路面不平度对装有ABS汽车制动性能的影响

为了揭示在汽车制动过程中路面冲击对装有ABS汽车制动性能的影响,建立了计及路面不平度的汽车整车动力学模型.在该模型中路面不平度利用随机的四轮路面输入来实现.结合常规的ABS逻辑门限控制策略进行了路面不平度对装有ABS汽车制动性能影响的仿真研究.通过数值模拟实例结果得到了制动过程中路面不平度对装有ABS汽车制动性能造成的影响,为可靠有效地设计汽车ABS控制策略提供了依据.

Effects of Uneven Road Profile on the Braking Performance of Automobiles Equipped with ABS

In order to demonstrate the effects, the uneven road profile was taken into account and a vehicle model was developed with the consideration of uneven road profile. The effects of uneven road profile were realized by the application of stochastic four-wheel road uneven input. Finally, in conjunction with the conventional ABS logic threshold control strategy, a simulation was conducted to analyze the effects of uneven road profile on the braking performance of automobiles equipped with ABS. It is shown through the simulation results that the effects are obvious. It is viable to design more effective ABS control strategy based on the results.
