[0048] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0050] The present disclosure provides a method and device for checking common lines of automobile wiring harnesses, a medium and an apparatus.

[0051] Figure 1 A flowchart of a method for checking common lines of automobile wiring harnesses is provided. The method can use node triangles representing segmented wiring harnesses to find repeated node triangles on common wiring harnesses between any two automobile wiring harnesses, and then determine the target common line length more accurately according to the line lengths of the segmented wiring harnesses corresponding to the node triangles. The method can be executed by a device for checking common lines of automobile wiring harnesses, which can be implemented in software and / or hardware; for example, an electronic device or a server. The electronic device can include a vehicle-mounted processor, a mobile phone, a tablet computer, a desktop computer, a notebook computer, and other devices with communication functions. The server can be a cloud server or a server cluster, and other devices with storage and computing functions. It should be noted that the following embodiments are exemplarily explained with the electronic device as the execution subject.

[0052] As shown in Figure 1 the method for checking common lines of automobile wiring harnesses includes the following steps:

[0053] S102, acquiring node triangles representing segmented wiring harnesses in the automobile wiring harnesses in a wiring harness schematic diagram.

[0054] The wiring harness schematic diagram can include logical information of connection wiring harnesses between electrical devices and between electrical devices and ground on the automobile. The automobile wiring harnesses in the wiring harness schematic diagram can be divided into multiple modules according to regions, such as a left front door wiring harness assembly, a right front door wiring harness assembly, a roof wiring harness assembly, a cabin wiring harness assembly, a rear motor wiring harness assembly, and an instrument panel wiring harness assembly.

[0055] In the online harness schematic diagram, each automobile harness can be divided into multiple segmented harnesses according to segmented features such as welding points, branch positions, harness positions, etc. A node triangle is marked on each segmented harness, for example, a node triangle is marked at the center point of the segmented harness; and detailed information of the segmented harness such as harness length, signal type, harness type, etc. is associated with the node triangle marked on the segmented harness. Thus, each segmented harness can be identified by a node triangle, and the node triangle is associated with multiple information of the current segmented harness.

[0056] In actual application, the harness schematic diagram can be viewed through preset software (such as E3 software), and the node triangle in the harness schematic diagram can be viewed through operation buttons in the software.

[0057] S104, searching for repeated initial node triangles on common harnesses between any two automobile harnesses.

[0058] In the embodiment, first, the node triangles passed by each automobile harness are taken as track identification points in the harness path to determine the harness path composed of node triangles. It can be understood that a complete automobile harness includes multiple segmented harnesses, and the node triangles marked on the segmented harnesses are taken as track identification points to generate the harness path composed of node triangles. In an example, the node triangle has a triangle number, thus, the triangle number can be used to represent the harness path; for example, the triangle numbers of three segmented harnesses on a certain automobile harness are 1, 2 and 3 respectively, thus, the automobile harness can be represented in the form of 1-2-3.

[0059] Second, searching for repeated initial node triangles on common harness paths between the first harness path and the second harness path; wherein, the first harness path and the second harness path are any two harness paths, that is, the first harness path and the second harness path are the harness paths corresponding to the any two automobile harnesses. In implementation, each node triangle on the first harness path can be compared with multiple node triangles on the second harness path to obtain the repeated initial node triangles between the first harness path and the second harness path.

[0060] In the embodiment, the segmented harness in the automobile harness is represented by the node triangle, thus, the repeated initial node triangles between any two automobile harnesses can represent the repeated segmented harnesses between the any two automobile harnesses, that is, the collinear harnesses. Therefore, the above-mentioned way of searching for common harnesses between any two automobile harnesses by using node triangles does not need to distinguish whether the collinear two automobile harnesses correspond to interference loops or sensitive loops, but can be applied to any two automobile harnesses, thereby avoiding missing the interference loops and the sensitive loops and improving the completeness of collinear searching.

[0061] S106, determine a target common line length of a common line between any two automobile harnesses according to a harness length of a segmented harness corresponding to the initial node triangle. For example, the harness lengths of the segmented harnesses corresponding to the initial node triangles can be superimposed, and the superimposed length is determined as the target common line length of the common line between the any two automobile harnesses.

[0062] The automobile harness common line checking method provided by the embodiment comprises: acquiring node triangles for representing segmented harnesses in automobile harnesses in a harness schematic diagram; finding repeated initial node triangles on a common line between any two automobile harnesses; and determining a target common line length of a common line between the any two automobile harnesses according to a harness length of a segmented harness corresponding to the initial node triangle. The present technical solution first represents the segmented harnesses in the automobile harnesses by the node triangles, and can represent the automobile harnesses with a large amount of information in segments by simple symbols (i.e. node triangles) without representing the harness types. Based on this, finding the repeated initial node triangles between any two automobile harnesses can represent the common line between the any two automobile harnesses. In this way, the node triangles are used to find the common line between any two automobile harnesses, without needing to distinguish whether the two automobile harnesses corresponding to the common line are interference loops or sensitive loops, but can be used to find the common line between any two automobile harnesses without distinction, thereby avoiding missing the interference loops and the sensitive loops and improving the completeness of the common line finding. In the case of a complete common line, determining the target common line length according to the harness length of the segmented harness corresponding to the initial node triangle can improve the calculation accuracy of the common line length.

