The utility model relates to a parking device of a vehicle, in particular to a parking brake control device of a vehicle. The parking brake control device comprises a fixing support (1), a handbrake handle (2), a parking bracing wire (3) and a traction wire, wherein the handbrake handle (2) is rotationally connected with the fixing support (2), the traction wire is connected between the parking bracing wire (3) and the handbrake handle (2), the handbrake handle (2) pulls the parking bracing to park the vehicle by means of dragging the traction wire, a guiding mechanism is disposed on the fixing support (1), and the traction wire matches with the guiding mechanism in a rolling manner. In the technical scheme, parking operating force transmission efficiency of the integral control device can be effectively improved, further, handbrake operating force is reduced, and the parking brake control device is simple in integral structure.
