Problems solved by technology

[0004] In general, it is disadvantageous to provide for the pre-production of all measuring points for the measurement in question, since these cannot reliably avoid unanticipated occurrences that compromise the operating state of the system

Embodiment Construction

[0025] figure 1 A schematic diagram of a test or inspection system 1 is shown, which is designed to measure a technical system 2 . The technical system 2 can be, for example, a combustion engine of a motor vehicle or a subsystem thereof. The measuring unit 3 controls the technical system 2 with a series of measuring points X which bring about a specific operating point of the technical system 2 . However, the measuring point X usually comprises a certain number d of input variables, which are combined in an input variable vector and thus forms a measuring point x. Furthermore, a permissible value range applies for each of the d input variables. Furthermore, actuation of the technical system 2 results in one or more output variables y, which are measured at the measuring point X.

[0026] Usually, in order to measure the technical system 2 completely, the measuring point X is varied within a relatively large range within the permissible value range, so that a space-filling...

Abstract

The invention relates to a method for measuring a technical system, especially a combustion engine for a motor vehicle, using a number of measuring points to in each instance obtain a value of at least one output variable. The method includes selecting a measuring point from a quantity of measuring points, determining a confidence value for the selected measuring point on the basis of a classification model, the confidence value indicating a permissibility of an operating point that results owing to the operation of the technical system at the measuring point, measuring the technical system at the selected measuring point as a function of the confidence value, and updating the classification model, with an indication as to whether the operating point of the technical system set by the measurement of the selected measuring point is permissible.

Description

technical field [0001] The invention relates to a test method and in particular a method for providing measuring points with which a technical system to be tested can be tested. The invention particularly relates to a method for providing measurement points within system limits. Background technique [0002] When measuring a technical system with measuring points, it is necessary to position the measuring points in such a way that as many as possible of the values ​​of the input variables are measured in combinations of different excitation modes, for example gradients of the input variables. Combination to obtain spatial and dynamic (raum- und dynamikfüllende) occupancy of the input data space with the measuring points. The values ​​of the output variable that are obtained for the measurement points during the measurement process can be used as training data for constructing a data-based non-parametric functional model. [0003] For technical systems to be modeled, such a...
