Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0040] The following describes the method and device for estimating the cost of an automotive wiring harness according to the embodiments of the present application. In view of the problem in the related art mentioned in the above background art that for the method of estimating the cost of a vehicle wiring harness, it is impossible to quickly, efficiently and reasonably analyze and estimate the wiring harness cost according to the implementation plan of the vehicle's functional requirements in the stage where the wiring harness drawings have not been developed and the specific material information of the wiring harness composition has not been given, and it is difficult to meet the analysis and estimation requirements of the wiring harness cost in the initial stage of the project. The present application provides a method for estimating the cost of an automotive wiring harness. In this method, based on the topology of the vehicle's entire wiring harness, the segmented cost information and loop composition of different wiring harness application areas can be determined, and the cost change of the wiring harness can be quickly estimated. Thus, in the project planning and product definition stages, when the wiring harness drawings have not been developed and the specific material information of the wiring harness composition has not been given, the evaluation and analysis of the wiring harness cost can be effectively and quickly carried out according to the implementation plan of the vehicle's functional requirements, the evaluation efficiency of the wiring harness cost can be improved, and combined with the cost data information composition of the previous historical models of the same platform, a more accurate calculation of the wiring harness cost can be carried out, and thus a design cost basis can be provided for the development concept of the vehicle's electrical system. Thus, the problems in the related art that for the method of estimating the cost of a vehicle wiring harness, it is impossible to quickly, efficiently and reasonably analyze and estimate the wiring harness cost according to the implementation plan of the vehicle's functional requirements in the stage where the wiring harness drawings have not been developed and the specific material information of the wiring harness composition has not been given, and it is difficult to meet the analysis and estimation requirements of the wiring harness cost in the initial stage of the project are solved.

[0041] Specifically, Figure 1 is a flowchart of a method for estimating the cost of an automotive wiring harness provided by an embodiment of the present application.

[0042] As Figure 1 shown, the method for estimating the cost of the automotive wiring harness includes the following steps:

[0043] In step S101, in the vehicle project planning stage or the vehicle product definition stage, obtain the topology of the vehicle's entire wiring harness.

[0044] It can be understood that the topology of the vehicle's entire wiring harness here refers to the connection relationship and layout method between the vehicle's entire wiring harness and each electrical component in a graphical or abstract way, showing information such as the wiring harness's routing, branching situation, and connection points with each electrical system part.

[0045] In some embodiments, during the vehicle project planning or product definition phase, the present application can analyze and obtain the overall vehicle wiring harness topology structure, thereby enabling an understanding of the layout and connection relationships of the vehicle wiring harness at a macroscopic level. By analyzing the positions of various electrical components in the vehicle and their electrical connection requirements, the routing, branch points, and connection methods with each component of the wiring harness are determined, and the topology structure of the wiring harness is constructed. This can provide an overall grasp of the vehicle's electrical system at an early stage and lay a foundation for subsequent cost assessment.

[0046] Taking an electric vehicle as an example, during the project planning phase, engineers first determine the positions of the main electrical components such as the battery, motor, electric control system, headlights, instrument panel, in-vehicle entertainment system, etc. Then, based on the functions and electrical connection requirements of these components, the routing of the wiring harness is planned. For example, a high-current wiring harness is required to transmit power from the battery to the motor, and this wiring harness will pass through some specific positions and may have branches connected to sensors for monitoring the battery and motor states. Corresponding wiring harness connections are also required from the vehicle power supply to each headlight to form a complete wiring harness topology structure.

[0047] The embodiments of the present application can preliminarily estimate the length and complexity of the wiring harness based on the topology structure. Without specific material information, the wiring harness usage can also be roughly judged, thereby providing a preliminary cost assessment. Moreover, the topology structure constructed by the embodiments of the present application can analyze the wiring harness connection relationships between different functional modules, quickly identify the critical paths and high-cost areas, provide a direction for optimized design, and help evaluate the impact of the overall vehicle function implementation scheme on the wiring harness cost. For example, when adding a new function, the new requirements and cost changes for the wiring harness can be quickly judged through the topology structure.

