Embodiment Construction

[0073] figure 1 The tested internal combustion engine is shown in an example diagram with schematically different parts, which were investigated separately for the load problem study and which must satisfy the proposed top-level requirements with respect to each other as a whole. Therefore, design and test the cylinder head scheme, valve operation system, combustion system, cooling scheme, exhaust gas recirculation scheme and on-board system. This can be very extensive in terms of the required measured values ​​and the pilot state tests necessary for this. Traditionally, measurement sequences are designed to be very large, time-consuming and expensive. The tuning parameters that are currently directly accessible are used in DoE planning, such as air quality, SOI, etc. Coverage of the target range can only be achieved by laboriously restricting the input parameters, or the target space can only be covered to a limited extent. An internal combustion engine is preferably arra...

Abstract

The invention relates to the creation of an experimental plan and the performance of a series of measurements, comprising the determination of operating data of a drive device to be tested and belonging to a vehicle by means of an automated statistical experimental plan (DoE), wherein the experimental plan includes at least the following steps: identification of one or more target variables which the drive device has to meet during test operation, and narrowing relevant values to the one or more target variables, assignment of one or more actuating variables to the drive device with one or more target variables and automated creation of the experimental plan on the basis of at least two target variables to be met.

Description

technical field [0001] The invention relates to a method for creating a test plan and executing a measurement sequence, with the acquisition of operating data of a vehicle drive to be tested by means of an automated statistical test plan. The statistical test plan is also referred to as design of experiments, hereinafter referred to as DoE. Background technique [0002] A technical system is generally described by which influencing and disturbing parameters act on a product or process. This effect yields measured parameters, which characterize general properties. These measured parameters are then compared to target parameters. Such system relationships can be described, for example, by corresponding curves, for example by polyphase curves, operating curves, characteristic curves and the like. [0003] Methods for checking the properties of technical systems can in principle be distinguished by analytical methods in which theoretical derivations or calculations are carrie...
