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 vehicle component environment functional component connection system.

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 respond to the presence or absence of functions due to differences in specifications (grades). In particular, the number of functional parts related to the control of the cabin environment such as an air conditioner (A / C) increases as the grade (LO, MID, Hi) increases.
As functional parts related to the 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, seat HTR 525, indoor blower 527, temperature / 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 ASSY 551, rear magnet Tobarubu 553, servo motor 555, No1 cooler thermistor 557, and the like. Hereinafter, in the present specification, these functional components are referred to as “functional components for vehicle interior environment”. These compartment environmental functional parts 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）。 Further, 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 “ECU (Electronic Control Unit)”) for controlling each vehicle electrical component are respectively provided. A vehicle network system is used which is connected by a common multiplex communication line, transmits / receives multiplexed signals through the multiplex communication line, and controls the operation of each vehicle electrical component based on this signal. (For example, refer to 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。 The assembly of the conventional functional parts for the passenger compartment environment is different for each grade (LO, MID, Hi), three different types of A / C ECU-LO559, A / C ECU-MID561, and A / C ECU-Hi563) was connected by a wire harness. As for the wire harness routed in the vehicle, for example, a plurality of circuit-specific sub-harnesses that are sub-divided for each system circuit are combined to form a whole wire harness. The system circuit includes, for example, a standard circuit including LO grade vehicle compartment environment functional components such as a solar radiation sensor 501 and an A / C pressure sensor 503, an exhaust sensor 531, a rear A / C switch 533, and the like. Thus, there is an optional circuit including a functional component for Hi-grade vehicle compartment environment. And when manufacturing such a wire harness for motor vehicles, each is determined so that the whole wire harness may become suitable, considering arrangement | positioning 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 function additions so far have been broadly divided into a correspondence method according to specifications, a discard method, and a combination of these methods.
However, the correspondence method by specification requires three types of A / C ECU-LO559, A / C ECU-MID561, and A / C ECU-Hi563, and in addition to this, an ECU (driver) or There was a problem that the variation of the power distribution box increased.
In addition, since the discarding method is provided with functions to be added in advance in the ECU (driver) or the power distribution box, a space when the function is not added and a waste of discarded parts are generated. Further, in the case of the discarding method, a mounting / dismounting operation of the mounted parts occurs for the LO grade and the MID grade. In particular, when one type of disposal method is used, it is necessary to use the Hi grade, and waste of discarded components and an increase in the attaching / detaching operations 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 situation, and its purpose is to reduce the space for mounting components, eliminate waste of discarding components, and improve the component mounting capability. It is to provide a component 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少なくとも１つ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、を備える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 configuration.
(1) A standard control unit for controlling a functional component for a standard vehicle compartment environment that is commonly mounted on a vehicle to be mounted, 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 branched and connected to the signal line, and whose other end is connected to at least one extended compartment environment functional component selectively attached to the attachment target vehicle, and the additional connection member A vehicle compartment environment functional component connection system comprising: an expansion control unit that is provided and controls the functional component for extended vehicle cabin environment through mutual communication with the standard control unit.

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。 According to the functional component connection system for a vehicle compartment environment configured as described in (1) above, an upper vehicle harness that is commonly attached to a vehicle to be attached is shared, and an extended vehicle compartment environment that is selectively attached to the vehicle to be attached. The functional component is retrofitted via an additional connection member having one end branched and connected to at least the communication line or the signal line of the upper harness. Therefore, there are no discarded components in the upper harness.
Furthermore, the additional connection member can additionally connect an extended compartment environment functional component that is selectively retrofitted to the vehicle to be attached to any position of the upper harness. The extension passenger compartment functional parts can be retrofitted with the additional connecting member not only when the vehicle harness is manufactured, but also with the upper harness of the vehicle harness routed in the completed vehicle. That is, it becomes easy to configure a wire harness corresponding to a plurality of vehicle patterns in accordance with the addition of an extended compartment environment functional component (optional equipment) desired by the user (vehicle purchaser). Of course, even in that case, there are no components (circuit bodies, etc.) that are discarded.
Further, since the additional connecting member is branched and connected to the upper harness according to the number of the functional components for the extended passenger compartment environment that are attached to the attachment target vehicle, the discarded components are disposed in the entire harness structure for the vehicle. Does not occur.
In addition, in the conventional function addition method, due to the increase in the number of functional parts for the extended compartment environment, the product number of the entire wire harness increases with the number of combinations to which the functional parts for the extended compartment environment can be attached. On the other hand, in the vehicle compartment environment functional component connection system configured as described in (1) above, it is only necessary to ensure the product number of the additional connection member corresponding to the vehicle compartment environment functional component. Thereby, management of manufactured parts becomes easy, and reduction of wire harness manufacturing cost can be aimed at.
Furthermore, since the additional connecting member includes the expansion control unit, even if the functional component for the vehicle compartment environment retrofitted to the upper harness does not have the expansion control unit, it is easy to improve the function of the functional component for the vehicle cabin environment. It becomes.
In addition, when the expansion control unit incorporates a fuse function, for example, it is possible to directly connect to a higher-level harness or to simultaneously mount a plurality of functional components for the cabin environment. This makes it possible to add functions later (so-called “pong attachment”) and reduce the number of host harnesses and communication lines or signal lines.
Furthermore, since the expansion control unit incorporates a microcomputer, for example, it becomes easy to cope with control such as switch input, sensor input, and PWM (Pulse Width Modulation) output of functional components for the cabin environment. Since the control for these functional components for the passenger compartment environment is performed by a microcomputer, it is possible to easily cope with a change in specifications by software.

