1. A control device for controlling an emergency brake pressure of a vehicle, the control device comprising:
a pressure regulator configured to regulate a pilot pressure (VSD1) for regular operation, wherein the VSD1 is determined beforehand in dependence on a load condition of the vehicle, a deceleration, a velocity, and/or a coefficient of friction;
a setting unit configured to control a safety pilot pressure (SVSD) in the event of system malfunction,
a pressure converter that includes:
a pressure inlet for a pneumatic or hydraulic pressure supply,
at least one pressure inlet for at least one pilot pressure, and
a pressure outlet for an emergency brake pressure,
wherein the pressure converter is configured to control a supply pressure of the pressure supply from the pilot pressure (VSD1) or the safety pilot pressure (SVSD) and then to output the supply pressure as the emergency brake pressure,
wherein the control device is configured such that, in regular operation, only the VSD1 is supplied to the pressure converter to control the supply pressure, and, in the event of system malfunction, only the SVSD is supplied to the pressure converter to control the supply pressure, and
wherein it is ensured that the emergency brake pressure remains below a nominal pressure in the event of system malfunction.
