Method for diagnosing operating condition of separator coupling, involves comparing model rotational speed with actual speed to be measured of combustion engine in idling operation, and deriving operating state of separator coupling
The method involves operating an internal combustion engine (4) at an idle state. Model rotational speed of the engine in an idling operation is set. The model rotational speed is compared with actual speed to be measured of the engine in the idling operation, and an operating state of a separator c...

| description | The method involves operating an internal combustion engine (4) at an idle state. Model rotational speed of the engine in an idling operation is set. The model rotational speed is compared with actual speed to be measured of the engine in the idling operation, and an operating state of a separator coupling (15) is derived. A crankshaft moment is automatically adjusted by an idling regulation unit (25). A notification is output to a user i.e. driver, of a drive system (1) i.e. motor car (2), if a difference between the rotation speed and the actual speed exceeds a predetermined limit. An independent claim is also included for a diagnostic apparatus for diagnosing an operating condition of a separator coupling.
Die vorliegende Erfindung betrifft ein Verfahren zum Diagnostizieren eines Betriebszustands einer Trennkupplung (15), die mindestens zwei Antriebsvorrichtungen, insbesondere eine elektrische Maschine (5) und eine Brennkraftmaschine (4) in einem Antriebssystem (1), insbesondere eines Kraftfahrzeugs (2) miteinander koppelt, wobei die Brennkraftmaschine (4) im Leerlauf betrieben wird, dadurch gekennzeichnet, dass für die Brennkraftmaschine (4) im Leerlaufbetrieb eine Modelldrehzahl (60) gebildet und mit der Brennkraftmaschine (4) im Leerlaufbetrieb assoziiert wird und die Modelldrehzahl (60) mit einer zu messenden Istdrehzahl (40) der Brennkraftmaschine (4) im Leerlaufbetrieb verglichen und davon der Betriebszustand der Trennkupplung (15) abgeleitet wird. Ferner wird ein geeignetes System zur Durchführung des erfindungsgemäßen Verfahrens bereitgestellt. |
