Problems solved by technology

[0004] However, the importance of each safe driving indicator is pre-estimated, and there may be a lot of subjective factors in the pre-estimation process, so the pre-estimated importance may not be able to objectively and accurately reflect the actual importance of each safe driving indicator. degree

Abstract

The embodiment of the invention provides a safe driving index weight determination method and a device, and electronic equipment. The method comprises the steps that based on scores of a plurality ofdrivers on a plurality of safe driving indexes, calculating entropy values of the plurality of safe driving indexes respectively, and the entropy value of each safe driving index is used for representing the dispersion degree of the scores of the plurality of drivers on the safe driving indexes; and determining a comprehensive weight of the safe driving index based on the entropy of each safe driving index in the plurality of safe driving indexes, the comprehensive weight of each safe driving index being negatively correlated with the entropy of the safe driving index. The entropy value is obtained by counting the dispersion degree of scores of a plurality of drivers on a safe driving index; the information carried by the safe driving index and the relative advantages and disadvantages ofa plurality of drivers on the safe driving index can be quantitatively expressed, so that the comprehensive weight can objectively and accurately reflect the actual importance degree of the safe driving index.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method, device and electronic equipment for determining the weight of a safe driving index. Background technique [0002] Whether the driver's driving behavior in the process of driving a vehicle conforms to the principle of safe driving directly affects the safety of road traffic. In order to better control the driver's driving behavior and improve the safety of road traffic, the driver's driving behavior can be evaluated. [0003] In the prior art, sensors in the vehicle can be used to obtain the driving behavior data of the driver during driving, and the driving behavior data can be analyzed to determine the number of times the driver has violated the principle of safe driving during the driving process. According to the number of times of various driving behaviors that violate the safe driving principle within the unit driving distance, the score of the ...
