摘要
以协调车辆各类动力学特性为目标,通过研究双重转向、机动性和稳定性的控制参数,设计了基于模糊逻辑的控制目标融合算法,得到了全车速工况动力学控制目标.在此基础上,利用15自由度车辆模型,针对不同路面附着系数、不同转向操作、不同车速工况条件,对控制目标的实际效果进行仿真研究.结果表明,所设计的控制目标能够反映车辆不同车速下的动力学需求,对改善车辆动力学特性有明显效果.
Aiming at the coordination of the different dynamic characteristics, a control target was designed based on fuzzy logic strategy to coordinate the objectives of dual-steering and improve maneuverability and stability. Simulation analyses with different road adhesion coefficients, steering operations and vehicle speeds were carried out based on 15DOF vehicle model. The results of simulation show that the control objective can satisfy dynamics demands of vehicle in various speeds, and the control system is effective to improve the dynamics capabilities of all-wheel independent electric drive vehicle.
