    Abstract: Bei einem automatischen Getriebe (17), insbesondere bei einem stufenlosen Umschlingungsgetriebe eines Kraftfahrzeugs können Situationen auftreten, bei denen Vorgaben für eine Übersetzungsänderung nicht umgesetzt werden können. Der Grund liegt dabei in einer ungenügenden Versorgung eines Hydrauliksystems (47, 48, 49, 50, 51, 52, 53, 54) mit Hydraulikfluid. Es ist Aufgabe der Erfindung eine Steuerungseinrichtung vorzuschlagen, welche eine ausreichende Versorgung des Hydrauliksystems (47, 48, 49, 50, 51, 52, 53, 54) mit Hydraulikfluid in möglichst vielen Fahrsituationen des Kraftfahrzeugs ermöglicht. Erfindungsgemäß wird in Abhängigkeit einer Abweichung zwischen der Vorgabe der Änderung und der tatsächlichen Änderung oder einer Abweichung zwischen der Vorgabe und einer Änderungs-Kenngröße, welche eine maximal mögliche Änderung der Übersetzung des Getriebes (17) kennzeichnet, eine Mindestdrehzahl der Antriebsmaschine (11) eingestellt. Damit wird eine ausreichende Versorgung mit Hydraulikfluid gewährleistet.

    Abstract: The invention relates to a method for operating the drive device of a vehicle. The drive device of a motor vehicle that comprises an engine and a continuously variable automatic transmission for driving the driven wheels of a vehicle is usually operated in a normal mode in normal driving operation and in a brake-engaging mode if the slip acting upon at least one of the wheels exceeds a determined value. During the brake-engaging mode the transmission ratios may vary widely or the vehicle may run at a low engine torque but high drive speed, which is often disagreeable for the driver. The aim of the invention is to provide a method with which the driving comfort is improved. To this end, a normal transmission ratio is given in the normal mode as the desired value of the transmission ratio and the transmission ratio is reduced to an actual transmission ratio in the brake-engaging mode. The difference between the normal transmission ratio and the actual transmission ratio is detected as the differential ratio and a maximum desired drive speed is modified depending on the differential ratio.

    Abstract: The invention relates to a method for controlling the multiplication for a continuously variable transmission with electrohydraulic drive using a control loop having a linear PID controller with the specified multiplication of the variator iv_soll serving as a command variable, with the actual multiplication iv serving as a regulating variable, and with the multiplication changing speed serving as a correcting variable. According to the invention, the correcting variable supplied by the PID controller is limited to limiting values, said limiting values being determined by the design, for an upshift and downshift, whereby these limiting values can be calculated from the limits determined by construction and from the operating point-dependent limits determined by volume flow, and the intersection of both permissible intervals determined by construction and by volume flow is defined as a permissible multiplication changing speed range.

    Abstract: The control (1) may be used in particular to control an automatic vehicle gearbox. Depending upon the accelerator depression, the vehicle speed or other quantities measured, a setting signal STS is established by means of which the gear to be selected or the transmission ratio to be set is determined. The control (1) has a classification system (4) to which the quantities measured and parameters derived therefrom are supplied as input values and, on the basis of an assessment of the quantities measured and parameters, output variables are generated by means of which the current running state or load state of the vehicle and the driving conduct of the driver are taken into account according to given assignments. The control (1) contains an evaluation circuit (14) in which an action signal generated by a manual action by the driver is assessed and then one of the predetermined relations is altered by the transmission of an assessment signal EBS. Here it is possible to switch off partial functions of the control (1) or modify important stored parameters of partial functions without putting it completely out of action.