[0048] Optionally, in an embodiment of the present application, obtaining the overall vehicle wiring harness topology structure includes: collecting at least one of the overall vehicle equipment definition, implementation schemes of each electrical system involved in the vehicle, and information on the layout positions of relevant parts; and generating the overall vehicle wiring harness topology structure based on the at least one.

[0049] It can be understood that the overall vehicle equipment definition here refers to the detailed definition and description of various equipment, devices, their functions, specifications, etc. equipped on the vehicle as a whole, including but not limited to engine type, transmission form, presence or absence of a sunroof, audio system configuration, etc.

[0050] The implementation schemes of the electrical systems involved in the vehicle can be understood here as the specific technical implementation methods and design ideas for each electrical system in the vehicle, such as the power supply system, lighting system, control system, etc., including but not limited to the electronic components used, circuit principles, control strategies, etc.

[0051] The part layout position information here refers to the specific installation positions and spatial distributions of various components in the vehicle within the body, such as the specific positions of the battery, motor, sensors, controller, etc. in the vehicle.

[0052] In some embodiments, in order to construct the vehicle wiring harness topology, the present application can collect at least one of the vehicle equipment definition of the vehicle, the implementation solutions of each electrical system involved in the vehicle, and the part layout position information, and use it as the basis for constructing the vehicle wiring harness topology.

[0053] Among them, the vehicle equipment definition determines which electrical equipment and functions are required, thereby determining the objects to be connected by the wiring harness and the types of signals carried. The implementation solutions of the electrical systems involved in the vehicle clarify the logical relationships and electrical connection requirements between the electrical equipment of the vehicle, providing a connection basis for the wiring harness topology. The part layout position information determines the signal loop path of the wiring harness.

[0054] Then, based on the information collected, the embodiments of the present application can analyze the connection requirements and position relationships between each electrical component, and use certain logic and rules to plan and design the connection points of each component with the wiring harness, the branches and directions of the wiring harness, etc., and finally generate the vehicle wiring harness topology to intuitively display the connection architecture of the vehicle electrical system.

[0055] For example, in the initial stage of a compact car project, it is determined in the vehicle equipment definition that equipment such as an automatic air conditioning system, a rear view camera system, and a keyless entry system are equipped. In the implementation solution of the electrical system, the automatic air conditioning system requires components such as a temperature sensor, a control module, and an air conditioning compressor to be connected to each other to achieve the function; the rear view camera system consists of a rear view camera, a display screen, and related control circuits. The camera is at the rear of the vehicle, and the display screen is in the center console. From the part layout position information, it is known that the battery is in the engine compartment and the body control module is below the driver's seat.

[0056] Based on this information, the vehicle wiring harness topology can be generated. For example, a wiring harness is led out from the battery to supply power to each system, there is a dedicated wiring harness connecting the temperature sensor and the air conditioning control module, and a wiring harness is led out from the camera at the rear of the vehicle to connect to the display screen in the center console, etc., forming a complete wiring harness connection architecture diagram. Figure 2 That is the schematic diagram of the overall topology of the wiring harness in an embodiment of the present application.

[0057] The embodiments of the present application can collect at least one of the vehicle equipment definition of the vehicle, the implementation solutions of each electrical system involved in the vehicle, and the relevant part layout position information to generate the vehicle wiring harness topology, so that the length and number of branches of the wiring harness can be roughly estimated based on the connection relationships and positions of each component, and then the cost of the wiring harness can be initially evaluated, providing a key direction for cost control in advance and avoiding cost out-of-control in the later stage.

[0058] Step S102, determine the segmented cost information of the corresponding wire harness application area according to the topology of the vehicle wire harness.

[0059] It can be understood that the wire harness application area here refers to the areas divided by different functions or positions in the vehicle. The vehicle wire harness will be distributed in these areas to achieve corresponding functions, such as the engine compartment, five doors + front and rear bumpers, cab and other areas. The wire harness in each area is responsible for connecting specific electrical equipment in that area.

[0060] The segmented cost information here refers to the wire loop cost data of different segments for the wire harness in each area after dividing the vehicle wire harness according to different application areas. It includes but is not limited to various cost-related information such as the material cost, manufacturing process cost, installation cost, etc. of the wire harness in that area.

