Electronically controllable braking system and method for controlling the electronically controllable braking system

A method for controlling an electronic brake system, the method comprising:

• detecting whether a braking specification can be implemented via at least one service brake circuit and under electrical control by the service-brake control module;
• generating a redundancy control pressure in the trailer control valve as a function of the braking specification which is electrically specified, wherein the redundancy control pressure is generated in a controlled manner by the trailer control module in the trailer control valve;
• and
• generating a service-brake brake pressure in the at least one service brake circuit and/or a trailer control pressure for outputting to the trailer as a function of the redundancy control pressure which is generated in the trailer control valve, if implementation of the braking specification via the at least one service brake circuit under electrical control by the service-brake control module is prevented, wherein the electronic brake system comprises:
• at least one service brake circuit with service brakes and a service-brake control module, wherein a service-brake brake pressure can be fed to the service brakes, and the service-brake control module is configured to generate a service-brake control signal as a function of a braking specification, wherein the service-brake brake pressure can be generated as a function of the service-brake control signal and specified to the service brakes, for the implementation of the braking specification via the at least one service brake circuit, under electrical control, and
• a trailer control valve with a trailer control module, wherein the trailer control module is configured to receive and process an electronically communicated braking specification and the trailer control valve is configured to generate and output, under the control of the trailer control module, a redundancy control pressure as a function of the electronically communicated braking specification,
• wherein if implementation of the braking specification, under electrical control by the service-brake control module, via the at least one service brake circuit is prevented:
• the service-brake brake pressure can be generated as a function of the redundancy control pressure generated in the trailer control valve, and can be applied to the service brakes of the at least one service brake circuit, for redundant implementation of the braking specification in the vehicle, and/or
• a trailer control pressure can be generated as a function of the redundancy control pressure generated in the trailer control valve, and can be output to a trailer for the redundant implementation of the braking specification in the trailer.

• the trailer control pressure can also be generated as a function of the redundancy control pressure generated in the trailer control valve and output to the trailer, and
