[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.
[0011] The wiring system of the present disclosure is as follows.
[0012] (1) A wiring system comprising a multi-purpose wiring member including a multi-purpose circuit and a multi-purpose connector to which the multi-purpose circuit is connected, and exclusively comprising: a first-purpose wiring member including a first-purpose circuit and a first-purpose connector to which the first-purpose circuit is connected, electrically connecting the first-purpose circuit to a first electrical component; and a second-purpose wiring member including a second-purpose circuit and a second-purpose connector to which the second-purpose circuit is connected, electrically connecting the second-purpose circuit to a second electrical component of a different type from the first electrical component; wherein when the first-purpose connector is connected to the multi-purpose connector, the multi-purpose circuit is connected to the first-purpose circuit, and when the second-purpose connector is connected to the multi-purpose connector, the multi-purpose circuit is connected to the second-purpose circuit.
[0013] According to this wiring system, when the first-purpose connector is connected to the multi-purpose connector, the multi-purpose circuit is used to connect to the first electrical component. When the second-purpose connector is connected to the multi-purpose connector, the multi-purpose circuit is used to connect to the second electrical component. Therefore, while the multi-purpose circuit can be used to wire to the first electrical component or the second electrical component, the multi-purpose wiring member can be used for both vehicle specifications equipped with the first electrical component and vehicle specifications equipped with the second electrical component. This makes it possible to easily accommodate multiple vehicle specifications while reducing the number of circuits.
[0014] (2) In the wiring system of (1), the second-purpose wiring member may be connected to the second electric component that is mounted exclusively with respect to the first electric component in a vehicle. In this case, the first electric component and the second electric component are mounted exclusively with respect to the vehicle. Therefore, it is not necessary to simultaneously incorporate a circuit for the first electric component and a circuit for the second electric component in the multi-purpose wiring member. In this way, the circuit for the first electric component and the circuit for the second electric component, which do not need to be provided separately, can be used as a multi-purpose circuit.
[0015] (3) In the wiring system of (1) or (2), when a plurality of exclusive equipment systems are set in which a first equipment specification including the first electrical component and a second equipment specification including the second electrical component are exclusively adopted, the multi-purpose circuit may include a circuit that is exclusively connected to the first electrical component and the second electrical component, corresponding to each of at least two of the plurality of exclusive equipment systems.
[0016] In this way, when multiple exclusive equipment systems are provided, the multi-purpose circuit can be shared by both the first equipment specification and the second equipment specification for at least two of the systems, allowing the multi-purpose wiring member to accommodate a variety of combinations of multiple exclusive equipment systems.
[0017] (4) In any one of the wiring systems (1) to (3), the multi-purpose wiring member may include a plurality of circuits including at least one of the multi-purpose circuits, and the number of the at least one multi-purpose circuit may be 10% or more of the total number of the plurality of circuits in the multi-purpose wiring member. This effectively reduces the number of circuits in the multi-purpose wiring member. Note that the total number of the plurality of circuits in the multi-purpose wiring member refers to the total number of circuits included in the multi-purpose wiring member, regardless of the purpose of the circuits. For example, if the multi-purpose wiring member includes a common circuit used as the same type of electrical transmission path regardless of whether a first-purpose wiring member or a second-purpose wiring member is selected, the total number of the plurality of circuits in the multi-purpose wiring member refers to the total number of circuits including the common circuit.
[0018] (5) In the wiring system of any one of (1) to (4), the multi-purpose circuit may include a circuit that transmits different types of electricity when the first-purpose connector is connected to the multi-purpose connector and when the second-purpose connector is connected to the multi-purpose connector. This allows the multi-purpose circuit to be used as a circuit that transmits different types of electricity.
[0019] (6) In the wiring system of any one of (1) to (5), the multi-purpose circuit may include a circuit that transmits different electricity for power, ground, or signals when the first-purpose connector is connected to the multi-purpose connector and when the second-purpose connector is connected to the multi-purpose connector. This allows the multi-purpose circuit to be used as a circuit that transmits different electricity for power, ground, or signals.
[0020] The multi-purpose wiring member of the present disclosure is as follows.
[0021] (7) A multi-purpose wiring member having a multi-purpose circuit connected to different types of electrical components.
[0022] According to this multi-purpose wiring member, the multi-purpose circuit can be shared for wiring different types of electrical components. This eliminates the need to prepare separate circuits for different types of electrical components. Furthermore, the multi-purpose wiring member can be used for vehicle specifications equipped with different types of electrical components. This allows for easy compatibility with multiple vehicle specifications with a smaller number of circuits.
[0023] [Details of the embodiments of the present disclosure] Specific examples of the wiring system and multi-purpose wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.
[0024] [Embodiment 1] The wiring system and wiring member according to the first embodiment will be described below.
[0025] <Wiring systems in vehicles> <Examples of systems installed in vehicles> For ease of explanation, an example of a system installed in a vehicle will be described. A diagram showing a wiring system 30 in a vehicle 10 is shown. The vehicle 10 is equipped with a common equipment system 12. The common equipment system 12 is a system that is installed in vehicles of a specific platform or a specific model, regardless of differences in grade and optional parts. For example, if a common instrument panel system is installed in vehicles of a specific platform or a specific model, the instrument panel system is an example of the common equipment system 12. The common equipment system 12 includes at least one electrical component 12a, 12b for realizing the function of the common equipment system 12. For example, if the common equipment system 12 is an instrument panel system, the common equipment system 12 includes, as the electrical components 12a, 12b, a display device that displays various information to the driver, switches that accept various instructions from the driver, an ECU (Electronic Control Unit), etc. The ECU, for example, controls the display of the display device, accepts instructions via the switches, and accepts various signals from various sensors and other ECUs. Although two electric components 12a and 12b are shown in FIG. 1 as an example, the number and positions thereof are not particularly limited.
