Abstract

The invention provides a map updating method and equipment, and belongs to the technical field of intelligent traffic, and the map updating method comprises the steps: receiving road traffic information collected and transmitted by vehicle-side equipment and / or roadside equipment; according to the road traffic information, updating an area map corresponding to the jurisdiction area of the edge network equipment; and sending the updated area map to the core network equipment and / or roadside equipment in the jurisdiction area of the edge network equipment. The invention is short in map updating period and high in timeliness.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for updating a map. Background technique [0002] It is predicted that by 2040, smart transportation service providers will account for as much as 55% of PKMT (total passenger kilometers by vehicle type), and privately owned self-driving vehicles will only account for 11%. Simultaneous growth with travel services, and high-precision maps, as a rigid requirement for high-precision positioning technology, are one of the key capabilities to achieve autonomous driving, and will become an effective supplement to existing sensors for autonomous driving, providing vehicles with safer and more reliable perception ability and driving experience. Compared with traditional navigation electronic maps, high-precision maps serving autonomous driving have higher requirements in all aspects, and can cooperate with sensors and algorithms to provide supp...
