Process and device for the reduction of clutch-grabbing oscillations in a motor vehicle drive train
Abstract:
Process for reducing clutch-grabbing oscillations in a motor vehicle drive train having a drive motor, clutch and another drive train, in which process the moment transmitted by the clutch for the control of an actuator that operates an operating member of the clutch when oscillations occur is changed such that oscillations are diminished, where an electric voltage driving the actuator is modulated according to the formula: UM=UMSt*w+UMR*(1−w), whereby, w is a weighting factor which assumes a value between 0 and 1, UMst is a modulation voltage controlled in a defined manner by an actuator model and a required travel modulation and, UMR is a modulation voltage regulated by a control device, which voltage is a magnitude that characterizes an operating state of the clutch on the basis of deviation between a required value and the actual value.