[0026] An exclusive equipment system 14 is set in the vehicle 10. The exclusive equipment system 14 is a system that allows the first equipment specification 16 and the second equipment specification 18 to be exclusively adopted on the vehicle 10. Here, "exclusive" means that if any one of multiple situations is realized, the other situations are not realized. Therefore, "the first equipment specification 16 and the second equipment specification 18 can be exclusively adopted" means that if the first equipment specification 16 is adopted, the second equipment specification 18 cannot be adopted, and if the second equipment specification 18 is adopted, the first equipment specification 16 cannot be adopted. In this case, the exclusive equipment system 14 does not exclude the possibility of adopting a third equipment specification, a fourth equipment specification, etc. as another exclusive option in addition to the first equipment specification 16 and the second equipment specification 18.
[0027] An example of an exclusive equipment system is when the first equipment specification 16 is an automatic transmission (AT) specification and the second equipment specification 18 is a manual transmission (MT) specification. For example, if the first equipment specification 16 is an automatic transmission (AT), the exclusive equipment system includes electrical components 16a, 16b, 16c, and 16d, such as a sensor for detecting the position of a shift lever, a switch for receiving a command for an automatic transmission operation mode, an automatic transmission mechanism including various solenoids and sensors that changes the rotation speed of a drive source, and an automatic transmission ECU. The automatic transmission ECU controls the gear ratio of the automatic transmission mechanism in accordance with, for example, vehicle speed, engine rotation speed, accelerator operation, and the like. For example, if the second equipment specification 18 is a manual transmission (MT), the exclusive equipment system includes electrical components 18a, 18b, and 18c, such as a sensor for detecting the position of a shift lever, a sensor for detecting the position of a clutch pedal, and an engine ECU. In this embodiment, the description will be given assuming that the first equipment specification 16 is an automatic transmission (AT) specification and the second equipment specification 18 is a manual transmission (MT). The AT specification and the MT specification are exclusively installed on the vehicle 10 as specifications in which the rotation of the driving source for traveling is transmitted to the wheels after being changed in speed.
[0028] Although FIG. 1 illustrates two electric components 12a and 12b, four electric components 16a, 16b, 16c, and 16d, and two electric components 18a, 18b, and 18c, the number and positions of these components are arbitrary.
[0029] Another example of an exclusive equipment system is when the first equipment specification is a mechanical key specification and the second equipment specification is a smart key specification. The mechanical key specification is a system in which the driver inserts a key held by the driver into a keyhole located around the door or steering wheel to lock and unlock the vehicle doors, switch the steering wheel to an unlocked state, and switch the power source to an operable state. The smart key specification is a system in which the driver performs operations such as locking and unlocking the vehicle doors, switching the steering wheel to an unlocked state, and switching the power source to an operable state by wireless communication between a wireless communication device mounted in the vehicle and a wireless key terminal held by the driver. Note that the smart key specification may include configuration related to the mechanical key specification. The mechanical key specification does not incorporate configuration related to the smart key specification. The mechanical key specification and the smart key specification are exclusively installed in the vehicle as security specifications for locking and unlocking various parts of the vehicle.
[0030] Another example of an exclusive equipment system is a vehicle driving power system in which a first equipment specification is a specification for an internal combustion engine and a second equipment specification is a specification for a hybrid system consisting of an internal combustion engine and an electric motor. In this case, the first equipment specification or the second equipment specification may be a specification for an electric motor. In addition to the first equipment specification and the second equipment specification, a specification for an electric motor may be set as a third equipment specification. Each of these specifications is installed exclusively on the vehicle as a system related to the vehicle's driving power.
[0031] Another example of an exclusive equipment system is a vehicle audio / visual system in which a first equipment specification is a simple specification and a second equipment specification is a luxurious specification. For example, the first equipment specification may include only a radio receiver and speakers, while the second equipment specification may include a multimedia player, a display device, multi-channel speakers, a camera for capturing images outside the vehicle, etc.
[0032] In the above examples of the common equipment system and the exclusive equipment system, some of the electrical components constituting the common equipment system and some of the electrical components constituting the exclusive equipment system may be shared by both. Also, some of the electrical components constituting the first equipment specification set as the exclusive equipment system and some of the electrical components constituting the second equipment specification may be common.
[0033] The first equipment specification and the second equipment specification may be specifications that are exclusively selected during vehicle manufacture, or may be specifications that are exclusively selected after vehicle manufacture. After either the first equipment specification or the second equipment specification is selected during vehicle manufacture, the specification may be changed to the other of the first equipment specification and the second equipment specification. For example, the vehicle's audio and video systems may have specifications that are exclusively selected after vehicle manufacture, or may be specifications that are changed from either the first equipment specification or the second equipment specification to the other after vehicle manufacture.
[0034] <About the wiring system> The wiring system 30 will be described with reference to Fig. 1. Note that circuits 42, 45, 52, 55, 62, 65, 72, etc., shown by a single line in Fig. 1, may include multiple circuits.
[0035] The wiring system 30 includes a multi-purpose wiring member 40, and further includes a first-purpose wiring member 50 and a second-purpose wiring member 60 exclusively. As described above, "exclusively" here means that when the first-purpose wiring member 50 is included, the second-purpose wiring member 60 is not included, and when the second-purpose wiring member 60 is included, the first-purpose wiring member 50 is not included; this does not deny the possibility of the existence of a third-purpose wiring member, a fourth-purpose wiring member, etc. in the system 30 as a whole.
