Electropneumatic parking brake arrangement having a shut-off valve and method for controlling an electronically controlled pneumatic brake system

An electro-pneumatic parking brake arrangement for an electronically controlled pneumatic braking system, the electronically controlled pneumatic braking system having spring-loaded brakes at a rear axle and a further axle of a vehicle, the electro-pneumatic parking brake arrangement comprising:

• a shut-off valve;
• and
• a parking brake module comprising:
• a reservoir connection configured to connect to a compressed air reservoir,
• a first spring-loaded accumulator connection configured to connect to the shut-off valve,
• an electro-pneumatic valve unit having at least one electro-pneumatic valve configured to output a spring-loaded brake pressure at the first spring-loaded accumulator connection, and
• an electronic control unit configured to receive parking brake signals from an electronic parking brake switch and/or a higher-order control unit,
• wherein the shut-off valve comprises a second spring accumulator connection configured to connect the spring-loaded brakes of the further axle and to shut off the second spring accumulator connection depending on a shut-off signal provided by the parking brake module,
• wherein the shut-off valve has a first switch position, in which the spring-loaded brake pressure is configured to be passed through to the spring-loaded brakes of the further axle, and a second switch position, in which the spring-loaded brakes of the further axle remain ventilated regardless of the spring-loaded brake pressure,
• wherein the shut-off valve is configured to output, in the second switch position, a supply pressure at the spring-loaded brakes of the further axle, and
• wherein the electronic control unit is configured to provide the shut-off signal at the shut-off valve when a parking brake signal of the electronic parking brake switch for disengaging the parking brakes is received.
