The invention discloses a dual-redundancy type drive-by-wire pneumatic and hydraulic braking system which comprises a first power assisting module. The active safety module is integrated in the first power assisting module; the first power assisting module comprises a liquid storage tank, a motor, a double-cavity series connection main cylinder, a servo cylinder, a pedal simulator and an ECU and further comprises a positive pressure booster, the positive pressure booster is provided with a servo cavity and a piston cavity which are isolated from each other, and a piston in the servo cavity is axially connected with a piston in the double-cavity series connection main cylinder in series. A first one-way valve is arranged on a pipeline between the piston cavity and the servo cavity, a piston in the servo cavity is connected with a brake pedal through a ball head push rod, and the servo cavity is connected with an air suspension module through a pipeline. And a gas conveying pipeline in the air suspension module is connected with the servo cavity and the piston cavity through a first air valve and a second air valve respectively. According to the invention, the function redundancy backup problem of various brake system fault conditions can be solved.