[0036] The multi-purpose wiring member 40 includes a multi-purpose circuit 42 and a multi-purpose connector 46 .
[0037] The multi-purpose circuit 42 is a component that is configured with a linear conductive member and transmits electricity. The multi-purpose circuit 42 may be used for transmitting electrical signals or power. The multi-purpose circuit 42 may be, for example, a core of an electric wire having a core wire and a surrounding sheath. The electric wire may be an untwisted electric wire, a twisted electric wire, or a cable with a surrounding shielding layer. The multi-purpose circuit 42 does not have to be a core of an electric wire. For example, the multi-purpose circuit 42 may be a conductor formed along a predetermined path on a flat insulating substrate. For example, the multi-purpose circuit may be a circuit pattern of an FPC (Flexible Printed Circuit), in which a circuit pattern made of metal foil or the like is formed between a pair of resin films. In this embodiment, the multi-purpose circuit 42 is assumed to be a core of an electric wire. The description of the multi-purpose circuit 42 in this paragraph can be similarly applied to circuits 42, 43, 44, 45, 52, 55, 62, 65, 72, etc., described below.
[0038] The multi-purpose circuit 42 is a circuit that can be used for both the first-purpose wiring member 50 and the second-purpose wiring member 60. In other words, the multi-purpose circuit 42 is a circuit that can be used as an electrical transmission path in both the first equipment specification 16 and the second equipment specification 18. In other words, "multi-purpose" means that it has multiple uses. The multi-purpose circuit 42 can also be said to be a circuit that is connected to different types of electrical components 16a, 16b, 16c, and 16d or electrical components 18a, 18b, and 18c depending on the selected specification.
[0039] The multi-purpose connector 46 is a connector to which the multi-purpose circuit 42 is connected. The multi-purpose connector 46 is exclusively connected to a first purpose connector 56 or a second purpose connector 66, which will be described later.
[0040] The multi-purpose wiring member 40 may include a common circuit 45. The common circuit 45 is a circuit that is used as a transmission path for the same type of electricity regardless of whether the first-purpose wiring member 50 or the second-purpose wiring member 60 is selected. The common circuit 45 is, for example, a circuit that is electrically connected to the electrical components 12a and 12b that make up the common equipment system 12. There may be more common circuits 45, for example, more than the number of circuits related to the exclusive equipment system 14. It is not essential that the multi-purpose wiring member 40 include the common circuit 45.
[0041] The multi-purpose wiring member 40 may include a common connector 48. The common connector 48 is a connector used as a connection interface to other wiring members or electrical components, regardless of whether the first-purpose wiring member 50 or the second-purpose wiring member 60 is selected. For example, it is assumed that the common circuit 45 is connected to the common connector 48. It is not essential that the multi-purpose wiring member 40 include the common connector 48.
[0042] The first purpose wiring member 50 includes a first purpose circuit 52 and a first purpose connector 56. Three first purpose wiring members 50 are shown in FIG.
[0043] The first application circuit 52 is connected to the first application connector 56. When the first application connector 56 is connected to the multi-purpose connector 46, the multi-purpose circuit 42 is electrically connected to the first application circuit 52. The first application circuit 52 is electrically connected to the electrical components 16a, 16b, 16c, and 16d in the first equipment specification 16. The first application circuit 52 may be connected to the electrical components 16a, 16b, 16c, and 16d via connector C. The other end of the first application circuit 52 may be led directly to the electrical components 16a, 16b, 16c, and 16d and connected to the electrical elements of the electrical components 16a, 16b, 16c, and 16d without using a connector. The electrical components 16a, 16b, 16c, and 16d are examples of first electrical components.
[0044] The second-purpose wiring member 60 includes a second-purpose circuit 62 and a second-purpose connector 66. FIG. 1 illustrates three second-purpose wiring members 60 corresponding to the three first-purpose wiring members 50. The number of first-purpose wiring members 50 does not necessarily have to be the same as the number of second-purpose wiring members 60. In this case, it is conceivable that there is no connection destination for the multi-purpose connector 46 depending on the specifications. The first-purpose wiring members 50 and the second-purpose wiring members 60 are assembled to the vehicle 10 exclusively according to the selected specifications. In other words, the second-purpose wiring member 60 is connected to a second electrical component (e.g., electrical components 18a, 18b, 18c) that is mounted exclusively to a first electrical component (e.g., electrical components 16a, 16b, 16c, 16d) in the vehicle 10.
[0045] The second purpose circuit 62 is connected to the second purpose connector 66. When the second purpose connector 66 is connected to the multi-purpose connector 46, the multi-purpose circuit 42 is electrically connected to the second purpose circuit 62. The second purpose circuit 62 is electrically connected to the electrical components 18a, 18b, 18c in the second equipment specification 18. The second purpose circuit 62 may be connected to the electrical components 18a, 18b, 18c, 18d via connector C. The other end of the second purpose circuit 62 may be directly led to the electrical components 18a, 18b, 18c and connected to the electrical elements of the electrical components 18a, 18b, 18c without a connector. The electrical components 18a, 18b, 18c, 18d are examples of second electrical components that are different in type from the first electrical component. The first electrical component and the second electrical component being different in type means, for example, that they can be understood as being of different types as a result of different applied specifications. It is also possible that some of the first electrical components constituting the first equipment specification and some of the second electrical components constituting the second equipment specification are the same components.