[0061] In some embodiments, based on the topology of the vehicle wire harness, it is possible to clearly see the distribution of the wire harness in different areas and the connection relationship with the electrical components in each area. For different wire harness application areas, the length, specifications, complexity of the wire harness, and the electrical components it connects are different, and there are also differences in the temperature resistance level requirements, sealing level (water tightness, air tightness) requirements, outer protection material requirements, NVH requirements, etc. for the wire harness in different areas. These situations will all lead to differences in wire costs in different areas.

[0062] For example, the wire harness in the engine compartment may require special materials that are heat-resistant and oil-resistant, and need to connect multiple complex sensors and actuators. Its cost will be affected by these factors; while the wire harness in the door area may pay more attention to flexibility and waterproofness, and the cost factors are also different. By analyzing the characteristics and requirements of the wire harness in each area in the topology, combined with the price information of relevant materials and processes in the market, etc., the segmented cost information of each wire harness application area can be determined.

[0063] Taking an SUV vehicle as an example, the topology of its vehicle wire harness shows that the wire harness in the engine compartment area needs to connect various components such as sensors, fuel injectors, and starter motors of the engine. Due to the harsh environment, the wire harness is required to have high heat resistance and high protection performance. It uses heat-resistant insulating materials and special sheaths, and has a long length, a thick wire diameter, and many connection points. Based on these characteristics and market prices, it is estimated that the material cost of the wire harness in the engine compartment area is relatively high. Coupled with the complex manufacturing process and installation difficulty, it is determined that the segmented cost of the wire harness in this area is relatively high, assumed to be 800 yuan. The wire harness in the cab area mainly connects the instrument panel, seat adjustment motor, in-vehicle computer, etc., and has high requirements for the stability of signal transmission. More attention is paid to electromagnetic shielding performance in terms of materials, and the cost is relatively moderate, estimated to be 500 yuan. The wire harness in the door area needs to meet the flexibility requirements of frequent opening and closing of the door and has waterproof treatment, and the cost is relatively low, assumed to be 300 yuan, etc.

[0064] In the embodiments of the present application, when there is no wiring harness drawing and specific material information, the segmented cost information of different wiring harness application areas determined by the topological structure can be used to implement solutions for different vehicle function requirements, compare the cost changes of wiring harnesses in different areas of the topological structure under each solution, quickly determine which solution is more advantageous in cost control, make the cost estimation more targeted and reasonable, and avoid large errors caused by general estimation.

[0065] Optionally, in an embodiment of the present application, determining the segmented cost information of the corresponding wiring harness application area according to the vehicle wiring harness topological structure includes: identifying the attributes or categories of the wire circuits of each wiring harness; when the attributes or categories meet the preset estimation conditions, using the actual vehicle model as an index to query the first preset cost table to determine the segmented cost information of the corresponding wiring harness application area; when the attributes or categories do not meet the preset estimation conditions, determining that the wire circuit is a special circuit, and using the attributes or categories as an index to query the second preset cost table to generate the segmented cost information.

[0066] Those skilled in the art of this technology can understand that a wiring harness circuit refers to a complete circuit containing multiple parts designed to achieve specific electrical functions in a wiring harness system. During the wiring harness processing, each independent blanking of the wire constitutes a wiring harness circuit. The same functional signal can be composed of a single circuit or multiple circuits. Each time a solder joint or wire-to-wire connection occurs, a new circuit (but possibly the same signal) will be generated. The wiring harness circuit is used to provide power supply, grounding, bus signals, and the transmission path from sensors to controllers to actuators for each electrical system of the vehicle. As Figure 3 shown, Figure 3 This is the schematic diagram of the wiring harness circuit in an embodiment of the present application. The wire circuit of the wiring harness here refers to a closed circuit formed by one or more wires that can form a current path, which is the basic functional unit of the wiring harness.

[0067] The preset estimation conditions here refer to the criteria preset for determining whether a wire circuit is a conventional circuit and thus whether a conventional wiring harness cost estimation method can be used. It may involve thresholds or specific conditions of parameters such as current, voltage, signal type, wire diameter range, etc. Specifically, those skilled in the art can set them according to the actual situation. Here, only an exemplary illustration is given and no specific limitation is made.

