For example, the cab and body, as core components of a car, account for 20%-30% of the total vehicle cost. However, existing cost control methods are mostly focused on a single aspect, such as material replacement or process simplification, which leads to a difficulty in balancing end-to-end cost control and performance assurance in current technologies. Summary of the Invention

[0004] This invention provides a method for cost control of vehicles. The method includes: acquiring bill of materials (BOM) information of a target vehicle model and vehicle components to be analyzed for the target vehicle model; filtering target materials associated with the vehicle components to be analyzed from the BOM information; acquiring preset reference indicators for each target material; scoring the material according to preset analysis dimensions and preset reference indicators to obtain a scoring result for the material; wherein the preset analysis dimensions are related to the performance, quality, and cost of the material; and determining the cost control result corresponding to the material based on the scoring result.
[0005] Furthermore, if the material belongs to the parts category, the preset analysis dimensions include: functional and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, and cost evaluation items; among them, the four-fold evaluation items include: platformization sub-evaluation items, modularization sub-evaluation items, generalization sub-evaluation items, and standardization sub-evaluation items; the cost evaluation items include: raw material cost sub-evaluation items, production cost sub-evaluation items, logistics cost sub-evaluation items, and service cost sub-evaluation items.

[0008] Furthermore, the step of determining the cost control result corresponding to the material based on the scoring result includes: if the scoring result is greater than or equal to a preset scoring threshold, the current cost of the material is determined as the final cost of the material.
[0009] Furthermore, the steps for determining the cost control result corresponding to the material based on the scoring results include: if the scoring result is less than the preset scoring threshold, optimizing the current cost of the material according to the preset optimization method to obtain a new current cost; repeatedly executing the steps of obtaining the preset reference indicators corresponding to the material, scoring the material according to the preset analysis dimensions and preset reference indicators, until the scoring result is greater than or equal to the preset scoring threshold, and determining the last obtained new current cost as the final cost of the material.
[0010] Furthermore, the vehicle components to be analyzed are: body, engine assembly, chassis, or electrical equipment.

Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

Detailed Implementation
[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Cost control methods in related technologies are mostly focused on a single stage, and mainly have the following problems: 1. Failure to consider the relationship between cost and performance during the design phase can easily lead to "sacrificing performance to reduce costs" or "over-investing to maintain performance"; 2. Material selection relies on experience and lacks quantifiable cost-performance evaluation standards, which can easily lead to material waste. 3. Lack of dynamic early warning in supply chain management means that fluctuations in raw material prices or supplier delivery delays can lead to unexpected cost increases. 4. Without a closed-loop verification mechanism throughout the entire process, the effectiveness of cost control cannot be iterated and optimized in real time.
[0019] Based on this, embodiments of the present invention provide a method, apparatus, and electronic device for controlling vehicle costs, which can be applied to applications that require cost control of vehicles.
[0020] To facilitate understanding of this embodiment, a vehicle cost control method disclosed in this embodiment of the invention will first be introduced, such as... Figure 1 As shown, the method includes the following steps: Step S102: Obtain the bill of materials information for the target vehicle model, as well as the vehicle components to be analyzed for the target vehicle model; If classified by vehicle structure, the target vehicle models mentioned above can include: single-box, two-box, and three-box vehicles; if classified by function and purpose, the target vehicle models mentioned above can include: sedans, SUVs, new energy vehicles, etc.; the specific classification of vehicle models can be based on different classification criteria, which are not limited here; the vehicle components to be analyzed mentioned above can be: body, engine assembly, chassis, or electrical equipment, etc.; in actual implementation, after determining the target vehicle model to be analyzed, the bill of materials (BOM) information of the target vehicle model and the corresponding vehicle components to be analyzed can be obtained; for example, taking the target vehicle model as the classic version and the vehicle component to be analyzed as the body, the purchasing department can conduct in-depth research at the supplier to obtain the BOM (Bill of Materials) table corresponding to the classic version model, that is, the bill of materials information.
[0021] Step S104: Filter out the target materials associated with the vehicle parts to be analyzed from the bill of materials information; In practice, since the bill of materials information usually contains materials corresponding to the whole vehicle, some materials are not related to the vehicle parts to be analyzed. Therefore, we can first filter out the target materials related to the vehicle parts to be analyzed from the bill of materials information to facilitate subsequent analysis.