[0046] The first purpose connector 56 and the second purpose connector 66 are connected to the same multi-purpose connector 46. For this reason, it is assumed that the second purpose connector 66 is the same connector as the first purpose connector 56. However, since the numbers of first purpose circuits 52 and second purpose circuits 62 are different, it is assumed that the numbers of connector terminals of the first purpose connector 56 and the second purpose connector 66 are different, or at least one of the first purpose connector 56 and the second purpose connector 66 is provided with a dummy connector terminal that is not connected to an electric wire.
[0047] In the first-purpose wiring member 50 or the second-purpose wiring member 60, if there are multiple electrical components to be connected to the multi-purpose connector 46, the multiple first-purpose circuits 52 or the multiple second-purpose circuits 62 may branch off along the way. In FIG. 1 , the multiple first-purpose circuits 52 branch off along the way in accordance with the electrical components 16b, 16c of the first equipment specification 16.
[0048] The first-purpose wiring member 50 and the second-purpose wiring member 60 may each have a terminal-side common circuit 55, 65 for the electrical components 12a, 12b in the common equipment system 12. FIG. 1 shows an example in which the first-purpose wiring member 50 has the terminal-side common circuit 55 and the second-purpose wiring member 60 has the terminal-side common circuit 65 corresponding to the electrical component 12a. The terminal-side common circuit 55 is connected to the first-purpose connector 56, and the terminal-side common circuit 65 is connected to the second-purpose connector 66. When the first-purpose wiring member 50 is selected, the common circuit 45 in the multi-purpose wiring member 40 is connected to the electrical component 12a via the terminal-side common circuit 55. When the second-purpose wiring member 60 is selected, the common circuit 45 in the multi-purpose wiring member 40 is connected to the electrical component 12a via the terminal-side common circuit 65. In other words, the terminal-side common circuits 55, 65 are circuits connected to electrical components of the same type regardless of their specifications.
[0049] 1, a terminal-side common wiring member 70 is connected to the common connector 48. The terminal-side common wiring member 70 includes a circuit 72 and a connector 76. One end of the circuit 72 is connected to the connector 76, and the other end of the circuit 72 is connected to an electrical component 12b in the common equipment system via a connector C or without a connector. When the connector 76 is connected to the common connector 48, the common circuit 45 in the multi-purpose wiring member 40 is connected to the electrical component 12b via the circuit 72. In other words, the terminal-side common wiring member 70 does not include the first purpose circuit 52 and the second purpose circuit 62, which depend on specifications, and is a wiring member that is connected to the same type of electrical components regardless of specifications.
[0050] <Example of wiring system> Based on the wiring system 30 described in Fig. 1, a specific example of the wiring system 30 will be described with reference to Fig. 2. While circuits, connectors, etc. are distinguished in Fig. 2, the number of circuits, paths, and connectors is merely an example and may be changed depending on the system and specifications to which it is applied. For ease of explanation, each circuit in Fig. 2 is distinguished by a solid line, a thick line, a dotted line, a two-dot chain line, etc.
[0051] The multi-purpose wiring member 40 includes at least one (for example, five) multi-purpose circuit 42. Hereinafter, the multiple multi-purpose circuits 42 will be classified as multi-purpose circuits 42a, 42b, 42c, 42d, and 42e as necessary.
[0052] The multi-purpose wiring member 40 includes at least one (e.g., six) main line side first purpose circuit 43. Hereinafter, as necessary, the multiple main line side first purpose circuits 43 are classified as main line side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f.
[0053] The multi-purpose wiring member 40 includes at least one (e.g., five) main line side second use circuits 44. Hereinafter, as necessary, the multiple main line side second use circuits 44 are distinguished as main line side second use circuits 44a, 44b, 44c, 44d, and 44e.
[0054] The multi-purpose connectors 46 in the multi-purpose wiring member 40 are classified into multi-purpose connectors 46A, 46B, and 46C according to the connection destination. The multi-purpose connectors 46A, 46B, and 46C and the common connector 48 each include, for example, a plurality of connector terminals 46a (some of which are shown in FIG. 2) and a connector housing 46b. Ends of the multi-purpose circuit 42, the main line-side first-purpose circuit 43, and the main line-side second-purpose circuit 44 are connected to any of the connector terminals 46a in the multi-purpose connectors 46A, 46B, and 46C and the common connector 48.
[0055] Here, multi-purpose circuits 42a, 42b, 42c, and 42d have one end connected to a connector terminal in multi-purpose connector 46B, and the other end connected to a connector terminal in multi-purpose connector 46C. Multi-purpose circuit 42e has one end connected to a connector terminal in multi-purpose connector 46A, and the other end connected to a connector terminal in multi-purpose connector 46C.
[0056] One end of each of the main line side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f is connected to a connector terminal of the multi-purpose connector 46A, and the other end is connected to a connector terminal of the multi-purpose connector 46B.
[0057] One end of each of the main line side second purpose circuits 44a, 44b, and 44c is connected to a connector terminal of the multi-purpose connector 46A, and the other end is connected to a connector terminal of the multi-purpose connector 46C. One end of each of the main line side second purpose circuits 44d and 44e is connected to a connector terminal of the multi-purpose connector 46B, and the other end is connected to a connector terminal of the multi-purpose connector 46C.
[0058] One end of common circuit 45 is connected to a connector terminal in multi-purpose connector 46A, and the other end is connected to a connector terminal in common connector 48. When the above-mentioned multiple circuits pass through the same path, the multiple circuits may be kept bundled together by a bundling member 90 such as adhesive tape or a cable tie.
