The invention relates to an electropneumatic brake controller (1) for controlling a parking brake which includes at least one spring brake cylinder, comprising a connection (40) for the at least one spring brake cylinder; a first solenoid valve device (8) which can be controlled by means of an electronic controller (14); a relay valve (18), the pneumatic control inlet (20) of which is connected to the first solenoid valve device (8) and to the connection (40) for the at least one spring brake cylinder and the working outlet (28) of which is connected to the connection (40) for the at least one spring brake cylinder; an electric parking brake signal connection (32) which is connected to the electronic controller (14) for an electric parking brake signal generator (36) and via which parking brake signals can be transmitted into the controller (14); and a supply connection (2) which is secured by a non-return valve (4) for at least one compressed air supply, said supply connection being connected to the first solenoid valve device (8) and to a supply inlet (16) of the relay valve (18). According to the invention, the first solenoid valve device (8) is made of three 2/2 way solenoid valves (10, 12, 30), each of which has a blocking position and a passage position. A first 2/2 way solenoid valve (10), in the form of an inlet valve, is connected between the control inlet (20) of the relay valve (18) and the supply connection (2), a second 2/2 way solenoid valve (12) is connected between the control inlet (20) of the relay valve (18) and a pressure sink (24), and a third 2/2 way solenoid valve (30) is arranged between the working outlet (28) and the control inlet (20) of the relay valve (18).
