摘要
以三轴全轮转向车辆为对象进行了转向控制系统分析,建立了三轴车辆转向二自由度单轨模型,利用MATLAB/Simulink,基于零质心侧偏角控制目标,分别采用定前后轮转角比控制方法和模糊控制方法进行了转向控制系统时域仿真,并与前两轴转向车辆进行了对比.结果表明:采用全轮转向技术,减少了车辆低速转向时的转向半径,提高了高速转向稳定性.
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.
