Title: METHOD FOR THE OPEN-LOOP OR CLOSED-LOOP CONTROL OF A DRIVER ASSISTANCE SYSTEM OF A VEHICLE, AND DRIVER ASSISTANCE SYSTEM
Abstract:
The invention relates to a method for the open-loop or closed-loop control of a driver assistance system (14) of a vehicle (6), in which method at least one lane (2) and one road marking (8) of a road (1) are detected with the help of a first sensor device (16), which road marking separates the lane (2) from a road edge (10), and an actuation of at least one actuation device of the vehicle (6), said actuation device being used by the driver to influence the driving dynamics of the vehicle (6), is detected with the help of a second sensor device (20), the driving dynamics of the vehicle (6) being influenced by steering actuators and/or brake actuators, and in which method a first warning signal is issued if the first sensor device (16) detects that the vehicle is in danger of leaving the lane (2). According to the invention, if the driver does not respond to the first warning signal, the system waits until at least one wheel of the vehicle drives over the road marking. A second warning signal is then issued and, by means of automatic intervention in the steering, the vehicle is held on a target trajectory along the road marking that has already been driven over. If the driver does not respond to the second warning signal, the vehicle continues to be automatically held on the target trajectory along the road marking that has already been driven over and is automatically braked until it comes to a standstill.
