Abstract

A device for outputting parameter values and a method of providing parameter values which pertain to the relative kinematic behavior of an object, in particular a first vehicle, and a target object, in particular a second vehicle, a conclusion is drawn based on the parameter values as to whether the object and the target object will probably collide. The method involves providing a sensor system on the object, the sensor system being provided for transmitting and receiving signals to determine measured values ri, vr,i for target object distance r and/or for relative radial velocity vr between the object and the target object, determining measured values ri, vr,i and analyzing measured values ri, vr,i thus determined and providing the parameter values based on the signals received by a receiver.
