Patent ID: 7077103

Claim:
A method for regulating the filling of an internal combustion engine, comprising: supplying a combustion air mass flow to a combustion chamber; arranging a first and second actuator, that are controlled with respect to their position, in the flow path of the combustion air mass flow, the second actuator being arranged downstream of the first actuator and the first and second actuators having an upper limit position that is open and a lower limit position that is closed; detecting an actual rotational speed of the internal combustion engine; and predefining a setpoint intake pipe pressure for controlling the first actuator, wherein as long as the second actuator is not in the lower limit position the setpoint intake pipe pressure is determined by a rotational speed-dependent characteristic map where the setpoint air mass flow is not an input parameter, and if the second actuator has reached the upper limit position for the current setpoint air mass flow, the setpoint intake pipe pressure is limited to an intake pipe pressure minimum value.
