Abstract

A method for operating an assistance system for automated driving operation of a vehicle involves continuously determining an emergency trajectory along which the vehicle is brought to a standstill in a longitudinally and transversely controlled manner after activation of an emergency operation of the vehicle. In the event of an imminent or already initiated lane change of the vehicle from a starting lane to a target lane according to a determined standard trajectory, a decision is made as to whether the vehicle should be brought to a standstill in the starting lane or in the target lane when emergency operation is activated. This decision depends on the position of the vehicle on the standard trajectory. The vehicle is then brought to a standstill in the starting lane if an emergency trajectory is planned by means of which the vehicle is brought to a standstill in the starting lane within a predefined path length and/or within a predefined time period, and if in the process a predefined comfort value of a transverse acceleration acting on the vehicle is not exceeded and a predefined penetration depth of the vehicle into the target lane is not exceeded.
