Damit kann sich beispielsweise ein Entwicklungs-Ingenieur ein Profil zur Untersuchung des Verhaltens des Fahrzeugs in bestimmten Situationen gezielt zusammenstellen. Beispielsweise lässt sich hierdurch der Zeitraum für eine seriennahe Erprobung der Fahrzeuge vor deren Serienherstellung verkürzen und deren Zuverlässigkeit erhöhen.In order to For example, a development engineer can profile himself Investigation of the behavior of the vehicle in certain situations put together in a targeted manner. For example, this can be the period for one shorten near-series testing of the vehicles before their serial production and their reliability increase.
Bei einer Weiterbildung der Erfindung ist vorgesehen, dass die von der Betriebsdatenverarbeitungs-Vorrichtung verarbeiteten oder ausgewerteten Betriebsdaten als Folge der konkreten Benutzung des Fahrzeugs durch den Fahrer bzw. Fahrzeugnutzer entstehen. Bei der Fehlerdiagnose kann das Verhalten des Fahrers bei der Suche nach der Fehlerursache berücksichtigt werden.at a development of the invention, it is provided that the of the Operating data processing device processed or evaluated operating data as a result of the driver's actual use of the vehicle or vehicle users arise. In the case of fault diagnosis, the behavior can considered by the driver in the search for the cause of the error become.
Bei einer Ausgestaltung der Erfindung handelt es sich bei den von der Betriebsdatenverarbeitungs-Vorrichtung verarbeiteten oder ausgewerteten Betriebsdaten um Daten, die als Folge des Verhaltens des Fahrzeugs während seines Betriebs entstehen. Bei der Fehlerdiagnose kann das Verhalten des Fahrzeugs bei der Suche nach der Fehlerursache berücksichtigt werden.In one embodiment of the invention, the operating data processed or evaluated by the operating data processing device is data that has been generated as a result of the behavior of the vehicle during its operation.
