Method and device for preventing collision of vehicles
First Claim
1. A method for preventing collisions of vehicles, wherein the surroundings of a vehicle and 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) is derived representing whether or not the vehicle approaching an intersection has the right of way and a collision risk criterion (K) is 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, G, 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.
