These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0050] First, the terms involved in this application are explained:
[0051] Wiring harness: refers to a component that is formed by crimping the connectors made of copper material and the wires together to form a wiring harness to connect the circuit. Each wiring harness can also be called a wiring harness branch, and each wiring harness can include multiple wires. It is understood that the wiring harness of a vehicle includes multiple wiring harnesses that connect various devices. Each wiring harness has two ends, both of which are connected to at least two other wiring harness branches, or one end is not connected to the wiring harness branch.
[0052] In recent years, with the rapid development of the vehicle industry, the iteration speed of vehicle products has become faster and faster. Therefore, how to shorten the vehicle R&D cycle is crucial for automobile companies. An important part of the vehicle R&D process is the design of the vehicle wiring harness. The design of the vehicle wiring harness is mainly divided into wiring harness principle design, topology design, three-dimensional design, and two-dimensional design. Among them, the wiring harness principle design is to design the connection logic between the vehicle's equipment, which is the core of the wiring harness design.
[0053] However, as more and more electronic control modules and sensors are applied to vehicles, the increase of these electronic control modules and sensors has undoubtedly improved the comfort and safety of the vehicle, but it has also made the wiring harness structure of the vehicle more and more complex (for example, the wiring harness loops are basically maintained at more than 1,000). Therefore, with the increase in the number of vehicle wiring harness loops, it is also a difficult problem for engineers to draw the vehicle wiring harness schematic diagram. Although engineers can use the wiring harness principle design software to complete the design task of the wiring harness schematic diagram, the existing mainstream wiring harness principle design software is of limited help to engineers in designing the wiring harness original diagram. It requires engineers to manually create devices in the wiring harness principle design software, manually create connection information between devices, and manually define the properties of the wiring harness between devices before generating the vehicle wiring harness schematic diagram.
[0054] Combining the above scenarios, it can be seen that in the prior art, by using the existing mainstream wiring harness principle design software to assist engineers in designing wiring harness schematics, there are technical problems such as low automation, high labor input, and long design cycle.
[0055] The method for generating a wiring harness schematic diagram provided in the present application solves the technical problem of low efficiency in wiring harness schematic design by pre-storing design parameters that can characterize the circuit structure in a design parameter library, and directly retrieving the design parameters from the design parameter library when the wiring harness schematic diagram needs to be generated. The wiring harness schematic diagram is automatically generated according to the design parameters by means of a technical means.
[0056] Exemplarily, the execution subject of the present application may be an electronic device, or a terminal device, or a server, or an apparatus or device that can execute the solution of the present application, without limitation.
[0057] The following uses the execution subject as an example of a server to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0058] Figure 1 Schematic diagram of the process of generating the wiring harness schematic diagram provided in this application Figure 1 ,like Figure 1 As shown, the method includes:
[0059] S101, obtaining target structure information.
[0060] It should be understood that a wiring harness schematic diagram generally includes a plurality of circuit structures, each of which includes devices having a connection relationship, and the circuit structure can realize corresponding functions, such as a brake light function or a turn signal function.
[0061] Exemplarily, the above-mentioned target structure information refers to the target circuit structure required for the wiring harness schematic to be generated. It should be noted that the target structure information can be the entire circuit structure of the vehicle, or it can be a partial circuit structure, and can be set according to actual needs. Each circuit structure can have an identifier of structural information, which is used to uniquely characterize the circuit structure. The identifier of the structural information can be, for example, an ID pre-assigned by the server, or it can be the name of the function or the description information of the function, such as a certain model of vehicle brakes, a certain brand of refrigeration equipment, etc., which can be used to uniquely characterize the function of a circuit structure, and the embodiments of the present application are not limited here.
[0062] In a possible implementation manner, the server may communicate with other electronic devices to obtain target structure information, or may receive target structure information input by a user.
[0063] In another possible implementation, the server may obtain the wiring harness configuration information of the vehicle, wherein the wiring harness configuration information may indicate the identification of the target structure information. Exemplarily, the method for generating the wiring harness schematic diagram provided in this embodiment may be executed by a wiring harness diagram generation module, which may receive the wiring harness configuration information input by the designer according to the design requirements of the vehicle wiring harness system. For example, the wiring harness diagram generation module may have an input module (such as a touch display, a keyboard or a mouse, etc.), and the designer may input the wiring harness configuration information through the input module.
[0064] For example, the wiring harness configuration information can be a table, and the identifier of the target structure information is placed in the cell of the table. Of course, the wiring harness configuration information can include the identifier of the structure information corresponding to the entire circuit structure of the vehicle, or it can be the identifier of the structure information corresponding to a part of the circuit structure of the vehicle. Refer to Table 1, which is a schematic diagram of a wiring harness configuration information provided by the present application. Among them, structure information 1, structure information 2 and structure information 3 are the identifiers of the target structure information, which is only a schematic diagram and is not limited here.
