A computer implemented method for determining an entry of an occupancy map of a vicinity of a vehicle comprises the following steps carried out by computer hardware components: acquiring first sensor data of a first sensor of the vicinity of the vehicle; acquiring second sensor data of a second sensor of the vicinity of the vehicle; determining a first sensor data portion of the first sensor data which corresponds to a potential object in the vicinity of the vehicle; based on the first sensor data portion, determining a second sensor data portion of the second sensor data which corresponds to a location of the potential object; and determining an entry of the occupancy map based on the first sensor data portion and the second sensor data portion.
