In the present description, the term "electrical system" means a system intended to provide a function of a vehicle. An electrical system SE1, SE2, SE3, SE4, SE5 can therefore be chosen, by way of non-limiting example, from the following list: a front-rear parking assistance device, an air conditioning, a power window, a display , an electric parking brake, etc. The electrical system SE1, SE2, SE3, SE4, SE5 may comprise a plurality of members 12a, 12b associated with a list of electrical connections in the form of tenants-outs, also called I / O, defining the connection topology of the organs 12a, 12b therebetween. In fact, the tenants-outs describe only the connections between the members 12a, 12b used for an electrical system SE1, SE2, SE3, SE4, SE5, in particular through connectors 15a, 15b and connecting elements 14a, 14b.

By "configuration" of a vehicle is meant for example a vehicle identifier CC1, CC2, CC3, CC4 for identifying a type of vehicle, or a version / range of a vehicle within a vehicle type. . A configuration CC1, CC2, CC3, CC4 may typically include a plurality of electrical systems SE1, SE2, SE3, SE4, SE5. Two different configurations CC1, CC2, CC3, CC4 vehicle may include electrical systems SE1, SE2, SE3, SE4, SE5 identical or similar but whose ins and outs are different, thus achieving different benefits.

In Figure 1 is illustrated a system 1 for generating electrical schematics of a motor vehicle and in particular electrical schematics relating to the electrical systems equipping the latter. This system 1 is able to implement a process for processing data relating to motor vehicles with a view to the subsequent graphical generation of electrical schematics of electrical systems and / or a method of graphical generation of electrical schematics which will be described later. .

This system 1 for generating electrical diagrams comprises a computer 2 such as a server, and a storage or data storage medium 7, which data relate to a database 6 as well as to a computer program . Note that this storage medium 7 may be in a variant a server. The computer 2 comprises in a non-limiting and non-exhaustive manner a processing unit 3 comprising hardware and / or software elements as well as a connection interface 4. The hardware and / or software elements of the processing unit 3 comprise more precisely at least one microprocessor cooperating with memory elements. This processing unit 3 is able to execute program code instructions for the implementation of the computer program.

The connection interface 4 of this computer 2 makes it possible to establish a communication link between the processing unit 3 and the storage medium 7 so as to exchange 8 data.

Thus, the processing unit 3 is then able to extract data from the database 6 and / or to inject it by creation or modification.

The database 6 comprises a first collection of data 10 that can correspond to the different electrical architectures relating to configurations CC1, CC2, CC3, CC4 of vehicles to be processed, in particular it can be data relating to elements of wiring C1. , C2, C3, C4, C5 industrial electrical manufactured for these different configurations CC1, CC2, CC3, CC4 of motor vehicles. More specifically, this data collection comprises for each vehicle configuration CC1, CC2, CC3, CC4, wiring element data defining the wiring elements C1, C2, C3, C4, C5, in which data is defined a case. use of each wiring element C1, C2, C3, C4, C5 linked for example to: a dashboard wiring assembly, a rear wiring assembly, front shield wiring assembly, etc ... These elements data wiring C1, C2, C3, C4, C5 comprise a set of information for determining the electrical architecture of each configuration of a vehicle. Indeed, this set of information makes it possible to define for each wiring element C1, C2, C3, C4, C5:

the members 12a, 12b of the electrical architecture to which this wiring element C1, C2, C3, C4, C5 is connected;

elements of connections and / or splices 13a, 13b of the electrical architecture, and

connecting elements 14a, 14b otherwise called wires constituting each wiring element C1, C2, C3, C4, C5. Note that the connecting elements 14a, 14b can be all separate or share common parts such as connecting elements 13a and / or splices 13b. The connecting elements 13a make it possible to fuse a part of at least two connecting elements 14a, 14b and the splices 13b make it possible to lengthen a connecting element 14a, 14b. It will be noted that the presence of a connecting element 13a is decided by the person skilled in electrical / electronic architecture and is not related to the number of members 12a, 12b to be connected.

The database 6 includes a second collection of data 1 1 relating to electrical systems SE1, SE2, SE3, SE4, SE5 of motor vehicles and configurations CC1, CC2, CC3, CC4 of motor vehicles. This second collection of data as described can correspond to the different configurations CC1, CC2, CC3, CC4 of the vehicles to be treated, it can in particular be the design data of the electrical systems SE1, SE2, SE3, SE4, SE5 of the vehicles. which comprise for each electrical function a representative file of a list of end-members and / or a list of members 12a, 12b. The first and second data collections preferably include the same data relating to the CC1, CC2, CC3, CC4 configurations of the vehicles. The system 1 also comprises a device 5 of drawings, in particular a paper or digital printing device in the form of an image or in vector form. This device 5 is able to exchange 9 data with the computer 2 and in particular with the processing unit 3 via the connection interface 4. This device 5 is able to generate the electrical schematics of the electrical systems of the vehicle.

