改进型ABS对汽车侧向稳定性的影响

Impact of Improved ABS to Lateral Stability of Vehicle

汽车转弯制动时,由于左右车轮载荷的变化,经常导致车辆过多转向而丧失方向稳定性,可以通过改进汽车上普遍采用的ABS制动防抱死系统的控制策略来保持车辆在转向制动时的侧向稳定性。通过对传统ABS系统和改进型ABS的详细比较,说明了可在传统的ABS系统的基础上,通过修改控制策略中弯道内、外侧车轮的目标滑移率来实现汽车横向稳定性的控制,使ABS部分代替ESP的作用。

When automobile was braking in a turn, since the left and righ! wheel load changed, excessive turning often led to loss of ve-hicle steering stability. By improving the control strategy of anti-lock braking system （ABS） widely used in vehicles, tile steering-braking lateral stability was maintained at turning braking. Through detailed comparison of traditional ABS and implvved ABS, it was shown that based on the traditional ABS system, by modifying the target slip ratio of outside wheel in turning track of control strategy, the transverse stability control of vehicles was implement. So part of the ESP fuuclion is substituted by the ABS.
