  • Patent number: 5293852
    Abstract: 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.
