Method for operating a driver assistance system, and driver assistance system
First Claim
1. A method for operating a driver-assistance system for providing lateral guidance of a motor vehicle in a lane change from a current lane to a target lane in a traffic-lane split, the method comprising:
- sensing the traffic-lane split of the current lane in which the motor vehicle is located;
ascertaining a position of the motor vehicle in relation to the traffic-lane split;
ascertaining a trajectory for the lane change of the motor vehicle from the current lane to the target lane so that the lane change from the current lane to the target lane is carried out at a predefined point in time following the traffic-lane split; and
operating the driver-assistance system so that the lane change is carried out in accordance with the ascertained trajectory;
wherein the predefined point in time is the earliest possible point in time for a lane change from the current lane to the target lane following the traffic-lane split.

Abstract
A method for operating a driver-assistance system for the lateral guidance of a motor vehicle in a lane change from a current lane to a target lane in a traffic-lane split. Also provided is a driver-assistance system for the lateral guidance of a motor vehicle in a lane change from a current lane to a target lane in a traffic-lane split. The driver-assistance system encompasses a trajectory-ascertainment device, which is configured to ascertain a trajectory for the lane change of the motor vehicle from the current lane to the target lane so that the lane change from the current lane to the target lane is carried out at a predefined point in time following the traffic-lane split.
