Abstract: An electronic map update method includes: determining an update period of a first electronic map corresponding to a user equipment in response to a map update request sent by the user equipment; determining at least one piece of per-period incremental information currently corresponding to a second electronic map of a latest version; where the per-period incremental information includes an incremental period, the per-period incremental information is a data change record of an electronic map in the incremental period, and the incremental period is a period for starting an incremental conversion of the electronic map; querying, from the at least one piece of per-period incremental information, target incremental information of which a corresponding incremental period is located in the update period; and updating the first electronic map of the user equipment to the second electronic map based on the target incremental information.
