The invention relates to a method for operating a sensor arrangement () having a control unit () and a plurality of sensors () which are arranged in at least one group (), wherein the sensors () are connected to a common electrical supply, in particular via the control unit (), comprising the steps of using the sensors () to emit sensor signals, wherein the sensors () in each group () emit the sensor signals thereof in the particular group transmission phase thereof, receiving echo signals on the basis of reflections of the sensor signals, transmitting the received echo signals from the sensors () to the control unit (), and identifying interference () in the received echo signals from the at least one group () on the basis of a comparison of at least two of the received echo signals from the corresponding group (). The invention also relates to a corresponding sensor arrangement () for a vehicle () for operation according to the above method. The invention also relates to a driving assistance system for a vehicle () having a sensor arrangement () as described above.

Identifying interference in received echo signals from a group of sensors

The present invention relates to a method for measurement by means of an ultrasonic sensor system in an interfering environment, for example in a magnetic field, for a vehicle, the method comprising the following method steps: emitting, by means of an ultrasonic sensor system, ultrasound with at least one frequency range (); receiving, by means of an ultrasonic sensor system, an echo () produced by the ultrasound; outputting, by means of an ultrasonic sensor system, a signal corresponding to the echo to a control system (); detecting, by means of a detection system, noise of the signal (); determining, by means of the control system, whether there is interference in the at least one frequency range, on the basis of the noise of the signal (); and, if interference is determined, emitting, by means of the ultrasonic sensor system, ultrasound with at least one frequency range () for which no interference is determined. The present invention also relates to a device for measurement by means of an ultrasonic sensor system in a magnetic field, for a vehicle, to a vehicle having the device, to a computer program, to a data carrier signal, which transmits the computer program, and to a computer-readable medium.
