成することが容易になる。勿論、その場合でも付捨てとなる構成部品（回路体等）が生じることはない。
また、追加接続部材は、取付対象車両に取り付けられる拡張車室環境用機能部品の数に応じて、上位ハーネスに対して分岐接続されるので、車両用ハーネス構造の全体に、付捨ての構成部品が発生しない。
また、従来の機能追加方式では、拡張車室環境用機能部品の増加により、拡張車室環境用機能部品が取り付けられる組合せ数に伴って、ワイヤハーネス全体の品番が増加した。これに対し、上記（１）の構成の車室環境用機能部品接続システムでは、車室環境用機能部品に対応する追加接続部材のみの品番を確保すればよい。これにより、製造部品の管理が容易となり、ワイヤハーネス製造コストの低減を図ることができる。
更に、追加接続部材が拡張制御部を備えることで、上位ハーネスに後付けされる車室環境用機能部品が拡張制御部を有していない場合でも、該車室環境用機能部品の機能向上が容易となる。
なお、上記拡張制御部が、例えばヒューズ機能を内蔵することにより、上位ハーネスへの直接接続や、複数の車室環境用機能部品の同時搭載が可能となる。これにより、機能後付け（所謂、「ポン付け」）や、上位ハーネス及び通信線又は信号線の系統数削減が可能となる。
更に、上記拡張制御部が、例えばマイクロコンピュータを内蔵することで、車室環境用機能部品のスイッチ入力、センサ入力、ＰＷＭ（Pulse Width Modulation）出力などの制御に対する対応が容易となる。これら車室環境用機能部品に対する制御は、マイクロコンピュータで行われるため、仕様変更等がソフトによって容易に対応が可能となる。
更に、後付けしようとする拡張車室環境用機能部品の直近に配索されている上位ハーネスが通信線や信号線のみであったり、上位ハーネスにおける電源線の電気容量が十分でなかったりした場合、拡張車室環境用機能部品の近傍に配索される他のハーネスの電源線に追加接続部材の電源線を分岐接続することで、拡張車室環境用機能部品の電源を簡便に得ることが可能となる。すなわち、拡張車室環境用機能部品用として、新たな電源線を上位ハーネスから配索する必要がなくなるので、電源線の系統削減が可能となる。 According to the functional component connection system for the passenger compartment environment of the configuration of (1), the upper harness commonly attached to the attachment target vehicle is made common, and the extended compartment environmental that is selectively attached to the attachment target vehicle The functional components are retrofitted via an additional connection member whose one end is branch-connected to at least a communication line or a signal line of the upper harness. Therefore, there is no component part to be discarded in the upper level harness.
Furthermore, the additional connection member can additionally connect the functional component for the extended cabin environment, which is selectively retrofitted to the mounting target vehicle, to any position of the upper harness. The retrofit of the extended compartment environment functional component by this additional connection member is possible not only at the time of manufacturing the vehicle harness but also for the upper harness of the vehicle harness wired in the completed vehicle. That is, it becomes easy to configure the wire harness corresponding to a plurality of vehicle patterns according to the addition of the extended compartment environment functional component (option equipment) desired by the user (vehicle purchaser). Of course, even in this case, no component (circuit body or the like) is thrown away.
In addition, since the additional connection member is branch-connected to the upper level harness according to the number of extended compartment environment functional components attached to the mounting target vehicle, the entire component of the vehicle harness structure can be discarded components Does not occur.
Further, in the conventional function addition method, the number of parts for the entire wire harness increases with the number of combinations in which the functional parts for the extended compartment environment are attached due to the increase of the functional parts for the extended compartment environment. On the other hand, in the vehicle interior environment functional component connection system of the configuration of the above (1), the product number of only the additional connection member corresponding to the vehicle interior environment functional component may be secured. As a result, management of the manufactured parts becomes easy, and the reduction of the wire harness manufacturing cost can be achieved.
Furthermore, by providing the expansion control unit as the additional connection member, even if the vehicle interior environment functional component retrofitted to the higher level harness does not have the expansion control unit, it is easy to improve the function of the vehicle interior environment functional component It becomes.
Note that, by incorporating the fuse function, for example, the expansion control unit enables direct connection to a host harness and simultaneous mounting of a plurality of vehicle interior environment functional components. This makes it possible to retrofit the function (so-called "pinning") and reduce the number of upper harnesses and the number of communication lines or signal lines.
Furthermore, the expansion control unit incorporates a microcomputer, for example, to facilitate control of control input such as switch input, sensor input, and PWM (Pulse Width Modulation) output of a functional component for a passenger compartment environment. Since control with respect to the functional components for the cabin environment is performed by the microcomputer, it is possible to easily cope with the change of the specification and the like by software.
Furthermore, if only the communication line or the signal line is the upper harness wired in the immediate vicinity of the extended compartment environment functional component to be retrofitted, or the electric capacity of the power supply line in the upper harness is insufficient, It is possible to easily obtain the power supply of the functional parts for the extended compartment environment by branching and connecting the power supply lines of the additional connection members to the power supply lines of other harnesses wired near the functional parts for the extended compartment environment It becomes. That is, since it is not necessary to arrange a new power supply line from the upper harness for the extended compartment environment functional component, it is possible to reduce the power supply line system.

（２）上記（１）の構成の車室環境用機能部品接続システムであって、前記上位ハーネスと前記追加接続部材とが、前記追加接続部材の導体に接続されて前記上位ハーネスの導体に圧接接続される圧接部と前記拡張制御部とを有するハーネス分岐接続機構により接続されることを特徴とする車室環境用機能部品接続システム。 (2) In the vehicle interior environment functional component connection system according to the above (1), the upper harness and the additional connection member are connected to the conductor of the additional connection member and pressure-welded to the conductor of the upper harness A vehicle environment environment functional component connection system characterized in that it is connected by a harness branch connection mechanism having a press-contact unit to be connected and the expansion control unit.

