- control systems are often used which regulate an operating variable of the internal combustion engine and / or the vehicle to a predetermined setpoint.
- An example of such control systems are idle speed regulators, by means of which the rotational speed is regulated to a predetermined target value when the internal combustion engine is idling.
- Other examples are control systems for regulating the air throughput through the internal combustion engine, the exhaust gas composition, the torque, etc.

- the target and actual size are compared in the comparator 22. The deviation between the target and actual size is considered
- each of the parts or only one or more parts are variable, both as a function of operating variables and in the sense of a switchover depending on the operating mode of the internal combustion engine.
- the controller 24 forms, depending on the control deviation ⁇ , at least one output signal ⁇ l, which influences at least one of the control variables of the internal combustion engine, by means of which the internal combustion engine causes a rapid change in torque.
- the second controller 25 also forms depending on
- L5 represents this control variable the air supply, so that the control signal ⁇ 2 controls an actuator, for example a throttle valve, to influence the air supply to the internal combustion engine.
- an actuator for example a throttle valve
- each portion of controller 24 or controller 25 forms a controller output
- the various components of the controller 24 and / or that of the controller 25 have parameters, for example gain factors, the value of which can be changed depending on the design, i. H. can be switched between at least two values or characteristic curves.
- a controller with a proportional, integral and differential component is generally used.
- the homogeneous mode in which the internal combustion engine is operated with a stoichiometric mixture, at least the proportional and differential components are duplicated.
- One controller 5 is used to adjust the ignition angle, another to adjust the filling (air supply).
- the engine torque can only be adjusted via the amount of fuel, not against the amount of air.
- 5 the dynamic behavior of the internal combustion engine therefore differs from that in homogeneous operation.
- the time of the torque-determining intervention with respect to the top dead center of the cylinder is different in these operating modes. This results in a different dead time for the controlled system.
- L0 can achieve a large change in torque much faster than in homogeneous operation.
- At least one parameter of controller 24 and / or 25 is switched in L5 depending on an operating mode signal between different values (individual values or characteristic curves). Depending on the current operating mode, this is generated in 30 and fed to the respective controller for switchover via line 32 or 34.
- the parameter values take into account the optimal adaptation of the controller to the changing route dynamics. In this respect, the idle governor is better adapted to the route dynamics using mode-dependent parameter sets.
- all parameter values are also functions of the control deviation.

- the controller 25 which represents the air fraction
- the controller 25 is activated for the slow portion in homogeneous operation.
- the controller 25 is activated or deactivated by setting its output signal to the value 0.
- FIG. 2 represents a program of the computer unit of the control unit 10.
- the flow chart shows special configurations of the controllers 24 and 25.
- the control deviation ⁇ is fed to the controllers as the deviation between the actual and the setpoint (actual and setpoint speed).
- An integrator 100, an amplifier stage 102 and a differential stage 104 are provided in the controller 24 for the fast intervention path, while in the preferred exemplary embodiment
- an amplifier stage 106 and a differential stage 108 are provided in the controller 25 for the slow path.
- a different embodiment of the controller is used, so that the control strategy shown represents only one preferred exemplary embodiment.
- the idle controller shown in FIG. 2 is better adapted to the path dynamics using mode-dependent parameter sets.
- the control deviation ⁇ is preferably calculated by subtracting the target speed TARGET from the actual engine speed ACTUAL.
- the output signal DMLLRI of the integral component 100 is formed by integrating the control deviation ⁇ over time in the integrator 100 and subsequent amplification (multiplication) in the amplifier stage 110.
