  • Publication number: 20200371219
    Abstract: A method for monitoring the function of ultrasonic sensors of a vehicle, an ultrasonic sensor of the vehicle emitting ultrasonic signals and receiving back reflected ultrasonic echoes. An instantaneous amplitude of a ground echo received by an ultrasonic sensor and an instantaneous vehicle position are determined. A reference threshold value or information regarding an expected ground echo amplitude is retrieved from a digital map as a function of the instantaneous vehicle position, the digital map being provided by a central unit. The instantaneous amplitude of the received ground echo is compared with a threshold value, a malfunction of the ultrasonic sensors being deduced if the threshold value is undershot and the threshold value being predefined by the reference threshold value or the threshold value being determined based on the information regarding an expected ground echo amplitude.

  • Patent number: 10838060
    Abstract: A method for detecting at least one object between primary and secondary coils of a vehicle's inductive-charging-device. A first ultrasonic signal (FUS) is emitted with a first ultrasonic-transmitter (UT) situated at the primary-coil. A FUS-sequence is received with a first ultrasonic-receiver (FUR) at the vehicle. The FUS-sequence includes at least one first direct-receive signal. Alternatively/in addition, the FUS sequence includes additional receive signals, each of which corresponds to an indirect transmission of the ultrasonic-signal from the at least one UT to the FUR. The first direct receive signal is ascertained within the FUS-sequence and/or additional receive signals are ascertained within the FUS-sequence. The first received ultrasonic-signal-sequence, which includes the ascertained direct-receive-signal and/or ascertained additional receive signals is compared to a first reference-ultrasonic-signal-sequence.

  • Publication number: 20200341129
    Abstract: A method for detecting a ground echo signal of an ultrasonic sensor of a vehicle. The ultrasonic sensor emits a signal at a first frequency or having a first frequency profile, the signal is reflected by a roadway surface and the reflected signal is received by the ultrasonic sensor and/or by an additional ultrasonic sensor. The received echo signal is filtered with the aid of a matched filter, the matched filter being adapted to the emitted signal and having a characterizing frequency. In this way a ground echo signal is determined from the filtered signal. The instantaneous vehicle speed is determined and an expected Doppler shift of the reflected signal is determined as a function of the instantaneous vehicle speed. The first frequency or the first frequency profile and/or the characterizing frequency of the matched filter is/are adapted as a function of the Doppler shift to be expected.

  • Publication number: 20200284891
    Abstract: A method and device for processing an echo signal received from an acoustic sensor. The echo signal is detected over a measurement time interval. A minimum value is ascertained, which describes a minimum amplitude of the echo signal within the measurement interval. An amplitude value is ascertained, which describes an amplitude of the echo signal within a measurement window. The measurement window is a predefined time interval within the measurement interval. A difference is ascertained between the minimum value and the amplitude value. A determination is made whether the echo signal comprises an interference signal of the first type or an interference signal of the second type, based on the ascertained difference.
