摘要： The invention concerns a method of monitoring the gear-shift process in an automatic transmission. In order to be able to recognize fault conditions, the invention proposes in one embodiment that the actual change in transmission ratio is compared with a required change in transmission ratio. In another embodiment, the change in the difference in speed of rotation at the engaging shift element is examined. It is also provided to analyze the gradient of the difference in speed of rotation at the engaging shift element. A further possibility is to monitor the gradient of the transmission-input speed. In addition, the gradient of the speed at the transmission output can be monitored. As a result of the analysis, the transmission ratio is either retained or a predetermined safety condition brought about.

摘要： A process is disclosed for automatically co-ordinating the filling and feeding of hydraulically operated and hydraulically or electronically individually commanded shift elements. The filling and feed operation is divided into a rapid filling phase and a filling equalisation phase and uses as parameters at least one rapid filling period, a rapid filling pressure, a filling equalisation period and a filling equalisation pressure. To optimise these parameters, two of the four are pre-set and in the case of the other two, an optimal value is determined firstly for a first parameter to be optimised on the basis of a pre-determined time-dependent pressure curve in which a pressure increase phase follows the rapid filling phase and filling equalisation phase. To that end, based on an initial value which can be pre-determined in each case, the first parameter is gradually adjusted until a speed change occurs at or before the start of the pressure climb phase. The other parameter is determined as follows: the parameter is gradually adjusted when the first parameter is at its optimal value and on the basis of the appropriate pre-determinable initial value until such time as a speed change occurs before or at least approximately simultaneously with the start of the pressure increase phase.