[0068] The first preset cost table herein refers to a table that contains cost information of conventional wire loops in different application areas, indexed by the actual vehicle models of automobiles, and can quickly find the segmented costs of the application areas of conventional wire harnesses. The cost information can be, but is not limited to, formulated based on the empirical data of previous vehicle models and industry standards. The second preset cost table herein refers to a table specifically used to query the cost information of special loops. This table can be indexed by the attributes or categories of wire loops, and records the detailed cost data of different special loops. These data take into account factors such as special materials, processes, and technical requirements required for special loops.

[0069] In some embodiments, the present application first needs to identify the attributes or categories of each wire loop in the vehicle wire harness topology. If these attributes or categories meet certain estimation conditions, indicating that the wire harness loop is a conventional loop, the segmented cost information of the wire harness application area corresponding to the wire harness loop can be found in the first preset cost table.

[0070] When the attributes or categories of the wire loop (such as characteristics of the transmitted signal type, current-carrying capacity, voltage level, wire diameter, whether it is a high-voltage loop, whether special shielding is required, etc.) do not meet certain estimation conditions, it is determined as a special loop. At this time, it is necessary to query and generate segmented cost information in the second preset cost table according to its specific attributes or categories.

[0071] For example, the special loops in the present application include, but are not limited to, the following situations:

[0072] 1. The main power supply and grounding loops (in principle, loops with a wire diameter ≥ 8mm 2 are calculated separately, especially the power supply loops with a long layout path need to be separately concerned and counted, such as the main power supply loop after the battery is placed at the rear). They need to be separately counted according to material and labor costs, and filled in according to the template in Table 2. The copper wire quotation refers to the copper base: 62.29 yuan / kg;

[0073] 2. The cost of small assembly wire harnesses needs to be separately counted (labor costs, etc. have been considered comprehensively), and filled in according to the template in Table 2;

[0074] 3. The cost estimation of special material wires, such as panoramic image special material wires, LVDS special material wires, etc., can be estimated at 15 yuan per wire;

[0075] 4. The cost of battery terminals without the battery distribution box. If the battery distribution box is connected separately, an additional 30 yuan needs to be added, and the labor cost increases by 2 yuan.

[0076] It should be noted that in the embodiments of the present application, the changes in wire harness costs involved in various equipment configurations and implementation schemes of the vehicle include all the wire harness loop cost information involved, that is, it includes the loops statistically in each area + the costs of special loops (if any).

[0077] Suppose there is a wire loop connecting the battery and the motor in the vehicle harness topology of a new energy vehicle. After identification, the loop transmits high-voltage and high-current signals, and the current-carrying capacity exceeds the threshold in the preset estimation conditions, belonging to a special loop. Indexed by its attribute of "high-voltage and high-current transmission", it is found in the second preset cost table that due to the need to use special wires with good high-voltage insulation performance and thick wire diameters, as well as special high-voltage connectors and protection measures, etc., the segmented cost in the power system area where this loop is located is relatively high, assumed to be 2,000 yuan. For the wire loop connecting ordinary lights in the vehicle, which transmits low-voltage and low-current signals and meets the preset estimation conditions, indexed by the vehicle model in the first preset cost table, the segmented cost in the body lighting area where it is located is 200 yuan.

[0078] Embodiments of the present application can quickly determine the harness costs of each area of the vehicle based on the topology of the vehicle and the attributes and categories of the wire loops of the harness. For different implementation solutions of the vehicle's overall function requirements, the cost level can be quickly judged according to the attributes of the wire loops in the solution. For example, adding a high-power function module may generate a special loop, and by querying the cost table, the impact on the cost can be quickly known, making the cost estimation follow rules, avoiding blind estimation, and helping engineers focus on the high-cost factors of special loops and optimize them specifically in the design stage to reduce the overall harness cost.

[0079] Step S103, estimate the cost of the automotive harness including at least one of the processing cost, the loop material cost, and the cost sharing of the harness supplier based on the application area of the wire loop of each harness and the corresponding segmented cost information.

[0080] As a possible implementation method, embodiments of the present application can first clarify the specific harness application area where the wire loop of each harness is located, and then obtain the corresponding segmented cost information for this area. On this basis, considering the processing cost, the loop material cost, and the cost sharing of the harness supplier, combine at least one of these aspects of costs with the segmented cost information to comprehensively estimate the cost of the automotive harness, thereby obtaining a relatively accurate cost estimation value.

