Problems solved by technology

[0007] At present, the design of product families is generally led by industrial designers, relying on personal subjective aesthetics and experience, and lacking computer support. The product family design scheme cannot meet the diverse needs of consumers
If not properly planned, these will lead to excessive differences among series models, which will not be conducive to creating a consistent visual image of product families. This contradiction is particularly sharply reflected in modern industrial design, especially for emerging companies that have not established a complete product family strategy

Embodiment

[0064] 1) Extract and express the SUV appearance gene;

[0065] 1.1) The shape culture method is used to express the personalized gene of SUV shape, that is, the side contour line. The side profile of the SUV is composed of two smooth Bezier curves, such as figure 1 As shown, curve 1 extends from the front of the car to the end of the hood, including 3 hard points and 2 control points; curve 2 starts from the bottom of the windshield, extends through the roof to the rear, and includes 4 hard points and 4 control points . Use HP (Hard Point) to represent hard points, and CP (Control Point) to represent control points.

[0066] The selection of SUV samples is to select 60 most popular SUV models from the Chinese auto market based on sales, popularity and word of mouth, and use the analytic hierarchy process to eliminate SUV models with similar appearance, and then import the data obtained by the analytic hierarchy process into SPSS software for clustering Finally, 16 typical ...

Abstract

The invention discloses a method for SUV (Sport Utility Vehicle) product family gene evolution based on genetic algorithm. The method includes: through abstracting and expressing SUV appearance individualized genes and SUV appearance successional genes, building SUV product lines with differential SUV designed styles and consumer-preference-driven evolution function according to different consumer preferences, generating optimal individualized gene progenies in Matlab based on the genetic algorithm, realizing evolution of the SUV appearance individualized genes, adding SUV appearance inheritance genes to the evolutional genes, realizing overall application of SUV product family appearance genes, generating a series of product design schemes, and building product family images with continuation and differentiation.

Description

technical field [0001] The invention relates to gene evolution of SUV product family, in particular to a method for gene evolution of SUV product family based on genetic algorithm. Background technique [0002] China's auto industry is experiencing an unprecedented period of rapid development. In 2011, the annual sales volume of automobiles in China exceeded 18 million, becoming the largest automobile market in the world. The production and sales growth rate of SUV (Sport Utility Vehicle) models was astonishing, and they were more and more favored by consumers, which aroused the interest of the market and businessmen. extensive attention. [0003] With the increasing homogeneity of functions and technologies, the appearance design of vehicle models has gradually become a decisive factor affecting consumer decision-making. Major automobile brands are also shaping their own brand images by giving products unique design features, making product appearance design It has brand ...
