摘　　要：轮胎配套选型是整车开发过程中的重要环节,目前主流的主观评价方法存在企业间规范一致性差、车手资源紧缺以及评价节点滞后等问题。本文基于实车主客观测试评价数据,考虑轮胎力学性能和结构参数与整车操纵稳定性的内在关联,通过相关性分析提取主观评价影响因子并生成降维特征空间,建立了主客观融合评价体系。进一步以客观指标与主观评分先验趋势关系为约束惩罚项,通过设计集成学习算法构建基于主客观融合的轮胎与整车操纵稳定性匹配评价模型,在多区域测试数据上的MSE均值为0.247,预测结果与测试结果表现出较好的一致性。相关成果可以构建整车操稳主客观一致性量化评价体系,为轮胎配套精确选型提供支持。Tire matching selection is an important part of the vehicle development process.Currently,the mainstream subjective evaluation methods have problems such as poor consistency between enterprises,shortage of driver resources,and lagging evaluation nodes.In this paper,based on the subjective and objective test data of real vehicles,considering the inherent correlation between tire mechanical performance and structural parameters of vehicle handling stability,by extraction of subjective evaluation influencing factors and generation of the dimensionality reduction feature space based on correlation analysis,a subjective and objective fusion index system is established.Further,with the objective indicators and subjective rating prior trend relationship as the constraint penalty term,a tire and vehicle handling stability matching evaluation model based on subjective and objective fusion is constructed by designing an ensemble learning algorithm.The mean MSE on multi region test data is 0.247,and the predicted results show good consistency with the test results.The relevant achievements can build a quantitative evaluation system for the subjective and objective consistency of vehicle handling stability,providing support for precise selection of tire matching.
