1. An actuating device for a fully or partially hydraulically acting brake system for a vehicle, comprising the following:
a master brake cylinder with a piston-cylinder unit which has a piston and a working chamber, wherein the working chamber is hydraulically connected or connectable to a reservoir and to a pedal feel simulator and is mechanically connected via an actuating unit that includes a brake pedal, and the working chamber is connectable via at least one valve, which is open when electrically deenergized, to at least one brake circuit,
at least one hydraulically acting wheel brake assigned to a brake circuit, and which is assigned in each case at least one dedicated controllable switching valve by means of which the wheel brake is connectable to the respective brake circuit for pressure build-up and pressure reduction,
a pressure supply which is driven by an electric motor and a piston of which is adjustable in a cylinder of the pressure supply by means of the electric motor,
at least one valve arrangement with solenoid valves for wheel-specific closed-loop pressure control,
at least one electrical control unit for controlling at least valves of the valve arrangement and the motor of the pressure supply, and
a superordinate control unit, distinct from the at least one electrical control unit,
wherein at least one electric parking brake and an electric drive motor are provided for driving at least one axle of the vehicle, wherein the electric parking brake and/or the electric drive motor transmit signals to and receive signals from the superordinate control unit, and
wherein a braking force of the parking brake and/or a torque of the electric drive motor is or are used for braking-force-imparted deceleration.
