Abstract

The invention relates to a method for detecting cornering for a vehicle (2) with automatic transmission. According to the invention it is proposed that the current bend radius be determined from the rotational speed signals of the front wheels, that the beginning of a cornering mode be determined when the current bend radius falls below a first limit bend radius and the end of a cornering mode be determined when the vehicle has covered a presettable distance after exceeding a second limit bend radius.