[0059] In this example of the multi-purpose wiring member 40, the total number of circuits is 17, and the total number of circuits for the exclusive equipment system 14 excluding the common circuit 45 is 16. In addition, the number of multi-purpose circuits 42 is 5. Therefore, the number of multi-purpose circuits 42 out of the total number of circuits in the multi-purpose wiring member 40, 17, is approximately 29.41%. The number of multi-purpose circuits 42 out of the total number of circuits for the exclusive equipment system 14, 16, is 31.25%.
[0060] The multiple first-purpose wiring members 50 are divided into first-purpose wiring members 50A, 50B, and 50C. The first-purpose wiring member 50A is connected to the multi-purpose connector 46A, the first-purpose wiring member 50B is connected to the multi-purpose connector 46B, and the first-purpose wiring member 50C is connected to the multi-purpose connector 46C. Focusing on the first equipment specification 16, the first-purpose wiring member 50A is connected to the electric component 16a, the first-purpose wiring member 50B is connected to the electric components 16b and 16c, and the first-purpose wiring member 50C is connected to the electric component 16d.
[0061] The first purpose wiring member 50A has at least one (e.g., seven) first purpose circuit 52 and a terminal-side common circuit 55. The multiple first purpose circuits 52 are classified into first purpose circuits 52a, 52b, 52c, 52d, 52e, 52f, and 52g.
[0062] When the first purpose connector 56 is connected to the multi-purpose connector 46A, the first purpose circuits 52a, 52b, 52c, 52d, 52e, and 52f are electrically connected to the main-side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f, and the first purpose circuit 52g is connected to the multi-purpose circuit 42e. Therefore, the main-side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f and the multi-purpose circuit 42e are electrically connected to the electric component 16a via the first purpose circuits 52a, 52b, 52c, 52d, 52e, 52f, and 52g.
[0063] The common circuit 45 is electrically connected to the electrical component 12a via a terminal-side common circuit 55. The main line-side second purpose circuits 44a, 44b, 44c are open circuits on the multi-purpose connector 46A side.
[0064] The first purpose wiring member 50B has at least one (e.g., ten) first purpose circuits 52. The multiple first purpose circuits 52 branch off as they leave the first purpose connector 56 and are connected to the electrical components 16b and 16c. When the first purpose connector 56 is connected to the multi-purpose connector 46B, the first purpose circuit 52 is connected to the main-side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f and the multi-purpose circuits 42a, 42b, 42c, and 42d. Therefore, the main-side first purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f and the multi-purpose circuits 42a, 42b, 42c, and 42d are electrically connected to the electrical component 16b or 16c via the first purpose circuits 52 of the first purpose wiring member 50B. In this case, the main line side second application circuits 44d and 44e are in an open state in the multi-purpose connector 46B.
[0065] The first-purpose wiring member 50C also has at least one (e.g., five) first-purpose circuit 52. When the first-purpose connector 56 is connected to the multi-purpose connector 46C, the first-purpose circuit 52 is connected to the multi-purpose circuits 42a, 42b, 42c, 42d, and 42e. Therefore, the multi-purpose circuits 42a, 42b, 42c, 42d, and 42e are electrically connected to the electrical component 16d via the first-purpose circuit 52 of the first-purpose wiring member 50C. In this case, the main-side second-purpose circuits 44a, 44b, 44c, 44d, and 44e are in an open state in the multi-purpose connector 46C.
[0066] As in the above, the plurality of second-purpose wiring members 60 are classified into second-purpose wiring members 60A, 60B, and 60C.
[0067] The second purpose wiring member 60A has at least one (for example, three) second purpose circuit 62 and a terminal-side common circuit 65. The second purpose circuits 62 are classified into second purpose circuits 62a, 62b, 62c, and 62d.
[0068] When the second purpose connector 66 is connected to the multi-purpose connector 46A, the second purpose circuits 62a, 62b, 62c are electrically connected to the main side second purpose circuits 44a, 44b, 44c, and the second purpose circuit 62d is connected to the multi-purpose circuit 42e. As a result, the main side second purpose circuits 44a, 44b, 44c and the multi-purpose circuit 42e are electrically connected to the electrical component 18a via the second purpose circuits 62a, 62b, 62c, 62d.
[0069] As in the case where the first-purpose wiring member 50A is selected, the common circuit 45 is electrically connected to the electrical component 12a via the terminal-side common circuit 65. Unlike the case where the first-purpose wiring member 50A is selected, the main-line-side first-purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f are in an open state on the multi-purpose connector 46A side.
[0070] The second-purpose wiring member 60B has at least one (e.g., six) second-purpose circuit 62. When the second-purpose connector 66 is connected to the multi-purpose connector 46B, the second-purpose circuit 62 is connected to the main-side second-purpose circuits 44d, 44e and the multi-purpose circuits 42a, 42b, 42c, and 42d. Therefore, the main-side second-purpose circuits 44d, 44e and the multi-purpose circuits 42a, 42b, 42c, and 42d are electrically connected to the electrical component 18b via the second-purpose circuit 62 of the second-purpose wiring member 60B. In this case, the main-side first-purpose circuits 43a, 43b, 43c, 43d, 43e, and 43f are in an open state in the multi-purpose connector 46B.
[0071] The second-purpose wiring member 60C also has at least one (e.g., ten) second-purpose circuit 62. When the second-purpose connector 66 is connected to the multi-purpose connector 46C, the second-purpose circuit 62 is connected to the multi-purpose circuits 42a, 42b, 42c, 42d, and 42e and the main-side second-purpose circuits 44a, 44b, 44c, 44d, and 44e. Therefore, the multi-purpose circuits 42a, 42b, 42c, 42d, and 42e and the main-side second-purpose circuits 44a, 44b, 44c, 44d, and 44e are electrically connected to the electric component 18c via the second-purpose circuit 62 of the second-purpose wiring member 60C.
