    The invention relates to a cable harness for vehicles for transmitting electrical signals and / or electric working currents between vehicle control devices and peripheral devices mounted in the vehicle. vehicle. The invention also relates to a vehicle with such a bundle of cables. Furthermore, the invention relates to a method for manufacturing such a bundle of cables for vehicles.
    The on-board network of a vehicle, for example a road vehicle, an aeronautical vehicle or a rail vehicle, serves for the connection between individual control devices and peripheral devices distributed in a distributed manner in the vehicle. vehicle or so-called field devices. Such peripheral devices may for example be actuators and / or sensors as well as apparatus for the representation of information. The increasing number of driver assistance systems, engine control gear and complex infotainment systems in the automotive industry is accompanied by a drastic increase in the complexity of the onboard network, hence a significantly increased amount of cabling. The on-board network provides for the individual components, both the voltage supply on the one hand, and the data transmission link on the other hand. The installation and the realization of such an on-board network are generally carried out using bundles of cables, which constitute a bundling of electrical conductors for the transmission of electrical signals and electric working currents ( for the voltage supply). Such a bundle of cables can then be manufactured separately, by making the individual electrical conductors in advance and then bundling them together into a bundle, so that the entire bundle of cables can be integrated into the vehicle in a single operation. work encompassing the wiring and networking of the onboard network, which go with it. Otherwise it would be necessary to implement individually each electrical conductor in the vehicle, which would not be rational, if only for economic reasons.
    Due to the complexity of the onboard networks and the complexity of the resulting cable bundles, the cable bundle is most often still manufactured and installed by hand, in the automotive industry, but also in the automotive industry. the aeronautical and aerospace field. The steps of the manufacture of the wiring harness and the implementation can only be automated under extremely particular conditions, so that these manufacturing steps are a significant part of the costs of the onboard network.
    A conventional wiring harness still has the disadvantage that the wiring introduces a weight gain far from negligible for the vehicle, which can be estimated at 40 to 60 kg in modern vehicles. And particularly in the case of the consequent use of lightened materials, such as fiber-reinforced composite materials, the use of a conventional cable bundle is diametrically opposed to the principle of lightened construction.
    Accordingly, the purpose of the present invention is to indicate an improved cable bundle for on-board systems, on the one hand to reduce the weight and on the other hand to increase the degree of automation during the manufacture of the wire harness.
    This object is achieved by means of a cable harness for vehicles for transmitting electrical signals and / or electric working currents between vehicle control apparatus and peripheral devices mounted in the vehicle, the cable bundle comprising a plurality of conductors bundle for transmitting electrical signals and / or work currents, characterized in that at least a portion of the conductors of the cable bundle are formed by discrete conductive tracks, which form an integral part of a vehicle supporting structure which are formed by a composite material comprising an electrically conductive material forming the discrete conductive tracks, and which are provided in isolation from one another.
    The goal is further achieved by a vehicle having one or more vehicle control gear, one or more peripheral devices mounted in the vehicle, and a wiring harness for transmitting electrical signals and / or electric working currents. between the vehicle control gear and the peripheral devices mounted in the vehicle, the bundle comprising a plurality of bundled conductors for transmitting electrical signals and / or work currents, characterized in that at least a portion of the conductors of the cable bundle are formed by discrete conductive tracks, which form an integral part of a carrier structure of the vehicle, which are formed by a composite material comprising an electrically conductive material forming the discrete conductive tracks, and which are provided in such a manner as to isolated from each other .
    The goal is further achieved by a method for manufacturing a vehicle wiring harness for transmitting electrical signals and / or electric working currents between vehicle control gear and peripheral devices of the vehicle, comprising the following steps: a) supplying and preparing a composite material, which comprises a fiber-based material, an electrically conductive material and a matrix material, b) manufacturing a vehicle-carrying structure of the vehicle from the composite material supplied and prepared by curing the matrix material having been infused into the fiber-based material, the electrically conductive material of the composite material thus becoming integral with the vehicle supporting structure and forming discrete conductive tracks, and c) setting up elements connection, which come in contact with the electrical material It is a conductive element of the composite material, namely the manufactured vehicle supporting structure, for mutually connecting the control gear and the peripheral equipment of the vehicle, via the discrete conductive tracks.
