A sensor assembly of a vehicle. The sensor includes a control device, a multitude of sensors, each sensor having an individual sensor identifier, a data bus, which connects each sensor to the control device, and a supply line, which connects each sensor to the control device for a voltage supply. Each sensor has a shunt resistor. All shunt resistors are integrated in series into the supply line. Each sensor is developed to detect a voltage drop at its respective shunt resistor. The control device is developed to actuate each sensor with the aid of the individual sensor identifier and to assign an individual geographical address to each sensor based on the detected voltage drops along the supply line.

Sensor assembly of a vehicle

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.

An operating method for an ultrasound transceiver device, where the ultrasound transceiver device is alternately and, in particular alternatingly operated in a transmit mode and in a receive mode; subsequently to a transmit mode and/or prior to a receive mode, the ultrasound transceiver device is actively damped by the action of a sequence of counter control pulses; a phase position and/or a damping energy are/is iteratively determined or adapted via a training by a measure of the damping success at least temporarily assuming or approaching an at least locally optimal value.

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.
