In this paper, the new type of active roll stabilizers are mounted on the front and rear axle of an experimental medium-duty truck, which are connected to the frame through their hydraulic actuators.

The air ABS of medium-duty truck studied in this thesis included three parts: braking pressure adjustor, rotate speed sensor of wheel and electronic control unit (ECU).

According to the character of medium-duty truck and the air braking system, the thesis studied concretely the structure project and control method of medium-duty truck's air ABS.
