| 摘 要： | 针对车辆安全稳定系统的算法设计中诸如车身质心侧偏角等惯性信息难以估量的问题,研究了状态观测器在系统中的应用方法。建立了车辆二自由度单车道数学模型,设计了质心侧偏角状态观测器的流程,并对此流程中的估算条件和影响因素进行了计算分析。通过数值计算类软件Matlab和动力学仿真类软件Adams的联合仿真,验证了所设计的状态观测器的精度能够满足车辆安全稳定系统的算法设计中的要求。

| Abstract: | The state observer method is applied in the vehicle safety and stability systems to solve the problem such as the inertial information of yaw angle which is immeasurable.The two degrees of freedom vehicle mathematical model is established and the yaw angle state observer process is designed.The estimated conditions and influence factors used in the process are calculated.The numerical calculation software Matlab is combined with the dynamics simulation software Adams to establish the co-simulation environment to verify the precision of the state observer satisfy the requirements of the algorithm in the vehicle safety and stability system. |
