摘要：The invention relates to an electropneumatic brake controller (1) for
controlling a parking brake which includes at least one spring brake cylinder, comprisinga 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 workingoutlet (28) of which is connected to the connection (40) for the at least one spring brakecylinder; an electric parking brake signal connection (32) which is connected to theelectronic controller (14) for an electric parking brake signal generator (36) and via whichparking 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 airsupply, said supply connection being connected to the first solenoid valve device (8) andto a supply inlet (16) of the relay valve (18). According to the invention, the first solenoidvalve device (8) is made of three 2/2 way solenoid valves (10, 12, 30), each of which has ablocking 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 thesupply connection (2), a second 2/2 way solenoid valve (12) is connected between thecontrol inlet (20) of the relay valve (18) and a pressure sink (24), and a third 2/2 waysolenoid valve (30) is arranged between the working outlet (28) and the control inlet (20)of the relay valve (18).