As mentioned above and with reference to FIG. 2, such a system 1 is able to implement the method of processing data relating to motor vehicles with a view to the subsequent graphic generation of electrical schematics of electrical systems. of the vehicle.

To do this, the method comprises a reception step 16 by the processing unit 3 of the first data collection 10 included in the database 6.

The method then provides for a selection step 17 by the processing unit 3 in the first data collection 10, a list of wiring elements C1, C2, C3, C4, C5 and a list of configurations CC1 , CC2, CC3, CC4 of motor vehicles.

The method further comprises a step 18 for generating a first set of elements performed by the processing unit 3. Each element of this first set of elements comprises:

wiring elements C1, C2, C3, C4, C5 from the list of wiring elements C1, C2, C3, C4, C5, and a vehicle configuration CC1, CC2, CC3, CC4 associated with these wiring elements, resulting from the list of configurations CC1, CC2, CC3, CC4 of vehicles. These wiring elements C1, C2, C3, C4, C5 associated with this configuration CC1, CC2, CC3, CC4 of the vehicle comprise a set of information defining the electrical architecture of said vehicle. More specifically, the wiring elements C1, C2, C3, C4, C5 of each element of the first set of elements correspond to a data structure subsequently called "wiring data structure" comprising lists of elements relating to parameters / characteristics of the electrical architecture, associated with the configuration CC1, CC2, CC3, CC4 of the vehicle. This data structure comprises for example:

a list of connecting elements 14a, 14b in which each connecting element 14a, 14b is provided with two identified ends and is capable of ensuring electrical continuity between the members 12a, 12b of the vehicle;

a list of the members 12a, 12b of the vehicle which are interconnected by the connecting elements 14a, 14b;

a list of connection elements and / or splices 13a, 13b which are also connected to the connecting elements 14a, 14b in order to ensure electrical continuity between the members 12a, 12b, and

a list of the attributes of each link element defining the characteristics of each of them such as the signal, the color, the type of insulator, link code, etc.

Thus, with reference to FIG. 6A, during this step 18 the members 12a, 12b and the connecting elements 14a, 14b as well as the connecting and / or splicing elements 13a, 13b forming the electrical architecture of this configuration CC1 , CC2, CC3, CC4 of the vehicle are thus determined. Of moreover, this step 18 also makes it possible to identify the connections between the members 12a, 12b, the connecting elements 14a, 14b as well as the connecting and / or splicing elements 13a, 13b so as to define the relative electrical architecture this configuration CC1, CC2, CC3, CC4 of the vehicle.

As illustrated in FIG. 4, this first set of elements can be generated in the form of a matrix comprising for each line a wiring element and in particular the identifier C1, C2, C3, C4, C5 of the cabling element and for each column a vehicle configuration identified by the identifier CC1, CC2, CC3, CC4. Advantageously, in this case the configurations CC1, CC2, CC3, CC4 of vehicles are all different and the wiring elements C1, C2, C3, C4, C5 are all different in nature. Thus, this generation step 18 of this first set of elements can then provide for the filling of a matrix, each line of which is associated with a wiring element C1, C2, C3, C4, C5 resulting from the list of wiring elements C1. , C2, C3, C4, C5 and each column is associated with a configuration CC1, CC2, CC3, CC4 vehicle from the list of configurations CC1, CC2, CC3, CC4, each row of the matrix comprises, especially at the end filling the matrix, at least one association with a column of the matrix. It will be noted that the association of at least one row of the matrix with a column corresponds to an element of the first set of elements. Preferably, an element of the first set of elements corresponds to the association of several lines with the same column.

Such a matrix may be of the type illustrated in FIG. 4, which comprises, in the example, four configurations respectively identified by CC1, CC2, CC3, CC4 and five wiring elements C1, C2, C3, C4, C5 corresponding to cases each cabling element C1, C2, C3, C4, C5 as for example: dashboard wiring assembly, rear wiring assembly, front shield wiring assembly, etc. This matrix can be formed during the selection step 17 from the two associated lists and then filled during the generation step 18 of the first set of elements. At the end of its filling, that is to say when all the wiring elements C1, C2, C3, C4, C5 have been processed in order to verify their associations with the configurations CC1, CC2, CC3, CC4, the lines empty of the matrix that is to say, containing no association are deleted. This makes it possible to respond to a problem of optimizing the equipment of the processing unit 3, for example by limiting the memory size occupied by the matrix during the calculations carried out by the processing unit 3.

