The invention provides a vehicle energy-saving driving behavior evaluation method and system, and relates to the technical field of vehicle driving behavior evaluation.According to the method, in the energy-saving driving evaluation process, vehicle driving data and vehicle navigation data of a target vehicle within a preset historical time period are obtained; the method comprises the following steps: dividing vehicle driving data into a plurality of types of driving conditions, finally extracting characteristic parameters based on a maximum information coefficient, outputting driving behavior strategies corresponding to different driving conditions according to vehicle energy consumption and a change rule of the characteristic parameters, and finally realizing classified prediction of driving energy consumption through a logistic regression model. And performing score conversion on the prediction classification result to realize energy-saving driving behavior evaluation. The invention aims to improve the evaluation precision of energy-saving driving evaluation through multi-dimensional calculation, so that the driving strategy is better output, and the user experience is improved.

    本发明提供了一种车辆节能驾驶行为评价方法及系统,涉及车辆驾驶行为评价技术领域,所示方法在进行节能驾驶评价的过程中,通过获取目标车辆在预设历史时间段内的车辆行驶数据与车辆导航数据,将车辆行驶数据划分成若干类行驶工况,最后基于最大信息系数提取特征参数,根据车辆能耗与特征参数的变化规律,输出不同行驶工况对应的驾驶行为策略,最后通过逻辑回归模型实现驾驶能量消耗的分类预测,以及将预测分类结果进行分数转换以实现节能驾驶行为评价。本发明旨在通过多维度计算提升节能驾驶评价的评价精度,从而更好的输出驾驶策略,提升用户使用体验性。
