1. A method for classifying a behavior of a pedestrian when crossing a roadway of a vehicle, the method comprising:
- reading in sensor signals, from surroundings sensors of the vehicle, to detect the pedestrian and at least one piece of surroundings information regarding surroundings of the pedestrian;
ascertaining at least one physical variable of a relationship between the pedestrian and the at least one piece of surroundings information;
classifying the behavior of the pedestrian using the at least one physical variable;
determining at least one possible trajectory of the pedestrian as a function of the behavior of the pedestrian classified in the classifying; and
providing an activation signal to activate at least one component of a passenger protection system of the vehicle as a function of the possible trajectory;
wherein the passenger protection system includes;
(i) an air-bag arrangement, and (ii) a pedestrian protection device having an automatic braking arrangement and an evasive maneuvering arrangement, andwherein the at least one component of the passenger protection system includes at least one of the automatic braking arrangement, the evasive maneuvering arrangement, and the air-bag arrangement.

Abstract
A method for classifying a behavior, of a pedestrian when crossing a roadway of a vehicle, includes reading in a sensor signal to detect the pedestrian and at least one piece of surroundings information regarding surroundings of the pedestrian. The sensor signal represents here a signal of at least one sensor of the vehicle. The method further includes ascertaining at least one physical variable of a correlation between the pedestrian and the at least one piece of surroundings information. Finally, the method includes classifying the behavior of the pedestrian using the at least one physical variable.
