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： The present disclosure present disclosure relates to a method for characterizing an object in an environment of a motor vehicle by an assistance system of the motor vehicle, in which method the motor vehicle is moved relative to the object and ultrasonic signals are emitted with an ultrasonic sensor of the assistance system. Echoes of the ultrasonic signals reflected by the object are received, wherein, by a control device, respective amplitudes of the received echoes are ascertained, and a classification of a height of the object is determined based on the amplitudes. present disclosure The classification of the height of the object is determined based on a determined first change in amplitude by comparing a first amplitude of a first echo with a second amplitude of a second echo received after the first echo. present disclosure An assistance system is disclosed having an ultrasonic sensor and a control device designed to carry out such a method.