上記（２）の構成の車室環境用機能部品接続システムによれば、上位ハーネスと拡張車室環境用機能部品とを接続する追加接続部材が、上位ハーネスとの接続部分に、拡張制御部を有するハーネス分岐接続機構を備える。このハーネス分岐接続機構は、上位ハーネスに取り付けられることで、上位ハーネスのうちの少なくとも通信線又は信号線の導体を被覆した絶縁性の被覆部を圧接部によって切り裂き、この導体に圧接部を接続する。そこで、ハーネス分岐接続機構を上位ハーネスに取り付けるだけで、上位ハーネスと拡張車室環境用機能部品の接続が簡便に完了する。 According to the vehicle interior environment functional component connection system of the configuration of (2), the additional connection member for connecting the upper level harness and the extended compartment environmental function component is connected with the upper level harness at the connection portion with the upper level harness. It has a harness branch connection mechanism. The harness branching and connecting mechanism is attached to the upper harness, thereby tearing off the insulating covering portion covering at least the conductor of the communication wire or the signal wire of the upper harness by the pressure contact portion, and connecting the pressure contact portion to the conductor . Therefore, the connection of the upper harness and the functional component for the extended compartment environment is simply completed simply by attaching the harness branch connection mechanism to the upper harness.

本発明に係る車室環境用機能部品接続システムによれば、部品搭載空間の省スペース化が図れ、部品付捨ての無駄を排除でき、部品搭載性を向上させることができる。 According to the vehicle interior environment functional component connection system according to the present invention, space saving of component mounting space can be achieved, waste of component disposal can be eliminated, and component mountability can be improved.

以下、本発明に係る実施形態を図面を参照して説明する。
図１に示すように、本発明の一実施形態に係る車室環境用機能部品接続システムは、標準制御部１９と、上位ハーネス１１と、追加接続部材１３と、拡張制御部１５と、を主要な構成として有する。本実施形態において、車室環境用機能部品接続システムは、３種のグレード（ＬＯ、ＭＩＤ、Ｈｉ）に対応する例で説明する。なお、対応するグレードの種類はこれに限定されない。 Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the compartment environment functional component connection system according to the embodiment of the present invention mainly includes a standard control unit 19, an upper harness 11, an additional connection member 13, and an expansion control unit 15. As a configuration. In the present embodiment, the vehicle interior environment functional component connection system will be described as an example corresponding to three types of grades (LO, MID, Hi). In addition, the kind of corresponding grade is not limited to this.

本実施形態の車室環境用機能部品接続システムは、標準制御部１９が、取付対象車両に共通して取り付けられる標準車室環境用機能部品１７を制御する。以下、標準制御部１９を「エアコンディショナ（Ａ／Ｃ）用ＥＣＵ１９」と称す。車室環境用機能部品接続システムでは、このＡ／Ｃ用ＥＣＵ１９がマスターとなり、後述するオプションの拡張車室環境用機能部品の接続に用いられる拡張制御部１５がスレーブとなる。従って、Ａ／Ｃ用ＥＣＵ１９は、ＬＯグレード、ＭＩＤグレード、Ｈｉグレードに共通して一つのものが搭載される。 In the cabin environment functional component connection system of the present embodiment, the standard control unit 19 controls the standard cabin environmental functional components 17 that are commonly attached to the mounting target vehicle. Hereinafter, the standard control unit 19 will be referred to as "the ECU 19 for the air conditioner (A / C)". In the cabin environment functional component connection system, the A / C ECU 19 is a master, and the expansion control unit 15 used for connecting an optional extended cabin environmental functional component described later is a slave. Therefore, one A / C ECU 19 is mounted commonly to the LO grade, the MID grade, and the Hi grade.

車室環境用機能部品接続システムにおいて、ＬＯグレードのＡ／Ｃ用ＥＣＵ１９には、例えば日射センサ２１、Ａ／Ｃプレッシャセンサ２３、外気温センサ２５、ＥＣＯスイッチ２７、内気温センサ２９、ＰＴＣヒータ３１、ＭＧＣ３３、Ａ／Ｃコンプレッサー３５、ＤＥＦ３７、イオンジェネレータ３９までが標準車室環境用機能部品１７として接続される。 In the functional component connection system for a passenger compartment environment, for example, the solar radiation sensor 21, the A / C pressure sensor 23, the outside air temperature sensor 25, the ECO switch 27, the inside air temperature sensor 29, and the PTC heater 31 , The MGC 33, the A / C compressor 35, the DEF 37, and the ion generator 39 are connected as the functional component 17 for the standard cabin environment.

ＭＩＤグレードは、上記の標準車室環境用機能部品１７に加え、例えばフローセンサ４１、日射センサ４３、シートＨＴＲ４５、室内送風ブロア４７までが拡張車室環境用機能部品４９としてＡ／Ｃ用ＥＣＵ１９に接続される。 For the MID grade, in addition to the above-mentioned standard car interior environment functional parts 17, for example, the flow sensor 41, the solar radiation sensor 43, the seat HTR 45, and the indoor blowing blower 47 serve as the expansion car interior environment functional parts 49 to the A / C ECU 19. Connected

Ｈｉグレードは、ＬＯグレードの標準車室環境用機能部品１７とＭＩＤグレードの拡張車室環境用機能部品４９に加え、例えば温湿度センサ５１、排気センサ５３、リヤＡ／Ｃスイッチ５５、ＤＥＩＣＥＲ５７、送風シートＤ席５９、送風シートＰ席６１、シートヒータＤ席６３、シートヒータＰ席６５、リヤＡ／Ｃ６７におけるスモークセンサ６９、ブロアモータコントローラ７１、リヤブロアモータサブＡＳＳＹ７３、リヤマグネットバルブ７５、サーボモータ７７、Ｎｏ１クーラーサーミスタ７９までが拡張車室環境用機能部品４９としてＡ／Ｃ用ＥＣＵ１９に接続される。 Hi grade is, in addition to the functional parts 17 for standard car cabin environment of LO grade and the functional parts 49 for extended car cabin environment of MID grade, for example, temperature / humidity sensor 51, exhaust sensor 53, rear A / C switch 55, DEICER 57, air blower Seat D seat 59, blowing seat P seat 61, seat heater D seat 63, seat heater P seat 65, smoke sensor 69 in rear A / C 67, blower motor controller 71, rear blower motor subassembly 73, rear magnet valve 75, servo motor 77, The No. 1 cooler thermistor 79 is connected to the A / C ECU 19 as a functional component 49 for the extended cabin environment.

