| Abstract: | The running states on two degrees of freedom of vehicle were estimated using Kalman filter.The simulation results show the estimated value and true value tally well.In addition to base assist current,yaw rate current compensation and slide angle current compensation were conducted.The simulation results show road feel is improved,slide trend is restrained and the running stability of vehicle is enhanced. |
