Abstract:

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.
