An electropneumatic parking brake modulator for controlling a parking brake mode of trailer brakes in a vehicle/trailer combination includes a valve element for airing and bleeding the trailer spring brake cylinders, at least one compressed air reservoir inlet for airing at least one compressed air line in the parking brake modulator with compressed air from a compressed air reservoir of the towing vehicle, at least one compressed air reservoir outlet at which a reservoir pressure can be made available for the brakes of the trailer, and at least one compressed air control outlet at which a control pressure can be made available for the brakes of the trailer. A towing vehicle protection valve is integrated into the parking brake modulator, and a compressed air line to the compressed air control outlet is automatically blockable when the reservoir pressure made available for the trailer falls below a predetermined threshold value.
