  • Patent number: 11313957
    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.

  • Publication number: 20210125429
    Abstract: A sensor, including at least one transducer for emitting signals and for receiving reflected echo signals, the transducer being set up to output an analog measuring signal, an analog-to-digital converter for converting the analog measuring signal into a digital measuring signal, an evaluation unit for evaluating the digital measuring signal, and a communication unit for transmitting a measuring result of the evaluation via a digital communication interface. The communication unit is equipped to receive a request for diagnostic data via the digital communication interface, and is also equipped to switch the sensor to diagnostic operation and to transmit requested diagnostic data via the digital communication interface. The communication unit is set up to communicate with at least two different data rates via the digital communication interface, a higher data rate being used for transmitting the diagnostic data than for transmitting the measuring result during normal operation of the sensor.

  • Patent number: 9557168
    Abstract: An ultrasonic measuring system is described for detecting an obstacle using a resonant transducer element for transmitting an ultrasonic pulse and for generating a received signal which includes the ultrasonic echo pulse reflected from the obstacle, the transducer element generating a decay signal having its resonance frequency after transmitting an ultrasonic pulse. The ultrasonic measuring system includes an evaluation unit having a control unit which is designed to activate the transducer element for transmitting the ultrasonic pulse with the aid of a frequency-modulated transmitted signal generated by the control unit, the frequency modulation taking place with the aid of a modulation signal in such a way that the signature of the ultrasonic pulse differs from that of the decay signal.

  • Patent number: 9255991
    Abstract: A method for acoustically sensing an area is described. An acoustic transmit pulse is transmitted into the area by an acoustic transducer and a received signal is acquired with the aid of the transducer, in order to receive the transmit pulse reflected back from the area. Within a post-pulse oscillation time of the transducer, which directly follows the emission of the transmit pulse, the actual phase response of the received signal is determined. In the event the actual phase response deviates from a predefined setpoint phase response, an object is detected within the area. Also described is a device for acoustically sensing an area, which is designed to carry out the method.

  • Patent number: 9140791
    Abstract: In a method for functional testing of an ultrasonic sensor on a motor vehicle, the ultrasonic sensor is controlled in such a way that it emits an ultrasonic signal having a frequency of a secondary mode of the ultrasonic sensor, the ultrasonic signal is reflected by a surface in the region around the vehicle, and at least one transmission path or one transmitting unit of the ultrasonic sensor is classified as functional if the reflected signal is received by the ultrasonic sensor itself or by another ultrasonic sensor on the motor vehicle.
