Abstract
A method and apparatus for the determination of a stationary and/or moving object, such as a vehicle, acoustic signals emitted by the object and/or reflected by another object are recorded and used to evaluate or identify an object. The object is detected, evaluated and identified acoustically with the aid of noises from it and/or extraneous noises, with respect to its own movement profile in relation to one or more coordinate axes (x, y axes), in the manner of a self-localization based on sound waves.

20. A method for determining a stationary or moving object, comprising:
-
recording acoustic signals emitted by a first object or reflected by a second object, as a reference signal;
using the recorded reference signal to detect, evaluate or identify the first or second object; and
calculating or projecting a movement state or movement profile pertaining to the first or second object, based on the recorded acoustic signals. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A device for determining a stationary or moving object, comprising:
-
at least one sonic transducer system having a directional characteristic for recording acoustic signals emitted by a first object or reflected by a second object; and
an evaluation unit for detecting, evaluating or identifying the first or second object based on recorded acoustic signals;
wherein,the sonic transducer system comprises a plurality of sound sensors for multidirectional recording of acoustic signals or object-related noise signals for direction-related self-localization; and
the sonic transducer system and the evaluation unit form a passive acoustic radar based on sound waves. - View Dependent Claims (34, 35, 36, 37)

38. A method for detecting and evaluating an object which is situated in proximity to a vehicle, said method comprising:
-
recording and storing as reference signals, first sound signals emanating from the vehicle;
recording second sound signals including sounds emanating from or reflected by said object; and
using said recorded reference signals and said recorded second sound signals to detect, evaluate or identify said object, including calculating or projecting a movement state or movement profile for the object, based on said signals.
