Der Autor beschreibt eine Softwarearchitektur zur Automatisierung von Windkanaltests für Fahrzeuge mit aktiven Aerodynamikkomponenten. Ziel ist es, die aufwändige manuelle Steuerung durch eine integrierte Lösung zu ersetzen, die eine effiziente, nachvollziehbare und weitgehend automatisierte Durchführung homologationsrelevanter Tests ermöglicht.

Abstract:

Wind Tunnels are complex and cost-intensive test facilities. Thus, increasing the test efficiency is an important aspect. At the same time, active aerodynamic elements gain importance for the efficiency of modern cars. For homologation, such active aero-components pose an extra level of test complexity as their control strategies, the relevant drive cycles and their aerodynamics in different positions must be considered for homologation-relevant data.

Often, active components have to be manually adjusted between test runs, which is a time-consuming process because the vehicle is not integrated into the test automation. Even if so, designing a test sequence stepping through the individual settings for each component of a vehicle is a tedious task in the test session. Thus, a sophisticated integration of the wind tunnel control system with a test management system, supporting the full homologation process is one aspect of a solution. The other is the integration of the vehicle’s active aero components as controllable assets into the control system.

We present an architecture of a comprehensive set of software modules, which enhance the capabilities of an automation system making highly automated homologation tests of active components possible with minimal manual actions during the test. This includes a fully traceable test process from the vehicle components to the results of each step within an automatically generated test run, during which the active components’ parameters are varied in such way, that all test requirements are satisfied. Finally, these results are transferred back to the test requirements, from which in combination with control characteristics and market-specific drive cycles the relevant homologation data of the active aero components can be obtained.
