摘要
以递进式最小二乘法理论为基础,将汽车行驶过程中的轮胎侧偏刚度作为未知参数进行估算,完成汽车参数自动调节,防止汽车质心侧偏角的估算值误差过大,而出现不必要的操作.最终在Matlab/Simulink环境下建立控制模型,对车辆前后轮侧偏刚度及质心侧偏角控制算法进行仿真验证.对比后发现,车辆质心侧偏角的估算效果非常接近真实结果,可以满足汽车稳定性控制系统的估算,可有效提高汽车主动安全性.
Based on the progressive least squares theory,the tire lateral stiffness was estimated as unknown parameter in the drivingprocess.The vehicle parameter was automatically adjusted to prevent big error of sideslip angle which leads unnecessary operation.Finally,a control model was established in Matlab/Simulink environment,and the control algorithm of lateral stiffness of tires and sideslip angel was simulated.The simulation results show that the estimation effect of sideslip angle is very close to the real result,whichcan meet the estimation of vehicle stability control system and improve the active safety of automobile.
