Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automobile design, and in particular to a method for evaluating automobile perceived quality. Background Art
[0002] Automotive perceived quality (PQ) influences user evaluation of a product through a multi-sensory experience. This involves the user's subjective experience of the vehicle, primarily based on sight, touch, hearing, smell, and operation. Certain aspects of a vehicle are difficult to accurately and reasonably evaluate using existing standards, or are affected by various factors, making it difficult to meet requirements. This leads to low customer satisfaction and a poor experience. For example, failing to conduct a sensory quality review at a key stage during the R&D phase can lead to significant costly changes later on.
[0003] Perceived quality differs from commonly understood concepts like process consistency and design satisfaction. Process quality and design quality are rational, objective, measurable, and absolute; whereas perceived quality is emotional, subjective, difficult to measure, and relative. These characteristics of perceived quality make it difficult to manage automotive product development using standard quality engineering methods. Only by translating perceived quality into measurable engineering terms can we achieve improvements in perceived quality during product development. Summary of the Invention
[0004] The technical problem to be solved by the present invention is: In order to overcome the above technical problems, the present invention provides a method for evaluating automobile perceived quality.
[0005] The technical solution adopted by the present invention to solve the technical problem is: a method for evaluating automobile perceived quality, comprising the following steps:
[0006] Step 1: Perceived quality goal setting: This includes comparative vehicle model perceived quality analysis, goal setting, goal decomposition, and achievement plan;
[0007] Step 2: Phase 1 Perceived Quality Target Verification: including virtual review and model review;
[0008] The virtual review is to conduct multiple rounds of problem review and improvement in each stage of early design and development to enhance the user's subjective experience, which is the best time to improve the perceived quality level;
[0009] The model review is to review and make design improvements through physical models to avoid perceived risks. The physical model is a physical part processed by a digital model that reflects the target shape and the overlap relationship between the actual parts;
[0010] Step 3: Second stage perceived quality target verification: including real vehicle review;
[0011] The actual vehicle review is to review, optimize and rectify the actual vehicle in the later stage to improve the consumer experience;
[0012] Step 4: Achievement of perceived quality goals: Based on the early design and development and the multiple rounds of problem reviews and improvements in the later actual vehicles, a target achievement report is prepared at each stage, and a summary of the sensory quality achievement is made after the project development is completed.
[0013] In step 1, comparison models are selected and their perceived quality is analyzed, resulting in a report and checklist. This perceived quality analysis includes both initial and in-depth analysis, optimizing the target product for the newly developed model by comparing the performance of the selected comparison models. Furthermore, through customer research processes and methods, customer needs and expectations are understood, further optimizing product design. Subsequently, perceived quality targets and target breakdowns are established for the newly developed model, along with a plan for achieving these targets. Initial analysis, conducted in the early stages of design and development, involves a theoretical analysis of the maturity of styling surfaces and design data. In-depth analysis, conducted after the physical components are installed on the vehicle, provides an actual analysis of their performance.
[0014] To achieve professional, engineered, and standardized management of perceived quality, it is necessary to design measurable standards for perceived quality. Once a perceived quality assessment system is established, standardized and reasonable perceived quality evaluations can be carried out at all stages of product design, enabling timely and accurate identification and proper handling of various problems and hidden dangers, thereby successfully achieving perceived quality goals. The following are the key steps in the perceived quality evaluation of vehicle development. Step 2 includes the following steps:
[0015] 21. Carry out perceptual quality evaluation of renderings based on the input renderings, output a list of perceptual quality issues of renderings, conduct problem review, design modification and avoidance of perceptual issues at the rendering stage;
[0016] 22. Conduct perceptual quality evaluation of clay models, output a list of perceptual quality issues of clay model evaluation, conduct problem review, design modification and avoidance of perceptual issues during the clay model stage;
[0017] 23. Conduct a C-surface perceptual quality evaluation and compile a list of perceived quality issues. During the C-surface phase, conduct issue review, design modifications, and avoidance of perceived issues. C-surface is a professional term for the exterior design surface of a model. Model surfaces are divided into A / B / C surfaces, and are a process of continuous refinement. The state of the C-surface reflects the separation and clearances between the various components of the model, representing the exterior surface of the model.
[0018] 24. Conduct a perceptual quality evaluation of M1 data, output a list of evaluation issues, and conduct problem review, design modifications, and avoidance of perceived issues during the M1 data phase. M1 data is the 3D assembly structure of internal components based on the exterior surface of the design. Initial design data is M1 data.
