Vehicle Map Data Layers for Bandwidth-Efficient Client Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently managing and communicating vehicle map service data across various client systems, including vehicles and remote computing systems, due to varying hardware and operational changes over time, leading to inefficiencies in data access and communication.
Innovation Solution
A vehicle map service system that utilizes a protocol-based data layer approach, allowing client systems to subscribe to specific layers of data, enabling authorized access and communication of vehicle map service data, including geographic information and sensor observations, between vehicles and remote systems, using a publish/subscribe model to ensure efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all vehicle map service data is transferred to all client systems, then complete data availability is achieved, but data transfer redundancy and network bandwidth consumption increase significantly
Solution Approach 1:
The patent segments vehicle map service data into multiple distinct layers (e.g., geographic information layer, sensor observations layer, map updates layer). Each layer represents a specific type of data that can be independently subscribed to by client systems. This segmentation allows the server to send only the specific layers that individual clients need, rather than transferring all data to all clients, thereby reducing network bandwidth consumption while maintaining data availability for subscribed layers.
2Productivity
If a protocol-based layer system is implemented, then data transfer efficiency and relevance are improved, but system complexity increases due to protocol specification and layer management
Solution Approach 1:
The patent implements a universal protocol-based layer system that can handle multiple types of vehicle map service data (geographic information, sensor observations, map updates) through a common framework. The protocol defines standard mechanisms for data subscription, publication, and transfer that work across different data types and client systems. This universal approach improves data transfer efficiency by providing standardized, optimized pathways for data flow, while the modularity of the layer system keeps complexity manageable through consistent interface design.
3Loss of energy
If selective data subscription is enabled, then network bandwidth is optimized, but data access complexity increases for managing subscriptions and permissions
Solution Approach 1:
The patent introduces an intermediary protocol layer that manages data subscriptions and access permissions between client systems and the vehicle map service data. The protocol handles subscription requests, layer availability verification, and authorized data transfer automatically. This intermediary mechanism optimizes network bandwidth by enabling selective data subscription while reducing the complexity of managing subscriptions and permissions, as the protocol encapsulates the management logic in standardized procedures rather than requiring complex custom implementations.

AI summary
Provided are methods, systems, devices, and tangible non-transitory computer readable media for providing data including vehicle map service data. The disclosed technology can perform operations including accessing vehicle map service data including information associated with a geographic area and sensor observations of a vehicle. The vehicle map service data is based on a vehicle map service protocol specifying layers associated with portions of the vehicle map service data to which each client system is subscribed. Further, the layers to which the client systems are subscribed can be determined and access to the plurality of layers to which each of the vehicle client systems is subscribed can be provided to each of the client systems. Access to the layers can include authorization to send or receive one or more portions of the vehicle map service data associated with a corresponding layer.
