The invention relates to a method for providing lane-keeping support in automobiles during the operation of a fully automatic driver assistance system designed for driver-independent vehicle guidance by means of a control unit which controls the actuatorics of a steering system during operation of this driver assistance system such that the vehicle is maintained within the driving lane, characterized in that, in the event of failure of the steering system, targeted braking interventions are performed in order to maintain the lateral guidance for the lane-keeping support of the vehicle by means of a braking system of the vehicle.

Method for lane-keeping support for automobiles

A method for operating a motor vehicle using a control unit during operation of a fully-automatic driver assistance system is designed to guide the vehicle independently of the driver. The control unit actuates a drive unit and/or a brake unit during operation of said driver assistance system such that the motor vehicle maintains a predefined distance to a vehicle in front which is detected as a target object, the control unit also actuating the actuation unit of a steering system such that the motor vehicle is kept within its own detected lane. If the vehicle in front, detected as the target object, leaves the detected lane and if there is no new preceding vehicle, a braking action is performed.
