Pressure medium actuated vehicle braking system

Pressure medium actuated braking system, comprising:

• a braking power imparting device,
• at least first and second braking circuits,
• said first braking circuit comprising a first pressure medium storage container, at least a first braking cylinder, and a first control valve system which connects said first braking cylinder of said first braking circuit to said first pressure medium storage container or to a pressure medium sink in dependence on a first control signal produced by said braking power imparting device,
• said second braking circuit comprising a second pressure medium storage container, first and second braking cylinders, and a second control valve system which connects said first and second braking cylinders of said second braking circuit to said second pressure medium storage container or to a pressure medium sink in dependence on a second control signal produced by said braking power imparting device,
• said second control valve system further comprising a pressure medium input connected to said second pressure medium storage container, and a pressure medium output connected to said first and second brake cylinders of said second braking circuit, and an additional control valve system disposed between said pressure medium output of said second control valve system and said first braking cylinder of said second braking circuit, said additional control valve system connecting said first braking cylinder of said second braking circuit to a third pressure medium storage container which is independent of said second pressure medium storage container as a function of a control signal assigned to a braking circuit other than said second control signal assigned to said second braking circuit.
