Abstract: A method for classifying at least one object in the surroundings of a vehicle using an ultrasonic sensor system. The method includes: emitting ultrasonic signals at a plurality of successive time points using the ultrasonic sensor system; and receiving ultrasonic echo signals reflected on the one or more objects in the surroundings of the vehicle, using the ultrasonic sensor system; wherein one or more objects in the surroundings are ascertained as a function of the received ultrasonic echo signals, and wherein it is determined as a function of the received ultrasonic echo signals whether the respective object is classified as dynamic, in particular as a pedestrian. A controller for operating an ultrasonic sensor system, an ultrasonic sensor system, and a vehicle including such an ultrasonic sensor system are also described.

Abstract: A method for providing training datasets for training an object classification model for object classification in an ultrasonic sensor system is disclosed.

Abstract: A method for evaluating an height of an object in the surrounding environment of a vehicle, using ultrasonic signals acquired by an ultrasonic sensor mounted on the vehicle. In a measurement cycle, a first ultrasonic signal is acquired as an edge reflection or as a directly traveling echo of an object. An expectation window is calculated for an associated interior-corner reflection. A second ultrasonic signal acquired in the expectation window is recognized as an interior-corner reflection associated with the first ultrasonic signal. The first and second ultrasonic signals are combined to form a signal group. A significance is determined for each ultrasonic signal. The signal group is assigned to a first or second echo group. The rates of the assignment to the first and to the second echo group are determined over a number of measurement cycles. An evaluation of the height is based on the first and second rates.

Abstract: A method for classifying objects in the surroundings of a vehicle using ultrasonic sensors which emit ultrasonic pulses and receive ultrasonic echoes reflected by objects. Distances between the sensors and objects reflecting ultrasonic pulses are ascertained via at least two ultrasonic sensors including overlapping fields of vision, and a position determination of the reflecting objects taking place using lateration and the assignment of the received ultrasonic echoes to object hypotheses for distinguishing between extensive objects and point-like objects.

Abstract: A method for evaluating an effect of an object in the surroundings of a transport device on a driving maneuver of the transport device. The method includes: ascertaining a first distance between the object and a first position of the transport device with the aid of a first ultrasonic sensor of the transport device; ascertaining a second distance between the object and a second position of the transport device different from the first position, using the first ultrasonic sensor of the transport device; calculating a change between the first distance and the second distance with regard to a path, which corresponds to a distance traveled between the first position and the second position of the transport device; and taking into account or not taking into account the object during the execution of the driving maneuver of the transport device as a function of a result of the calculation.

Abstract: A method for monitoring the surroundings of a vehicle, the surroundings behind the vehicle being detected with the aid of ultrasonic sensors and with the aid of at least one imaging sensor, a warning signal being output when an object that has a distance to the vehicle smaller than a predefined minimum distance is detected with the aid of ultrasonic sensors, a trailer of the vehicle being recognized with the aid of the imaging sensor, and the warning signal not being output when the object is the trailer recognized by the imaging sensor.

Abstract: A method for avoiding a collision of a vehicle with an obstacle, using at least one ultrasonic sensor. Reflection points are determined during a movement of the vehicle, the reflection points representing locations at which a signal of an ultrasonic sensor was reflected. The reflection points are combined into contiguous, linearly extending wall sections, a wall section having two ends. Furthermore, it is determined whether an end of a wall section is open or closed. The progression abutting an open end of a wall section is extrapolated, and virtual collision points between the vehicle and the extrapolated progression of the wall sections are ascertained. An initiation of a brake intervention follows if a collision with a virtual collision point is imminent. A driver assistance system including at least one ultrasonic sensor configured to carry out the method, and a vehicle including such a driver assistance system, are also described.
