Abstract: Example embodiments of the present disclosure provide a map updating method and apparatus, a device and a computer-readable storage medium, which may be applied to a field of autonomous driving. The map updating method includes determining that there is an interruption on a road edge of a road on a map, the road edge representing a boundary of a part of the road available for vehicles. The method further includes determining, based on the map, a reference distance between an existing part of the road edge and a division line, the existing part being within a predetermined distance from the interruption, and the division line representing a division between different traveling directions of the road. The method further includes generating a supplementary part for the interruption on the map based on the reference distance and the division line.
