The invention belongs to the technical field of parking braking, and particularly relates to a parking braking control device. According to the technical scheme, the parking braking control device comprises a main air channel used for being connected with a main air cylinder, a brake air channel used for being connected with a brake cylinder and a parking air channel used for being connected with a parking cylinder, a two-position three-way electromagnetic valve is connected to the main air channel, and an electric signal plate type cock is further connected to a parking pipeline. The two-position three-way electromagnetic valve and the electric signal plate type cock are both connected with an exhaust gas path; the device comprises a two-way valve which is connected with the main air path, the braking air path and the parking air path respectively; and further comprises a parking electric control device which is electrically connected with the two-position three-way electromagnetic valve and the electric signal plate type cock respectively. Provided is the parking brake control device that avoids excessive braking force by means of the two-way valve.