なお、上記車室環境用機能部品のうち、ＥＣＯスイッチ２７は、ドライバのエコ運転を支援し、燃費の向上に役立つＥＣＯモードへの切り替えを行う。ＰＴＣヒータ３１は、ＰＴＣ素子を利用したヒータであり、冷却水の温水を利用する通常の原動機の廃熱を利用できない車に使用される。ＭＧＣ３３は、内燃機関の回転をエアコンディショナに接続するための電磁クラッチである。ＤＥＩＣＥＲ５７は、フロントシールド下部を熱線であたため、フロントシールド下部にたまった雪を取り除きやすくするヒータである。 Among the functional components for the passenger compartment environment, the ECO switch 27 supports the driver's eco-driving and switches to the ECO mode to help improve the fuel consumption. The PTC heater 31 is a heater using a PTC element, and is used for a car that can not use the waste heat of a normal motor using hot water of cooling water. The MGC 33 is an electromagnetic clutch for connecting the rotation of the internal combustion engine to the air conditioner. The DEICER 57 is a heater that heats the lower part of the front shield, and thus makes it easy to remove snow accumulated on the lower part of the front shield.

Ａ／Ｃ用ＥＣＵ１９は、上位ハーネス１１と接続される。上位ハーネス１１は、電源線８１、通信線８３、ＧＮＤ８５（グランド線）の３種類の電線を基本とする電線束である。勿論、本発明における上位ハーネス１１は、電源線８１、通信線８３、ＧＮＤ８５の３種類に限るものではなく、信号線などの他の電線を含む形態を採り得ることは云うまでもない。 The A / C ECU 19 is connected to the upper level harness 11. The upper level harness 11 is a wire bundle based on three types of wires: a power supply wire 81, a communication wire 83, and a GND 85 (ground wire). Of course, the upper level harness 11 in the present invention is not limited to the three types of the power supply line 81, the communication line 83, and the GND 85, and it is needless to say that another form such as a signal line may be adopted.

拡張車室環境用機能部品４９は、追加接続部材１３を介して上位ハーネス１１に「後付け」されている。つまり、拡張車室環境用機能部品４９は、この追加接続部材１３及び上位ハーネス１１を介してＡ／Ｃ用ＥＣＵ１９と接続される。 The extended compartment environment functional component 49 is “post-attached” to the upper harness 11 via the additional connection member 13. That is, the extended compartment environment functional component 49 is connected to the A / C ECU 19 via the additional connection member 13 and the upper harness 11.

追加接続部材１３は、上位ハーネス１１における電源線８１、通信線８３及びＧＮＤ８５に分岐接続するためのハーネス分岐接続機構が一端に設けられる。拡張制御部１５は、このハーネス分岐接続機構に設けられている。以下、拡張制御部１５を有するハーネス分岐接続機構をＥコネクタ８７と称する。追加接続部材１３は、取付対象車両に選択的に後付けされる拡張車室環境用機能部品４９に接続するための補機接続機構８９が他端に設けられている。 The additional connection member 13 is provided with a harness branch connection mechanism at one end for branch connection to the power supply line 81, the communication line 83, and the GND 85 in the upper level harness 11. The expansion control unit 15 is provided in the harness branch connection mechanism. The harness branch connection mechanism having the expansion control unit 15 is hereinafter referred to as an E connector 87. The additional connection member 13 is provided at its other end with an accessory connection mechanism 89 for connecting to a functional component 49 for extended compartment environment that is selectively retrofitted to the mounting target vehicle.

更に詳しくは、図２の（ａ）に示すように、追加接続部材１３は、追加ハーネス９１と、追加ハーネス９１の上位ハーネス側端でＥコネクタ８７に接続される上位ハーネス側コネクタ９３と、追加ハーネス９１の補機装置側端で拡張車室環境用機能部品４９に接続される補機側コネクタ９５とを有する。そして、追加接続部材１３は、補機側コネクタ９５が、拡張車室環境用機能部品４９に設けられたコネクタ９７と共に構成する補機接続機構８９に接続され、上位ハーネス側コネクタ９３が、Ｅコネクタ８７の基板実装コネクタ９９に接続されている。
すなわち、本実施形態の追加接続部材１３は、所望の長さを有するシンプルな構造の追加ハーネス９１を介して上位ハーネス１１と拡張車室環境用機能部品４９とを接続することができるので、拡張車室環境用機能部品４９の位置に合わせた搭載が可能となり、高い汎用性を得ることができる。 More specifically, as shown in FIG. 2A, the additional connection member 13 includes an additional harness 91, an upper harness connector 93 connected to the E connector 87 at the upper harness side end of the additional harness 91, and And an accessory-side connector 95 connected to the extended compartment environment functional component 49 at the accessory device side end of the harness 91. Then, the additional connection member 13 is connected to the accessory connection mechanism 89 configured with the accessory-side connector 95 together with the connector 97 provided to the extended compartment environment functional component 49, and the upper harness side connector 93 is an E connector It is connected to 87 board mounted connectors 99.
That is, since the additional connection member 13 of the present embodiment can connect the upper harness 11 and the functional component 49 for the extended compartment environment via the additional harness 91 having a simple structure having a desired length, the expansion is performed. The mounting according to the position of the functional component 49 for the passenger compartment environment becomes possible, and high versatility can be obtained.