[0022] Step S106: For each material in the target materials, obtain the corresponding preset reference index. Based on the preset analysis dimensions and preset reference index, score the material to obtain the corresponding score result. The preset analysis dimensions are related to the performance, quality and cost of the material. The aforementioned preset reference indicators can be understood as pre-defined performance, quality, and cost indicators that the material must meet. The number of preset analysis dimensions is usually multiple, and can be set according to actual needs. These preset analysis dimensions are typically related to the material's performance, quality, and cost; for example, they may include functional and performance evaluation items, quality evaluation items, and cost evaluation items. In actual implementation, the target material usually includes multiple materials. Preset reference indicators corresponding to each material can be obtained. Then, for each material, a score is calculated based on the preset analysis dimensions and the corresponding preset reference indicators, yielding a corresponding score result. Generally, the more the material's performance, quality, and cost conform to the preset reference indicators, the higher the score result; conversely, the lower the score result, the less conformity.
[0023] Step S108: Determine the cost control result corresponding to the material based on the scoring results.
[0024] In practice, the cost control result can be determined based on the scoring result of each material. This cost control result can be understood as the final cost of the material.
[0025] The aforementioned cost control method for vehicles involves obtaining the bill of materials (BOM) information for the target vehicle model and the vehicle components to be analyzed. Target materials associated with these components are then selected from the BOM information. For each target material, a pre-defined reference index is obtained. Based on pre-defined analysis dimensions and the pre-defined reference index, the material is scored to obtain a score result. The pre-defined analysis dimensions are related to the material's performance, quality, and cost. Based on the score result, the corresponding cost control result is determined. This method can score each material associated with the vehicle components to be analyzed according to pre-defined analysis dimensions and pre-defined reference indexes, and determine the cost control result based on the score result. Because the pre-defined analysis dimensions are related to the material's performance, quality, and cost, the obtained cost control result can effectively balance end-to-end product cost and performance.
[0026] This invention also provides another method for controlling vehicle costs, which is implemented based on the method described in the above embodiments. This method includes the following steps: Step 1: Obtain the bill of materials information for the target vehicle model, as well as the vehicle components to be analyzed for the target vehicle model; Step 2: Filter out the target materials associated with the vehicle parts to be analyzed from the bill of materials information; Step 3: For each material in the target materials, obtain the corresponding preset reference index. Based on the preset analysis dimensions and preset reference index, score the material to obtain the corresponding score result. Among them, the preset analysis dimensions are related to the performance, quality and cost of the material. If the material belongs to the parts category, the preset analysis dimensions include: functional and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, and cost evaluation items; among them, the four-fold evaluation items include: platformization sub-evaluation items, modularization sub-evaluation items, generalization sub-evaluation items, and standardization sub-evaluation items; the cost evaluation items include: raw material cost sub-evaluation items, production cost sub-evaluation items, logistics cost sub-evaluation items, and service cost sub-evaluation items.
[0027] The above-mentioned part categories can be understood as the categories corresponding to the smallest indivisible manufacturing unit in mechanical manufacturing. For example, bolts and washers are both part categories. The above-mentioned functional and performance evaluation items can be used to indicate whether the function and performance of the material meet the preset reference indicators. The above-mentioned quality evaluation items can be used to indicate whether the quality of the material meets the preset reference indicators. The above-mentioned platformization sub-evaluation items can be used to indicate the possibility of using the material to construct a platform to generate products that meet the needs of different customers. The above-mentioned modularization sub-evaluation items can be used to indicate the possibility of using the material as an independent standard module and connecting it to external systems through a standard interface. The above-mentioned generalization sub-evaluation items can be used to indicate the possibility of using the material as a... The possibility of using general-purpose materials; the standardization sub-evaluation item mentioned above can be used to indicate: assess the possibility of developing, publishing, and implementing uniform standards for the material for use as a standard part; the raw material cost sub-evaluation item mentioned above can be used to indicate: assess the degree of matching between the raw material cost of the material and the industry average cost in the preset reference indicators; the production cost sub-evaluation item mentioned above can be used to indicate: assess whether the production cost of the material is already the optimal cost; the logistics cost sub-evaluation item mentioned above can be used to indicate: assess whether the logistics cost of the material is already the optimal cost; the service cost sub-evaluation item mentioned above can be used to indicate: assess whether the service cost of the material is already the optimal cost; the normalization evaluation item mentioned above is used to indicate whether the material is allowed to be used in other vehicle parts besides the vehicle parts to be analyzed.
