| Abstract: | Based on the present research of the vehicle handling inverse dynamics, the algebraic algorithm of real neural network is used to study the inverse dynamics. According to the motion differential equations and double line road model of two degrees of freedom vehicle open-loop system model, to solve the ＂forward problem＂, the samples achieved are input into real neural network for training. The training process of the algorithm network is compared with BP, and the result shows the superiority of algebraic algorithm. Another set of simulation which can identify successful network is input, the achieved car steering wheel angle is compared with the simulation results, so as to verify the accuracy of network. At last, real vehicle experiment is carried out, the test data is compared with the neural network identification result, again to verify its accuracy. |