[0081] Among them, the processing cost here refers to the cost generated during the process of processing raw materials such as wires and connectors into finished harnesses that meet the requirements of automotive harnesses, including labor costs, equipment depreciation, energy consumption, processing technology costs, etc.

[0082] The loop material cost here refers to the costs of various materials that make up the wire loop, such as the procurement costs of the wire itself, connectors, insulating materials, protective sleeves, etc.

[0083] The cost sharing cost of the wire harness supplier here refers to the management cost, fuel cost, enterprise profit, sales cost, financial cost, packaging and transportation cost and other costs in the process of the wire harness supplier producing and supplying wire harnesses. In addition to the direct material and processing costs, these costs need to be evenly distributed to each wire harness product to form the cost sharing cost of the wire harness supplier.

[0084] For example, assuming that the segmented cost information of the door wire harness application area of a car is 500 yuan through topological structure analysis, of which the wire loop material cost is about 300 yuan. The processing technology of this door wire harness is relatively complex, and the processing cost is estimated to be 150 yuan. The cost evenly distributed to this door wire harness by the wire harness supplier according to its own operating costs and profit targets is 50 yuan. Then based on this cost information, the total cost of this door wire harness is estimated to be 500 + 150 + 50 = 700 yuan.

[0085] The embodiment of the present application can quickly outline a general cost framework by combining the segmented costs of the wire harness application area with relevant cost factors, provide a key reference for project budgeting, and avoid budget overruns or waste of funds caused by unclear costs. And this estimation method can make the cost evaluation more detailed and comprehensive, covering multiple cost dimensions, and helps to discover the key points of cost control in advance. For example, if the processing cost in a certain area is too high, measures such as optimizing the process or replacing the supplier can be considered in advance to reduce costs.

[0086] Optionally, in an embodiment of the present application, based on the wire harness application area where the wire loop of each wire harness is located and the corresponding segmented cost information, estimating the cost of the automotive wire harness including at least one of the processing cost, the loop material cost, and the cost sharing cost of the wire harness supplier, includes: inputting the wire harness application area where the wire loop of each wire harness is located and the corresponding segmented cost information into a pre-constructed wire harness cost calculation model to output the cost of the automotive wire harness, where the wire harness cost calculation model is trained by the historical costs and design schemes of the wire harnesses of the same platform models of the vehicle.

[0087] It can be understood that the pre-established wire harness cost calculation model here refers to a mathematical model pre-constructed based on the historical costs and design schemes of the wire harnesses of the same platform models of the vehicle, which can be used to calculate the wire harness cost of the current model.

[0088] In some embodiments, the present application can input the specific location where the wire loop of each wire harness is located and the cost information of the corresponding part into the pre-established wire harness cost calculation model. The model will analyze, process and calculate the input information based on the existing historical cost data and design scheme experience of the wire harnesses of the same platform models, so as to obtain the cost of the automotive wire harness.

[0089] For example, assume that there is a previous model among the models of the same platform of a certain automobile, and the historical cost data of the engine compartment wiring harness is complete, and the design scheme is also recorded. There is a wire loop in the engine compartment of the new model, which connects from the battery to the starting motor of the engine. This wire loop is in the wiring harness application area of the engine compartment. According to past experience, this wire loop can be divided into two segments according to factors such as length and wire diameter. The cost of one segment connecting the battery is calculated to be 5 yuan, and the cost of the other segment connecting the starting motor is 8 yuan. Inputting this information into the wiring harness cost calculation model, the model combines the relevant data of the models of the same platform, and considering factors such as possible design changes in the new model, finally calculates that the cost of the wiring harness where this wire loop in the engine compartment is located may be 20 yuan.

[0090] In the embodiment of the present application, when the vehicle wiring harness drawing is not developed in the early stage and specific material information is lacking, the historical data of the models of the same platform and the pre-established wiring harness cost calculation model can be used to roughly estimate the possible wiring harness cost. When analyzing the implementation scheme of the vehicle's overall function requirements, it can also quickly give a reference value of the wiring harness cost, helping decision-makers evaluate the cost feasibility in advance, providing a basis for the optimization and adjustment of the scheme, and avoiding situations such as design changes caused by cost problems in the later stage.