[0028] In actual implementation, if the material belongs to the parts category, the cost baseline conditions can be set as follows: analyze the material through the five dimensions of the above-mentioned function and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, and cost evaluation items. For example, a cost baseline assessment can be performed as follows: 1. For the function and performance evaluation items, if the material meets the basic functions and performance, you can fill in a score of 1; if it does not meet the requirements, you can fill in a score of 0. For the quality evaluation items, if the material meets the quality indicators, you can fill in a score of 1; if it does not meet the requirements, you can fill in a score of 0. For the four-fold evaluation items, if the material meets the four-fold principles, you can fill in a score of 1; if it does not meet the requirements, you can fill in a score of 0. For evaluation items that cannot be determined, you can fill in a score of 0.
[0029] To facilitate understanding, the principles of the Four Modernizations will be further explained below: A. Platformization A platform is constructed using parts / assemblies / systems with the same characteristics (i.e., common components), which can simultaneously support the development of different vehicle models. Customized features are added to the platform to create products that meet the needs of different external customers.
[0030] B. Generalization Standardization is a form of applicability that maximizes the scope of use of the same object (part / assembly / system) based on interchangeability.
[0031] C. Modularization Based on the platform definition, relatively independent modules are divided and designed (a module is a set of parts / components / assemblies that implement specific functions and performance and have standardized interfaces). Different platforms are formed by selecting and combining modules and the standard interfaces between modules.
[0032] D. Standardization For repetitive things and concepts, standardization is achieved through the development, publication, and implementation of standards to obtain optimal order.
[0033] 2. For the normalization evaluation item, if the material is allowed to be used in other vehicle parts besides the vehicle part being analyzed, the normalization attribute is preferred, and you can enter a score of +1; if the material is restricted to be used in some other vehicle parts besides the vehicle part being analyzed, the normalization attribute is restricted, and you can enter a score of 0; if the material is prohibited from being used in other vehicle parts besides the vehicle part being analyzed, the normalization attribute is prohibited, and you can enter a score of -1. 3. For the cost assessment item, if the end-to-end cost of the vehicle component to be analyzed is in line with or lower than the industry average, you can fill in a score of 1; if it is higher than the industry average, you can fill in a score of 0.
[0034] The aforementioned cost assessment items can specifically be end-to-end costs. For ease of understanding, the following provides further explanation of end-to-end costs: A. Raw material costs Assess whether the unit price of raw materials, the amount of raw materials consumed, the material utilization rate, and the price of outsourced parts are reasonable, and explore whether there is room for cost reduction.
[0035] B. Production Costs Assess whether the processing cost is reasonable, whether the mold cost and dimensions are reasonable, the amortization progress of the mold cost (the quantity already supplied), etc., and explore whether there is room for cost reduction.
[0036] C. Logistics costs Assess whether logistics costs are reasonable and explore whether there is room for cost reduction.
[0037] D. Service Costs By assessing a supplier's parts return, scrap, and claims history, users can assist suppliers in making improvements and reducing service costs.
[0038] If the material belongs to the component category, the preset analysis dimensions also include: product lifecycle design assessment items; product lifecycle design assessment items include: procureability assessment items, manufacturability assessment items, maintainability assessment items, and serviceability assessment items.
[0039] The aforementioned component categories can be understood as independent assembly units with specific functions, composed of multiple parts; the aforementioned product lifecycle design evaluation items can be represented by DFX (Design for X, where X represents a stage or characteristic of the product lifecycle); the aforementioned procureability sub-evaluation item can be used to indicate whether the material can be easily and economically obtained; the aforementioned manufacturability sub-evaluation item can be used to indicate whether the material can be easily and efficiently manufactured; the aforementioned maintainability sub-evaluation item can be used to indicate whether the material can be easily and quickly repaired in the event of a failure; the aforementioned serviceability sub-evaluation item can be used to indicate whether the material can be easily and quickly serviced and maintained during use.
[0040] In actual implementation, if the material belongs to the component category, the cost baseline conditions can be set as follows: analyze the material through the six dimensions mentioned above: functional and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, product life cycle design evaluation items, and cost evaluation items. For example, the cost baseline requirements could be: basic functions and performance must be met, quality objectives, standardization, normalization, and DFX principles must be followed, and the end-to-end cost structure must be reasonable; the cost baseline evaluation could be as follows: 1. For the scoring of functional and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, and cost evaluation items, please refer to the relevant descriptions above, which will not be repeated here.
