ABSTRACT:
In order to improve the shifting characteristics of an electrohydraulically controlled, automatically shifting transmission particularly during cornering and braking, the driving speed (v), the lateral acceleration (aq), and the time variation of the throttle valve position are sensed in addition to the throttle valve position (alpha) and the engine rotational speed (nmot). From the time variation of the throttle valve position, a signal can be derived for the prevention of an upshifting operation since a motor vehicle driver's foot moves away faster from the accelerator pedal when approaching a bend in the road than would be the case for the normal deceleration of the motor vehicle.