    According to the invention, it is furthermore proposed to use a composite material, which comprises a fiber-based material, an electrically conductive material, in particular a metallic material, and a matrix material, for the manufacture of a carrier structure, which simultaneously forms with the electrically conductive material as integrated conductive tracks, a bundle of cables.
    According to the invention, there is provided a vehicle cable harness for transmitting electrical signals and / or working electric currents (supply voltages) between the vehicle control gear and mounted peripheral devices or devices. in the vehicle, the bundle of cables comprising a plurality of bundled conductors for the transmission of electrical signals and / or work currents.
    For the purposes of the present invention, vehicle control apparatus refers to data processing units used for controlling and regulating systems relating to the vehicle. A vehicle control apparatus refers herein to any signal processing apparatus which serves a defined purpose or purpose relating to the vehicle. Such vehicle control apparatus may for example be control gear for controlling assistance systems, engine control and control of navigation and infotainment systems.
    Peripheral devices mounted or implanted in the vehicle designate, in the context of the present invention, in particular the components provided for entry or entry or for the delivery of data and information. These may for example be sensors and / or actuators. As a rule, such peripheral devices or vehicle components are connected to the vehicle control gear, so that the peripheral devices as input or input devices supply data to the vehicle control gear, or as output devices supply corresponding information or control corresponding actuators by means of actuators. Peripheral devices can therefore be mechanical elements, such as valves, but also lighting systems, display screens or any type of sensor.
    According to the invention, it is now proposed that at least a portion of the conductors of the cable bundle are formed by discrete conductive tracks, which form an integral part of a vehicle supporting structure, which are formed by a composite material comprising an electrically conductive material forming the discrete conductive tracks, and which are provided in isolation from one another.
    Consequently, it is proposed that the individual conductors of a cable bundle be at least partly replaced by discrete conductive tracks, forming an integral part of a vehicle supporting structure, the integrated construction of the vehicle supporting structure being obtained by using a composite material, which comprises, apart from insulating materials, non-conductive, among others also an electrically conductive material which is an integral part of the composite material, and which ultimately, during the manufacture of the supporting structure of vehicle precisely with this composite material, forms the discrete conductive tracks, in an integrated manner.
    It is thus proposed that the vehicle supporting structure, for example structures supporting a bodywork such as longitudinal members, or wing structures in the aircraft, do not in themselves have the sole function of achieving and maintaining the structure of the vehicle. vehicle (the shape and geometry), but simultaneously form parts of the cable bundle, which makes obsolete the implementation of additional wiring, including the implementation of additional cable bundles. In other words, the vehicle supporting structure simultaneously constitutes also a part of the cable bundle, a separate wire bundle for wiring and the realization of the onboard network thus being replaced by the vehicle structure. The vehicle structure and the wiring harness are made in one and the same piece.
    This results firstly in the advantage of a weight gain, since now the vehicle carrying structure also forms the bundle of cables, thus allowing a double use. This makes it possible to gain weight as well as to increase the degree of automation during the manufacture of a bundle of cables, because the vehicle bearing structures are made of said composite material, thus allowing in a single step process, to manufacture both the vehicle supporting structure on the one hand, and parts of the cable bundle on the other hand. The manufacture of vehicle load bearing structures using composite materials, can then depending on the specific use case, be more highly automated than the manual construction and implementation of a bundle of cables. According to an advantageous embodiment, the discrete conductive tracks are formed by layers of electrically conductive material of a composite material comprising a plurality of layers of material, the layers of electrically conductive material being electrically insulated from each other by electrically-layered layers. insulating. According to this, the composite material is of a laminated construction and is optionally also constituted by other materials, but in particular by alternating layers of electrically conductive material and layers of electrically insulating material. The individual electrically conductive material layers here form one or more conductive tracks, one or more conductive tracks may be provided by layer of electrically conductive material. If a plurality of conductive tracks are provided per layer of electrically conductive material, these must be electrically insulated individually from each other within the layer of electrically conductive material. Between the layers of electrically conductive material there is provided an electrically insulating layer, which electrically isolates the individual electrically conductive material layers from each other, so that in the case of several layers of electrically conductive material assembled in a layered manner, it is thus possible to produce several superimposed conductive tracks, which then define, as a bundle of conductors, said bundle of cables.
