为了在制动防抱死仿真研究中取得良好的控制效果,逻辑门限值控制方法中的最佳门限值会随着车速和路面附着系数的情况变化而变化。以研究自调节门限值的控制方式为目的,在 MATLAB软件中创建了双轮三自由度车辆模型以及有效的逻辑门限值控制策略。在不同车速及不同附着系数的路面进行了仿真试验,并且选取车轮滑移率和车轮速2个重要参数进行考察,通过对最佳滑移率持续时间以及车轮的转动稳定性分析,验证了该自调节门限值控制的有效性。
為瞭在製動防抱死倣真研究中取得良好的控製效果,邏輯門限值控製方法中的最佳門限值會隨著車速和路麵附著繫數的情況變化而變化。以研究自調節門限值的控製方式為目的,在 MATLAB軟件中創建瞭雙輪三自由度車輛模型以及有效的邏輯門限值控製策略。在不同車速及不同附著繫數的路麵進行瞭倣真試驗,併且選取車輪滑移率和車輪速2箇重要參數進行攷察,通過對最佳滑移率持續時間以及車輪的轉動穩定性分析,驗證瞭該自調節門限值控製的有效性。

In order to get good control effects in anti-braking simulation study,the logic gate of logic gate limiting value control will be changed with the change of speed and road adhesion coefficient.The vehicle model with wheeled three de-grees of freedom and effective logic gate limiting value control strategy were created in MATLAB for research on self-adj ust-ment logic gate control.Simulation tests were carried out for multiple speeds of cases and variety of road adhesion coeffi-cient.Did simulation tests under different vehicle speed and different adhesion coefficient,and did observation selecting two important parameters,which were slip rate and wheel speed,through the analysis of duration of best slip rate and stability of wheel rotation,testified the effectiveness of self-adj ustment logic gate limiting control.
