  "textContent": "An electropneumatic parking brake module includes 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, and an inlet-outlet valve unit configured to assume at least a first switching position and a second switching position. The parking brake module further includes an electropneumatic pilot control unit configured to output at least a first control pressure at the inlet-outlet valve unit. 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. The inlet-outlet valve unit is in the second switching position when the first control pressure is below a first threshold value.",