[0019] 25. Conduct a perceptual quality evaluation of CNC prototypes, generate a list of perceived quality evaluation issues, and conduct model reviews, design modifications, and avoidance of perceived issues. CNC prototypes are rapid prototyping parts (not open-die parts) created based on preliminary data. Physical installations are used to verify design deviations.
[0020] 26. Conduct M2 data perception quality evaluation, output a perception quality evaluation problem list and an M2 data node status list, and conduct problem review, design modification, and avoidance of perception issues during the M2 data stage. M2 data is mold opening data in a mature state. After the formal mold opening, this data represents the physical state of the component.
[0021] Steps 21, 23, 24, and 26 are the virtual review phase. After the vehicle design and 3D data are released, a virtual digital prototype is selected for review. The evaluation results are compared with the initial project goals, and perceived quality issues are recorded and a problem list is compiled. Problems are primarily resolved by adjusting and optimizing the digital model, without modifying the mold or tooling. Therefore, the cost is relatively low, and this is the best time to improve perceived quality.
[0022] Steps 22 and 25 are the model review stage. Because virtual data reviews are mostly visual, they cannot fully assess perceptual quality, such as tactile quality. Therefore, model review is essential. A physical model is obtained through processing, and this review is conducted to mitigate perceptual risks.
[0023] Step 3 includes the following steps:
[0024] 31. Conduct a perceived quality evaluation of PT prototypes, producing a perceived quality evaluation report and problem list. Review the issues identified in the actual vehicle and improve perceived quality. PT prototypes are the first test vehicles and verification prototypes for the production phase. The development time for each component varies. PT prototypes represent an initial stage where components have not yet reached mass production status and do not reflect styling, color, or texture.
[0025] 32. Conduct a perceived quality evaluation of tooling prototypes, output a perceived quality evaluation report for tooling prototypes and a list of issues with tooling prototypes, and improve perceived quality issues based on the review of actual vehicle issues. Tooling prototypes are parts produced using tooling and used for functional verification.
[0026] 33. Conduct a perceptual quality evaluation of leather textured vehicles and produce a perceptual quality evaluation report for leather textured vehicles. Leather textured vehicles are prototypes that reflect the actual vehicle's design, color, and texture, and include aspects such as appearance, leather texture depth, and color coordination.
[0027] 34. Conduct a perceived quality evaluation of small-batch prototypes, producing a perceived quality evaluation report and problem list for the small-batch prototypes. Based on the problem review of the full-batch production vehicles, optimize and resolve component quality issues. Small-batch prototypes are small-batch trial production prototypes prior to full-scale production.
[0028] Virtual reviews are largely limited to visual evaluations, making it difficult to comprehensively and deeply assess perceived quality, such as tactile assessments. However, physical prototype evaluations can effectively overcome these issues. In the later stages of project development, after vehicle production is complete, a physical vehicle perceived quality review is conducted, evaluating and correcting each item item by item. At this point, since the mold has already been opened, adjustments or design changes inevitably require significant investment. Therefore, it is crucial to maximize component fit and effectively improve part surface quality. Furthermore, this stage allows for a comprehensive dynamic perceived quality review encompassing various dimensions, including vehicle drivability, handling stability, and ride comfort. This ensures a robust consumer experience and promotes optimal perceived quality.
[0029] The physical model is a proportional physical model obtained by milling a digital model reflecting the target shape and the overlap relationship between actual parts into a solid part using polymer materials, and positioning and fixing it through a back structure.
[0030] The perceptual quality evaluation criteria in steps 2 and 3 are as follows: According to the perceptual quality evaluation specifications, each subjective evaluator scores each sub-item under the subjective evaluation item, and any unacceptable situation requires rectification.
[0031] The beneficial effect of the present invention is that the present invention provides a method for evaluating the perceived quality of an automobile, and the perceived quality work involves the entire process of vehicle development, starting from the project model positioning stage to the end of the project being put on the market. By constructing this evaluation method, the user's subjective needs are quantified into objective scores, and stage-by-stage quality control is carried out with the goal of achieving the target score. In the process of project development, problems are mainly discovered and identified through virtual digital model review, model review, and real vehicle model review, which can effectively improve the perceived quality of the automobile, enhance customer satisfaction, and thus improve the market competitiveness of the product. The present invention conducts a perceived quality review at each stage of vehicle development, and the key links of the early design are solved by adjusting and optimizing the digital model, without the need to modify the mold and tooling, so the cost is relatively low, and this is the best time to improve the perceived quality level. In the later stage, the actual vehicle undergoes a comprehensive and in-depth perceived quality review, and each item is evaluated and rectified to obtain a good perceived experience. BRIEF DESCRIPTION OF THE DRAWINGS
[0032] The present invention will be further described below with reference to the accompanying drawings and examples.
