Method and device for preventing collision of vehicles
First Claim
1. A method for preventing collisions of vehicles, in which on the one hand the surroundings of a vehicle and on the other motion parameters of the vehicle are detected by means of sensors, characterized in that from the output signals of the sensors (2.1, 2.2, 2.3, 2.4, 2.5), a failure- to-yield criterion (V) and a collision risk criterion (K) are derived;
- that from a combination of the failure-to-yield criterion and the collision risk criterion a risk level (A, B, C, D, E, F, G) is ascertained; and
that as a function of the particular risk level (A, B, C, D, E, F, G) ascertained, predetermined steps for reducing the collision risk are initiated.

Abstract
In a method for preventing collisions of vehicles, first the surroundings of a vehicle 2 and motion parameters of the vehicle 2 are detected by means of sensors 2.1, 2.2, 2.3, 2.4, 2.5. From the output signals of the sensors, a failure-to-yield criterion and a collision risk criterion are derived. From a combination of the failure-to-yield criterion and the collision risk criterion, a risk level is ascertained. Depending on the particular risk level ascertained, finally, steps for reducing the risk of collision are initiated.