This association can be implemented by placing an indicator or an object in the box corresponding to the intersection between the corresponding line of the matrix and the corresponding column of the matrix. In other words, the matrix makes it possible to identify exactly all the wiring elements C1, C2, C3, C4, C5 with respect to each configuration CC1, CC2, CC3, CC4. In FIG. 4, the matrix is filled, the wiring C1 is present in the configurations CC1 and CC3, the wiring C2 in the configurations CC2 and CC4, etc. By way of example, the association of a line of the matrix and a column of the matrix corresponds to placing at this point in the matrix a pointer to the wiring data structure relating to a wiring element, for example a set of records in the database 6 which contains the data elements. elements related to said wiring element C1, C2, C3, C4, C5 associated with the configuration CC1, CC2, CC3, CC4. As we have already mentioned, this data structure comprises in particular a list of connecting elements 14a, 14b, a list of the organs 12a, 12b which are interconnected and a list of the connecting elements and / or of splices 13a, 13b. In other words, each "non-empty" box of the matrix is linked to an element of the first set of elements. The method subsequently provides a step of modifying the first set of elements from a second set of elements, each element of which comprises an electrical system SE1, SE2, SE3, SE4, SE5 associated with a configuration CC1. CC2, CC3, CC4 of the vehicle.

This second set of elements is defined during a determination step 20. More precisely, this step of determining this second set of elements comprises a step of reception by the processing unit 3 of the second collection of data. 1 1 included in the database 6.

This determination step 20 then provides for an implementation by the processing unit 3 of a selection step 22 in the second data collection 11, a list of electrical systems and a list of configurations CC1, CC2, CC3, CC4 of motor vehicles.

The determining step 20 then comprises a step 23 of generating the second set of elements from these lists of electrical systems SE1, SE2, SE3, SE4, SE5 and configurations CC1, CC2, CC3, CC4 of motor vehicles.

In this second set of elements each element comprises:

an electrical system SE1, SE2, SE3, SE4, SE5, resulting from the list of electrical systems SE1, SE2, SE3, SE4, SE5, and

a vehicle configuration CC1, CC2, CC3, CC4 associated with this electrical system SE1, SE2, SE3, SE4, SE5, resulting from the list of configurations CC1, CC2, CC3, CC4.

More specifically, the electrical system SE1, SE2, SE3, SE4, SE5, of each element of the second set of elements corresponds to a data structure subsequently called "data structure of electrical function "comprising lists of elements related to the electrical functions relating to parameters / characteristics of the electrical system SE1, SE2, SE3, SE4, SE5, associated with the configuration CC1, CC2, CC3, CC4. This data structure comprises for example:

a list of the members 12a, 12b included in this electrical system SE1, SE2, SE3, SE4, SE5 associated with the configuration CC1, CC2, CC3, CC4, and

a list of connectors 15a, 15b or ins and outs of the members 12a, 12b

Each member 12a, 12b comprises a connection module comprising a plurality of cells, hereinafter called connectors 15a, 15b or "PIN" or input-output. Thus it is understood that the list of connectors 15a, 15b is a list of cells of this connection module or a list of "PIN".

It will be noted that two electrical systems SE1, SE2, SE3, SE4, SE5 of the same nature may comprise the same list of members 12a, 12b but lists of different tenants-outs or a list of different members 12a, 12b. Electrical systems are considered to be identical when they comprise the same members 12a, 12b and the same lists of tenants-outs. The organs 1 2a, 12b and / or tenants-resulting can then be parameters or a content of an electrical system SE1, SE2, SE3, SE4, SE5. For example, a low-end air conditioning and a high-end air conditioning are two electrical systems SE1, SE2, SE3, SE4, SE5 of the same nature and may include the same members 12a, 12b, however the connections between these organs 12a, 12b may be different so that some high-end air conditioning features are not enabled in low-end air conditioning. It should be noted that an association between an electrical system SE1, SE2, SE3, SE4, SE5, and a vehicle configuration CC1, CC2, CC3, CC4 can be realized when the electrical system SE1, SE2, SE3, SE4, SE5, actually part of the electrical architecture of the configuration CC1, CC2, CC3, CC4 of the vehicle.

It should be noted that the selection and generation steps 23 of this step of determining the second set of elements are performed in a manner substantially similar to the selection and generation steps described in a data management / data processing method defined in the second set of elements. documents FR1351903 and FR1351904.

