ABSTRACT:
A control for a motor vehicle drive having an automatic transmission includes a circuit configuration for generating an output signal adapting shifting points to a load state of the motor vehicle from an evaluation of a power takeoff rpm of the transmission or of a variable equivalent to it. The circuit configuration ascertains a deviation between a calculated and a measured power takeoff rpm in successive time intervals and forms a correction term by multiplication with a factor. At least one characteristic curve memory stores shifting points of the transmission. The at least one characteristic curve memory receives the correction term as an output signal for adapting a characteristic curve to the load state. In a method for controlling a vehicle drive having an automatic transmission, shifting points or characteristic curves for shifting are varied as a function of driving parameters. A power takeoff rpm of the transmission or a variable equivalent to it is evaluated in successive time intervals to obtain an output signal. Characteristic curves for shifting are adapted to a prevailing load state with the output signal.
