The invention discloses a driving behavior evaluation method and system based on Internet of Vehicles, and a storage medium, wherein the method comprises the following steps: step 1, extracting user behavior data from an Internet of Vehicles database; step 2, repeatedly screening the characteristic variables by using stepwise regression until an explanatory variable with optimal significance is screened out; step 3, performing variable binning on the characteristic variables, performing WOE conversion on the characteristic variables to complete independent variable construction, performing training by using a logistic regression model to obtain a trained model, and outputting variable parameters of the model; step 4, according to a score card conversion method, scores of the four dimensionvariables including the driving habit, the charging habit, the safety and the energy consumption are output, and the higher the scores are, the better the driving behavior is; and step 5, weighting the scores of the four dimension variables to obtain a final driving behavior score, performing grade conversion, and outputting a driving behavior grade. According to the invention, the driving behavior is rated comprehensively according to the driving habit, the charging habit, the safety and the energy consumption.
本发明公开了一种基于车联网的驾驶行为评价方法、系统及存储介质,包括:步骤1.从车联网数据库中提取用户行为数据;步骤2.使用逐步回归对特征变量进行反复筛选,直到筛选出显著性最优的解释变量;步骤3.对特征变量通过变量分箱,再对特征变量进行WOE转换完成自变量构造,使用逻辑回归模型进行训练,得到训练后的模型,输出模型的变量参数;步骤4.根据评分卡转换方法,输出驾驶习惯、充电习惯、安全性以及能耗这四个维度变量的分值,分值越高,表示驾驶行为越好;步骤5.将四个维度变量得分进行加权,得到最终的驾驶行为得分,并进行等级转化,输出驾驶行为评级。本发明从驾驶习惯、充电习惯、安全性和能耗综合对驾驶行为进行评级。