[0063] According to the above embodiments, before acquiring the node triangles for representing the segmented harnesses in the automobile harnesses in the harness schematic diagram, the embodiment can first acquire a harness schematic diagram containing information such as automobile harnesses, harness information and node triangles, and refer to the following content.

[0064] Acquire a harness schematic diagram representing automobile harnesses.

[0065] Segment the automobile harnesses in the harness schematic diagram according to preset segmentation features, and divide each automobile harness into a plurality of segmented harnesses; wherein the segmentation features include but are not limited to: connection points (such as welding points, plug-in docking positions, junction box switching positions, etc.), branches, harness positions, and can refer to the examples of the segmentation features in Figure 2

[0066] Mark the node triangles and the harness information associated with the segmented harnesses, and number all the node triangles in the harness schematic diagram to obtain a triangle number of each node triangle.​

[0067] like Figure 2 As shown in the schematic diagram, on the segmented wiring harness of an automotive wiring harness, node triangles with triangular numbers are marked. This can be understood as... Figure 2 Only a small portion of the automotive wiring harness is shown. Considering that a node triangle is a geometric symbol indicating direction, this embodiment can use the direction of the node triangle to indicate the current direction of the segmented wiring harness. In one approach, wiring harness information can be associated with the triangle numbers of the node triangles in a table to represent the same segmented wiring harness. Wiring harness information includes, but is not limited to, the signal type, length, wire number, type of wiring harness, connected terminals, outer diameter, and color of the segmented wiring harness. As an example, the first column of the table is the triangle number, the second column is the wiring harness length, the third column is the wire number, and the fourth column is the signal type, etc.; the same row represents the interrelated triangle numbers and wiring harness information such as signal type, length, and wire number corresponding to the same segmented wiring harness.

[0068] The determination method for the signal type and harness type of segmented wiring harnesses can be described as follows. Based on the electromagnetic compatibility (EMC) characteristics of components within the vehicle, components are classified into sensitive source components and interference source components. In practical applications, components within the vehicle are categorized according to their EMC characteristics, primarily into sensitive source components and interference source components. Sensitive source components include sensor components, controller components without inductive loads, RF antenna components, and user experience components; interference source components include components involving high voltage, high current, inductive loads, and motors. Accordingly, the signal type corresponding to sensitive source components is determined as a sensitive source signal, and the harness type of the automotive wiring harness corresponding to the sensitive source signal is determined as a sensitive loop; similarly, the signal type corresponding to interference source components is determined as an interference source signal, and the harness type of the automotive wiring harness corresponding to the interference source signal is determined as an interference loop.

[0069] Each type of sensitive source signal corresponds to several types of sensitive circuits; for example, a sensitive source signal is a temperature sensor signal, and the corresponding sensitive circuits include: the outside room temperature sensor circuit (wire number FB633A), the air compressor temperature sensor circuit (wire number RB328), etc. Similarly, each type of interference source signal corresponds to several types of interference circuits; for example, an interference source signal is a seat back electric drive line signal, and the corresponding interference circuits include: the driver's seat back forward adjustment circuit (wire number FB510), the driver's seat back rearward adjustment circuit (wire number FB503), the front passenger seat back forward adjustment circuit (wire number RB513), the second-row left seat back forward adjustment circuit (wire number RB402), etc.

[0070] According to the wire harness schematic diagram in the preset software (such as E3 software), all node triangles or selected part of node triangles on the wire harness schematic diagram can be displayed according to the viewing operation of the user, and the wire harness information associated with the node triangle is displayed.

[0071] Based on the obtained wire harness schematic diagram, the embodiment can further include: searching and displaying a target automobile wire harness corresponding to a target wire number in the automobile wire harness of the wire harness schematic diagram according to the target wire number selected by the user.

[0072] In a specific example, as shown in Figure 3 , part of the automobile wire harness is shown, such as the front and rear adjustment wire harness of the main driver seat, the front and rear adjustment wire harness of the co-driver seat, the front and rear adjustment wire harness of the rear seat, and the height adjustment wire harness of the main driver seat, and the like. Each wire harness has its own wire number. For example, according to the target wire number MF104 selected by the user, the target automobile wire harness corresponding to MF104 is searched and displayed in the wire harness schematic diagram in a preset highlighting manner (such as highlighting, color differentiation, and flashing), as shown in Figure 3 , the target automobile wire harness corresponding to MF104 is represented by a thick line. It should be noted that Figure 3 the thick line is mainly used to compare and view the difference between the target automobile wire harness and other general automobile wire harnesses, and therefore, other information (such as triangle numbers) in the figure is not described in detail.

[0073] It can be understood that while the target automobile wire harness corresponding to the target wire number is displayed in the wire harness schematic diagram, the common wire harness between the other automobile wire harnesses and the target automobile wire harness can be obviously seen, and thus the wire harness length of the common wire harness between the two can be determined.

[0074] Based on the above embodiment, the embodiment provides a checking method for automobile wire harness common lines, including the following steps 1 to 4.

