Abstract:
Because vehicle movement exists nonlinear characteristics, this paper adopted relevance vector machine(RVM)to estimate the vehicle state. The test time of relevance vector machine is shorter than support vector machine(SVM)and the amount of computation is smaller than SVM. In order to estimate vehicle state accurately, Kalman filter was used to filter yaw rate and velocity data after collecting the test data. The filtered data were regarded as the input of relevance vector machine. Then the maximum likelihood function was established according to Bayesian theory. The difference between the change of yaw rate and velocity data was considered. The optimal number of iterations could be determined by gamma values, values difference and the maximum likelihood values in different iterations so as to guarantee the shorter testing time and higher hit probability of this model. Finally, the validation of the model was proved. The results show that this model can approximate to the true values of the estimated samples more accurately. The yaw rates with greater volatility need more number of iterations, gamma values and values change more rapidly, and the convergence speed is faster. 2 tabs, 9 figs, 11 refs.