    It has been found that these layers of electrically conductive material, as flat conductors, are well adapted, as conductive tracks, to replace the conductors of a bundle of cables, so that the electrical signals and / or the Working currents (voltage supply) may be transmitted using the layers of electrically conductive material of the composite material when a suitable vehicle supporting structure has been fabricated from the composite material. In the form of flat conductors, the layers of electrically conductive material here are able to compensate for the electrical resistance which is otherwise increased in the case of really small conductor sections, so that one can also continue working with the specified voltages vehicle control gear and vehicle components. According to a particularly advantageous embodiment for this purpose, the discrete conductive tracks are each formed by a layer of electrically conductive material of the composite material, so that each layer of electrically conductive material forms exactly a conductive track. With the aid of several superimposed layers of electrically conductive material (electrically insulated from one another), it is thus possible to produce a plurality of conductive tracks of the bundle of cables, the distribution of the conductive tracks being effected in the direction of the thickness of the part. .
    In one embodiment, the composite material comprises an electrically conductive fiber material and a matrix material, the electrically conductive fiber material forming the discrete conductive tracks. It is advantageous here to provide, apart from the electrically conductive fiber-based material, also an electrically nonconductive fiber-based material as an insulator, so here again the composite material is formed of a laminated construction of an electrically conductive fiber material on the one hand (e.g. CFRP or CFK carbon-fiber reinforced plastic material) and an electrically non-conductive fiber-based material (eg PRV or GFK glass-fiber-reinforced plastic material), a matrix material being infused and cured in the conductive and non-conductive fiber-based material to manufacture the vehicle supporting structure. The individual layers of the electrically conductive fiber-based material here form the conductive tracks of the cable bundle. The matrix material should preferably be electrically nonconductive.
    In another embodiment, the composite material comprises, as a hybrid material, a non-conductive fiber-based material, a matrix material and an electrically conductive metallic material, the electrically conductive metallic material forming the discrete conductive tracks. Here too, the electrically conductive metallic material may be laminated into the composite material, the non-conductive fiber material being provided as an electrical insulator between the electrically conductive metal layers. Such a hybrid composite material may for example be a glass fiber reinforced aluminum composite, which is also known by the name GLARE (Glass Laminate Aluminum Reinforced Epoxy).
    If a GLARE composite is used as a composite material, the composite material comprises several layers of material with alternating layers of aluminum and glass fiber layers, the aluminum layers forming the discrete conductive tracks. This hybrid composite material has the advantage that the impact tolerance, the resistance of the hole walls and the crash absorption can be improved by the integration of aluminum layers, which is particularly advantageous, both in the field than in aircraft construction. At the same time, these aluminum layers of a GLARE composite can be used as conductive tracks for a bundle of cables, so that the particular advantageous properties of these hybrid composite materials can be advantageously combined mutually.
    The goal is also achieved by means of a vehicle, the vehicle having one or more vehicle control gear, one or more body units or vehicle components mounted in the vehicle, and a wiring harness for transmitting signals. electric and / or electrical working currents between the vehicle control apparatus and the peripheral apparatus. According to the invention, the vehicle comprises a cable bundle previously described, at least a portion of the conductors of the cable bundle being formed by discrete conductive tracks, which form an integral part of a vehicle carrying structure of the vehicle, are formed by a composite material comprising an electrically conductive material forming the discrete conductive tracks, and which are provided in isolation from one another.
    Accordingly, the vehicle comprises according to the invention a vehicle supporting structure, made of a composite material comprising an electrically conductive material, for example in the form of several layers of electrically conductive material superimposed and between which is provided a layer of electrical insulation. The layers of electrically conductive material of the composite material are then electrically connected to the vehicle control gear on the one hand, and the peripheral devices on the other hand, thus now allowing a transmission of signals or work currents.
    For example, it is now possible to envisage a transmission of signals and / or work currents.