[0091] Optionally, in an embodiment of the present application, it further includes: generating a wiring harness optimization suggestion for the automobile according to the topology structure of the vehicle wiring harness based on the cost of the automobile wiring harness, where the wiring harness optimization suggestion includes at least one of a modular design suggestion, a wiring harness length suggestion, a standardized part selection suggestion, a procurement suggestion, and a protocol suggestion; pushing the wiring harness optimization suggestion to a preset user.

[0092] In some other embodiments, after obtaining the cost of the vehicle wiring harness, the present application can also generate a wiring harness optimization suggestion for the automobile according to the topology structure of the vehicle wiring harness, including but not limited to at least one of a modular design suggestion, a wiring harness length suggestion, a standardized part selection suggestion, a procurement suggestion, and a protocol suggestion.

[0093] Then, the embodiment of the present application can push these wiring harness optimization suggestions to a preset user, so that the preset user can optimize the wiring harness or vehicle design according to the estimated wiring harness cost. Here, the preset user can be understood as the staff whose work is somewhat related to the wiring harness cost in the initial stage of the vehicle project.

[0094] Specifically, the embodiments of the present application can analyze the problems and optimization space existing in the existing structure and cost composition based on the known cost data of automotive wire harnesses, combined with the electrical connection relationships and layout information presented by the vehicle wire harness topology. For example, by analyzing the topology, it is found that the connection between certain modules is too complex, resulting in an overly long wire harness and increased costs. In this case, modular design suggestions can be put forward to optimize the module division; reasonable wire harness length suggestions can be given according to the actual distance and electrical requirements between each node; from the perspective of cost reduction and improved versatility, standardized part selection suggestions can be proposed based on the part types and usage frequencies involved in the topology; considering factors such as cost and market supply comprehensively, procurement suggestions and agreement suggestions can be formulated to achieve goals such as cost control and risk avoidance.

[0095] Among them, the modular design suggestion can be understood here as the design ideas and related suggestions that are convenient for design, production, installation, and maintenance and are pushed to certain customers after dividing the automotive wire harness into different modules with relatively independent functions and structures according to factors such as function or region.

[0096] The wire harness length suggestion can be understood here as the reasonable value range or optimization plan proposed for the length of each section of the wire harness according to the layout and topology of the vehicle's electrical equipment, which helps to reduce the wire harness length to lower costs and weight while ensuring electrical performance.

[0097] The standardized part selection suggestion can be understood here as recommending to certain customers to use general parts that meet industry standards or enterprise standards, such as connectors, terminals, etc., in the design and production of automotive wire harnesses to improve versatility, reduce costs, and improve production efficiency.

[0098] The procurement suggestion can be understood here as the guiding opinions put forward for the procurement of automotive wire harness-related raw materials and components based on factors such as wire harness cost, quality, and suppliers, such as procurement quantity, procurement timing, and supplier selection.

[0099] The agreement suggestion can be understood here as the optimization suggestions for the agreement terms regarding wire harness procurement, cooperation, etc. with suppliers or partners, such as quality standards, delivery dates, payment methods, etc.

[0100] The optimization suggestions generated by the embodiments of the present application based on wire harness cost and topology can provide directions and bases for quickly evaluating wire harness costs and help predict the cost change trends under different optimization plans in advance. When analyzing the implementation solutions for vehicle functions, these suggestions help to evaluate the feasibility of the solutions from the cost perspective and effectively control wire harness costs by optimizing design and procurement, etc., improving the cost performance and market competitiveness of the vehicle.

[0101] The following uses a specific example to explain the present application in detail.

