Abstract

A hydraulic motor vehicle braking system includes a first functional unit, a second functional unit and a switching device. The first functional unit comprises at least one first valve arrangement designed to optionally connect or disconnect at least one first wheel brake associated with a first axle to or from an existing hydraulic pressure, and at least one second valve arrangement designed to optionally connect or disconnect at least one second wheel brake associated with a second axle to or from an existing hydraulic pressure. The second functional unit comprises at least one second electrical brake pressure generator, by means of which a brake pressure can be generated on at least the at least one second wheel brake, and a second control system which is designed to control the at least one second electrical brake pressure generator for a brake pressure regulation on at least the at least one second wheel brake in the event of a failure of the first functional unit.
