Claim 10:
11. A redundancy system for supplementing a brake system, which is electronic, for a vehicle, comprising:
a module for providing control signals, including electronic control signals and pneumatic control signals, for the brake system which has a supply source, including:
at least one pneumatic interface to be connected to a compressed-air source;
at least one electronic interface to transmit the electronic control signals to at least one processing unit for generating brake pressures;
wherein the module is configured to be provided with a supply by a second supply source, and wherein the at least one processing unit is configured to generate at least one brake pressure not in an electronically controlled manner,

wherein the redundancy system is configured to be operated instead of the electronic brake system,
wherein in a first operation level, the control of the brake system is performed in an electronically controlled manner by a footbrake module of the module, which generates the electronic control signals to cause pressure control modules of the module to generate the brake pressures,
wherein in a first fault situation, which is characterized by a failure of the supply source, electronic control of the brake system by the footbrake module is no longer possible and the at least one processing unit is no longer capable of processing electronic control signals because they are no longer provided with a supply by the supply source, wherein the at least one processing unit is capable, in a fall-back level, of generating the brake pressures from the pneumatic control signals, wherein the electronic control signals are provided in an electronically controlled manner, wherein the module is provided with the supply by the second supply source and can electronically provide the pneumatic control signals, so that in the fall-back level, electronic control of the brake system is realized, and thus for control functions, including ABS control, continue to be realized, and
wherein in a second fault situation, the second supply source has failed, as a result of which electronic control of the brake system is thus no longer possible, either by the footbrake module or by the module, wherein the footbrake module is configured to generate the pneumatic control signals which can be transmitted to the at least one processing unit or via the module to the at least one processing unit, and wherein the at least one processing unit generates the brake pressures from the pneumatic control signals.
