Description

Technical Field

[0001] This invention relates to the field of circuit diagram development in the automotive aftermarket, and in particular to a method and system for viewing the functional circuits of automotive electrical system schematics. Background Technology

[0002] With the rapid development of modern automotive electronics technology, the complexity and diversity of automotive electrical systems are constantly increasing. In the field of automotive repair, technicians need to accurately understand the principles and functional circuits of automotive electrical systems in order to quickly locate and repair problems when vehicle malfunctions occur. Therefore, system schematic diagrams are playing an increasingly irreplaceable role in the aftermarket repair field.

[0003] Viewing the system schematic diagram not only allows you to obtain basic information about the vehicle model and its configuration, as well as the working principles and connections of each circuit and electrical component, but also assists repair technicians in fault analysis when a vehicle experiences functional loss, helping them to identify fault detection points and procedures.

[0004] However, traditional system schematics are drawn manually or created using basic drawing software. These diagrams are usually quite large and complex. When repair technicians view system schematics, they need to identify each functional circuit in the schematic to systematically analyze faults and determine diagnostic solutions. This viewing and analysis process consumes a significant amount of time. Moreover, due to the continuous updates and improvements in automobiles, the variety of models, and the increasing types and number of system schematics, it becomes difficult to find and obtain the correct system schematics.

[0005] Furthermore, in traditional system schematics, the presentation of information for each functional circuit is relatively fixed, making it difficult to meet diverse maintenance needs. When maintenance technicians need to view a specific functional circuit, they must manually search and analyze the system schematic, which is not only time-consuming and laborious but also prone to errors.

[0006] Therefore, it is necessary to propose a more efficient and intelligent method for viewing the functional circuits of automotive electrical system schematic diagrams to address the problems existing in traditional methods. Summary of the Invention

[0007] In view of this, the present invention proposes a method and system for viewing functional circuits in automotive electrical system schematic diagrams. This method can automatically extract information from the system schematic diagram, create functional circuits, and intelligently illuminate and view each functional circuit in the schematic diagram, enabling repair technicians to quickly and accurately perform fault analysis and repair work. This method should be combined with modern computer technology to improve repair efficiency, reduce repair costs, and provide better automotive repair services.

[0008] To achieve the above objectives, in a first aspect, the present invention provides a method for viewing the functional circuits of an automotive electrical system schematic diagram, the method comprising the following steps:

[0009] Step 1: Extracting pin connection information from the system schematic diagram

[0010] In this step, wiring information is first extracted from reference materials such as wiring harness drawings, vehicle electrical schematics, fuse box schematics, and fuse box labels. This information includes drawing numbers, version numbers, wiring harness part numbers, node information, connector names, connector codes, pin numbers, wire numbers, wire colors, and wire diameters. By analyzing the number of pins in each wiring harness connector and the limiting slots in the connector graphic, the mating relationships between each wiring harness are determined, and the wiring information for the development vehicle model is output.

[0011] Step 2: Functional Loop Information Creation

[0012] In this step, a functional circuit creation module is created to store functional circuit information. Based on the functional principles required by the system schematic, primary function names are defined. For functions requiring further breakdown, secondary function names are defined based on the pin function information and primary function names in the system schematic. Next, the components included in each functional circuit are selected. Based on the pin function connection information extracted in step 1, the connector codes, nodes, pin numbers, wire numbers, wire colors, wire diameters, pin functions, fuse / relay names, fuse / relay numbers, and fuse / relay pin numbers in the functional circuits are supplemented. Furthermore, the lighting sequence of the functional circuits is defined based on the pin number flow order of the components through which current or signals flow in the functional circuit. The functional circuit creation module also needs to create functional circuit recommendation rules for creating functional circuit information for new vehicle models. By matching the combination information of all pin functions and components included in the created functional circuit information with the corresponding information in the pin connection relationship of the system schematic of the developing vehicle model, the matching circuit information is recommended and reused, thereby reducing the workload of manually creating functional circuit information.

[0013] Step 3: Check the function circuit lights up

[0014] In this step, a correspondence is created between the functional circuit information in each system schematic and the corresponding vector graphic elements, based on the system schematic name. Then, the functional circuit to be viewed is selected, and its graphic elements are highlighted according to the set illumination order. By verifying whether the highlighted portions of the system schematic form a complete functional circuit, the accuracy of the functional circuit creation can be checked. Simultaneously, when a vehicle malfunctions due to missing functions, this step assists technicians in quickly and accurately locating the corresponding functional circuit information from the circuit diagram, shortening the time spent consulting circuit diagrams for fault analysis, and improving repair efficiency.

