System zur Steuerung einer Servokupplung

摘要

The invention relates to a system for controlling a servo-clutch fitted between a vehicle engine and gearbox in which the gear ratios are changed by disengaging and engaging the clutch by means of the operation of an adjuster by a control unit. In a first embodiment of the invention, the control unit is essentially designed in such a way that the stationary states of the engine are detected and the adjuster may be operated in any manner in response to the detected state without changing the gear ratio. In a second embodiment, the control unit is designed in such a way that, during the engagement and/or disengagement of the servo-clutch, the current engagement and/or disengagement travel and a value representing the current clutch moment found from the instanteous moment of the vehicle engine and the detected alteration in time of the engine revolutions are detected. In both embodiments, the combination of the detected engagement and/or disengagement travel and the value representing the current clutch moment is stored to plot a characteristic.
