Title: Process for evaluating the driving dynamic request of the driver for the driving strategy of an automatic/automated transmission

Abstract: The invention concerns a process for evaluating a driving dynamic request of a driver for the driving strategy of one of an automatic or automated transmission of a motor vehicle. It is proposed to calculate an accelerator pedal stroke, from the accelerator pedal actuation, which is supplied to the driving strategy as an input parameter to the driving strategy equivalent to the driving dynamic request. To this end, a rough value of the accelerator pedal stroke is calculated, especially by subtraction of the accelerator pedal position at beginning of the accelerator pedal movement from the accelerator pedal position, from accelerator pedal values which are in fixed event-dependent ratio to each other. The accelerator pedal stroke results from an event-dependent filtering of the rough value of the accelerator pedal stroke during which a filtering function starts at the end of the accelerator pedal movement, especially when the accelerator pedal position is constant over a presettable time. The rough value of the accelerator pedal, existing at this moment, breaks down by a presettable time function.
