Method for identifying parking spaces by means of at least one ultrasonic sensor of a vehicle, comprising the following steps: a) emission of an ultrasonic signal by an ultrasonic sensor of the vehicle; b) reception of a reflected signal component of the ultrasonic signal by the ultrasonic sensor; c) provision of a grid, which refers to a region surrounding the vehicle, wherein the grid has a plurality of cells, wherein each cell is assigned to a subregion of the region surrounding the vehicle and an occupancy value is assigned to each cell; d) assignment of the reflected signal component to a set of multiple cells of the grid based on the propagation time of the ultrasonic signal between the emission and the reception of the reflected signal component, wherein the occupancy values of the cells to which the reflected signal component is allocated are in each case increased by a specific value; e) determination of an item of occupancy information based on the occupancy values of the cells of the set of cells by: 1. determination of that cell of the set of cells that has the maximum occupancy value (BW max); 2. comparison of the maximum occupancy value (BW max) with a first threshold value; 3. if the maximum occupancy value (BW max) exceeds the first threshold value, changing of a counter (n), which is assigned to the cell having the maximum occupancy value (BW max), by an incremental value; and 4. comparison of the counter (n) with a second threshold value and specification of an occupancy status of the cell depending on the comparison result; f) multiple repetition of steps a), b), d) and e); and g) performance of parking space identification based on the occupancy status of the cells of the grid. a) emission of an ultrasonic signal by an ultrasonic sensor of the vehicle; b) reception of a reflected signal component of the ultrasonic signal by the ultrasonic sensor; c) provision of a grid, which refers to a region surrounding the vehicle, wherein the grid has a plurality of cells, wherein each cell is assigned to a subregion of the region surrounding the vehicle and an occupancy value is assigned to each cell; d) assignment of the reflected signal component to a set of multiple cells of the grid based on the propagation time of the ultrasonic signal between the emission and the reception of the reflected signal component, wherein the occupancy values of the cells to which the reflected signal component is allocated are in each case increased by a specific value; e) determination of an item of occupancy information based on the occupancy values of the cells of the set of cells by: 1. determination of that cell of the set of cells that has the maximum occupancy value (BW max); 2. comparison of the maximum occupancy value (BW max) with a first threshold value; 3. if the maximum occupancy value (BW max) exceeds the first threshold value, changing of a counter (n), which is assigned to the cell having the maximum occupancy value (BW max), by an incremental value; and 4. comparison of the counter (n) with a second threshold value and specification of an occupancy status of the cell depending on the comparison result; f) multiple repetition of steps a), b), d) and e); and g) performance of parking space identification based on the occupancy status of the cells of the grid. 1. determination of that cell of the set of cells that has the maximum occupancy value (BW max); 2. comparison of the maximum occupancy value (BW max) with a first threshold value; 3. if the maximum occupancy value (BW max) exceeds the first threshold value, changing of a counter (n), which is assigned to the cell having the maximum occupancy value (BW max), by an incremental value; and 4. comparison of the counter (n) with a second threshold value and specification of an occupancy status of the cell depending on the comparison result; f) multiple repetition of steps a), b), d) and e); and g) performance of parking space identification based on the occupancy status of the cells of the grid. f) multiple repetition of steps a), b), d) and e); and g) performance of parking space identification based on the occupancy status of the cells of the grid.