なお、本発明に係る追加接続部材１３の形態は、上記実施形態の追加接続部材１３に限定されるものではなく、種々の形態を採りえる。
例えば、図２の（ｂ）に示す追加接続部材１０１は、追加ハーネス９１の上位ハーネス側端が、Ｅコネクタ８７の拡張制御部１５に直接接続され、補機側コネクタ９５が、拡張車室環境用機能部品４９のコネクタ９７にコネクタ接続されている。 In addition, the form of the additional connection member 13 which concerns on this invention is not limited to the additional connection member 13 of the said embodiment, A various form can be taken.
For example, in the additional connection member 101 shown in FIG. 2B, the upper harness side end of the additional harness 91 is directly connected to the expansion control unit 15 of the E connector 87, and the accessory side connector 95 is an expansion compartment environment. The connector 97 is connected to the connector 97 of the functional component 49.

また、図２の（ｃ）に示す追加接続部材１０３は、追加ハーネス９１の上位ハーネス側端が、Ｅコネクタ８７の拡張制御部１５に直接接続されると共に、追加ハーネス９１の補機装置側端が、拡張車室環境用機能部品４９の回路に直接接続されて、拡張車室環境用機能部品４９と一体に構成されている。勿論、追加ハーネス９１の上位ハーネス側端に設けた上位ハーネス側コネクタ９３が、Ｅコネクタ８７の基板実装コネクタ９９に接続される構成とすることもできる（図２の（ａ）参照）。なお、追加ハーネス９１は、下位電源線１０５と、下位ＧＮＤ１０７と、からなる。 Further, in the additional connection member 103 shown in FIG. 2C, the upper harness side end of the additional harness 91 is directly connected to the expansion control unit 15 of the E connector 87 and the auxiliary device side end of the additional harness 91 However, it is directly connected to the circuit of the extended compartment environmental functional component 49 and is integrally configured with the extended compartment environmental functional component 49. Of course, the upper harness side connector 93 provided at the upper harness side end of the additional harness 91 may be connected to the board mounted connector 99 of the E connector 87 (see FIG. 2A). The additional harness 91 is composed of the lower power supply line 105 and the lower GND 107.

ここで、拡張車室環境用機能部品４９が各種センサの場合は、センサ電源線、センサ信号線及びセンサＧＮＤを含む追加ハーネスにより上位ハーネス１１に接続される。また、拡張車室環境用機能部品４９が各種スイッチの場合は、スイッチの接続数に応じたスイッチ信号線である追加ハーネスにより上位ハーネス１１に接続される。 Here, when the extended compartment environment functional component 49 is any of various sensors, it is connected to the upper level harness 11 by the additional harness including the sensor power supply line, the sensor signal line, and the sensor GND. When the extended compartment environment functional component 49 is any of various switches, it is connected to the upper level harness 11 by an additional harness which is a switch signal line corresponding to the number of switches connected.

図３の（ａ）〜（ｃ）に示すように、Ｅコネクタ８７は、追加接続部材１３の導体に接続されて上位ハーネス１１の導体に圧接接続される圧接部１０９を有する。圧接部１０９は、例えば一対からなる複数の圧接刃１１１を起立して構成され、回路基板１１３の所定の回路に接続される。回路基板１１３は、上ケース１１５と下ケース１１７とによって構成された絶縁樹脂製のケース内に収容される。上ケース１１５及び下ケース１１７は、例えば薄肉ヒンジ（図示略）によって開閉自在に連結される。 As shown in (a) to (c) of FIG. 3, the E-connector 87 has a pressure contact portion 109 connected to the conductor of the additional connection member 13 and pressure connected to the conductor of the upper harness 11. The pressure-contacting portion 109 is configured by, for example, raising a plurality of pressure-contacting blades 111 consisting of a pair, and is connected to a predetermined circuit of the circuit board 113. The circuit board 113 is accommodated in a case made of an insulating resin formed of an upper case 115 and a lower case 117. The upper case 115 and the lower case 117 are openably connected by, for example, a thin hinge (not shown).

Ｅコネクタ８７は、上ケース１１５及び下ケース１１７によって上位ハーネス１１における電源線８１、通信線８３及びＧＮＤ８５を挟み込むことで、各線の絶縁被覆を圧接刃１１１が切り裂き、各線の導体に圧接部１０９が圧接接続される。上位ハーネス１１における電源線８１、通信線８３及びＧＮＤ８５を挟んだＥコネクタ８７は、上ケース１１５及び下ケース１１７がロックされることで、上位ハーネス１１の任意位置に固定される。すなわち、本実施形態に係る車室環境用機能部品接続システムによれば、Ｅコネクタ８７を上位ハーネス１１の任意の位置に取り付けるだけで、上位ハーネス１１と拡張車室環境用機能部品４９の接続が簡便に完了する。なお、拡張車室環境用機能部品４９のＧＮＤ８５がボディアースされる場合には、上位ハーネス１１におけるＧＮＤ８５の追加接続部材１３による分岐接続は必ずしも必要ではない。分岐接続が必要な場合とは、例えば、Ｅコネクタ８７を製造検査等により単体で動かす必要がある場合である。 In the E connector 87, by sandwiching the power supply line 81, the communication line 83 and the GND 85 in the upper harness 11 by the upper case 115 and the lower case 117, the press contact blade 111 cuts and tears the insulation coating of each line, and the press contact portion 109 Press-connected. The E connector 87 sandwiching the power supply line 81, the communication line 83 and the GND 85 in the upper harness 11 is fixed to an arbitrary position of the upper harness 11 by the upper case 115 and the lower case 117 being locked. That is, according to the vehicle interior environment functional component connection system according to the present embodiment, the connection between the upper level harness 11 and the extended compartment environmental functional component 49 is obtained simply by attaching the E connector 87 to any position of the upper level harness 11. Easy to complete. When the GND 85 of the extended compartment environment functional component 49 is body-grounded, the branch connection by the additional connection member 13 of the GND 85 in the upper level harness 11 is not necessarily required. The case where the branch connection is required is, for example, the case where it is necessary to move the E connector 87 alone by manufacturing inspection or the like.