[0065] Table 1 Harness configuration information
[0066]
[0067] S102: Determine design parameters corresponding to the target structure information according to the target structure information and a preset design parameter library.
[0068] Exemplarily, the design parameter library includes at least one design parameter corresponding to structural information. The design parameter is used to indicate the device information of the device included in the circuit structure, and the connection information between the devices, wherein the device information may include, for example, the name of the device or the ID of the device, and the connection information is used to characterize the connection relationship between the devices, and the properties of the connecting wires used between the devices, which may include, for example, hole position information, loop information, wire diameter or wire type on the device. The design parameter corresponding to the target structural information is used to indicate the device information of the device included in the target circuit structure, and the connection information between the devices.
[0069] It is understandable that the wiring harness systems of the same type of vehicles are basically the same, the difference is that the wiring harness systems of high-level vehicles have more functions, and the wiring harness systems of low-level vehicles have fewer functions. For example, the configuration of the same type of vehicle can include standard or advanced types. The standard type vehicle is not equipped with a wireless fidelity (Wireless Fidelity, WIFI) function, and the advanced type vehicle is equipped with a WIFI function. Therefore, the number of circuit structures that realize the function is different, that is, the number of structural information is different. However, the circuit structure corresponding to the same structural information is the same, so the design parameter library can store design parameters corresponding to the structural information of vehicles of various types and levels. When the wiring harness schematic diagram of the vehicle is to be designed, the circuit structure corresponding to the structural information that may be stored in the design parameter library is the same as the multiple circuit structures required by the vehicle. Then, when the wiring harness schematic diagram of the vehicle needs to be generated, the design parameters corresponding to the required structural information of the vehicle can be directly selected from the design parameter library according to the required structural information. It is also possible that the newly designed vehicle will have some improvements relative to the already developed vehicle. At this time, the designer needs to add the design parameters corresponding to the new structural information of the newly designed vehicle to the design parameter library.
[0070] Therefore, the server can determine the design parameters corresponding to the target structure information from the preset design parameter library according to the target structure information. Referring to Table 2, Table 2 is a schematic diagram of a design parameter library provided by the present application. Therefore, the identifier that matches the identifier of the target structure information can be searched in the design parameter library, and the design parameters corresponding to the matched identifier are used as the design parameters corresponding to the target structure information.

[0073] S103: Generate a wiring harness schematic diagram according to design parameters corresponding to the target function information.
[0074] Exemplarily, the wiring harness schematic diagram is used to describe the circuit structure corresponding to each function. The wiring harness schematic diagram may include information such as the logical connection relationship between devices in the vehicle, wire information between devices, names of each device, and other necessary specification definitions.
[0075] For example, the design parameters corresponding to the above-mentioned target structure information can indicate the device information of the devices included in the target circuit structure, as well as the connection information between the devices. In other words, it can indicate the circuit structure diagram. Therefore, a wiring harness schematic diagram can be generated based on the design parameters corresponding to the target structure information.
[0076] Compared with the disadvantages of the related art that when developing a vehicle wiring harness diagram, a large amount of schematic diagram content needs to be drawn, the workload is large, and the development time is long, the generation method of the wiring harness schematic diagram provided by the embodiment of the present invention can achieve the purpose of simplifying the development process of the vehicle wiring harness schematic diagram, and achieve the technical effect of saving the development time of the vehicle wiring harness schematic diagram, thereby solving the technical problem of low efficiency of the development process of the vehicle wiring harness schematic diagram in the related art and improving the development efficiency of the vehicle wiring harness schematic diagram.
[0077] The method for generating a wiring harness schematic provided in the embodiment of the present application obtains the target structure information, and queries a preset design parameter library according to the target structure information to obtain the design parameters corresponding to the target structure information. Since the design parameters corresponding to the target structure information are device information that characterizes the devices included in the target circuit structure, as well as the connection information between the devices, the wiring harness schematic can be automatically generated according to the design parameters corresponding to the target structure information. Compared with manually drawing a connection relationship diagram between devices, in the scheme of the present application, the design parameters corresponding to the target structure information are defined in advance in a preset design parameter library. It is only necessary to determine the circuit structure included in the wiring harness schematic to be generated, and the corresponding design parameters can be retrieved through the design parameter library to generate the wiring harness schematic, thereby simplifying the wiring harness schematic design process and achieving the technical effect of saving the design time of the vehicle's wiring harness schematic, thereby improving the production efficiency of the vehicle.
[0078] The design parameter library is described in detail below.
