Therefore, how to improve the operational efficiency of vehicles and reduce unnecessary waste of resources through technical means has become an urgent problem to be solved. Especially for enterprises with a large fleet, being able to monitor and optimize the operating status of each vehicle in real time is crucial to improving overall operational efficiency.
[0003] At present, some solutions on the market have attempted to improve vehicle operation efficiency through data analysis, such as collecting data through GPS tracking of vehicle location, fuel consumption monitoring, etc., and using these data for simple statistical analysis to guide scheduling decisions.

[0154] 102. Classify the multiple operating parameters according to the degree of influence on the vehicle operating efficiency to obtain multiple types of operating parameter combinations;
[0155] Optionally, the step 102 of classifying the multiple operating parameters according to the degree of influence on the vehicle operating efficiency to obtain multiple types of operating parameter combinations includes: identifying the degree of influence of parameters among the multiple operating parameters; and combining parameters with the same degree of influence to obtain at least one type of operating parameter combination.

[0183] Get the historical dataset:
[0184] Specific operations: Collect vehicle operation data for the past year, including parameters such as speed, acceleration, fuel consumption, and driving distance.
[0185] Example: Assume the historical data set is as follows:
[0186] Historical Dataset = {
[0187] "vehicle speed": [80,81,82,...,85],
[0188] "acceleration": [2,2.1,2.2,...,2.5],
[0189] "Fuel consumption": [10, 10.2, 10.5, ..., 11],
[0190] "Driving distance": [120,121,122,...,125]

[0209] Multiple types of operation parameter combinations = {
[0210] "Great impact": ["vehicle speed", "fuel consumption"],
[0211] "Medium Impact": ["Acceleration"],
[0212] "less impact": ["driving distance"]
[0213] }
[0214] Through the above embodiments, the logistics company can reasonably classify the operation parameters according to the influencing factors evaluated in the historical data set to form a combination of multiple types of operation parameters, thereby providing support for subsequent feature extraction and strategy optimization.
[0215] 103. Extracting feature vectors corresponding to the parameters in the plurality of types of operation parameter combinations, wherein the plurality of types of operation parameter combinations are arranged in order of influence from greatest to least;
[0216] In this step, we will focus on how to extract the feature vectors from the operating parameter combinations and rank them according to their impact on vehicle operating effectiveness and cost-effectiveness.
[0217] Feature vector: Combines multiple operating parameters into a vector to represent the status of vehicle operation.
[0218] Suppose we are developing a comprehensive optimization method for the full-link vehicle operation efficiency for a logistics company. We need to extract useful features from the actual operation data of the vehicle and rank them according to their importance in order to further optimize the operation strategy.
[0219] Collect operational parameters:
[0220] First, we collect the following types of operational parameters: average speed ( ), fuel consumption rate ( ), load ( ), driving distance ( ), maintenance interval ( ).
[0221] Define the eigenvector:
[0222] For each car, we define a feature vector that contains all the above parameters. For example, the feature vector of a car can be expressed as [ ].
[0223] Calculate the impact:
[0224] In order to determine the impact of these parameters on vehicle operating efficiency and cost-effectiveness, we can use a variety of statistical methods or machine learning models. Here we take multivariate linear regression as an example:
[0225] ;
[0226] in, It is a quantitative indicator of cost-effectiveness. is the intercept term, to is the regression coefficient, is the error term.
[0227] Sort the eigenvectors:
[0228] By training the model, we can get the regression coefficient of each parameter The absolute values of these coefficients reflect the degree of influence of the parameters on cost-effectiveness. For example, if , it means that fuel consumption rate has the greatest impact on cost-effectiveness, followed by average speed, and so on.
[0229] Application sorting results:
[0230] Based on the results of the impact ranking, we can reorganize the order of the feature vectors to better understand which factors need the most attention. For example, the new feature vector can represent [ ].
[0231] Example numericalization:
[0232] Suppose we have a set of data as follows:
