| 摘 要： | 研究了基于轮胎纵向制动力与侧向力动态分配的车辆稳定性控制策略，即根据车辆实时的运动状态调整前后轮纵向力与侧向力的值，从而产生变化的横摆力矩。采用二自由度的车辆横摆角速度作为参考值，与实际的横摆角速度进行比较，同时根据前后轮纵向力与侧向力对横摆角速度的作用，确定前后轮纵向力与侧向力的比值。最后与传统的单一纵向制动力调节进行比较，该控制方法不仅在能够在较低附着路面上进行横摆稳定性调节，而且实时的变纵向力与横向力比值调节，能够更快地使车辆回到理想的运动状态。

| Abstract: | The vehicle stability control strategy was presented, which was based on the dynamical allocation ot the lateral lorce and longitudinal braking force. According to the vehicle real-time motion state, the longitudinal force and lateral value of the front and rear wheel were adjusted, thereby a variable yaw moment was generated. The yaw velocity of the 2-degree model was adopted as reference value, and was compared with the real one. Meanwhile, under both the front and rear longitudinal force and lateral force on the role of yaw rate, the ratio of the longitudinal force and lateral force of the front and rear wheels was determined. Finally compared with the traditional single longitudinal braking force regulator, the control method is not only capable of yaw stability regulation on a bad road, but of real-time change in the longitudinal force and lateral force of ratio adjustment. It is possible to make the vehicle back to the ideal exercise state faster. |