[0079] The connection logic of the wiring harness is the core design content of the vehicle wiring harness system, and it is also the part that consumes a lot of man-hours in the wiring harness schematic design process. Based on this, the design parameters in the design parameter library can at least indicate the device information of the device, as well as the connection information between devices. The connection information may include: the wiring harness information required for the implementation of the connection logic (wire diameter or wire type), connectors on the device (hole position information), loop information, etc.
[0080] Optionally, the design parameters include: the name of the head-end device, the description of the head-end hole position, the name of the end-end device, the description of the end-end hole position, the loop number, the properties of the harness used between devices, and the fuse information, wherein the head-end hole position description is the description of the hole position of the connector on the device, the end-end hole position description is the description of the plug-in hole position on the device, the connector is directly connected to the device or is located on the device, and the harness between the devices is connected to the connector of the device to achieve the connection between the devices. The loop number is numbered according to the connector of the device, that is, a pair of head-end hole position description and end-end hole position description corresponds to a loop number. The properties of the harness include but are not limited to the wire color, wire diameter, and type of the wire. The wire color can refer to the color corresponding to the wire displayed in the topology diagram, or it can also refer to the color of the wire used in the actual wiring. Fuse information can include but is not limited to fuse type, fuse capacity, etc. The fuse type is the fuse type required by the device, which is divided into box type and plug-in type; the fuse capacity is the fuse capacity required by the device, which can be divided into 10A, 20A, etc.
[0081] Optionally, the design parameters may also include a drawing page name and a functional description. The drawing page name is used to indicate the location where the circuit structure diagram is generated, and the functional description is used to indicate the function implemented by the circuit structure, so that engineers can quickly search in the design parameter library and maintain its changed versions.
[0082] Exemplarily, the design parameter library is a database storing multiple design parameters, and a data item in the database is a design parameter of a structural information. Optionally, the design parameter library can be stored in the wiring harness diagram generation module, or in other devices, or in the Internet, such as the cloud. The wiring harness diagram generation module can retrieve the design parameter of the structural information from the design parameter library according to the structural information.
[0083] Refer to Table 3, which is a schematic diagram of a design parameter library provided by the present application. Table 3 is merely a schematic diagram of structure information 1 and structure information 2.

[0086] Referring to the design parameter library shown in Table 3, each structure information in the table corresponds to two design parameters. This is because the circuit structure corresponding to the structure information has two loops. Figure 3 and Figure 4 As shown, therefore, the design parameter library includes all design parameters corresponding to the structure information, and each column can be regarded as a loop information. It should be noted that the fuse information is not listed in Table 3, and the embodiment of the present application is not limited here. It can be set according to actual needs. The design parameter library can also include other information. The embodiment of the present application only provides an illustration of a design parameter library.
[0087] In some embodiments, the whole vehicle can be split based on its functions to obtain multiple circuit structures, each of which has a minimum circuit connection structure. For example, the horn, cigarette lighter, GPS or brake and other devices that realize basic functions can be respectively composed of a circuit structure that can realize the corresponding function with their corresponding controllers, and each circuit structure has structural information. Each circuit structure here is obtained by dividing a single subsystem of the vehicle wiring harness according to functional logic. Here, the subsystem is a set of devices that realize a specific function, and a single system can be the interconnection between the controller, sensor, and actuator. The controller and the actuator can form a circuit structure, and the sensor and the controller can form another circuit structure. Multiple devices that perform the same function can form a circuit structure with the controller alone. For example, the front lights of the vehicle and the controller form a circuit structure, and the rear lights of the vehicle and the controller form a circuit structure. For another example, the brake devices of the two front wheels can each form a circuit structure with the brake control device.
[0088] Exemplarily, after the multiple subsystems of the vehicle wiring harness are split into a circuit structure, the identification of the structural information and the design parameters of the circuit structure can be obtained, and a mapping relationship between the identification of the structural information and the design parameters is established in the design parameter library.
[0089] In some possible implementations, the design parameter library corresponds to a circuit structure diagram of each structure information. Figure 3 and Figure 4 As shown, Figure 3 A schematic diagram of a circuit structure provided in this application is shown in FIG. Figure 4 A schematic diagram of another circuit structure diagram provided by the present application. The circuit structure diagram may include a block diagram of the devices included in the circuit structure corresponding to the structure information and a connection loop diagram between the devices. Therefore, according to the target structure information, the design parameters corresponding to the target structure information are obtained from the design parameter library, and the design parameters are added to the corresponding positions of the circuit structure diagram corresponding to the structure information to generate the wiring harness schematic diagram without the need for repeated manual drawing and modification.
