Abstract: A method for recognizing a noise represented in a receive signal of an ultrasonic sensor. A characteristic spectrum of the noise is compared with a noise spectrum of the receive signal, the noise spectrum including at least two noise levels determined in different frequency bands of the receive signal.

Abstract: A method for measuring precipitation. The method includes a read-in step, a detection step and a determination step. In the read-in step, data packets of at least one ultrasonic sensor are read in. Excitations detected by the ultrasonic sensor within a measuring time window are mapped in a data packet. The excitations are mapped as time values and intensity values. The time value represents a detection point in time of an excitation. The intensity value represents an amplitude of the excitation. In the detection step, excitations are detected as drop events. An excitation is detected as a drop event induced by a pulse of an impacting drop if the time value and/or the intensity value of the excitation satisfies at least one characteristic of a drop event. In the determination step, a precipitation intensity is determined, using a number of drop events detected per time unit.

Abstract: An ultrasonic system of a vehicle. The ultrasonic system includes: at least one ultrasonic sensor for ascertaining a distance of objects from the vehicle by comparing an emitted signal and a reflected echo, and a calculation apparatus for evaluating a measured signal of the ultrasonic sensor. The calculation apparatus is configured to determine a variance of a ground echo distribution within a roadway portion on which the vehicle is moving, and to ascertain the condition of the roadway portion on the basis of at least one predefined classifier that associates individual values of the variance with a roadway condition.

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.

Abstract: A method for operating a motor-driven sports device, in which a maximum speed of the sports device is at least intermittently restricted as a function of a position of the sports device. A device for operating a motor-driven sports device is described, the device including a position-ascertainment unit which is set up for ascertaining the position of the sports device; a speed-ascertainment unit which is set up for ascertaining an actual speed of the sports device; an allocation unit which is set up for allocating a permitted maximum speed to the position of the sports device; a comparison unit which is set up for comparing a permitted maximum speed to an actual speed; and a restriction unit which is set up for restricting a maximum speed of the sports device if the actual speed exceeds the permitted maximum speed.
