Claim:
1. A method for determining an emergency braking situation of a vehicle, the method of comprising: determining state variables including at least two of (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 using at least one control unit to: automatically determine, as a function of at least one of the determined state variables, to use one of at least two different methods to assess whether an emergency braking situation exists for the first vehicle, the at least two different methods including (a) an equation of motion assessment method by which an equation of motion system of the first vehicle and of the object ahead is determined and (b) a braking distance assessment method by which a braking distance of the first vehicle is determined; effect the one of the at least two different methods to assess whether an emergency braking situation exists for the first vehicle; and at least one of effect an emergency braking process and output a warning signal when an emergency braking situation exists based on a result of the assessment.
