Claim 0:
1. An electropneumatic parking brake module, comprising:
a supply connection configured to connect a compressed air supply,
at least one spring-type actuator connection configured to connect at least one spring brake cylinder,
an inlet-outlet valve unit configured to assume at least a first switching position and a second switching position,
an electropneumatic pilot control unit configured to output at least a first control pressure at the inlet-outlet valve unit, and
a release control connection at which a release control pressure is configured to be output by an external unit to initiate the inlet-outlet valve unit to switch to the first switching position,
wherein, in the first switching position of the inlet-outlet valve unit, the spring-type actuator connection is connected to the supply connection for outputting a spring brake pressure, and, in the second switching position of the inlet-outlet valve unit, the spring-type actuator connection is connected to a venting connection of the inlet-outlet valve unit, and
wherein the inlet-outlet valve unit is in the second switching position when the first control pressure is below a first threshold value.