（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) The vehicle compartment environment functional component connection system configured as described in (1) above, wherein the upper harness and the additional connection member are connected to the conductor of the additional connection member and pressed against the conductor of the upper harness. A functional component connection system for a vehicle cabin environment, which is connected by a harness branch connection mechanism having a pressure contact portion to be connected and the expansion control portion.

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 compartment environment functional component connection system configured as described in (2) above, the additional connection member that connects the upper harness and the extended vehicle compartment environment functional component includes the expansion control unit at the connection portion with the upper harness. A harness branch connection mechanism is provided. This harness branching connection mechanism is attached to the upper harness so that the insulation covering portion covering at least the conductor of the communication line or the signal line in the upper harness is cut by the press contact portion, and the press contact portion is connected to the conductor. . Therefore, simply attaching the harness branch connection mechanism to the upper harness enables the connection between the upper harness and the extended compartment environment functional component to be completed easily.

（３）上記（１）または（２）の構成の車室環境用機能部品接続システムであって、前記拡張車室環境用機能部品は、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を分岐して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。 (3) The vehicle compartment environment functional component connection system configured as described in (1) or (2) above, wherein the extended vehicle compartment functional component is connected to the upper harness routed in a place to be retrofitted Is a functional component connection system for passenger compartment environment, characterized in that another power line is branched and connected.

上記（３）の構成の車室環境用機能部品接続システムによれば、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 compartment environment functional component connection system configured as described in (3) above, the upper harness routed in the immediate vicinity of the extended compartment environment functional component to be retrofitted is only a communication line or a signal line. If the electrical capacity of the power line in the upper harness is not sufficient, the power line of the additional connection member can be branched and connected to the power line of another harness routed in the vicinity of the functional component for the extended cabin environment Thus, it becomes possible to easily obtain the power source of the functional component for the extended passenger compartment environment. That is, since it is not necessary to route a new power supply line from the upper harness for the functional component for the extended passenger compartment environment, the power supply line system can be reduced.

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 functional component connection system for a passenger compartment environment according to the present invention, the space for mounting components can be saved, waste of discarding components can be eliminated, and component mounting properties 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。 Embodiments according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the functional component connection system for a passenger compartment environment according to an 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. It has as a new configuration. In this embodiment, the functional component connection system for the passenger compartment environment will be described with an example corresponding to three types of grades (LO, MID, Hi). The corresponding grade type 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 vehicle compartment environment functional component connection system according to the present embodiment, the standard control unit 19 controls the standard vehicle compartment environment functional component 17 that is attached in common to the attachment target vehicle. Hereinafter, the standard control unit 19 is referred to as an “air conditioner (A / C) ECU 19”. In the compartment environment functional component connection system, the A / C ECU 19 serves as a master, and the expansion control unit 15 used for connection of an optional extended compartment environment functional component described later serves as a slave. Therefore, one A / C ECU 19 is mounted in common for the LO grade, MID grade, and 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 the passenger compartment environment, the LO grade A / C ECU 19 includes, for example, a solar radiation sensor 21, an A / C pressure sensor 23, an outside air temperature sensor 25, an ECO switch 27, an inside air temperature sensor 29, and a PTC heater 31. , MGC 33, A / C compressor 35, DEF 37, and ion generator 39 are connected as functional components 17 for the standard vehicle compartment 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。 In addition to the standard compartment environment functional component 17 described above, the MID grade includes, for example, the flow sensor 41, the solar radiation sensor 43, the seat HTR 45, and the indoor blower blower 47 as the extended compartment environment functional component 49 in 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。 For the Hi grade, in addition to the LO grade standard compartment environmental functional part 17 and the MID grade extended compartment environmental functional part 49, for example, the temperature / humidity sensor 51, the exhaust sensor 53, the rear A / C switch 55, the DEICER 57, the ventilation Seat D seat 59, blower 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 sub ASSY 73, rear magnet valve 75, servo motor 77, Up to the No. 1 cooler thermistor 79 is connected to the A / C ECU 19 as the functional component 49 for the extended compartment 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。 Of the functional components for the passenger compartment environment, the ECO switch 27 supports the eco-driving of the driver and switches to the ECO mode, which is useful for improving fuel efficiency. The PTC heater 31 is a heater that uses a PTC element, and is used in a vehicle that cannot use the waste heat of a normal prime mover that uses warm 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 makes it easy to remove snow accumulated in the lower portion of the front shield because the lower portion of the front shield is heated.

