The invention relates to the technical field of automobile brake systems, in particular to an air dryer, an air brake control system and a vehicle, and the air dryer comprises a drying cylinder, an air inlet pipeline, a pressure release valve and a conducting two-position three-way valve. The other end of the air inlet pipeline is connected with the drying cylinder; the pressure release valve is connected with the air inlet pipeline and comprises a pressure release control port, and when the pressure of the pressure release valve is larger than first set pressure, the pressure release valve is switched on; the conducting two-position three-way valve comprises a conducting air inlet, a conducting air outlet, a conducting exhaust port and a conducting control port, the conducting air inlet is connected with the drying cylinder, the conducting air outlet is connected with the pressure relief control port, the conducting control port is connected with the parking pipeline, when parking is released, the conducting air outlet is communicated with the conducting exhaust port, and when parking is conducted, the conducting air outlet is communicated with the conducting exhaust port. And the conducting air inlet is communicated with the conducting air outlet, and the pressure release valve is communicated. The problems that in the prior art, air pressure of an air steel pipe is emptied in an electric control mode, faults are prone to occurring, and the maintenance cost is high can be solved.
