1. A method for classifying surroundings of a motor vehicle into one of multiple predefined classes, comprising:
- providing, by an estimating unit, a classification regarding one of multiple predefined classes to which the surroundings belong, the multiple predefined classes including at least two of a freeway class, a traffic-calm zone class, a city traffic zone class, or a parking situation class;
receiving, via an interface unit, sampled pieces of information from the surroundings of the motor vehicle;
determining, by a processing unit, based on the sampled pieces of information, at least one criterion which supports or weakens the classification;
storing a plurality of determined criteria; and
determining, by the processing unit, a probability of the classification being correct with the aid of Bayes filtering of the at least one criterion, the probability being determined based on the stored criteria.

Abstract
A method for classifying surroundings of a motor vehicle includes: providing a hypothesis regarding the class to which the surroundings belong; sampling pieces of information from the surroundings of the motor vehicle; determining a criterion which supports or weakens the hypothesis based on the sampled pieces of information; and determining a probability of the hypothesis being correct, using the criterion with the aid of Bayesian filtering.

14. A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for classifying surroundings of a motor vehicle into one of multiple predefined classes, the method comprising:
-
providing, by an estimating unit, a classification regarding one of multiple predefined classes to which the surroundings belong, the multiple predefined classes including at least two of a freeway class, a traffic-calm zone class, a city traffic zone class, or a parking situation class; receiving, via an interface unit, sampled pieces of information from the surroundings of the motor vehicle; determining, by a processing unit, based on the sampled pieces of information, at least one criterion which supports or weakens the classification; storing a plurality of determined criteria; and determining, by the processing unit, a probability of the classification being correct with the aid of Bayes filtering of the at least one criterion, the probability being determined based on the stored criteria.

15. A device for classifying surroundings of a motor vehicle into one of multiple predefined classes, comprising:
-
an estimating device for providing a classification regarding one of multiple predefined classes to which the surroundings belong, the multiple predefined classes including at least two of a freeway class, a traffic-calm zone class, a city traffic zone class, or a parking situation class; an interface for receiving sampled pieces of information from the surroundings of the motor vehicle; a processing device for (i) determining, based on the sampled pieces of information, at least one criterion which supports or weakens the classification, and (ii) determining a probability of the classification being correct with the aid of Bayes filtering of the at least one criterion; and a memory for storing the at least one criterion. - View Dependent Claims (16)

17. A method for indicating surroundings of a motor vehicle to a driver assistance system of the motor vehicle, comprising:
-
providing, by an estimating unit, a classification regarding one of multiple predefined classes to which the surroundings belong, the multiple predefined classes including at least two of a freeway class, a traffic-calm zone class, a city traffic zone class, or a parking situation class; receiving, from a sampling device, sampled pieces of information from the surroundings of the motor vehicle; determining, by a processing unit, based on the sampled pieces of information, at least one criterion which supports or weakens the classification; determining, by the processing unit, a probability of the classification being correct with the aid of Bayes filtering of the at least one criterion; accepting the classification if the probability exceeds a threshold; and providing a signal indicating the surroundings of the motor vehicle to the driver assistance system of the motor vehicle. - View Dependent Claims (18, 19, 20, 21, 22)
