Abstract
For controlling an automatic transmission having an electronic control unit and having a power control element, the control unit detects a desired-power signal corresponding to the position of the power control element and, basically as a function of this desired-power signal, causes a change of gear corresponding to the characteristic shifting curves stored in the control unit. The control unit also generates a gradient signal corresponding to the rate of change of the desired-power signal and can—when certain conditions exist—cause a backshift deviating from the characteristic shifting curves as a function of this gradient signal. By way of the control unit, an immediate multiple backshift is initiated as a function of the gradient signal when, as a characteristic shifting curve for a first backshift has been reached, the gradient signal has exceeded at least a first lower limit value.