本実施形態に係るＥコネクタ８７の回路基板１１３には、上記の拡張制御部１５が設けられている。上位ハーネス１１や拡張制御部１５と接続されたＥコネクタ８７の回路は、回路基板１１３に設けられた基板実装コネクタ９９によって外部へ取り出される。 The above-described expansion control unit 15 is provided on the circuit board 113 of the E connector 87 according to the present embodiment. The circuit of the E connector 87 connected to the upper level harness 11 and the expansion control unit 15 is taken out to the outside by the board mounted connector 99 provided on the circuit board 113.

本実施形態の車室環境用機能部品接続システムは、上記したように、Ａ／Ｃ用ＥＣＵ１９がマスターとなり、拡張制御部１５がスレーブとなる。
従来は、一つのＥＣＵが複数個の負荷に対する制御を集中的に行っていた。しかし、この場合、ＥＣＵに負担が集中する。そこで、本実施形態の車室環境用機能部品接続システムでは、追加接続部材１３に拡張制御部１５を設け、Ａ／Ｃ用ＥＣＵ１９とこの拡張制御部１５とによって制御を分散させている。 As described above, in the compartment environment functional component connection system of the present embodiment, the A / C ECU 19 is a master, and the expansion control unit 15 is a slave.
Conventionally, one ECU intensively performs control for a plurality of loads. However, in this case, the load is concentrated on the ECU. Therefore, in the compartment environment functional component connection system of the present embodiment, the additional connection member 13 is provided with the expansion control unit 15, and the control is dispersed by the A / C ECU 19 and the expansion control unit 15.

拡張制御部１５は、マイクロコンピュータを備え、他の制御部と通信する機能を有する。すなわち、拡張制御部１５は、通信によりＡ／Ｃ用ＥＣＵ１９から受け取った制御信号に従って、負荷を制御する。また、拡張制御部１５は、スイッチや、センサの状態を表す信号を通信によりＡ／Ｃ用ＥＣＵ１９に送信する。 The extension control unit 15 includes a microcomputer and has a function of communicating with other control units. That is, the extension control unit 15 controls the load in accordance with the control signal received from the A / C ECU 19 by communication. Further, the extension control unit 15 transmits a signal indicating a state of a switch or a sensor to the A / C ECU 19 by communication.

図４に示すように、拡張制御部１５は、マイクロコンピュータ１１９、電源部１２１、ドライバ１２３、有線通信インタフェース１２５、及び信号処理回路１２７を内蔵している。拡張制御部１５は、追加接続部材１３によって例えば負荷１２９、スイッチ１３１、センサ１３３に接続される。実際に拡張制御部１５が接続される負荷１２９、スイッチ１３１、センサ１３３の各々の有無及び数については、必要に応じて変更される。 As shown in FIG. 4, the expansion control unit 15 incorporates a microcomputer 119, a power supply unit 121, a driver 123, a wired communication interface 125, and a signal processing circuit 127. The expansion control unit 15 is connected to, for example, the load 129, the switch 131, and the sensor 133 by the additional connection member 13. The presence and the number of each of the load 129, the switch 131, and the sensor 133 to which the expansion control unit 15 is actually connected are changed as necessary.

上位ハーネス１１は、例えば幹線ハーネスから分岐される。車両上主電源１３５が供給する電源電力（例えば＋１２Ｖ）は、電源分配ボックス１３７の内部で複数系統に分配され、電源分配ボックス１３７の配下に接続された幹線ワイヤハーネス１３９に供給される。 The upper level harness 11 is branched from, for example, a main line harness. The power supply power (for example, +12 V) supplied by the on-vehicle main power supply 135 is distributed to a plurality of systems in the power supply distribution box 137 and supplied to the trunk wire harness 139 connected under the power supply distribution box 137.

スイッチ１３１は、例えばユーザの操作に応じてオンオフする電気信号を出力する。センサ１３３は、様々な計測値や、状態などを表す電気信号を出力する。信号処理回路１２７は、スイッチ１３１及びセンサ１３３が出力する電気信号を例えば定期的に処理して、データ通信に適した情報を生成する。 The switch 131 outputs, for example, an electrical signal that is turned on and off in response to a user operation. The sensor 133 outputs electrical signals representing various measurement values, states, and the like. The signal processing circuit 127 periodically processes, for example, the electrical signals output from the switch 131 and the sensor 133 to generate information suitable for data communication.

負荷１２９の具体例としては、上記の拡張車室環境用機能部品４９が挙げられる。拡張制御部１５は、負荷１２９に通電することにより、これを駆動することができる。拡張制御部１５は、負荷１２９の通電を制御するためにドライバ１２３が備わっている。ドライバ１２３は、例えばトランジスタのようなスイッチング素子を内蔵し、制御信号に従って負荷１２９の通電のオンオフや通電のデューティ制御を行うことができる。 As a specific example of the load 129, the above-mentioned functional component 49 for the extended compartment environment can be mentioned. The expansion control unit 15 can drive the load 129 by energizing it. The expansion control unit 15 is provided with a driver 123 for controlling the energization of the load 129. The driver 123 incorporates, for example, a switching element such as a transistor, and can perform on / off control of the energization of the load 129 and duty control of the energization according to the control signal.

すなわち、ドライバ１２３のスイッチング素子がオンになった時に、電源線８１に供給される電源電力が、電源部１２１、ドライバ１２３を経由して負荷１２９に供給される。負荷１２９を制御するための制御信号は、Ａ／Ｃ用ＥＣＵ１９からの指示によってマイクロコンピュータ１１９から出力され、ドライバ１２３に入力される。 That is, when the switching element of the driver 123 is turned on, the power supply power supplied to the power supply line 81 is supplied to the load 129 via the power supply unit 121 and the driver 123. A control signal for controlling the load 129 is output from the microcomputer 119 according to an instruction from the A / C ECU 19, and is input to the driver 123.