[0102] Figure 4 Flow chart of rapid cost estimation based on wire harness circuit for an embodiment of the present application, as Figure 4 shown below:

[0103] Step S401, analysis starts;

[0109] Step S407, identify the signal circuits involved according to the function implementation solutions and layout information of the electrical systems;

[0110] Step S408, identify the wire circuits information involved in different segmented wire harnesses according to the wire harness topology and the signal circuits involved;

[0111] Step S409, determine whether special circuits are involved:

[0112] Step S410, if there are special circuits, perform cost estimation according to "Table 2 Rapid Cost Estimation Table for Special Wire Harness Circuits";

[0113] Step S411, for the circuits not involved, calculate the circuit costs involved in different segmented wire harnesses according to "Table 1 Rapid Cost Estimation Table for Wire Harness Segmented Circuits", compare with the average circuit cost, and take the minimum value for estimation;

[0114] Step S412, sum up the costs of all circuit wire harnesses as the estimation result of the changes in wire harness costs involved in various equipment configurations and implementation solutions of the vehicle.

[0115] Step S413, end the process.

[0116] For example, different wire harness application areas and their segmented cost information are defined as follows:

[0117] The engine compartment area includes: front wire harness, powertrain wire harness, and small wire harnesses arranged in this area. For pure electric and fuel models, the single circuit cost is estimated at 2.8 yuan;

[0118] The estimated cost for the five-door + front and rear bumper area includes: the front door wiring harness, the rear door wiring harness, the tailgate wiring harness, the front and rear bumper wiring harnesses, and the small wiring harnesses arranged in this area. The front door wiring harness is estimated at 2.0 yuan per single circuit cost, and the remaining wiring harnesses are estimated at 2.3 yuan per single circuit cost;

[0119] The cab area includes: the body wiring harness, the instrument panel wiring harness, the roof wiring harness, the sub-instrument panel wiring harness, and the small wiring harnesses arranged in this area. For pure electric and fuel models, it is estimated at 2.0 yuan per single circuit cost. For PHEV or REEV models (considering the battery rear-mounted condition), the body wiring harness is estimated at 2.5 yuan per single circuit cost, and the remaining wiring harnesses are estimated at 2.0 yuan per single circuit cost.

[0120] For PHEV or REEV models (considering the battery rear-mounted condition), the front wiring harness is estimated at 3.2 yuan per single circuit cost, and the remaining wiring harnesses are estimated at 2.8 yuan per single circuit cost;

[0121] For pure electric and fuel models, the average unit price of all wiring harness circuits in the vehicle is estimated at 2.35 yuan;

[0122] Then, according to the wiring harness topology and the signal circuits involved, identify the wire circuit information involved in different segmented wiring harnesses; judge whether special circuits are involved: if there are special circuits, estimate the cost according to the "Table 2 Quick Estimation Table of Special Wiring Harness Circuit Costs"; for circuits not involved, calculate the circuit costs involved in different segmented wiring harnesses according to the "Table 1 Quick Estimation Table of Wiring Harness Segmented Circuit Costs", and compare with the average circuit cost, and take the minimum value for estimation. Finally, sum up the costs of all circuit wiring harnesses as the estimation result of the change in the wiring harness cost involved in various equipment configurations and implementation plan changes of the vehicle.

[0123] (1) Taking the example of adding an electric tailgate function, the system includes an electric tailgate controller, a trunk lock, a trunk close switch, and a tailgate strut motor. The number of circuit loops for each segmented wiring harness is counted as follows:

[0124] Table 1

[0125]

[0126]

[0127] Based on the circuit costs involved in different segmented wiring harnesses, compare with the average circuit cost, and take the minimum value of 68.7 yuan for estimation.

[0128] (2) Taking the radio frequency transceiver as an example, the system only includes a radio frequency transceiver controller. The number of circuit loops for each segmented wiring harness is counted as follows:

[0129] Table 2

[0130]

[0131]

[0132] Based on the circuit costs involved in different segmented wire harnesses, compare with the average circuit cost, and estimate by taking the minimum value of 8 yuan.

[0133] (3) Taking the IBC function as an example, the system includes an IBC controller, a brake fluid level sensor, left and right front wheel speed sensors, left and right rear wheel speed sensors, and caliper motors. The statistics of the number of circuit segments for each wire harness are as follows (excluding special circuits, and the costs of special circuits are calculated separately):

[0134] Table 3

[0135]

[0136] Based on the circuit costs involved in different segmented wire harnesses, compare with the average circuit cost, estimate by taking the minimum value of 108.1 yuan, and then combine the cost of the special circuit, which is 90 yuan in total. The overall cost of the circuit wire harness is 198.1 yuan.

