卡车ABS复合逻辑门限控制方法研究

Research on the Composite Logic Threshold Control Method of Truck ABS

针对传统卡车制动防抱死系统控制逻辑复杂、门限值之间缺乏联系、易受干扰、车型难匹配等问题,通过分析每个逻辑门限值对制动效果的影响,结合大量实验数据将传统的逻辑门限控制方法改进为复合逻辑门限控制方法。该方法使用一个复合逻辑门限参数来反映车轮的抱死趋势,并以此为制动压力调节依据。实验证明,采用该方法设计的ABS控制器降低了车型匹配难度,具有良好的控制效果。

Aiming at the problems of the traditional truck ABS such as complex control logic, lack of contact between the threshold values, susceptible to interference as well as models matching difficulty, investigates the effects of logic threshold on the braking and combines a large number of experimental data to transform the traditional logic threshold control method into the composite control method. The proposed method applies a composite logic threshold parameter to reflect the tendency to lock the wheel, and with it as the basis to regulate the brake pressure. Experimental results show that the designed ABS controller reduces vehicle matching difficulty and has good control effect.
