Abstract
An edge device for providing an HD map to a vehicle is provided. The edge device includes a controller programmed to obtain an HD map request including a task type from a vehicle, obtain a status of a wireless channel between the vehicle and the edge device, determine an HD map version among a plurality of versions based on the status of the wireless channel and the task type, and transmit the determined HD map version to the vehicle.
Claims18
An edge device comprising:
- a controller programmed to:
- obtain an HD map request including a task type of operating a vehicle from the vehicle;
- obtain a status of a wireless channel between the vehicle and the edge device;
- determine an HD map version among a plurality of HD map versions based on the status of the wireless channel and the task type of operating the vehicle, each of the plurality of HD map versions including different one or more layers of an HD map;
- determine whether the determined HD map version is stored in a database of the edge device;
- transmit a request for the determined HD map version to a cloud server in response to determining that the determined HD map version is not stored in the database;
- and
- transmit the determined HD map version to the vehicle in response to determining that the determined HD map version is stored in the database.