[0041] 2. For product lifecycle design assessment items, such as DFX, if the material meets the relevant assessment indicators, you can fill in a score of 1; if it does not meet the indicators, you can fill in a score of 0.
[0042] Step 4: If the scoring result is greater than or equal to the preset scoring threshold, the current cost of the material is determined as the final cost of the material. Step 5: If the score result is less than the preset score threshold, optimize the current cost of the material according to the preset optimization method to obtain a new current cost; Step 6: Repeat the steps of obtaining the preset reference indicators corresponding to the material, scoring the material according to the preset analysis dimensions and preset reference indicators, until the scoring result is greater than or equal to the preset scoring threshold, and determine the new current cost obtained at the last time as the final cost of the material.
[0043] The aforementioned preset scoring threshold can be set according to actual needs. For example, the corresponding preset scoring threshold can be set to 8 points. That is, if the scoring result is ≥8 points, the material meets the cost baseline requirements, and the current cost of the material can be determined as the final cost of the material. If the scoring result is <8 points, the material does not meet the cost baseline requirements. In this case, cost optimization needs to be carried out according to the preset optimization method. The preset optimization method can be set according to actual needs. For example, parts replacement can be performed. After obtaining the new current cost, the above scoring process can be repeated until the scoring result is greater than or equal to the preset scoring threshold. At this time, the new current cost obtained at the last time can be determined as the final cost of the material. After determining the final cost, the cost design method for the vehicle component to be analyzed can be solidified.
[0044] In actual implementation, at least one first scoring threshold can be set according to actual needs. Each first scoring threshold is usually greater than the above-mentioned preset scoring threshold. For example, if the preset scoring threshold is 8 points and the first scoring threshold is 11 points, if 8 points < the scoring result < 11 points, it can be considered that the cost baseline requirement is "met". If 11 points < the scoring result, it can be considered that the cost baseline requirement is "very met".
[0045] For ease of understanding, two implementation examples are provided below: Example 1 Table 1 shows a bill of materials, which displays the materials, quantity, weight, and original cost of the A-pillar upper guard plate. Table 2 shows a rating table, which displays the ratings for each evaluation item of the A-pillar upper guard plate across five dimensions.
[0046] Table 1
[0047] Table 2
[0048] 1. Basic Functions / Performance: The A-pillar upper guard plate meets the basic functions and performance requirements of the interior, scoring 1 point; 2. Quality Trade-offs / 12MIS: The A-pillar upper guard plate is of stable quality and meets the quality requirements, with a score of 1; 3. Four principles: The A-pillar upper guard plate is an interior trim component. Due to styling factors, it cannot achieve platformization, modularization, and universalization. However, the design method and interface structure meet the standardization requirements, so the scores are 0, 0, 0, and 1 respectively. 4. Normalization: The normalization attribute of the A-pillar upper guard plate is preferred, with a score of 1; 5. End-to-end cost: The purchase price of the A-pillar upper guard plate is 22 yuan / Kg, which is the industry average, and the score is 1; the production cost, logistics cost and service cost cannot be confirmed as optimal, and on-site end-to-end analysis is required, so the score is 0. 6. Total score: The baseline evaluation score of the A-pillar upper guard plate is 5 points. If it is less than 7 points, it does not meet the baseline requirements and cost optimization is required.
[0049] Based on the supplier's cost sheet, production costs, logistics costs, and service costs can be analyzed, cost targets can be set, cost structure can be optimized, and a cost baseline can be established to determine the final cost.
[0050] Example 2 Table 3 shows a bill of materials that displays the quantity, weight, and original cost of the driver's seat assembly. Table 4 shows a rating table that displays the ratings for each evaluation item of the driver's seat assembly across six dimensions.
[0051] Table 3
[0052] Table 4
[0053] 1. Basic Functions / Performance: The driver's seat assembly meets the basic functions and performance requirements, and scores 1. 2. Quality Trade-offs / 12MIS: Driver's seat assembly. If the 12MIS score exceeds 5, there are many quality issues, and the score is 0. 3. The principle of four-fold standardization: The driver's seat assembly cannot achieve platformization, modularization, and universalization due to styling factors, but the design method and interface structure meet the standardization requirements, so the score is 0 0 0 1; 4. Normalization: The driver's seat assembly normalization attribute, based on function, performance, and vehicle configuration selection, is defined as limited selection and scores 0. 5. DFX: Procurementability and manufacturability meet development requirements, score 1 point; Maintainability and serviceability cannot be determined to be optimal, further analysis with suppliers and service departments is required, score 0. 6. End-to-end cost: The purchase price of the driver's seat assembly is 1,800 yuan / kg, which is the industry average, and the score is 1; the production cost, logistics cost, and service cost cannot be confirmed as optimal, and on-site end-to-end analysis is required, so the score is 0. 7. Total Score: The baseline evaluation score for the driver's seat assembly is 5 points. If the score is less than 7 points, the baseline requirements are not met, and cost optimization is required.
