Method for monitoring and signaling a traffic situation in the surroundings of a vehicle
First Claim
1. A driver assistance system for monitoring and signaling a traffic situation in a surrounding environment of a vehicle, comprising:
- two or more sensor systems to acquire a surrounding environment of a vehicle;
a recognizing component to recognize objects in the acquired environment;
a reliability determining component to determine a prediction reliability concerning an object recognized in the environment;
a probability determining component to determine a probability of collision of the recognized object with the vehicle; and
an action component to carry out an action of a first type when there is a given collision probability and a low prediction reliability, and to carry out an action of a second type when there is the given collision probability and a high prediction reliability, wherein after carrying out the action of the first type, when there is the given collision probability and the high prediction reliability, the an action of the second type is carried out, and wherein the high prediction reliability is determined when the object is recognized via each of a plurality of the sensor systems and determined to have the given collision probability.

Abstract
A method for monitoring and signaling a traffic situation in the surrounding environment of a vehicle, a sensor acquiring a surrounding environment of the vehicle, an object at risk being recognized in the acquired environment, a collision probability and a prediction reliability being determined for the recognized object at risk, and when there is a given collision probability and a low prediction reliability an action of a first type being carried out, and when there is a given collision probability and a high prediction reliability an action of a second type being carried out. The present invention further relates to a driver assistance system for carrying out the method.
