Abstract

A method for operating a driver assistance function of a motor vehicle for maintaining a lane, including monitoring a lane on which the motor vehicle is moving, ascertaining a lane boundary of the lane, ascertaining a relative position of the motor vehicle with respect to the lane boundary, carrying out a control intervention in the motor vehicle as a function of a setpoint position of the motor vehicle relative to the lane boundary in order to keep the motor vehicle in the lane, ascertaining objects in the area of the lane, and adapting the control intervention as a function of the objects.

First claim

1 - 10 . (canceled)

11 . A method for operating a driver assistance function of a motor vehicle for maintaining a lane, comprising:
monitoring a lane on which the motor vehicle is moving; ascertaining a lane boundary of the lane; ascertaining a relative position of the motor vehicle with respect to the lane boundary; carrying out a control intervention in the motor vehicle as a function of a setpoint position of the motor vehicle relative to the lane boundary to keep the motor vehicle in the lane; ascertaining an object in the area of the lane; and adapting the control intervention as a function of the object.

12 . The method as recited in claim 11 , wherein the control intervention is reduced or prevented.

13 . The method as recited in claim 11 , wherein the setpoint position is adapted to the object.

14 . The method as recited in claim 11 , wherein a warning is output to the driver upon crossing the lane boundary, the warning taking place independently of the control intervention.

15 . The method as recited in claim 11 , wherein the control intervention is adapted only when a turn signal of the motor vehicle is deactivated.

16 . The method as recited in claim 11 , wherein the lane is monitored by at least one of a video sensor, a radar sensor, a LIDAR sensor, and an ultrasonic sensor.

17 . The method as recited in claim 11 , wherein the adaptation takes place as a function of a relative speed between the motor vehicle and the object.

18 . A control and evaluation unit for providing a driver assistance function for a motor vehicle for maintaining a lane, the control and evaluation unit designed to:
monitor a lane on which the motor vehicle is moving; ascertain a lane boundary of the lane; ascertain a relative position of the motor vehicle with respect to the lane boundary; carry out a control intervention in the motor vehicle as a function of a setpoint position of the motor vehicle relative to the lane boundary to keep the motor vehicle in the lane; ascertain an object in the area of the lane; and adapt the control intervention as a function of the objects.

19 . A non-transitory electronic storage medium on which is stored a computer program for operating a driver assistance function of a motor vehicle for maintaining a lane, the computer program, when executed by a computer, causing the computer to perform:
monitoring a lane on which the motor vehicle is moving; ascertaining a lane boundary of the lane; ascertaining a relative position of the motor vehicle with respect to the lane boundary; carrying out a control intervention in the motor vehicle as a function of a setpoint position of the motor vehicle relative to the lane boundary to keep the motor vehicle in the lane; ascertaining an object in the area of the lane; and adapting the control intervention as a function of the object.
