Abstract: The present disclosure relates to a method and device for generating a lane polyline by using a neural network model.
The method according to an embodiment of the present disclosure may include generating a bird's-eye-view feature based on a base image obtained from at least one sensor mounted on a vehicle, and training a neural network model by using the bird's-eye-view feature as input data for the neural network model and using a lane polyline for a certain road as output data. In the present disclosure, a lane polyline obtained from the above-described neural network model may be used for controlling the vehicle without performing a separate process on the lane polyline.

Abstract: Provided are a method and apparatus for performing authentication on a vehicle on-demand service. A method by which an integrated communication control unit performs authentication on a vehicle on-demand service, includes: storing, in a service authentication server, a first option value related to a vehicle service, received from a tool in factory (TIF) device; obtaining or generating a private root private key and a private root certificate; generating a device certificate and a device private key signed with the private root private key for each performance controller; generating a service token for the first option value by using the private root certificate and the private root private key; and transmitting the generated service token, the private root certificate, and the device private key for each performance controller.

Abstract: The present disclosure relates to a method and apparatus for performing multipath search. The method according to an embodiment of the present disclosure may calculate a distance between an origin point and a destination point in a group of destination points. In addition, the method may generate a travel path between the origin point and the destination point using a first path-finding method when the distance between the destination point and the origin point is less than a threshold value, and generate the travel path between the origin point and the destination point using a second path-finding method when the distance between the destination point and the origin point is greater than or equal to the threshold value.
