An electropneumatic brake control device controls a parking brake of a vehicle with a service brake and the parking brake. It includes an electromagnetic valve device which can be supplied with compressed air from a compressed air storage via a storage connection; a parking brake signal connection for inputting parking brake signals output by an electric parking brake signaling device; and an air quantity-boosting valve device which is pneumatically controlled by the electromagnetic valve device and which has a working outlet that can be connected to a first outlet connection for at least one spring applied brake cylinder. A control air line is provided between an outlet of the electromagnetic valve device and a pneumatic control inlet of the air quantity-boosting valve device. A pneumatically controlled 2/2-way valve has an inlet which can be connected to the control air line or the working outlet of the air quantity-boosting valve device, an outlet which is connected to a pressure sink, and a pneumatic control connection for a stored pressure of the service brake. The pneumatically controlled 2/2-way valve has two positions: a conducting position, which is smaller than a specified threshold value in the event of a stored pressure of the service brake and in which the inlet is connected to the outlet, and a blocking position, which is larger than a specified pressure threshold in the event of a stored pressure of the service brake and in which the inlet is blocked from the outlet.
