Abstract

According to the invention, a method is provided for detecting objects from the vehicle environment of a vehicle, in which a plurality of signals, in particular electrical signals, suitable for signal processing, and which are generated from acoustic signals, are analysed relative to comparable features and, in the event of a potential collision of the vehicle with a detected object, a warning is emitted to the driver and / or the vehicle dynamics are actively acted upon and / or functions for reducing or avoiding a severe accident are activated. In the method according to the invention, for detecting at least one first object from the vehicle environment, acoustic signals are used from the vehicle environment, said signals impinging on the vehicle from at least one first predefined direction and comprising intrinsic noise generated by the vehicle, depending on the function, and / or external noise from the vehicle environment.

Description

Technical field

[0001] The invention relates to a method and a device for detecting objects in the surrounding environment of a vehicle. The invention also relates to a vehicle assistance system with a device according to the invention. Background technique

[0002] For the detection of the acoustic surroundings of the vehicle, the ultrasonic system that performs measurement in pulses is usually used at present, in which a short signal pulse of 0.3ms is transmitted, and the object is determined according to the propagation time of the reflection of the pulse on the object in the surrounding environment and the speed of sound the distance.

[0003] For acoustic ambient monitoring, the ultrasonic frequency range is used, because usually the intensity of interference noise in the surrounding environment decreases as the frequency increases. However, since the spatial attenuation increases with the increase of the signal frequency, the lower region of the ultrasonic frequency band of...
