摘要： A method for classifying the height of an object by at least one vehicle ultrasonic sensor is disclosed. A computer receives at least two ultrasonic signals, calculates a first item of height information based on two items of spacing information relating to at least one vehicle ultrasonic sensor and the object, and calculates a variance of the first item of information. The computer similarly calculates a second item of height information and a variance thereof from a received further ultrasonic signal. The computer combines the items of height information as an average thereof, and the calculated variances of items of height information as an averaged variance thereof. The object is classified in a height class by calculating a probability value based on a distribution function which has as a mean value the averaged item of height information and as a variance the averaged variance of the height information.

摘要： The invention relates to a method for identifying parking spaces, including emitting an ultrasonic signal and receiving a reflected signal; and providing a grid which of a region having a plurality of cells. Each cell is assigned to a partial region of the region surrounding the vehicle and an occupancy value is assigned to each cell. The reflected signal is assigned to a set of cells of the grid based on a transit time of the ultrasonic signal between emission and reception. The occupancy values of the cells to which the reflected signal is allocated are increased by a specific value. An occupancy information item is determined based on the occupancy values of the cells. The signal emitting/receiving and the reflected signal assigning are repeated multiple times. Parking space identification is performed based on an occupancy status of the cells specified using the occupancy information item determination.

摘要： This disclosure relates to a computer-implemented method for processing sensor data points by means of a data processing hardware where a distributions buffer for storing an initial plurality of Gaussian distributions is initialized, each Gaussian distribution of the initial plurality of Gaussian distributions including an initial plurality of sensor data points received sequentially from at least one sensor and having an associated predetermined distribution distance threshold, and where the distributions buffer is sequentially updated for a number n of new sensor data points based on a distribution distance condition, generating an updated plurality of Gaussian distributions including either a new Gaussian distribution, or an updated single Gaussian distribution or an updated merged Gaussian distribution.

摘要： A method for classifying the height of an object by means of at least one ultrasonic sensor of a vehicle is disclosed. The method includes emitting an ultrasonic signal by the ultrasonic sensor of the vehicle in a transmission cycle; and performing a reception cycle, wherein the reception cycle has a reception time window which makes it possible to receive echoes having a transit time which corresponds to at least double a reception range of the ultrasonic sensor. It is checked whether echoes were received in the reception cycle. A detected object is classified in a height class depending on whether at least a first and a second echo were received, wherein the transit time of the second echo is an integer multiple of the transit time of the first echo.