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 harness 11. The upper harness 11 is an electric wire bundle based on three types of electric wires, that is, a power line 81, a communication line 83, and a GND 85 (ground line). Of course, the upper 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 needless to say, a form including other electric wires such as a signal line can 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 “retrofitted” to the upper harness 11 via the additional connecting member 13. That is, the extended compartment environment functional component 49 is connected to the A / C ECU 19 via the additional connecting 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 line 81, the communication line 83, and the GND 85 in the upper harness 11. The expansion control unit 15 is provided in this harness branch connection mechanism. Hereinafter, the harness branch connection mechanism having the expansion control unit 15 is referred to as an E connector 87. The additional connection member 13 is provided with an auxiliary machine connection mechanism 89 for connecting to an extended compartment environment functional component 49 that is selectively attached to the attachment target vehicle at the other end.

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 connecting member 13 includes an additional harness 91, an upper harness side connector 93 connected to the E connector 87 at the upper harness side end of the additional harness 91, and an additional harness 91 An accessory side connector 95 connected to the functional component 49 for the extended compartment environment is provided at the accessory side end of the harness 91. The additional connection member 13 is connected to an auxiliary machine connection mechanism 89 in which the auxiliary machine side connector 95 is configured together with the connector 97 provided in the functional component 49 for extended cabin environment, and the upper harness side connector 93 is connected to the E connector. It is connected to 87 board mounting connectors 99.
That is, the additional connecting member 13 of the present embodiment can connect the upper harness 11 and the extended compartment environment functional component 49 via the additional harness 91 having a simple structure having a desired length. Mounting according to the position of the functional component 49 for the passenger compartment environment is 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 auxiliary machine side connector 95 is connected to the extended vehicle cabin environment. The connector 97 is connected to the connector 97 of the functional component 49 for use.

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, the additional connecting member 103 shown in FIG. 2C is configured such that 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 harness side end of the additional harness 91 is connected. However, it is directly connected to the circuit of the extended compartment environment functional component 49 and is integrated with the extended compartment environment 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 includes a lower power line 105 and a 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 functional component 49 for extended vehicle cabin environment is various sensors, it is connected to the upper harness 11 by an additional harness including a sensor power supply line, a sensor signal line, and a sensor GND. When the extended compartment environment functional component 49 is a variety of switches, it is connected to the upper harness 11 by an additional harness that is a switch signal line corresponding to the number of connected switches.