[0033] Figure 1 This is an evaluation flow chart of the automobile perceived quality evaluation method of the present invention.
[0034] Figure 2 It is a flow chart of the cooperation between the automobile perceived quality evaluation method of the present invention and the whole vehicle development node. DETAILED DESCRIPTION
[0035] The present invention will now be described in further detail with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.
[0036] like Figure 1 As shown, a method for evaluating automobile perceived quality of the present invention includes the following steps:
[0037] Step 1: Perceived quality goal setting: This includes comparative vehicle model perceived quality analysis, goal setting, goal decomposition, and achievement plan;
[0038] Step 2: Phase 1 Perceived Quality Target Verification: including virtual review and model review;
[0039] The virtual review is to conduct multiple rounds of problem review and improvement in each stage of early design and development to enhance the user's subjective experience, which is the best time to improve the perceived quality level;
[0040] The model review is to review and make design improvements through physical models to avoid perceived risks. The physical model is a physical part processed by a digital model that reflects the target shape and the overlap relationship between the actual parts;
[0041] Step 3: Second stage perceived quality target verification: including real vehicle review;
[0042] The actual vehicle review is to conduct a comprehensive and in-depth review, optimization and rectification of the actual vehicle in the later stage to improve the consumer experience;
[0043] Step 4: Achievement of perceived quality goals: Based on the early design and development and the multiple rounds of problem reviews and improvements in the later actual vehicles, a target achievement report is prepared at each stage, and a summary of the sensory quality achievement is made after the project development is completed.
[0044] In step 1, a comparison model is selected and the perceived quality of the comparison model is analyzed to form a report and list. The perceived quality analysis includes initial analysis and in-depth analysis. By comparing the performance of the selected comparison models, the target product of the newly developed model is optimized. At the same time, through customer research processes and methods, customer needs and expectations are understood, and product design is further optimized. Subsequently, perceived quality goals and goal decomposition of the newly developed model are formulated, and a plan for achieving the goals is formulated. Perceived quality goal setting includes goal decomposition, goal implementation plan and cost balance. Through target attribute analysis and solution analysis of specific models, a feasible technical route is formulated to ensure the achievement of perceived quality goals. Among them, the initial analysis is a theoretical status analysis conducted in the early stage of design and development based on the maturity of the styling surface and design data; the in-depth analysis is an actual status analysis conducted after the physical parts are installed on the vehicle.
[0045] To achieve professional, engineering, and standardized management of perceived quality, it is necessary to design measurable standards for perceived quality. After building a perceived quality evaluation system, standardized and reasonable perceived quality evaluation can be carried out in all aspects of product design, and various problems and hidden dangers can be discovered and properly handled in a timely and accurate manner, thereby smoothly achieving perceived quality goals. Figure 2 As shown in Figure 2, steps 2 and 3 are the key steps in the perceived quality evaluation of vehicle development.
[0046] Step 2 includes the following steps:
[0047] 21. Based on the renderings input by the modeling, conduct a perceptual quality evaluation of the renderings, output a list of perceptual quality issues in the rendering evaluation, conduct problem review, design modification, and avoid perceptual issues at the rendering stage.
[0048] 22. Carry out the perceptual quality evaluation of the clay model, output the list of perceptual quality issues of the clay model evaluation, and conduct problem review, design modification and avoidance of perceptual issues at the clay model stage.
[0049] 23. Conduct a C-surface perceptual quality evaluation and compile a list of perceived quality issues. During the C-surface phase, conduct issue review, design modifications, and avoidance of perceived issues. C-surface is a professional term for the exterior design surface of a model. Model surfaces are divided into A / B / C surfaces, and are a process of continuous refinement. The state of the C-surface reflects the separation and clearances between the various components of the model, representing the exterior surface of the model.
[0050] 24. Conduct a perceptual quality evaluation of M1 data, output a list of evaluation issues, and conduct problem review, design modifications, and avoidance of perceived issues during the M1 data phase. M1 data is the 3D assembly structure of internal components based on the exterior surface of the design. Initial design data is M1 data.
