What is claimed is: 1. A method for operating at least one supercharger of an internal combustion engine having a boost pressure regulator, an output signal of the boost pressure regulator generating an actuating signal for controlling an actuating element of the at least one supercharger, the method comprising: providing a pilot control of the actuating element, wherein the pilot control is determined as a function of one of an exhaust gas volume flow and an exhaust gas mass flow, and wherein the pilot control is corrected by the boost pressure regulator, wherein the actuating element controls a cross section of an opening of a bypass duct around the turbine of an exhaust gas turbocharger, and wherein the pilot control is configured to operate in such a way that the cross section of the opening of the bypass duct increases when one of the exhaust gas volume flow and the exhaust gas mass flow increases. 2. A method for operating at least one supercharger of an internal combustion engine having a turbine in an exhaust tract of the internal combustion engine and at least one compressor in an induction tract of the internal combustion engine, comprising: providing an actuatable actuating element; generating an actuating signal for the actuating element; determining at least one of an an exhaust gas volume flow and an exhaust gas mass flow; wherein the actuating signal is determined as a function of a variable that represents one of the exhaust gas volume flow and the exhaust gas mass flow; specifying a setpoint value for one of the exhaust gas volume flow and the exhaust gas mass flow; calculating a deviation between the setpoint value and an actual value for one of the exhaust gas volume flow and the exhaust gas mass flow; and determining the actuating signal based on the deviation. 3. A method for operating at least one supercharger of an internal combustion engine having a boost pressure regulator, an output signal of the boost pressure regulator generating an actuating signal for controlling an actuating element for an exhaust gas turbocharger, the method comprising: providing a pilot control of the actuating element, the pilot control signal being determined as a function of one of an exhaust gas volume flow and an exhaust gas mass flow such that a counter-coupling response of the supercharger is simulated, wherein the pilot control includes: specifying a setpoint value for one of the exhaust gas volume flow and the exhaust gas mass flow; calculating a difference between the setpoint value and an actual value for one of the exhaust gas volume flow and the exhaust gas mass flow, the difference yielding a deviation signal; and determining the actuating signal based on the deviation signal. 4. The method as recited in claim 3, wherein the setpoint value is specified as one of a fixed value and a function of an engine rotational speed and a setpoint boost pressure. 5. The method as recited in claim 4, further comprising: providing a boost pressure regulator that generates an output signal as a function of the setpoint boost pressure and an actual boost pressure. 6. The method as recited in claim 5, further comprising: generating a pilot control signal as a function of one of the exhaust gas volume flow and the exhaust gas mass flow, wherein: an output signal from the boost pressure regulator corrects the pilot control signal. 7. A method for operating at least one supercharger of an internal combustion engine having a turbine in an exhaust tract of the internal combustion engine and at least one compressor in an induction tract of the internal combustion engine, comprising: providing an actuatable actuating element; generating an actuating signal for the actuating element; and generating an activating signal for an auxiliary compressor as a function of one of an exhaust gas volume flow and an exhaust gas mass flow; wherein the actuating signal is a function of a variable that represents one of the exhaust gas volume flow and the exhaust gas mass flow. 8. The method as recited in claim 7, further comprising: activating the auxiliary compressor when an exhaust gas volume flow is less than a setpoint volume flow. 9. The method as recited in claim 7, further comprising: activating the auxiliary compressor when a setpoint boost pressure is greater than a base boost pressure. 10. The method as recited in claim 7, further comprising: switching off the auxiliary compressor when one of: the one of the exhaust gas volume flow and the exhaust gas mass flow one of reaches a setpoint value and exceeds the setpoint value by a predetermined value, and a setpoint boost pressure is less than a base boost pressure. 11. A device for operating at least one supercharger of an internal combustion engine, comprising: an electronic control unit that includes a boost pressure regulator, an output signal of the boost pressure regulator generating an actuating signal for controlling an actuating element of the at least one supercharger, wherein the electronic control unit includes a pilot control that determines the actuating signal as a function of one of an exhaust gas volume flow and an exhaust gas mass flow such that a counter-coupling response of the supercharger is simulated, and wherein the pilot control is corrected by the boost pressure regulator; and wherein means are provided for: specifying a setpoint value for one of the exhaust gas volume flow and the exhaust gas mass flow; calculating a difference between the setpoint value and an actual value for one of the exhaust gas volume flow and the exhaust gas mass flow, the difference yielding a deviation signal; and determining the actuating signal based on the deviation signal. 12. A device for operating at least one supercharger of an internal combustion engine, comprising: an electrical control unit configured to generate at least one actuating signal for controlling at least one actuating element of the supercharger, wherein the control unit determines the actuating signal as a function of a variable representing one of an exhaust gas volume flow and an exhaust gas mass flow; wherein, for the determination of actuating signal, the control unit: specifies a setpoint value for one of the exhaust gas volume flow and the exhaust gas mass flow; calculates a deviation between the setpoint value and an actual value for one of the exhaust gas volume flow and the exhaust gas mass flow; and determines the actuating signal based on the deviation.
