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.
