摘　　要：为确定全轮转向重型车辆高速失稳边界,采用非线性控制理论研究了车辆失稳区域的确定方法。针对某双前桥转向三轴车辆,研究其相平面特性的影响因素,选取能够较好描述车辆高速稳定性状态的相平面。基于选取的车辆高速稳定性表征相平面,分析其稳定性影响因素,并确定稳定性区域。To determine the high speed instability boundary of heavy-duty vehicle,the method of determining the instability area of vehicle with the non-linear control theory is studied.For a dual-front-axle steering three-axle vehicle,the influencing factors of its phase plane characteristics are studied,and the phase plane which can better describe the high-speed stability state of the vehicle is selected.Based on the selected phase plane which characterizes the high-speed stability of the vehicle,the influencing factors of its stability are analyzed and the stability region is determined.
