Abstract

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.