[0054] Based on the supplier's cost sheet, we can analyze DFX, production costs, logistics costs, and service costs, set cost targets, optimize cost structure, and establish cost baselines to determine the final cost.
[0055] This solution involves scanning each component in the cost BOM of the vehicle parts to be analyzed. It can focus on scanning higher-cost components for further breakdown, while also applying the same method to lower-cost smaller components to analyze their cost composition and gradually improve the cost baseline.
[0056] The solution establishes a comprehensive scoring mechanism, which scores based on basic functions, basic performance, quality trade-offs, the four principles, the normalization principle, and the end-to-end cost principle. It establishes an effective evaluation mechanism, improves target costs, determines cost baselines, and realizes the accumulation and application of cost control methods.
[0057] The aforementioned cost control method for vehicles is a cab body cost control method that covers the entire process of "design-materials-process-supply chain" and can balance cost and performance. It can be applied to the production scenarios of commercial vehicles and economy passenger vehicles that are highly sensitive to cost. This method establishes a cost-performance correlation model to achieve full-process cost control from four dimensions: design, materials, process and supply chain. It makes up for the shortcomings of cost-forward design and effectively reduces manufacturing costs. It solves the problem of difficulty in balancing end-to-end cost control and performance assurance in existing technologies. It can be applied to the mass production of vehicle components to be analyzed in various commercial vehicles and passenger vehicles.
[0058] This invention provides a vehicle cost control device, such as... Figure 2As shown, the device includes: an acquisition module 20, used to acquire the bill of materials information of the target vehicle model and the vehicle parts to be analyzed of the target vehicle model; a filtering module 21, used to filter out the target materials associated with the vehicle parts to be analyzed from the bill of materials information; a scoring module 22, used to acquire the preset reference index corresponding to each material in the target materials, and score the material according to the preset analysis dimensions and the preset reference index to obtain the scoring result corresponding to the material; wherein, the preset analysis dimensions are related to the performance, quality and cost of the material; and a determination module 23, used to determine the cost control result corresponding to the material based on the scoring result.
[0059] The aforementioned cost control device for vehicles can score each material associated with the vehicle components to be analyzed according to preset analysis dimensions and preset reference indicators, and determine the cost control result based on the scoring results. Since the preset analysis dimensions are related to the performance, quality, and cost of the material, the obtained cost control result can better balance the end-to-end cost and performance of the product.
[0060] Furthermore, if the material belongs to the parts category, the preset analysis dimensions include: functional and performance evaluation items, quality evaluation items, four-fold evaluation items, normalization evaluation items, and cost evaluation items; among them, the four-fold evaluation items include: platformization sub-evaluation items, modularization sub-evaluation items, generalization sub-evaluation items, and standardization sub-evaluation items; the cost evaluation items include: raw material cost sub-evaluation items, production cost sub-evaluation items, logistics cost sub-evaluation items, and service cost sub-evaluation items.
[0061] Furthermore, the normalized evaluation item is used to indicate whether the material is permitted for use in vehicle components other than those being analyzed.
[0062] Furthermore, if the material belongs to the component category, the preset analysis dimensions also include: product lifecycle design assessment items; product lifecycle design assessment items include: procureability assessment items, manufacturability assessment items, maintainability assessment items, and serviceability assessment items.
[0063] Furthermore, the determination module is also used to: if the scoring result is greater than or equal to a preset scoring threshold, determine the current cost of the material as the final cost of the material.
[0064] Furthermore, the determination module is also used to: if the scoring result is less than the preset scoring threshold, optimize the current cost of the material according to the preset optimization method to obtain a new current cost; repeatedly execute the steps of obtaining the preset reference index corresponding to the material, and scoring the material according to the preset analysis dimension and the preset reference index, until the scoring result is greater than or equal to the preset scoring threshold, and determine the last obtained new current cost as the final cost of the material.
[0065] Furthermore, the vehicle components to be analyzed are: body, engine assembly, chassis, or electrical equipment.
