| 摘 要： | 建立了某四轮汽车9自由度车辆模型和轮胎动力模型,并提出了一种基于侧向力利用系数的差动制动、主动转向切换控制策略。模拟了汽车以车速24.5m/s行驶时的一个紧急避让情况,研究了无控制模式、差动制动控制模式、联合控制模式下的车辆横摆角速度、质心侧偏角、质心侧向位移的变化。结果表明,所提出的差动制动联合主动转向技术的控制策略可以满足变路面下车辆稳定性控制要求。

| Abstract: | A 9 degree-of-freedom vehicle model and a tire dynamic model for a four-wheeled vehicle is established in this paper,and a differential braking and active steering switch control strategy based on lateral force utilization coefficient is presented.An emergent collision avoidance situation at the speed of 24.5m/s is simulated,the change of vehicle yawing velocity,centroid slip angle and centroid lateral displacement in the uncontrolled mode,differential braking control mode and united control mode is researched.The results show that the proposed united control strategy combining differential braking and active steering technology can satisfy the requirement of vehicle stability control in varying road surface. |
