AI Technical Summary
Technical Problem
Existing navigation systems face challenges in efficiently communicating data between vehicles and external service servers due to differences in digital maps and georeferencing methods, leading to increased computational effort and data transmission requirements.
Method used
A support system generates a unique code for map references, allowing vehicles to decode georeferences independently and minimizing data transmission by storing these codes in memory, thus reducing the need for repeated communication with the support system.
Benefits of technology
This approach minimizes data transmission and computational effort by using a unique identifier for map references, enabling efficient data communication and scalability across different georeferencing methods and map formats.

Abstract
Method for supporting data communication between a computing unit (2) of a vehicle (1) and at least one vehicle-external service server (10) using a support system (8) separate from the vehicle (1) and the service server (10), which communicates with the computing unit (2) of the vehicle (1) and the at least one service server (10), comprising the steps: - Receiving a georeference (GR) by the support system (8) from the service server (10) and determining a map-specific map reference (KR) associated with the received georeference (GR) in a digital map of the support system (8) by the support system (8) using a georeferencing procedure associated with the received georeference (GR), - Generating a unique code (X1 to XX) for the determined map reference (KR) by the support system (8) and storing the code (X1 to XX) assigned to the determined map reference (KR) and / or the received georeference (GR) in a memory of the support system (8), wherein the code (X1 to XX) is formed by a smaller amount of data compared to the received georeference (GR), - Receiving the code (X1 to XX) by the computing unit (2) of the vehicle (1), - Transmission of a request message with the code (X1 to XX) from the computing unit (2) of the vehicle (1) to the support system (8), wherein the request message instructs the support system (8) to transmit to the computing unit (2) of the vehicle (1) a georeference (GR) associated with the code (X1 to XX) and generated according to a georeferencing procedure defined by the request message and / or a map reference (KR) associated with the code (X1 to XX) and suitable for a digital map format defined by the request message, and - Transferring the georeference (GR) and / or the appropriate map reference (KR) defined by the request message from the support system (8) to the computing unit (2) of the vehicle (1) based on the received request message.