[0075] Step 1: obtaining node triangles used to represent segmented wire harnesses in the automobile wire harness in the wire harness schematic diagram.

[0076] Step 2: determining the node triangles passed by each automobile wire harness as a wire harness path.

[0077] Step 3: finding a repeated initial node triangle on a common wire harness between a first wire harness path and a second wire harness path; wherein the first wire harness path and the second wire harness path are any two wire harness paths.

[0078] In one implementation, the triangle numbers on the first wire harness path and the second wire harness path are found respectively; wherein the triangle number is used to uniquely identify the node triangle; the triangle numbers on the first wire harness path are compared with the triangle numbers on the second wire harness path to obtain a repeated initial triangle number; and the initial node triangle represented by the initial triangle number is determined.

[0079] Since the triangular number is used to represent the wire harness path, the embodiment can find the triangular numbers on the first wire harness path and the second wire harness path, respectively; for example, the triangular numbers found on the first wire harness path include 1, 2, 3, and 4, and the triangular numbers found on the second wire harness path include 5, 6, 2, and 7. It is found whether there is a repeated triangular number between the first wire harness path and the second wire harness path; if so, the initial triangular number (2) that is repeated is recorded, and it is determined that the initial node triangular 2 corresponding to the initial triangular number 2. The segmented wire harness corresponding to the initial node triangular 2 is a wire harness that is commonly passed through by the first wire harness path and the second wire harness path.

[0080] As Figure 2 and Figure 3 can be seen from the figure that there is a common wire harness and a repeated initial node triangular between the two wire harnesses. For example, Figure 2 The wire harness path represented by the node triangular with the triangular number 278 and 279 in Figure 3 , there is a common wire harness and a repeated initial node triangular between the main driver seat front and rear adjustment wire harness, the co-driver seat front and rear adjustment wire harness, the rear seat front and rear adjustment wire harness, and the main driver seat height adjustment wire harness.

[0081] Step 4, according to the wire harness length of the segmented wire harness corresponding to the initial node triangular, determine the target common length of the common wire harness between any two automobile wire harnesses.

[0082] The embodiment can copy or import the wire harness information associated with the initial node triangular into the excel table. When importing, the wire harness information associated with the initial node triangular can be determined according to the starting operation of the user on the preset import control, and the above wire harness information is stored in the excel table according to the preset row and column form. Then, based on the wire harness information stored in the table, the target common length between any two automobile wire harnesses is determined.

[0083] In one way, the wire harness length of the segmented wire harness corresponding to the initial node triangular can be directly accumulated, and the accumulated length is determined as the target common length between any two automobile wire harnesses. This way does not consider the wire harness type of the two wire harnesses, and not only contains known interference loops and sensitive loops, but also unknown loops that may have risks, ensuring the comprehensiveness of the check and improving the accuracy of the common length check.

[0084] In another way, first harness information pre-associated with the initial node triangle can be acquired, the first harness information including: signal type and harness length of the segmented harness. According to the signal type associated with the initial node triangle, the target node triangle corresponding to the signal type of the interference source signal or the sensitive source signal is screened from the initial node triangle; the target common length of the common harness between the first harness path and the second harness path is obtained by superimposing the harness length of the segmented harness corresponding to the target node triangle. This way can only check the common line of the interference loop and the sensitive loop with higher risk by screening the target node triangle corresponding to the interference source signal or the sensitive source signal, thereby improving the checking efficiency.

[0085] In the above two ways, the common line path and the common line length between any two harness routes can be recorded by a table.

[0086] After determining the target common line length between the first harness path and the second harness path, the method provided by the embodiment can further include: generating a harness common line risk prompt information in the case that the target common line length is greater than a preset length value.

[0087] Determining whether the target common line length between any two automobile harnesses is greater than a preset length value; if yes, it indicates that the common line between the two is too long, and the sensitive source type component and the interference source type component have a harness common line risk, in which case, a harness common line risk prompt information is generated to prompt the staff to improve the harness arrangement.

[0088] In summary, the automobile harness common line checking method provided by the present disclosure first acquires the node triangle in the harness schematic diagram, which can represent the automobile harness with a large amount of information in segments with a simple symbol (i.e. the node triangle) without representing the harness type; then the repeated initial node triangle between any two automobile harnesses is found, which can represent the common harness between the any two automobile harnesses; in this way, the node triangle is used to find the common line between any two automobile harnesses, without distinguishing whether the two automobile harnesses corresponding to the common line are the interference loop or the sensitive loop, but rather finding the common line for any two automobile harnesses, thereby avoiding missing the interference loop and the sensitive loop and improving the completeness of the common line finding. In the case of complete common harness, the target common line length between any two automobile harnesses is determined according to the harness length of the segmented harness corresponding to the initial node triangle, which can improve the calculation accuracy of the common line length. Further, according to the target common line length between the interference loop and the sensitive loop and other loops that may exist interference, the possible risk can be judged in advance, the forward design analysis and evaluation of the harness checking is carried out in the forward development process of the automobile, the problem points are found in advance, the subsequent test problems are reduced, the vehicle development speed is accelerated, and the development cycle is shortened.
