Electropneumatic brake control device for controlling a parking brake of a vehicle having a service brake and a parking brake, comprising a) an electromagnetic valve device which is controlled by an electronic control device and can be supplied with compressed air from a compressed air store (8, 10) via a store connector, b) a parking brake signal terminal for inputting parking brake signals which are output by way of an electric parking brake signal transmitter, c) a valve device which is controlled pneumatically by the electromagnetic valve device and boosts the air quantity, with an operating output which can be connected to a first output port for at least one spring brake cylinder, which operating output is vented in order to apply the at least one spring brake cylinder and is ventilated in order to release it, d) a control air line being provided between an outlet of the electromagnetic valve device and a pneumatic control input of the valve device which boosts the air quantity, characterised by e) a pneumatically controlled 2/2-way valve, with an inlet which can be connected or is connected to the control air line or to the operating output of the valve device which boosts the air quantity, an outlet which is connected to a pressure sink, and a pneumatic control port for a supply pressure of the service brake, f) the pneumatically controlled 2/2-way valve having two positions, a passage position which is set at a supply pressure of the service brake which is lower than a predefined pressure limit value and in which the inlet is connected to the outlet, and a shut-off position which is set at a supply pressure of the service brake which is higher than a predefined pressure limit value and in which the inlet is shut off with respect to the outlet. a) an electromagnetic valve device which is controlled by an electronic control device and can be supplied with compressed air from a compressed air store (8, 10) via a store connector, b) a parking brake signal terminal for inputting parking brake signals which are output by way of an electric parking brake signal transmitter, c) a valve device which is controlled pneumatically by the electromagnetic valve device and boosts the air quantity, with an operating output which can be connected to a first output port for at least one spring brake cylinder, which operating output is vented in order to apply the at least one spring brake cylinder and is ventilated in order to release it, d) a control air line being provided between an outlet of the electromagnetic valve device and a pneumatic control input of the valve device which boosts the air quantity, characterised by e) a pneumatically controlled 2/2-way valve, with an inlet which can be connected or is connected to the control air line or to the operating output of the valve device which boosts the air quantity, an outlet which is connected to a pressure sink, and a pneumatic control port for a supply pressure of the service brake, f) the pneumatically controlled 2/2-way valve having two positions, a passage position which is set at a supply pressure of the service brake which is lower than a predefined pressure limit value and in which the inlet is connected to the outlet, and a shut-off position which is set at a supply pressure of the service brake which is higher than a predefined pressure limit value and in which the inlet is shut off with respect to the outlet.