有線通信インタフェース１２５は、通信線８３を経由して、Ａ／Ｃ用ＥＣＵ１９との間のデータ通信経路を確立する。また、有線通信インタフェース１２５は、Ａ／Ｃ用ＥＣＵ１９が出力する制御信号を受信してドライバ１２３に与える。また、信号処理回路１２７が出力する様々な情報をデータ通信によりＡ／Ｃ用ＥＣＵ１９に送信する。なお、図４においては、データをコード化された信号に変換するエンコーダ、及びコード化された信号を読んで元のデータに変換するデコーダを省略している。 The wired communication interface 125 establishes a data communication path with the A / C ECU 19 via the communication line 83. Further, the wired communication interface 125 receives a control signal output from the A / C ECU 19 and supplies the control signal to the driver 123. Further, various information output from the signal processing circuit 127 is transmitted to the A / C ECU 19 by data communication. In FIG. 4, an encoder for converting data to a coded signal and a decoder for reading the coded signal and converting them to original data are omitted.

本実施形態の車室環境用機能部品接続システムでは、データ通信の方式として、例えばシリアル通信を行うことができる。シリアル通信は、一つの情報をビットごとに分けて送って１種類の情報とする。シリアル通信は、時間的に、順番にビットデータを送ることとなるので、通信速度はパラレル通信よりも遅くなるが、通信線８３を１本とすることができる。シリアル通信は、時間的に「１」と「０」のパルス信号が順に並んだものとなる。一つの情報の識別は、伝送データの終端をハイレベルの「１」とし、始端をローレベルの「０」として行う。このようにして、車室環境用機能部品接続システムでは、同じ通信線８３の上で複数の信号を多重通信可能としている。 In the vehicle interior environment functional component connection system of the present embodiment, for example, serial communication can be performed as a data communication method. In serial communication, one piece of information is divided into bits and sent as one type of information. Since serial communication sequentially sends bit data in time, the communication speed is slower than parallel communication, but one communication line 83 can be used. In serial communication, pulse signals of "1" and "0" are sequentially arranged in time. In the identification of one piece of information, the end of transmission data is set to high level "1", and the start end is set to low level "0". In this manner, in the compartment environment functional component connection system, multiple signals can be multiplexed and communicated on the same communication line 83.

本実施形態の車室環境用機能部品接続システムでは、拡張制御部１５をノードと考えることができる。ノードとノードとを結ぶ信号伝送回路の接続形態（トポロジー）として、車室環境用機能部品接続システムでは、バス形式を用いている。バス形式は、１本の通信線８３（バス）に並列に複数のノードが接続される。このバス形式では、一つのノードからすべてのノードに同時に通信の呼びかけができる。この他、車室環境用機能部品接続システムの信号伝送回路の接続形態としては、リング形式やスター形式が用いられてもよい。 In the compartment environment functional component connection system according to the present embodiment, the expansion control unit 15 can be considered as a node. As a connection form (topology) of signal transmission circuits connecting nodes and nodes, a bus type is used in a functional component connection system for a passenger compartment environment. In the bus type, a plurality of nodes are connected in parallel to one communication line 83 (bus). In this bus format, one node can call all nodes simultaneously for communication. In addition, as a connection form of the signal transmission circuit of the functional component connection system for a passenger compartment environment, a ring form or a star form may be used.

次に、本発明に係る車室環境用機能部品接続システムの変形例を説明する。
図５に示すように、変形例に係る追加接続部材１４１は、追加電源線１４３、追加ＧＮＤ１４５及び追加信号線１４７を有する追加ハーネス１４９と、追加ハーネス１４９の拡張車室環境用機能部品側端に接続される拡張車室環境用機能部品側コネクタ１５１と、追加信号線１４７の上位ハーネス側端に接続されるＥコネクタ８７と、を備える。
そして、追加ハーネス１４９の拡張車室環境用機能部品側コネクタ１５１が、オンオフの信号を受けてスイッチングするスイッチ機能部１５３を備えた拡張車室環境用機能部品４９の機器コネクタ１５７にコネクタ接続される。また、追加ハーネス１４９における追加信号線１４７の一端がＥコネクタ８７を介して上位ハーネス１１の信号線１５９に分岐接続され、追加電源線１４３の一端が上位ハーネス１１とは別の他のハーネス１６１における電源線８１Ａに圧接ジョイント１６３を介して分岐接続され、追加ハーネス１４９における追加ＧＮＤ１４５の一端がボディアースされている。 Next, a modification of the compartment environment functional component connection system according to the present invention will be described.
As shown in FIG. 5, the additional connection member 141 according to the modification includes the additional harness 149 having the additional power supply line 143, the additional GND 145 and the additional signal line 147, and the functional component side of the additional harness 149 for the expanded cabin environment. An extended compartment environment functional component side connector 151 to be connected and an E connector 87 connected to the upper harness side end of the additional signal line 147 are provided.
Then, the extension compartment environment functional component side connector 151 of the additional harness 149 is connected to the equipment connector 157 of the extension compartment environment functional component 49 provided with the switch function unit 153 that receives and switches the on / off signal. . Further, one end of the additional signal line 147 in the additional harness 149 is branched and connected to the signal line 159 of the upper harness 11 via the E connector 87, and one end of the additional power line 143 is in another harness 161 different from the upper harness 11. A branch connection is made to the power supply wire 81A via the pressure-welding joint 163, and one end of the additional GND 145 in the additional harness 149 is body-grounded.

