    • A process and a device for air proportioning during idling or overrun mode of operation in an internal-combustion engine are provided. During idling, the internal-combustion engine is regulated to a nominal speed by means of a PI controller (203, 204) and a preliminary air rate control value is determined as a function of temperature, gear position and air-conditioning state of the vehicle. At the same time, the actual air mass or air intake rate (60) is measured and the difference value of the actual air intake rate and the preliminary air-rate control value is stored in a store (304). During overrun, the air-mass throughput of the internal-combustion engine is regulated to this stored value. Furthermore, the control receives a series of auxiliary variables which make it easier to carry out the control as a function of the particular operating mode.

    • The speed to be measured, either engine speed or vehicle (drive wheel) speed, is measured by a tachogenerator which trips a timer to provide a series of measurements. When the system is in use, a driver can store the actual speed at a selected moment as the desired speed. From a linearized model of vehicle speed or engine speed response to acceleration or deceleration of the engine by displacement of a control member, system parameters a.sub.1 and b.sub.1 are derived. The actual speed signal is multiplied by a.sub.1 and added algebraically (to produce a difference signal) to the desired speed signal, with the resulting signal then being multiplied by another constant derived from the system parameter b.sub.1 by reference to weighting factors p and q of a cost minimizing equation relating to the relative significance of obtaining a small control deviation and of limiting or increasing the amplitude of the control signal. An output signal is then provided by the second multiplying stage. The system can be constituted in an analog fashion or it may operate digitally by means of a microprocessor. Smoothing of the input and output signals may be provided by low-pass filtering in the analog case and by providing a moving average with the preceding value in the digital case. This type of regulation, which may be referred to as cyclic or as single-step control, assures an aperiodic run-in characteristic and is stable in all speed ranges.

    • A method and an arrangement for open-loop control and/or closed-loop control of an operating variable of an internal combustion engine is suggested with a transfer element fixing the relationship between input and output variables in the form of a characteristic curve or characteristic field such as an electrically actuable actuator, which directly or indirectly influences the operating variable of the engine of a motor vehicle and which fixes the relationship between the driving and operating variable or a variable influencing this operating variable in the form of a characteristic curve or a characteristic field. The transfer element or the characteristic curve or the characteristic field is subjected to changes. By adapting the characteristic curve or the computation instruction representing the characteristic curve or the characteristic field, these are adapted to these changes. This adaptation is performed in such a manner that at least one region of the characteristic curve or of the characteristic field is rotated about a pregiven point which lies outside of the characteristic curve and is specific to the actuator or to the engine. This point is adaptable in the context of a long-term adaptation.
