| Abstract: | The three-axle vehicle is researched. The 2-DOF model of three-axle vehicle is founded. Based on zero side-slipping angle, the control stability of whole steering system and forward two-axle steering system was simulated and compared by MATLAB/Simulink on time domain response using the method of the fixed turning angle ratio of the forward wheel to the trailing wheel and the method of the fuzzy control actualizing vehicle control. The result shows that the whole steering technology can decrease the steering radius at low speeds and improve vehicle stability at high speed. |