また、図６に示すように、他の変形例に係る追加接続部材１６５は、追加電源線１４３、追加通信線１６７及び追加ＧＮＤ１４５を有する追加ハーネス１６９と、追加ハーネス１６９の拡張車室環境用機能部品側端に接続される拡張車室環境用機能部品側コネクタ１７１と、追加通信線１６７の上位ハーネス側端に接続されるハーネス分岐接続機構１７３と、を備える。そして、拡張車室環境用機能部品４９にコネクタ接続される拡張車室環境用機能部品側コネクタ１７１には、拡張制御部１５が設けられている。また、追加ハーネス１６９における追加通信線１６７の一端がハーネス分岐接続機構１７３を介して上位ハーネス１１の通信線８３に分岐接続され、追加電源線１４３の一端が上位ハーネス１１とは別の他のハーネス１６１における電源線８１Ａに圧接ジョイント１６３を介して分岐接続され、追加ハーネス１６９における追加ＧＮＤ１４５の一端がボディアースされている。 Further, as shown in FIG. 6, the additional connection member 165 according to the other modification includes the additional harness 169 having the additional power supply line 143, the additional communication line 167, and the additional GND 145, and the function for the extended compartment environment of the additional harness 169. An extended compartment environment functional component side connector 171 connected to the component side end and a harness branch connecting mechanism 173 connected to the upper harness side end of the additional communication line 167 are provided. Further, the extended control unit 15 is provided in the extended compartment environmental functional component side connector 171 connected to the extended compartment environmental functional component 49 by a connector. Further, one end of the additional communication line 167 in the additional harness 169 is branched and connected to the communication line 83 of the upper harness 11 via the harness branch / connection mechanism 173, and one end of the additional power line 143 is another harness different from the upper harness 11. A branch connection is made to the power supply line 81A at 161 via a pressure welding joint 163, and one end of the additional GND 145 in the additional harness 169 is body-grounded.

すなわち、図５及び図６に示したように、後付けしようとする拡張車室環境用機能部品４９の直近に配索されている上位ハーネス１１が信号線１５９又は通信線８３のみであったり、上位ハーネス１１における電源線８１の電気容量が十分でなかったりすると、上位ハーネス１１から拡張車室環境用機能部品４９に電源の供給が行えない場合がある。このような場合、追加接続部材１４１又は追加接続部材１６５によって、拡張車室環境用機能部品４９の近傍に配索される他のハーネス１６１の電源線８１Ａに追加電源線１４３を分岐接続することで、拡張車室環境用機能部品４９の電源を簡便に得ることが可能となる。 That is, as shown in FIG. 5 and FIG. 6, the upper harness 11 routed immediately before the extended compartment environment functional component 49 to be retrofitted is only the signal line 159 or the communication line 83, or the upper harness 11 If the electrical capacity of the power supply line 81 in the harness 11 is not sufficient, power may not be supplied from the upper level harness 11 to the functional component 49 for the extended cabin environment. In such a case, the additional power supply line 143 is branched and connected to the power supply line 81A of the other harness 161 wired in the vicinity of the functional component 49 for the extended compartment environment by the additional connection member 141 or the additional connection member 165. The power supply of the functional component 49 for the extended compartment environment can be easily obtained.

次に、上記の車室環境用機能部品接続システムの作用を説明する。
本実施形態に係る車室環境用機能部品接続システムでは、取付対象車両に共通して取り付けられる上位ハーネス１１が共通化されると共に、取付対象車両に選択的に取り付けられる拡張車室環境用機能部品４９が、上位ハーネス１１のうちの少なくとも通信線８３又は信号線１５９に一端が分岐接続される追加接続部材１３を介して後付けされる。そこで、上位ハーネス１１には、付捨てとなる構成部品が生じない。 Next, the operation of the above-described functional component connection system for the passenger compartment environment will be described.
In the vehicle interior environment functional component connection system according to the present embodiment, the upper harness 11 attached in common to the attachment target vehicle is made common, and the extended compartment environmental functional components selectively attached to the attachment target vehicle 49 is retrofitted to at least the communication line 83 or the signal line 159 of the upper level harness 11 via the additional connection member 13 whose one end is branched and connected. Therefore, there is no component part to be discarded in the upper level harness 11.

更に、追加接続部材１３は、取付対象車両に選択的に後付けされる拡張車室環境用機能部品４９を上位ハーネス１１の任意の位置に追加接続可能である。この追加接続部材１３による拡張車室環境用機能部品４９の後付けは、車両用ハーネスの製造時は勿論、完成車両に配索された車両用ハーネスの上位ハーネス１１に対しても可能である。すなわち、ユーザー（車両購入者）が望む拡張車室環境用機能部品４９（オプション装備）の追加に応じて、複数の車両パターンに対応したワイヤハーネスを構成することが容易になる。勿論、その場合でも付捨てとなる構成部品（回路体等）が生じることはない。 Furthermore, the additional connection member 13 can additionally connect the extended compartment environment functional component 49 selectively retrofitted to the mounting target vehicle at an arbitrary position of the upper harness 11. The retrofit of the extended compartment environment functional component 49 by the additional connection member 13 is possible not only at the time of manufacturing the vehicle harness but also for the upper harness 11 of the vehicle harness wired in the completed vehicle. That is, in accordance with the addition of the functional component 49 (option equipment) for the extended compartment environment desired by the user (vehicle purchaser), it becomes easy to configure a wire harness corresponding to a plurality of vehicle patterns. Of course, even in this case, no component (circuit body or the like) is thrown away.

また、追加接続部材１３は、取付対象車両に取り付けられる拡張車室環境用機能部品４９の数に応じて、上位ハーネス１１に対して分岐接続されるので、車両用ハーネス構造の全体に、付捨ての構成部品が発生しない。
また、従来の機能追加方式では、拡張車室環境用機能部品４９の増加により、拡張車室環境用機能部品４９が取り付けられる組合せ数に伴って、ワイヤハーネス全体の品番が増加した。これに対し、本実施形態の車室環境用機能部品接続システムでは、拡張車室環境用機能部品４９に対応する追加接続部材１３のみの品番を確保すればよい。これにより、製造部品の管理が容易となり、ワイヤハーネス製造コストの低減を図ることができる。 Further, since the additional connection member 13 is branch-connected to the upper level harness 11 according to the number of the extended compartment environment functional components 49 attached to the mounting target vehicle, the additional connection member 13 is discarded to the entire vehicle harness structure. Does not generate component parts of
Further, in the conventional function addition method, the number of parts of the entire wire harness increases with the number of combinations in which the extended compartment environmental functional parts 49 are attached due to the increase of the functional parts 49 for extended compartment environment. On the other hand, in the compartment environment functional component connection system according to the present embodiment, the product number of only the additional connection member 13 corresponding to the extended compartment environmental functional component 49 may be secured. As a result, management of the manufactured parts becomes easy, and the reduction of the wire harness manufacturing cost can be achieved.

