Abstract

To determine whether an emergency braking situation exists for a vehicle, the vehicle determines at least the following state variables: its own velocity, its own longitudinal acceleration, its relative distance from an object in front, and the speed and acceleration of the object in front. A suitable evaluation method to assess whether an emergency braking situation is present is determined as a function of these state variables from a plurality of evaluation method options, including at least a movement equation evaluation method in which a movement equation system of the vehicle and of the object in front is determined, and an evaluation method in which a braking distance of the vehicle is determined.