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 FIGS. 3A to 3C, 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 press contact portion 109 is configured by erecting a plurality of press contact blades 111, for example, and is connected to a predetermined circuit on the circuit board 113. The circuit board 113 is accommodated in a case made of insulating resin constituted by an upper case 115 and a lower case 117. The upper case 115 and the lower case 117 are connected so as to be openable and closable 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。 The E connector 87 sandwiches the power line 81, the communication line 83, and the GND 85 in the upper harness 11 between the upper case 115 and the lower case 117, so that the pressure contact blade 111 cuts the insulation coating of each line, and the pressure contact portion 109 is formed on the conductor of each line. It is press-connected. The E connector 87 sandwiching the power line 81, the communication line 83, and the GND 85 in the upper harness 11 is fixed at an arbitrary position of the upper harness 11 by locking the upper case 115 and the lower case 117. That is, according to the vehicle compartment environment functional component connection system according to the present embodiment, the upper harness 11 and the extended vehicle compartment environment functional component 49 can be connected simply by attaching the E connector 87 to any position of the upper harness 11. Easy to complete. Note that, when the GND 85 of the functional component 49 for the extended passenger compartment environment is body-grounded, the branch connection by the additional connecting member 13 of the GND 85 in the upper harness 11 is not necessarily required. The case where branch connection is necessary is, for example, a case where the E connector 87 needs to be moved 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 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 harness 11 and the expansion control unit 15 is taken out to the outside by the board mounting 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。 In the passenger compartment environment functional component connection system of this embodiment, as described above, the A / C ECU 19 serves as a master, and the expansion control unit 15 serves as a slave.
Conventionally, one ECU centrally controls 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 expansion control unit 15 is provided in the additional connection member 13, and control is distributed 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 expansion control unit 15 controls the load according to the control signal received from the A / C ECU 19 by communication. Further, the expansion control unit 15 transmits a signal indicating the state of the switch or 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 includes 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 the load 129, the switch 131, and the sensor 133 by the additional connection member 13, for example. The presence / absence and 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 harness 11 is branched from, for example, a main line harness. The power supply power (for example, +12 V) supplied from the vehicle main power supply 135 is distributed to a plurality of systems inside the power distribution box 137 and supplied to the main wire harness 139 connected under the power 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 an electrical signal that turns on and off in accordance with, for example, a user operation. The sensor 133 outputs electrical signals representing various measurement values and states. The signal processing circuit 127 periodically processes electrical signals output from the switch 131 and the sensor 133, for example, 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。 A specific example of the load 129 is the functional component 49 for the extended passenger compartment environment. The expansion control unit 15 can drive the load 129 by energizing it. The extension control unit 15 includes a driver 123 for controlling energization of the load 129. The driver 123 incorporates a switching element such as a transistor, for example, and can perform on / off of the load 129 and duty control of the energization according to a 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 in accordance with an instruction from the A / C ECU 19 and 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. The wired communication interface 125 receives a control signal output from the A / C ECU 19 and provides the control signal to the driver 123. Also, various information output by the signal processing circuit 127 is transmitted to the A / C ECU 19 by data communication. In FIG. 4, an encoder that converts data into a coded signal and a decoder that reads the coded signal and converts it into the 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 functional component connection system for the passenger compartment environment of the present embodiment, serial communication can be performed as a data communication method, for example. In serial communication, one piece of information is divided into bits and sent to form one type of information. In serial communication, bit data is sent sequentially in time, so the communication speed is slower than that of parallel communication, but one communication line 83 can be provided. In serial communication, pulse signals “1” and “0” are arranged in order in time. One piece of information is identified by setting the end of the transmission data to a high level “1” and the beginning to a low level “0”. In this way, in the passenger compartment environment functional component connection system, a plurality of 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 functional component connection system for the passenger compartment environment of the present embodiment, the expansion control unit 15 can be considered as a node. As a connection form (topology) of a signal transmission circuit that connects nodes, the vehicle compartment environment functional component connection system uses a bus format. In the bus format, 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. In addition, a ring form or a star form may be used as a connection form of the signal transmission circuit of the functional component connection system for the passenger compartment environment.

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 functional component connection system for a passenger compartment environment according to the present invention will be described.
As shown in FIG. 5, the additional connection member 141 according to the modification is provided at the side of 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 for the extended compartment environment of the additional harness 149. The expansion vehicle compartment environment functional component side connector 151 to be connected and the E connector 87 connected to the upper harness side end of the additional signal line 147 are provided.
The extended harness environment functional component-side connector 151 of the additional harness 149 is connected to the equipment connector 157 of the expanded vehicle environment functional component 49 including the switch function portion 153 that switches in response to an on / off signal. . 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 supply line 143 is connected to the other harness 161 different from the upper harness 11. The power supply line 81 </ b> A is branched and connected via a pressure 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 another modification includes an additional harness 169 having an additional power line 143, an additional communication line 167, and an additional GND 145, and the function for an extended cabin environment of the additional harness 169. The expansion vehicle compartment environment functional component side connector 171 connected to the component side end and the harness branch connection mechanism 173 connected to the upper harness side end of the additional communication line 167 are provided. The expansion control unit 15 is provided in the expansion compartment environment functional component-side connector 171 connected to the expansion compartment environment functional component 49. 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 supply line 143 is another harness different from the upper harness 11. The power supply line 81 </ b> A in 161 is branched and connected to the power supply line 81 </ b> A via the pressure contact 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 FIGS. 5 and 6, the upper harness 11 that is routed in the immediate vicinity of the functional component 49 for the extended cabin environment to be retrofitted is only the signal line 159 or the communication line 83, If the electric capacity of the power supply line 81 in the harness 11 is not sufficient, there may be a case where power cannot be supplied from the upper harness 11 to the functional component 49 for the extended passenger compartment environment. In such a case, the additional power supply line 143 is branched and connected by the additional connection member 141 or the additional connection member 165 to the power supply line 81A of the other harness 161 that is routed in the vicinity of the functional component 49 for the extended passenger compartment environment. Thus, it becomes possible to easily obtain the power source of the functional component 49 for the extended passenger compartment environment.

