考虑侧偏接地特性的轮胎侧偏角估计
Estimation of tire sideslip angle considering sideslip grounding characteristics
摘要
Abstract
As a critical state variable characterizing tire-road interaction,tire sideslip angle is essential for vehicle stability control as well as vehicle state and parameter estimation.This paper proposes a sideslip angle estimation method based on a BP neural network.First,a finite element model of a 205/55R16 radial tire was developed using ABAQUS software.A tire static test bench was built and the model's validity was verified by comparing vertical stiffness curves.Next,under steady-state rolling conditions,various sideslip angle parameters were set to analyze the changes in tire contact characteristics.Finally,based on the data obtained under sideslip conditions,a neural network model for sideslip angle prediction was developed.Results show the proposed model effectively predicts the tire sideslip angle with good generalization capability and accuracy,providing some insights into vehicle stability control.关键词