[0137] It should be noted that the embodiments of the present application are for the design requirements of each region of the vehicle wire harness, and the number of circuits and unit prices in the region are estimated as a whole. The more regions and circuits are covered, the closer the calculation result will be to the true value. Based on this method, the vehicle wire harness costs of three historical models are backtested, and the overall cost deviation is within 3%. If the materials of specific circuits are known, the cost can be accurately calculated.

[0138] According to the method for estimating the cost of an automotive wire harness proposed in the embodiments of the present application, based on the topology structure of the vehicle wire harness, the segmented cost information and circuit composition of different wire harness application regions can be determined, and the cost change of the wire harness can be quickly estimated. Thus, at the project planning and product definition stages, the evaluation and analysis of the wire harness cost can be effectively and quickly carried out according to the implementation plan of the vehicle function requirements, improving the efficiency of evaluating the wire harness cost. Combining the cost data information of historical models on the same platform in the past, more accurate wire harness cost calculations can be performed, and thus a design cost basis can be provided for the development concept of the vehicle electrical solution. Thus, it solves the problems in the related technologies that the method for estimating the cost of vehicle wire harnesses cannot quickly, efficiently and reasonably analyze and estimate the wire harness cost according to the implementation plan of vehicle function requirements at the stages where wire harness drawings have not been developed and specific material information of the wire harness composition has not been given, and it is difficult to meet the requirements for analyzing and estimating the wire harness cost in the initial stage of the project.

[0139] Next, an apparatus for estimating the cost of an automotive wire harness according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0142] Among them, the acquisition module 100 is used to acquire the topology structure of the vehicle's entire vehicle wiring harness during the vehicle project planning stage or the vehicle product definition stage.

[0143] The determination module 200 is used to determine the segmented cost information of the corresponding wiring harness application area according to the topology structure of the entire vehicle wiring harness.

[0144] The estimation module 300 is used to estimate the cost of the automotive wiring harness including at least one of the processing cost, the loop material cost, and the cost sharing of the wiring harness supplier based on the wiring harness application area where each wire loop of the wiring harness is located and the corresponding segmented cost information.

[0148] The first generation unit is used to determine that the wire loop is a special loop when the attributes or categories do not meet the preset estimation conditions, and query the second preset cost table with the attributes or categories as the index to generate the segmented cost information.

[0149] Optionally, in an embodiment of the present application, the acquisition module includes: a collection unit and a second generation unit.

[0150] Among them, the collection unit is used to collect at least one of the vehicle's entire vehicle equipment definition, the implementation solutions of each electrical system involved in the vehicle, and the information on the layout positions of related parts.

[0151] The second generation unit is used to generate the topology structure of the entire vehicle wiring harness based on at least one of them.

[0152] Optionally, in an embodiment of the present application, it further includes: a generation module and a push module.

[0156] It should be noted that the foregoing explanation of the embodiments of the method for estimating the vehicle wiring harness cost also applies to the device for estimating the vehicle wiring harness cost in this embodiment, and will not be repeated here.

[0157] According to the device for estimating the vehicle wiring harness cost proposed in the embodiments of the present application, based on the vehicle wiring harness topology structure of the vehicle, the segment cost information and loop composition of different wiring harness application areas can be determined, and the cost change of the wiring harness can be quickly estimated. Thus, in the project planning and product definition stages, the evaluation and analysis of the wiring harness cost can be effectively and quickly carried out according to the implementation scheme of the vehicle function requirements, improving the evaluation efficiency of the wiring harness cost. Combining with the cost data information composition of the previous historical models of the same platform, more accurate wiring harness cost calculation can be performed, and thus a design cost basis can be provided for the development concept of the vehicle electrical scheme. Thus, it solves the problems in the related technologies that the method for estimating the vehicle wiring harness cost cannot quickly, efficiently and reasonably analyze and estimate the wiring harness cost according to the implementation scheme of the vehicle function requirements in the stages where the wiring harness drawings have not been developed and the specific material information of the wiring harness composition has not been given, such as in the project planning and product definition stages, and it is difficult to meet the analysis and estimation requirements of the wiring harness cost in the initial stage of the project.
