Claim 0:
1. 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 electronic control unit is configured to receive a redundant parking brake signal for redundant control of the rear axle and the further axle and, to provide the shut-off signal at the shut-off valve, and
