Electronically controllable braking system having two fall-back levels

An electronically controllable braking system for a vehicle, comprising:

• a service brake sub-system including:
• a front axle service brake circuit with front axle service brakes,
• a rear axle service brake circuit with rear axle service brakes, and
• a service brake control module, wherein the service brake control module is configured to generate a service brake control signal in dependence upon a braking specification, wherein a front axle service brake pressure supplied to the front axle service brakes and a rear axle service brake pressure supplied to the rear axle service brakes are generated in dependence upon the service brake control signal under the electrical control of the service brake control module;
• and
• a redundancy brake sub-system including:
• a front axle redundancy brake circuit,
• a rear axle redundancy brake circuit, and
• a redundancy brake control module, wherein the redundancy brake control module is configured to generate a redundancy brake control signal in dependence upon a braking specification, wherein a front axle redundancy brake pressure supplied to the front axle service brakes and a rear axle redundancy brake pressure supplied to the rear axle service brakes are generated in dependence upon the redundancy brake control signal under the electrical control of the redundancy brake control module.
