研究了基于制动力和驱动力分配相结合的车辆稳定控制策略,即紧急避障时采用差动制动,高速超车时采用驱动力分配方法。采用二自由度车辆的横摆角速度作为参考,并与实测的横摆角速度相比较,根据比较结果采取相应的控制策略。应用虚拟样机技术建立车辆多体动力学模型,采用联合仿真的方法对控制策略进行仿真。仿真结果表明,采用基于制动力和驱动力分配相结合的车辆稳定控制策略可以大大提高加速超车和紧急避障时的操纵稳定性,这对减少高速行驶时道路交通事故的发生具有重要意义。

This paper presented a vehicle stability control strategy, which was integrated with active torque distribution and differential braking system. Differential braking system worked on high speed obstacle avoidance under emergency and active torque distribution operates on overtaking. Depending on the comparison results between the reference model and the actual vehicle, the stability control strategy choosed corre- sponding control method. The stability control simulation was performed on a multi--body dynamic model based on virtual prototyping. The results show that the stability control proposed herein can stabilize the vehicle on overtaking or high speed obstacle avoidance under emergency.