With reference to FIG. 5, this second set of elements can be generated in the form of a matrix comprising for each line an electrical system SE1, SE2, SE3, SE4, SE5 and for each column a configuration CC1, CC2, CC3 , CC4 of vehicle. Advantageously, in this case the configurations CC1, CC2, CC3, CC4 of vehicles are all different and the electrical systems SE1, SE2, SE3, SE4, SE5 are all different in nature. In other words, the generation step of the second set of elements may comprise the filling of a matrix, each line of which is associated with an electrical system SE1, SE2, SE3, SE4, SE5 (from the list of electrical systems) and each column is associated with a configuration CC1, CC2, CC3, CC4 vehicle (from the list of configurations), each row of the matrix includes, especially at the end of the filling of the matrix, at least one association with a column of the matrix, said association corresponding to an element of the second set of elements. Such a matrix may be of the type illustrated in FIG. 4, which comprises, in the example, four configurations identified respectively by CC1, CC2, CC3, CC4 and five electrical systems SE1, SE2, SE3, SE4, SE5 being able respectively to correspond respectively to a help device parking, an airbag, an air conditioning, a door opening system and a lighting system, etc. This matrix can be formed during the selection step 22 from the two associated lists and then filled during of the generation step 23 of the second set of elements. This makes it possible to respond to a problem of optimizing the equipment of the processing unit 3, for example by limiting the memory size occupied by the matrix during the calculations carried out by this processing unit 3. It will be noted that this association can be set implement by placing an indicator or an object in the box corresponding to the intersection between the corresponding line of the matrix and the corresponding column of the matrix. In other words, the matrix makes it possible to identify exactly the schemas to be generated. In FIG. 5, the matrix is filled, the electrical system SE1 is present in the configurations CC1 and CC3, the electrical system SE2 in the configuration CC2, the electrical system SE3 in the configuration CC3, the electrical system SE4 is present in the configurations CC1, CC2 and CC4 and the electrical system SE5 is present in the configurations CC1, CC3 and CC4. In other words, if we take the example of the electrical system SE1, the latter is to be generated for the configurations CC1 and CC3. For example, the association of a row of the matrix and a column of the matrix corresponds to placing at this point in the array a pointer to the structure of electrical function data, for example a set of records in the base which contains the elements related to the electrical functions including parameters of the electrical system SE1, SE2, SE3, SE4, SE5, associated with the configuration CC1, CC2, CC3, CC4. In particular this data structure comprises contents of the electrical system SE1, SE2, SE3, SE4, SE5, associated with the configuration CC1, CC2, CC3, CC4, for example a list of connectors 15a, 15b or ins and outs, and / or the organs 12a, 12b of the system, etc. In other words, each box "no empty "of the matrix (example CC1 and CC3 for the electrical system SE1) is linked to all the data of the electrical function of the configuration (s) concerned. In this method, the step of modifying the first set of elements from the second set of elements comprises a step of selecting the element of the second set of elements defining the electrical system SE1, SE2, SE3. SE4, SE5, for the configuration CC1, CC2, CC3, CC4 of the vehicle associated with the wiring elements C1, C2, C3, C4, C5 of the element of the first set of elements. In other words, the electrical system SE1, SE2, SE3, SE4, SE5, for which a diagram must be generated is then selected, this electrical system SE1, SE2, SE3, SE4, SE5, is defined for a configuration CC1, CC2, CC3 , Vehicle CC4 corresponding to the vehicle configuration CC1, CC2, CC3, CC4 included in the element of the first set of elements. In the embodiment described the electrical system SE1, SE2, SE3, SE4, SE5 selected, and which is subsequently defined in FIGS. 6A to 6E, relates to a front-rear parking assistance device of a vehicle.

This modification step 19 of the first set of elements then comprises an identification step 25 in the element of the first set of elements, of the electrical system SE1, SE2, SE3, SE4, SE5 relating to the configuration CC1, CC2, CC3, CC4 of the vehicle that is defined in the element of the second set. To do this, this identification step 25 comprises a selection step 26 of the organs 12b included in the list of organs 12a, 12b of the element of the first set of elements from the organs 12b included in the list of organs 12b relative to the electrical system SE1, SE2, SE3, SE4, SE5, defined in the element of the second set of elements. This selection step 26 of the organs 12b in the element of the first set of element is illustrated in Figure 6B. Indeed, in this FIG. 6B, only the members 12b included in the electrical system SE1, SE2, SE3, SE4, SE5 relating to the element of the second set of elements are selected.

