A utility vehicle control device for a parking brake device of a trailer vehicle includes a pneumatic supply connection, a control connection for controlling a spring brake cylinder, a directly manually actuatable parking valve, a first connection line and a control valve for controlling the parking valve. The parking valve is arranged in the first connection line, and wherein as a result of the parking valve, the supply connection and the control connection can be connected via the first connection line. A control line branches from the first connection line. The control line is connected to a first pneumatic control input of the control valve, wherein the control valve has a second pneumatic control input. In the event of an unexpected reduction in operating pressure in the first connection line and/or in the control line, the control valve can be controlled by the first or second control input of the control valve such that a switching state of the parking valve can be pneumatically controlled by the control valve independently of an operating state of the supply connection, whereby the control connection is ventilated by the parking valve.
