[0019] The present application will be described in detail below in combination with the drawings and specific embodiments. The present embodiment is implemented on the basis of the technical scheme of the present application, and detailed implementation and specific operation processes are given, but the protection scope of the present application is not limited to the following embodiments.

[0020] English abbreviations involved: Sustainable Development Goal: SDG Fuzzy C-means Clustering: FCM Interval Analytic Hierarchy Process: IAHP Vehicle-to-Grid: V2G Nondominated Sorting Genetic Algorithm II: NSGA-II Embodiment 1 The present embodiment provides a sustainable electrified transportation optimization method based on unmanned driving, as shown inFigure 1 As shown, the method comprises the following steps: S1, obtaining the SDG targets related to sustainable electrified transportation in the current sustainable electrified transportation scheme, and obtaining the correlation scores of the index factors related to unmanned driving in the SDG targets, and constructing the correlation score interval.

[0021] Sustainable electrified transportation scheme refers to a transportation scheme designed in four dimensions of clean energy driving, electric vehicles, intelligent infrastructure, and low-carbon efficient operation.

[0022] The SDG targets related to sustainable electrified transportation include multiple targets in SDG3, SDG7, SDG9, SDG11, SDG12 and SDG13, and their specific associations are as follows: 1) SDG3: Good health and well-being Electric transportation helps improve air quality by reducing the use of fuel vehicles and reducing exhaust emissions, reducing respiratory system diseases and cardiovascular diseases caused by air pollution, thereby improving the overall health level of urban residents.

[0023] 2) SDG7: Affordable and clean energy The core of electric transportation is to use electric power to drive vehicles, and its sustainability depends on clean and renewable energy supply. This goal emphasizes the popularization of clean energy and promotes the transformation of energy structure to provide green power support for electric transportation.

[0024] 3) SDG9: Industry, innovation and infrastructure The development of electric transportation requires the construction of charging infrastructure, smart grid and new transportation systems, which is highly consistent with the "building of disaster-resistant infrastructure and promoting inclusive and sustainable industrialization" in SDG9.

[0025] 4) SDG11: Sustainable cities and communities Electric transportation is an important means to achieve sustainable urban transportation system, which can reduce traffic congestion, reduce noise and pollution, improve urban life quality, and support the goal of "providing safe, affordable and sustainable transportation systems to all".

[0026] 5) SDG12: Responsible consumption and production Electric transportation promotes the transformation of the transportation industry from traditional fossil energy to clean energy, reduces dependence on non-renewable resources, and promotes the popularization of green consumption and clean production methods, in line with the concept of sustainable consumption and production.

Electrified transportation directly supports the goal of SDG 13, "Taking urgent action to combat climate change and its impacts", by reducing carbon emissions, and is a key link to achieve carbon neutralization.

[0028] The index factors related to unmanned driving include safety, energy efficiency, carbon intensity, urban transportation efficiency, technology maturity, and research output.

[0029] Based on the SDG goals and corresponding subdivision specific SDG goals, the correlation analysis of unmanned driving and electric transportation is carried out. Considering that the subjective evaluation of experts often has uncertainty and fuzziness, it is difficult to fully reflect the true judgment by using a single numerical value, therefore, interval scoring form is adopted. According to the correlation score of the index factors related to unmanned driving in the SDG goals, the correlation score interval is constructed, and the correlation score interval is: In the formula, represents the number of evaluated SDG goals, represents that there are index factors related to unmanned driving in the SDG goals, is the th SDG goal, is the th index factor related to unmanned driving in the th SDG goal, is the lower bound of the correlation score interval of the th index factor related to unmanned driving in the th SDG goal, is the upper bound of the correlation score interval of the th index factor related to unmanned driving in the

[0030] th SDG goal.

[0031] The correlation score interval adopts 1-9 scale method, and the scale table is shown in Table 1. S2, according to the correlation score interval and the score confidence weight, the weighted score interval of each SDG goal is calculated.