[0026] As a further aspect of the present invention, when associating with the corresponding system schematic vector graphic elements, a correspondence between functional circuit information and the corresponding system schematic vector graphic elements is established based on the system schematic name. The functional circuit to be viewed is selected, and the graphic elements involved in the functional circuit are lit sequentially according to the lighting sequence information of the system schematic graphic elements set in the functional circuit, and then highlighted.

[0027] As a further aspect of the present invention, the order of lighting up the functional circuit is determined based on the pin number direction of the components through which the current or signal flows in the functional circuit. The graphic elements involved in lighting up the functional circuit include graphic elements such as power supply, fuse, relay, wire, connector, connector code, pin, node, and ground in the system schematic functional circuit.

[0028] Secondly, the present invention provides a system for viewing the functional circuit of an automotive electrical system schematic diagram, comprising:

[0029] Information Extraction Module: This module extracts pin connection information from the vehicle system schematic diagram from reference materials, including wiring information, development vehicle part information, and fuse box information.

[0054] When repair technicians view system schematics, they need to identify each functional circuit in the schematic to systematically analyze faults and determine diagnostic solutions. To improve the efficiency of technicians in viewing system schematics by visually displaying the information of each functional circuit, this invention proposes a method for viewing functional circuits in automotive electrical system schematics.

[0055] This invention provides a method and system for viewing functional circuits in automotive electrical system schematic diagrams. It extracts pin connection information from reference materials such as wiring harness drawings, vehicle electrical schematic diagrams, fuse box schematic diagrams, and fuse box labels. Functional circuit information is created based on this pin connection information and associated with corresponding vector graphic elements in the system schematic diagram. By setting the lighting order of the functional circuits, the graphic elements of each functional circuit in the system schematic diagram are highlighted, enabling rapid viewing of information for each functional circuit in the system schematic diagram.

[0056] By highlighting the graphic elements that constitute the functional circuits in the system schematic diagram, not only can the accuracy of the system schematic diagram be verified, but also, when a vehicle malfunctions due to missing functions, it can assist maintenance technicians in quickly and accurately finding the corresponding functional circuit information from the circuit diagram, shortening the time spent consulting the circuit diagram for fault analysis, and improving maintenance efficiency.

[0057] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] See Figure 1 As shown in the figure, this invention provides a method for viewing the functional circuits of an automotive electrical system schematic diagram. The method includes the following steps:

[0059] Step S10: Extract the pin connection information of the whole vehicle system schematic diagram from the reference materials.

[0060] In this embodiment, the reference materials include wiring harness drawings, vehicle electrical schematic diagrams, fuse box schematic diagrams, and fuse box labels. The extracted vehicle system schematic diagram pin connection information includes wiring information, vehicle model part information, and fuse box information. By integrating the wiring information, vehicle model part information, and fuse box information, pin connection relationships are created based on wire numbers, and the vehicle system schematic diagram pin connection information is output.

[0061] The process of extracting wiring information includes extracting wiring harness information and pin function information. Extracting wiring harness information involves extracting the wiring harness drawing number, version number, part number, and version number from the wiring harness drawing reference materials, as well as extracting node information, connector names, connector codes, pin numbers, wire numbers, wire colors, and wire diameter information from the wiring harness drawings. Extracting pin function information involves extracting the corresponding pin function information from the vehicle electrical schematic reference materials based on the connector codes and pin numbers. During wiring information extraction, the interlocking relationship between wiring harnesses is determined by analyzing the number of pins in each wiring harness connector and the limiting groove information in the connector graphic, and the wiring information for the developed vehicle model is output.

[0062] The extracted vehicle model parts information consists of component information extracted from reference materials such as wiring harness drawings, vehicle electrical schematics, fuse box schematics, and fuse box labels. This includes the correspondence between connector names and component names, as well as the component part numbers and version numbers.

[0063] When extracting fuse box information, the fuse box information, including fuse box name, fuse / relay name, fuse / relay number, fuse / relay pin information, and fuse / relay type, is extracted by combining the wiring harness diagram with the fuse box label, vehicle electrical schematic diagram or fuse box schematic diagram in the reference materials.

