DIGITAL MAP FOR NAVIGATION
20230031344 · 2023-02-02 ·

A digital map representing a physical location as a hierarchical structure of cells. Each cell has attributes including but not limited to permeability in each direction of a three-dimensional coordinate system and associated with one or more faces or edges of a boundary. The permeability pertains separately to transmissions of radio frequency signals and to physical travel of objects and persons.

Map Data Updating Method And System

The invention is a map data updating method for updating map data on a client device (10) by means of a server (11) storing a latest version of the map data, wherein the map data comprises map tiles having layers. The server (11) stores association information defining groups of associated layers, wherein each layer in a group is updated on the client device (10) if an update request for at least one layer in the group is received by the server (11) from the client device (10). The invention also relates to a map data updating system, a computer program product and a computer-readable medium for implementing the method.

Technologies for managing interoperable high definition maps for autonomous vehicles

Technologies for managing interoperable high definition (HD) maps for autonomous vehicles includes a HD map server to distribute interoperable HD map tiles to various autonomous vehicles, each of which may be configured to utilize proprietary HD map tiles of different propriety formats. As such, each of the autonomous vehicles is configured to translate the interoperable HD map tile to the proprietary format used by that particular vehicle. Additionally, each autonomous vehicle may submit crowd-sourced sensor data to the interoperable HD map server using a universal data set by converting the sensor data to a universal data structure.

The present disclosure relates to a vehicular electronic device including a power supply configured to supply power, an interface configured to receive HD map data on a specific area from a server through a communication device and receive data on driving condition information of a vehicle, and a processor configured to continuously generate electronic horizon data on a specific area based on the high-definition (HD) map data in the state of receiving the power and to set a geographical range of the electronic horizon data based on data on the driving condition information.

HIGH DEFINITION MAPPING FOR AUTONOMOUS SYSTEMS AND APPLICATIONS
20220349725 · 2022-11-03 ·

In various examples, a high definition (HD) map is provided that includes a segmented data structure that allows for selective access to desired road segments and corresponding layers of map data. For example, the HD map may be segmented into a series of tiles that may correspond to a geographic region, and each of the tiles may include any number of road segments corresponding to portions of the geographic region. Each road segment may include a corresponding set of layers—which may include driving layers for use by the ego-machine and/or training layers for generating ground truth data—from the HD map that are associated with the road segment alone. As such, when traversing the environment, an ego-machine may determine one or more road segments within a tile corresponding to a current location, and may selectively download one or more layers for each of the one or more road segments.

Method and apparatus for supporting user interactions with non- designated locations on a digital map

A mapping system allows a user to interact with any location on a digital map and present the user with location related information associated with the selected location. The location related information may be in the form or a card, pop-up, image, or other graphic and may be displayed on the map at or near the selected location, around the map, etc. The displayed location related information may include predetermined or pre-stored data about the location or may include location related information collected and generated on the fly in response to the user interaction with the digital map. The displayed location related information may be displayed in the same graphical format on the digital map regardless of whether location related information is predetermined information about the location that already exists or information that is collected and generated on the fly in response to the user interaction.