[0032] The construction of score confidence weight is based on the following four dimensions: data support degree , field consensus degree , technology visibility and time verifiability . The data support degree is used to measure whether there is sufficient statistical data, research report or empirical support, the field consensus degree To ensure consistency in the correlation assessments of multiple experts regarding this indicator, technical visibility is crucial. This is used to measure whether the impact of autonomous driving technology on this indicator is intuitive, observable, and verifiable over time. Whether the current time conditions are suitable for verifying this impact.

[0033] For each indicator factor in the SDG objectives, calculate its score confidence weight, whereby the score confidence is: In the formula, For the first The first of the SDG objectives The confidence weights of the scores for each indicator factor related to autonomous driving. For the first Weight coefficients for each dimension This is the dimension for constructing the confidence weights of the ratings.

[0034] The weighted scoring range for SDG objectives is: In the formula, For the first The weighted scoring range for each SDG objective. For the first The lower bound of the weighted score for each SDG objective. For the first The upper bound of the weighted score for each SDG objective. For the first The first of the SDG objectives The confidence weights of the scores for each indicator factor related to autonomous driving.

[0035] S3. Construct a judgment matrix based on the weighted scoring interval, and solve the judgment matrix to obtain the initial weight vector interval of the indicator factors related to autonomous driving.

[0036] The Interval Hierarchical Analysis (IAHP) method is used to construct the structure. Judgment matrix : In the formula, To determine the first element in the matrix The SDG target is relative to the first The importance ratio range of each SDG target The judgment matrix is ​​solved using the interval eigenvector method to obtain the initial weight vector interval of the index factors related to autonomous driving. The initial weight vector interval is as follows: In the formula, For the first The first of the SDG goals The initial weight vector range of several indicators related to autonomous driving. For the first The first of the SDG goals The lower bound of the initial weight vector interval for each indicator factor related to autonomous driving. For the first The first of the SDG goals The upper bound of the initial weight vector interval for each indicator factor related to autonomous driving. This is the upper bound of the interval containing the largest eigenvalue. This is the lower bound of the interval containing the largest eigenvalue. To determine the first element in the matrix The SDG target is relative to the first j The lower bound of the importance ratio interval for each SDG objective. For the first The lower bound of the baseline weight vector interval for a number of indicators related to autonomous driving. To determine the first element in the matrix The SDG target is relative to the first The upper bound of the importance ratio interval for each SDG objective. For the first The upper bound of the baseline weight vector interval of a number of indicators related to autonomous driving.

[0037] S4. The initial weight vector intervals of the indicators related to autonomous driving are fused by the Adama product and normalized to obtain the final weight vector of each SDG target.

[0038] To effectively integrate the initial weight vector intervals of indicators related to autonomous driving and avoid the sensitivity of traditional arithmetic averages to extreme values, a geometric mean operator is used to integrate the weight vector intervals based on the Hadamard product concept. This reflects the synergistic effect and nonlinear compensation characteristics among the indicators. This process not only preserves the integrity of the weight vector intervals but also weakens the impact of individual data anomalies with large deviations, improving the robustness of weight allocation.

[0039] The final weight vector of the SDG objectives is: In the formula, For the first The final weight vector of each SDG objective. For the first The upper bound of the final weight vector of each SDG objective. For the first The lower bound of the final weight vector of each SDG objective.

[0040] S5. Calculate the weighted relevance score of each SDG objective based on the final weight vector and weighted scoring interval of the SDG objectives, and classify the weighted relevance score of each SDG objective into levels to obtain the relevance assessment results.

[0041] To capture both the best-case and worst-case scenarios simultaneously, and to allow policymakers to adjust the emphasis on the "upper limit" or "lower limit" based on their risk appetite, the weighted relevance score for SDG objectives is as follows: In the formula, For the first Weighted relevance scores of each SDG objective. For the first The upper bound of the weighted score for each SDG objective. For the first The lower bound of the weighted score for each SDG objective. This is a non-linear adjustment parameter with an adjustment range of 0-1. Its value reflects the contribution of the upper and lower bounds of the interval to the score. If... 5 indicates an optimistic bias, emphasizing the potential for integrated development; Taking a conservative approach, considering risks and uncertainties; if It is assumed that the contribution levels of the upper and lower bounds are equal.

[0042] Summary m The weighted scores of each objective constitute a vector set.