[0064] Step S20: Create functional circuit information based on the pin connection information of the vehicle system schematic diagram, and associate it with the vector graphic elements of the corresponding system schematic diagram.

[0065] In this embodiment, when creating functional loop information, the functional loop creation module stores the functional loop information. The functional loop creation module is also used to define the first-level function name and the second-level function name, create the names of each functional loop included in the functional loop information according to the second-level function name, define the functional loop type, complete the creation of the correspondence between the circuit diagram directory framework and the functional loop name, and create functional loop recommendation rules.

[0066] Among them, the functional loop recommendation rule is used to match the information of the created functional loop, recommend and reuse the existing loop information. When matching the information of the created functional loop, the combination information of all pin functions and components contained in the created functional loop information is matched one by one with the corresponding information in the pin connection relationship of the schematic diagram of the vehicle system.

[0067] Step S30: Set the lighting order of the functional circuits in the functional circuits, highlight the graphic elements of each functional circuit in the system schematic diagram, and quickly view the information of each functional circuit in the system schematic diagram.

[0068] In this embodiment, when associating with the corresponding system schematic vector graphic elements, a correspondence between functional circuit information and the corresponding system schematic vector graphic elements is established based on the system schematic name. The functional circuit to be viewed is selected, and the graphic elements involved in the functional circuit are lit up sequentially according to the lighting order information of the system schematic graphic elements set in the functional circuit, and then highlighted.

[0069] The order in which the functional circuits are lit is determined based on the pin numbers of the components through which the current or signal flows in the functional circuit. The graphic elements involved in lighting up the functional circuits include the power supply, fuse, relay, wire, connector, connector code, pin, node, and grounding elements in the functional circuit of the system schematic diagram.

[0070] Through the above steps, the method for viewing functional circuits in automotive electrical system schematic diagrams of the present invention realizes the intelligent generation and efficient viewing of information on each functional circuit in the system schematic diagram, improving the work efficiency of maintenance technicians, and ensuring the accuracy of system schematic diagrams and functional circuit information.

[0071] This invention provides a method for viewing the functional circuits of an automotive electrical system schematic diagram, the specific steps of which are as follows:

[0072] Step 1: Extracting pin connection information from the system schematic diagram

[0073] In this step, wiring information is first extracted from reference materials such as wiring harness drawings, vehicle electrical schematics, fuse box schematics, and fuse box labels. This information includes drawing numbers, version numbers, wiring harness part numbers, node information, connector names, connector codes, pin numbers, wire numbers, wire colors, and wire diameters. By analyzing the number of pins in each wiring harness connector and the limiting slots in the connector graphic, the mating relationships between each wiring harness are determined, and the wiring information for the development vehicle model is output.

[0074] Specifically, it includes:

[0075] Step 1.1: Extraction of Line Information

[0076] Manually extract wiring harness information from the wiring harness drawing reference materials, including the drawing number, version number, part number, and version number, as well as node information, connector names, connector codes, pin numbers, wire numbers, wire colors, and wire diameters. Based on the connector codes and pin numbers, extract the corresponding pin function information from the vehicle electrical schematic reference materials.

[0077] By analyzing information such as the number of pins and the limiting slots of each wiring harness connector, the interlocking relationship between each wiring harness is determined, and the wiring information of the developed vehicle model is output.

[0078] Step 1.2: Extracting Parts Information for Vehicle Models

[0079] Extract the corresponding component names from the connector names and establish a mapping between connector names and component names. Compare the component names with the part names in the vehicle assembly list to find the component part number and part version number. For components with the same name corresponding to multiple part numbers, further distinguish and determine the part number and part version number of each component by manually analyzing supplier information, vehicle model level information, and intermediate connector information, thus completing the extraction of part information for the developed vehicle model.

[0080] Step 1.3: Extracting information from the safe box

[0081] Based on the wiring harness drawings and reference materials, including fuse box labels, vehicle electrical schematics, and fuse box schematics, we manually extracted fuse box information such as fuse box name, fuse / relay name, fuse / relay number, fuse / relay pin information (pin number, wire number, wire color, wire diameter), and fuse / relay type.

[0082] Step 1.4: Generation of System Schematic Pin Connection Information

[0083] The circuit information extracted in step 1.1, the component information extracted in step 1.2, and the fuse box information extracted in step 3 are integrated, and pin connection relationships are created according to the wire numbers to output the pin connection information of the whole vehicle system schematic diagram.