[0072] When the wiring system 30 is applied to the first equipment specification 16, the first-purpose wiring members 50A, 50B, and 50C are selected. In this case, the multi-purpose circuit 42 and the main line-side first-purpose circuit 43 in the multi-purpose wiring member 40 are used, and the main line-side second-purpose circuit 44 is left open at each connector and unused.
[0073] When the wiring system 30 is applied to the second equipment specification 18, the second-purpose wiring members 60A, 60B, and 60C are selected. In this case, the multi-purpose circuit 42 and the main line-side second-purpose circuit 44 in the multi-purpose wiring member 40 are used, and the main line-side first-purpose circuit 43 is left open at each connector and unused.
[0074] In either case, the multi-purpose circuit 42 is used. That is, the multi-purpose circuit is utilized as a circuit for multiple specifications. Since the multi-purpose circuit is used as a multi-purpose circuit in common among the multiple specifications, the number of circuits as wiring members for the multiple specifications can be reduced.
[0075] <Example for comparison> For comparison, let's consider a case where no multi-purpose circuit is used. Figure 3 shows a wiring system 130 exclusively for the first equipment specification 16 as a first example. In this case, the main wiring member 140 is assumed to have a configuration in which the main-side second-purpose circuit 44 is omitted from the multi-purpose wiring member 40 of the wiring system 30. It is assumed that the connectors of the main wiring member 140 and the first-purpose wiring member 150 corresponding to the first-purpose wiring member 50 use connectors C1 of a size having connector terminals corresponding to the number of reduced circuits. The main wiring member 140 has a total of 12 circuits, and the total number of circuits related to the exclusive equipment system is 11.
[0076] 4 shows a wiring system 230 exclusively for the second equipment specification 18 as a second example. In this case, it is assumed that the main wiring member 240 has a configuration in which the main-side first-purpose circuit 43 is omitted from the multi-purpose wiring member 40 of the above-mentioned wiring system 30. It is assumed that the connector of the main wiring member 240 and the second-purpose wiring member 260 corresponding to the second-purpose wiring member 60 use a connector C2 of a size having connector terminals in a number corresponding to the reduced number of circuits. The main wiring member 240 has a total of 11 circuits, and the total number of circuits related to the exclusive equipment system is 10.
[0077] If separate main wiring components 140, 240 are prepared for the first equipment specification 16 and the second equipment specification 18, the number of wiring component control items and inventory management will increase. Simply combining the main wiring components 140, 240 to accommodate both the first equipment specification 16 and the second equipment specification 18 would result in an excessive increase in the number of circuits. For example, if the main wiring components 140, 240 were simply combined, the total number of circuits would be 22, calculated by subtracting the number of 45 common circuits from the simple sum. If only the circuits related to the exclusive equipment system were considered, the total number of circuits after the combination would be 21.
[0078] In contrast, in the present wiring system 30, the multi-purpose circuit 42 is used in both the first equipment specification 16 and the second equipment specification 18. Differences in circuit length, routing, connection configuration, etc., resulting from differences in the types of electrical components 16a, 16b, 16c, and 16d of the first equipment specification 16 and the electrical components 16a, 16b, and 16c of the second equipment specification 18 are eliminated by the first-purpose wiring member 50 or the second-purpose wiring member 60. The use of the multi-purpose circuit 42 allows for a reduction in the number of circuits. In the example shown in FIG. 2, the multi-purpose wiring member 40 includes five multi-purpose circuits 42, which reduces the number of circuits by five compared to simply combining the main wiring members 140 and 240.
[0079] The greater the ratio of the number of multi-purpose circuits 42 to the total number of circuits in the multi-purpose wiring member 40, the greater the effect of reducing the number of circuits. For example, the number of multi-purpose circuits to the total number of circuits in the multi-purpose wiring member 40 may be 10% or more. The number of multi-purpose circuits to the total number of circuits in the multi-purpose wiring member 40 is preferably 15% or more, more preferably 20% or more, even more preferably 25% or more, and even more preferably 30% or more.
[0080] Similarly, the ratio of the number of multi-use circuits 42 to the total number of circuits for the exclusive equipment system 14 in the multi-use wiring member 40 may be 10% or more, preferably 15% or more, more preferably 20% or more, even more preferably 25% or more, and even more preferably 30% or more.
[0081] <Example of multi-purpose circuit connection destination> Fig. 5 is an explanatory diagram showing examples of connections of the multi-purpose circuit 42. Fig. 5 shows an example in which the multi-purpose circuits 42a, 42b, 42c, and 42d are connected to the electric component 16c via the first-purpose wiring member 50 and an example in which they are connected to the electric component 18b via the second-purpose wiring member 60.
[0082] As shown in FIG. 5, the multi-purpose circuit 42 includes circuits 42c and 42d that transmit different types of electricity when the first purpose connector 56 is connected to the multi-purpose connector 46B and when the second purpose connector 66 is connected to the multi-purpose connector 46B.
[0083] A circuit that transmits different types of electricity is, for example, a circuit in which the first equipment specification 16 and the second equipment specification 18 have different applied voltages, different expected maximum current values, or different signal formats.
[0084] The multi-purpose connector 46 may include circuits 42c, 42d that transmit different electricity for power, ground, or signals when the first purpose connector 56 is connected to the multi-purpose connector 46B and when the second purpose connector 66 is connected to the multi-purpose connector 46B.
