Embodiment 1

[0050] see figure 1 , shows the method for determining the vehicle performance target in the first embodiment of the present invention, and the method specifically includes steps S01-step S04.

[0051] Step S01 , acquiring objective test values ​​of vehicle performance of multiple target vehicles and customer satisfaction of customers with respect to the vehicle performance, and the models of the multiple target vehicles are different.

[0052]In specific implementation, the development vehicle and the competing model of the same level as the developed vehicle can be used as the target vehicle, and the performance data of the developing vehicle and the competing model of the same level are to be fused and analyzed to improve the reliability of final performance target determination sex and effectiveness.

[0053] Among them, the vehicle performance may be but not limited to one or more of fuel consumption, power, NVH, space, and human-computer interaction. The objective test...

Embodiment 2

[0068] see image 3 , shows the method for determining the vehicle performance target in the second embodiment of the present invention, and the method specifically includes step S21-step S29.

[0069] Step S21 , acquiring objective test values ​​of vehicle performance of multiple target vehicles and customer satisfaction of customers on the vehicle performance, and the vehicle models of the multiple target vehicles are different.

[0070] Step S22, mapping the objective test value and the customer satisfaction into a preset two-dimensional coordinate system to obtain a plurality of discrete data points, the abscissa of the preset two-dimensional coordinate system is the objective test value, the vertical coordinate For customer satisfaction.

[0071] Step S23, performing curve fitting on the plurality of discrete data points to obtain a fitting curve, and determining a correlation function equation according to the fitting curve, and the correlation function equation is one ...

Embodiment 3

[0093] Another aspect of the present invention also provides a vehicle performance target determination device, please refer to Figure 6 , shows the device for determining the vehicle performance target in the third embodiment of the present invention, and the device for determining the vehicle performance target includes:

[0094] The data acquisition module 11 is used to obtain the objective test value of the vehicle performance of multiple target vehicles and the customer satisfaction of customers on the vehicle performance, and the models of the multiple target vehicles are different;

[0095] Correlation analysis module 12, is used for carrying out correlation analysis with described objective test value and described customer satisfaction, determines the correlation function equation between described objective test value and described customer satisfaction, and described correlation function equation is predicted Set one of the function equations;

[0096] Satisfactio...

Abstract

The invention provides a vehicle performance target determination method and device, a storage medium and equipment. The method comprises the steps: acquiring the objective test values of the vehicle performance of a plurality of target vehicles and the customer satisfaction of a customer for the vehicle performance, wherein the vehicle types of the plurality of target vehicles are different; performing correlation analysis on the objective test value and the customer satisfaction, and determining a correlation function equation which is one of preset function equations; performing normal distribution on all customer satisfaction degrees, and determining a target customer satisfaction degree of the vehicle performance according to a normal distribution curve of the customer satisfaction degrees and preset expectation information of the vehicle performance; and determining a target value of the vehicle performance according to the target customer satisfaction and the related functional equation. The determination of the performance target is closely related to the satisfaction degree of the customer, the setting is more reasonable, the problem of over-design or insufficient design of the vehicle is well solved, and the development cost can be used at the maximum efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle design, in particular to a method, device, storage medium and equipment for determining a vehicle performance target. Background technique [0002] Developing automotive products that satisfy customers is the ultimate goal pursued by every vehicle manufacturer and engineer, and vehicle performance is the only standard by which customers can directly perceive and evaluate the quality of a vehicle, but how to accurately grasp customer preferences and It is a big challenge for engineers to convert customer preferences into performance targets for engineering development. [0003] At present, major OEMs mainly have two methods for setting vehicle performance targets: one is the judgment method: the performance of each model that needs to be compared is displayed through objective data, and then compared to judge the pros and cons. The obvious disadvantages of this method It can only simply judge the ...
