Ein Beispiel für den Einsatz eines Fahrzeugdiagnosesystems gemäß einem Ausführungsbeispiel der Erfindung wird im Folgenden anhand der in der Figur 2 dargestellten einfachen elektrischen Schaltung 40 beschrieben.An example of the use of a vehicle diagnostic system according to an exemplary embodiment of the invention is described below with reference to that in FIG Figure 2 shown simple electrical circuit 40 described.

Die in der Figur 2 dargestellte elektrische Schaltung 40 umfasst eine Reihenschaltung aus einer Sicherung 42, einem Schalter 44, einem Relais 46 und einem Aktuator 48. Bei dem Aktuator 48 kann es sich beispielsweise um einen Fensterheber, einen Scheibenwischermotor, einen Bremsaktuator oder einen Aktuator einer Servolenkung handeln.The in the Figure 2 The electrical circuit 40 shown comprises a series circuit comprising a fuse 42, a switch 44, a relay 46 and an actuator 48. The actuator 48 can be, for example, a window regulator, a wiper motor, a brake actuator or an actuator of a power steering system.

Bei intakter Sicherung 42 und geschlossenem Schalter 44 wird der Aktuator 48 über die Sicherung 42 und das Relais 46 mit elektrischem Strom versorgt, so dass der Aktuator 48 aktiv ist.When the fuse 42 is intact and the switch 44 is closed, the actuator 48 is supplied with electrical current via the fuse 42 and the relay 46, so that the actuator 48 is active.

Wird das Fahrzeug 2 nun mit dem Symptom, dass der Aktuator 5 auch bei geschlossenem Schalter 44 nicht aktiv ist, zur Fahrzeugdiagnose gebracht, kann durch eine Wärmebilduntersuchung gemäß einem Ausführungsbeispiel der Erfindung festgestellt werden, ob die Temperatur der Sicherung 42 und des Relais 46 erhöht sind. Aus einer erhöhten Temperatur kann auf einen Stromfluss durch die jeweilige Komponente 42, 46 geschlossen werden, ohne dass hierfür in den Stromkreis eingegriffen werden muss, um den durch die Schaltung 40 fließenden elektrischen Strom direkt messen zu können.If the vehicle 2 is brought to the vehicle diagnosis with the symptom that the actuator 5 is not active even when the switch 44 is closed, a thermal image examination according to an exemplary embodiment of the invention can be used to determine whether the temperature of the fuse 42 and the relay 46 are increased , A current flow through the respective component 42, 46 can be inferred from an elevated temperature without having to intervene in the circuit in order to be able to directly measure the electrical current flowing through the circuit 40.

Auf diese Weise kann die Diagnose erheblich vereinfacht werden. Im Falle großer Ströme und/oder Spannungen können darüber hinaus die Gefahren, die mit dem Eingriff in solch einen Stromkreis verbunden sind, insbesondere Stromschlag und/oder Funkenflug, vermieden werden.In this way, the diagnosis can be considerably simplified. In the case of large currents and / or voltages, the dangers associated with the intervention in such a circuit, in particular electric shock and / or flying sparks, can also be avoided.
