  • a development typically has the development stages "MIL” or “model in the loop”, “SIL” or “software in the loop”, “VPIL” or “virtual platform in the loop” Hardware is running and the target system is emulated and "HIL” or "hardware in the loop” that is a software that runs on an information / communication technology hardware and controls an existing prototype.
  • V-Modell represents today's development standard for IT systems and is usually the basis for interdisciplinary system development.
  • On the left-hand side of the V-model there is an ever-more detailed analysis and design of systems into components, and finally the implementation of the software and the production of prototypes.
  • On the right side of the V-model on the other hand, starting from the component level up to the system level, further integration steps and further tests until finally the acceptance test of the entire system.
  • the development of complex hardware / software is increasingly becoming an ispecialized task that must combine mechatronics, electronics and software into a functional unit. This is tedious, expensive and makes the individual disciplines interdependent. Components can usually only be tested if the entire system is available. With correspondingly high costs for the prototypes.
  • the problem underlying the invention is to specify a method for the computer-assisted development of an overall system consisting of subsystems in such a way that the abovementioned disadvantages are avoided as far as possible and development can be carried out faster, more distributed, more reliably and more systematically.
  • the invention relates generally to a method for the computer-assisted development of an overall system consisting of subsystems, in which a combination of real products and real-time simulated virtual behavior models is used in the phases of the right branch of the V model, wherein the development stages "MIL", “ SIL “,” VPIL “each have an environment model, a reusable multiphysics model and a software and the development stage” HIL "next to the environment model still has a residual physics unit for the simulation of only virtually existing parts of the hardware of a product.

Abstract

Pour l'essentiel, l'invention concerne un procédé assisté par ordinateur permettant de développer un système global composé de systèmes partiels, selon lequel une combinaison de produits réels et de modèles de comportements virtuels simulés en temps réel est utilisée dans les phases de la branche droite du modèle V, les niveaux de développement « MIL », « SIL » et « VPIL » comprenant chacun un modèle d'environnement, un modèle multiphysique réutilisable et un logiciel, et le niveau de développement « HIL » comprenant, en plus du modèle d'environnement, une unité de physique résiduelle permettant de simuler les parties virtuellement disponibles du matériel d'un produit. Il est possible ainsi de réaliser une intégration temporellement parallèle et spatialement répartie ainsi qu'un test correspondant des composants à différents niveaux, autrement dit la branche droite d'un modèle V, qui peut se dérouler dans une large mesure du côté du concepteur du système. Il est possible ainsi de concevoir des fonctions de commande et de régulation ou des processus pour le niveau système global alors que tous les sous-systèmes ne sont pas encore disponibles. Il est inutile d'avoir des installations parallèles sur lesquelles de nouveaux processus ont été déployés au préalable. Par exemple, les systèmes critiques pour la sécurité peuvent tous être testés en laboratoire avant d'effectuer un test sur le véritable système global dans son véritable environnement. Certains composants essentiels du procédé de développement de l'invention, p. ex. des modèles multiphysiques en temps réel de la simulation et des tests système automatiques du niveau de développement « HIL », offrent l'avantage d'être réutilisables.
