The invention relates to the technical field of driving behavior data processing, and discloses a heavy truck driving behavior data processing method and device, equipment and a medium, and the method comprises the steps: firstly obtaining a driving behavior vector of a to-be-evaluated object; then the driving behavior vector is input into a driving style recognition model, the driving style recognition model comprises a multi-level cascade model, and the cascade model comprises a plurality of sub-models; performing primary feature mapping on the driving behavior vector by using a plurality of sub-models of a first level to obtain a first probability set; and then inputting the driving behavior vector and the first probability set into a second hierarchy, performing advanced feature fusion by using a plurality of sub-models on the second hierarchy to obtain a second probability set, finally determining a target driving style of the to-be-evaluated object based on the second probability set, and generating performance assessment data of the to-be-evaluated object based on the target driving style. Through a multi-level cascade structure, the driving behavior characteristics are gradually optimized and enhanced, so that the accuracy of the performance assessment data of the to-be-assessed object is improved.

    本申请涉及驾驶行为数据处理技术领域,公开了一种重型货车驾驶行为数据的处理方法、装置、设备与介质,首先获取待评估对象的驾驶行为向量;然后将驾驶行为向量输入至驾驶风格识别模型,包括多层级的级联模型,级联模型包括多个子模型;接着利用第一层级的多个子模型分别对驾驶行为向量进行初级特征映射,得到第一概率集合;再接着将驾驶行为向量和第一概率集合输入第二层级,利用第二层级上的多个子模型进行高级特征融合,得到第二概率集合,最后基于第二概率集合确定待评估对象的目标驾驶风格,并基于目标驾驶风格生成待评估对象的绩效考核数据。通过多个层级的级联结构,逐步优化和增强驾驶行为特征,从而提升待评估对象绩效考核数据的准确度。
