An assistance system for supporting a driver of a vehicle when forming an emergency lane, wherein the assistance system is configured to:
- receive surroundings data, wherein the surroundings data describe lanes of a roadway and describe a position and a speed of further road users on the roadway;
- determine whether a predetermined emergency lane situation exists, in which the emergency lane is to be formed by the vehicle;
- determine a lane edge, to which the vehicle is to be moved to form the emergency lane;
- and
- carry out an automated lateral control of the vehicle to the lane edge if the predetermined emergency lane situation exists;
- determine a differential speed between the vehicle and at least one of the further road users on an adjacent lane based on the surroundings data;
- determine a lateral distance of the at least one of the further road users to a roadway marking of the adjacent lane based on the surroundings data;
- and
- carry out the automated lateral control depending on the differential speed or the lateral distance.