[0085] 5, when the first-purpose connector 56 of the first-purpose wiring member 50 is connected to the multi-purpose connector 46B, the multi-purpose circuit 42c is connected to the actuator 81 and serves as a circuit for supplying power to the actuator 81. On the other hand, when the second-purpose connector 66 of the second-purpose wiring member 60 is connected to the multi-purpose connector 46B, the multi-purpose circuit 42c is connected to the sensor 83 and serves as a circuit for transmitting a detection signal.
[0086] Furthermore, when the first-purpose connector 56 of the first-purpose wiring member 50 is connected to the multi-purpose connector 46B, the multi-purpose circuit 42d is connected to the communication circuit 82 and becomes a circuit for transmitting communication signals. On the other hand, when the second-purpose connector 66 of the second-purpose wiring member 60 is connected to the multi-purpose connector 46B, the multi-purpose circuit 42d is connected to the earth circuit 84 and becomes a circuit for transmitting electricity for earthing purposes.
[0087] The cross-sectional size of the multi-purpose circuit 42 is not particularly limited. For example, if the multi-purpose circuit 42 is the core of an electric wire, the cross-sectional area of the core may be classified as 0.13 sq, 0.35 sq, 0.5 sq, or 2 sq. sq is a standard for the cross-sectional area of the core defined by the JIS standard and stands for square millimeters. The multi-purpose circuit 42 can be used for various electrical transmission purposes within the range of allowable current depending on the cross-sectional area, material, etc. of the circuit.
[0088] <Effects, etc.> With the wiring system 30 and multi-purpose wiring member 40 configured as described above, when the first-purpose connector 56 is connected to the multi-purpose connector 46, the multi-purpose circuit 42 is used to connect to a first electrical component (e.g., electrical components 16a, 16b, 16c, and 16d). When the second-purpose connector 66 is connected to the multi-purpose connector 46, the multi-purpose circuit 42 is used to connect to a second electrical component (e.g., electrical components 18a, 18b, and 18c). Therefore, the multi-purpose circuit 42 can be used to wire to the first or second electrical component, reducing the number of control part numbers, while the multi-purpose wiring member 40 can be used for both the first equipment specification 16 that includes the first electrical component and the second equipment specification 18 that includes the second electrical component. This allows the number of circuits to be reduced while easily accommodating the equipment specifications 16 and 18 of multiple vehicles.
[0089] Furthermore, the first electrical component (e.g., electrical components 16a, 16b, 16c, and 16d) and the second electrical component (e.g., electrical components 18a, 18b, and 18c) are mounted exclusively on the vehicle. Therefore, it is not necessary to simultaneously incorporate a circuit for the first electrical component and a circuit for the second electrical component in the multi-purpose wiring member 40. In this way, the circuit for the first electrical component and the circuit for the second electrical component, which do not need to be provided separately, can be used as the multi-purpose circuit 42.
[0090] Furthermore, if the number of at least one multi-purpose circuit 42 relative to the total number of circuits in the multi-purpose wiring member 40 is 10% or more, the number of circuits in the multi-purpose wiring member 40 can be effectively reduced.
[0091] Furthermore, by using the multi-purpose circuit 42 as a circuit for transmitting different types of electricity, the number of circuits in the multi-purpose wiring member 40 can be effectively reduced regardless of the type of electricity being transmitted.
[0092] Furthermore, for example, by using the multi-purpose circuit as a circuit that transmits different electricity for power, earth, or signals, the circuit can be used for multiple purposes without being distinguished as power, earth, or signals, and the number of circuits in the multi-purpose wiring member 40 can be effectively reduced.
[0093] <Modification of the First Embodiment> FIG. 6 shows a wiring system 330 according to a modification of the first embodiment. In this modification, the first equipment specification is a mechanical key specification, and the second equipment specification is a smart key specification. The first electrical components 316a, 316b, 316c, and 316d for the first equipment specification include a door lock unit that detects the state of a cylinder lock installed in the door, an interior lock unit that detects the state of a cylinder lock installed around the steering wheel, various actuators that perform steering wheel locking and door locking, and an ECU that controls various locking states in the vehicle. The second electrical components 318a, 318b, 318c, and 318d for the second equipment specification include a communication circuit that wirelessly communicates with a wireless key terminal carried by the driver, various actuators that perform steering wheel locking and door locking, and an ECU that controls authentication based on output from the communication circuit and various locking states in the vehicle.
[0094] The wiring system 330 includes a multi-purpose wiring member 340 corresponding to the multi-purpose wiring member 40, and also exclusively includes a first purpose wiring member 350 corresponding to the first purpose wiring member 50 and a second purpose wiring member 360 corresponding to the second purpose wiring member 60.
[0095] In this modification, four first-purpose wiring members 350 and four second-purpose wiring members 360 are exclusively selected according to the specifications. Therefore, a multi-purpose circuit 342 corresponding to the multi-purpose circuit 42 in the multi-purpose wiring member 340, a main-side first-purpose circuit 343 corresponding to the main-side first-purpose circuit 43, and a main-side second-purpose circuit 344 corresponding to the main-side second-purpose circuit 44 are branched and connected to four multi-purpose connectors 346 corresponding to the multi-purpose connectors 46.
[0096] The first purpose wiring member 350 includes a first purpose circuit 352 corresponding to the first purpose circuit 52 and a first purpose connector 356 corresponding to the first purpose connector 56. The second purpose wiring member 360 includes a second purpose circuit 362 corresponding to the second purpose circuit 62 and a second purpose connector 366 corresponding to the second purpose connector 66.
