“…In particular, its introduction in the automotive sector has deeply changed the development and manufacturing processes. Thus, a car is no longer conceived as a mechanical device that carries some electronic controls, but as a mechatronic system [Bertram et al, 2003], where the components of different technologies are fully integrated [DesJardin, 1996].…”

International audienceWe propose in this paper an overall ten-step methodology dedicated to the analysis and quantification of reliability during the design phase of a mechatronic system, considered as a complex system. The ten steps of the methodology are detailed according to the downward side of the V-development cycle usually used for the design of complex systems. Two main phases of analysis are complementary and cover the ten steps, qualitative analysis and quantitative analysis. The qualitative phase proposes to analyze the functional and dysfunctional behavior of the system and then determine its different failure modes and degradation states, based on external and internal functional analysis, organic and physical implementation, and dependencies between components, with consideration of customer specifications and mission profile. The quantitative phase is used to calculate the reliability of the system and its components, based on the qualitative behavior patterns, and considering data gathering and processing and reliability targets. Systemic approach is used to calculate the reliability of the system taking into account: the different technologies of a mechatronic system (mechanics, electronics, electrical ...), dependencies and interactions between components and external influencing factors. To validate the methodology, the ten steps are applied to an industrial system, the smart actuator of Pack'Aero Company

“…The most appropriate methods for modeling of mechatronic systems are state-transition models such as state graphs (Markov graphs, Bayesian networks) and approaches based on Petri nets [Bertram et al 2003]. Petri nets can be used for modeling the functioning and non-functioning states of complex systems [Charki et al 2009].…”

“…The integrated nature of the HIL system also allows automated tests to be carried out. Automated testing of ECU software is a technology that has been implemented by automotive manufacturers over that last few years [10,11,12,13]. The general bene ts of such an approach to testing are: The approach described in this paper is developed to make use of an automated testing process linked directly to ECU speci cation data.…”

The purpose of this paper is to present an approach to testing ECU diagnostic software using hardware-in-the-loop (HIL) systems at Jaguar Land Rover (JLR). The increasing complexity of embedded software for automotive electronic control units (ECUs) requires a convenient and exible environment for system testing. On-board diagnostic software represents a signi cant proportion of ECU software and consequently, the effort, in terms of time and manpower required to determine the validity of ECU software is becoming excessive. The process for validating on-board diagnostic software is traditionally achieved using tests carried out with actual vehicles. Some tests are dif cult and expensive to perform in vehicles. Automated testing offers an approach that can improve the validation process whilst providing the potential for cost saves. Since JLR utilises ECUs from different suppliers, the development of a generic approach to automated testing is vital.

Zur Verbesserung der Sicherheit im Straßenverkehr werden in Zukunft zunehmend Fahrerassistenzsysteme zur Unterstützung des Fahrers bei der Fahrzeugführung eingesetzt. Insbesondere werden für kritische Situationen Notfalltrajektorien benötigt, deren Planung mit Hilfe der Theorie der elastischen Bänder vorgenommen werden kann. Die zugehörige Ausweichbahn legt sich dabeiähnlich einem physikalischen elastischen Band um das Hindernis. Sowohl die innere Kontraktion als auch die externe Repulsion der Hindernisse werden mit Hilfe von Federpotenzialen realisiert. Lokaleäußere Einflüsse auf das Band wirken sich global aus, so dass die Krümmungsänderungen minimiert und somit auch Gefahren für das Fahrzeug reduziert werden. Dabei werden die Trajektorien für Fahrmanöver, wie z.B. für einen Spurwechsel, und die zugehörige Ausweichbahn durch kubische Splines generiert. Die fahrdynamische Realisierbarkeit der generierten Notfalltrajektorie unter den gegebenen Randbedingungen, wie Fahrzeuggeschwindigkeit und Witterungsverhältnisse, wird mit Hilfe eines auf ein Fahrdynamikmodell angewandtes Least-Squares-Verfahren vorab sichergestellt. Das vorgestellte theoretische Verfahren ist Bestandteil eines deutsch-niederländischen Kooperationsprojektes und wird am Beispiel des Szenarios einer Kolonnenfahrt auf einer mehrspurigen Fahrbahn mit Ein-und Ausfädelvorgängen einzelner Fahrzeuge demonstriert.
