Abstract
An electropneumatic parking brake module () includes a supply connection (), a spring-type actuator connection (), an inlet-outlet valve unit () having a first switching position and a second switching position, and an electropneumatic pilot control unit () for outputting at least a first control pressure (p) at the inlet-outlet valve unit (). In the first switching position of the inlet-outlet valve unit (), a spring brake pressure (pF) can be fed through directly from the supply connection () to the spring-type actuator connection () by virtue of the fact that the spring-type actuator connection () is connected to the supply connection (), and, in the second switching position of the inlet-outlet valve unit (), when the first control pressure (p) is below a first threshold value, the spring-type actuator connection () is connected to a ventilating connection () of the inlet-outlet valve unit ().
