Abstract:
An ultrasonic measurement apparatus is described having a receiving device which determines a measurement sequence relating to a time variation of the period lengths of an ultrasonic signal received from an in-vehicle and/or external ultrasonic transmitter, a comparison device which determines a comparison information item relating to a deviation of the determined measurement sequence from at least one reference sequence, and an evaluation device which determines, taking into consideration the determined comparison information item, an information item relating to a signal form transmitted by the ultrasonic transmitter, a relative speed between the receiving device and the ultrasonic transmitter, a relative speed of at least one reflecting object situated in a transmission path between the receiving device and the ultrasonic transmitter, and/or a shape feature of the at least one reflecting object. A method for evaluating an ultrasonic signal is also described.
Abstract:
In a method for determining the position and/or the movement of an object in the vicinity of a vehicle, received echo signals that have been reflected off of the object are each amplified by an amplification that is dependent on the propagation delay of the corresponding echo signal, and amplified echo signals of a plurality of measuring channels are each converted into a value-discretized and/or time-discretized measurement signal having a predefined, first dynamic range; and the measurement signals, which each have the first dynamic range, are mapped onto a second dynamic range of a processing device that is larger than the first dynamic range, in a way that allows them to be at least periodically simultaneously processed by the processing device.

Abstract:
A bus station or a communication system is described, where the bus stations receive communications containing transmission information from which the position of the transmitting bus station in a sequence of bus stations can. A time slot for the bus station in which the bus station repeats the received communication is calculated from the transmission information and position information stored in the bus station indicating the position of the bus station in the sequence. These bus stations are especially suitable for data exchange by radio.
Abstract:
A method for amplifying an echo signal, in which an analog echo signal suitable for detection of a vehicle's surroundings is amplified by a gain dependent on the transit time of the echo signal, the analog echo signal being amplified by an amplifier having a plurality of outputs, each having a different gain, and a downstream A/D converter having a time-variable reference voltage. In the process, there is a switch between the different outputs of the amplifier at predefined switching points in time, and the reference voltage of the A/D converter varies over time between the switching points in time in such a way that the echo signal is present at the output of the A/D converter with a transit time-dependent total gain having a predefined characteristic.
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 to signature of the ultrasonic pulse differs from that of the decay signal. The evaluation unit is designed to recognize the echo pulse based on an evaluation of a correlation signal which is generated with the aid of at least one correlation filter and which originates from the correlation of the signal generated by the resonant transducer element with the transmitted signal. Furthermore, a corresponding method is provided for detecting an obstacle with the aid of ultrasound, as well as a vehicle assistance system having the ultrasonic measuring system.
