| Abstract: | In this paper the detection errors of wheel speed signals are analyzed,the state space model of system for wheel speed estimation is built,and an adaptive Kalman filtering algorithm is adopted to estimate wheel speed.The effectiveness of the algorithm is verified by simulation with MATLAB.The real vehicle tests indicate that the filtered wheel speed signal has small time delay and quick response with relatively ideal smoothing effects and can be used for direct speed estimation. |
