摘要
轮胎-路面附着系数对于车辆主动安全控制系统设计与分析十分重要,本文中提出一种以鲁棒稳定性为设计目标的非线性观测器。通过分析轮胎侧向运动,建立数学模型,利用CarSim与Matlab/Simulink软件搭建联合仿真模型,实现鲁棒自适应观测器设计。通过仿真系统获取轮胎路面附着系数和轮胎侧偏角及相关信息,验证并分析所设计观测器的性能。
This paper presents a nonlinear observer with robust stability for tire-road adhesion coefficient, which is important for vehicle active safety control system. Establishing the mathematical model by analyzing tire lateral motion. Then build a co-simulation system to bring about robust adaptive observer by Carsim and Matlab/Simulink. Use the system to obtain and verify the related information of tire-road adhesion coefficient and tire slip angle
