Abstract

A driving speed of a vehicle is limited when driving around a bend. A course of a curve of a route portion lying ahead of the vehicle is determined using a digital map. Depending on the course of the curve and on physical load limits of the vehicle, a course of a permissible bend speed is determined. The vehicle is controlled such that the determined permissible bend speeds are not exceeded when driving around the bend. By evaluating the course of the curve, a route portion, in which the curve is greater than a pre-determined curve limit value, is identified as a bend portion. Local curve maxima are identified in the identified bend portion. A permissible bend speed is determined for each local curve maximum depending on the curve and on a permissible lateral acceleration.