[0084] Step 2: Functional Loop Information Creation

[0085] In this step, a functional circuit creation module is created to store functional circuit information. Based on the functional principles required by the system schematic, primary function names are defined. For functions requiring further breakdown, secondary function names are defined based on the pin function information and primary function names in the system schematic. Next, the components included in each functional circuit are selected. Based on the pin function connection information extracted in step 1, the connector codes, nodes, pin numbers, wire numbers, wire colors, wire diameters, pin functions, fuse / relay names, fuse / relay numbers, and fuse / relay pin numbers in the functional circuits are supplemented. Furthermore, the lighting sequence of the functional circuits is defined based on the pin number flow order of the components through which current or signals flow in the functional circuit. The functional circuit creation module also needs to create functional circuit recommendation rules for creating functional circuit information for new vehicle models. By matching the combination information of all pin functions and components included in the created functional circuit information with the corresponding information in the pin connection relationship of the system schematic of the developing vehicle model, the matching circuit information is recommended and reused, thereby reducing the workload of manually creating functional circuit information.

[0086] Specifically, it includes:

[0087] Step 2.1: Create a functional loop creation module to store functional loop information.

[0088] In the functional loop creation module, the first-level function name is defined according to the functional principle content to be explained in the system schematic diagram; for functions that need further functional breakdown, the second-level function name is defined according to the pin function information and the first-level function name in the system schematic diagram; the names of each functional loop contained in the second-level function are created and the functional loop type is defined (the types include: signal loop and execution loop), thus completing the creation of the correspondence between the circuit diagram directory framework and the functional loop name.

[0089] For example: When the circuit diagram needs to illustrate the functional principle and wiring relationships of the "windshield wiper system", the system schematic diagram name can be defined as:

[0090] windshield wiper system

[0091] The primary function name can be divided into: rear wiper operation;

[0092] The secondary function names can be divided into: rear wiper control (signal circuit) and rear wiper washer (execution circuit).

[0093] Step 2.2: Select the components included in each functional circuit. Based on the system schematic pin function connection information extracted in Step 1.4, supplement the information of the functional circuit with elements such as connector code, node, pin number, wire number, wire color, wire diameter, pin function, fuse / relay name, fuse / relay number, and fuse / relay pin number. Define the lighting sequence of the functional circuit based on the pin number flow order of the components through which the current or signal flows in the functional circuit, and complete the creation of information for each functional circuit.

[0094] In the functional loop creation module, recommended rules for functional loops are created. When creating functional loop information for a new vehicle model, the module matches the combination information of all pin functions and components (part numbers, version numbers) contained in the created functional loop information with the corresponding information in the pin connection relationship of the system schematic diagram of the developed vehicle model. The functional loop creation module recommends and reuses the matched loop information to reduce the workload of manually creating functional loop information.

[0095] Step 3: Check the function circuit lights up

[0096] In this step, a correspondence is created between the functional circuit information in each system schematic and the corresponding vector graphic elements, based on the system schematic name. Then, the functional circuit to be viewed is selected, and its graphic elements are highlighted according to the set illumination order. By verifying whether the highlighted portions of the system schematic form a complete functional circuit, the accuracy of the functional circuit creation can be checked. Simultaneously, when a vehicle malfunctions due to missing functions, this step assists technicians in quickly and accurately locating the corresponding functional circuit information from the circuit diagram, shortening the time spent consulting circuit diagrams for fault analysis, and improving repair efficiency.

[0097] Specifically:

[0098] Based on the system schematic name, create a correspondence between the functional circuit information in each system schematic and the corresponding vector graphic elements of the system schematic. Select the functional circuit to be viewed, and according to the lighting order information of the system schematic graphic elements set in the functional circuit, highlight the graphic elements such as power supply, fuse, relay, wire, connector, connector code, pin, node, and ground in the system schematic functional circuit in sequence.

[0099] By verifying whether the illuminated portions of the system schematic diagram form a complete functional circuit, the accuracy of the functional circuit creation can be checked. Similarly, by checking whether there are any areas in the system schematic diagram that cannot be illuminated by any functional circuit, the accuracy of the schematic diagram drawing can be verified. Creating and illuminating functional circuits not only verifies the accuracy of the system schematic diagram but also allows maintenance technicians to accurately locate the functional circuit information for each function when reviewing the circuit diagram, assisting in troubleshooting circuit faults.