[0097] As described in the first embodiment, when the first equipment specification is selected, the first purpose connector 356 of the first purpose wiring member 350 is connected to the multi-purpose connector 346. As a result, the multi-purpose circuit 342 and the main line side first purpose circuit 343 in the multi-purpose wiring member 340 are electrically connected to the first electrical components 316a, 316b, 316c, and 316d via the first purpose circuit 352. At this time, the main line side second purpose circuit 344 is maintained in an open state at the multi-purpose connector 346.
[0098] Furthermore, when the second equipment specification is selected, the second purpose connector 366 of the second purpose wiring member 360 is connected to the multi-purpose connector 346. As a result, the multi-purpose circuit 342 and the main line side second purpose circuit 344 in the multi-purpose wiring member 340 are electrically connected to the second electric components 318a, 318b, 318c, and 318d via the second purpose circuit 362. At this time, the main line side first purpose circuit 343 is maintained in an open state at the multi-purpose connector 346.
[0099] This modification also provides the same effects as those of the first embodiment.
[0100] [Embodiment 2] A wiring system according to a second embodiment will be described. In the description of this embodiment, the same components as those described in the first embodiment and its modifications will be denoted by the same reference numerals, and the description thereof will be omitted. Fig. 7 is an explanatory diagram showing a wiring system 430 according to the second embodiment.
[0101] The wiring system 430 is a system that assumes a case where multiple exclusive equipment systems are set, in which a first equipment specification and a second equipment specification are exclusively adopted. In this embodiment, as described in the first embodiment, an exclusive equipment system for a drivetrain system in which the first equipment specification 16 is an automatic transmission specification and the second equipment specification 18 is a manual transmission specification is set, and an exclusive equipment system for a key system in which the first equipment specification is a mechanical key specification and the second equipment specification is a smart key specification is set, as described in the modified example, is set.
[0102] In this embodiment, the wiring system 430 includes a multi-purpose wiring member 440. The multi-purpose wiring member 440 is configured by integrating the multi-purpose wiring member 40 of the first embodiment and the multi-purpose wiring member 340 of the modified example. The multi-purpose wiring member 440 includes, as multi-purpose circuits 42, 342, a multi-purpose circuit 42 corresponding to an exclusive equipment system related to the drive transmission system, and a multi-purpose circuit 342 corresponding to an exclusive equipment system related to the key system.
[0103] The multi-purpose wiring member 40 and the multi-purpose wiring member 340 may be integrated by being bound together with a binding member 490 such as adhesive tape or a cable tie. The circuits of the multi-purpose wiring member 40 and the circuits of the multi-purpose wiring member 340 may be mixed and bundled together.
[0104] The wiring system 430 exclusively includes a first-purpose wiring member 50 and a second-purpose wiring member 60 (partially shown in FIG. 7) that correspond to an exclusive equipment system related to the drive transmission system. The wiring system 430 also exclusively includes a first-purpose wiring member 350 and a second-purpose wiring member 360 (partially shown in FIG. 7) that correspond to an exclusive equipment system related to the key system.
[0105] Then, the first purpose wiring member 50 and the second purpose wiring member 60 are exclusively selected according to the specification selection of the exclusive equipment system for the drive transmission system, and as described in the above embodiment 1, the multi-purpose circuit 42 is exclusively connected to the electrical components 16a, 16b, 16c, 16d or the electrical components 18a, 18b, 18c according to the selection.
[0106] Furthermore, by exclusively selecting the first purpose wiring member 350 and the second purpose wiring member 360 in accordance with the specification selection of the exclusive equipment system related to the key system, the multi-purpose circuit 342 is exclusively connected to the electrical components 316a, 316b, 316c, 316d or the electrical components 318a, 318b, 318c, 318d in accordance with the selection, as described in the above modified example.
[0107] This wiring system 430 can achieve the same effects as those of the first embodiment. In addition, when multiple exclusive equipment systems are provided, the multi-purpose circuits 42, 342 can be shared by both the first equipment specification and the second equipment specification for at least two of the systems. This allows the multi-purpose wiring member 440 to accommodate a variety of combinations of multiple exclusive equipment systems, contributing to a reduction in the number of product numbers for the multi-purpose wiring member 440.
[0108] In addition, when a vehicle is equipped with multiple exclusive equipment systems, it is not necessary to provide a multi-purpose circuit for all of the exclusive equipment systems. In this case, it is assumed that a common part number will be used for some of the exclusive equipment systems based on the specifications of the multi-purpose circuit, and that multi-purpose wiring members will be prepared for each specification for the other exclusive equipment systems.
[0109] [Note] In manufacturing the above wiring system, a manufacturing method including the following processes can be adopted.
[0110] A multi-purpose wiring member including a multi-purpose circuit and a multi-purpose connector to which the multi-purpose circuit is connected, a first-purpose wiring member including a first-purpose circuit and the first-purpose connector to which the first-purpose circuit is connected, electrically connecting the first-purpose circuit to a first electrical component, and a second-purpose wiring member including a second-purpose circuit and a second-purpose connector to which the second-purpose circuit is connected, electrically connecting the second-purpose circuit to a second electrical component of a different type from the first electrical component, is prepared; when electrically connecting the multi-purpose circuit to the first electrical component, the first-purpose wiring member is selected, and the first-purpose connector is connected to the multi-purpose connector to electrically connect the multi-purpose circuit to the first electrical component via the first-purpose circuit; and when electrically connecting the multi-purpose circuit to the second electrical component, the second-purpose wiring member is selected, and the second-purpose connector is connected to the multi-purpose connector to electrically connect the multi-purpose circuit to the second electrical component via the second-purpose circuit.