[0051] 25. Carrying out CNC sample car perception quality evaluation, outputting CNC sample car perception quality evaluation problem list, carrying out model review, design modification and avoiding perception problems. The CNC sample car is a rapid prototyping part (non-opening die part) made according to preliminary data, which is used to verify whether the design is deviated by physical installation.
[0052] 26. Carrying out M2 data perception quality evaluation, outputting perception quality evaluation problem list and M2 data node state list, and carrying out problem review, design modification and avoiding perception problems in the M2 data stage. The M2 data is the opening die data in the mature state of data, and the physical state of the part after the formal opening die is used.
[0053] Among them, steps 21, 23, 24 and 26 are virtual review stages. After the automotive styling design and 3D data are released, a virtual digital sample car is selected for standardized professional review. The evaluation results obtained are compared with the initial project goal carefully, and the perception quality problems are found and accurately recorded in time. The clear and standardized problem list is prepared to strengthen the tracking of the implementation of the solution. The problems generated are mainly solved by adjusting and optimizing the numerical model, without the need to modify the mold and tooling, so the cost is relatively low. This is the best opportunity to improve the perception quality level.
[0054] Steps 22 and 25 are model review stages. Since virtual data review can only be visual review, it cannot be a full range of perception quality review, such as tactile aspect, so model review must be carried out. The physical model is obtained by processing, and the physical model is reviewed to avoid perception risk problems.
[0055] Step 3 includes the following steps:
[0056] 31. Carrying out PT sample car perception quality evaluation, outputting PT sample car perception quality evaluation report and problem list, and improving quality perception problems according to real car problem review. The PT sample car is the first batch of test vehicles, and the verification sample car in the production stage. Each part development time is different, and the PT sample car is the initial state of the part that has not reached the mass production state, without reflecting the styling color and skin texture.
[0057] 32. Carrying out tooling sample car perception quality evaluation, outputting tooling sample car perception quality evaluation report and tooling sample car problem list, and improving quality perception problems according to real car problem review. The tooling sample car is a part produced by tooling, which is used for function verification.
[0058] 33. Carrying out skin sample car perception quality evaluation, outputting skin sample car perception quality evaluation report. The skin sample car is a sample car reflecting the design color and texture of the real car, involving appearance, skin depth, color coordination, etc.
[0059] 34. Conduct a perceived quality evaluation of small-batch prototypes, producing a perceived quality evaluation report and problem list for the small-batch prototypes. Based on the problem review of the full-batch production vehicles, optimize and resolve component quality issues. Small-batch prototypes are small-batch trial production prototypes prior to full-scale production.
[0060] Virtual reviews are largely limited to visual evaluations, making it difficult to comprehensively and deeply assess perceived quality, such as tactile assessments. However, physical prototype evaluations can effectively overcome these issues. In the later stages of project development, after vehicle production is complete, a comprehensive and in-depth physical vehicle perceived quality review is conducted, evaluating and correcting each item item by item. At this point, since the mold has already been opened, adjustments or design changes inevitably require significant investment. Therefore, it is necessary to maximize component fit and effectively improve part surface quality. Furthermore, this stage allows for a comprehensive dynamic perceived quality review encompassing various dimensions, including vehicle drivability, handling stability, and ride comfort. This ensures a robust consumer experience and promotes optimal perceived quality.
[0061] The physical model is a proportional physical model obtained by milling a digital model reflecting the target shape and the overlap relationship between actual parts into a solid part using polymer materials, and positioning and fixing it through a back structure.
[0062] The perceptual quality evaluation criteria in steps 2 and 3 are: Based on the perceptual quality evaluation specifications, a 10-point subjective evaluation is conducted. Each subjective evaluator scores each sub-item under the subjective evaluation item, and any unacceptable situation requires rectification.
[0063]
[0064] During the automotive product development process, the rational and effective discovery and identification of perceived quality issues is the first step in improving the perceived quality of the entire vehicle. This invention optimizes and improves existing perceived quality review methods and workflows, and has been validated through real-world projects to demonstrate their feasibility and effectiveness. Through application and implementation in multiple new vehicle development projects, this perceived quality evaluation method effectively translates market user language into engineering technical language, and quantifies it to engineering goals, thereby significantly improving user experience and satisfaction, and enhancing product competitiveness.
[0065] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
