The momentary friction performance of a motor vehicle clutch is ascertained in a computer (25) in dependence upon the torque to be transmitted by the clutch (3) and the slip of the clutch. In several stores (37, 41, 45) mean friction performance values are accumulated which are corrected in time dependence but with different rate of variation by correction devices (39, 43, 47), in accordance with the temperature behaviour of the clutch (3) on the surfaces of the friction linings (15), the mean temperature behaviour of the fly-wheel (19) and of the presser plate (23) and the heat emission to the surroundings. Monitor devices (49, 51, 53) allocated to the stores (37, 41, 45) ensure the monitoring of these temperature conditions in dependence upon specifically pre-determined limit values. The arrangement thus permits a more exact and more rapidly responding temperature monitoring of the friction clutch. <IMAGE> |
