The invention relates to a method for determining the disc temperature of a multi-disc clutch over time, said multi-disc clutch being used in the drive train of a motor vehicle and having clutch discs that are located in a housing and rotate in oil. The method comprises the following steps: setting of a first disc temperature (TLam,0); measurement of a reference temperature (TRef,i) of a medium or component, which exchanges heat at least indirectly with the clutch discs, at time intervals (i = 0, 1, 2, ...); determination of the frictional power (Pi) that is exerted on the multi-disc clutch at the same time intervals (i = 0, 1, 2, ...); and calculation of the subsequent disc temperatures (TLam,i) at the same time intervals (i = 1, 2, ...) from the respective preceding disc temperature (TLam,i-1), the measured reference temperatures (TRef,i) and the determined frictional powers (Pi). |