This identification step then provides a step of determining electrical continuity between the selected members 12b in the element of the first set of elements. This electrical continuity between the selected members 12b is ensured in particular by the connecting elements 14b which directly connect the members 12b to each other or indirectly from the connecting elements 13a or splices 13b. More precisely, this step of determining the electrical continuity between the selected members 12b provides:

an identification step 28 of the connectors 15b of the selected members 12b of the element of the first set of elements from the list of connectors 15a, 15b defined in the element of the second set of elements. This identification step 28 of the connectors 15b in the element of the first element set is illustrated in FIG. 6C. Indeed, in this FIG. 6C, only the connectors 15b included in the electrical system SE1,

SE2, SE3, SE4, SE5 relating to the element of the second set of elements are identified;

- A selection step 29 of the connecting elements 14b which are connected to these connectors 15b identified in the element of the first set of elements especially from the list of connecting elements 14b.

This step of selecting link members 14b in the element of the first element set is illustrated in FIG. 6D. Indeed, in this FIG. 6D, only the connection elements 14b included in the system SE1, SE2, SE3, SE4, SE5 relative to the element of the second set of elements are selected.

In the case where the determined connecting element 14b connects two members 12b selected between them through a connecting member 13a or a splice 13b, this connecting element 14b is then formed of two parts. These two parts form an electrical continuity between the two members 12b selected if they share two connection terminals arranged vis-a-vis the connecting member 13a, or through the same splice 13b. Note that the connecting elements 14b can be all separate or share common parts. For example, as we have just seen, the connecting elements 14b may comprise connecting elements 13a for fusing a part of at least two connecting elements 14b, as well as splices 13b making it possible to lengthen a connecting element 14b.

In FIGS. 2 and 6E, the modification step 19 then provides for a deletion step 30 in the list of the elements 12a, 12b and the list of the connecting elements 14a, 14b of the element of the first set of elements, elements 12a and connecting elements 14a which have not been selected during the modification step 19. In fact, in FIG. 6E only the elements of the members 12b, the connecting elements 14b and the connecting elements and / or splices constituting the electrical system SE1, SE2, SE3, SE4, SE5 are present in the element thus modified of the first set of modified elements.

This modified element of the first set of modified elements is capable of defining the electrical diagram of the electrical system SE1, SE2, SE3, SE4, SE5, to be generated. The method then comprises a processing step 31 of each modified element of the first set of elements. This processing step 31 aims to prepare the route of each of the modified elements of the first set of elements, in particular to facilitate readability and optimize the time of drawing. Such a treatment step is known in the state of the art and described for example in the document FR1351904.

Under these conditions, this processing step 31 makes it possible to obtain for each modified element of the first set of elements, a digital object comprising all the characteristics of an electrical diagram to be generated. Once the digital object has been constituted, the processing step 31 may comprise a step 32 for storing the digital object in the database 6. The advantage of such a digital object is that it is easy to manipulate in terms of memory and to modify if one wishes to improve it. It is understood from what has been said above that the implementation of the treatment method and in particular of the treatment step subsequently makes it possible to obtain optimized electrical diagrams very quickly.

As mentioned above and with reference to FIG. 3, the system 1 is able to implement the method of graphical generation of electrical diagrams comprising a step of implementing the treatment method as described, and a graphical generating step (i.e., plotting on one page), for each modified element of the first set of elements, of a circuit diagram of the associated electrical system SE1, SE2, SE3, SE4, SE5 ( in particular from the digital object referred to above) by data transmission 9, in particular by the processing unit 3, relating to said modified element to a drawing device 5, in particular a digital paper printing device in the form of picture or in vector form. Advantageously, the invention makes it possible to improve the accuracy and to bring a considerable saving of time in the generation of electrical diagrams since the graphically generated diagrams will be directly the right ones. The invention thus makes it possible to divide the workload implemented in the processes of the state of the art for the generation of such schemes by three. Moreover, the invention makes it possible to improve the quality of the electrical diagrams by a total and perfect correspondence with the electrical systems (in particular the members and the connecting elements) implemented in the configuration of the vehicles concerned. Study phases have shown a significant time saving of up to 60%.

The invention also relates to a data storage medium 7 capable of exchanging data with the processing unit 3 via the connection interface 4 so that this processing unit 3 can read the relative content at the base. 6. Thus, on such a data storage medium 7 readable by the processing unit 3 is recorded the computer program comprising computer program code means for implementing the steps of one or more several of the methods described above.

An aspect of the invention also relates to a computer program comprising program code instructions for performing the steps of one or more of the methods described above when said program is executed by the processing unit 3 .

The present invention is not limited to the embodiment which has been explicitly described, but it includes the various variants and generalizations thereof within the scope of the claims below.
