Abstract
A method of determining and shifting to an optimal gear in a vehicle prior to entering a curve in a vehicle which comprises an automatic transmission. A curve speed limit is determined for an anticipated curve which is recognized by a navigation device, an anticipated road pattern and dependent on the vehicle and curve or road data, and a sportiness indicator (Ftyp). For each anticipated curve, an actual, optimal gear is determined, based on the determined curve speed limit and the sportiness indicator (FTyp) and, after determining the optimal gear, the method performs a check to determine whether or not the optimal gear deviates from the engaged gear (RGA_DEST). When a deviation is recognized and a driver reaction, which causes a deceleration of the vehicle and/or a reduction of the vehicle speed, is present, a down shift down to the actual, optimal gear occurs.
