Abstract: A method of operating a drive-train of a vehicle that comprises a combustion engine whose torque for driving the vehicle can be transmitted to a drive output via a transmission, with a hydraulically actuated clutch when the clutch is engaged. An electric machine provides torque which can act upon the drive-train. The clutch is closed by filling the clutch with hydraulic fluid through a circuit by way of a pump which can be driven by the engine and the electric machine. The method is to engage the clutch when the combustion engine is initially off and/or when the electric machine is initially switched off, determining a driving dynamic based on the behavior of the driver and adjusting the speed of the electric machine based on the determined driving dynamic such that the greater the determined driving dynamic is, the more rapidly the clutch is filled by the pump.

Abstract: A method of operating a clutch serving as a shift element and/or starting clutch of a drive train. During engagement, the clutch will be filled by a fast filling up to a defined minimum pressure. The fast filling is at least subdivided into two phases comprising a basic filling phase and an extension and/or a cutout phase. At the end of the basic filling phase, the actual clutch pressure is measured, and then, when the actual clutch pressure is equal to or larger than the minimum pressure, the extension and/or cutout phase is activated immediately following the basic filling phase. When the actual clutch pressure is lower than the minimum pressure, activation of the extension and/or the cutout phase is at least delayed by a pressure holding phase and, if necessary, by a pressure surplus phase.

Abstract: A method of adapting the rapid filling time of a clutch. During adaptation, the clutch is filled by at least two successive rapid filling pulses with increasing rapid filling times. For each rapid filling pulse a reaction, resulting from the filling pulse, is monitored. If a defined reaction, for one of the rapid filling pulses, is recognized for the first time whereas for the, or for each of the previous rapid filling pulse(s) the defined reaction was not observed, then as a function of the rapid filling time of that rapid filling pulse for which the defined reaction was recognized for the first time, carrying out the adaptation of the rapid filling time and, for each rapid filling pulse used for the adaptation, gradients of the clutch pressure produced as a result of the respective rapid filling pulse are evaluated to determine the defined reaction pressure.

Abstract: In a method for representing a plurality of at least partially overlapping objects on a display device having a pixel matrix, wherein a distance value is associated with every object as a measure for a virtual distance to a viewer and the pixels of every object can be associated with an object region, a region priority value is associated with every object region. An object to be represented with a halo is subdivided into the object regions object core and the surrounding halo, the pixels of an object core being associated with a higher region priority value than the pixels of a halo. The pixels of an object without halo are associated with the object region ‘object surface’ with a lower region priority value than the pixels of a halo. In a preceding process step, the object region of the halo is initially treated and the object region of the object core is processed and displayed in a subsequent process step.