更に、追加接続部材１３が拡張制御部１５を備えることで、上位ハーネス１１に後付けされる拡張車室環境用機能部品４９が拡張制御部１５を有していない場合でも、該拡張車室環境用機能部品４９の機能向上が容易となる。
なお、上記の拡張制御部１５が、例えばヒューズ機能を内蔵することにより、上位ハーネス１１への直接接続や、複数の拡張車室環境用機能部品４９の同時搭載が可能となる。これにより、機能後付け（所謂、「ポン付け」）や、上位ハーネス１１及び通信線８３又は信号線１５９の系統数削減が可能となる。
更に、上記の拡張制御部１５が、マイクロコンピュータ１１９を内蔵することで、拡張車室環境用機能部品４９のスイッチ入力、センサ入力、ＰＷＭ（Pulse Width Modulation）出力などの制御に対する対応が容易となる。これら拡張車室環境用機能部品４９に対する制御は、マイクロコンピュータ１１９で行われるため、仕様変更等がソフトによって容易に対応が可能となる。 Furthermore, by providing the expansion control unit 15 for the additional connection member 13, even if the expansion compartment environment functional component 49 to be added to the higher level harness 11 does not have the expansion control unit 15, the expansion compartment environment function is The functional improvement of the functional component 49 is facilitated.
Note that, by incorporating the fuse function, for example, the above-mentioned extension control unit 15 enables direct connection to the upper level harness 11 and simultaneous mounting of a plurality of extended compartment environmental functional components 49. As a result, it is possible to add functions (so-called "pinning") and to reduce the number of systems of the upper harness 11 and the communication line 83 or the signal line 159.
Furthermore, the above-mentioned extended control unit 15 incorporates the microcomputer 119, which makes it easy to cope with control of the switch input, sensor input, PWM (Pulse Width Modulation) output, etc. of the functional component 49 for extended cabin environment. . The control of these extended compartment environment functional components 49 is performed by the microcomputer 119, so that changes in specifications and the like can be easily handled by software.

また、本実施形態の車室環境用機能部品接続システムでは、上位ハーネス１１と拡張車室環境用機能部品４９とを接続する追加接続部材１３が、上位ハーネス１１との接続部分に、拡張制御部１５を有するＥコネクタ８７を備える。このハーネス分岐接続機構としてのＥコネクタ８７は、上位ハーネス１１に取り付けられることで、上位ハーネス１１のうちの少なくとも通信線８３又は信号線１５９の導体を被覆した絶縁性の被覆部を圧接部１０９によって切り裂き、この導体に圧接部１０９を接続する。そこで、Ｅコネクタ８７を上位ハーネス１１に取り付けるだけで、上位ハーネス１１と拡張車室環境用機能部品４９の接続が簡便に完了する。 In addition, in the vehicle interior environment functional component connection system according to the present embodiment, the additional connection member 13 connecting the upper level harness 11 and the extended compartment environmental function component 49 is connected to the upper level harness 11 as an extension control unit. An E connector 87 having 15 is provided. The E connector 87 as the harness branch connection mechanism is attached to the upper harness 11 so that the insulation covering portion covering the conductor of at least the communication wire 83 or the signal wire 159 in the upper harness 11 is made by the pressure contact portion 109. The pressure contact portion 109 is connected to this conductor. Therefore, simply by attaching the E connector 87 to the upper harness 11, the connection between the upper harness 11 and the functional component 49 for extended cabin environment is completed simply.

更に、本実施形態の車室環境用機能部品接続システムでは、後付けしようとする拡張車室環境用機能部品４９の直近に配索されている上位ハーネス１１が通信線８３や信号線１５９のみであったり、上位ハーネス１１における電源線８１の電気容量が十分でなかったりした場合、拡張車室環境用機能部品４９の近傍に配索される他のハーネス１６１の電源線８１Ａに追加接続部材１４１又は追加接続部材１６５の追加電源線１４３を分岐接続することで、拡張車室環境用機能部品４９の電源を簡便に得ることが可能となる。すなわち、拡張車室環境用機能部品用として、新たな電源線８１を上位ハーネス１１から配索する必要がなくなるので、電源線８１の系統削減が可能となる。 Furthermore, in the vehicle interior environment functional component connection system of the present embodiment, only the communication line 83 and the signal line 159 are the upper level harness 11 wired immediately before the extended cabin environmental functional component 49 to be retrofitted. If the electric capacity of the power supply line 81 in the upper level harness 11 is not sufficient, the additional connection member 141 or the addition to the power supply line 81A of the other harness 161 wired in the vicinity of the extended compartment environment functional component 49 By branching and connecting the additional power supply line 143 of the connection member 165, it is possible to easily obtain the power supply of the functional component 49 for the extended compartment environment. That is, since it is not necessary to arrange a new power supply line 81 from the upper level harness 11 for the extended compartment environment functional component, it is possible to reduce the number of power supply lines 81.

従って、上記実施形態に係る車室環境用機能部品接続システムによれば、部品搭載空間の省スペース化が図れ、部品付捨ての無駄を排除でき、部品搭載性を向上させることができる。 Therefore, according to the functional component connection system for a passenger compartment environment according to the above-described embodiment, space saving of component mounting space can be achieved, waste of component disposal can be eliminated, and component mountability can be improved.
