Abstract: A method for ascertaining functional parameters for a control unit and to a control unit in which the provided method is carried out. The control unit is provided for controlling a technical system wherein, in the method, at least one target variable on a system response is specified and a variation of the functional parameters is carried out, from a response received to the functional parameters, a valuation being carried out of the set functional parameters while taking into account the at least one specified target variable.

Abstract: A method for operating an internal combustion engine for a motor vehicle, in which a first signal is determined, which characterizes a torque of the internal combustion engine. In order to provide a method for operating an internal combustion engine for a motor vehicle in which a torque of the internal combustion engine is determined even more precisely, in particular in the region of a zero crossing of the torque, a second signal, which characterizes a state variable of the internal combustion engine and/or the motor vehicle that differs from the torque is determined from the first signal, at least one third signal is recorded, which characterizes a measured value of the state variable, the second signal and the third signal are compared to one another, and the first signal is corrected on the basis of the comparison.

Abstract: A computer implemented method and control device for regulating a gasoline engine is provided. A control device automatically records a characteristic of Lambda values and loads a test phase during an operation of the gasoline engine having activated transition compensation. It automatically extracts relevant load changes as a function of the determined characteristics, a load change describing a change from a first load to a second load that differs from the first load. Further, the control device automatically implements a classification of the extracted load changes as a function of specifiable classification criteria and assigns at least one Lambda value to each of the load changes. The control device automatically determines a quality value for each of extracted load changes as a function of a deviation of the at least one assigned Lambda value from a specifiable setpoint Lambda value.

Abstract: To achieve a better compensation of the wall film effect in the operation of a gasoline engine as well as an objective evaluation of the quality of the transition compensation, the characteristic of Lambda values and a load are automatically detected in a test phase during an operation of the gasoline engine having activated transition compensation. Relevant load changes are automatically extracted as a function of the ascertained characteristics and classified as a function of specifiable criteria. For each load change extracted, at least one quality value is automatically determined as a function of a deviation of the at least one assigned Lambda value from at least one specifiable Lambda value. Each ascertained quality value is then weighted as a function of the implemented classification. Subsequently, an overall quality is calculated from the weighted quality values. At least one statistical method is used for this purpose.
