Abstract
In a control unit for automatic transmissions of motor vehicles, shifting points of a transmission are determined from performance graphs. Through the use of an evaluation circuit, a driving style of a driver is recorded and taken into account in determining the shifting points of the transmission. An operating mode can be initiated by the driver, and during the operating mode, shifting points that are manually selected by the driver are stored permanently in memory for calling up the shifting points as desired.
