Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] Such as figure 1 As shown, a method for determining the curb weight of a newly developed model includes the following steps:
[0032] Step 1. Obtain the curb data set of competing models in the curb quality control system. The curb data set of competing models includes the curb weight data of each competing model and the characteristic parameter data related to the curb weight. For example, the length of a competing car ,Width Height. The curation data set of competing models in a specific example is shown in Table 1:
[0033] Table 1. Data set of curation of competing models

The invention discloses a reconditioning quality determination method and decomposition method for a newly developed vehicle model. The method comprises the following steps: 1) obtaining a reconditioning data set of competitive vehicle models; 2) acquiring characteristic parameter data of a newly developed vehicle model, and matching in the reconditioning data set of the competitive vehicle modelto obtain a matched competitive vehicle model and related characteristic parameter data; 3) obtaining the surface area of the matched competitive vehicle type, and calculating the nominal density of the competitive vehicle with the unit surface area of the competitive vehicle; 4) determining nominal density of a newly developed vehicle model; 5) calculating the surface area of the newly developedvehicle model according to the length, width and height parameters of the newly developed vehicle model to obtain the servicing mass of the newly developed vehicle model; 6) after determining the servicing quality of the newly developed vehicle model, decomposing the servicing quality of the newly developed vehicle model. According to the method, the problems of reconditioning quality definition and decomposition in the whole vehicle development process are solved, the data has comparability and traceability, and the accuracy of determining the reconditioning quality of the newly developed vehicle model is improved.
Description
technical field [0001] The invention relates to the lightweight technology of the whole vehicle in automobile manufacturing, in particular to a method for determining the curb weight of a newly developed vehicle model and a method for decomposing it. Background technique [0002] The existing methods for determining the curb weight of newly developed models are to establish a model of the weight of the entire vehicle by analyzing the data and combining the key features of the entire vehicle to obtain the curb weight of the corresponding model. For example, based on the data of multiple competing products in the market, calculate the weight coefficient of the model of the competing product, select a smaller weight coefficient of the competing product to fit with the time to market, deduce the weight target of the model to be developed according to the fitting curve, or analyze the existing Based on the data of competing models, the key parameter with the highest correlation w...