    It can thus be envisaged, for example, that the discrete conductive tracks of the vehicle structure, ie for example the layers of electrically conductive material of the composite material, are brought into contact with connection elements, so that the control equipment and the peripheral devices can be appropriately connected to the vehicle structure.
    Moreover, the goal is also achieved by the method according to the invention mentioned above. According to the invention there is provided a method for manufacturing a vehicle cable bundle, wherein a composite material comprising a fiber material, an electrically conductive material and a matrix material is provided and prepared. If a GLARE composite is used, the fiber-based material is a glass-fiber material, while the electrically-conductive material is an aluminum layer. But it can also be envisaged that fiber-based material and electrically conductive material form a single material.
    After the supply and the preparation of the composite material, the vehicle supporting structure is produced, for example by shaping the composite material as a semi-finished product, possibly infusing matrix material into the fiber-based material. then hardening the matrix material, so that an integral piece results in which the electrically conductive material is an integral part of the part and thus of the vehicle supporting structure.
    Connecting elements are then put in place, which come into contact with the electrically conductive material of the composite material, namely the manufactured vehicle supporting structure, in order to be able to connect together the vehicle control equipment and the peripheral devices of the vehicle. , via the discrete conductive tracks.
    As far as composite materials are concerned, fiber reinforced composite materials in combination with metal foils will normally be used here. The use of hybrid materials, such as a GLARE composite, is particularly advantageous, especially in the automotive field, for body parts. Instead of aluminum foils in the case of a conventional GLARE composite material, it is also conceivable to use thin sheets of steel, which makes it possible to increase the absorption capacity of the impacts. For fiber reinforced composites, for example, glass fiber fabrics are used as insulators. As regards conductive fiber-based composites, it is possible, for example, to use carbon fibers and aramid fibers. As regards the matrix system or matrix material, it is possible to envisage for example an ethylene-propylene-diene rubber (EPDM), which simultaneously has an electrical insulation effect. The invention will be explained with reference to the appended figure.
    This one shows:
    Figure 1 a schematic representation of a vehicle supporting structure comprising several layers.
    FIG. 1 shows a vehicle-carrying structure 10 in which a bundle of cables 11 is integrated. The vehicle-carrying structure 10 is here made of a composite material, which is of a laminated configuration where layers of electrically insulators 12 alternate with layers of electrically conductive material 13.
    In the embodiment of Figure 1, there is shown a cross section of the vehicle supporting structure 10, to show the principle of construction of the cable harness and the vehicle structure. The number of layers of insulating material 12 and layers of electrically conductive material 13 shown here is only exemplary, as are the shapes of the vehicle structure 10.
    If for the composite material, it is for example a GLARE composite, the layers of insulating material 12 are made of a plastic material reinforced with glass fibers, while the layers of electrically conductive material 13 are constituted by a layer of aluminum or an aluminum foil, the layers of insulating material 12 and the layers of electrically conductive material 13 being glued and compressed with each other.
    Each layer of electrically conductive material 13 in this case exactly forms a conductive track Li to 14, to be able to ensure the transmission of electrical signals and / or electric working currents (voltage supply).
    In the embodiment of FIG. 1, the conductive track Li is connected as a grounding layer (GND), whereas a voltage U1 to U3 can be applied respectively to the conductive tracks L2 to L4. The conductive tracks L1 and L2 are here connected to a lamp as an electrical receiver-consumer, while the conductive tracks L1 and L3 as well as L1 and L4 are also connected via an electrical receiver-consumer.
    If a voltage is now applied to the conductive track L2 (U1), this produces a flow of current through the conductive tracks L2, L1 as well as through the lamp as the electrical receiver-consumer, so that the lamp lights. It is the same with the other conductive tracks L3 and L_4.
    It is thus possible to integrate the elements of a cable bundle into a vehicle supporting structure, which makes it possible to avoid an additional bundle of cables and corresponding wiring in the vehicle. The exemplary embodiment of FIG. 1 is only indicated by way of example. It can be envisaged that the vehicle structure 10 has a large number of conductive tracks, for example twenty or thirty, permitting through them the supply of corresponding electrical signals and the supply voltage. The vehicle structure can thus be connected to vehicle control gear and bodywork apparatus, thereby building the onboard network via the vehicle structures.
