Abstract

A device for keeping a vehicle in its lane, including a reference model, which obtains geometric data regarding the position of the vehicle in the lane as well as data relating to the course of the lane from a lane detection system, and from these calculates a setpoint variable for controlling the vehicle position. In order to allow for corners to be cut, the guiding behavior of the control system is modified in such a way when cornering that, in the event of a deviation of the path of motion of the vehicle from the setpoint path of motion in the direction of the inside of the curve, no or only low steering forces are applied to the steering system.