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 effect | action of said functional component connection system for vehicle interior environments is demonstrated.
In the vehicle compartment environment functional component connection system according to the present embodiment, the upper harness 11 that is commonly attached to the attachment target vehicle is shared, and the expansion compartment environment functional component that is selectively attached to the attachment target vehicle. 49 is retrofitted through an additional connection member 13 having one end branched and connected to at least the communication line 83 or the signal line 159 of the upper harness 11. Therefore, the upper harness 11 does not have any discarded components.

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。 Further, the additional connecting member 13 can additionally connect an extended compartment environment functional component 49 selectively attached to the attachment target vehicle to any position of the upper harness 11. The extension passenger compartment functional component 49 can be retrofitted to the upper harness 11 of the vehicle harness routed to the completed vehicle as well as the vehicle harness. That is, it becomes easy to configure a wire harness corresponding to a plurality of vehicle patterns in accordance with the addition of the extended compartment environment functional component 49 (optional equipment) desired by the user (vehicle purchaser). Of course, even in that case, there are no components (circuit bodies, etc.) that are discarded.

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 connecting member 13 is branched and connected to the upper harness 11 according to the number of the functional components 49 for the extended passenger compartment environment that are attached to the attachment target vehicle, the additional connecting member 13 is discarded in the entire vehicle harness structure. No component parts are generated.
In addition, in the conventional function addition method, the number of functional parts 49 for the extended passenger compartment environment increases, and the part number of the entire wire harness increases with the number of combinations to which the functional parts 49 for the extended passenger compartment environment can be attached. On the other hand, in the vehicle compartment environment functional component connection system of the present embodiment, it is only necessary to secure the product number of only the additional connection member 13 corresponding to the extended vehicle compartment environment functional component 49. Thereby, management of manufactured parts becomes easy, and reduction of wire harness manufacturing cost can be aimed at.

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。 Further, since the additional connecting member 13 includes the expansion control unit 15, the extended vehicle compartment environment functional component 49 retrofitted to the upper harness 11 does not have the expansion control unit 15. The functional improvement of the functional component 49 is facilitated.
In addition, when said expansion control part 15 incorporates a fuse function, for example, it becomes possible to directly connect to the host harness 11 and to simultaneously mount a plurality of functional components 49 for the extended cabin environment. As a result, it is possible to add functions later (so-called “pong attachment”), and to reduce the number of systems of the upper harness 11 and the communication line 83 or the signal line 159.
Furthermore, since the expansion control unit 15 has a built-in microcomputer 119, it becomes easy to cope with control such as switch input, sensor input, and PWM (Pulse Width Modulation) output of the functional component 49 for the extended cabin environment. . Since the microcomputer 119 controls the function parts 49 for the extended passenger compartment environment, it is possible to easily cope with a specification change or the like 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 compartment environment functional component connection system of the present embodiment, the additional connection member 13 that connects the upper harness 11 and the extended vehicle compartment environment functional component 49 is connected to the upper harness 11 at the expansion control unit. E connector 87 having 15. The E connector 87 as the harness branching connection mechanism is attached to the upper harness 11 so that an insulating covering portion covering at least the conductor of the communication line 83 or the signal line 159 of the upper harness 11 is formed by the press contact portion 109. Cut and connect the pressure contact portion 109 to this conductor. Therefore, simply attaching the E connector 87 to the upper harness 11 simply completes the connection between the upper harness 11 and the extended compartment environment functional component 49.

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 compartment environment functional component connection system according to the present embodiment, the upper harness 11 that is routed in the immediate vicinity of the extended vehicle compartment environment functional component 49 to be retrofitted is only the communication line 83 or the signal line 159. If the electrical capacity of the power line 81 in the upper harness 11 is not sufficient, the additional connection member 141 or the additional connection member 141 is added to the power line 81A of the other harness 161 arranged in the vicinity of the extended compartment environment functional component 49. By branch-connecting the additional power supply line 143 of the connecting member 165, it is possible to easily obtain a power supply for the functional component 49 for the extended vehicle cabin environment. That is, since it is not necessary to route a new power supply line 81 from the upper harness 11 for the functional component for the extended passenger compartment environment, the power supply line 81 can be reduced.

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, it is possible to save the space for mounting components, eliminate waste of discarding components, and improve component mountability.
