Claim 0:
1. A hydraulic motor vehicle braking system, comprising:
a first functional unit having
at least one first valve arrangement, which is configured either to connect at least one first wheel brake, which is associated with a first axle, to a prevailing hydraulic pressure or to separate it therefrom;
at least one second valve arrangement, which is configured either to connect at least one second wheel brake, which is associated with a second axle, to a prevailing hydraulic pressure or to separate it therefrom;
at least one first electrical brake pressure generator, by means of which a brake pressure can be generated at each of the at least one first and the at least one second wheel brake; and
a first controller, which is configured to activate the at least one first electrical brake pressure generator for a brake pressure regulation;
a second functional unit downstream of the first functional unit having at least one second electrical brake pressure generator, by means of which a brake pressure can be generated at least at the at least one second wheel brake; and
a second controller, which is configured to activate the at least one second electrical brake pressure generator for a brake pressure regulation at least at the at least one second wheel brake in the event of a malfunction of the first functional unit; and

a switching device, which is configured to couple either the first controller or the second controller with the at least one first valve arrangement in dependence on an operability of the first functional unit.
