Patent ID: 7145441

Claim:
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.
