Method for Determining an Emergency Braking Situation of a Vehicle
First Claim
1. A method for determining an emergency braking situation of a vehicle, the method comprising:
- determining state variables including at least (i) a speed of a first vehicle, (ii) a longitudinal acceleration of the first vehicle, (iii) a relative distance between the first vehicle and an object ahead, (iv) a speed of the object ahead, and (v) an acceleration of the object ahead; and
automatically determining as a function of the state variables which of at least two different methods for assessing whether an emergency braking situation exists for the first vehicle is used.

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.
