ABSTRACT:
A measured value (MAP_MES) of the pressure in a suction pipe is the command variable of a control loop. The regulating variable is an estimated value (MAP_EST) of the pressure in the suction pipe, the estimated value being determined according to the manipulated variable of the control loop. The manipulated variable is calculated according to the difference between the estimated value (MAP_EST) and a measured value (MAP_MES) of the pressure in the suction pipe and according to the temporal change of the measured value (MAP_MES) of the pressure in the suction pipe. An estimated value (MAF_EST) of the mass flow in the intake passage (1) is calculated according to the manipulated variable.