[0090] In this embodiment, the design parameters corresponding to the structural information are defined in advance, which means that as long as the data in the design parameter library is not changed, any design engineer, when designing a wiring harness schematic, will have the same wiring harness properties for the circuit structure corresponding to the same structural information on the wiring harness schematic, such as loop number, wire color, wire type, wire diameter, multi-core wire, etc. Thus, the consistency of the circuit structure corresponding to the same structural information in different wiring harness schematics is ensured. At the same time, the time required to manually create equipment, define equipment names, define hole positions, and define wires for the circuit structure corresponding to each structural information is saved during design.
[0091] Figure 2 Schematic diagram of the process of generating the wiring harness schematic diagram provided in this application Figure 2 ,like Figure 2 As shown, the method includes:
[0092] S201. Obtain wiring harness configuration information of a vehicle.
[0093] Exemplarily, the wiring harness configuration information includes an identifier of the target structure information, for example, the wiring harness configuration information may be received from a user, or the wiring harness configuration information may be acquired by communicating with other electronic devices.
[0094] S202, searching the design parameter library for an identifier that matches the identifier of the target structure information in the harness configuration information, and determining a design parameter that has a mapping relationship with the matched identifier as the design parameter corresponding to the target function information.
[0095] Exemplarily, this step refers to the above-mentioned step S101 and will not be described in detail.
[0096] S203 . Generate a target circuit structure diagram on a drawing page corresponding to the target structure information according to design parameters corresponding to the target structure information.
[0097] Exemplarily, the design parameters corresponding to the target structure information also include a drawing page corresponding to the target structure information, and the drawing page indicates the location where the target circuit structure diagram is generated. Furthermore, the target circuit structure diagram can be generated on the drawing page corresponding to the target structure information according to the design parameters corresponding to the target structure information. The generated target circuit structure diagram can be, for example, referenced to Figure 3 or Figure 4 shown.
[0098] In this way, the target structure information can be identified according to the acquired wiring harness configuration information, and a target circuit structure diagram corresponding to the target structure information can be drawn on a drawing page corresponding to the target structure information.
[0099] S204, associating the same objects in different target circuit structure diagrams to obtain a wiring harness schematic diagram.
[0100] Exemplarily, the above-mentioned object may be a device, or a connecting wire.
[0101] It should be understood that after the wiring harness schematic is paginated, each drawing page may include several circuit structure diagrams, which may include the same equipment or connecting wires. Therefore, the same equipment or connecting wires can be merged together by merging the circuit structure diagrams, making the circuit structure diagram more concise and increasing the utilization rate of the drawing pages. The circuit structure diagram merger can also improve the overall readability of the drawing. The circuit structure diagram merger mainly merges equipment and connecting wires. After the merger, other elements in the circuit structure diagram need to be adaptively adjusted, such as the reconstruction of logic signal connections and the re-marking of drawing information. After multiple rounds of iterations, the circuit structure diagram merger ends until the equipment or connecting wires on the drawing can no longer be merged.
[0102] In one example, step S204 includes the following process:
[0103] If it is determined that different circuit structure diagrams on the same drawing page have the same equipment, the same equipment will be merged into one equipment.
[0104] If it is determined that the circuit structure diagrams on different drawing pages have the same connecting wires, a connection diagram of the same connecting wires is generated on the different drawing pages to obtain a wiring harness schematic diagram.
[0105] If it is determined that the circuit structure diagrams on different drawing pages have the same equipment, an association relationship between the same equipment is established.
[0106] For example, Figure 3 and 4 As shown in the figure, the parts with the same functions and attributes in the circuit structure diagram are merged, and the elements in the merged circuit structure diagram are adjusted accordingly, which solves the problem that the information on the drawing is scattered and affects the readability of the drawing. Figure 1 And circuit structure Figure 2 They are all placed on page 1 and have the same equipment, so the circuit structure diagram needs to be merged. Figure 5 As shown, Figure 5 This is a schematic diagram of a wiring harness provided in this application. After one round of iteration, the circuit structure Figure 1 And circuit structure Figure 2 The same device (device 1) completes the same-side merge, and the loop identifiers on the devices are updated.
[0107] S205. Add device interface information to the device in the wiring harness schematic diagram to obtain an updated wiring harness schematic diagram.
[0108] Exemplarily, the above-mentioned device interface information is used to indicate the interface on the device included in the target circuit structure and the attribute information of the interface.
[0109] Exemplarily, the interface information corresponding to the target structure information is first derived from the device interface information (interface control document, referred to as ICD information) system, and according to the device name and loop number and hole description of the wiring harness schematic diagram, the system ID, Chinese name, connector name, wiring harness side connector model, hole number, hole working voltage, hole steady-state current, twisted pair, shielding, plating and other interface information in the interface information library are automatically mapped with the entries in the design parameter library. For example, Table 4 is a schematic diagram of an interface information library provided in an embodiment of the present application.
[0110] Table 4 Interface information library
[0111]
[0112]
